Secondary dentin deposition is a regular ageing process and can be utilized in dental age estimation when development and eruption parameters cannot be utilized.Methods: In total, 38 monoradicular teeth of Nepalese subjects were assessed for tooth pulp ratio. Intraoral periapical radiographs of these teeth were taken, and pulp tooth ratio was calculated and dental age was estimated.Results: The mean chronological age was 46.79 years and the mean estimated age was 44.32 years. The pulp\/tooth area ratios calculated were in the range of 0.012 to 0.195, and 0.052 to 0.256 for mesio-distal and bucco-lingual planes respectively.Conclusions: Pulp tooth ratio of maxillary lateral incisors and mandibular lateral incisors showed the highest correlation with values of 90% and 76% respectively. Mesio-distal assessment was more accurate in dental age estimation than bucco-lingual view.Keywords: Age estimation by teeth; dental pulp; dental radiograph; pulp tooth ratio; secondary dentine<\/jats:p>","DOI":"10.33314\/jnhrc.v19i3.3614","type":"journal-article","created":{"date-parts":[[2024,11,26]],"date-time":"2024-11-26T08:53:27Z","timestamp":1732611207000},"page":"577-581","source":"Crossref","is-referenced-by-count":3,"title":["Age Estimation Using Monoradicular Teeth by comparing Pulp\/Tooth Area Ratios between Bucco-lingual and Mesio-distal Periapical Radiographs"],"prefix":"10.33314","volume":"19","author":[{"given":"Samarika","family":"Dahal","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrew","family":"Forgie","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Scheila","family":"Manica","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"18778","published-online":{"date-parts":[[2021,12,14]]},"container-title":["Journal of Nepal Health Research Council"],"original-title":[],"deposited":{"date-parts":[[2024,11,26]],"date-time":"2024-11-26T08:53:37Z","timestamp":1732611217000},"score":1,"resource":{"primary":{"URL":"https:\/\/jnhrc.com.np\/index.php\/jnhrc\/article\/view\/3614"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,12,14]]},"references-count":0,"journal-issue":{"issue":"03","published-online":{"date-parts":[[2021,12,15]]}},"URL":"https:\/\/doi.org\/10.33314\/jnhrc.v19i3.3614","relation":{},"ISSN":["1999-6217","1727-5482"],"issn-type":[{"value":"1999-6217","type":"electronic"},{"value":"1727-5482","type":"print"}],"subject":[],"published":{"date-parts":[[2021,12,14]]}}}
