COVID-19 in Smokeless Tobacco Habitués: Increased Susceptibility and Transmission.

As the coronavirus disease (COVID-19) pandemic continues to sweep across the globe, the world is responding by implementing public awareness campaigns, social distancing measures, and other preventive strategies to arrest the spread of this lethal disease. Infection with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) exacts a heavy toll on patients with existing comorbidities. Smokeless tobacco (SLT) consumption is of particular concern in countries in South Asia with high population densities, as it facilitates exposure to SARS-CoV-2 within or between communities by the act of public spitting.

Obesity and its association with chronic periodontitis: A cross-sectional study.

Background: Relationship among periodontitis, obesity, and chronic diseases may be multidirectional. Inflammatory diseases such as periodontitis induce the production of pro-inflammatory cytokines such as TNF-α, IL-1, and IL-6. It has been suggested that the secretion of TNF-α by adipose tissue triggered by lipopolysaccharides from periodontal Gram-negative bacteria promotes hepatic dyslipidemia and decreases insulin sensitivity.

Estimation of Salivary sCD14 in Children with Early Childhood Caries in Association with Pneumonia.

Background: Dental caries is a chronic disease among children and pneumonia is often seen in young children. Soluble CD14 (sCD14) protein is released by monocytes and changes in periodontal infection. The study aimed to estimate the level of salivary sCD14 in children with early childhood caries in association with pneumonia.

Evaluation of Salivary Parameters and Oral Health Status Among Asthmatic and Nonasthmatic Adult Patients Visiting a Tertiary Care Hospital.

Introduction: Asthma is a chronic inflammatory disorder of the airways characterized by attacks of bronchoconstriction causing shortness of breath, coughing, and rapid breathing. Patients undergoing inhalation therapy are subjected to a higher risk of dental caries due to the reduced saliva secretion, decreased pH value, increased number of cariogenic bacteria caused by inappropriate oral hygiene, and the use of inhaling medicaments with dry powder.

Methods: The descriptive study was carried out among 200 patients aged (18-45 years) visiting Yenepoya Hospital, Mangalore during the period from May 2018 to October 2018 to evaluate salivary parameters and oral health status in asthmatic and nonasthmatic patients.

Maxillary and mandibular unusually large radicular cyst: A rare case report.

Radicular cysts are the most common odontogenic cyst. It is an inflammatory cyst associated with the root apex of a nonvital tooth. Most radicular cysts are small but can reach a large size causing displacement of surrounding structures.

Comparative Evaluation of Remineralization Potential of Two Varnishes Containing CPP-ACP and Tricalcium Phosphate: An Study.

Aim: The aim of this study is to evaluate the remineralization potential of Clinpro XT varnish containing tricalcium phosphate (TCP) and MI varnish containing casein phosphopeptide (casein phosphopeptide-amorphous calcium phosphate, CPP-ACP).

Materials And Methods: Thirty premolar teeth were taken and divided into three groups. Samples were sliced mesiodistally into buccal and lingual halves using a diamond disk bur.

Establishing a new staging system for oral submucous fibrosis and correlation of the proposed staging system to traditional histopathological grading: A clinico-histopathological study.

Background & Objectives: Oral submucous fibrosis (OSF) is a potentially malignant disorder of the oral cavity leading to reduction in mouth opening. Mouth opening assessment is used as one of the methods to assess the severity of the disease. In this study the normal maximum mouth-opening capacity of an individual is considered in assessing the reduction in mouth opening.

Objective: To study the effect of radiation therapy on the structural and elemental composition of permanent teeth enamel in vitro.

Methods: Sections from 21 noncarious healthy human teeth were exposed to a cumulative radiation dose of 20-80 Gy. The sections were subjected to electron dispersive spectroscopy (EDS), Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) analysis to study the elemental composition, the ratio of inorganic and organic content, and the mineralization and crystalline properties of the hydroxyapatite crystal structure respectively.

Omics data-driven analysis identifies laminin-integrin-mediated signaling pathway as a determinant for cell differentiation in oral squamous cell carcinoma.

Background: In recent years, high-throughput omics technologies have been widely used globally to identify potential biomarkers and therapeutic targets in various cancers. However, apart from large consortiums such as The Cancer Genome Atlas, limited attempts have been made to mine existing datasets pertaining to cancers.

Methods And Results: In the current study, we used an omics data analysis approach wherein publicly available protein expression data were integrated to identify functionally important proteins that revealed consistent dysregulated expression in head and neck squamous cell carcinomas.

Stem Cells and Their Application in Dentistry: A Review.

The use of the term "stem cells" dates back to the 1800s; however, the application of the same is still not completely understood. Recent advances have indicated the harvesting of postnatal stem cells from sources such as the dental pulp and fat. The pluripotent nature of these cells allows for use in various aspects of treatment and patient care such as organ and tissue transplantation, bony defects repair, distraction osteogenesis, cell therapies, gene therapy, and toxicology testing of new drugs.
