Stress depression and anxiety with xerostomia among young Indian adults.

The relationship of Oral health related quality of life (OHRQOL), stress, depression, anxiety, with xerostomia, un-stimulated salivary flow rate among young Indian adults is of interest. The first phase involved xerostomia along with salivary flow rate measurements. The Depression, Anxiety and Stress Scale (DASS) the standard questionnaire in this field, was used to assess depression, anxiety, and stress in the second part of the study. Xerostomia has a stronger effect on OHRQOL. Anxiety, stress, and depression are examples of psychological factors that significantly impact xerostomia and the reduction of salivary flow rate.

Lip Prints and Dermal Prints as a Tool to Detect the Skeletal Malocclusion: A Clinical Study.

Introduction: For the study's purposes, the researchers are looking to examine if there is a correlation between the skeletal base connection and lip and dermal prints, as well as whether there is a significant variation between genders. Materials and Procedures: Participants in the study numbered 120: Based on Reidel's Malocclusion categorization, There were 40 each of Class I, Class II, and Class III samples. The cellophane technique was used to obtain lip, finger, and palm prints from each of the 120 participants, and the data was analysed using SPSS 22.0. Intergroup comparisons were made using the Chi square test. Atd angle and a-b ridge count were both shown to be statistically significant via the use of an ANOVA test. Class III skeletal malocclusion individuals have a vertical lip pattern, as opposed to the branching lip pattern seen in Class I and II. All three research populations, including the South Indian population, have a right loop pattern. Class I individuals exhibited a greater number of a-b ridges and a greater atd angle. The majority of males and females had branching lip patterns. Conclusion: Dermatoglyphics and cheiloscopy can be used to investigate the genetic correlations of malocclusion and to prevent malocclusion at an early stage. They are simple, affordable, and noninvasive. However, they are not totally dependable because to other ethnic and environmental factors.

DNA profiling and forensic dentistry--a review of the recent concepts and trends.

BACKGROUND: Teeth are amongst the hardest structures of the human body which are resistant to adverse conditions such as incineration, immersion, trauma, mutilation, decomposition and hence, used in forensic investigations. It is also a valuable source of DNA as other parts of the body gets destroyed or degraded in mass disasters. The fast technological advancements in DNA research have revolutionized the field of forensic medicine and the present work was undertaken to provide an insight in to the recent concepts of DNA profiling in Forensic dentistry. METHODS: Articles were identified by searches in PubMed and Embase electronic databases from 1980 through July 2010. RESULTS: DNA profiling provides an exact identification of an individual in mass disasters, identification of culprits in crime scene investigations and solving paternity issues as well. It also provides information regarding the physical characteristics, ethnicity and sex determination. CONCLUSION: Teeth should be considered for DNA analysis as they are rich sources of quality DNA which can be utilised in all forensic investigations. From variable number tandem repeats (VNTRs) to single nucleotide polymorphism (SNP), the field of forensic DNA research has been true to the characteristics of any scientific process and it has never been static but represents a continuous evolution of technological development.
