Forensic odontology is the branch of dentistry that deals with dental evidence in legal investigations and proceedings. It helps identify unknown individuals and determine characteristics like age, sex, ethnicity. Teeth can help with identification even after mass disasters due to their hard structure and protection within the body. Dental features are used to estimate age in various stages of life. In children, the development stage of teeth is examined visually or radiographically. In young adults, third molar development is used. In adults, features like tooth wear, secondary dentine deposition, and root translucency are analyzed to estimate age. Forensic odontology plays an important role in legal cases by properly examining and presenting dental evidence.
Dental age can be determined through two methods - stage of eruption and stage of tooth mineralization on radiograph. The stage of eruption method is limited during quiescent eruption periods, while the stage of mineralization method relies on comparing the development of individual teeth to a fixed scale. This second method uses a point system to assess development and calculate a total that correlates to a dental age. It is considered sufficiently accurate when examining teeth 1-7 on the left lower quadrant.
Cephalometrics is the analysis and measurements made on cephalometric radiographs, which are standardized x-rays of the head used in orthodontics. Cephalometrics involves identifying anatomical landmarks, tracing radiographs, and analyzing relationships between craniofacial structures using reference planes and angular and linear measurements. It is an important diagnostic tool for orthodontists to evaluate dental and skeletal abnormalities, plan treatment, and assess treatment outcomes.
Local anaesthesia and exodontia in children is discussed. Key points include:
1. Local anaesthesia works by reversibly interrupting nerve conduction. The most accepted theory is that local anaesthetics bind to sodium channels on nerves, preventing sodium entry and conduction.
2. Techniques for anaesthetizing primary teeth include inferior alveolar nerve block, mental nerve block, infiltration and supraperiosteal injections.
3. Landmarks and techniques may need modification for paediatric patients due to anatomical differences compared to adults.

Radiographic analysis of dental development can be used to estimate age in both living and deceased individuals. Several radiological techniques examine features such as tooth formation, eruption, and root development to determine an approximate age range. Compared to other methods, radiography provides a simple, inexpensive way to estimate age through assessment of dental mineralization stages visible on x-rays. Radiographic indicators are particularly useful for estimating ages of children and adolescents. Combining knowledge of dental development standards with radiological examination allows for multifactorial age determination in forensic cases.

This document discusses forensic pedodontics and child abuse. It notes that child abuse affects an average of 7,200 children per year in India. It defines forensic odontology and discusses the significance of examining dental evidence at crime scenes, such as identifying bite marks and using dental records to identify remains. Newer forensic techniques discussed include DNA fingerprinting, xeroradiography, and UV photography. The role of dentists is also outlined, such as examining and documenting injuries in living abuse victims and aiding in identification and age estimation of deceased children. It stresses the importance of forensic dentistry in establishing justice.
This document summarizes a meta-analysis on the incidence of root resorption after replantation of avulsed teeth. It finds that the incidence of root resorption is high, with replacement root resorption being the most common at 51%, followed by inflammatory root resorption at 23.2% and surface root resorption at 13.3%. Internal root resorption is relatively rare at 1.2%. The studies showed maxillary incisors were most affected and that the risk of different types of root resorption depended on factors like the stage of root development and treatment of the tooth. Limitations included heterogeneity between studies and lack of standardization.
This document discusses a study that assessed awareness and knowledge of forensic odontology among dental professionals in India. The study found that most participants (93.5%) had studied forensic odontology basics in undergraduate studies. However, around 78.4% were unaware of preserving dental records for future forensic needs. While 75.3% understood signs of child abuse and 56.3% could document bite marks, most (77.9%) did not know that dentists can be expert witnesses. The study concludes there is a general lack of forensic odontology knowledge and practice among Indian dental practitioners.
This study analyzed 175 cracked teeth in patients over a 5-year period. The goals were to examine the characteristics and distribution of cracked teeth, evaluate the survival rate of teeth receiving root canal treatment (RCT), and identify prognostic factors. Most cracked teeth were in older patients and located in lower second molars. Intact teeth and those with class I restorations had higher crack incidence. Of the 88 teeth receiving RCT, the 2-year survival rate was 90%. Deeper probing depths (>6mm) were associated with significantly lower survival rates after RCT.
