In this study, we analyzed the prevalence of carious lesions using a standardized evaluation system, while following the analysis of the influence of favoring factors represented by the type and frequency of snacks and the frequency of tooth brushing. Method: A clinical\u2013statistical study was carried out on a group of 311 children from both urban and rural environments, aged between 6 and 19 years old. As a diagnostic system and assessment of the depth of carious processes, we used the ICDAS system. The following parameters were recorded: odontal status of the 4 FPMs, age, gender, residence, frequency of dental brushing, and frequency of between-meal snacks and their type. The ICDAS system was used as a diagnostic system and assessment of the depth of carious processes. The data were statistically analyzed with SPSS, using the Kruskal\u2013Wallis H and Chi-Square tests. Results: The occlusal surface was the most interesting in the presence of odontal lesions. Sweet snacks were the most frequent snacks consumed by the subjects. The age group of 13\u201319 years presented fewer healthy FPMs, compared to the age group of 6\u201312 years. The higher involvement of older subjects was found for all four molars, both in the case of identified carious lesions and the presence of root debris and edentations. Brushing twice a day was more frequent in the 6\u201312 age group. In analyzing the status of the first molars in relation to the gender of the subjects, in the present study, no statistically significant differences were recorded between the status of the molars relative to gender, except for molar 1.6 (p &gt; 0.05). Regarding the other types of snacks, children from rural areas consume more fruits than those from urban areas. Conclusions: The frequency of tooth brushing and the type and frequency of snacks between meals influence the prevalence of carious lesions at the level of the first permanent molars.<\/jats:p>","DOI":"10.3390\/jcm14030669","type":"journal-article","created":{"date-parts":[[2025,1,21]],"date-time":"2025-01-21T05:47:42Z","timestamp":1737438462000},"page":"669","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Clinical Statistical Study on the Prevalence of Carious Lesions in First Permanent Molars"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6535-3152","authenticated-orcid":false,"given":"Mihaela Jana","family":"\u021auculin\u0103","sequence":"first","affiliation":[{"name":"Department of Endodontics, Faculty of Dentistry, University of Medicine and Pharmacy of Craiova, 200349 Craiova, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andreea Mariana","family":"B\u0103n\u0103\u021beanu","sequence":"additional","affiliation":[{"name":"Department of Prosthodontics, Faculty of Dental Medicine, University Titu Maiorescu of Bucharest, 67A Gheorghe Petrascu Str., 031593 Bucharest, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0865-9083","authenticated-orcid":false,"given":"Adela Nicoleta","family":"Staicu","sequence":"additional","affiliation":[{"name":"Department of Endodontics, Faculty of Dentistry, University of Medicine and Pharmacy of Craiova, 200349 Craiova, Romania"},{"name":"Doctoral School, University of Medicine and Pharmacy of Craiova, 200349 Craiova, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3210-1212","authenticated-orcid":false,"given":"Alexandru Dan","family":"Popescu","sequence":"additional","affiliation":[{"name":"Department of Endodontics, Faculty of Dentistry, University of Medicine and Pharmacy of Craiova, 200349 Craiova, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-6707-7882","authenticated-orcid":false,"given":"Jaqueline","family":"Abdul-Razzak","sequence":"additional","affiliation":[{"name":"Doctoral School, University of Medicine and Pharmacy of Craiova, 200349 Craiova, Romania"},{"name":"Department of Infant Care\u2013Pediatrics\u2013Neonatology, University of Medicine and Pharmacy of Craiova, 200349 Craiova, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ionela Teodora","family":"Dasc\u0103lu","sequence":"additional","affiliation":[{"name":"Department of Orthodontics, Faculty of Dental Medicine, University of Medicine and Pharmacy of Craiova, 200349 Craiova, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cristian Levente","family":"Giuroiu","sequence":"additional","affiliation":[{"name":"Department of Endodontics, Faculty of Dentistry, University of Medicine and Pharmacy Grigore T Popa Iasi, 700115 Iasi, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Veronica","family":"Mercu\u021b","sequence":"additional","affiliation":[{"name":"Department of Prosthodontics, Faculty of Dental Medicine, University of Medicine and Pharmacy of Craiova, 200349 Craiova, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Monica","family":"Scrieciu","sequence":"additional","affiliation":[{"name":"Department of Prosthodontics, Faculty of Dental Medicine, University of Medicine and Pharmacy of Craiova, 200349 Craiova, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4646-9993","authenticated-orcid":false,"given":"Oana","family":"Amza","sequence":"additional","affiliation":[{"name":"Department of Endodontics, Faculty of Dentistry, University of Medicine and Pharmacy Carol Davila Bucharest, 050474 Bucharest, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mihaela","family":"Ionescu","sequence":"additional","affiliation":[{"name":"Department of Medical Informatics and Biostatistics, Faculty of Dental Medicine, University of Medicine and Pharmacy of Craiova, 200349 Craiova, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"22","DOI":"10.1186\/s13005-020-00237-z","article-title":"Dental caries in primary and permanent teeth in children\u2019s worldwide, 1995 to 2019: A systematic review and meta-analysis","volume":"16","author":"Kazeminia","year":"2020","journal-title":"Head Face Med."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"94","DOI":"10.1111\/jcpe.12677","article-title":"Global epidemiology of dental caries and severe periodontitis\u2013a comprehensive review","volume":"44","author":"Frencken","year":"2017","journal-title":"J.
