Abstract

Introduction: Antibiotics alongside with analgesics and local anaesthetics are the most frequently used drugs in dentistry. Reliably structured figures concerning the actual number of prescriptions of antibiotics by dentists are hardly available.

Materials & Methods: All antibiotic prescriptions of dentists for patients who are members of statutory health insurances in Germany from 1 January 2012 to 31 December 2015 were included. The annual reports of the scientific institute of the AOK, the biggest statutory health insurance in Germany, were used as data basis. The types of antibiotics, the number of prescriptions and the prescribed defined daily doses (DDD) were analyzed. The results were compared to antibiotic prescriptions of German physicians and to data of international studies.

Results: During the period of investigation an average of 8.8% per year of all antibiotic prescriptions is issued by dentists. Between 2012 and 2015 the dental share on all antibiotics fell by 12.1% (p<0.05). The most prescribed antibiotic is amoxicillin, the share of which on all dental prescriptions increased from 35.6% in 2012 to 45.8% in 2015 (p<0.01). About three-quarters of all dentally prescribed DDD can be attributed to amoxicillin and clindamycin. On the part of the German physicians and compared to international studies the structure of the prescriptions is much more heterogeneous.

Conclusion: Dental and medical antibiotic prescriptions in Germany show statistically significant differences regarding the types and the shares of the prescribed antibiotics. In the context of international studies on dental prescribing behaviour the high proportion of clindamycin and the low share of metronidazole in Germany are noticeable.

Biography

Dr Angela Mulrooney took a run-down practice in the hood, at 28 years old, and turned it into a cutting-edge practice, referred to by other dentists for full-mouth reconstruction, I.V. sedation, and sleep apnea therapy. Unfortunately, she sustained a career-ending injury in 2013. Not wanting her experience to die with her, she now helps dentists everywhere succeed by passing on her blueprint to success, helping colleagues realize their full potential clinically and financially. Let her love of dentistry, business, and life inspire you to bring your best game to your career and patient care.


Abstract

Are you learning cutting edge, research-based skills and not using them? Are you buying the best technology on the market and letting it sit? We return from conferences excited about the difference we can make as dentists. Shortly after returning, much of the knowledge and technology go to waste because our patients seem to not want the best we have to offer. It is frustrating and can be a never-ending cycle … until now. I welcome you to The Missing Dimension: The Art of Patient Conversation. Conversation with patients about what you to offer is not natural to most dentists and often fails when we try. However, that doesn’t mean you can’t master it. Mastery of The Art of Patient Conversation will unlock your ability to have patients wanting the best you offer. It will allow you to use your highest level skills and advanced technology every day in your practice rather than on rare occasions. It will change how patients perceive you and how they promote you. If you are struggling, frustrated and disillusioned about practice because you aren’t able to be your best self, now is the time to unlock your potential and be able to put your best foot forward every day in practice.

Post-graduate at the Oral and Maxillofacial Department of the Guy‘s and St. Thomas Hospital, London, UK. He is enrolled in the General Dental Council of London Member of the European Association for Osseointegration. Fellow Membership, Royal Society of Medicine, London, UK. Honorary Member of Oral Surgery Academy, London UK. He devised a new Zygomatic Minimally Invasive Technique associated with Piezoelectric Surgery. Winner for Best Oral Presentation: “ The treatment of atrophic maxilla using zygomatic implants “ Advances in Maxillofacial Implantology “, The Royal Society of Medicine, London, Uk. Fellow Research Oral Surgery Department - Pisa University - Dir. Prof. M. Gabriele. Currently, he published his first book entitled “ Gli impianti zigomatici: attualita’ nelle riabilitazioni implanto-protesiche dei mascellari atrofici “ by Quintessenza Editor. Mr Tedesco is a specialist Oral Surgeon and is an expert in Zygomatic Implant Dentistry and has recently published a book on this topic “Gli impianti zigomatici: attualita’ nelle riabilitazioni implanto-protesiche dei mascellari atrofici”. He’s recently devised a new minimally invasive technique for the use of zygomatic implants associated with Piezoelectric Surgery.


Abstract

Background: The zygomatic implants represent a valid alternative to regenerative surgery of severe maxillary atrophies. With a right clinical indication and a correct training for the operator, it is possible to treat complex cases with immediate loading to reduce the patient's discomfort. Actually, the classic technique with burs and intra-sinusal approach is very destructive way. The minimally invasive technique developed by the author with ESACROM, Imola, Italy, using piezoelectric dedicated inserts, helps the surgeon to realize an easy surgery, less demolishing, more predictable because the osteotomy preparation is always outside the sinus, totally with use of piezoelectric instrumentation.

Aim & Introduction: The zygomatic implants increase the quality of life and can be considered as the treatment of choice for the totally edentulous patient suffering from atrophic jaws. Usually, the zygomatic implant site preparation is still performed with long drills difficult to control. In addition, the classic intrasinus approach involves the maxillary sinus, increasing the morbidity, the operating times, and other complications difficult to resolve. The aim of this work is to evaluate a new minimally invasive technique using piezoelectric dedicated inserts and extra-sinusal approach.

Material & Methods: A total of 62 conventional implants were placed together with 53 zygomatic implants. The patients, 17 male and 9 female, no smokers, in good health, with a removable prosthesis, were followed up 24 months. After CT cone beam and software planning design, each surgery was performed placing for each patient two or four straight implants in the frontal area and two zygomatic implants in the zygomatic bone. Some cases have been treated with 4 zygomatic implants. Only one surgery was performed placing an oncology zygomatic implant. After planning the surgery a stereolithographic model was created for each patient. The insertion torque was over 35 Nc. The surgeries were performed under general anesthesia.

Results: No zygomatic implant was lost during the observation period. The survival rate for the zygomatic implants was 100% over an average of 24 months observation period. Two conventional implants were lost and there were no significant complications.

Discussion: The zygomatic implants are a valid alternative to grafting procedure for the rehabilitation of the atrophic maxilla, in many cases using an immediate function protocols. The zygomatic implants were placed outside the sinus and anchored in the maxillary alveolar process and in the zygomatic cortical bone.

Conclusion: Extrasinusal approach: no sinus complication. Piezoelectric strumentation (ESACROM, Imola, Italy)

Nobuko Kashiwai has completed her Master degree in Oral Science from Tohoku University in 2011 and belongs to the same university as PhD student. She is the CEO of HAG Creation Ltd., and to educate the importance of infection control for dental implant treatment to dentists and dental hygienists. She has published more than four papers in journals organized by some academic societies.      


Abstract

Intra and extra oral infection control is a key factor for the successful implant treatment. Pre-operative prevention of infection is required for an achievement of osseointegration, including general health control from systematic diseases, for instance, diabetes mellitus. The symptom of periodontitis should be treated before implant placement to prevent transient bacillaemia and peri-implantitis. For preventing the operator and assistants from the transmission of infectious diseases, it is also important to avoid the blood exposure during the surgical procedure. However, little is known about the severity and extent of blood contamination on surgical tools and personal protective equipments (PPE) for assistants during the surgery, such risk and the solution will be described during this presentation. And for post-operative prevention of infection, cleaning and sterilization of instruments and equipments are very important because most of them are not disposable. All bloody contamination should be cleaned completely to prevent an allergic reaction with the difference of DNA. Human has much normal bacterial flora in the oral cavity, but how to create the predictable and long-term success of implant treatment is up to the management of biofilm and prevention of inflammation occurred with infection. Infection control is very important but on the other hands, the establishment of reports between patients and dental faculties makes continuous supportive periodontal treatment as a goal.

Abstract

Natural fibres such as Hibiscus sabdariffa have become popular in reinforcing polymers due to their high toughness and strength. The low specific gravity, low abrasion, nontoxicity, renewability, availability, and environmentally friendly characteristics have promoted its use in the reinforcement of polymers. Despite Hibiscus sabdariffa being versatile and abundant, there is limited evidence of its use in Dental Technology, specifically in the reinforcement of denture base acrylics. This paper examines the hardness and wear resistance of Hibiscus sabdariffa fibre reinforced poly (methyl methacrylate) (PMMA) denture bases. An experimental research design within a quantitative framework was used. Two sample groups of PMMA specimens were prepared namely, the control (without fibres) and the test (7.5 weight% fibres). There were 27 PMMA specimens in each sample group. The surface hardness of the PMMA specimens (n=17 per group) were measured using a Barcol Impressor (Model GYZJ-934-1 from Barber-Colman Company). The specific wear rate was measured using a pin-on-disc set-up under ambient conditions at 200 g (n=5 per group) and 500 g (n=5 per group) fixed loads with a speed of 300 rpm for 60 seconds. Analysis of the results was obtained using a one-way ANOVA, an independent t-test and Mann Whitney test (p<0.05). While there were no significant differences in the hardness value (p<0.707) and the specific wear rate at 200 g load (p<0.156), the specific wear rate at 500 g load (p<0.044) between the two sample groups were significantly different. Results showed that mercerizing and pre-impregnating Hibiscus sabdariffa fibres potentially improves the wear resistance of PMMA denture bases, however, not the overall hardness. Using natural fibres to improve the mechanical properties of PMMA denture bases aligns with South Africa’s national development plan, specifically in terms of using natural resources to promote a greener and sustainable environment.

Abstract

Background & Aim: Since the high prevalence, worldwide, of periodontitis and peri-implantitis, both proven to contribute and/or exacerbate systemic diseases by their inflammatory response, they are becoming a major concern in general health care. The search for finding a cost-effective and repeatable treatment for the majority of the population, without causing detrimental side effects, are a necessity and has been a question mark for many years. Since traditional treatment protocols cannot meet to all our expectations and have some contraindications, the rational of one stage full mouth disinfection (OFMD) has been the new paradigm in treatment strategy. However, a number of important details can be optimized. Lasers have taken an eminent place in periodontal care in the last two decades. The use of free running pulsed (FRP) lasers in particular, might solve some shortcomings in the traditional approach. The reason behind this is the way FRP lasers, by their very short bursts of energy, cannot only take care of bacterial and viral components of the periodontal infection, in hard as well as in soft tissue, but also by dissipation of that energy, have the capability to contribute to repair and at certain level regeneration. This can contribute to the preservation of soft and hard tissue, in a cost-effective way.

Materials & Methods: Fifty-three patients having dpsi3+ or 4, undergoing all the same protocol of a true OFMD of scaling with the adjunct of FRP laser treatment, with or without antibacterial support as indicated along microbiological assessment. Periodontal parameters were compared to baseline, at 2, 8 up to 14 months, without retreatment. Clinical outcome of the parameters for all cases was statistically significant improved to baseline.

Abstract

The fundamental aim of dentistry is to maintain healthy natural dentition, while the main goal of endodontic treatment is to preserve functional teeth. During the endodontic treatment the pulp tissue, bacteria and bacterial products are removed. Endodontic treatment is complex procedure and for success, we have to follow strict protocol: accurate diagnosis, access cavity preparation, shaping and irrigation – chemomechanical preparation, obturation and final restoration. Until recently, mechanical instrumentation was the most important part of endodontic treatment, but more than 35% of the root canal surface remained untouched by instrumentation. Furthermore, during the instrumentation dentin debris and smear layer are produced. Biofilm, smear layer and dentin debris may be removed only by irrigation; therefore, different irrigation techniques (manual and mechanical) have been developed. One of the latest is LAI (laser-activated irrigation). The laser can be used in two ways: (1) directly, by irradiating the dentinal wall (CLE-conventional laser endodonty), or (2) indirectly, by irradiating/activating photoactive substances (PAD – photo activated disinfection) or irrigants (LAIs.l.). Erbium laser family presents one of the newer technologies in endodontics for activation of irrigants. The basic principle of LAI is producing the bubble that leads in three-dimensional flow of irrigants. According to the fiber/tip position in root canal system the latter is further divided into LAIs. and PIPS (photo induced photoacoustic streaming). Compared to other techniques, PIPS is very well defined by protocol of irrigation that includes laser parameters, tips, tip position, and propose the final sequence for irrigants with concentrations, supported by research results.

Biography

Pablo Esteban Castán has studied Odontology in European University of Madrid. He completed his studies doing differents Clincial Residents in Spain and in EEUU. Eight years ago he and his work team developed a technique to form new bone using allografts and mesenchymal stem cells. He has a private dental office focussed on Microsurgery and Oral Implantology in Zaragoza, Spain.


Abstract

Bone regeneration is one of the most useful technique to avoid early and future complications in oral implantology. Many times, the incorrect three-dimensional position of the implants is the reason why our treatments can fail, but we can avoid it having enough amount of bone support. In the literarture, almost every author agrees that the autologous bone is the “gold standard”, but there are some disadvantages in the use of it. When the lack of bone that we have to regenerate is big, the intraoral donor sites can not supply all the necessary amount, and we need to use other materials. Allografts are the most similar “scaffold” to autologous bone, and we supply the lack of cellularity doing a bone marrow aspiration to obtain messenquimal stem cells.

Abstract

Introduction: Diabetes adversely affects the morphology of the buccal mucosa and may compromise tissue function to favours the occurrence of oral infections and neoplasia. The morphologic and functional changes in oral mucosa can be studied at the cellular level by using exfoliative cytology which can help the diagnosis, with better patient acceptability as it is a painless, non-invasive and less time-consuming procedure.

Subjects & Methods: A total of 180 patients were included in the study. Patients were also grouped into the following three categories for further analysis based on their glycohemoglobin (GHb) levels: Controlled diabetics (CD) - GHb≤6%, Uncontrolled diabetics (UCD) - GHb>6% and ≤8% and Non-diabetics (ND) - GHb>8%. Smears were taken from clinically normal buccal mucosa of these subjects and stained to look for any abnormalities.

Results: Statistical analysis of the data obtained showed that the MV of Meisels cells from non-diabetic patients was significantly higher (p=0.008) than cells from diabetic subjects. Percentage of micronuclei was significantly higher (p=0.00) in uncontrolled diabetics as compared to controlled diabetics and non-diabetics.

Conclusion: Diabetes mellitus induces definite morphological and morphometric changes in the exfoliated buccal mucosal cells. However, for establishing exfoliative cytology as a diagnostic tool for diabetes, further studies are required on a larger scale.

Abstract

Despite the advances in prosthetic dentistry, the clinical steps of optimizing teeth contacts remains challenging for many dentists. The wellbeing of teeth, their supporting structures and the musculoskeletal complex are closely related to the occlusion stability. Dental occlusion is something far beyond the mere contact of the surfaces of teeth or prostheses; a fact that turned the subject of occlusion into a seemingly complex subject both to understand and to practice. The meticulous gnathological approaches described in the literature made the practice of occlusal treatments even more intimidating. Transcripting the biomechanics of jaw and teeth movements makes the goals of occlusal rehabilitation very clear and easy to implement. The purpose of this article is to draw a roadmap for understanding and implementing the core evidence-based occlusal principles in a simple, yet in-depth, way. This would provide a context for showing that occlusion is not as complicated as literatures might reflect. Possessing a clear perception of what a healthy occlusion should be like is very rewarding to both the diagnosis and the treatment process. The core occlusal concepts are simple to comprehend and easy to practice, with an added value of predictability, comfort, function and esthetics to the dental treatment.

Abstract

Twenty-two implants placed in four Taiwan patients to support immediate full-arch restorations (one mandible and three maxilla) with intact opposite dentition. Passive-fit metal-reinforced frameworks were fabricated chair side by intraoral welding method and all patients had definitive restorations on surgery day. All restorations were fabricated with implant-level components, screw-retained and inflicted full occlusal loading on the first day. Patients were recalled seven days, one month, three months and six months, with the follow-up period being over nine months until April 2016. All implants were osseointegrated, no infection was observed around the implants and no fracture or cracking was found on the restorations. All patients were satisfied with the restorations.

Tristan Staas graduated from the University of Utrecht in the Netherlands in 1988. Together with his wife who is also a dentist, they founded Staas and Bergmans Zorgvooruwmond in 1990, a praxis for general dentistry, and clinic for aesthetic dentistry and implantology in ’s-Hertogenbosch, Netherlands. In 2012 they founded a second office, Staas and Bergmans Expertisevooruwmond, a partnership clinic consisting of various dental specialists working as a team treating patients needing complex therapy. He has focused his practice and teaching interests on immediate implant placement in the aesthetic zone and collaborates with other clinicians working together in their practices in the Netherlands. He provides instruction to colleagues on immediate replacements, aesthetic solutions and the use of 3D technics, and is performing research on these procedures and long-term outcomes.


Abstract

This retrospective study aimed to analyse the fate of the buccal crest after immediate implant placement (IIP) through the use of cone beam computed tomography (CBCT). In 16 consecutive patients, an implant was placed in a more palatal position after extraction, thereby creating a gap of at least 2 mm between the implant and the buccal crest. Subsequently, this gap was filled with a bone substitute. Preoperatively, immediate postoperatively, and late postoperatively, a CBCT was made to measure the thickness of the buccal crest. After application of the bone substitute, the buccal crest increased in thickness from 0.9 mm to 2.4 mm (mean). At a mean of 103 weeks after IIP, late postoperative CBCT scans showed that the thickness of the buccal crest was compacted to 1.8 mm. In the same period, the height of the buccal crest increased by 1.6 mm (mean) to, on average, 1.2 mm above the implant shoulder. The aesthetic outcome was analysed using the White and Pink Esthetic Score (WES and PES). Both scored high: 8.4 and 11.8, respectively. Within the limitations of this study, the results of this IIP protocol are promising.

Abstract

Background: Clinical problems of the temporomandibular joint (TMJ) and the masticatory musculature are both included in the term temporomandibular disorder (TMD). The field of TMD is well known for being one of the more controversial topics in dentistry. Studies show a marked difference in the prevalence of TMD from 16 to 64%. The purpose of the present study was to examine whether patients with clinical TMD had pathological findings utilizing magnetic resonance imaging (MRI).

Material & Methods: The study population consisted of 64 patients with clinical TMD. Symptoms were recorded using a questionnaire, clinical examination included diagnosing occlusion in centric relation, and then a standardized MRI was performed. The images were read, utilizing the Piper system by the treating dentist and then read by two experienced radiologists blinded to clinical data.

 

Results: All patients had molar interferences in centric occlusion and limited anterior guidance. The patients also had changes in disc position when examining the MRI scans. 68 of the joints (55%) had changes corresponding to Piper IVa classification. It was also found more severe changes like disc degeneration, changes in condylar head, abnormal reduction and restriction in anterior movement. The most severe changes were corresponding to Piper Va and Vb (34 joints, 27%).

Conclusion: All the patients assessed due to TMD showed changes in their TMJ on MRI. We also found posterior interferences in their occlusion and loss of anterior guidance.

Stanley C Onwubu has graduated his Master’s degree at the Durban University of Technology cum laude in 2016. He is currently in his third year studying towards his PhD at the Durban University of Technology. He has published articles and book chapters in reputed journals. He strongly has a passion for the development of new dental materials from recycled materials. He has previously worked on new abrasive materials using waste eggshells for polishing polymethyl methacrylate resin dentures. His current doctoral research focuses on remineralization of damaged teeth using nano-sized titanium dioxide modified eggshell powder with a view of developing a mathematical model to predict dentine remineralization. 


Abstract

Objective: This paper reports on the buffering and acid-resistant properties of a modified eggshell-titanium composite against erosive acids.

 

Materials & Methods: Eggshell-titanium EB-TiO2 was prepared by ball milling eggshell powder and titanium dioxide. Fourier transform infrared spectroscopy (FTIR), x-ray diffraction (XRD), transmission electron microscopy (TEM), were used to characterize EB-TiO2. The buffering property against lactic and citric acid at pH 2, 4, and 5 was measured using pH meter. Five brands of toothpaste (Colgate, Colgate Sensitive, Aquafresh, Oralwise, and Sensodyne) were used to assess the acid-resistant properties of EB-TiO2. Enamel models were simulated by dissolving each brand of toothpaste with eggshell (control) and EB-TiO2. The samples were exposed to citric and lactic acid of pH 2. The average slope (kPa/s) was measured using a pressure sensor. ANOVA was used to analyze the kPa/s values (α =0.05).

 

Results: The FTIR, XRD analysis suggests the surface modification of EB-TiO2. The TEM image revealed nonhomogeneous shaped particles with an average size of 13 nm. The pH test results showed that the buffering properties of eggshell and EB-TiO2 were comparable. Significant differences were observed in the acid resistance properties of the samples exposed to both citric and lactic acids (P<0.05). The Colgate toothpaste infused with eggshell powder had the highest mean kPa/s values, whereas EB-TiO2 had the lowest kPa/s values.

 

Conclusion: The salient features of this study indicate that modification of eggshell with titanium dioxide does not affect its carbonate buffering properties. Connecting the kPa/s values to acid resistant properties, EB-TiO2 effectively reduces erosive attacks when added to toothpaste

Abstract

Peri-implant diseases present in two forms – peri-implant mucositis and peri-implantitis. Both diseases are characterized by an inflammatory reaction in the tissues surrounding an implant. Studies have estimated that peri-implant mucositis has a prevalence ranging from 50% to 80%, while peri-implantitis affects approximately 12%-40% of implants and 28%-56% of patients, respectively. In addition, it was evident that the lack of annual supportive therapy in patients diagnosed with peri-implant mucositis is associated with increased risk for conversion of mucositis to peri-implantitis. Therefore, early detection of peri-implant breakdown, as well as monitoring progression of bone loss is extremely important. The aim of this study is to present the clinical protocol for peri-implant diseases supportive therapy, the clinical experience based on science.  How could the diagnosis be refined and specific in dental practice?  How to predict failures? What can we do to improve the future and minimize peri-implant diseases rates?

Abstract

Despite the high success rate of non-surgical root canal treatment of permanent teeth in caries-exposed pulp, the procedure is more complicated and expensive. Moreover, the longevity of root-treated teeth is lesser than teeth with sound pulp. Complete pulpotomy is vital pulp therapy procedure in which the coronal inflamed pulp tissues are removed while radicular tissues are preserved. The procedure usually recommended for immature teeth with reversible pulpitis. The radicular pulp is preserved in order to ensure the continued root formation. The advent of new calcium-silicate materials like MTA made the paradigm shift in the field of endodontic and vital and regenerative pulp therapy procedures. These materials are found to be promoting/inducing the pulp healing and regenerative potential of pulp. In current research papers, these materials have been used for either partial or complete pulpotomy in caries-exposed mature permanent teeth with a favourable outcome. In our study which was performed at the Liaquat University of Medical & Health Sciences, Jamshoro, Pakistan twenty mature permanent teeth with irreversible pulpitis treated by complete pulpotomy procedure with calcium-silicate based materials. So, in this paper, we will highlight the outcome of our study and factors which determine the success of pulpotomy procedure in conjunction with clinical technique.

Abstract

This in-vitro study investigated effect of different gamma radiation doses on the mechanical properties of esthetic restorations. A total of 84 standardized specimens were prepared for this study. Each 21 of them were prepared using the following four resin composites: Ceram X (Dentsply), Z350 xt (3M ESPE), Xtra fill (Voco) and Grandio (Voco). Then, the 21 specimens were divided as follows: 3 specimens representing the control group (C) were cured using woodpecker LED light cure unit, 9 specimens were subjected to gamma radiation after curing (IaC) from which three were subjected with a dose of 10 Gy (IaC-10), the other three with 30Gy (IaC-30) and the last three with 60 Gy (IaC-60); the last 9 specimens were subjected to gamma radiation before curing (IbC) from which three were subjected with a dose of 10 Gy (IbC-10), the other three with 30 Gy (IbC-30) and the last three with 60 Gy (IbC-60). All specimens were subjected to measurement of surface microhardness in Vickers hardness tester. The depth of cure was calculated by obtaining the microhardness ratio through dividing Vickers hardness number (VHN) of the bottom surface by VHN of the top surface. Data was then recorded, tabulated and statistically analyzed. Most results of the specimens’ top showed a statistically significant increase in mean microhardness of IaC and IbC sub-groups in relevance to the control groups. Most results of the specimens’ top showed a statistically significant increase in mean microhardness of IbC sub-group in relevance to IaC sub-group. Results of (B/T) showed an increase in mean depth of cure of IbC sub-groups in relevance to the control group and to IaC sub-groups, where most of them are statistically significant. Pearson correlation coefficient between top and bottom was found to be statistically significant (r=0.9). In conclusion, surface micro hardness of different composite resin has improved following being subjected to gamma radiation by various doses, on the other hand, most of the results of the depth of cure were low for the group IaC and have improved for the group IbC.

Abstract

Background: E-cigarette smoking is becoming a fast-growing trend amongst the young adults today. The practice of young adults smoking E-cigarettes may have been adopted as a way of smoking cessation or just to follow a trend. However, most people still remain unaware of the detrimental effects of smoking E-cigarettes. The present study was carried out to assess the prevalence of the habit of smoking E-cigarettes and the awareness of the harmful effects of the same amongst adults aged 18-23 years.

Methods: A questionnaire adopted and modified for using Google forms from Farsalinos K E et al. was used in the study. Participants were requested to fill the survey irrespective of their smoking status after taking consent.

Results: The cohort had 710 samples from 6 countries, with the mean age of 20.65±1.701 years. There were 412 females and 298 males in the study. Most of the respondents were from India, the second most common participants were from the USA followed by the UK. The most common mode of information on the existence of E-cigarettes to the participants was from family members, friends followed by the internet search engines and TV/ newspaper advertisements. E-Cigarettes had a prevalence of 5.63% among the cohort (40/710). Among these, 26 participants have been using E-cigarettes for less than 1 year and 2 participants for more than 5 years. E-cigarette smokers also experienced sore throat, cough, headache, dizziness and sleeplessness. Less than half of the young adults were unaware of the amount of nicotine in the E-liquid.

Conclusion: Majority of the young population was unaware of the use and harmful effects of E-cigarette. Attempts should be made to spread awareness using media campaigns, educational videos and online surveys.
