Maintenance of dental records and awareness of forensic odontology among pakistani dentists: a mixed-method study with implications for dental data repository.

OBJECTIVE: Dental records and forensic odontology play an important role in both healthcare and the legal system, aiding in personalized patient care, human identification, and legal proceedings. This study aims to investigate dental record-keeping practices and assess the awareness of forensic odontology among Pakistani dentists over 12 months. This study aims to collect data from 500 dentists, identify areas for enhancement, and develop a strategic action plan to improve record-keeping quality and forensic odontology application, culminating in a comprehensive dental data repository to support legal and criminal investigations in Pakistan. METHODOLOGY: This study employed a mixed-method approach conducted at Hamdard Dental College from January to March 2023. The quantitative phase involved distributing questionnaires to 463 dentists, chosen through stratified random sampling. Out of these, 413 responded, yielding an 86% response rate. These questionnaires focused on dental record-keeping practices and dentists' awareness of forensic odontology. Subsequently, based on the questionnaire results, face-to-face interviews were conducted with 20 purposively selected dentists to gain deeper insight into the challenges and potential solutions. Data from both phases were integrated and analyzed accordingly. RESULTS: The study included 413 participants, mainly females (79%), with ages ranging from 27 to 65 years and an average age of 46.4 years. Most dentists had 5-20 years of work experience (53%), and most (87.4%) were practicing in private clinical settings. All the dentists generated medical and dental records, but the duration of their record-keeping varied, with some maintaining them for up to a year and others for two years or longer. Five themes were generated from the qualitative content analysis. These themes were dentists' perceptions, barriers and challenges, knowledge and awareness, and improvement strategies. CONCLUSION: Our study revealed that local practitioners in Pakistan exhibit subpar practices in dental record-keeping and maintenance of patient history, irrespective of whether they use a digital or traditional file-based system. Even though dentists are cognizant of the importance of record-keeping, they do not actively maintain comprehensive records. This suggests the need for improved training and system improvements to address the gaps in record-keeping practices.

Morphological Analysis Of Cementoenamel Junction Types In Premolars And Molars Of A Sample Of Pakistani Population.

BACKGROUND: Cementoenamel junction represents the demarcation between enamel covered crown and cementum covered root surface. There is paucity of population specific data of the morphological variability of cementoenamel junctions of permanent and primary teeth. The objective of this study was to investigate the morphological diversity and interrelationship of cementoenamel junction of premolar and molar teeth in permanent dentition of a sample of Pakistani population with potential forensic and anthropological implications. METHODS: This cross-sectional study was conducted at Oral Biology department of Dr Ishrat ul Ebad khan institute of oral health science, Dow University from March till September 2016. Seventy-five maxillary and mandibular permanent premolar and molars from adult patients of both sexes were selected and sectioned. Longitudinal ground sections were prepared to study the morphological interrelationship between Cementum and Enamel in each specimen to be viewed under light microscope. A chi-square test was applied between the categorical variables. RESULTS: Results showed 57.3% of sections had cementum overlapping enamel interrelation, 32% showed edge to edge cementum and enamel relation and 9.3% showed that cementum and enamel failed to meet resulting in exposed dentine, while 1.3% sample showed enamel over cementum relation. No significant correlation was found between gender, type of tooth, maxillary, mandibular arches and the morphological variation of CEJ (p>0.05). CONCLUSIONS: It can be concluded that there are considerable morphological variations in CEJ of premolars and molars with preponderance of cementum overlapping enamel in these teeth. Based on these findings, dentists are advised to be mindful of dental procedures involving the CEJ and that these interventions should be performed meticulously avoiding any detachment of cementum and subsequent exposure of dentin resulting in dentin hypersensitivity.

LOCALIZATION OF THE MANDIBULAR FORAMEN ON THE PANORAMIC RADIOGRAPHS.

BACKGROUND: The mandibular foramen is of particular importance to the dentist and dental specialist as it marks the beginning of the mandibular canal, which transmits inferior alveolar nerve and vessels. The aim of this study was the localization of anteroposterior and superioinferior position of the mandibular foramen on the panoramic radiographs in adolescent and young adult in a selected sample of Pakistani population. METHODS: This cross Sectional study was conducted in the Orthodontic department of Dr Ishrat ul ebad khan institute of oral health science, Dow University Karachi. Material comprised 150 panoramic radiographs. The radiographs were traced on a cellophane sheet. Landmarks were marked and measurements from the centre of the mandibular foramen to other landmarks were recorded. All measurements were recorded to the nearest millimetre. RESULTS: The mandibular foramen occupies the posterior portion of middle third on antero-posterior width of mandible. A ratio between the sides of one or almost one indicated bilateral symmetry. CONCLUSION: The locations of the mandibular foramen occupy the middle third of ramus maintains bilateral symmetry in human mandibles.
