Review literature is a part of the study that the paper from selected journal. This paper aims at determining the oral health knowledge and oral hygiene practices among school children in the study region. This was a descriptive cross sectional study carried out among primary school children. A research administered questionnaire was used to determine the oral health knowledge and practices in a random sample of 401 students in the period March to June, 2002. 92% of the students claimed they brushed their teeth, about 48% brushed at least twice daily. More students (59.1%) reported using chewing stick compared to those using commercial toothbrushes (p = 0.000). Female students brushed more frequently than their male counterparts (p = 0.000, 2 = 24.65). 39.9% of the students knew the cause of tooth decay, 48.2% could state at least one method of prevention, while 16.5% knew the importance of teeth. Use of toothpaste was reported by 38.9% of the students. Less than half of the students knew the causes of tooth decay and how to prevent it. Only about half of the students brushed their teeth twice daily with the chewing stick being more frequently used. Therefore, it was recommended that there is need to increase the oral health knowledge through well planned school based oral health education programmes in the primary schools. This would hopefully lead to improvement on the oral hygiene practices
 

In order to handle forensic dental evidence and provide a report to a court of law, forensic odontology is a subdiscipline of dental science that employs a multidisciplinary approach. Dental science and forensic odontology are progressively gaining in prominence and applicability in the judicial system. In forensic casework of human identity, age estimation, and sexual assault cases with patterned injuries, there is a requirement for a specialist forensic kit by legal and forensic authorities.
The forensic kit contents should be in accordance of the crime scene whether indoor or outdoor. To handle the evidence, a set of armamentarium/equipment related to forensic odontology are needed for a specific purpose based on the place of application. This article is an attempt to provide a comprehensive review of the essential equipment needed in a Forensic Dental Kit at the crime scene for investigation by a forensic odontologist, which will aid in the collection of evidence, the transfer and maintenance of records, and the identification of the perpetrator.
 

Background:
Introduction: Radiographs have been widely used to determine morphological traits among genders in forensic odontology.
Aim: The study aims to determine the gender using an occlusal radiograph.
Objectives: Assessing the reliability of linear and angular measurement in the occlusal radiograph.
Materials & Methods: The study was conducted in the Department of Oral Medicine & Radiology in Namakkal District, after obtained approval from the institutional ethical committee with total sample size of 40 dentate subjects using an occlusal radiograph. After obtaining informed consent from patients, the study has been conducted.
Topographic occlusal radiographs were taken with help of an intraoral X-ray machine with ideal exposure parameters and all radiation protective precautions were carried out. Linear & angular measurement are measured attributing capital letters to the maxillary arch & small letters to the mandibular arch.
Statistical Analysis: The obtained data were analyzed using student t-test & Spss software version 22.0.
Results: In the present study among linear measurement molar (MM) is highly significant (p=0.012.) Among Angular measurements max CIA R (p=0.001), max PIB R (p=0.001), max MIC R (p=0.007), man pib r (p=0.017), man mic r (p=0.031), man pib l (p=0.028) are highly significant.
Conclusion: Gender can be determined by occlusal radiographs with greater reliability when linear measurement & angular measurements are performed.
