Fulltext Assessing oral cancer knowledge and awareness among Malaysian dental and medical students

Awan KH, Khang TW, Yee TK, Zain RB

J Cancer Res Ther, 2014 Oct-Dec;10(4):903-7.
PMID: 25579526 DOI: 10.4103/0973-1482.138011

BACKGROUND:
Oral cancer is a foremost health dilemma in several regions of the world. General dental practitioners and general medical practitioners play a major role in recognition of oral mucosal changes that may lead to malignancy. Their knowledge in oral cancer itself and the risk factors associated with the disease need to be sufficient.

OBJECTIVE:
The objective of the present study was to investigate awareness and knowledge of undergraduate dental and medical students in early detection and prevention of oral cancer.

MATERIALS AND METHODS:
Dental and medical students were invited to participate by answering a questionnaire on their habits of the oral mucosa examination and history taking, knowledge on risk factors and changes related with oral cancer, referral of patients as well as their desire to receive further information on oral cancer. Chi-square test was carried out to analyze knowledge and awareness between undergraduate dental and medical students.

RESULTS:
Undergraduate dental students were more likely to examine oral mucosa (96.7%) and advice risk habits to patients (93.9%) compared to medical students (60.6% and 79.8% respectively). Significantly more dental students considered smoking (84.4%), betel quid chewing (76.1%), and alcohol drinking (35%) as risk factors. Clinical changes of oral cancer were better identified by dental students (leukoplakia-52.8%, erythroplakia-45%, and non-healing ulcer-40%) compared to medical students (leukoplakia-12.9%, erythroplakia-4.6%, and non-healing ulcer-10.3%). Both dental and medicals students reported the desire to receive further information in relation to oral cancer.

CONCLUSION:
Dental students have better knowledge and awareness in prevention and early detection of oral cancer compared to medical students.

PMID: 25825114

Oral submucous fibrosis is a chronic, progressive scarring disease associated with both significant morbidity including pain and limited mouth opening and an increased risk for malignancy. This systematic review evaluated the different medicinal (i.e. nonsurgical) interventions available for the management of oral submucous fibrosis. An automated literature searches of online databases from January 1960 to December 2013 were performed and only studies with high level of evidence based on the guidelines of the Oxford Centre for evidence-based medicine were selected. Thirteen studies (3 randomized controlled trials and 10 clinical trials/controlled clinical trials) were included and drugs like steroids, hyaluronidase, human placenta extracts, chymotrypsin and collagenase, pentoxifylline, nylidrin hydrochloride, iron and multivitamin supplements including lycopene were used. There is a clear lack of evidence on the available drug treatment for oral submucous fibrosis and further high quality randomized controlled trials are needed to evaluate the different therapeutic agents.

BACKGROUND: Oral lichen planus (OLP) is a relatively common inflammatory disease, with unclear etiology. A number of studies have linked Epstein-Barr virus (EBV) with OLP. The present systematic review and meta-analysis aimed to evaluate the available evidence regarding the potential association between EBV and OLP.
METHODS: Online databases (PubMed, Scopus, Web of Science, ProQuest, and Google Scholar) were searched from date of inception till May 2020. Studies were included if they met the following criteria: 1) observational studies that assessed the relationship between EBV and OLP, 2) the study comprised OLP patients and control subjects, 3) diagnosis of OLP was confirmed histopathologically, and 4) articles were in English. Studies without control groups, experimental studies, case reports, and reviews were excluded. The fixed-effects model was performed for meta-analyses using RevMan 5.3 software.
RESULTS: A total of 10 studies comprising 386 OLP cases and 304 controls were included. Of these, only 8 studies were eligible for the meta-analysis. The results of the quality assessment showed that only 2 studies were of high quality, while the remaining studies were of moderate quality. The results of the pooled eight studies revealed a significant positive association between EBV and OLP (OR = 4.41, 95% CI: [2.74, 7.11], P
Fulltext Assessing the potential association between Epstein-Barr virus and oral squamous cell carcinoma: a systematic review and meta-analysis

Sivakumar S, Gupta AA, Nik Mohd Rosdy NMM, Venkiteswaran A, Raj AT, Awan KH

Transl Cancer Res, 2020 Apr;9(4):3092-3100.
PMID: 35117672 DOI: 10.21037/tcr.2020.01.09

BACKGROUND: This study aims to qualitatively and quantitatively review the association between Epstein-Barr virus (EBV) and oral squamous cell carcinoma (OSCC).
METHODS: PubMed, Scopus, and Web of Science databases were searched using the keywords "EBV or Epstein Barr virus and Oral cancer or Oral squamous cell carcinoma" for published case-control studies in the English language upto August 2019.
RESULTS: The search yielded 985 articles out of which 966 articles were excluded by screening their titles and abstracts as they were irrelevant or duplicates. Based on the full-text assessment of the remaining 19 articles, only 7 satisfied the inclusion criteria and were included in the qualitative analysis, out of which only 4 were compatible to be included in the meta-analysis. The diagnostic modalities used included immunohistochemistry, in situ hybridization and polymerase chain reaction. The diagnostic targets included latent membrane protein (LMP)-1, EBV determined nuclear antigen-1, EBV-encoded small non-polyadenylated RNA-2. The meta-analysis showed that there is an association between the EBV and OSCC.
CONCLUSIONS: Determining the association of EBV with OSCC is highly tedious due to the contrasting data obtained from individuals' studies which in turn is due to the wide variations in the sensitivity and specificity of the diagnostic modalities used and diagnostic targets selected. Although the meta-analysis revealed an association between EBV and OSCC, the number and the quality of the studies included in the meta-analysis are limited, thus the association requires further validation for any conclusive inference.
Prosthetic Rehabilitation of Microstomia Patients: A Systematic Review of Published Case Reports and Case Series

Patil S, Raj AT, Sarode SC, Sarode GS, Menon RK, Bhandi S, et al.

J Contemp Dent Pract, 2019 Apr 01;20(4):508-515.
PMID: 31308286

STATEMENT OF PROBLEM: Prosthetic techniques commonly employed for the rehabilitation of edentulous patients might not be adequate in the treatment of patients with microstomia.
PURPOSE: The purpose of this paper is to systematically review all the prosthetic techniques that have been used in the oral rehabilitation of patients with microstomia.
MATERIALS AND METHODS: Data sources, including PubMed, Google Scholar, SCOPUS and Web of Science, were searched for case reports and case series published through September 2017. Three investigators reviewed and verified the extracted data. Only case reports and case series on prosthetic rehabilitation in microstomia patients published in the English language were considered eligible.
RESULTS: A total of 212 records were identified from the database search. Forty duplicate records were removed. The remaining 172 articles were assessed for eligibility, and 139 articles were removed because they did not satisfy the inclusion criteria. A total of 34 cases (including 32 case reports and 1 case series) were finally included in the qualitative analysis. The review revealed the use of a modified impression technique with flexible and sectional trays to record impressions in patients with microstomia. Modified forms of oral prostheses ranging from sectional, flexible, collapsible and hinged dentures to implant-supported prosthesis were fabricated to overcome the limited mouth opening. The success of the prosthetic technique primarily depended on the extent of the microstomia and the nature of the cause of the microstomia.
CONCLUSION: Even though the patient acceptance of the prosthetic techniques summarized in the systematic review were high, long-term success rates for each option could not be assessed because of the short follow-up time in most of the included case reports and series.
