“…This study revealed significant gender dimorphism in the MD width and ICD of the maxillary canines, with males showing larger corresponding mean values than females, which was in accordance with previous studies [24,30,31]. The results of gender dimorphism of the maxillary canine in the present study showed a greater dimorphism in the MD width of the right canine (3.5%), followed by ICD (3.14%).…”

“…Contrary to this, a previous study among the Saudi population had reported no statistically significant differences in the mean MD width of right and left maxillary canines between the genders [16]. Another study in Nigeria, however, had reported that the MD width of the left maxillary canine was significantly higher in males than in females [31].…”

The present study aimed to analyze the gender dimorphism in odontometrics of permanent maxillary canines using a three-dimensional digital method and to test the accuracy in gender estimation using discriminant function analysis in a sample of the Saudi population. A total of 120 diagnostic dental casts of patients aged 16–29 years were used in the present study. Plaster models of their maxillary dentition obtained from the archives were scanned and digitally measured using a three-dimensional digital method. The mesiodistal width of the right and left maxillary canines and intercanine distance were measured. Gender dimorphism was established using the Garn method. Data were statistically analyzed using descriptive statistics, the Mann–Whitney U test and discriminant analyses. Males showed larger mean dimensions of canines than females with regard to both mesiodistal width and intercanine distance, and the difference was statistically significant (p < 0.05). The right maxillary canine mesiodistal width showed a higher percentage of gender dimorphism (3.5%). Discriminant function analysis showed that the overall accuracy of gender prediction was 80.5% for the multivariate analysis. The univariate discriminant function equation revealed that intercanine distance was the most accurate predictor of gender (78%), followed by the right canine mesiodistal width (76.3%). The use of three-dimensional technology for odontometrics presents a promising method, and permanent maxillary canine parameters can be used as an acceptable ancillary tool for gender estimation in forensic science.

“…It should be noted that there is also an MCI using the same measurements except in the upper dentition (Bakkannavar et al, 2015;Nuhu et al, 2019;Otuagn et al, 2019;Phulari et al, 2017;Rani, 2017). In previous studies, it was found that the Maxillary Index results were not as significant as the Mandibular Index ones and thus not as accurate at assessing sex within the Indian populations (Nuhu et al, 2019;Otuagna et al, 2019). Other studies found that the Maxillary Canine Index was not significant at all and should not be used as a sexing method (Bakkannavar et al, 2015;Phulari et al, 2017).…”

“…They validated the MCI on a population from Nice, France and concluded that correct tooth alignment within the alveolus is important and that a standard MCI needed to be calculated for each population. More recently, standard MCI has also been calculated for Nigerian populations (Nuhu et al, 2019;Otuahn et al, 2019), Pakistani populations (Hassan & Meman, 2018;Hussain et al, 2012;Shahid et al, 2018), Nepali populations (Acharya & Mainali, 2007Bajracharya et al, 2018;), a Chinese population (Iqbal et al, 2015); a Bosnian population (Muhanedagic & Sarjic, 2013), a Brazilian population (Sassi et al,2012 ), an Iraqi population (Ahmed et al, 2014) and a British population (Hussain et al, 2012; Table 1). A meta-analysis performed in 2018 found at least 26 studies utilizing the MCI between 2000 and 2016 (Dony et al, 2018).…”

Rao and colleagues created the Mandibular Canine Index (MCI) as a method of sex assessment. It has primarily been used on living South Asian populations. This study applies the Index to two decedent American populations in hopes that it will applicable to the field of Forensic Anthropology. Forty-five individuals from the C.A. Pound Human Identification Lab and the Wichita State Biological Anthropology Lab with full mandibular dentition were studied. The mesio-distal width of both right and left canines and the canine arch width were taken and the MCI calculated along with the standard MCI. Results show that the MCI is not statistically significant in determining males from females (p=.461 for right and p=.473 for left). The standard MCI was .242 for the right and .246 for the left. This gave an accuracy of 37% to 44% for males and 44% to 45% for females. The mesio-distal length (p = .002 for right and .001 for left) and canine arch width (p=.019) on their own were statistically significant and can be used in sex assessment if the teeth are present although they should be used with other methods. Further study should be done with a larger sample size to see if results are consistent.

“…Though in many aspects, teeth or the arch pattern of the male and female are similar; they still possess some differences which help to determine their gender. Literature showed numerous studies for gender identification of the individuals by using several hard and soft oral tissues and methods such as; rugoscopy 1,2 , cheiloscopy 3,4 , palatal depth 5,6 , inter-canine width 7,8 , inter-molar width 9,10 , and mandibular canine index [11][12][13] etc.…”

Introduction: It is critical to identify the person in a criminal investigation process. Forensic odontology helps in the identification of the person using dentofacial structures as a differentiating tool in the criminal justice system. Several oro-dental anatomical landmarks like palate, lips and bite marks, teeth such as maxillary central incisors, canines and molars have been used in the identification of the gender of an individual based on the principle of individuality. Aims and objectives: Studying different odontometric methods such as palatal depth, mandibular canine index and maxillary inter-canine width for sex determination and compare it with the actual gender of an individual. Methodology: For this study, 72 pairs of orthodontic study models were analysed for gender determination based on three odontometric parameters viz. palatal depth, mandibular canine index and maxillary inter-canine width. The patient’s sex was not disclosed to the investigators until the completion of the model analysis. The measurements were taken using brass wire, divider, stainless steel scale and digital vernier calliper. The data was calculated and tabulated in a master chart and statistical analysis was done. Result: The results of odontometric measurement methods used for the gender determination study are in actual agreement with 32.6% male and 63.04% female population of Mumbai and the sub-urban region. Conclusion: The palatal depth, maxillary inter-canine width and mandibular canine index are simple, convenient, reproducible and reliable odontometric methods in the gender determination of individuals.
