Abstract

Background: The term Erosion is not due to a single factor but multifactorial due to acids, mechanical wear and tear, trauma from axial and non-axial loads. The aim of the study was to evaluate the influence of local factor, the pH of gingival crevicular fluid on dental erosion. Materials and methods: The 200 adult volunteers of both sexes 30-50 yrs of age were involved in the study. Saliva and GCF samples were collected in the morning from 2 to 3 hours after breakfast with the help of proximal strips. The criteria for gingivitis was evaluated by measuring the plaque index, the gingival index, probing depth and bleeding on probing (BOP). Participants were divided into two groups: Control group-Normal gingiva (n=100) and moderate and severe gingivitis (n-100) with cervical lesions. Results: The collected data were analysed with IBM.SPSS statistics software 23.0 Version. The pH of GCF and Saliva were near neutral (6.5 and 6.4) in patients without gingivitis. In moderate and severe gingivitis, the pH was 5.4 and 6.1 of GCF and Saliva (P≤0.05). Conclusions: The pH of gingival crevicular fluid can be a contributing factor in the etiology of dental erosion in the process of lowering pH near enamel and dentin in the cervical areas.
