Association between normative and self-perceived orthodontic treatment need in a Lebanese population.

The aims of this study were to investigate the association between normative and perceived orthodontic treatment need in a Lebanese population and the effect of sociodemographic status on orthodontic treatment need. A prospective cross-sectional clinical study was designed using a sample of 150 subjects (81 males and 69 females) aged 11-18years seeking dental treatment at Beirut Arab University. Normative orthodontic treatment need was scored using the two components of the Index of Orthodontic Treatment Need (IOTN), the Dental Health Component (DHC) and the Aesthetic Component (AC). Perceived need for orthodontic treatment was evaluated by scoring the AC of the IOTN. A total of 31.3% of the sample were in great need of orthodontic treatment according to the DHC of the IOTN. On the other hand, only 9% of the sample perceived their need to be definite. A significant positive but weak correlation was found between the normative and perceived need for orthodontic treatment. There was also a significant association between age and normative treatment need.

Opinions of dental students toward tobacco cessation intervention in the United Arab Emirates.

OBJECTIVE: The objective of this study was to investigate the opinions of dental students, in one of the dental colleges in the United Arab Emirates (UAE), toward providing tobacco cessation interventions to their patients. MATERIALS AND METHODS: Three-hundred-and-fifty students were administered a questionnaire including questions about tobacco cessation interventions (with a response rate of 77%). We generated descriptive statistics for all questions and examined the frequency distribution and percentages of all answers. Data were analysed using cross-tabulations and χ(2) -tests. The statistical significance was set at P < 0.05. RESULTS: While 83.4% of students agreed that dentists should be trained in tobacco cessation, 56% of students disagreed that they are adequately trained to assist the patient in stopping tobacco use. As the year of study increased, the students' 'agree' responses increased to the statements that the dentist should be trained and that the dentist has a role in assisting patients to stop smoking. Non-Arab students were more confident than Emiratis in tobacco cessation counselling. The percentage of female students who felt greatly confident in assisting was double that of male students. There was a significant difference between tobacco-user students and non-users in response to the question about dentist's role in assisting tobacco cessation. CONCLUSION: A comprehensive tobacco cessation education and training program should be included in dental schools' curriculum in the UAE to further improve student confidence in providing tobacco cessation services to their patients.

Comparative antiplaque and antigingivitis effectiveness of tea tree oil mouthwash and a cetylpyridinium chloride mouthwash: A randomized controlled crossover study.

OBJECTIVE: The aim of this study was to compare the antiplaque and antigingivitis effects of a mouthwash containing tea tree oil (TTO) with a cetylpyridinium chloride (CPC) mouthwash. MATERIALS AND METHODS: This was a randomized 4 × 4, controlled, cross-over, involving 20 healthy volunteers in a 5-day plaque re-growth model. Test mouthwashes were TTO (Tebodont(®)) and a mouthwash containing CPC 0.05% (Aquafresh(®)). A 0.12% chlorhexidine (CHX) mouthwash (Oro-Clense(®)) was used as positive and colored water (placebo [PLB]) as negative controls. Gingival bleeding index (GBI) and plaque index (PI) scores were recorded before and after each test period. Test periods were separated with 2 weeks washout period. RESULTS: All four mouthwashes significantly (P < 0.001) reduced the GBI scores when compared to the baseline GBI scores. There was no significant difference between PLB and active mouthwashes in the GBI scores. CHX and CPC mouthwashes were found more effective in reducing the PI scores than TTO and PLB mouthwashes. There was no significant difference in PI scores of CHX and CPC mouthwashes. CONCLUSION: 0.05% CPC mouthwash can be an alternative to CHX mouthwash since it is alcohol free and found as efficient as CHX in dental plaque reduction with lesser side effects. More studies are needed to test antigingivitis effects of the mouthwashes used in this study, preferably without initial scaling and polishing.

Assessing dental students' knowledge of oral cancer in the United Arab Emirates.

OBJECTIVE: The purpose of this study was to assess the knowledge of future dentists of the United Arab Emirates on risk and non-risk factors for oral cancers and correlate it with their own tobacco use, whether they assess their patients' tobacco use and their opinion about the relation of oral cancer and smokeless tobacco use. METHODS: A total of 270, first- to fifth-year undergraduate dental students who consented to participate in the study filled in a questionnaire enquiring about their knowledge of oral cancer risk factors. A score of oral cancer risk factor knowledge was calculated for each participant based on their correct answers. RESULTS: Eighty-three per cent of participants identified the use of tobacco as a risk factor for oral cancer, 52% identified old age, 45.6% knew about low consumption of fruits and vegetables and 74.4% of students could correctly identify use of alcohol as a risk factor for oral cancer. A significant association was found between being a current and previous tobacco user and having low knowledge of risk factors score (P = 0.015). No significant associations were found between the year of study in the dental college, gender, nationality and knowledge of oral cancer risk factor scores. CONCLUSION: This study showed an apparent lack of knowledge of oral cancer risk factors among dental students that may later result in a deficiency in integrating optimal oral cancer diagnostic procedures in their practices. There is an urgent need to enhance the oral cancer curricula in oral cancer education and clinical training in oral cancer prevention and examination for dental students.
