Objective To evaluate the effectiveness of joint mobilization combined with therapeutic exercise in patients with chronic anterior disc displacement without reduction of temporomandibular joints. Methods 46 patients with chronic anterior disc displacement without reduction were randomly divided into two groups. The treatment group of 24 cases received joint mobilization combined with therapeutic exercise and conventional therapy (ultrashort-wave diathermy, ultrasound therapy, soft tissue massage, health education), 22 cases in the control group received conventional treatment.The treatment was administered for 2 weeks. The baseline and endpoint outcome assessment measures were maximal interincisal opening (MIO),visual analogue scale(VAS)score and oral health impact profile (HIP-14). Results After the treatment, significant improvements were observed in the two groups of all the outcome measurements (P<0.05).Maximal interincisal opening, visual analogue scale and oral health impact profile were improved significantly in the treatment group than in the control group (P<0.05). Conclusion Joint mobilization combined with therapeutic exercise can improve the symptoms of chronic anterior disc displacement without reduction.

Objective Exploring the impact of establishing a tracking and management model for important abnormal results of health check ups based on quality control circle activities on improving telephone follow-up rates. Methods A total of 328 subjects with important abnormal results in Health Management Center of Sun Yat-sen Memorial Hospital of Sun Yat sen University from May 2022 to April 2023 were selected. The quality control circle activity group was set and the tracking management mode was carried out. The post intervention period was from November 2022 to April 2023, during which intervention measures 1-4 and comprehensive implementation measures were implemented for different samples. The number of successful follow-up after 1 month of follow-up was analyzed. Changes in the comprehensive ability of the circle staff before and after the intervention and the patients’ satisfaction with the health management center were compared. Results The telephone follow-up rate after intervention 1 was 85. 02%, 88. 59% after intervention 2,90. 23% after intervention 3,95. 27% after intervention 4 and 95. 80% after all intervention,which was higher than 75. 91% before intervention implementation. Among the single intervention individuals, the re-visit rate was 84. 34%（210/249）, and after the comprehensive implementation of measures, the re-visit rate among the successfully intervened individuals was 94. 74%（216/228）. After the intervention,the problem solving ability,responsibility, communication and coordination,team cohesion, enthusiasm,quality control techniques,self-confidence,and sense of harmony all significantly increased（P<0. 05）. The patient satisfaction rate before intervention was 85. 37%, and after intervention it was 87. 80%. The satisfaction rate increased after intervention, and the difference was statistically significant（P<0. 05）.
