Oral mucosal lesions in adult Chinese

The objectives of this analysis were to determine the prevalence of oral mucosal lesions (OML) among adults in Southern China and to determine possible associations between OML and reported tobacco-smoking and alcohol-drinking habits. The sample consisted of 1573 35- to 44-year-old and 1515 65- to 74-year-old Chinese from both urban and rural areas of Guangdong Province. The subjects were interviewed by trained interviewers and underwent a clinical examination of the oral mucosa performed according to WHO guidelines. A specially prepared color atlas of OML was used for lesion recognition and confirmation during the survey. Among the 35- to 44-year-old subjects, the overall prevalence of OML was found to be 13% in urban men, 6% in urban women, 15% in rural men, and 4% in rural women. The corresponding figures for the 65- to 74-year-olds were 22%, 12%, 26%, and 19%. Tongue lesions and white lesions were relatively common, but denture-related lesions were not. No malignancies or erythroplakia was observed. Age and gender were found to relate to the occurrence of OML. In elderly men, smoking was significantly (p < 0.05) associated with some white lesions and tongue lesions, and alcohol drinking was also associated with some white lesions. In conclusion, tongue lesions and white lesions were relatively common in men, but pre-cancerous lesions were not prevalent.published_or_final_versio

Healing responses following surgical/non-surgical treatment in residual periodontally-involved sites

Objective: The aim of this study was to evaluate the healing responses following surgical or repeated non-surgical treatment in residual pockets of previously non-surgically treated periodontitis patients. Methods: 12 female and 4 male subjects (mean age = 44.5 years) were recruited for this split-mouth, single-blinded study. Matched-paired-sites with residual probing pocket depth ≥6mm and bleeding on probing were selected in each patient. Presence of supragingival plaque (Pl%), bleeding on probing (BOP%), probing pocket depth (PPD) and probing attachment level (PAL) were recorded at baseline and 3 months after treatment. Test sites were selected randomly for repeated non-surgical debridement under local anaesthesia while control sites received surgical treatment. Results: Full-mouth Pl% decreased from 20% at baseline to 17% at 3 months and the BOP% decreased from 25% to 22%. Mean PPD reduction for test and control sites were 3.3mm and 3.1mm (p>0.05, paired t-test), mean PAL gains were 2.5mm and 1.7mm (p>0.05), and mean increases in recession were 0.8mm and 1.4mm (p<0.05). Conclusion: The healing responses in residual periodontally-involved sites following non-surgical or surgical treatment were similar and both treatment modalities were effective in PPD reduction and gain of PAL, but surgical debridement caused more recession.postprin

Designing problem-based curricula: The role of concept mapping in scaffolding learning for the health sciences

While the utility of concept mapping has been widely reported in primary and secondary educational contexts, its application in the health sciences in higher education has been less frequently noted. Two case studies of the application of concept mapping in undergraduate and postgraduate health sciences are detailed in this paper. The case in undergraduate dental education examines the role of concept mapping in supporting problem-based learning and explores how explicit induction into the principles and practices of CM has add-on benefits to learning in an inquiry-based curriculum. The case in postgraduate medical education described the utility of concept mapping in an online inquiry-based module design. Specific attention is given to applications of CMapTools™ software to support the implementation of Novakian concept mapping in both inquiry-based curricular contexts.published_or_final_versio

Are periodontal diseases risk factors for certain systemic disorders - What matters to medical practitioners?

Objective. To review recent data on the nature and pathobiology of periodontal infections and to elaborate how periodontal infections might increase susceptibility to some important systemic diseases and conditions. Data sources. Medline literature search and websites of the American Academy of Periodontology and American Medical Association. Study selection. Literature and data on periodontal diseases and their links to systemic diseases. Data extraction. Review of relevant information and data. Data synthesis. Periodontal diseases, including gingivitis and periodontitis, are among the most common infections of humans. They are induced by bacteria and bacterial products of dental plaque and are characterised by inflammatory destruction of tooth-supporting connective tissues and alveolar bone. A growing body of scientific evidence has shown that severe periodontitis may enhance susceptibility to certain important systemic diseases and conditions, for example, cardiovascular disease, diabetes mellitus, adverse pregnancy outcomes, and pulmonary infections. The clinical implications of the emerging specialty of periodontal medicine for dental and medical practitioners are postulated. Conclusions. Periodontal diseases may be risk factors for cardiovascular disease, diabetes mellitus, adverse pregnancy outcomes, and pulmonary infections. Dental and medical practitioners should be aware of the clinical implications of these inter-relationships and treat affected patients in collaboration for better oral and general health.published_or_final_versio
