Do residential care and low social capital negatively influence oral health-related quality of life (OHRQoL) among older adults? A cross-sectional study.

Objectives: To compare oral health status, OHRQoL and social capital between dependent older adults living in a residential care setting (RC) and community dwellers living independently (CD) and to assess the possible role of social capital and residential status as independent predictors of OHRQoL in a sample of older adults in the Udupi region of Karnataka, South India.

Background: As the global population ages, a greater number of older adults are now living in residential care settings than ever before. This study provides insights into the role of residential care and social capital in influencing the oral health-related quality of life (OHRQoL) among older adults.

Publication analysis in Bay for Bengal Initiative for Multi-Sectoral Technical and Economic Cooperation Nations.

Research output provides an insight into the development of the scientific capability of a country. Budget allocation for research and development (R&D) is directly proportional to the research output of a country. While developed countries spend a significant percentage of their GDP on R&D, developing countries do not have enough resources to invest in R&D.

Oral health surveillance in Australia: the need for ongoing data to inform public health decision-making.

Surveillance of people's health takes on an important meaning in the practice of public health because it allows monitoring of diseases and prompt response to change in proportions and rates at which diseases occur in populations. Improving health of populations requires establishment of an effective public health system. Population level data and analysis is critically important in government policy and program development and monitoring.

Teledentistry and its applications in paediatric dentistry: A literature review.

Background: During the unfortunate event of the COVID-19 pandemic, restrictions were placed on face-to-face interactions in dentistry to promote social distancing and reduce spread of virus. In order to provide dental services teledentistry was employed.

Objective: This article aims to review the literature and information available on the provision and utilization of teledentistry as a method to address oral health needs of paediatric patients.

Fluorescence and Photoacoustic Spectroscopy-Based Assessment of Mitochondrial Dysfunction in Oral Cancer Together with Machine Learning: A Pilot Study.

The current study reports an integrated approach of machine learning and tryptophan fluorescence and photoacoustic spectral properties to assess the mitochondrial status under oral pathological conditions. The mitochondria in the study were isolated from oral cancer tissues and adjacent normal counterparts, and the corresponding fluorescence and photoacoustic spectra of tryptophan were recorded at 281 nm pulsed laser excitations. A set of features were selected from the pre-processed spectra and were used to classify the data using support vector machine (SVM) learning in the MATLAB platform.

Common Risk Factor Approach to Limit Noncommunicable Diseases and Periodontal Disease-The Molecular and Cellular Basis: A Narrative Review.

Introduction: The link between periodontal disease and noncommunicable diseases (NCDs) has been the subject of major research over the past several years. The primary objective of this review is to understand the cellular and molecular components that link common risk factors (exposure) in adult patients (population) with periodontal disease and other NCDs (outcome). The secondary objective is to interpret from existing literature the possibility of identifying the molecular plausibility of the Common Risk Factor Approach (CRFA).

Oral mucositis: Current knowledge and future directions.

Oral mucositis secondary to head and neck chemoradiation displays a complex molecular pathogenesis involving epithelial and microvascular injury, release of pro-inflammatory cytokines, and host-microbiome communications. These processes lead to oxidative stress and the release of reactive oxygen species that stifle the structural integrity of the oral mucosa, with emergence of erosions and ulcers. The consequences are malnutrition, psychological/psychiatric symptoms, poor quality of life, and occurrence of opportunistic infections.

Assessment of knowledge, attitude and practices among dental practitioners on methods of infection control while carrying out dental procedures during novel coronavirus (COVID-19) pandemic.

Introduction: dental procedures produce bio-aerosols that can carry the highly contagious COVID-19 virus. Hence, the entire dental care team has to follow the current COVID-19 related infection control protocols. The study aims to assess the knowledge, attitude, and practices associated with infection control methods during dental procedures among dental practitioners during the COVID-19 pandemic in India.

MMP-9 Levels and NaOCl Lavage in Randomized Trial on Direct Pulp Capping.

Outcome expectations of direct pulp capping in carious teeth are obscured by a clinically unknown infiltration and breakdown of the dental pulp tissue. Histologic studies showed that this soft tissue breakdown is related to the innate immune system. We hypothesized 1) that a neutrophil biomarker could predict the outcome of direct pulp capping and 2) that using sodium hypochlorite (NaOCl) as a lavage solution to remove necrotized infected pulp tissue could improve it.

Estimation of Age by Evaluating the Occlusal Tooth Wear in Molars: A Study on Dakshina Kannada Population.

Purpose: Assessment of teeth to estimate age in the living as well as the dead is well documented in the literature. Though applied in conjunction with other parameters in Gustafson's technique, attrition of teeth solely is an underexplored indicator for age estimation mainly in India. Most of the studies using attrition of teeth have been conducted in bioarchaeology, and in populations where studies are being conducted in forensic contexts, the results are debatable.

Orofacial granulomatosis: A case report and a proposal of a diagnostic algorithm for oral granulomatous lesions.

Orofacial granulomatosis (OFG) is an uncommon chronic inflammatory disorder with multifactorial etiology and pathogenesis affecting the orofacial region which appears usually as a persistent and/or recurrent swelling that may involve one or both the lips and/or recurrent ulcers along with other orofacial features. The diagnosis of OFG is challenging and it should be ruled out from other conditions characterized by granulomatous inflammation. This article describes a case of a 30-year-old female patient with upper lip swelling as the main manifestation without any systemic involvement and we have also laid down a proposal of a diagnostic algorithm for differential diagnoses and treatment modalities for OFG which could be helpful for the clinician and dentists alike to rule out other granulomatous disorders thus in effective management of OFG.

Effect of Sodium Hypochlorite Concentration in Continuous Chelation on Dislodgement Resistance of an Epoxy Resin and Hydraulic Calcium Silicate Sealer.

The conditioning of the root canal wall during chemo-mechanical root canal treatment differentially affects the adhesion of root canal sealers. This investigation evaluated the impact of sodium hypochlorite (NaOCl) concentration as used in a root canal irrigation concept called continuous chelation, with 1-hydroxyethylidene-1,1-diphosphonic acid (HEDP) contained in the NaOCl solution that is applied. Fourier-transform infrared spectra of the dentinal wall were gathered.

Comparative evaluation of serum cotinine levels in chronic periodontitis and chronic obstructive pulmonary disease.

Context: Periodontitis and chronic obstructive pulmonary disease (COPD) are chronic progressive inflammatory conditions. Smoking has been associated with both chronic periodontitis and COPD. Hence, the present study was designed to correlate serum levels of cotinine with the severity of periodontal disease with or without COPD.
