Abstract
Abstract Objective The goal of primary and secondary endodontic treatment is to eliminate the cause of inflammation inside the tooth and in the surrounding tissues. When the inflammation from the root canal system of the tooth spreads beyond the apex of the root, periapical changes in the bone tissue and, in the case of upper premolars and molars, inflammatory changes in the Schneider membrane may occur. Materials and Methods In a retrospective documentation analysis of root canal treatments, three-dimensional (3D) computed tomography images before and after endodontic treatment were assessed to measure the thickness of the Schneider membrane. Forty-five endodontically treated patients aged 21 to 62 years were enrolled in the study. Inflammation of the maxillary sinus was considered when the Schneider membrane was thicker than 2 mm. Statistical analyses were performed with Statistica 12 by StatSoft and StatXact by Cytel using the Shapiro–Wilk test, Student's t-test, and the Mann–Whitney test. Results Out of 12 comparisons between variables, only 3 comparisons were significant. There was a relationship between the treatment effect (reduction in maxillary sinus inflammation 3 months after treatment) and the maximum height of the Schneider membrane (p = 0.004). There was a relationship between the presence of a periapical lesion and the minimum height of the Schneider diaphragm (p = 0.02), and there was a relationship between the presence of a periapical lesion and the maximum height of the Schneider diaphragm (p = 0.04). Conclusion Primary and secondary root canal treatments of maxillary premolars and molars reduce the inflammation of the maxillary sinus 3 months after treatment.
Highlights
Performed endodontic treatment allows for a reduction in inflammation in the maxillary sinus to be observed as early as 3 months after the end of treatment
There was a relationship between endodontic treatment and a reduction in maxillary sinus inflammation
The age of the person undergoing treatment may have an influence on the healing process, as healing ability potentially declines with age; this study found no influence of age or sex on the process in the maxillary sinus.[13 14,15]
Summary
Contemporary antiseptic root canal treatment (or endodontic treatment) consists of removing the infected pulp and root canal dentine from the tooth cavity through biomechanical and chemical preparation of the root canal system and filling them securely. The prognosis for antiseptic root canal treatment is good, provided that the treatment is performed in accordance with. Healing in Sinus after Endodontics Migas, Marchlewska 47 the applicable standards (chemomechanical removal of the infected tissue and complete filling). Improvement or elimination of apical lesions within a few months after the end of treatment indicates a good result of endodontic treatment. For this reason, periodic clinical and radiological check-ups are recommended after antiseptic root canal treatment.[1]
