Quality Assessment of Information on Oral Cancer Provided at Arabic Speaking Websites.

BACKGROUND: Patients often use Inernet to explore information about their health and disease. This study aimed to evaluate the quality of information on oral cancer provided at Arabic websites. MATERIAL AND METHOD: The translated Arabic keywords of "oral cancer" and treatment of oral cancer" and 6 search engines were used. The top 100 websites were selected. Irrelevant and duplicates websites were excluded. To evaluate the quality of websites and their information, DISCERN, HON, and JAMA benchmarks were used. RESULTS: The majority (n = 64, 74.4%) of websites were founded by profit organizations. The mean overall rating was 2.23 (1.6) out of 5 and the median overall rating was 1 (1-3) based on DISCERN. According to HON, only 4.7% of the websites achieved a high score (≥75) and 37.2% of the websites gained a low score (<50). Based on JAMA benchmarks, 15% of the websites did not fulfill any criteria and only 2% of them fulfilled the four criteria proposed by the JAMA benchmarks. CONCLUSION: This study suggested the poor quality of web-based Arabic information on oral cancer. It is recommended to develop a websites based system by which enable to the Arabic websites related to oral cancer know their shortfalls, therefore, improve their quality according to evaluation tools which will ensure finding reliable data from the websites.

What Is the Most Effective Rehabilitation Method for Posterior Maxillas With 4 to 8 mm of Residual Alveolar Bone Height Below the Maxillary Sinus With Implant-Supported Prostheses? A Frequentist Network Meta-Analysis.

PURPOSE: The most effective rehabilitation method for patients with edentulous posterior maxillas with an intermediate (4 to 8 mm) residual bone height (RBH) below the maxillary sinus is unclear. Evidence derived from conventional meta-analysis is limited because of the lack of head-to-head studies. This network meta-analysis (NMA) was performed to identify the most effective method to treat patients with intermediate posterior RBH. MATERIALS AND METHODS: An NMA of randomized controlled clinical trials (RCTs) was conducted to assess various rehabilitation methods using implant-supported prostheses for patients with intermediate posterior maxillary RBH (4 to 8 mm). Publications from 1970 through March 2018 in 3 major databases were searched. Parallel and split-mouth RCTs that reported the outcomes of interest with follow-up of at least 6 months from initial loading were included. Predictor variables were short implants (SIs; ≤8 mm) alone, SIs in conjunction with osteotome sinus floor elevation (OSFE) with or without bone grafting, long implants (LIs) in conjunction with OSFE with and without bone grafting, and LIs combined with lateral sinus floor elevation (LSFE) with bone grafting. Outcome variables were implant and prosthesis failure rates, marginal bone loss, and complications. Frequentist NMA was performed using STATA software. RESULTS: Twenty RCTs involving 770 patients with intermediate posterior maxillary RBH and 837 concerned maxillary sinuses who received 1,486 implants using any of the 4 rehabilitation methods were included. There were no statistically significant differences among the 4 groups for implant and prosthesis failure rates and marginal bone loss at follow-up (range, 6 months to 5 years after loading). There was a marked decrease in complications for SIs alone compared with LIs combined with LSFE. For implant and prosthesis survival rates, SIs in conjunction with OSFE with or without bone grafting ranked first as the most effective option (77.1%) followed by LIs plus OSFE with or without bone grafting (62%), LIs plus LSFE with bone grafting (43.9%), and SIs alone (24.8%). CONCLUSION: There is moderate-quality evidence derived from this NMA showing that OSFE combined with SI or LI placement with or without bone grafting or SI placement alone is superior to LI placement combined with LSFE and bone grafting when used for patients with intermediate maxillary RBH (4 to 8 mm). Furthermore, the results of this study show that LSFE for patients with intermediate RBH is not a suitable treatment option because of unjustified high cost and rate of complications.

Efficacy of low-level laser therapy in management of symptomatic oral lichen planus: a systematic review.

Oral lichen planus (OLP) is a chronic inflammatory disease of unknown etiology and indefinite cure. This systematic review assessed the efficacy of low-level laser therapy in the treatment of symptomatic OLP. Electronic databases (PubMed, Scopus, and Web of Science) were searched from date of inception till and including December 2016, using various combinations of the following keywords: oral lichen planus, laser therapy, low-level laser therapy, and phototherapy. Owing to heterogeneity of data, no statistical analyses were conducted. Initially, 227 publications were identified. After selection, only six studies were included in this systematic review. In these studies, the laser wavelengths, power output, and duration of irradiation ranged between 630-980 nm, 20-300 mW, and 10 s-15 min, respectively. All of the included studies found laser to be effective in management of OLP, without any reported adverse effects. The results of the included studies confirm that low-level laser therapy is effective in management of symptomatic OLP and can be used as an alternative to corticosteroids. However, due to variety of methods and substantial variations in laser parameters among these studies, more randomized clinical trials with large sample sizes are highly warranted.

Prevalence and association of smokeless tobacco use with the development of periodontal pocket among adult males in Dawan Valley, Yemen: a cross-sectional study.

BACKGROUND: The traditional type of smokeless tobacco used in the Arabian Peninsula, particularly common in Yemen, is called shammah. This study aims to determine the prevalence of shammah use and its association with the development of periodontal pockets. Other associated factors with the development of periodontal pocket were also determined. METHODS: This cross-sectional study included 346 adult males aged 18 years old to 68 years old. Socio-demographic characteristics, oral hygiene practices, and shammah use history were surveyed by using a structured interview questionnaire. The clinical assessment for the presence or absence of periodontal pockets was assessed on the basis of community periodontal index. The chi-square test was used to assess significant differences in study groups in terms of the presence of periodontal pockets. Multivariable logistic regression was selected to assess potential associated factors with the development of periodontal pockets. RESULTS: Among the 346 adult males, 248 (71.7 %), 30 (8.6 %), and 68 (19.7 %) males never used shammah, were former shammah users, and were current shammah users, respectively. The significant associated factors with the development of periodontal pocket were age group (30 years old and above) (Adjusted Odds Ratio (AOR) = 2.03, 95 % CI: 1.13, 3.65; P = 0.018), low family income category (AOR = 2.35, 95 % CI: 1.39, 3.99; P = 0.001), former shammah user (AOR = 2.66, 95 %: CI: 1.15, 6.15; P = 0.022), and current shammah user (AOR = 6.62, 95 %: CI: 3.59, 12.21; P = 0.001). CONCLUSIONS: The results revealed that periodontal pockets were significantly associated with age group (30 years old and above), low family income category, former shammah use, and current shammah use. The findings of the current study highlighted the need to develop comprehensive shammah prevention programs and reduce periodontal disease and other shammah-associated diseases.

Association between Shammah Use and Oral Leukoplakia-like Lesions among Adult Males in Dawan Valley, Yemen.

BACKGROUND: Shammah is a traditional form of snuff dipping tobacco (a smokeless tobacco form) that is commonly used in Yemen. Oral mucosal changes due to the use of shammah can usually be observed in the mucosal surfaces that the product touches. The aim of this study was to determine the association between shammah use and oral leukoplakia-like lesions. Other associated factors were also determined. MATERIALS AND METHODS: A cross sectional study was conducted on 346 randomly selected adult males. Multi-stage random sampling was used to select the study location. After completing the structured questionnaire interviews, all the participants underwent clinical exanimation for screening of oral leukoplakia-like lesions Clinical features of oral leukoplakia-like lesion were characterized based on the grades of Axell et al (1976). Univariable logistic regression and multivariable logistic regression were used to assess the potential associated factors. RESULTS: Out of 346 male participants aged 18 years and older, 68 (19.7%) reported being current shammah users. The multivariable analysis revealed that age, non-formal or primary level of education, former shammah user, current shammah user, and frequency of shammah use per day were statistically associated with the presence of oral leukoplakia-like lesions [Adjusted odds ratio (AOR) = 1.03; 95% confidence interval (CI) : 1.01, 1.06; P= 0.006], (AOR= 8.65; 95% CI: 2.81, 26.57; P= 0.001), (AOR= 3.65; 95% CI: 1.40, 9.50; P= 0.008), (AOR= 12.99; 95% CI: 6.34, 26.59; P= 0.001), and (AOR= 1.17; 95% CI: 1.02, 1.36; P= 0.026), respectively. CONCLUSIONS: The results revealed oral leukoplakia-like lesions to be significantly associated with shammah use. Therefore, it is important to develop comprehensive shammah prevention programs in Yemen.
