Relationship Between Plaque Score and Cariogram Risk Prediction Parameters among Patients Visiting A Dental Institution: Retrospective Study

Etiology of dental caries is multifactorial.Currently, caries risk assessment models contain a combination of factors such as diet, fluoride exposure,a susceptible host, microflora that interact with the variety of social, cultural and behavioural factors. The aim of the study was to assess the relationship between plaque score and cariogram risk prediction parameters among patients visiting a dental institution in Chennai. This was a retrospective institutional study. Samples were collected from June 2019 to March 2020 from patient records who visited a private dental hospital. Sample size was about 221. Details on plaque score and cariogram factors were collected from patient records and tabulated in microsoft excel tabulation and analyzed using SPSS. P<0.05 considered significant. Mean age of males and females were found to be 33.3479 and 36.7212 years and the difference is statistically significant(p<0.05). The mean of plaque index score in male and female was found to be 1.3346 and 1.4497, mean percentage of avoiding new cavities was found to be 45.3846 in male and 42.6250 in female, mean of circumstances was found to be 11.5812 in males and 11.2692 in females, mean of bacteria was found to be 16.2564 in males and 18.0865 in females, mean of susceptibility was found to be 16.9658 in males and 19.2885 in females, mean of diet was found to be 9.1026 in males, 8.8654 in females. There was no association between gender and plaque index score, cariogram categories(p>0.05) and no correlation between plaque index score and cariogram risk factors. Within the limitations of the present study, we can conclude that there is no correlation between plaque score and cariogram risk factors.
