# Risk Factors associated with noncarious cervical lesions

## TL;DR

This study explores factors like bruxism, age, and diet in relation to noncarious cervical lesions in teeth, finding that age over 30 is strongly linked to these lesions.

## Contribution

The study identifies age as a significant risk factor for noncarious cervical lesions, while other factors like bruxism and diet show no significant correlation.

## Key findings

- Noncarious cervical lesions were observed in 46.6% of participants.
- Age over 30 years was strongly associated with NCCL (p < 0.001).
- Bruxism, stress, wear facets, and acidic diets showed no significant relationship with NCCL.

## Abstract

Noncarious cervical lesions (NCCLs) is the dental structure loss unrelated to caries. The aim was to investigate the possible relationship between bruxism, age, gender, daily routine and dietary habits and NCCL, and correlate with sensitivity and position in the dental arch.

245 patients aged between 18 and 40 participated in the survey, in which a questionnaire focused on parafunctional habits, erosion, abrasion, dental abfraction and acidic diet was conducted. Facial symmetry analysis, masseter hypertrophy, occlusion evaluation, and presence of wear facets and NCCL. Data were expressed as absolute and percentage frequency and were analyzed using the Fisher’s Exact/Chi-square tests and a multinomial logistic regression model.

NCCLs was observed in 46.6 % in the participants. Bruxism was observed in 64% of the individuals, and stress in 33%. Wear facets and acidic diets were reported in 75% and 60% of the sample, respectively. There was no significant relationship between NCCL and gender (p = 0.74), bruxism (p = 0.33), stress (p = 0.52), wear facets (p = 0.73), and acidic diets (p = 0.39). Age over 30 years was more strongly associated with NCCL (p< 0.001).

Age showed a direct correlation with noncarious cervical lesions. Factors including gender and dietary and parafunctional habits, such as bruxism, were not differential regarding the presence of NCCL.

Key words:Tooth wear, non-carious cervical lesions, bruxism.
