Aim: This study aimed to compare the incidence of mucosal lesions and pain during orthodontic treatment with fixed versus removable orthodontic appliances.
Methods: This cross-sectional study involved 58 patients with fixed orthodontic appliances and 58 patients with removable orthodontic appliances, all aged between 15 and 30 years. The presence and location of lesions were recorded at two time points: two weeks and four weeks after the start of the study. Additionally, the level of pain experienced by the patients was quantified at these same time points using a Visual Analog Scale (VAS). The Chi-square test was used to compare the frequency of oral lesions between the two groups at the onset of treatment. The Kruskal-Wallis test was used to compare the pain score at the onset of treatment between the two groups. The level of significance was set at 0.05.
Results: The frequency of traumatic lesions at two and four weeks was significantly higher in the fixed group (P<0.050). The frequency of traumatic and allergic lesions increased with time in both groups (P<0.050). Lichenoid reactions, candidiasis, and exophytic lesions were only detected in the removable treatment group. At two and four weeks, the frequency of lesions in the buccal mucosa was significantly higher than in other areas in the fixed group (P<0.050). At four weeks, the pain score of patients was higher in the fixed treatment group (P<0.050).
Conclusion: At four weeks, the frequency of lesions was higher in the fixed group. Buccal mucosa was the most common location of lesions in both groups. Pain in the fixed group was higher than the removable group at four weeks.

Self-ligating brackets are ligature-less brackets with the mechanical device built into them to close edgewise slot. It was claimed that self-ligating brackets (SLBs) have advantages over conventional-ligating brackets brackets (CLBs). The most claimed advantageous feature is reduced friction between the archwire and the bracket and full archwire engagement, resulting in faster alignment and space closure. Greater arch expansion with less incisor proclination, also faster ligation, reduced number of visits and less pain is mentioned as the beneficial features of SLBs in different articles. In this review article, we compared SLBs with CBs in aspect of resistance to sliding, speed of archwire ligation, quality of alignment and amount of pain during treatment base on the most recent articles published in literature. We concluded that although self-ligating brackets are proved to have some advantages over conventional brackets, but more studies are needed to discard doubts about using them, routinely.
