INTRODUCTION: Age estimation is important for administrative and ethical reasons and also because of legal consequences. Dental pulp undergoes regression in size with increasing age due to secondary dentin deposition and can be used as a parameter of age estimation even beyond 25 years of age. Kvaal et al. developed a method for chronological age estimation based on the pulp size using periapical dental radiographs. There is a need for testing this method of age estimation in the Indian population using simple tools like digital imaging on living individuals not requiring extraction of teeth...

INTRODUCTION: Conventional methods to estimate the time of death are adequate, but a histological method is yet unavailable to assess postmortem interval (PMI). The autolytic changes that occur in an unfixed antemortem gingival tissue which reflects histologically at an early stage are similar to changes that occur in postmortem tissue. These histological changes can be used and applied in a postmortem tissue as a method to assess PMI. AIMS: The aim of the study is to assess the histological changes in a gingival tissue left unfixed for various time intervals and to correlate the findings with duration...

INTRODUCTION: The role of a dentist is not only to examine and treat the oral diseases but also to assist the legal authorities by means of its branch-forensic odontology. Through forensic odontology, a dentist plays a very important role in crime investigation of any type. OBJECTIVE: To analyze the knowledge, awareness, and interest of forensic odontology among the dental teaching staff who are working in the dental colleges within the Delhi NCR. MATERIALS AND METHODS: A questionnaire of 12 questions (both open-ended and close-ended) was prepared and the survey was conducted with 200 dental teaching staff...

CONTEXT: Estimation of time passed since death continues to be a major problem for the forensic pathologist and its determination plays an important and vital role in medico-legal cases. The histological studies on various tissues after death have been mostly confined to single organ or tissue by individual workers at different atmospheric conditions. AIMS: The aim of this study is to determine the best rehydrating solution for dehydrated tissues in postmortem examination...

BACKGROUND: The Ricketts' posteroanterior (PA) cephalometry seems to be the most widely used and it has not been tested by multivariate statistics for sex determination. OBJECTIVE: The objective was to determine the applicability of Ricketts' PA cephalometry for sex determination using the logistic regression analysis. MATERIALS AND METHODS: The logistic models were estimated at distinct age cutoffs (all ages, 11 years, 13 years, and 15 years) in a database from 1,296 Hispano American Peruvians between 5 years and 44 years of age...

BACKGROUND: Stature is considered to be one of the "big fours" in forensic anthropology. Though Carrea's Index was published as early as 1920 it has not been validated in any other population apart from the Brazilians. AIM: The present study was conducted to validate Carrea's index in stature estimation in two different racial populations in India. MATERIALS AND METHODS: The study was carried out in a sample of 100 persons comprising of 25 Aryan males, 25 Aryan females, 25 Dravidian males, and 25 Dravidian females in the age group of 18-30 years...

CONTEXT: Thermal insult is the major cause of thermal injury or death and in case of death due to thermal injury the body often has to be recovered from the site. Histologically, one can predict whether the victim was alive or dead when the fire was on going. However, determination of probable cause of thermal insult to which victim subjected to be difficult when the victim's body is found somewhere else from the crime scene or accident site or found alone. Hence, histopathological evaluation of the tissue which has undergone thermal insult in such conditions could help to place evidence in front of law officials, regarding probable condition, or scenario at time of burn of victim...

Identification of humans, especially in mass disaster is a challenging aspect for team members of the disaster victim identification (DVI) unit. Identification is necessary for humanitarian and emotional reasons and for many legal issues, particularly for family members. In the modern day, all possible methods have been applied for establishing the identification of deceased individuals. The DVI team comprises specialists from different disciplines. The forensic dentist plays a major role in the identification of victims in disaster...

INTRODUCTION: Sex determination is a vital step in reconstructing an individual profile from unidentified skeletal remnants. Variations in tooth size are influenced by genetic and environmental factors. Tooth size variations have been reported among different populations. AIM: To identify the sex by determining the mesiodistal (MD) dimensions of maxillary canines. OBJECTIVES: (1) To compare the MD diameter of all maxillary canines - (a) in the entire urban and tribal population, (b) in urban male and urban female populations, (c) in tribal male and tribal female populations, and (d) in the entire male and female populations and (2) To estimate the percentage of sexual dimorphism individually in urban and tribal populations...

BACKGROUND: All humans have an identity in life; compassionate societies require this identity to be recognized even after death. OBJECTIVES: To measure the dimensions of the mandibular canine and assess the usefulness of the mandibular canine as an aid in gender estimation. MATERIALS AND METHODS: The study population comprised 200 subjects inclusive of 100 males and 100 females with an age range of 18-25 years. Measurements made in mm at the contact point were of mesiodistal width of the right and left canines and intercanine distance both intraorally and on casts, and the mandibular canine index (MCI) was calculated...

BACKGROUND AND AIMS: Gender estimation is a very important part of a study in the field of anthropology and forensic sciences. In the skeleton, gender estimation is the first step of the identification process as subsequent methods for age and stature estimation are sex-dependent. Skeletal components such as the pelvis and skull are investigated for gender estimation and the mandible is a practical element to analyze sexual dimorphism in fragmented bones. The aim of the present study is to measure, compare, and evaluate various measurements of the mandibular ramus, observed in digital orthopantomographs and also to assess the usefulness of the mandibular ramus as an aid in gender estimation...

CONTEXT: Morphological variation in children can be understood by the knowledge of growth and development. The state of dental development can be used in forensic odontology to ascertain the age of an unidentified child. AIMS: This study aims to investigate the relationship of the stages of calcification of the permanent mandibular canine, mandibular premolars, and permanent mandibular first and second molars with skeletal maturity using panoramic and hand-wrist radiographs...

Deaths during dental treatment or as a result of dental treatment are rare, but the unfortunate fact is that such deaths do occur. Unexpected death of a patient can be emotionally draining and even harrowing to his or her relatives. The death of a patient may bring an enormous feeling of anxiety both at the personal and professional level, stress, profound grief, damage to self-esteem, loss of self-confidence, reputation, and specter of litigation on a dental surgeon. No dentist can be guaranteed to be free of such an incident during the course of his or her practice...

BACKGROUND: The palatal rugae are the ridges situated in the anterior part of the palatal mucosa, are unique to each individual, and can establish individual's identity. AIMS: To establish the reliability of using the palatal rugae dimensions in identifying the different ethnic groups. SETTINGS AND DESIGN: Many studies have established the reliability of using the palatal rugae patterns in identifying the different ethnic groups. However, no studies have been reported in the English language literature that uses the rugae dimensions to identify the different ethnic groups...
