Abstract

Background: Chronic periapical inflammation in maxillary anterior teeth leads to functional and aesthetic disturbances. However, detailed studies evaluating clinical features and assessing periapical lesions in two spatial dimensions and the extent of cortical bone involvement in this region are still lacking. Objectives: To investigate the clinical and paraclinical characteristics of maxillary permanent incisors with chronic periapical inflammation treated at the Ho Chi Minh City OdontoMaxillo-Facial Hospital from 2023 to 2024. Materials and method: A descriptive cross-sectional analysis study was conducted on patients aged 18-60 with maxillary permanent incisors affected by the chronic periapical inflammation, with lesion diameters ≤8mm. Participants were asked about their chief complaints and were examined for clinical symptoms related to pain, sinus tract, and vestibular swelling. Cone-beam computed tomography (CBCT) scans were used to assess the size and extent of cortical bone involvement by the lesion. Results: Thirty-one participants with a total of 53 teeth were included in the study. Reasons for visits included a history of pain (38.7%), sinus tract (35.5%), and vestibular swelling (25.8%). CBCT imaging revealed average radiolucency sizes of 3.78±1.80mm (buccolingual) and 4.03±2.11mm (mesiodistal). The group seeking treatment due to pain had smaller lesion sizes than the other two groups in both the Mesial-Distal (p<0.001, one-way ANOVA) and Buccal-Palatal (p<0.001, one-way ANOVA) dimensions. No correlation was found between radiolucency size and cortical bone involvement. Conclusion: The study emphasizes the importance of detailed history taking to predict the severity of apical lesions in chronic periapical inflammation in the maxillary incisor region.
