Background: The age estimation of the individual by the forensic experts ascertains the chronological age of an individual. The possibility that the person being examined may be younger or older than a certain age threshold makes this process crucial, as it will establish whether or not the person is an adult under the law. The aim of this study was to test the applicability of the London Atlas of tooth development and eruption in Nepalese subset population.

Two onboard crew members lost their lives in the fatal Makalu Air Cessna Grand Caravan 208B domestic cargo flight crash on May 16, 2018. The Disaster Victim Identification (DVI) procedure comprises external examination, photography, DNA collection, fingerprint collection, postmortem examination, antemortem information collection from the family members, and reconciliation. The major challenge of this operation was dealing with cognitive bias.

Introduction: Mandibular condyle is a prominent structure in the mandible, which forms the temporomandibular joint. An oval-shaped condyle is considered to be present with a normal temporomandibular joint and any morphological variation of the condyle is assumed to be pathologic in temporomandibular disorders. The aim of the study was to find out the prevalence of oval shaped mandibular condyle among orthopantomogram radiographs of patients visiting the tertiary care centre.

Objective: The shape of the condyle, coronoid, and the intervening sigmoid notch is unique due to attachments and direction of pull of temporalis muscle, different chewing habits, hormones, etc. So morphometric variation of these mandibular landmarks can be used in individual identification.

Material And Methods: The study was carried out on 500 panoramic view images.

The aim of this systematic review was to find out if manual intraoperative control of occlusion is adequate for the reduction of mandibular fractures in comparison with intermaxillary fixation (IMF). We searched PubMed, Embase, the Cochrane Library and Clinical Trials Registry, and the references of included trials. Our primary outcomes of interest were the reduction of fracture anatomically and radiographically, occlusal disturbances, and the incidence of revision procedures due to poor occlusion or reduction.

Background: Age estimation is an integral tool in identification of the victims when visual identification is not possible. Secondary dentin deposition is a regular ageing process and can be utilized in dental age estimation when development and eruption parameters cannot be utilized.

Methods: In total, 38 monoradicular teeth of Nepalese subjects were assessed for tooth pulp ratio.

Introduction: Age estimation is an important aspect in forensic anthropology, as it can aid in the identification of the deceased, and can be used in cases of immigration, child abuse and criminal prosecution in living individuals. Dental age estimation is considered reliable and accurate, since tooth development is least affected by environmental factors compared to somatic growth.

Methods: In total, 150 pre-orthodontic treatment radiographs from healthy individuals were assessed.
