Introduction: The aim of this study was to analyze the anatomic crowns of the maxillary and mandibular dentition concerning the mesiodistal, buccolingual measurements which will be used to establish normative data as a part of comprehensive study being carried out to determine the depth of the cervical abrasion (CA) of the individuals by predicting the CA Index of Treatment Needs (CAITN) score. Materials and Methods: A newly developed instrument termed as CAITN probe was used to measure CA of the tooth more quantitatively. The mesiodistal and buccolingual width of all the 14 maxillary and mandibular teeth from the right second permanent molar to the left second permanent molar of the study sample was measured. The ratio between buccolingual and mesiodistal measurements of each tooth of the maxillary and mandibular arch of the study sample (n=100) was also determined. Statistical analysis was performed using the SPSS 26.0 software. Results: Descriptive statistics were calculated for each group independently. The statistical significance of the difference in mean in mesiodistal and buccolingual diameters between males and females was calculated using the t-test for independent samples with p < 0.05. The ratio was highest in the left second premolar (1.752) and least in the right central incisor (0.980) of the maxillary arch. Similarly, the ratio was highest in the left central incisor (1.723) and least in the left second molar (0.910) of the mandibular arch. Conclusion: The present study was conducted as an initial step in the process of development of the novel tool or index enabling the dentists to organize the health-care needs of their patients by facilitating standardized identification of CA with objective measurements used for epidemiological or community purpose.
