This study was aimed to evaluate the effects of ultrasonic vibration on margin types and cements by comparing bond strength of cemented crown. In this study, margins of each metal die, which were chamfer, shoulder and shoulder with bevel, were prepared using computer milling machine. Specimens were cemented with zinc phosphate cement or resin cement. The specimens were divided by the finish line and cement used, ultrasonic vibration. I made total 84 specimens. All specimens were divided into two groups. One group was not vibrated, the other group was subjected to ultrasonic vibration for 12 minutes. Tensile bond strength was measured using Universial testing machine. The changes of bond strength in groups were statistically analyzed by t-test or One-way ANOVA. The results were as follows : 1. Ultrasonic instrumentation diminished the bond strength of crown cemented with zinc phosphate cement and resin cement after 12 minutes application. 2. In case of zinc phosphate cement, the bond strength of a vibrated group was showed significantly decreased(p<0.05). In vibrated groups with zinc phosphate cement, shoulder with bevel exhibit a significant difference to chamfer and shoulder(p<0.05) 3. Resin cement was more resistant to ultrasonic vibration than zinc phosphate cement and showed no significant differences according to ultrasonic vibration and margin type. In conclusion, These results revealed that zinc phosphate cement was most affected and resin cement was the least affected by ultrasonic vibration. Especially shoulder with bevel design was most affected in zinc phosphate cement groups. we should consider these results and be taken in the application of ultrasonic vibration to any teeth restored with crowns.

Background: To evaluate the clinical outcomes and associated repair integrity in patients treated with arthroscopic repair for a transtendinous rotator cuff tear followed by resection of the remnant rotator cuff tendon. Methods: Between July 2007 and July 2011, we retrospectively reviewed patients who were treated for transtendinous full-thickness tears in the tendinous portion of the rotator cuff by arthroscopic repair. Clinical outcomes were evaluated using the American Shoulder and Elbow Surgeons (ASES) score, the Shoulder Rating Scale of the University of California at Los Angeles (UCLA), the Constant-Murley score, a visual analogue scale (VAS) pain score, and range of motion (ROM). The repair integrity was determined by magnetic resonance imaging or ultrasonography. Results: There were 19 shoulders with transtendinous full-thickness tears in the tendinous portion of the rotator cuff. The ASES, UCLA, Constant-Murley, and VAS pain scores showed significant improvements in function and symptoms (all p<0.001). The active ROM for forward flexion and abduction was also significantly improved (p=0.002 and p<0.001, respectively). The postoperative radiological examination showed cuff integrity without a re-tear in 68.4% of patients. However, the UCLA, ASES, and Constant-Murley scores were not significantly different between healed and re-torn group (p=0.530, p=0.885, and p=0.262, respectively). Conclusions: Although repair of transtendinous rotator cuff tears followed by resection of the remnant rotator cuff tendon in the footprint has a relatively high re-tear rate, no significant difference was observed in the short-term clinical results between the re-tear and healed groups.

Background: To determine the prevalence of rotator cuff diseases in a population older than 40 years in or nearby Chuncheon city, Republic of Korea. Methods: Sixty shoulders of 30 people older than 40 years who participated in a health lecture were examined for free by an orthopedic surgeon. Visual analog scale of pain and American Shoulder and Elbow Surgeons scores were assigned, and routine physical examination was performed. Ultrasonography was performed on the shoulder. Results: On ultrasonographic examination, there were one shoulder with full thickness rotator cuff tear, 20 of 60 (33%) with partial thickness rotator cuff tear, five of 60 (8%) with calcific tendinitis, one of 60 (2%) with tear of the long head of the biceps, and five of 60 (8%) with tendinitis of the long head of the biceps. Participants older than 60 years showed significantly high proportions of lesion of the long head of the biceps and rotator cuff diseases (P=0.019 and P=0.015, respectively). Participants who performed physical labor had high proportions of rotator cuff tear and rotator cuff disease (P=0.001 and P<0.001, respectively). Conclusions: Rotator cuff diseases showed a high prevalence in aged persons and resulted in a decrease in shoulder function.

Background: This study was undertaken to evaluate early clinical outcomes of ultrasound-guided suprascapular nerve block (SSNB) using a proximal approach, as compared with subacromial steroid injection (SA). Methods: This retrospective study included a consecutive series of 40 patients of SSNB and 20 patients receiving SA, from August 2017 to August 2018. The visual analogue scale (VAS), American Shoulder Elbow Surgeon's score (ASES), University of California, Los Angeles score (UCLA), the 36 health survey questionnaire mental component summary (SF36-MCS), physical component summary (PCS), and range of motion (forward elevation, external rotation, and internal rotation) were assessed for clinical evaluations. Results: Compared with the baseline, VAS, and ranges of motion in the SSNB group significantly improved at the 4-week follow-up (VAS scores improved from $6.7{\pm}1.6$ to $4.3{\pm}2.4$, p<0.001; all ranges of motion p<0.05), while other variables showed no statistically significant differences. All clinical variables were significantly improved in the SA group (p<0.05). However, all clinical scores at the 4-week follow-up showed no significant difference between groups. Conclusions: Ultrasound-guided SSNB using proximal approach provides significant pain relief at 4-weeks after treatment, with statistically significant difference when compared with SA, suggesting that SSNB using proximal approach is a potentially useful option in managing shoulder pain. However, in the current study, it was less effective in improving shoulder function and health-related quality of life, compared with SA.

Background: This study investigated the clinical effectiveness of Korean medicine (KM) treatment for shoulder impingement syndrome (SIS). Methods: There were 61 patients who were diagnosed with SIS in the Jaseng hospital network of KM (7 hospitals located in Korea: Gangnam, Daejeon, Bucheon, Haeundae, Bundang, Ulsan, and Gwangju) between January 1^st, 2015 and December 31^st, 2020 who were retrospectively reviewed. The patients were grouped according to complications, intake of analgesics, duration of illness preadmission, and treatment. Treatments consisted of herbal medicine, acupuncture, cupping, Chuna, pharmacopuncture, bee venom pharmacopuncture, medicinal steaming, Daoyin exercises, and physical therapy. By comparing the Numeric Rating Scale (NRS), Shoulder Pain and Disability Index, and European Quality of Life 5-Dimensions questionnaire scores, the effectiveness of integrated KM treatment was evaluated. Results: There were 14 males and 47 females. For inpatients diagnosed with SIS, the mean NRS score decreased from 5.78 ± 1.33 to 3.40 ± 1.43 (p < 0.001). The mean Shoulder Pain and Disability Index score decreased from 53.87 ± 14.76 to 38.56 ± 18.87 (p < 0.001), and the mean European Quality of Life 5-Dimensions questionnaire increased from 0.67 ± 0.13 to 0.76 ± 0.09 (p < 0.001) after KM treatment. Medicinal steaming (0.398; p < 0.001), acupuncture (0.290), cupping (0.288), bee venom pharmacopuncture (0.282), and Daoyin exercises (0.262; p < 0.05) had a positive correlation with improved changes in the NRS score. Conclusion: Conclusion: Treatment with integrated KM treatment improved the pain, range of motion, shoulder function, and quality of life of patients with SIS.

Background: This study aimed to determine the impact of complex decongestive therapy applications on upper extremity function in breast cancer patients who developed adhesive capsulitis after lymphedema. Methods: Thirty patients who developed adhesive capsulitis due to lymphedema were divided into two groups as study (n = 15) and control (n = 15) groups. Both groups received 20 minutes of exercise five days a week for three weeks using a Biodex isokinetic dynamometer, as well as a hot pack and TENS (Transcutaneous Electrical Nerve Stimulation) treatment to the shoulder joint. The study group received 45 minutes of intensive decongestive therapy along with the adhesive capsulitis treatment. The visual analogue scale was used to assess pain, circumference, and volumetric measurements were used to assess edema, and the Arm, Shoulder, and Hand Problems Questionnaire (DASH: Disabilities of the Arm, Shoulder, and Hand) was used to assess upper extremity functionality. The shoulder range of motion was evaluated. Results: Both groups had improvements in pain (P < 0.001), shoulder joint range of motion (P < 0.001), and upper extremity functionality (P < 0.001) after the treatment. There was a significant decrease in circumference and volumetric measurements in the study group (P < 0.001). However, no differences were seen in measurements in the control group. Conclusions: The results showed that complex decongestive therapy was beneficial in reducing lymphedema in breast cancer patients who acquired adhesive capsulitis due to lymphedema. Consequently, the authors believe that supplementing conventional physiotherapy with complex decongestive therapy will benefit patients.
