Comparison of selected oral microorganism among intellectual disabled people and normal people

Comparison of selected oral microorganisms among intellectual disabled people and normal people Objective: The aim of this study is to determine and evaluate the types and prevalence of selected microorganisms in the oral cavity of intellectual disabled patients compared to normal people. Material and methods: This study included sixty participants aged from 14-24 years old, 30 control healthy participants, and 30 case of intellectually disabled participants from the female day care center school diagnosed as intellectually disables. Saliva samples from the participants were tested for Streptococcus mutans , lactobacilli , and candida, as well as PH buffering capacity of saliva, using caries risk test (CRT) for Both Streptococcus mutans lactobacilli and PH, sabouraud agar medium was the culture medium for candida albicans. The statistical analysis included chi-square and Mann-Whitney U tests was carried out. Result: The case group show, colonies of streptococcus mutans ≥105 (56.7%) and <105 (43.3%) compared to the control group sample showed ≥105 (0%) and <105 (100%) . And for the lactobacillus case group showed ≥105 (73.3%) and <105 (26.7%) compared to control group ≥105 (43.3%) and <105 (56.7%). Candida was positive in 100% of case group, while control group was positive in 53.3% of the samples. For PH there was no significant difference for medium and high PH between the case and control group, but there is a difference for low PH in control group 3/30 samples (10%) and study group 11/30 samples (36.7%) Conclusion: The present cross sectional study suggests that there is a statistically significant difference in the candida and cariogenic bacteria (streptococcus mutans, lactobacillus) a high prevalence of the oral microorganisms (candida, SM, LB) among females with ID. There is a significant difference in low salivary PH in non-ID female patients compared to ID patients.
