Abstract

This multicenter retrospective study investigated the occurrence of oral mucosal thermal and chemical burns during endodontic operations conducted by dental students at Menoufia University (MU), Horus University in Egypt (HUE), and the Modern University for Technology and Information (MTI) over one year. A total of 4,791 clinical records were evaluated. MU identified 42 oral reactive lesions among 1,221 patients (3.4%), including 12 chemical and 30 thermal burns. HUE identified 63 lesions among 1,750 patients (3.6%), comprising 18 chemical and 45 thermal burns. MTI recorded 71 lesions among 1,820 patients (3.9%), including 21 cases of chemical and 50 cases of thermal damage. These adverse incidents reflect inadequate training, improper isolation, or improper management of materials and tools. The significant occurrence of thermal burns underlines concerns connected with heated obturation devices (Cohen & Hargreaves, 2016; Al-Jadaa et al., 2017). Chemical burns, usually caused by sodium hypochlorite, are frequently the result of inadequate irrigation safety (Spencer et al., 2007; Hülsmann & Hahn, 2008). To prevent such consequences, enhanced supervision and thorough clinical training are required.
