The purpose of this study was to examine the effect of morbid obesity and obesity on the decayed, missing, and filled teeth (DMFT) index and saliva values. Method: This study included 50 morbidly obese, 50 obese, and 50 control group patients aged 18-68 years. The DMFT index of the patients was determined through a clinical examination. The saliva kit was used to determine the saliva values [unstimulated saliva flow rate (USFR), stimulated saliva flow rate (SSFR), saliva viscosity (SV), saliva pH (SpH), and saliva buffering capacity (SBC)]. The patients were surveyed to learn about their oral health habits, nutritional habits, and socioeconomic status. Results: No significant difference was found in the number of decayed teeth, filled teeth, USFR, or SV between the groups (p > 0.05). The DMFT index, number of missing teeth, SSFR, SpH, and SBC all showed significant differences between the groups (p < 0.05). The significant variables associated with DMFT, according to the multiple linear regression model, were the frequency of dental visits (f3 = 0.365), age (f3 = 0.322), and SSFR (f3 = -0.256). Conclusion: Obese patients have a low saliva rate, low saliva pH, low buffering capacity, high DMFT index, and a high number of missing teeth.eninfo:eu-repo/semantics/openAccessDMFTObesitySalivaryTooth DecayArticle151919810.18521/ktd.12067901160769WOS:000957966500012Q3
