Bruxism is defined as 'diurnal or nocturnal parafunctional activity including clenching, bracing, gnashing, and grinding of the teeth'. Bruxism and clenching are two of the most common contributing factors in patients with temporomandibular disorders and craniofacial pain disorders. Even though many studies report the high prevalence of bruxism, its cause is still not clear. Occlusal interference has been regarded as a major etiologic factor. Nowadays, psychological stress and sleeping disorders are generally regarded as major possible etiologic factors. More than likely, the cause is multifactoral and overlapping, which makes it difficult for the practitioner to apply comprehensive and effective management strategies. Although dentists and psychologists generally believe that effective treatment is best achieved with a better understanding of the etiology of a given disorder, for now treatment for this type of disorder must proceed without a clear understanding of etiology. To overcome this obstacle, evidence-based comprehensive management protocols based on accumulated scientific findings should be provided. In this presentation, epidemiology, etiology, and the characteristics of bruxism are reviewed. Diagnostic procedures and management strategies focused on occlusal appliances and behavioral approaches are also discussed.

The cause and mechanism of eye diseases are follow in biblography. The etiological factor of eye diseases are nearly caused by heat. It is important to distinguish deficiency and substance. In external etiologic factors wind-fever is most of all in six exogenous factors. In internal etiologic factors xu(deficiency) of kidney, blood and fire of seven emotions are lots. In factors other than the internal and external, eating greasy food and hyper-caloric food are a lot of case. In relation with the yin-yang andxu-shi, ther are a lot of eye diseases symptom as dark-dizziness due to the yin-xu of hepatic-kidney. According to eight principles of differentiation of syndromes, syndromes of exterior, heat, shi, almost fall into the category of yang and syndromes of interior, cold, xu, nearly fall into the category of yin. In interior treatment, inducing wind and clearing heat, using Qi and tonifying blood, tonifying and suing of hepatic-kid ney are useful and often used treatment.

Purpose: Salivation is considered to be an important factor in the control of halitosis, and the amount of salivation has been shown to be closely related to the level of hydration. The purpose of our study was to evaluate the relationship between dehydration and halitosis. Methods: Twenty healthy young females with no dental problems were recruited. All participants were induced to become dehydrated and then over-hydrated. After inducing each hydration state, the severity of hydration and halitosis factor (organoleptic scores, amounts of resting and functional saliva, gas examinations, and tongue coatings) were measured. Hydration statuses were graded as dehydration, normal, or over-hydration according to urine osmolality. This was a cross sectional study with a cross over design. Results: The dehydrated status was associated with higher organoleptic scores than the normal or over-hydrated status (1.75±0.75 vs. 0.87±0.63, and 0.65±0.53, respectively. p<0.05). Mean values of CH₃SH, (CH₃)₂S in portable gas chromatography for the dehydrated, normal, and over-hydrated status were 11.70±37.00, 6.75±13.50, and 2.80±5.87 nmol/mol, 10.50±15.59, 7.25±10.87, and 1.50±2.55 nmol/mol, respectively. p>0.05). (CH₃)₂S (r=0.410, p=0.009) showed a moderate positive correlation with dehydration status. The resting salivation rates were relatively lower for the dehydrated status than for the normal or overhydrated status (p>0.05), and tongue coating results were also higher for the dehydrated status (p>0.05). Conclusions: Dehydration status appears to be positively correlated with a low resting salivation rate and high portable gas chromatography results. This shows that dehydration might be an etiologic factor of halitosis.

Purpose: Bruxism is commonly considered a major risk factor for temporomandibular disorders (TMD), and the psychosocial factors had been one of the etiologic factor of bruxism. But there are still unsolved issues on the relationship between sleep bruxism and TMD and the etiologic factors of bruxism. This study is aim to evaluate the clinical and psychosocial characteristics according to diagnostic grade of bruxism in TMD patients. Methods: Three hundred subjects were enrolled who were under the stabilization splint therapy for TMD. Recently international consensus proposed a diagnostic grading system of "possible", "probable", and "definite" sleep or awake bruxism for clinical and research purpose. According to their suggestion, we classified these subjects as self-reported bruxism (SRB) and wear facet bruxism (WFB). We investigated the clinical characteristics (sex, age, chief complaint, pain duration, visual analogue scale), sum of tenderness (temporomandibular joint, masticatory muscles, cervical muscles), diagnosis of TMD according to research diagnostic criteria (the Research Diagnostic Criteria for Temporomandibular Disorders, RDC/TMD), headache, subjective sleep quality (Pittsburgh Sleep Quality Index, PSQI), and psychosocial characteristics (Symptom Checklist-90-Revised, SCL-90-R) in enrolled subjects. We compared the clinical and psychosocial characteristics between these bruxism groups. Results: There were no significant correlation between self-reported and WFB (p=0.13). SRB subjects more reported pain as a chief complain than subject who did not report bruxism (p=0.014). The mean score of global PSQI was significantly higher in SRB than in did not report positively subjects (p=0.045). The mean score of anxiety and phobic anxiety was significantly higher in SRB than in did not reported positively subjects (p=0.045, p=0.041). Conclusions: Although bruxism is regarded as risk factor of TMD, this study showed inconsistent result between SRB and clinically detected bruxism by wear facet on slpint. We suggest that the clinician should consider with extreme caution when they assess SRB.

Objectives Adhesive capsulitis (AC) is a restricted shoulder range of motion. Rotator cuff disease (RCD) has been believed to be a major etiologic factor of AC, however, how soon is the development time from RCD to AC (DTRA) has not been elucidated. The purpose of our study was to evaluate the correlation between the ultrasonographic characteristics of RCD and the DTRA. Methods Total 40 patients who were diagnosed as AC were recruited. The clinical characteristics of RCD were diagnosed by ultrasonography and classified with the Southern California Orthopedic Institute for Rotator Cuff Classification. The correlation was analyzed with Mann-Whitney U test and one-way analysis of variance. Results 60% of full thickness tear and 40% of partial thickness tear patients (10 male and 30 female, mean age of $54.0{\pm}8.4$ years) and 38% of bursitis and 21% of neovascularization were observed. The mean value of DTRA was $74.8{\pm}131.3$ days. There were no correlation between DTRA and gender (p=0.63), location of the partial tear (p=0.63), the severity of the partial thickness tear (p=0.63), full thickness tear (p=0.66) and completeness of the tear (p=0.16). The presence of bursitis or neovascularization was not associated with DTRA (p=0.60, p=0.61). Conclusions Although RCD is a major etiologic factor of AC, the severity, the type of RCD and the presence of bursitis and neovascularization were not statistically correlated with the DTRA in our study. Comprehensive consideration about etiologic factor analysis of AC will be needed with prospective study design for future study.

Background: The involvement of HPV in oral and oropharyngeal carcinogenesis was first proposed in 2004, based on epithelial HPV tropism and detection of HPV genotypes in oral squamous cell carcinoma samples. While 60-70% of oropharynx tumors may be HPV-positive, only 10 to 19% of tumors of the oral cavity, larynx and hypopharynx appear to have HPV infection. The aim of the study was to evaluate HPV infection associated with oropharyngeal cancer. Materials and Methods: Seventy-eight cases were selected for p16 immunoexpression reactions, and demographic data were collected for comparisons. Results: Most patients were over 60 years old, and 64.1% were smokers. Immunohistochemistry results showed that 86.3% of cases stained positive for p16 protein. Conclusion: The oropharyngeal cancer profile at Erasto Gaertner Hospital presented a high index of smokers over 60 years as well a high number of p16+ tumors, for what we can not determinate the main etiologic factor, but can be aware of the number of patients that presented HPV infection. Since prevention is still the best way to deal with cancer disease, it is important to analyze the interaction of these two etiologic factors and how to detect lesions at an early stage.
