dc.description.abstractDental fluorosis is a foremost public health problem in many countries, including India. Very few studies investigated gene polymorphism and risk of dental fluorosis. Genetic polymorphisms in Collagen Type I, alpha 2 (COL1A2) gene, found to be linked with bone pathogenesis, may affect the tooth formation resulting in the vulnerability to dental fluorosis. Aim: To assess the association between COL1A2 (PvuII) gene polymorphism and risk as well as severity of dental fluorosis. Methods: The present case control study was conducted among participants with (n = 60) and without (n = 60) dental fluorosis. Dental fluorosis was assessed using Modified Dean’s fluorosis index (1942). The PvuII polymorphisms (in exon 25) inside the COL1A2 gene were genotyped by Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) procedure. Statistical analysis were carried out with Chi-square test and Odds Ratio (OR) was determined with multivariate logistic regression analysis. Results: The genetic polymorphism in COL1A2 PvuII was found to be associated with the risk of dental fluorosis which was highly significant (p< 0.001). The odds ratio was 31.4 times [OR = 31.9, 95% CI: 3.9–48.7] higher for the homozygous PP genotype group and 4.0 times [OR = 4.0, 95% CI: 1.0–10.7] higher for the heterozygous Pp genotype.en_US
