Introduction: The lingula is used for identifying the site for injection of local anesthetics and for excision of nerve in facial neuralgia. The relationship between lingula and lingual nerves may aid in risk associated with an impacted third molar. Due to its connection to nerve and vascular structures, the study of the lingula provides important information related to oral and maxillofacial surgical procedures, such as the sagittal split ramus osteotomy and the intraoral vertico-sagittal ramus osteotomy carried out to correct dento facial deformities...

BACKGROUND: Maturation is the irreversible biological process leading to adult form or function. The degree of maturation can be derived from the examination of maturity indicators, i.e. of particular aspects of the overall maturation, such as pubertal status, skeletal and dental morphology. Rhythm of maturation of each indicator differs between populations and individuals, because of genetic, nutritional and environmental factors. Skeletal maturation is usually expressed as skeletal age, which is the median age at which a given degree of maturation is attained...

BACKGROUND: Identification of unknown dead bodies' especially bony remains is done by different methods like DNA typing, Finger printing, Dental and other skeletal data, facial reconstruction and rugae pattern study. Palatal rugae pattern study or Ruguscopy gives a unique method of identification in cases of skeletal remains due to its uniqueness, resistance to heat, and stability throughout life. METHODS: This simple random sampling was carried out on 102 study models (casts of palate) of patients having 880 rugae patterns above 20 years of age in Khan Dental Clinic near Ayub Medical College, Abbottabad...

BACKGROUND Dental age is less affected than the bone age by nutritional and hormonal factors. The assessment of dental age in children is of value in clinical and forensic practice. The aims of this study were to compare the Demirjian method and the Willems method in the assessment of dental age in children in Poland and to consider the need to standardize dental age assessment. MATERIAL AND METHODS Polish children of Caucasian ethnicity (n=1,002) who were treated at a single orthodontic center between 1994-2016 included girls (n-540) and boys (n=462) aged between 4-17 years, and 1,002 panoramic radiographs were reviewed...

The estimation of age in living subjects is today a significant issue because of the increase in the situations in which it arises and its legal consequences. In line with the Study Group on Forensic Age Diagnostics of the German Association of Legal Medicine's recommendations, it is based on the concomitant use of physical examination and methods for estimating bone age and dental age. Given the variations between the populations, the use of the latter requires their validation on all the ethnic groups on which they can be used...

Background: Bite mark analysis is an imperative area of forensic odontology and considered the commonest form of dental evidence presented in the criminal court. The process of comparing bite marks with a suspect's dentition includes analysis and measurement of shape, size, and position of an individual's teeth. The present study was aimed to evaluate the bite marks of males and females using a novel indirect computer-assisted method and explicate its application in forensic odontology...

Dental development is one of the most widely utilized and accurate methods available for estimating age in subadult skeletal remains. The timing of tooth growth and development is regulated by genetics and less affected by external factors, allowing reliable estimates of chronological age. Traditional methodology focuses on comparing tooth developmental scores to corresponding age charts. Using the Moorrees, Fanning, and Hunt (MFH) developmental scores, Shackelford and colleagues embed the dental development method in a statistical framework based on transition analysis...

Understanding dental maturation in ethnically distinct populations is important in forensic age estimations and the presence of population differences in dental maturation was highly debated. No such comparison had been performed between two major populations; Caucasian and Chinese. This study aims to analyze and compare the maturation of permanent teeth from a sample of Caucasian and Chinese populations. Dental panoramic radiographs of subjects aged 2-24years belonging to United Kingdom (UK) Caucasian and Hong Kong (HK) Chinese populations were obtained from a teaching hospital...

The goal of this project is to validate the Cameriere's method applied to the upper and lower second premolars in a Portuguese population, regarding the forensic estimate of age. The applied sample consisted in 100 panoramic radiographs, of 60 males and 40 females, patients of the Faculty of Dental Medicine of the University of Lisbon, whose ages vary between 15 and 35 years old. Thus, a total of 400 teeth were investigated (200 upper second premolars and 200 lower second premolars). Each radiograph was analysed using draw and measurement tools featured in Adobe Photoshop, applying the Cameriere's method, and then the pulp/tooth ratio was computed for the 15, 25, 35 and 45 teeth...

Collection for touch DNA either at scenes or on items submitted to a forensic laboratory is based on assumptions as to where a person made direct contact. In many instances a swab may be applied to an area where no contact has been made. Many swabs may therefore be submitted for DNA profiling on which no DNA is present, resulting in the loss of both time and resources by analysing such swabs. This study has developed a simple, fast, DNA-staining and fluorescence microscopy-based screening method for swabs to indicate if there is any DNA from which to generate a profile...

Forensic thanatology comprises the investigation of every phenomenon related to death performed through cadaveric exams. The pink tooth phenomenon (PTP) emerges as a thanatological finding registered during medical or dental autopsy. The PTP consists of a reddish or pink coloration caused in the teeth by the penetration of pulpal hemoglobin in the dentinal tubules. Initially, the PTP was associated with specific violent deaths, such as drowning, hanging and poisoning. However, scientific reports have pointed towards the occurrence of PTP as an expression of cadaveric decomposition regardless of the cause of death...

The assessment of skeletal age is of utmost importance not only in the field of anthropology, forensic medicine, pediatrics, endocrinology but also in orthodontics and jaw orthopedics. Bone age refers to the individual's biological development which can differ within a relatively wide range for the same chronological age. Therefore, accurate assessment of skeletal maturity and pubertal growth plays an important role in establishing a diagnosis for certain diseases. In addition, it is essential for proper timing and success of treatments in many cases...

With an alarming increase in number of juveniles in conflict with the law, in India as well as worldwide, more emphasis lies on radiographic dental age estimation (DAE) methods for different ethnic populations having specific formulas based on large sample databases. Of these, Chaillet and Demirjian modification of original Demirjian method was devised to increase the applicability to 18-year-old individuals. However, this method is cumbersome with multiple tables and difficulty in comprehension, thus deterring its use on a wider scale...
