Objective To investigate the level and influencing factors of oral health-related quality of life in patients with chronic periodontal disease. Methods 280 patients with chronic periodontal disease were investigated, using Pearson, Spearman correlation and multivariate linear regression to identify influencing factors of oral health-related quality of life. Results The oral health impact profile was in the middle level with a total score of 16.93±7.37. The influencing factors were self-efficacy for self-care, dental fear and entering into supportive periodontal therapy, which contributed 24.0% of the variance. Conclusions The oral health-related quality of life in patients with chronic periodontal disease is in low level. In order to improve the oral health-related quality of life in patients with chronic periodontal disease, health care providers should strengthen patients′ self-efficacy and reduce the patients′dental fear.

Objective To investigate the current status and influencing factors of self-efficacy for oral self-care in patients with chronic periodontitis. Methods A total of 357 patients with chronic periodontitis were investigated with the self-designed questionnaire, Self-Efficacy Scale for Self-care (SESS), Dental Fear Scale(DFS) and Medical Coping Modes Questionnaire(MCMQ). Results The total score of SESS was(58.66±7.27)points,which was at the medium level.In the scores of each dimension, self-efficacy for dietary habits was the highest,(20.42 ± 2.88)points,and self-efficacy for brushing of the teeth was the lowest,(18.37 ± 2.94)points.Multiple linear regression analysis showed that age,dental fear and medical coping mode were influencing factors of self-efficacy for oral self-care,which explained 53.6% of the variance. Conclusions Medical staff should pay more attention to the patients who are in low level of self-efficacy for self-care.Oriented by each dimension and influencing factors,specific psychological intervention should be given to reduce dental fear,improve medical coping style,enhance the level of self-efficacy for oral self-care and promote oral self-care behaviors and somatopsychic health.

Risk assessment of periodontitis can identify high-risk groups, predict individual periodontitis status, and contribute to periodontitis disease management. Therefore, the current review of several foreign periodontitis risk assessment systems provides a guide for clinical selection of periodontitis risk assessment systems.

Objective To explore the development trend and understand the development dynamics through research and analysis of factors influencing caries of preschool children in China,and provide reference and basis for the establishment of disease prevention and control strategy. Methods Based on the theme of dental caries or cavities or caries and factors or cause or reason and children ,the literatures were searched from CNKI, VIP Chinese science, technology database and Wanfang medical academic database and CBM from building to March 2018. The literature of preschool children caries disease factors, adopts the method of literature metrology analysis. Results A total of 303 literatures were detected, which were distributed in 165 journals and 40 core journals, accounting for 24.2% of the total number of periodicals. 28 articles were published in guangdong province, ranking the first. From building to March 2018, the number of posts has been increasing year by year;Fund funding started in 2003 and started late, but gradually increased after 2003.Tooth brushing, age, and sweets (snacks) are the three main causes of caries in preschool children. Conclusion The study on the factors affecting the caries of preschool children in China started late and may not be further studied due to the limitations of various conditions before 2000.In the last 10 years, the analysis of the factors affecting the dental caries of preschool children has been gradually deepened, and the number of publications has increased significantly.

Temporomandibular joint disorder (TMD) is one of the common diseases in stomatology caused by a variety of factors, with a high incidence rate, especially among the young people with great pressure, and difficult to treat this disease. it was easy to relapse directly affects the physical and mental health and quality of life of the patients. Psychological factors had been proved to be one of the causes of temporomandibular joint disorder, and cognitive behavioral therapy was a form of psychological therapy that has been applied to a variety of problems, including mental illnesses such as depression, anxiety, and physical symptoms like pain. Cognitive behavioral therapy (CBT) was also used in stomatology department. This paper reviewed the origin, concept formation, theory formation, characteristics and application of CBT in TMJ disorders, in order to provide more evidence for clinical practice and reduce pain for patients.

Objective To investigate the characteristics of peroperative blood pressure and heart rate in patients with normotensive incidental pheochromocytomas in order to provide the basis for peroperative treatment. Methods This retrospective study collected the data of 104 patients with a pathological diagnosis of unilateral pheochromocytoma at PLA General Hospital during January 2011 to December 2016. They were divided into normotensive incidental pheochromocytomas(NIP) group (n＝50) if the patients were normotensive and HIP group ( n＝54) if the patients were with hypertension. The clinical features, imaging features and peroperative hemodynamics were analyzed. Results ( 1) The age, urinary norepinephrine, daily dosage and duration of phenoxybenzamine in NIP group were less than those of HIP group (all P<0.05). (2) Preinduction blood pressure, maximum blood pressure, and total fluid intake in NIP group were lower than those in HIP group(all P<0.05). The blood pressure range, heart rate range, increased blood pressure, minimum mean arterial pressure, vasoactive medication were without statistical significance between these two groups. ( 3) The times and rate of intraoperative systolic blood pressure more than 30% baseline, 200 mmHg (1 mmHg＝0.133 kPa), 180 mmHg, 160 mmHg, intraoperative tachycardia, bradycardia, intraoperative hypotension and postoperative hypotension were without statistical significance between these two groups. (4) Stratified analysis of age (50 years), phenoxybenzamine (40 mg/d), tumor diameter (50 mm) and preinduction blood pressure (130/80 mmHg) showed that intraoperative blood pressure and heart rate were without statistical significance between these two groups. ( 5) There was no correlation between phenoxybenzamine ( daily dosage or duration ) and peroperative hypotension. Applying phenoxybenzamine or vasoactive medication was not correlated with peroperative hypotension in NIP group. Conclusion The peroperative blood pressure and heart rate of patients with NIP are similar to those of patients with HIP. Adequate peroperative treatment should be applied to NIP to avoid hemodynamic instability.

Objective:To evaluate the efficacy of combining modified manipulative reduction with functional training for the treatment of acute anterior disc displacement without reduction.Methods:Sixty anterior disc displacement patients aged from 19 to 55 years were randomly divided into an experimental group and a control group, each of 30. The experimental group was given modified manipulative reduction, while the control group was provided with traditional manipulative reduction. After the manipulative reduction, both groups received 3 months of functional training. Visual analog scale (VAS) ratings, maximum active mouth opening, a mandibular movement index and magnetic resonance imaging (MRI) were employed before and immediately after the reduction and after the functional training to evaluate their effectiveness. An oral health-related quality of life scale was also used. The number of attempts needed to achieve successful reduction and the overall success rate were compared between the two groups.Results:There was significant improvement in the average VAS ratings, maximum active mouth opening, mandibular movement index and oral health-related life quality of both groups after the experiment. Immediately after reduction, the maximum active mouth opening and mandible movement in the experimental group were significantly higher than in the control group, on average. Further improvement was observed after the treatment such that there was no significant difference between the two groups. After the functional training, however, the experimental group′s average VAS and oral health-related life quality scores were significantly better than the control group′s averages. According to MRI right after reduction, the success rate of the experimental group (96.7%) was significantly better than among the control group (80%). After the functional training the corresponding values were 86.7% and 73.3%. That difference was no longer significant. There was also no significant difference in the number of attempts needed to achieve successful reduction.Conclusion:The modified manipulative reduction not only has a higher success rate, but also can immediately improve mouth opening and mandible mobility. Combined with functional training, it can effectively reduce pain and improve life quality.
