Cervical Abrasion, Sexual Dimorphism, and Anthropometric Tooth Dimension

Abstract

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.

Evaluation of CoVid-19 infection among vaccinated and unvaccinated individuals using biochemical markers

“…The maximum number of reported cases of CoVid-19 infection were from partially vaccinated group 50.7% (took only first dose of vaccine) than fully vaccinated group 49.3% among the 280 vaccinated individuals. Similar findings were reported with Ali et al 2022 [ 10 ]; Amit et al 2021 [ 11 ]; Keehner et al 2021 [ 12 ]; Sabnis et al 2021 [ 13 ] and Kandeel et al [ 14 ]. Shahapur et al 2022 [ 8 ] reported the most of the symptomatic patients of infection were suffered with episodes of fever, headache, sore throat, fatigue, cough, and breathlessness.…”

Assessment of Cervical Abrasion, Dentin Hypersensitivity, and Its Treatment Needs Using the Cervical Abrasion Index of Treatment Needs Probe

“…The buccolingual measurement of each tooth was performed using the CAITN probe [ 12 , 13 ]. The depth of the lesion was measured by placing the probe perpendicular to the long axis of the tooth at the center of the lesion.…”

The Cervical Abrasion Index of Treatment Needs (CAITN) Procedure for Population Groups and Individuals

“…The CAITN index was created using data from prior extensive research [16][17][18][19][20] to inform treatment choices. The authors examined 840 teeth from 30 participants, with a mean age of 48.4 years, and with or without cervical abrasions [16,19]. Using a CAITN probe [18], we recorded the buccolingual dimension of each tooth.…”

“…A mouth mirror was used for withdrawal and better visibility to avoid gingival puncturing in the buccal and palatal minor region of the gingiva, and the bills of the CAITN test were inserted into the deepest part of the cervically scraped spot. Some portion of the tooth is opposite to the long hub of the tooth to record buccolingual measurements [ 19 , 20 ]. The depth of the cervical abrasion may be calculated by comparing the reading on the CAITN probe scale with the mesiodistal and buccolingual measurements of the affected tooth, all of which are standardized.…”
