Is There Any Association Between Increased Over Jet And TMD…?? A Systematic Review.
Journal Title: International Journal of Dental Science and Innovative Research (IJDSIR) - Year 2019, Vol 2, Issue 1
Abstract
Aim: The aim of this systematic review is to evaluate whether there is any association between increased overjet and temporomandibular joint dysfunction. Data Sources: The search strategy was performed according to standard Cochrane systematic review methodology. The MEDLINE database, Cochrane Library, Ovid, EMBASE databases were searched. The inclusion and exclusion criteria were then applied for the studies to be included. The authors were contacted for further data. Results: Total 162 articles were retrieved. After reading the title and abstract of these articles, full text of 35 articles were retrieved for thorough evaluation. After reading the full text only 22 articles met the inclusion criteria and for final study only those articles were considered. Out of 22 articles included, in only 14 studies significant association between increased overjet and TMD was found and rest of the studies failed to identify significant and clinically important associations. 15 studies were of moderate (B) quality and 6 studies were of low (C) quality and one of the studies was a high (A) quality study. Individual variations in signs and symptoms of TMD over the time according to some studies further emphasized the difficulty in establishing increased maxillary overjet as a significant risk factor for TMD. Conclusions: Grade 3 evidence is found for this systematic review evaluating association between increased overjet and TMD. As strong evidence is not found, so there is still need for more standardised long term study.
