Screening of Oral Squamous Cell Carcinoma Through Color Intensity-Based Textural Features.

Background Early screening and diagnosis of oral squamous cell carcinoma (OSCC) has always been a major challenge for pathologists. Artificial intelligence (AI)-assisted screening tools can serve as an adjunct for the objective interpretation of Papanicolaou (PAP)-stained oral smears. Aim This study aimed to develop a handy and sensitive computer-assisted AI tool based on color-intensity textural features to be applied to cytologic images for screening and diagnosis of OSCC.

Significance of HIF-1α and CD105 in establishing oral squamous cell carcinoma associated with oral submucous fibrosis a distinct clinicopathological entity.

Context: Oral squamous cell carcinoma associated with oral submucous fibrosis (OSCC with OSMF) is clinicopathologically a distinct entity. However, scientific proof in view of assessment of biomarkers of hypoxia and neoangiogenesis to differentiate them are lacking. The expression of hypoxia-inducible factor 1-α (HIF-1α) and CD105 in OSCC with and without OSMF possibly will be explicated along these lines.

Odontogenic tumors: A review of 93 cases in the Vidharba region of Maharashtra.

Background: Tumors of the odontogenic origin (OTs) are rare tumors accounting for 1% of all the jaw tumors in the oral cavity. The behavior of these tumors ranges from hamartomatous proliferation to malignant neoplasm.

Aim: The aim of this study was to determine the epidemiological data, clinical and histopathological picture with variants of the OTs diagnosed at our institute in the Vidarbha region.

Oral submucous fibrosis: An enigmatic morpho-insight.

Oral submucous fibrosis (OSMF) is a chronic progressive, scarring disease affecting oral, oropharyngeal, and sometimes the esophageal mucosa. It is characterized by the progressive fibrosis of the submucosal tissue. The pathogenesis of OSMF has been directly related to the habit of chewing areca nut and its commercial preparation, which is widespread in Indian subcontinent and Southeast Asia.

Ki67, CD105, and α-SMA expression supports the transformation relevant dysplastic features in the atrophic epithelium of oral submucous fibrosis.

Background: The grading of oral epithelial dysplasia is not possible in the atrophic epithelium of oral submucous fibrosis (OSMF). Recently, we found that features such as increased basal cell layer hyperplasia, abnormal superficial mitosis, increased nuclear-cytoplasmic ratio, increased nuclear size, and hyperchromasia represent transformation-relevant dysplastic features in the atrophic epithelium of OSMF. The presence of these features can be considered a high-risk feature for patients.

Early Stage Oral Submucous Fibrosis is Characterized by Increased Vascularity as Opposed to Advanced Stages.

Introduction: The degree of vascularity of the diseased mucosa in Oral Submucous Fibrosis (OSMF) has always been a matter of debate with conflicting results. Knowledge of this aspect is important to understand pathogenesis of OSMF, which in future could be translated into therapeutic strategies.

Aim: In the present study, attempt has been made to investigate parameters like Mean Vascular Density (MVD), Total Vascular Area (TVA) and Mean Vascular Area (MVA) using CD34 antibody.

Impact of virtual microscopy with conventional microscopy on student learning in dental histology.

Background: In dental histology, the assimilation of histological features of different dental hard and soft tissues is done by conventional microscopy. This traditional method of learning prevents the students from screening the entire slide and change of magnification. To address these drawbacks, modification in conventional microscopy has evolved and become motivation for changing the learning tool.

Oral squamous cell carcinoma in the background of oral submucous fibrosis is a distinct clinicopathological entity with better prognosis.

Background: The aim of this study was to compare the clinicopathological features of oral squamous cell carcinoma in the background of oral submucous fibrosis (OSCC-OSMF) and oral squamous cell carcinoma (OSCC).

Methods: A total of 217 cases of OSCC were retrieved from achieves for the analysis. OSCC-OSMF cases were segregated on the basis of history and clinicopathological parameters.

Matrix metalloproteinases-3 gene-promoter polymorphism as a risk factor in oral submucous fibrosis in an Indian population: a pilot study.

Aim: Host-related factors could be important to the fundamental understanding of oral diseases. One such factor is matrix metalloproteinases (MMP). MMP3 (stromelysin 1) is crucial in connective tissue remodeling.

Evaluation of Effect of Astringent on Oral Mucosa as a Non-surgical Preprosthetic Treatment Modality in Edentulous Patients: An In Vivo Study.

Preprosthetic treatments are advocated in edentulous patients to enhance the denture bearing areas for good denture support. Most of the times the preprosthetic treatments are considered only in a surgical way. Ideally every edentulous patient undergoing complete denture treatment needs a non-surgical preprosthetic treatment.

Evaluation of chemiluminescence, toluidine blue and histopathology for detection of high risk oral precancerous lesions: A cross-sectional study.

Background: Early detection holds the key to an effective control of cancers in general and of oral cancers in particular. However, screening procedures for oral cancer are not straightforward due to procedural requirements as well as feasibility issues, especially in resource-limited countries.

Methods: We conducted a cross-sectional study to compare the performance of chemiluminescence, toluidine blue and histopathology for detection of high-risk precancerous oral lesions.
