Prevalence of Dental Caries of the First Permanent Molars among 6-14 Years Old Sudanese Children

Background and Objectives: Early detection of dental caries lesions at active stages of development can facilitate their monitoring and reduce needs for restorative dental care. This study aimed to describe the prevalence and caries treatment needs in first permanent molars of pre-school children, based on a caries lesion activity assessment, and in relation to participants’ ages, dental plaque levels and toothbrushing habits. Materials and Methods: Large cross-sectional dental caries survey using multistage cluster sampling was conducted among Lithuanian 4–6-year-old children attending kindergartens. For the present study purpose, all individuals presenting erupted permanent molars were selected. Thus, only 5–6-year-olds (n = 453) took part in this study. They were examined for caries by one calibrated examiner using Nyvad clinical diagnostic criteria that differentiate between active and inactive caries lesions. Dental plaque was assessed by the Silness-Löe index, and parents’ reports about toothbrushing frequency were collected. Results: Overall, 41% of permanent molars were affected by caries; 6-year-olds had more caries lesions than 5-year-olds (p < 0.05). Mean number of decayed and filled surfaces (DF-S) of all participants was 1.79 (SD 2.93), half of lesions were noncavitated, more than one-third were cavitated and fillings comprised less than one surface per child. Majority of lesions were active; prevalence of inactive lesions (all noncavitated) was 1% and 6% in 5- and 6-year-olds, respectively. Prevalence of active lesions increased with age; it correlated with plaque levels and with toothbrushing frequency (<0.001). Likelihood to detect active lesions was up to nine times higher in teeth with abundant plaque (odds ratio (OR) 8.73; confidence interval (CI) 5.35–14.25), and up to seven times higher in individuals brushing teeth irregularly (OR 6.88; CI 2.21–21.41). Conclusions: The obtained data indicate high treatment needs in the erupted permanent molars of the Lithuanian pre-school population and imply that caries management should primarily focus on improved biofilm removal, accompanied with regular use of fluoridated toothpaste.

This study aimed to evaluate the association between the fissure depth (tooth morphology) of permanent molars and dental caries incidence with a five-year follow-up period. In total, 110 Mexican schoolchildren aged seven years were recruited at baseline, of which 88 children completed the follow-up assessments. The fissure depths of the first permanent lower molars were recorded, and dental caries [decayed, missing, and filled deciduous surfaces (dmfs) and decayed, missing, and filled permanent surfaces (DMFS)] was evaluated annually. A generalized estimating equation model was constructed for evaluating the association between dental caries and fissure depth. The initial and final DMFS scores were 0.02 (±0.2) and 1.55 (±2.49), respectively. The generalized estimating equation model showed that children with deep molar fissures were more likely to develop caries lesions, (Odds Ratio OR = 3.15, p = 0.028) compared to children with shallow fissures. Moreover, dental caries in primary teeth (OR = 1.07, p = 0.005) was associated with the development of carious lesions in the permanent dentition. Fissure depth was a useful predictor of dental caries, according to this five-year follow-up study. The detection of deep occlusal fissures in the lower first permanent molars could contribute to the identification of children at high risk of dental caries. Tooth morphology may be used to identify children at a higher caries risk, particularly in settings with limited resources.

ABSTRACT Aim To evaluate the prevalence of molar incisor hypomineralization (MIH) and its relationship with dental caries in school children of Udupi district. Materials and methods A total of 352 school children were recruited for this study. The European Academy of Pediatric Dentistry (EAPD) 2003, criteria were followed for diagnosis of MIH. Dental caries was recorded using World Health Organization (WHO) guidelines (1997) under natural day light. Results The prevalence of MIH was seen to be 27% (n = 95). A total of 323 teeth had hypomineralization (106 were incisors and 217 were molars). The lower molars (n = 127) were more frequently affected than the upper molars (n = 90). Overall the maxillary incisors (n = 68) were more affected than the mandibular incisors (n = 38). Amongst the children with MIH, the mean number of decayed teeth was significantly lower than mean number of hypomineralized teeth in first permanent molars and first permanent molars and incisors (p < 0.001 and < 0.001) respectively. The mean decayed teeth in first permanent molar and incisors were significantly higher in subjects with MIH than without MIH (p < 0.001). Poisson regression analysis showed a significant positive association between MIH and dental caries (B = 1.43; p < 0.001). Conclusion The prevalence of MIH was relatively high and was associated with dental caries. How to cite this article Tadikonda AN, Acharya S, Pentapati KC.

Dental caries is one of the most common infectious diseases affecting 6–8-year-old children, especially their first permanent molars (FPMs). This study explored the prevalence of dental caries on FPMs by analyzing the oral health status of 1,423,720 children aged 6–8 years in Zhejiang Province, China. The data were extracted from the dental electronic records of the schoolchildren attending the Oral Health Promotion Project (OHPP), conducted during 2013–2017 in Zhejiang Province. Multiple logistic regression models were used to determine the factors affecting dental caries. Boys and girls accounted for 53.2% and 46.8% of the subjects, respectively. From 2013 to 2017, the prevalence of dental caries on FPMs increased: 2013: 20.4%; 2014: 25.3%; 2015: 24.5%; 2016: 27.0%; and 2017: 29.0%, despite the OHPP conducted. Based on multiple logistic regression model, girls had a significantly higher risk of FPM caries compared to boys (OR = 1.38, 95% CI: 1.37–1.39, p < 0.0001); compared with the caries rates in urban areas, the caries risk was significantly higher in rural areas (OR = 1.15, 95% CI: 1.14–1.16, p < 0.0001). In terms of geographic location in Zhejiang Province, the odds ratios of the caries risk of the east, south, west, and north were 1.35 (1.33–1.36), 1.3 (1.28–1.31), 0.81 (0.8–0.83), and 0.82 (0.81–0.84), respectively (p < 0.0001), by considering the central region as a reference. The caries prevalence of FPMs was high, with an increasing tendency and gender, social, cultural, and environmental factors affecting the caries prevalence.
