It is the third most frequent reason for individuals to seek dental treatment, after dental caries and periodontal diseases. For an in-depth exploration of the topic of halitosis, an extensive literature review was conducted. The review focused on articles published in peer-reviewed journals and only those written in the English language were considered. The search for relevant literature began by employing subject headings such as 'halitosis, oral malodor, volatile sulfur compounds, artificial intelligence, and olfaction' in databases such as PubMed/Medline, Scopus, Google Scholar, Web of Science, and EMBASE. Additionally, a thorough hand search of references was conducted to ensure the comprehensiveness of the review. After amalgamating the search outcomes, a comprehensive analysis revealed the existence of precisely 134 full-text articles that bore relevance to the study. Abstracts and editorial letters were excluded from this study, and almost 50% of the full-text articles were deemed immaterial to dental practice. Out of the remaining articles, precisely 54 full-text articles were employed in this review. As primary healthcare providers, dentists are responsible for diagnosing and treating oral issues that may contribute to the development of halitosis. To effectively manage this condition, dentists must educate their patients about the underlying causes of halitosis, as well as proper oral hygiene practices such as tongue cleaning, flossing, and selecting appropriate mouthwash and toothpaste. This narrative review summarises all possible AI olfaction in halitosis.","PeriodicalId":38846,"journal":{"name":"Journal of Oral and Maxillofacial Pathology","volume":"28 2","pages":"275-283"},"PeriodicalIF":0.0,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11329069/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142000946","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Teeth are the most stable part of the human body and are resistant to thermal, mechanical, and chemical insults. The aim of this study was to evaluate the effectiveness of mandibular intercanine distance and mesiodistal width of mandibular first molar in gender determination.Materials and methods: The study comprised 100 participants (50 males and 50 females) in the age group of 18-23 years. The mandibular impressions were made, and casts were prepared using dental stone. The intercanine distance and mesiodistal width of the right mandibular first molar were measured using digital vernier callipers. The data obtained was statistically analysed using SPSS software version 23.Results: The mean mandibular intercanine distance was found to be 27.2 ± 2.3 in males and 25.94 ± 1.76 in females (P = 0.03). There was no statistical difference in the mesiodistal width of the mandibular molar between males and females (P = 0.166). However, the mean mesiodistal width of males was higher when compared to females.Conclusion: Males have a greater intercanine width and mesiodistal dimension when compared to females.

There are no clear cut indicators available currently to identify the lymph node metastases and overall prognosis in HNSCC. Thus, the current study was conducted to correlate the immunoexpression of cytokeratins (CK) 8, 10, and 14 with lymph node metastases and tumour differentiation in patients with HNSCC.Material and methods: The study population included 61 retrospective cases of HNSCC with lymph node metastases (n = 31) and without lymph node metastases (n = 30). Expression of CK 8, 10, and 14 was assessed by immunohistochemical staining procedure. Using Pearson's Chi-square test and Spearman's correlation coefficient, the correlation of these markers with lymph node metastases and tumour differentiation was statistically analysed.Results: The expression of CKs in HNSCC cases was higher than in controls. In nodal metastasis cases, CK 8 expression was noted in >50% of the tumour cells at the invasive tumour front (ITF) (P value 0.008), and in cases without nodal metastasis, <1% or negative expression was noted. CK 10 expression gradually decreased as the tumour grade increased. Association of CK 10 expression and tumour differentiation exhibited statistically significant results (P value 0.03). CK 14 expression was noted in the entire epithelium and at the ITF, strongly in most cases; however, CK 14 did not correlate with the lymph node metastasis and tumour differentiation as well.Conclusion: We found a strong correlation of CK 8 expression with nodal metastasis in HNSCC, and it can be utilised as a reliable prognostic indicator.","PeriodicalId":38846,"journal":{"name":"Journal of Oral and Maxillofacial Pathology","volume":"28 2","pages":"247-252"},"PeriodicalIF":0.0,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11329098/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142000911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The formation of these calcifications begins with concentric layers of calcified tissue within which remnants of necrotic and calcified cells may be present. The calcifications of thrombi in blood vessels, called phleboliths, may also serve as nidi for denticles. In metabolic diseases such as diabetes, hypertension or poor periodontal health, there are obvious changes in blood vessels and vascularization. In our study, we observed histopathological sections of dental pulp and correlated systemic diseases such as diabetes and hypertension with poor periodontal health and dental pulp stones.Aim: The aim of our study was to evaluate the histopathology of dental pulp stones, their distribution among various age groups and sexes and to identify any correlations between pulp stone formation and systemic diseases such as type II diabetes and hypertension.Materials and methods: Samples from 100 patients with metabolic diseases such as type II diabetes and hypertension were collected. The pulp was extirpated from the teeth that were undergoing root canal treatment, and the teeth were extracted. The collected pulp sample was fixed in 10% formaline neutral buffer, subjected to routine histopathological procedures and stained with haematoxylin and eosin. The pulp of teeth extracted for orthodontic treatment was considered a control for patients with no metabolic disease.Results: There was a definite relationship between increased pulp stones and metabolic diseases such as type II diabetes and hypertension; likewise, poor periodontal health was significantly related to pulp stones.","PeriodicalId":38846,"journal":{"name":"Journal of Oral and Maxillofacial Pathology","volume":"28 2","pages":"192-199"},"PeriodicalIF":0.0,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11329071/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142000914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
