Abstract
Preservation of teeth until old ages indicates oral health status. 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.

Summary
Poor oral hygiene was highlighted as a serious public health problem in 2010 WHO report about “equity, social determinants and public health programs” [1]. Life expectancy is one of the most important measures that are improved in developing countries nowadays, so quality of life improvement is one of the most interesting topics of policymakers. Life expectancy improvement has been made teeth care an important topic, as it is shown that this index will be higher in countries with people having more teeth, and tooth preservation was accompanied by higher quality of life [3] [4]. According to impressive improvement in dental treatment, preservation of permanent teeth until old ages is not unachievable, and TE is just considered as a final treatment. Preservation of tooth and its supporting tissue until old ages indicates both oral health level and health system efficacy. Some patients are not available to repair decayed teeth just because of financial issues, which show patients need to health system supports [9]
