Infection of surgical wounds is a severe problem. Conventional tissue reattachment methods have limits of incomplete sealing and high susceptibility to infection. Medical adhesives have several advantages over traditional tissue reattachment techniques, but still have drawbacks, such as the probability of infection, low adhesive strength, and high cytotoxicity. Recently, a new medical adhesive (new-adhesive) with high adhesive strength and low cytotoxicity, composed of aldehyded dextran and ${\varepsilon}$-poly(L-lysine), was developed. The antimicrobial activity of the new-adhesive was assayed using agar media and porcine skin. In the agar diffusion method, inoculated microorganisms that contacted the new-adhesive were inactivated, but this was not dependent on the amount of new-adhesive. Similar to the agar media results, the topical antimicrobial effect of new-adhesive was confirmed using a porcine skin antimicrobial assay, and the effect was not due to physical blocking based on comparison with the group whose wounds were wrapped.

PURPOSE. The purpose of this study was to achieve more retention and stability and to delay or prevent screw loosening. MATERIALS AND METHODS. Twenty implants (Implantium 3.4 mm, Dentium, Seoul, Korea) were divided into 2 groups (n = 20). In the first group, an adhesive material was applied around the screw of the abutments (test group). In the second group, the screws are soaked in saliva (control group). All the screws were torqued under 30 N/cm, Then, the samples were gone through a cyclic fatigue loading process. After cyclic loading, we detorqued screws and calculated detorque value. RESULTS. In comparison with the control group, all the implant screws in the test group were smeared with the adhesive material, showing significant higher detorque value. CONCLUSION. There are significantly higher detorque values in the group with adhesive. It is recommended to make biocompatible adhesive to reduce screw loosening.

Objectives: The aim of this study was to evaluate the effects of tri-antibiotic paste (TAP) on microtensile bond strengths (MTBS) of dental adhesives to dentin. Materials and Methods: Sixty extracted molars had their occlusal surfaces flattened to expose dentin. They were divided into two groups, i.e., control group with no dentin treatment and experimental group with dentin treatment with TAP. After 10 days, specimens were bonded using self-etch (Filtek P90 adhesive) or etch-and-rinse (Adper Single Bond Plus) adhesives and restored with composite resin. Teeth were sectioned into beams, and the specimens were subjected to MTBS test. Data were analyzed using two-way ANOVA and post hoc Tukey tests. Results: There was a statistically significant interaction between dentin treatment and adhesive on MTBS to coronal dentin (p = 0.003). Despite a trend towards worse MTBS being noticed in the experimental groups, TAP application showed no significant effect on MTBS (p = 0.064). Conclusions: The etch-and-rinse adhesive Adper Single Bond Plus presented higher mean bond strengths than the self-etch adhesive Filtek P90, irrespective of the group. The superior bond performance for Adper Single Bond when compared to Filtek P90 adhesive was confirmed by a fewer number of adhesive failures. The influence of TAP in bond strength is insignificant.

To evaluate the micro-shear bond strength of current adhesive systems to cervical and mid-coronal enamel. Materials and Two commercially available resin adhesives were investigated; a self-etching primer system(Clearfil SE Bond, Kyraray) and a one-bottle adhesive system(Single Bond, 3M) intended for use with the total-etch wet-bonding technique were employed. Two regions of enamel, cervical and mid-coronal regions, were chosen from the buccal surface of extracted molars and were then bonded with each adhesive system and submitted to the micro-shear bond test.(중략)

If autogenous nail is lost in nail bed injuries, alternative effective nail bed protection material is questionable in postoperative follow up period. The conventional modality with autogenous nail coverage have several disadvantages such as drawback of maintenance, higher chance of loss and complex dressing step (eg. ointment apply for humidification and nail fixation using tape or bandage). So, we have studied the usefulness of adhesive silicone gel sheet for alternative nail bed protection material until the end of nail regeneration. From March 2003 to July 2004, we have experienced 215 traumatic nail bed injuries except fingertip loss. Among these patient, we classified two groups, 30 cases with autogenous nail protection(Group I) and 30 cases with adhesive silicone gel sheet protection(Group II). Mean full nail growth time was 3.6 months in group I and 3.8 months in group II. Mean final nail appearance score(0: poor, 4: excellent) was 3.0 in group I and 3.5 in group II. Adhesive silicone gel sheet protection(Group II) was slightly superior to the autogenous nail protection in final appearance, especially sterile matrix laceration. In conclusion, we believe that adhesive silicone gel sheet application is a simple, acceptable, alternative method for protecting nail bed with loss of autogenous nail. It has a number of advantages compared with autogenous nail such as better humidification, controllable hygiene, less pain, less hospitalization, less frequent visit, less chance of loss, avoiding complex dressing step and more even pressure with adhesiveness, flexibility and durability.

Adhesive capsulitis of the shoulder joint is a common disease characterized by pain at the insertional area of the deltoid muscle and decreased range of motion. The pathophysiological process involves fibrous inflammation of the capsule and intraarticular adhesion of synovial folds leading to capsular thickening and contracture. Regarding the multidirectional limitation of motion, a limitation in external rotation is especially prominent, which is related to not only global fibrosis but also to a localized tightness of the anterior capsule. Ultrasound and magnetic resonance imaging studies can be applied to rule out other structural lesions in the diagnosis of adhesive capsulitis. Hydraulic distension of the shoulder joint capsule provides pain relief and an immediate improvement in range of motion by directly expanding the capsule along with the infusion of steroids. However, the optimal technique for hydraulic distension is still a matter of controversy, with regards to the infusion volume and rupture of the capsule. By monitoring the real-time pressure-volume profile during hydraulic distension, the largest possible fluid volume can be infused without rupturing the capsule. The improvement in clinical outcomes is shown to be greater in capsule-preserved hydraulic distension than in capsule-ruptured distension. Moreover, repeated distension is possible, which provides additional clinical improvement. Capsule-preserved hydraulic distension with maximal volume is suggested to be an efficacious treatment option for persistent adhesive capsulitis.

Background: The purpose of this study was to evaluate the effect of single blinded anterior intra-articular corticosteroid injection to the glenohumeral joint performed by short experienced clinicians in frozen state adhesive capsulitis patients. Methods: From March to June of 2013, among the patients who visited the shoulder outpatient clinic due to shoulder pain for 5-6 months and those patient diagnosed as frozen state adhesive capsulitis was selected. The diagnosis were based on base, first the global limitation of range of motion, defined as forward elevation <100, external rotation at side <10, internal rotation less than buttock, and abduction <70. Second, the patients had additional radiologic evaluations showing no major pathologies for such stiffness. Clinical outcome, were performed with pain visual analog scale (PVAS) and functional visual analog scale (FVAS), American Shoulder and Elbow Surgeons Shoulder score (ASES), preinjection and postinjection after 2-4 weeks. Finally 82-patients were enrolled. Mean age of the patients was 55.1 years and mean follow-up duration was 25.17 days. Results: The mean preinjection PVAS was 6.91 and postinjection was 3.11, there was 3.8 decreases from preinjection status (p < 0.001). The mean FVAS score showed 4.26 at preinjection and 6.63 afterwards (p < 0.001). The ASES score showed 27.89 increases after injection (p < 0.001). There were 64-patients (78.04%) who reported more than 3 points of decrease of PVAS, who could be judged as effective treatment. Conclusions: Single anterior glenohumeral steroid injection by short experienced clinicians to the patients with frozen state adhesive capsulitis has shown relatively high efficacy in clinical result evaluated by means of PVAS.

Purpose: This experimental study aimed to solve the problem of discomfort and stably fix the bandage. A new self-adhesive bandage was manufactured to reduce the inconveniences associated with the plaster bandage. We compared the associated stability between the plaster bandage and the new self-adhesive bandage. Methods: The traditional elastic bandage (traditional EB; i.e., plaster bandage) and modified elastic bandage (modified EB; i.e., new self-adhesive bandage) were applied to 30 people each. We measured the time of preparation and attachment for traditional TB and attachment for modified TB. A 4kg cattle bell was fixed to each bandage to compare their respective stability levels. Results: The speed for the traditional EB was 28.93(±9.28)sec (mean 25.56s) and 6.13(±1.81)sec for the modified EB (mean 5.95sec). The stability values were 1.49(±.77)min for the traditional EB (mean 1.31min) and 26.22(±9.04)min for modified EB (mean 1.31min). The differences in speed and stability were statistically significant. Conclusion: Compared to the traditional EB, applying the modified EB could solve the attachment inconvenience and provide stable maintenance.
