Enamel of Premolars whose Predecessors Presented Rupture of the Follicle Bone Crypt from Periapical Infections

Abstract

Objective: To observe if dental alterations in premolars are associated with the rupture of the follicle bone crypt caused by a periapical lesion in the predecessor molars. Study design: This is a cross-sectional study. Data collection consisted of the analysis of medical records, a socioeconomic questionnaire, and dental clinical examination. Records from patients with a history of a radiographically visible periapical lesion in lower primary molars submitted to pulp therapy or extraction from a university dental clinic were selected. Successor premolars were clinically evaluated for the presence of enamel development defects, shape alterations, and eruption deviations. The descriptive analysis of data was performed, and Fisher’s exact tests, linear trend chi-square, and the Student’s t-test were applied. Results: Forty-eight permanent teeth were from 36 patients were evaluated in this study, and 20 (41.7%) of the 48 examined premolars showed a radiographic image suggestive of the rupture of the bone crypt. Rupture of the follicle bone crypt was not associated with the occurrence of enamel alterations in premolars (p = 0.418). An association between dental alterations and age over six years at the time of intervention was observed (p = 0.043). Conclusion: The presence of enamel alterations of premolars was not associated with the rupture of the follicle bone crypt caused by a periapical lesion in predecessor molars.

Effect of Chronic Apical Periodontitis in Primary Molars on Succedaneous Permanent Teeth: An Observational Retrospective Study

“…An increase in the severity of infection in the primary dentition led to a corresponding increase in follicular damage sustained by the succeeding permanent teeth. This was in accordance with a previous study [ 12 ]. This might be due to the presence of inflammatory mediators, such as interleukin 1 alpha and beta (IL-1α and IL-1β, respectively), in periapical infections of the primary teeth, which are related to osteoclastic resorption, stimulating lymphocytes, and neutrophils [ 13 ].…”
