“…1,2 In such cases, presence of jaws of the victim might help in determining whether they are male or female. A number of studies have [11][12][13][14][15][16][17][18] shown that intercanine distance of the dental arch can be a useful variable in sexing of an individual. However, the measurements of distances between other teeth have not yet been studied exhaustively.…”

“…7 Though numerous studies are conducted on correlation between sex and tooth size, [8][9][10] there is limited literature on estimation of sex from various dental arch dimensions in Indian population and globally. [11][12][13][14][15][16][17][18] The available literature on estimation of sex using dental arch dimensions is limited to the sex differences between the intercanine arch width.…”

Sex estimation is one of the ''big three'' of human identification and is a vital aspect of the process of generating biological profile of unknown deceased. Anthropometric and odontometric methods that utilize measurement of distances between certain landmarks are commonly employed to differentiate between the 2 sexes. Teeth are the most robust and well-preserved parts of the human body, and studies have shown that the sex of an unknown individual can be estimated using their measurements. The present study was carried out to analyze the sex differences based on the dental arch dimensions of both the jaws in an Indian population. A proper understanding of dental arch dimensions not only help forensic odontologists in human identification, but also help dental practitioners in teeth restoration, and to quantify selection of anterior teeth in bonding of dentures. The dental arch dimensions of the canines, premolars, and the molars of both the jaws were recorded in dental casts of 307 participants. Comparison of the dental arch dimensions of males and females was done and logistic regression models were generated to estimate sex. Receiver Operating Characteristic analysis was done to find out the potential to estimate sex for all the dental arch dimensions in both the sexes. It was observed that maxillary intermolar II distance gave the best results in estimating the sex. The sexing accuracy is seen to increase as we go distally from canines to molars in each jaw; minimum for intercanine distance and maximum for distance between the 2nd molars. The sexing accuracy from dental arch dimensions was found to be between 72.7% and 86.5%. The models derived for estimation of sex from dental arch dimensions can be used in cases of skeletal remains.

“…Externally, the most sexually dimorphic portions of the body are the chest, the lower half of the face, and the area between the waist and knees. 6 Although the DNA profile gives accurate results yet measurement of linear dimensions such as anthropometric or odontometric parameters can be used for the determination of sex in a large population because they are simple, reliable, inexpensive, and easy to measure. The fact that most teeth complete development before skeletal maturation makes dentition a valuable sex indicator, particularly in young individuals.…”

Aim and objective: To measure the mandibular canine dimension, intercanine distance, and calculate the mandibular canine index (MCI) to assess their usefulness in gender determination. Materials and methods:The study was performed on 60 boys and 60 girls. Impressions of both the arches were made using alginate material, poured in dental stone, and was allowed to set and then the cast bases were made with dental plaster. A digital Vernier caliper was used for obtaining the measurements. The intermolar arch width, intercanine width, and MCI were calculated. Sexual dimorphism was calculated using the formula given by Garn and Lewis. The data were statistically analyzed using the unpaired "t" test. Results: There was no statistical significance seen in the mandibular intermolar and intercanine distance between the two groups. The MCI between males and females showed a statistically significant difference. Conclusion: Intermolar distance, intercanine distance, and MCI can be used as an alternative tool for sex determination as an inexpensive and alternative method. Clinical significance: The first study in itself to determine gender in the pediatric population in the city of Davangere, India.

Introduction: The alterations in the arch form during treatment are dictated by the dimensions of the archwires. Objective: This study aimed to determine the mean arch dimensions of a sample of Pakistani subjects and to evaluate the conformity of preformed archwires with mandibular arch form. Methods: The dental records of 1,500 adult subjects were evaluated. The mandibular casts of 42 subjects (males = females = 21) with balanced facial profile, Class I occlusion, ideal overjet and overbite were included. Brackets were bonded on all teeth. Arch dimensions were evaluated at canines, first premolars, second premolars, first and second molars, with digital vernier calipers. The arch widths at the level of aforementioned teeth were evaluated on the digitized archwires, using the mean arch depths of the subjects. Results: In males, the archwires were found to be wider at canines and premolars, and significantly narrower at first (p< 0.001, 95% CI = 2.03 - 5.74) and second molars (p< 0.001, 95% CI = 2.29 - 7.73) as compared to the arch dimensions of the mandibular casts. In females, the archwires were significantly narrower at canines (p< 0.001, 95% CI = 1.4 - 3.97), and first (p= 0.02, 95% CI = 0.402 - 4.41) and second molars (p< 0.001, 95% CI = 1.76 - 6.13). Conclusion: No single commercially available archwires evaluated in the present study conformed to the arch dimensions of our subjects. Utilization of the currently available archwires may result in unwarranted modification of arch form, which may lead to unstable post-treatment teeth position.
