Improving life expectancy in developing countries makes teeth care an important topic. This study assessed reasons of tooth extraction (TE), oral health determinants and demographic factors of permanent TE in Iranian adults. Adult people who referred to dental clinic of Mashhad Medical University in 2012 for dental extraction and lived in Mashhad city, participated in this study by convenient sampling method after obtaining informed consent. Demographic characteristics, oral health status, health habit and reasons of TE of participants were assessed. Data were analyzed by SPSS11.5 by Chi-Square, T-Test, ANOVA, Mann-Whitney and Kruskall-Wallis tests. Totally 254 people participated (383 extracted teeth) that 55% were female. Mean age of participants was 39.3 years;females were 6.1 years younger than males. The main reason of TE was dental caries (55.1%), following by impaction. There was significant difference between average times of tooth brushing in both sexes, but difference was not shown in sugar intake. Except in people with college degrees that dental caries is the main cause of TE. With increase in life expectancy to more than 70 years old in Iranian, the age of TE especially in women is younger than expected. The most common cause of TE is dental caries that seem in spite of improving health indexes in Iran, poor oral hygiene remains as a problem. There is no significant difference between frequency of sugar intake and level of education that indicates unhealthy dietary habits related to tooth decay.展开更多

The panoramic radiography was complemented by the Donovan＇s radiographic technique; but because of the proximity of the dental element to the mandibular ramus, it was not possible to have a final fusion diagnosis. Hence, the Cone-Beam Computed Tomography--which provides precise three- dimensional information--was used to determinate the fusion diagnosis and also to help in the surgical planning. In this case report we observed that the periapical, occlusal and panoramic were not able to show details which could only be examined through the cone-beam computed tomo- graphy.展开更多

Material and Methods: The BMI and DMFT of 202 cases, with an age average 22.5 years, were recorded through physical and clinical examinations. Statistical evaluation of the data was checked by Cronbach’s Alpha Reliability Scale and performed by analysis of variance, Somer’s d and Pearson Chi-Square statistics, Poisson Regression and Odds Ratio analysis. Results: The results showed that the mean of BMI was at the optimum level (21.52) for all cases. The DMFT was higher for underweight females and for overweight males. The mean of DMFT according to sexes seemingly had no significant difference;however, females had 8.6% more DMFT than males. When the risk factors of dental caries were evaluated, the DMFT was found as 19.3% more for cases consuming high carbohydrate foods, 4.5% more for high beverage consumption and 18% more for smokers. Conclusions: In conclusion, tooth brushing 3 or more times a day is necessary to decrease the DMFT and tooth brushing 3 times a day as opposed to 1 or 2 times shows significant difference regarding oral health.展开更多

The random-effects models were used to derive a pooled effect across studies. Potential sources of heterogeneity on the characteristics of the study and their influence on the pooled effect size were investigated using metaregression models. RESULTS: We identified 24 studies containing a total of 95973 participants for analysis. The pooled RR of ever-smokers compared with never- smokers was 1.73(95%CI: 1.60-1.86, P < 0.001). In meta-regression analysis, only the mean age of participants alone was identified as a statistically significant source of heterogeneity. The effect of smoking on tooth loss was stronger when the mean age of study participants was higher, indicating possible enhancement of tooth loss due to aging by smoking. RR was significantly lower in former smokers(1.49, 95%CI: 1.32-1.69, P < 0.001) than in current smokers(2.10, 95%CI: 1.87-2.35, P < 0.001), indicating the substantial benefit of smoking cessation for reducing the risk of tooth loss.CONCLUSION: Smoking is an independent risk factor for tooth loss regardless of many other confounders. Smoking cessation may attenuate this effect.展开更多
