Cone-beam dental computerize tomography for evaluating changes of agingin the dimensions central superior incisor root canals

ABSTRACT

Objectives: Cone-beam dental computerize tomography (CBCT), a noninvasive imaging method, was used to imagethe pulp-dentin complex. Pulp changes histologically with aging. While many studies have investigated thehistological changes in pulp, few studies have focused on the changes in the shape of the root canals. This studyevaluated the changes in the root canals with aging of central superior teeth using CBCT.Study Design: The study examined 100 non-carious maxillary central teeth. These teeth were divided into five groupsaccording to the age of the patients Group A15‑24, Group B 25‑34, Group C 35‑44, Group D 45‑54 and Group E 55years and older. CBCT was used to determine root length, and pulp width at the cervical, apical 1/2, and apical 1/3.Results: On comparing the groups using one-way analysis of variance (ANOVA), the root length did not differ (P >0.05), while the pulp width at the cervical, apical 1/2, and apical 1/3 differed between the groups (P < 0.001).Conclusions: The pulp length did not change with aging, while the pulp width did change. CBCT can be used todetermine the precise root length and width, to prevent iatrogenic exposure of the apex, complementing existingmethods. This will improve the prediction of the prognosis of root canal treatment (AU)
