Objective: The goal was to discover the association of hormonal fingerprints with dental caries and malocclusion in our study.
Methodology: A total of 200 dental college students of the age-group of 18–25 years were randomly selected. The hormonal fingerprint was created by using a Vernier caliper to measure the length of the index and ring fingers and determine their ratio. Standard mouth mirrors and community periodontal index (CPI) probes were used to assess caries. According to the World Health Organization (WHO) assessment form, 2013, the sum of the number of Decayed, Missing due to caries, and Filled Teeth (DMFT) in the permanent teeth index was used to assess caries. Malocclusion was assessed by using the dental esthetic index. For statistical analysis, SPSS software was utilized.
Results: According to the findings, the majority of study subjects had a second digit to fourth digit (2D:4D) ratio of <1. Prevalence of malocclusion was observed to be increasing with an increase in 2D:4D ratio. Caries occurrence was also found to increase with an increase in malocclusion.
Conclusion: Our study confirms that hormonal fingerprints can be used as an early predictor for dental caries and malocclusion.
