The aim of this systematic review was to investigate the malignant transformation of oral leukoplakia (OL) infected with Candida. Literature search was conducted using Medical Subject Heading terms ‘leukoplakia’, ‘neoplasms’, ‘ Candida’, ‘malignant transformation’ and ‘oral’ and included all results until February 2017. The initial search identified 372 articles, which was consolidated to 16 articles after applying inclusion and exclusion criteria. The occurrence of candidal infection in OL ranged from 6.8% to 100.0%. Only 3 of 16 studies reported malignant transformation rates of leukoplakia with Candida infection. The overall malignant transformation rates reported in these studies were 2.5%, 6.5% and 28.7%. This review supports the contention that candidal infection promotes cellular and dysplastic changes in OL. However, further follow-up studies are recommended to confirm the role of Candida infection in malignant transformation of OL lesions.

Objective: To examine the immunohistochemical expression of four members of the type 1 growth factor receptor family in oral squamous cell carcinomas (OSCCs) and to correlate with clinical outcomes. Materials and methods: Sixty OSCCs from a patient cohort in Sri Lanka were included in the study. Five sections from each carcinoma were immunostained with antibodies to epidermal growth factor receptor (EGFR)/c-erbB-1, c-erbB-2/HER-2/neu, c-erbB-3/HER-3 and c-erbB-4/HER-4. Two clones were used to stain for c-erbB-2/HER-2/neu. Semiquantitative analysis of immunoreactivity was carried out by scoring the intensity of expression and proportions of positively stained cells. A logistic regression analysis was performed to examine positive expression against overall survival. Results: There was heterogenous expression of the four receptors, positivity ranging from 26% to 60%. Co-expression of all four markers was observed only in 1–3% of the tumours. Both membranous and cytoplasmic expressions were observed, EGFR showing predominantly membranous expression and c-erbB-2 showing only cytoplasmic staining. In logistic regression analysis, none of the growth factor receptors were significantly predictive of overall survival. Conclusion: Type 1 growth factor receptors are highly expressed in oral carcinomas, EGFR being the predominant marker.
Background: The first consultation with a health-care professional is crucial to make the correct diagnosis particularly with respect to narrating the symptoms encountered by the patient. Yet, currently, no information is available concerning the primary symptoms documented by patients with oral submucous fibrosis (OSF). Materials and Methods: A total of 158 OSF patients visiting outdoor patient departments (OSF-OPDs) and 104 pan shop customers (PSCs) were investigated. OSF-OPD cases and relevant PSCs cases were investigated to discover the chief complaints (CCs) leading to dental visits. Detailed demographic data, patient histories concerning relevant habits (with duration), and socioeconomic status were recorded. OSF cases were graded based on the degree of mouth opening. Results: Out of 158 OSF-OPD patients, only 43 (26.58%) reported relevant disease symptoms of OSF: in stage III, 28.57%, or stage IV, 38.09%. One hundred and sixteen patients (73.41%) reported CCs unrelated to OSF, and all of these cases were diagnosed with an early stage of OSF (stage I: 47.05% and stage II: 22.5%). Out of the total 104 PSCs, 66 PSCs have had prior dental consultations, but only five (4.80%) individuals had visited a health-care professional due to OSF-related CCs. Conclusion: A significant number of CCs made by OSF patients were unrelated to their disease signs and symptoms. There is a lack of awareness of OSF symptoms by pan chewers, thus hindering early detection.
Objectives: The purpose of this study was to review and evaluate the characteristics of 100 most cited articles on ameloblastoma (AB). Materials and Methods: A comprehensive list of citation classics in AB was generated by searching the Scopus database without year or language restrictions. The top 100 articles were retrieved after reading abstracts or full texts. The following study variables were evaluated: number of citations, citation density, journal name, impact factor, category and quartile of journals, publication year, authors with their affiliations, and article type. Results: The citation number ranged from 76 to 367, with a mean of 122.78 citations per article. The one hundred top cited articles were distributed in 41 journals with Cancer having the highest number of articles (n = 16). There was a dominance of authors form United States (42 articles). The articles were published from 1955 to 2014, and eight authors published more than three papers. There were 57 research articles and 43 review articles. Conclusions: This first citation analysis provide a detailed list of the most influential articles on AB to help recognize the quality of the works, discoveries, and the trends steering the study of AB.
