Background: To assess the clinical outcomes of short-term oral corticosteroid therapy for impingement syndrome of the shoulder and determine whether it can be substituted as an alternative to the intra-articular injection. Methods: The clinical outcomes of the 173 patients, the oral steroid group (n=88) and the injection group (n=85), were measured at 3 weeks, 2, 4, and 6 months postoperatively. The clinical outcomes were assessed by measuring the the University of California at Los Angeles (UCLA) score, visual analog scale (VAS) and range of motion (ROM) at every follow-up. Any complications and recurrence rate were noted. A relationship between the treatment outcomes and factors such as demographic factors, clinical symptoms and radiographic findings were determined. Results: No difference was observed in VAS and UCLA scores between the two groups, but forward flexion and internal rotation of ROM were significantly improved in the injection group at the 2nd and 4th postoperative month (p < 0.05). At 6th postoperative month, recurrence rate of symptoms was 26% in the oral steroid group and 22% in the injection group. No major adverse effects were observed. When the clinical outcomes of the oral steroid group were compared to either demographic, clinical symptoms, or radiographic findings, UCLA score was found to be significantly low (p < 0.05) in patients with joint stiffness and UCLA score, whereas VAS score was significantly improved in patients with night pain (p < 0.05). Conclusions: Short-term low-dose oral corticosteroid therapy of impingement syndrome showed comparable clinical outcomes to intra-articular injection without any remarkable adverse effects. Low-dose oral steroids can be regarded as a partial alternative to intra-articular injection for the initial therapy of impingement syndrome of the shoulder.

The diagnostic value of a intra oral film is related to projecting technic and interpretation. The intra-oral film is a single plane representation of a three dimensional object, therefore superimposition is inevitablly present. The purpose of this article is to show how foreign objects in the jaw may be localized. The author used double exposure technics, that are changed angulation of vertical or horizontal to one film. The obtained results are as fallow: 1. In the upper anterior region, the moving distance of the labially impacted reference object was greater than that of the palatally impacted one. 2. In the upper molar region, the moving distance of the mesiobuccal root apex was the greatest and that of palatal root apex was the shortest. 3. In the lower molar region, the change of the alveolar bone level in the buccal side was greater than that of lingual side.

A resorbable barrier membrane is commonly used for the repair of perforated sinus membranes during sinus lifting surgeries. However, repairing largescale perforations poses challenges for clinicians as the protection and isolation of graft material remain uncertain. With this technique, we aimed to prevent graft material loss and subsequent sinus-related complications using intra-sinus rigid fixation of the resorbable barrier membrane in cases with a large perforation of the sinus membrane.

It is clinically important to determine the physiologic mandibular position as the therapeutic position of the patients who needs the oral rehabilitation and occlusal treatment. Several methods have been employed for the recording the mandibular position. The gothic arch tracer is one of methods to record the mandibular position. The purpose of this study is to record the border position, chewing position, and myocentric position using the newly developed intra oral tracer in 10 subjects with TMJ clicking sound and 10 subjects without TMJ clinking sound.. This study showed that newly developed intra oral tracer allowed clinician the determination of the treatment position on the same horizontal plate which can be used in the full mouth rehabilitation and occlusal treatments. There was no statistically significant difference between clicking group and nonclicking group in the distance of border position-chewing position and the distance of border position-myocentric centric position.

The primary intra-osseous carcinoma (PIOC) is a very rare lesion. PIOC is an odontogenic carcinoma defined as a squamous cell carcinoma arisinig within a jaw having no initial connection with the oral mucosa, and presumably developing from residues of the odontogenic epithelium. The authors diagnosed a 51-year-old female as primary intra-osseous carcinoma after undergoing clinical, radiological and histological examinations. The characteristics were as followed : 1. The patient complained of gingival bleeding on the premolar area in the left maxilla 2. The conventional radiograms showed a relatively well-defined unilocular radiolucent lesion from the mesial aspect of the upper left canine to the mesial aspect of the upper left 1st molar. The 2nd premolar was separated from the 1st molar and the floor of the maxillary sinus was elevated by the lesion. There was a external root resorption of the upper left canine, the 1st premolar, and the 2nd premolar. 3. On the computed tomograms, the osteolytic bony lesion expanded the cortical plate of the left maxilla and displaced the margin of the left maxillary sinus upwards. But the bony lesion was separated from the maxillary sinus by a bony septum. 4. Bone scintigram with /sup 99m/Tc demonstrated the increased uptake in the left maxilla. Sonograms in the neck area and chest P-A radiogram didn't show any abnormalities. 5. Histologically, the tumor islands infiltrating into the surrounding bone increased in alveolar pattern, composed of the malignant cells, and there was a necrosis in the center of the tumor islands.

Mandibular chronic osteomyelitis with diffuse osteosclerosis is recognized as an intractable infectious disease. We emplyed decortication and intraarterial infusion of antibiotics in 6 cases. Decortication on the affected mandible was performed with retrocatherization to the superficial temporal artery of affected side under general anesthesia. Antibiotics, IPM/CS or FOMX was used through the artery for 4-11 days. In addition, we administered FOMX, PIPC intravenously for 8-17 days. CT and MRI were taken postoperatively. The postoperative follow-up period ranged from 1 year and 6 months to 2 years and 5 months. Postoperative MR showed that bone marrow signal was recovered to approximately normal in 4 cases. High signal area of bone marrow and osteosclerosis image remained in 2 cases, but showed improvement. The results were satisfactory without recurrence in all of 6 cases.

Purpose: The purpose of this study was to evaluate the internal fitness of prostheses fabricated with non-contact extra-oral scanner and those fabricated with intra-oral video scanner, with a comparative accuracy analyses of their precision and trueness. Methods: A polymethyl methacrylate (PMMA) model was fabricated by replicating a master model. The prostheses in the first group were fabricated based on the PMMA model with an intra-oral video scanner (IVS group). Following the fabrication of work models with Type IV Stone that were based on the PMMA model, the prostheses in the second group were fabricated with a non-contact extra-oral scanner (ENB group). The precision and trueness of the prostheses were calculated from comparisons of the three-dimensional images of the internal surfaces of the prostheses and those of the master model. Kruskal-Wallis tests were used to determine the statistical significance, with the level of type 1 error set at 0.05. Results: Trueness (P < 0.009) and precision (P < 0.001) did not differ significantly between the ENB and IVS groups. The IVS group exhibited lower trueness values and larger precision values than the ENB group. Conclusion: Although no significant differences were found in the internal fitness of the prostheses that were fabricated by the two different scanners, the intraoral video scanner-fabricated prostheses had better trueness, whereas the non-contact extra-oral scanner-fabricated prostheses had better precision.

The present report describes the case of a patient who underwent maxillary sinusitis right after dental implant installation with sinus lifting. Computed tomography scan revealed a dental implant (#16) was protruded inside the right maxillary sinus and confirmed the obstruction of ostium. A symptom remission was gained with the dual approaches combined by functional endoscopic sinus surgery and an intra-oral approach. Fully recovered function and healing of sinus were identified after 10 months follow-up. We report the case of sinusitis caused by protrusion of implants with sinus floor lift procedures and propose that practitioners should be aware of the possible its complications and management.

Burning mouth syndrome is characterized by intra-oral burning sensation without any organic abnormalities. This syndrome is associated with various etiological factors such as neuropathy, malnutrition, menopause and depression. Several medications have been tried for the treatment. Those are analgesics, hormones, anticonvulsants and antidepressants. However, optimal effective pharmacologic treatment remains still unknown. The purpose of this case study is to report the clinical effectiveness of gabapentin in the treatment of burning mouth syndrome in postmenopausal women with comorbid depression. We report two menopausal women. Antidepressants were effective for improving depressive symptoms, but it had no effects on intra-oral burning sensation. Gabapentin reduced intra-oral burning sensation effectively for all two patients. One patient reported 55% reduction(a decrease from 9 to 4 on VAS), the other patient reported 35% reduction(from 8 to 5) of the intra-oral burning sensation during 16 weeks. The minimal effective daily dose of gabapentin was 300mg. This study suggests that gabapentin might be a useful, effective therapeutic option for treating burning mouth syndrome in postmenopausal women with comorbid depression. Further prospective clinical studies are needed to investigate the effectiveness of gabapentin in patients with burning mouth syndrome.

The high success rate of dental treatment is dependent on the cooperation of pediatric patients during procedures. Dental treatment often causes pain, particularly in children. The factors in providing treatment to pediatric patients include the characteristics and location of the tooth, profoundness of the anesthesia including the type of local anesthetic, and cooperation of the patient. Previous studies have examined several techniques to successfully achieve profound pulpal anesthesia in maxillary permanent teeth. The dentist should select the injection technique to be used based on patient needs. In children, either buccal with palatal injections or buccal with intra-septal injections may be used to anesthetize the permanent maxillary first molar. Buccal with palatal injections are commonly used prior to routine maxillary dental procedures. Currently, there are only a few studies on the employment of buccal with intra-septal injections to anesthetize permanent maxillary first molars in pediatric patients. This review will focus on efficacy of buccal with palatal versus buccal with intra-septal pulpal anesthesia of the permanent maxillary first molars in pediatric patients and aim to determine which technique should be used during routine dental procedures.
