OBJECTIVE: To examine all studies reporting prevalences of oral lichen planus (OLP) for epidemiological validity and to extract prevalence data from the valid papers. DESIGN: Computer based literature searches were carried out using the MeSH headings 'lichen planus, oral and (prevalence or incidence)' and were supplemented by manual searching. MAIN OUTCOME MEASURES: Each paper was examined for five criteria: clinic-based or population study, adequate demographic description (by sex and age group) of the population, adequate demographic description of the sample (if the population was sampled), adequate demographic description of the OLP cases identified, and histological confirmation of the clinical diagnosis. RESULTS: Forty-five relevant papers were identified, 21 clinic-based and 24 population studies. All but one of the population studies was deficient. One study, while having some defects, was probably sufficiently valid to permit the findings to be regarded as useful. An overall age-standardized prevalence of 1.27% (0.96% in men and 1.57% in women) can be calculated from this study. CONCLUSIONS: There appears to be only one usable prevalence study of OLP. Other large-scale studies are required in other populations. Such studies need to distinguish between OLP and lichenoid reactions.

Ossifying fibroma: a systematic review

Objective The aim of this study was to detect salivary glucose levels in diabetic and nondiabetic subjects, to study the relationship between salivary glucose levels and salivary candidal carriage, and to determine if salivary glucose levels could be used as a noninvasive tool to monitor glycemic control in diabetics. Study design A total of 150 adults, 100 with type 2 diabetes and 50 without diabetes (control subjects), aged 40-60 years, participated in the study. Diabetic status was determined by estimation of random nonfasting plasma glucose levels and glycosylated hemoglobin levels. Both unstimulated and stimulated saliva were collected and investigated for glucose levels and colony-forming units (CFU) of Candida . Salivary glucose levels were measured using the glucose-oxidase method. Results Salivary glucose levels were significantly higher in diabetics than nondiabetics. There was a significant positive correlation between salivary and plasma glucose levels. Candidal CFUs were significantly higher in diabetic subjects and showed a significant positive correlation with salivary (unstimulated and stimulated) glucose levels. Conclusions These results show that salivary glucose concentration is a potentially useful noninvasive tool to monitor glycemic control in diabetic patients. Increased salivary glucose is associated with increased prevalence of oral Candida in these subjects.

Preoperative, intraoperative, and postoperative complications in orthognathic surgery: a systematic review

Matrix metalloproteinase-9 (MMP-9) is an inducible enzyme. Oral potentially malignant disorders (OPMDs) are considered as the early tissue changes that happen due to various habits such as smoking tobacco, chewing tobacco or stress. This alteration in the tissues alters the expression of MMP-9. The rationale of the review is to know the expression of MMP-9 in OPMDs. Hand searching and electronic databases such as PubMed and ScienceDirect were done for mesh terms such as OPMDs and MMP-9. Eight articles were obtained, after applying inclusion and exclusion criteria. These articles were assessed with QUADAS and data were extracted and evaluated. The included eight studies were done in 182 oral squamous cell carcinoma cases, 430 OPMDs (146 oral lichen planus, 264 leukoplakia and 20 oral submucous fibrosis) and 352 healthy controls evaluated for MMP-9. MMP-9 expression was found to be elevated in tissue, serum and saliva samples of OPMDs than in healthy controls. There is only one study in each serum and saliva samples to evaluate MMP-9. Saliva being noninvasive and serum being minimally invasive, more studies need to be done in both serum and saliva to establish MMP-9 as an early diagnostic marker in OPMDs to know its potential in malignant transformation.

Expression of matrix metalloproteinase-9 in oral potentially malignant disorders: A systematic review

BACKGROUND: Smoking, drinking and chewing tobacco product, common habits in India have been positively associated with oral lesions. No study has been conducted in this part of Tamilnadu regarding the prevalence of oral lesions in relation to habits. METHODS: A hospital based cross-sectional study was carried out at Ragas Dental College, Chennai. Already existing data of two thousand and seventeen consecutive patients from sub-urban areas of Chennai, who attended the outpatient department, at Ragas Dental College, for dental complaints during a period of three months in 2004, who underwent oral examination and interviewer based questionnaire was used. RESULTS: Oral soft tissue lesions were found in 4.1% of the study subjects. The prevalence of leukoplakia, OSF and oral lichen planus was 0.59%, 0.55%, and 0.15% respectively. The prevalence of smoking, drinking alcoholic beverages and chewing was 15.02%, 8.78% and 6.99% respectively. Smoking and chewing were significant predictors of leukoplakia in this population. DISCUSSION: The prevalence of leukoplakia, OSF and oral lichen planus in our study population is similar to those found in other populations. The prevalence of consumption of alcoholic beverages in our study population was higher when compared to the Indian National Sample Survey study. However the prevalence of smoking and chewing was found to be lower. Smokers were more likely to develop smoker's melanosis compared to other lesions. Among those who consumed alcoholic beverages alone, the prevalence of leukoplakia was higher compared to other lesions. OSF was the most prevalent lesion among those who chewed panmasala or gutkha or betel quid with or without tobacco.

Cemento-ossifying fibromas form a part of the spectrum of fibro-osseous lesions of the jaws and are considered benign but locally aggressive tumors. This report presents a 31-year-old female patient with a large cemento-ossifying fibroma of the maxilla, expanding into the orbit and causing proptosis. The report also discusses the surgical management of this lesion with successful preservation of optic nerve function and normal vision.
