The statistical analysis encompassed comparisons of chewing efficiency between groups and between baseline and posttreatment within each group, employing analysis of variance (ANOVA) and paired <i>t</i> tests, respectively.</p><p><strong>Results: </strong>Using the paired <i>t</i> test, a significant difference in chewing efficiency values as expressed by the median particle size was observed between the baseline and 6-month values in all groups (<i>P</i> < 0.05), except for group I where no significant change was noted over the 6 months (<i>P</i> > 0.05). The one-way ANOVA test revealed a statistically significant difference among groups following therapies (<i>P</i> ˂ 0.05). The <i>post hoc</i> Tukey test was employed for pairwise comparisons and revealed statistically significant variances in the main values of chewing efficiency among all groups at a 95% confidence level (<i>P</i> ˂ 0.05).</p><p><strong>Conclusion: </strong>The study's results suggest that occlusal splints and LLLT are more effective in improving chewing efficiency than behavioral interventions.</p>","PeriodicalId":47247,"journal":{"name":"Journal of International Society of Preventive and Community Dentistry","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2024-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11141894/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141200960","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
