The simple and easy treatment with cast or splint has been applied to stabilize long bone fractures in farm animals. Applying cast or splint is relatively easier than surgical fixation and may temporarily stabilize fracture site. However, the internal fixation provides strong stabilization and early recovery of limb function. In this report, we describe six cases of limb fractures in calves repaired by internal fixation. Fracture sites are various and affected ages are between 1 day and several months old. In some cases, patients were treated with cast or splint before admitting to Veterinary Medical Center. In these patients, regardless of initial treatment fractures were not immobilized. Consequently we decided to treat these patients with open reduction and internal fixation. The fracture repair with implants(bone plate, screw, cerclage wire, and intramedullary pin) were effective and satisfactory in calves which had been failed by application of cast. Although the cost of orthopedic treatment in farm animal is one of the most important considerations from the practical point of view, internal fixation has many benefits in newborn and young calves. And simplicity of postoperative management is also practically significant benefit expected from infernal fixation In conclusion, we suggest that internal fixation will produce better result than external coaptation in calve.

In the past, many dentist were interested mainly in the mechanical aspects such as tooth preparation and retainer types for making dental restoration. But, these days, the concept of restorative treatment emphasizes the importarce of gnatic system and masticatory muscles in addition to oral cavity. So, the current considerations for the fixed prosthodontic treatment include the stabilization of temporomandibular joint and neuromuscualr system and the relationship of periodontal ligament and occlusion. To achieve the above objectives, occlusal splint has been used as one of the mouth preparations for restorative treatment. The objectives of occlusal splint are as follows; 1. To use as preliminary application for periodontal-occlusal treatment 2. To provide proper vertical dimension 3. To control abnormal habits and parafunction 4. To treat the temporomandibular disease and myofascial pain 5. To establish the new therapeutic position In some cases, the patients had improper vertical dimension and occlusal interferences caused by prostheses reconstucted using centric relation recorded without considering the health of TMJ and manticatory muscle. And these prosthesis act as primary source that cause pathologic phenomenon in periodontal ligament, muscles and TMJ. Physiologically, in order to make the treatment occlusion guided by proper centric relation method, the method should be guided after the use of occlusal splint for some period. The main objective of prosthetic treatment is to maintain the function and health of stomatognathic system. So, one of the most important things that have to be performed by clinicians is a clinical ability to do the correct diagnosis and treatment planning based on the stomatognatic function and occlusion.

In order to evaluate the outcome of conservative treatment for acute or chronic closed lock, 127 patients were subjected at the Dept. of Oral Medicine, PNUH, from 1991. All the symptoms were analyzed and the results according to treatment modalities were compared before and after treatment. 1. Closed lock patients were more often seen in women of twenty and thirty. 2. The most common reasons for treatment were functional pain, limitation of mouth opening, restricted laterotrusion to non-effected side, deflection on opening but, on the contrary, noise was the least. 3. Most of closed lock patients were curedin six months. 4. Conservative treatment including stabilization splint produced better results. 5. Functional pain and limitation of mouth opening were relieved and maximumm comfortable opening was expanded, but joint noise decreased in the chronic and increased in the acute.

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.

In order to evaluate the effect of conservative treatment for Temporomandibular Disorders(TMD), 137 patients were subjected at the Department of Oral Medicine, Pusan National University Dental Hospital from June 2012 to Sept. 2012. They were treated conservatively with behavioral therapy, physical therapy, medication and occlusal stabilizing splint therapy. Subjective symptoms and clinical findings were investigated to evaluate and compare the patients' status after 3 months treatment. The results were as follows; 1. Pain, Noise, LOM(Limitation of motion) and MCO(Maximum comfortable opening) measurements of TMD were markedly improved after conservative treatments including behavior therapy, physical therapy, medication and splint therapy. 2. There was no difference in treatment outcomes after conservative treatments when the subjects were classified and compared according to gender and chronicity. 3. Conservative treatment including stabilization splint produced better results than physical therapy with medication. 4. After 3 months of treatment, pain and LOM were significantly improved in the MD(Muscle disorder) group. Pain, LOM and noise were significantly improved in the DD(Disc displacements) group. In the OA(Osteoarthritis) group, pain, noise, LOM and MCO were significantly improved.

The risk of temporomandibular joint disorder (TMD) can be increased during dental treatment due to excessive mouth opening and change of occlusion. The aim of this study is to find the relationship between dental treatment and TMD in the patients who developed TMD after dental treatment. The subjects of this study were 21 patients, who developed TMD after dental treatment and were treated with active TMD therapy in Seoul National University Bundang Hospital from June 2003 to February 2007. The subjects were examined with preceding dental treatment, symptom, diagnosis, treatment method of TMD and prognosis of TMD. The obtained results were as follows. 1. Preceding dental treatments were : Implant treatment, 14 cases ; Tooth extraction, 3 cases and others. 2. TMD symptoms were : pain on TMJ, 12cases : Sound on TMJ, 3cases ; Mouth opening limitation, Headache and others. 3. Diagnoses of TMD were : Synovitis and/or capsulitis, 10 cases ; 8 cases of Internal derangement and others. 4. Most TMD were treated by stabilization splint. 5. Prognoses of TMD were : Improvement, 6cases ; sustained 11 cases. In conclusion, the risk of TMD is increased during implant treatment. Prognoses of TMD after dental treatment were bad. It might be that these patients were non-cooperative and have distrust of dental treatment. Because the overloading on TMJ is possible in dental treatment of patients with underlying TMD, prior explanation and knowledge TMJ treatment are very important in these cases.

In this case report, I discussed the diagnosis and treatment of two pregnant women with temporomandibular disorders(TMD) who visited the Department of Oral Medicine, PNUH. Also, I reviewed some investigations of diagnosis and treatment of TMD in pregnant women. The obtained results were as follows; 1. No single X-ray diagnostic procedure for TMD results in radiation dose that threatens the well-being of the developing embryo and fetus. 2. Most non-steroidal anti-inflammatory drugs(NSAIDs) have commonly used because these drugs are considered to be nonteratogenic, but these agents are not recommended for routine use after 3rd trimester. 3. Electro-acupuncture stimulation therapy(EAST) is contraindicated for 1st trimester, and ultrasonic deep heat therapy, microwave deep heat therapy, low level laser therapy, myo-monitor are not contraindicated for pregnant women but clinician must consider some risk of adverse fetal effects. 4. The occlusal stabilization splint may be used for pregnant women, if it is fabricated indirectly. 5. Surgical treatment is contraindicated for pregnant women.

Severe dental attrition causes pathological changes of the tooth, collapsed occlusion, and functional and aesthetic complications and can also result in a decrease in occlusal vertical dimension. Before increasing the vertical dimension with full-mouth rehabilitation, it is important to determine the amount of vertical dimension through accurate diagnosis. In this case, a 77 year old elderly male patient on anticoagulant medication with generalized attrition and fracture of teeth was treated with full-mouth rehabilitation in order to recover vertical dimension and aesthetics. Accurate clinical and radiographic examination, diagnostic, wax-up, and occlusal vertical dimension evaluation were step by step performed considering pre-medical history and old age. Patient adaptability was evaluated using an occlusal splint and interim restoration. After 3 months of stabilization with interim restoration, definitive prostheses were fabricated. Satisfactory functional and esthetic outcomes are observed after 6 months of follow up.

The management of refractory pain and limitation of mouth opening in the temporomandibular joint (TMJ) is both challenging and controversial. Arthrocentesis is a simple technique and it can be used instead of more invasive surgical procedures for patients who failed to conventional conservative treatments. The patients in this case report had complained persistent severe pain and restricted mandibular movement of TMJ, although they had been treated with conservative therapy, e.g., stabilization splint therapy, behavioral therapy, physical therapy, pharmacological therapy. Therefore we employed arthrocentesis for these patients, and they showed significant reduction of pain and improvement of mandibular movement after repetitive arthrocentesis. We recommend arthrocentesis as an effective, minimally invasive technique for patients with continuing severe pain and restricted mobility in the TMJ that is unresponsive to conservative management.

From the point of view of oral rehabilitation, the treatment of extensive tooth wear requires a prosthetic approach. Physiological tooth wear is considered as a normal process and generally does not require treatment, but excessive tooth wear causes problems like inadequate occlusion and esthetics. Changes of occlusal vertical dimension should be made through accurate diagnosis and analysis. Also, the patient's adaptation to the changed occlusal vertical dimension should be assessed over time. This case was a 60-year-old male patient who complained of a decrease in chewing function and esthetics due to severe tooth wear. Full-mouth rehabilitation was performed with a tooth supported fixed prosthesis. An occlusal stabilization splint and provisional restoration were used to evaluate the adaptation to increased occlusal vertical dimension and induce a stable centric relation position. After that, monolithic zirconia prosthesis was delivered. We report this as a satisfactory functional recovery and esthetics.
