Background: AI in healthcare services is advancing every day, with a focus on uprising cognitive capabilities. Higher cognitive functions in AI entail performing intricate processes like decision-making, problem-solving, perception, and reasoning. This advanced cognition surpasses basic data handling, encompassing skills to grasp ideas, understand and apply information contextually, and derive novel insights from previous experiences and acquired knowledge. ChatGPT, a natural language processing model, exemplifies this evolution by engaging in conversations with humans, furnishing responses to inquiries. Objective: We aimed to understand the capability of ChatGPT in solving doubts pertaining to symptoms and histological features related to subject of oral pathology. The study’s objective is to evaluate ChatGPT’s effectiveness in answering questions pertaining to diagnoses. Methods: This cross-sectional study was done using an AI-based ChatGPT application that provides free service for research and learning purposes. The current version of ChatGPT3.5 was used to obtain responses for a total of 25 queries. These randomly asked questions were based on basic queries from patient aspect and early oral histopathologists. These responses were obtained and stored for further processing. The responses were evaluated by five experienced pathologists on a four point liekart scale. The score were further subjected for deducing kappa values for reliability. Result & Statistical Analysis: A total of 25 queries were solved by the program in the shortest possible time for an answer. The sensitivity and specificity of the methods and the responses were represented using frequency and percentages. Both the responses were analysed and were statistically significant based on the measurement of kappa values. Conclusion: The proficiency of ChatGPT in handling intricate reasoning queries within pathology demonstrated a noteworthy level of relational accuracy. Consequently, its text output created coherent links between elements, producing meaningful responses. This suggests that scholars or students can rely on this program to address reasoning-based inquiries. Nevertheless, considering the continual advancements in the program’s development, further research is essential to determine its accuracy levels in future versions.

The pigmentation of the fungiform papillae of the tongue is a rare idiopathic condition in which only the fungiform papillae appear hyperpigmented. In the absence of any reviews on the subject, we conducted a systematic review of the aetiopathogenesis and pathophysiology of pigmented fungiform papillae (PFP) of the tongue, including its demographic and histopathological features, trying to outline a possible aetiology. The preferred reporting items for systematic reviews and meta-analyses (PRISMA) was performed using PubMed, Scopus, EMBASE databases and manual searches, for publications between January 1974 and July 2022. Inclusion criteria were case reports defining patients’ characteristics, their general medical and dental conditions, histopathological and/or immunohistochemical findings, all with a final definitive diagnosis of PFP. Overall, 51 studies comprising 69 cases of PFP which included histopathological descriptions were reviewed. Prominent features consisted of hyperpigmentation of melanocytes, melanophages, chromatophores, and a lymphocytic infiltrate in the subepidermal area of the fungiform papillae. On special staining, PFP contained melanin, not iron or hemosiderin. On immunohistochemistry, immune-reactive CD3+ T lymphocytes, S-100 and Sox10, but non-immune-reactive melan-A intraepithelial melanocytes were noted in some studies. The presence of hyperpigmented melanocytes and melanophages, with non-immune-reactive melan-A, suggests that PFP are a benign and physiological form of pigmentation. The inflammatory infiltrates described in some papillary lesions could possibly be due to traumatic events during mastication. Nevertheless, the true reasons for the hyperpigmentation of the fungiform papillae are as of yet elusive, and remain to be determined.

Background: histopathology plays a pivotal role in clinical diagnosis, research, and medical education. In recent years, whole slide imaging (wsi) has emerged as a potential alternative to traditional microscopy for pathological examination. This study aims to provide a comprehensive comparison of wsi and traditional microscopy(tm) in various aspects of histopathology practice. Materials and Methods: In this study, total of 30 cases comprising of oral premalignant and malignant cases which were diagnostically challenging was considered from the archives of the institute for validation. The slides were scanned with slide scanner and were evaluated by histopathologists. The comparative parameters which were noted were diagnostic discordances, number of fields observed to reach the diagnosis and time taken. Results: The mean time taken by the pathologists to reach the diagnosis was significantly less in whole slide imaging technique. The average number of fields observed was higher by using wsi that too in a lesser time compared to tm, the results were found to be statistically significant with p=0.001.however the diagnostic disparity were seen to be maximum for verrucous lesions both in wsi and tm. Conclusion: wsi has facilitated the specialty with rapid mode of diagnosis in a more efficient and error less manner. It has also aided in case banking as well as research possibilities. Hence with the advent of telepathology it is very much necessary to get trained with wsi as early as possible so that the professionals can render correct diagnosis.

Background: Oral cancer is a life-threatening disease that has 377.713 new cases every year and 60% of the 5-year overall survival rate globally. Approximately 84–97% of oral cancer arises from squamous cells, categorized as oral squamous cell carcinoma (OSCC). MiR-21 is a single-stranded, non-coding RNA that has been studied for its role in carcinogenesis. Overexpression of miR-21 is found in various cancers and is linked to a poor prognosis. However, few studies analyze the expression of miR-21 as a diagnostic and prognostic biomarker in oral cancer. Purpose: This review aimed to describe the expression of miR-21 as a novel diagnostic and prognostic biomarker in oral cancer. Review: MiR-21 was found to be upregulated in various cancers, including oral cancer. miR-21 targets several tumor suppressors such as PTEM, TPM1, and PDCD4 to modulate characteristics linked to cancer prognosis, including cell proliferation, apoptosis, invasion, and metastasis. Furthermore, the constant increase of miR-21 expression in healthy oral mucosa to oral potentially malignant disease to OSCC demonstrated its diagnostic value. Conclusion: miRNA-21 may act as a novel diagnostic and prognostic biomarker of oral cancer.

Tooth extraction without socket preservation will lead to reduction in the dimensions and volume of the alveolar bone. Bone defects resulting from tooth extraction not only hinder prosthetic reconstruction but also present aesthetic issues and complicating dental implant treatment. Purple leaves contains flavonoids, steroids, tannins, saponins,and non-toxic alkaloids. These compounds play roles as antimicrobials, immunomodulators, antioxidants, anti-inflammatories, analgesics. Hydroxyapatite has good biocompatibility, and can induce osteoblast differentiation. To investigate the effects of the combining nanoemulsion extract of purple leaves and hydroxyapatite on the expression of RUNX2, OSX, OPN, ALP, and calcium deposition. This research used MTT Assay, ICC, and Alizarin Red staining. The study groups were as follows: Group 1: Ad-MSCs; Group 2: Ad-MSCs + αmem; Group 3: Ad-MSCs + osteogenic medium + 1 % nano-extract of Purple leaves & Hydroxyapatite; Group 4: Ad-MSCs + osteogenic medium + 2 % nano-extract of Purple leaves & Hydroxyapatite. Observations were conducted on days 7, 14, and 21. The combination of nanosuspension extract of Purple leaves and hydroxyapatite significantly increased the expression of RUNX2, OSX, OPN,ALP and calcium deposition compared to other groups. The combination of nanoemulsion extract of Purple leaves and hydroxyapatite were significant (P < 0.05) compared to the control group on each day 7, day 14 and day 21. The combination of nanosuspension extract of Purple leaves and hydroxyapatite was able to enhance the expression of RUNX2, OSX, OPN, ALP, and calcium deposition on days 7,14,21.
