Nolla\u2019s developmental stages may provide a more reliable guide for MF localization, potentially improving the success of Inferior Alveolar Nerve Block (IANB) in pediatric patients.<\/jats:p>\n <\/jats:sec>\n \n Aim:<\/jats:title>\n The aim of the study is to assess the association between the position of MF and Nolla\u2019s developmental stages of mandibular permanent first and second molars in children aged 6\u201315 years using Orthopantomographs (OPGs).<\/jats:p>\n <\/jats:sec>\n \n Materials and Methods:<\/jats:title>\n This cross-sectional study analyzed 255 OPGs of children aged 6\u2013-15 years. Bilateral MF depth relative to the deepest point of the coronoid notch and height relative to the mandibular occlusal plane were measured. Developmental stages of the mandibular permanent first and second molars were assessed using Nolla\u2019s developmental staging (0\u201310). Statistical analyses were performed.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n MF depth and height increased significantly with advancing Nolla\u2019s developmental stages bilaterally of the mandibular permanent first and second molars (\n P<\/jats:italic>\n = 0.004;\n P<\/jats:italic>\n < 0.001). Chronological age showed a significant but weak positive correlation with MF depth and height (\n P<\/jats:italic>\n < 0.001). No significant gender differences were observed in MF position (\n P<\/jats:italic>\n > 0.05). Significant bilateral differences were found in MF height (\n P<\/jats:italic>\n < 0.001).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n MF position correlates significantly with developmental stages of the mandibular permanent first and second molars, offering a more reliable reference than chronological age. This may improve accuracy and success of IANB anesthesia in children.<\/jats:p>\n <\/jats:sec>","DOI":"10.4103\/jisppd.jisppd_371_26","type":"journal-article","created":{"date-parts":[[2026,8,25]],"date-time":"2026-08-25T16:00:22Z","timestamp":1787673622000},"page":"411-416","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Association between mandibular foramen position and Nolla\u2019s developmental stages of mandibular permanent first and second molars in 6\u201315-year-old children using orthopantomographs \u2013 A cross-sectional study"],"prefix":"10.4103","volume":"44","author":[{"given":"Jayasri","family":"Selvakumar","sequence":"first","affiliation":[{"name":"Department of Pediatric and Preventive Dentistry, KSR Institute of Dental Science and Research, Tiruchengode, Tamil Nadu, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D.
