摘要

Background: From a purposeful and developmental purpose of view, the primarypermanent molars are the important teeth, with the key role in occlusion. The most rolesof first permanent molars are established in balanced occlusion. Loss of first permanentmolars, as a result of dental caries, negative affects each arch and has adverse effects onocclusion. The loss of a first permanent molar in an exceedingly child will causechanges within the dental arches which will be derived throughout the lifetime of thatperson. Objective: The purpose of this study is providing the basic approach to choosemanagement tools The aim of this study was to evaluate the treatment needs of firstpermanent molars in an exceedingly group of schoolchildren in Tehran. In October2012, as an epidemiological survey, this research was conducted with 526 third-gradeschool children who were learning in 16 primary schools of Tehran. The schools wereat random selected from every district. By a double-blind approach, treatment needsand DMFT of first permanent molars were calculated for first molars consistent withOral Health Surveys: All mentioned data together with hygiene habits and first molarsdental caries status was analyzed using SPSS statistical software. The importance wasset at P < 0.05. Results: The 97.9% of all school children had received the fluoridesolutionfor 3 years and 87.7% of the school children brushed a minimum of once on adaily basis however unfortunately, 91.63% of students didn't floss. The first-molarsoriented DMFT of this population was 0.6290± 1.0337 within the case of girls; the firstmolarDMFT was 0.7498+ 1.1187 whereas in boys it had been 0.5121± 0.8598. Inresult, the girls' dental caries rate was considerably additional than boys. (P<0.0009).Conclusion: High treatment needs and dental caries prevalence in permanent firstmolars in Tehran schoolchildren show that caries remains a very important problemwithin the children of our society; so, either in favor or against of caries-facilitating roleof oestrogene, an additional comprehensive study is critical to seek out the exact factorsinflicting higher frequency of female first-molar dental caries in primary school ages.
