Objetivo: Describir el uso de las modalidades diagnosticas pertenecientes a la imagenología dentofacial en la odontología forense. Materiales y métodos: Se realizo una búsqueda en la base de datos de PubMed, Google Académico y SciELO con las palabras clave “Dentofacial imaging”, “Panoramic Radiography”, “Lateral Cephalogram”, “Cone Beam Computed Tomography (CBCT)”, “Digital Radiography”, y “Forensic Dentistry”. Se seleccionaron 48 artículos publicados en ingles, de fechas recientes, buscando información que describiera el uso de las modalidades diagnosticas pertenecientes a la imagenología dentofacial en la odontología forense. Resultados: Las modalidades diagnosticas de la imagenología dentofacial incluyen dentro de las más relevantes para la odontología forense la radiografía panorámica, la radiografía lateral de cráneo, la radiografía posterioanterior de cráneo y la tomografía computarizada de haz cónico. Conclusiones: Estas modalidades, junto a la ejecución de análisis morfométricos, permiten al odontólogo forense la identificación de un cadáver, la estimación de la edad, el sexo e incluso la reconstrucción facial forense con fines identificativos.

“…The mandibular bone is the strongest and hardest bone which does not easily decompose after death. [ 32 33 34 ] The mandible in the head and neck area being the most prominent bone is subjected to trauma more frequently in the facial skeleton, in case of any major accidents or disasters. In majority of cases, trauma occurs in the condyle region (36%), followed by body (21%), angle (20%) and symphysis (14%).…”

Background:In recent years, the techniques used to identify human remains post accidents, trauma or in case of criminal investigation have been expanded, improved and rendered more complex by the emergence of technologies based on deoxyribonucleic acid (DNA) analysis. In the head and neck area, tooth has been proven to be the best quantitative source for DNA but in certain cases where the mandible specimen is edentulous or the tooth is extensively destroyed with caries, large dental restorations, mobile, or if they show any perimortem or postmortem fractures, sampling of such tooth specimen is usually avoided. In such situations, bone is considered the next best site for DNA analysis. Mandible being the largest, strongest and dense cortical bone is the most prominent facial bone that can be easily disarticulated. It can be analyzed for the best short tandem repeat (STR) segment qualitative amplification using polymerase chain reaction (PCR) technique for forensic analysis which can be used for gender and age determination.Aim:The aim of this study is to determine the best site for optimum quantitative and qualitative yield of DNA for amplification using specific and standard STR segment by conventional PCR technique.Methodology:Fifteen mandibular samples exposed to different environmental conditions were collected. Bone pieces of 1 cm × 1 cm were cut from each mandible from three sites, i.e., the ramus, angle and body, wherein the genomic DNA was isolated and was subjected to PCR using restricted number of 25 cycles.Results:The STR segment D3S1358 from clone RP11-438F9 used for the study showed very good amplification in restricted number of PCR cycles in the ramus region with number of repeats in every 15th genomic region.Conclusion:This study highlights the use of mandibular bone for the expeditive human identification. As per the study, the ramus of the mandible gave high quantitative and qualitative yield of DNA with thick amplification band of the STR segment as compared to the body and angle of the mandible. Thus ramus of the mandible can be preferred over other sites for molecular forensic investigations.

“…A study performed by Ishwar Kumar et al [7] in South Africa concluded that the length of the mandibular ramus generally has higher sexual dimorphism than any other mandibular segments (P-value=0.000). The authors found that only the length of the right mandibular body differed significantly according to sex (P-value=0.040).…”

“…The mandible shows morphological changes related to size and remodeling during human growth. It has been found that there is a strong correlation between chronological age and mandible morphology, especially that of the ramus [7] . Additionally, ancestry and genetic factors are believed to modify bone age validation for chronological age determination.…”

Background: The determination of age and sex is crucial for establishing human identity. The mandible is an accessible and durable bone that is very useful in this respect. Aim:To assess the efficacy of measuring the mandible ramus length in the identification of age and sex in a group of Egyptians. Subjects and Methods:The length of the ramus of the mandible was measured in lateral craniofacial scans of 213 individuals (99 males and 114 females) with an age range of 7-58 years using cone-beam computerized tomography (CBCT). Results:Sexual dimorphism was not observed until age of 17 years in this sample. There was not found any significant differences in the length of the ramus of the mandible between males and females in the age range of 7 to less than 17 years (P-value = 0.2495). There was a significant difference between males and females for the mean length of the ramus in the age range of 17 to 58 years (P-value < 0.0000). It predicts sex with an accuracy of 67%. There was a positive correlation between and (age) and log e (ramus length) (r=0.73, P-value < 0.0001 for females and r=0.85, P-value <0.0001 for males). Therefore, it was possible to calculate each individual's age based on his or her mandible ramus length. Conclusion:The mandibular ramus length is valuable in age estimation and less valuable in sex determination. Computerized tomography examination is a safe and an accurate procedure with minimal radiation exposure, and provides valuable precise information regarding mandible measurements.
