Background: An obstacle in forensic odontology is an incomplete body caused by post-mortem damage. The problem can be solved by using lateral cephalometric radiographs for victim identification. Sex determination can be performed on the maxillary sinus, which is the largest among the paranasal sinuses. Purpose: This study aims to analyse the maxillary sinuses’ width and height on lateral cephalometric radiographs among male and female subjects. Methods: The study samples were 60 lateral cephalometric radiographs (30 males and 30 females) between the ages of 20 and 40, with complete permanent dentition (or third molar absence). The height and the width of maxillary sinus measurement were performed using measurement tools of EzDent-i Vatech Software. Results: The average width of the maxillary sinus on males was 40.60 ± 1.56 mm, and the height was 35.02 ± 2.09 mm, while the width and the height on females were 36.93 ± 1.30 mm and 29.72 ± 1.76 mm, respectively. The independent t-test reveals a significant difference (p<0.05) between males and females, both in the maxillary sinus’s width and height on the lateral cephalometric radiograph. Conclusion: The maxillary sinus in males is larger than in females, it opening up possibilities for disaster victim identification.

Abstract Background and aims: Maxillary sinuses are the largest of the paranasal sinuses known for variability in their dimensions. The maxillary sinus dimensions can be better ascertained in living by using computed tomography instead of plain radiography. This study was planned for highlighting the variations in the dimensions of the maxillary sinuses of population of Tamil Nadu region. The aims of the present study were to estimate dimensions of the maxillary sinuses on computed tomographic (CT) scan of the head of patients from Tamil Nadu and to compare the data gender wise and sidewise. Material and methods: Maximum width, height and depth of maxillary sinus of both sides were measured in CT - head images of 100 males and 100 females of 20-50 years of age in Tamil Nadu. Comparison of data between genders and sides by applying unpaired student "t" test was done. Results : The mean depth, height and width of both right and left maxillary sinuses were comparatively less in females than the males and the difference was found to be statistically significant ( P <.0001). On comparison between the sides of maxillary sinuses, the depth and the height of maxillary sinus did not show any significant difference in the measurements (p >.05), whereas the width of the left side (23.96 mm) was higher than that of the right side (23.69) and the difference was found to be statistically significant (P<.05). The combined average maxillary sinus dimensions (in mm) for both genders in the study population of Tamil Nadu are as follows: Right side depth: 33.71 ± 1.00; Left side depth : 33.65 ± 1.22; Right side height: 34.66 ± 2.71; Left side height: 34.74± 2.48; Right side width: 23.69 ± 0.78 and Left side width: 23.96 ± 0.86. Conclusion: The dimensions of maxillary sinuses in males were found to be larger than those of females and this difference was statistically significant. The average width of the maxillary sinuses on the left side is significantly more than that of right sided sinuses. Computed tomography measurements of maxillary sinuses may be useful in gender determination.

Identification of victims in a disaster is a challenging process and requires use of both primary and secondary identifiers. Development of teeth is one of the routinely used methods of age estimation and helps in establishing deceased biological profile. Two children who lost their lives in 2014 in Nepal Airlines crash, were looked for the dental developmental status. One of the children had primary dentition, while the other had mixed dentition. This helped us in estimating age of these individuals reconciled with the chronological age provided by the relatives. This led to the identification of both the children, thus, emphasizing teeth as important means of identification in any disaster.

OBJECTIVES: To determine the correlation between chronological age (CA) and mandibular third molar (MTM) development in a sample of Khyber Pakhtunkhwa (KP) population. Furthermore, to provide forensic reference data for age determination from MTM mineralisation. Finally, to derive regression formulae specific to this population to estimate age using MTM calcification stages. METHODOLOGY: Four hundred and seventy orthopantomographs (OPGs) of patients aged between 13-26 years from the Orthodontics department archive at the main tertiary dental hospital of KP were studied for development of MTM staging using Demirjian's method. Spearman's Correlation was applied to determine any relationship between CA and MTM development. An Independent two-sample t-test was performed to compare third-molar development in males and females. Population-specific models was developed using quantile regression analysis. RESULTS: A strong positive correlation was found between CA and MTM development (rs = 0.853; p- <0.001). The median quantile regression equation developed for entire sample is: Age = 8.8+ 1.4(developmental stage). Ninety-four percent of males and females at stage H were at least 18 years or older. CONCLUSION: Mandibular third-molars can be an appropriate guide for CA estimation in the KP population. Stage H is likely to occur at 18 years of age. This may be valuable for medicolegal suits requiring CA estimation.

Purpose. Radiography is important in forensic odontology for the identification of humans. The maxillary sinus is the largest of the paranasal sinuses and first to develop. Sinus radiography has been used for identification of skeletal remains and determination of gender. Hence, the aim and objectives of the present study were to establish a new method for gender determination using maxillary sinus index from lateral cephalometric radiographs and to establish the reliability of maxillary sinus for gender determination. Methods. A total of 50 adult digital lateral cephalometric radiographs (25 males and 25 females) were included in the study. The maxillary sinus analysis was performed on these radiographs using the height and width measurement tools of Sidexis XG software. Maxillary sinus index was calculated, discriminant function analysis performed, and discriminant equation derived for determination of gender. Results. The mean maxillary sinus height and width were found to be higher in males, whereas the maxillary sinus index was greater in females. The discriminant function analysis derived in the study was able to differentiate the sex groups with sensitivity of 68% and specificity of 76%. Conclusions. From the results of the present study, it may be concluded that morphometric analysis of maxillary sinus can be used as a reliable tool in gender determination.

Introduction: The palatal rugae are anatomical folds or wrinkles located on the anterior third of the palate behind the incisive papilla on each side of the palatal raphe. The rugae patterns have been studied for various purposes mainly in the field of anthropology, comparative anatomy, genetics, prosthodontics, orthodontics and forensic odontology. This study is aimed to determine the difference in number and pattern of palatal rugae in males and females. Methods: This is a prospective study in which maxillary impressions of 50 volunteers, 25 males and 25 females were taken and the casts prepared. The boundaries of the rugae were marked with a HB pencil and were observed with a magnifying glass following the classification used by Kapali, et al, (1997). Association between rugae number and sex and rugae shape and sex were tested using two sample unpaired t test. Results: The study revealed significant difference in the pattern of converge rugae which were found to be higher in females than males, however, no statistical significant difference was found in the number of rugae between the two sexes. Conclusions: The rugae pattern can be an additional method of differentiation between the males and females in conjunction with the other methods used in forensic sciences.

Forensic odontology in dentistry is used to identify victims. Several methods can be used, such as rugoscopy. Rugoscopy is a victim identification method by evaluating the palatal rugae. Rugoscopy is very advantageous due to its low cost, fast results and practical nature. Palatal rugae is protected from trauma and high temperature due to its internal position in the oral cavity. Palatal rugae is an individualistic structure, though it bears several resemblance with the hereditary pattern due to the polygenic mechanism. The purpose of this research is to determine the difference of palatal rugae shape and size between uncle and nephew in Minangkabau ethnics. This study is an analytical observational study with a cross sectional approach. A total of 78 pairs of uncle and nephew of the Minangkabau ethnicity in Luhak Nan Tigo. Palatal rugae is classified using the Thomaz and Khutze classification. Data were analyzed by using Mann Whitney non-parametric statistical analysis. Data analysis show the palatal rugae shape of uncle and nephew from the Minangkabau ethnicity is dominated by a wavy shape, followed by curvy, straight, unified and circular shapes. The palatal rugae size of uncle and naphew from the Minangkabau ethnicity is dominated by primary size, followed by secondary and fragmenter size. Mann Whitney analysis revealed no significant difference of palatal rugae shape and size between uncle and nephew in Minangkabau ethnics (p>0,05), though there is a significant difference in the unified shape (p<0,05). Palatal rugae shape and size have a similar pattern with hereditery patterns, though not identical. Palatal rugae may be used as a secondary method of victim identification Keywords : Rugoscopy, palatal rugae, uncle and nephew

INTRODUCTION: Corpse recognition is a difficult procedure. Comparison of both ante mortem and post-mortem records is essential and assists in identification of corpses. Typical methods of identification however sometimes may be inconclusive. Gender determination is an important aspect in identification of corpses. Previously skull, pelvis and the long bones have been used in gender determination. It has been reported earlier that maxillary sinus remains intact even when skull and long bones may be badly disfigured in incarnated victims.AIM: The aim of this study was to examine whether the measurements of the maxillary sinuses may possibly be used for gender determination.MATERIAL AND METHODS: Computed tomography scans of total of 50 Adults patients within the age range of 25 to 65 years from the previous dental records were taken. Sample comprised of 25 (50%) males and 25 (50%) females. The width, height and length was measured in all cases using CT images.RESULTS: Maxillary sinus exhibits anatomic variability between genders. A significant difference in the length and height of maxillary sinus was observed with respect to males and females. (p<0.005)CONCLUSION: We conclude from the present study that the height and length of maxillary sinuses together with other bones can be used for gender determination when skeleton is not available.
