Materials and Methods: A cross-sectional study was conducted using a self-administered questionnaire among 450 oral health professionals categorized into three groups (faculty, postgraduates, and interns) in Andhra Pradesh. The statistics were computed with the Statistical Package of Social Sciences version 22. Chi-square test and analysis of variance were used for statistical analyses.

Results: There was a statistically significant difference between the three groups regarding the P value denoted by (*) is considered as statistically significant, frequency of brushing, change of toothbrush, storage of toothbrush and knowledge on toothbrush disinfection (P value is 0.01), whereas knowledge on toothbrush contamination (P value is 0.04). P value denoted by (**) is considered as statistically highly significant. A highly statistical significance was noticed pertaining to the factors on type of toothpaste,reason behind change of toothbrush,contact between toothbrushes during storage and sharing of toothpaste with family members ( P value is <0.001).
