Background: Salivary secretor status and ABO blood group are important in clinical and forensic medicine. In addition, both may have impact on some oral disease status.
Objective: To assess the correlation between ABO blood group, salivary secretor status and dental caries and to evaluate which type of ABO blood groups is associated with an increased risk for dental caries.
Materials & Methods: Cross-sectional study was carried out on 30 dental caries female patients aged between 20 to 50 years, attending to College of Dentistry, Umm Al-Qura University. Caries experience was assessed by using WHO index and DMFT score. Then, ABO blood grouping was done by slide agglutination method and 1 ml of unstimulated saliva is collected in a sterile test tube. Hemagglutination inhibition test was performed to analyze the salivary secretor status. The collected resulted data were tabulated and statistically analyzed using (SPSS) version 20.0.
Results: DMFT index scores were different among the four ABO blood groups; however, the differences were statistically insignificant (p> 0.05).On the other hand, salivary secretor status was different among the four blood groups with highest percentage of secretors were of blood group A (85.7%) and those of non-secretors were of blood group AB (60%). The mean values of DMFT index were higher in non-secretor than secretor status; however, the differences were statistically insignificant (p > 0.05).
Conclusion: With the study limitations, it could be concluded that, although higher percentage of ABO blood group non-secretors have dental caries than secretors but the difference was non-significant.
