Estimation of human somatype using inter-canine and inter-premolar distances of the maxillary arch
Context: The establishment of a correlation between tooth dimensions and body size is crucial within the realm of forensic odontology. While numerous investigations have focused on the association between tooth morphology or width and stature, limited reports exist regarding the correlation between overall body structure or build and odontogenic parameters. This study focuses on finding a correlation between inter-arch dimensions and the body build of an individual. Aims: This study aimed to examine the potential correlation between an individual's somatotype (body build) and the measurements of inter-canine and inter-premolar maxillary arch widths. Study Settings: Dayananda Sagar College of Dental Sciences. Study Design: A cross-sectional study. Methods and Material: The sample size of the study was 153 individuals aged 18-25 years. Impressions for the maxillary arch were taken, study models were made and inter-arch measurements were taken using a digital Vernier calliper. For body build measurements, Heath-Carter somatotype measuring technique was used. The collected data were entered into an Excel sheet, and statistical analysis was done. Statistical Analysis Used: Principal component analysis. Results: On using principal component analysis, it was seen that there exists no correlation between body build of an individual when compared to inter-canine and inter-premolar distances. Conclusions: While no positive correlation has been seen between the odontometric parameters and specific body type, it can be argued that this can be due to the cited limitations of the study. Hence, we conclude with the note that a more detailed study would offer more viable and credible results.
Stature estimation using various odontometric parameters: A narrative review
Aim: Indonesia is the most disaster-prone country in the world, which can cause many dead victims, therefore, the identification process becomes essential, but the difficulties increase when only the skulls, partial jaws, and teeth remain found in the body. Some researchers began to pay attention to estimating stature through teeth dimensions because teeth have high individual characteristics and are the most muscular body structures. This study aims to describe several studies and methods that have been used by researchers from outside Indonesia in estimating stature using odontometric parameters. Materials and Methods: This narrative literature review was conducted by reviewing several studies of stature estimation using odontometric parameters based on PubMed Central and indexed articles and documents published by authorities and boards. Some of the methods found and included in this study include parameters of maxillary permanent dentition, mandibular permanent dentition, all maxillary and mandibular permanent dentition except third molars, and also deciduous dentition. Result: From all parameters above, the easiest method and most applicable in Indonesia is the method using permanent mandibular dentition because it uses the Carrea's index formula, so the measurement becomes easier and faster to get the desired result. Conclusion: The odontometric parameters used to estimate height vary greatly, although some still showed a low-moderate relationship to height. Carrea's index is one of the easiest, cheapest, and most reliable and straightforward methods to estimate the height.
Reliability of odontometric parameters in stature analysis
Background: To emphasize the role of odontometric parameters which may be used as a reliable forensic tool especially in cases with partial remains of the individual Aim: To assess the reliability of odontometric parameters in stature analysis Materials and Methods: The study was conducted on 100 patients (50 male and 50 Female). Mesiodistal width of anterior teeth, inter-canine width, Inter-premolar width and maxillary arch length were the parameters included. The results were tabulated with a linear regression formula obtained for each parameter. Statistical Analysis: The data collected was statistically analysed using SPSS version 20 and a linear regression formula was obtained thereafter. Results: Mesio-distal widths of individual maxillary canines, total mesiodistal width of maxillary anteriors and arch length showed a significant co-relation with stature. The combined linear regression formula was obtained for all parameters. Conclusion: Odontometric parameters of mesio - distal widths of individual maxillary canines, total mesiodistal width of maxillary anteriors and arch length can be used as reliable parameters for stature analysis.
Odontometric parameters as a forensic tool for stature estimation among three Asian ethnicities
Background The height of an individual in the upright posture is referred to as stature. The evaluation of the stature of an individual is an essential step in identification. Estimation of stature is commonly performed using the long bones as they positively correlate with the stature. The correlation between the dimensions of the skull, jaw and stature of an individual has been reported among specific populations. To date, only a few studies have correlated odontometric parameters with stature among populations. Teeth and oral structures can be used to estimate the stature of an individual. The objective of our study was to determine and establish a relationship to estimate the stature of individuals among three different Asian ethnicities using four odontometric parameters as a forensic tool. The Asian ethnicities chosen in our study were Malay, Indian and Chinese. The five parameters were the height of an individual, intercanine width, interpremolar width, arc length and mesiodistal dimension of the six anterior teeth. The height was measured with the individual standing upright and barefooted. The mesiodistal width of the anterior teeth was measured at the contact points; the intercanine and interpremolar widths were measured at the cusp tips from the left to the right quadrant; the arc length was measured at the middle one-third position of the crown from the right to the left canine. Results The results showed that out of the four odontometric parameters, only the arc length was significantly associated with the height of the individuals among the ethnicities chosen. Conclusion Thus, of the four selected parameters, the arc length may be helpful in the estimation of stature among the selected Asian ethnicities. Dimensions of the teeth can be used as an adjunct to other aids in estimating the stature of an individual and hence is a vital forensic tool.
Body height from tooth size: A novel study on stature estimation by odontometric parameters
Introduction: Stature is the height of a person in the upright posture. Based upon the principle that the various long bones correlate positively with stature, stature correlation to skull and jaw dimensions has been frequently reported among various populations. Objective: The study was conducted to investigate the possibility of predicting the height of an individual using selected odontometric parameters as a forensic tool. Materials and Methods: The study sample consisted of 100 randomly selected subjects. Measurements of maxillary intercanine width (IC), maxillary interpremolar width (IP), and mesiodistal width of six permanent maxillary anterior teeth (CW) were made directly on the subject by means of a digital vernier caliper. Height (H) of patients was measured with anthropometer. Results: Significant correlation was observed between height and maxillary IC width (P < 0.05), whereas correlation between height and the combined width of six anterior teeth as well as IP width was found to be nonsignificant. Conclusion: The maxillary IC width can be used successfully to calculate the stature of an individual from fragmentary remains.
