摘要
Aim: Cyclooxygenase enzymes (COX) catalyze the conversion of arachidonic acid to prostaglandins and thromboxanes during pain and inflammation conditions. These enzymes have also been linked to several other conditions and diseases, and hence, in dentistry, it is crucial to identify the processes that increase the levels of these mediators. This paper aims to describe the significance of COX in dental practice through a narrative review. Methods: Articles relating to COX upregulation published in English and Spanish over the last 51 years in databases such as EBSCO, Google Scholar, Science Direct, PubMed, and Web of Science; were analyzed. Results: A total of 115 articles demonstrating the relationship between COX upregulation and multiple conditions and diseases of importance in prosthodontics, periodontics, oral pathology, orthodontics, and endodontics were included. Conclusions: COX upregulation is related to inflammatory and malignant diseases in oral tissues, such as periodontitis, pulpitis, and oral cancer, nevertheless, its expression is advantageous in other fields of study such as orthodontics. Additionally, is well documented that dental materials provoke an undesired increase in COX expression, which could be a significant factor that directly affects pulpal health
