ABSTRACT
Background: Gingivitis and periodontitis cause significant damage to soft tissues and structures like periodontal ligament and alveolar bone. There is very high prevalence of obesity, diabetes, gingivitis, and periodontitis in Saudi adult population. Aim of this study: Currently we are investigating the prevalence of gingivitis and chronic periodontitis in Saudi adult male diabetic population, and its consequences on oral health; additionally we analyzed any possible differences in the distribution of ABO and Rh (D) blood groups between adult male gingivitis and periodontitis patients. Methods: Extensive oral exams were performed by dental interns on a total of 1000 randomly selected adult male subjects to record their blood type. Their oral cavities were thoroughly examined for presence of dental carries, gingivitis, periodontitis, tooth decay and, or tooth loss. Data was carefully recorded and statically analyzed using Z calculator. Results: Gingivitis was more prevalent and statistically significantly higher in A blood group as compared to periodontitis (p ? .01). In contrast there was significantly lower distribution of AB blood groups among male gingivitis patients in comparison to periodontitis patients at (p ? .01). Although there was no significant change in distribution of B or O blood groups between male gingivitis and periodontitis patients, there was still a statistically significant increase in distribution of O blood groups in male periodontitis patients as compared to non-O blood group distribution. Overall there was a significant increase in Rh individuals and significant corresponding reduction in Rh- individuals in male gingivitis patients as compared to male periodontitis patients at p ? .01. Conclusions: There are statistically significant differences in ABO blood group distributions between the male gingivitis and male periodontitis patients. Key words: ABO and Rh blood groups, diabetes mellitus (T2DM), HbA1c, Obesity, gingivitis, periodontitis
