Assessment of sexual dimorphism using digital orthopantomographs in South Indians.

Introduction: The identification of human skeletal remains plays a crucial role in forensic investigation and its accuracy depends on the available parts of the skeleton. The mandible is the hardest and strongest bone of the skull, which exhibits a high degree of sexual dimorphism and helps to identify the sex in human remains. The aim of this study was to develop discriminant function to determine sex from the mandibular radiographs in a South Indian (Visakhapatnam) population.

Psychosocial factors associated with reverse smoking: A qualitative research.

Objectives: Reverse smoking is a peculiar form of smoking in which the smoker puts the lit end of the cigarette into the mouth and then inhales the smoke. There may be many predisposing factors that influence an individual to cultivate this habit, of which psychosocial habits could be the predominating factor. Hence, the present study was undertaken to evaluate the psychosocial factors that influence an individual to undertake this peculiar habit of reverse smoking.

Clinical efficacy of four interventions in the reduction of dentinal hypersensitivity: A 2-month study.

Background And Aim: Dentinal hypersensitivity is a relatively common problem experienced in clinical dental practice and is characterized by short, sharp pain in response to stimuli such as tactile, thermal, evaporative, osmotic, or chemical. Several agents and treatment modalities have been used in the treatment of this condition. This study was conducted to compare the efficacy of four commercially available toothpastes in the reduction of dentinal hypersensitivity (DH), based on the hypothesis that calcium sodium phosphosilicate (CSPS) group had a better efficacy of the four.

Considering the magnitude of these disorders, an attempt has been made to determine the prevalence and associated factors of various WRMSD.

Mesenchymal chondrosarcoma of mandible.

Mesenchymal chondrosarcomas (MC) are rare and aggressive forms of chondrosarcoma. They are distinct tumors arising in unicentric or multicentric locations from both skeletal and extraskeletal tissues. The most affected region is the facial skeleton, especially the jaws.

Radiographic evaluation of mandibular ramus for gender estimation: Retrospective study.

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.

Malignant Peripheral Nerve Sheath Tumor -A Rare Malignancy in Mandible.

Malignant Peripheral Nerve Sheath Tumor (MPNST) is biologically an aggressive tumor that is usually found in the extremities, trunk and infrequently found in the head and neck area particularly in the jaws, arising from the cells allied with nerve sheath. Mandibular MPNST may either arise from a preexisting neurofibroma or develop de novo. Because of the greater variability from case to case in overall appearance both clinically and histologically, a case of MPNST of the mandible in a 25-year-old female patient is reported.

Langerhans cell histiocytosis revisited: Case report with review.

Langerhans cell histiocytosis (LCH) is a group of idiopathic disorders characterized by proliferation of bone marrow derived Langerhans cells and mature eosinophils. Their clinical features simulate common oral findings such as gingival enlargement, oral ulcers, and mobility of teeth, along with nonspecific radiographic features; hence, diagnosing such lesions becomes difficult for the oral physicians. These lesions are commonly seen in childhood; however, we are reporting a case of LCH in 29-year-old adult male.

Are salivary amylase and pH - Prognostic indicators of cancers?

Background: Saliva, "Mirror of body's health" has long been of particular interest as a substitute for blood for disease diagnosis and monitoring. The radiation effects on salivary glands are of particular interest in which salivary amylase is a good indicator of salivary glands function. Thus, estimation of these parameters represents a reasonable approach in evaluation of patient's risk for disease occurrence, intensity and prognosis.

Is Greulich and Pyle standards of skeletal maturation applicable for age estimation in South Indian Andhra children?

Introduction: Now-a-day age determination has gained importance for various forensic and legal reasons. Skeletal age (SA) of a test population can be estimated by comparing with established standards of Greulich and Pyle (G-P). As this atlas has been prepared using data from upper-class children born between 1917 and 1942 in the USA and the applicability of these standards to contemporary populations has yet to be tested on Andhra children living in India.

Dentigerous Cyst Associated with Adenomatoid Odontogenic Tumour.

Accuracy of four dental age estimation methods in southern Indian children.

Introduction: For various forensic investigations of both living and dead individuals, the knowledge of the actual age or date of birth of the subject is of utmost importance. In recent years, age estimation has gained importance for a variety of reasons, including identifying criminal and legal responsibility, and for many other social events such as birth certificate, marriage, beginning a job, joining the army and retirement. Developing teeth are used to assess maturity and estimate age in number of disciplines; however the accuracy of different methods has not been assessed systematically.

Evaluating the reliability of three different dental age estimation methods in visakhapatnam children.

Unlabelled: Dental age is important for treatment planning in the specialities of pedodontics and orthodontics. Although, Demirjian's method was considered standard for dental age estimation, it may not be reliable for all population.

Aim: The goal of the study was to evaluate the reliability of Demir-jian's, Haavikko's and Willems method of dental age estimation methods in Visakhapatnam (Andhra Pradesh, India) children.

Accuracy of Demirjian's 8 teeth method for age prediction in South Indian children: A comparative study.

Introduction: Demirjian's method of tooth development is most commonly used to assess age in individuals with emerging teeth. However, its application on numerous populations has resulted in wide variations in age estimates and consequent suggestions for the method's adaptation to the local sample. Original Demirjian's method utilized seven mandibular teeth, to which recently third molar is added so that the method can be applied on a wider age group.
