In-vivo evaluation of multiple factors association with non-carious cervical lesions

Abstract

Aims: In vivo-evaluation of multiple factors associated with non-carious cervical lesions.

Material and Methods: This in vivo study consisted of a clinical survey of NCCL & its relation with oral hygiene practice, tooth brushing habits, parafunctional habits, chewing habits. The subjects were clinically examined to detect presence and location of NCCLS, signs of parafunctional habits and chewing habits. According to the presence and absence of NNCLthe participants were divided into two groups- control group (no NNCL presence) and a test group (NCCL present). After the examination participants were asked to fill an oral hygiene practice self-report questionnaire. To examine the deformation of tooth brush bristles each participant was given a new and identical extra soft tooth brush incombination with a tooth paste. The participants were requested to use the tooth brush andtooth paste for their normal daily tooth brushing for 30 days and were collected to analyze the deformation of bristles.

Statistical analysis: The deformation of tooth brush bristles was statistically associated with Presence of NCCL'S (p <0.01)

Results: In this in vivo study we found that 78% of population of test group with presence of non-carious cervical lesions showed deformation of tooth brush bristles whereas 84% of population of control group showed no deformation of tooth brush bristles with absence of non-carious cervical population. Also 68% of total population showed light to moderate deformation.

Conclusions: This study concluded that there is positive correlation between prevalence of NCCL and tooth brushing habits.
