“…These size-correlated aspects of MS While the results of our Procrustes-based analyses provide readily interpretable visualization of size-correlated differences in relative MS shape, the results of our analyses of linear measurements provide important insights into the absolute directionality and magnitude of these scaling relationships. As found by numerous previous studies (Akhlaghi et al, 2017;Amin & Hassan, 2012;Butaric, 2013;Fernandes, 2004a;Paknahad et al, 2017;Sahlstrand-Johnson et al, 2011;Teixeira et al, 2020;Teke et al, 2007;Tillier, 1977), our study found anteroposterior length to consistently be the largest dimension of the MS, followed in magnitude by superoinferior height, and mediolateral width. Yet, despite being the largest linear dimension, we also found MS length exhibited relatively little variation across the sample or within each subsample.…”

“…Alternatively, a number of studies employing computed tomography (CT) scans have assessed the dimensions (i.e., height, width, length) of the sinus (Akhlaghi et al, 2017; Amin & Hassan, 2012; Evteev & Grosheva, 2019; Fernandes, 2004a; Paknahad et al, 2017; Sahlstrand‐Johnson et al, 2011; Teixeira et al, 2020; Teke et al, 2007). Although these studies have differed slightly in measurement protocols, these studies have generally found anteroposterior length to be the largest MS dimension, followed by superoinferior height, and mediolateral width as the smallest dimension.…”

Objectives: Although research into human maxillary sinus (MS) morphology has overwhelmingly focused on sinus volume, other aspects of morphology (e.g., overall shape, mucosal surface area) factor prominently in hypotheses regarding MS form and function. Here, we investigate MS volume in conjunction with measures of MS shape and surface area in a large, diverse sample of modern humans. We test whether variation in MS volume is associated with predictable changes in MS shape (i.e., allometry) and investigate the influence of MS size-shape scaling on mucosal surface area dynamics.Materials and Methods: Measures of MS volume and surface area were obtained from computed tomographic (CT) scans of 162 modern human crania from three ancestral backgrounds-Equatorial Africa, Europe, and East Asia. 3D coordinate landmarks and linear measurements were also collected. Multivariate analyses were employed to test for associations between MS volume and other morphological variables.Results: Significant associations between MS volume and 3D shape were identified both across and within the subsamples. Variation in MS volume was found to predominantly relate to differences in MS height and width dimensions relative to MS length. This pattern of allometric scaling was found to differentially influence total mucosal surface area and the SAV ratio. Conclusion:This study suggests that variation in MS volume is disproportionately mediated by MS width and height dimensions. This finding has implications for hypotheses which structurally link MS morphology to craniofacial ontogeny and those which suggest that MS morphology may perform adaptive physiological functions.

“…The best discriminating factor was height of maxillary sinus that was lesser in value in females than in males. 13 CBCT has been frequently used to screen the disease and pathological processes. 14. A study conducted in Iran found out a contrasting difference between height and length of maxillary sinuses though it was reported that sexual dimorphism does not exist while comparing width of maxillary sinuses 15 .…”

Aim: To determine gender through digital radiography from the height and width of maxillary sinus. Study Design: Descriptive study. Place and duration of study: Kuwait Teaching Hospital and Khyber Teaching Hospital Peshawar from 1st January 2020 to 30th June 2020. Methodology: AP view of radiographs of 64 female participants was used and analysis of morphological parameters of maxillary sinus was done by using microdicom software. Results: The mean height and width of right maxillary sinus was 22.39mm and 22.54mm respectively while the mean height and width of left maxillary sinus was 22.39mm and 20.81mm respectively and was found to be statistically highly significant. Conclusion: Determination of female gender can be done with the help of anteroposterior view of digital radiographs from the height and breadth of maxillary sinuses. Key words: Gender determination, Forensic radiography, Female, Sexual dimorphism, Maxillary sinus

“…Okkesim and Sezen Erhamza [22] reported a significant difference in mandibles among genders using CBCT images. In addition, Teixeira et al [23] indicated that CBCT images showed that males had greater values for the length, breadth, and height measures of their maxillary sinuses, with the height of the sinus being the best indicator of sexual determination. Urooge and Patil [24] evaluated the CBCT of the maxillary sinus and reported that the efficiency of maxillary sinuses in sex identification was 74% in females and 68% in males.…”

The Role of an Endodontist in Victim Identification: A Narrative Review on Forensic Endodontics

This narrative review highlights the role of endodontists and the significance of various dental tools in forensic dentistry. An online search was conducted in peer-reviewed journals, including MEDLINE (Ovid), PubMed, Web of Science, Scopus, and Google Scholar databases, to retrieve studies regarding "the role of an endodontist in victim identification using different tools". The searches used controlled vocabulary and freetext terms. Articles written in English and published from 1923 to 2023 were selected. An essential stage in forensic dentistry is dental identification of the dead person and is regarded as an initial step for both judicial and humanitarian purposes if fingerprint records are missing or the remains have undergone significant changes. Endodontists should be aware of all available dental tools that aid in identification. The four fundamental tools for identification are dental radiographs, hard and soft dental structures, and dental materials. Dental radiographs provide a substantial nondestructive record for estimating age and sex. Moreover, maxillofacial hard and soft structures provide important tools for individual identification as they are considered the strongest structures in the human body and can withstand severe chemical and temperature changes. In addition, endodontic and restorative materials can be identified under different conditions and serve as excellent forensic identification measures.
