“…Sadeghi also reported a CF prevalence of 30.4% in a study in 2006 on students of 11-12 years of age in Rafsanjan (4). The health status of the first permanent molar is a disease-centered index related to dental caries and a suitable dental health index for children and adults (9). The first permanent molar was introduced as an index for the prediction of caries activity, determination of dental and oral health status, and determination of groups most vulnerable to caries by the World Health Organization (WHO) in 1994 (1,10).…”

Received: February 2017, Accepted: May 2017 Background: Dental caries is the most prevalent oral disease among children. The first permanent molar has been introduced as an index for predicting caries activity, and determining dental and oral health status and the groups most vulnerable to caries. Thus, the aim of this study was to determine the prevalence of caries in the first permanent molars among students of 7 and 12 years of age in Rafsanjan, Iran, in 2009-2010. Materials and Methods: This cross-sectional study was conducted on 360 students (girls and boys) in Rafsanjan. The participants were selected through multistage random sampling. Clinical examination for the diagnosis of caries was based on the World Health Organization (WHO) criteria. Data were collected through interviews and clinical examinations and analyzed using Mann-Whitney and chi-square tests. Results: The total mean decayed, missing, and filled teeth (DMFT) index of the sample was 1.66 ± 1.47 (1.78 ± 1.51 in boys and 1.51 ± 1.42 in girls) (P = 0.081). Mean DMFT was 1.79 ± 1.33 and 1.52 ± 1.56 in the 12 years and 7 years age groups, respectively (P = 0.029). The decayed teeth (DT), missing teeth (MT), and filled teeth (FT) in this index were 52.21%, 40.96%, 6.82%, respectively. The prevalence of caries free (CF) among the students was 34.7% (31.28% in boys and 37.57% in girls). A statistically significant difference was observed among the students in terms of gender and age (P < 0.05); CF was 43.24% in the 7 years age group and 24.57% in the 12 years age group. Conclusions: Considering the WHO criteria, the prevalence of caries and CF in the first permanent molars among students of 7 and 12 years of age in Rafsanjan was relatively favorable.

ObjectivesThis study aimed to analyse the 2010–2018 cohort data of the National Health Insurance Service to examine the association between applying sealants in the first molars of children and their early dental impairment.MethodsBased on the two‐level mixed effect model (individual four teeth), the study participants were divided into two groups: those with sealants on all four first molars and those without sealants to determine the association between sealants and early impairment. We analysed teeth that had undergone extraction or canal filling to determine early impairment.ResultsThe rate of early impairment in the first molars was approximately 7.4 times lower in the sealant group (0.65%) than in the non‐sealant group (4.83%). Early impairment of first molars was higher in females, medically cared for and in rural populations. It was also higher in the maxillary first molars (3.7%) than in the mandibular first molars (3.49%), in more rural areas, and in lower household income groups. In generalised linear mixed models, first molars with sealants were 14.9% less likely to have early impairment than those without sealants (p = 0.000).ConclusionsThe study findings suggest that applying sealants on the first molars is important to prevent early dental caries development and prolong the functional integrity of first molars. In addition, we found that maxillary first molars were more susceptible to early impairment than mandibular first molars, even when sealant was applied.
