For the study of the temporomandibular joint in rheumatoid arthritis 30 patients were selected who were diagnosed as rheumatoid arthritis through the clinical, radiographic examination and laboratory findings. Temporomandibular joint involvement was evaluated through the clinical, radiographic examination. The results were as follows; 1. TMJ was involved in 15 patients of 30 patients with rheumatoid arthritis. (50% involvement). 2. Duration of rheumatoid arthritis was more longer in patients with TMJ involvement than in patients without TMJ involvement. 3. Osseous changes in TMJ were in order of frequency erosion, flattening, osteophyte, sclerosis, deformity, and most common involved site was mandibular condyle. 4. Most common positional change of condyle was forward position in centric occlusion, and restricted movement of condyle in 1inch mouth opening. 5. TMJ involvement of rheumatoid arthritis was almost bilateral. 6. Main symptoms of TMJ were pain, stiffness, tenderness, limitation of mouth opening, crepitation 7. There was not the case of ankylosis. 8. There was statistically insignificant correlation between mandibular deviation and TMJ involvement, but some cases showed severe deviation on mouth opening.

Cherubism is an uncommon, benign fibrosseous lesion of the jaws that causes a progressive, painless, symmetrical expansion of the maxilla and mandible. It's autosomal dominance pattern of inheritance has been confirmed. A characteristic deformity is specific to this disease: hypertrophy of the mandible, swelling of cheeks and sometimes hypertrophy of maxilla with eyes tending to look up ; that looks like the Renaissance cherubs. It usually makes figures during childhood between 2-4 years of age and progresses until puberty, after which it spontaneously regresses 10 most cases. As a result of this case review, the management strategies for cherubismic children in standpoint of pediatic dentistry can be summarized as follows: 1. It can be detected early in childen through its characteristic clinical and radiographic features, which is confirmed by histopathological examination and familial history. 2. The supervision of arch space is required against its frequent sequelae, the early missing of primary teeth and eruption disorders of permanent teeth. 3. It is highly recommended to continue the periodic check-up with clinical and radiographic examination, leading to surgical intervention in cases of aggravation.

A 5-year-old, 6.2 kg male mixed dog was presented to local animal hospital with a 6-month history of swelling, pain, inflammation, and lameness in the 5th digit of right hind limb. And a 7-year-old, 2.7 kg male Maltese dog was also presented to animal hospital with a 2-month history of nail deformities in the 5th digit of left hind limb. Abnormal growth or degeneration of the distal phalanges was observed at the 5th digit of hind limb in two dogs using radiographic examination. The masses in the digit were excised completely under local anesthesia. On histological examination of the digit masses, large well-circumscribed, unencapsulated round or irregular cystic neoplasms with/without inflammation were occupied in or adjacent area of the distal phalanx. These cysts were lined by stratified squamous epithelium that occasionally had a prominent granular cell layer. Based on the history, clinical signs, radiographic, gross and histopathologic features, these cases were diagnosed as nailbed epithelial inclusion cysts in the digit of dogs.

Purpose: The purpose of this study was to evaluate the clinical efficacy of enhancing deficient interdental papilla with hyaluronic acid gel injection by assessing the radiographic anatomical factors affecting the reconstruction of the interdental papilla. Methods: Fifty-seven treated sites from 13 patients (6 males and 7 females) were included. Patients had papillary deficiency in the upper anterior area. Prior to treatment, photographic and periapical radiographic standardization devices were designed for each patient. A 30-gauge needle was used with an injection-assistance device to inject a hyaluronic acid gel to the involved papilla. This treatment was repeated up to 5 times every 3 weeks. Patients were followed up for 6 months after the initial gel application. Clinical photographic measurements of the black triangle area (BTA), height (BTH), and width (BTW) and periapical radiographic measurements of the contact point and the bone crest (CP-BC) and the interproximal distance between roots (IDR) were undertaken using computer software. The interdental papilla reconstruction rate (IPRR) was calculated to determine the percentage change of BTA between the initial and final examination and the association between radiographic factors and the reconstruction of the interdental papilla by means of injectable hyaluronic acid gel were evaluated. Results: All sites showed improvement between treatment examinations. Thirty-six sites had complete interdental papilla reconstruction and 21 sites showed improvement ranging from 19% to 96%. The CP-BC correlated with the IPRR. More specifically, when the CP-BC reached 6 mm, virtually complete interdental papilla reconstruction via injectable hyaluronic acid gel was achieved. Conclusions: These results suggest that the CP-BC is closely related to the efficacy of hyaluronic acid gel injection for interdental papilla reconstruction.

Purpose: Pycnodysostosis (PYCD), an autosomal recessive syndrome, is characterized by an imbalance in bone remodeling that produces various clinical and radiographic craniofacial manifestations. This review represents a systematic examination of these manifestations, as well as oral features associated with PYCD. Materials and Methods: A systematic review was conducted across 8 databases from February to March 2023. The search strategy focused on studies reporting cases of PYCD that examined the clinical and radiographic craniofacial and oral characteristics associated with this syndrome. Results: The review included 84 studies, encompassing a total of 179 cases of PYCD. More than half of the patients were female (55.3%), and the mean age was 14.7 years. Parental consanguinity was reported in 51.4% of the cases. The most common craniofacial clinical manifestation was a prominent nose, observed in 57.5% of cases. Radiographically, the most frequently reported craniofacial characteristics included the presence of an obtuse mandibular angle (84.3%) and frontal cranial bosses(82.1%). Clinical and radiographic examinations revealed oral alterations, with micrognathia present in 62.6% of patients and malocclusion in 59.2%. Among dental anomalies, tooth agenesis was the most commonly reported, affecting 15.6% of patients. Conclusion: Understanding the clinical and radiographic craniofacial features of PYCD is crucial for dental professionals. This knowledge enables these clinicians to devise effective treatment plans and improve patient quality of life.

The conventional osseointegration protocol calls for waiting up to 12 months for ossification of an extraction socket to heal before placing an endosseous implant. In this study, the possibility of placing a pure titanium implant directly into an extraction socket immediately after extraction was investigated. And the marginal bone loss of immediate nonsubmerged and submerged endosseous dental implants placed into extraction sockets was also compared. Pure titanium Nobelpharma Branemark implants and solid screw type ITI implants were placed into premolar extraction sockets of two adult dogs and allowed to heal for a period of 3 months, followed by functional loading of the implant. Radiographic examination was performed before implantation, immediately after implantation and 3, 6, 9, 12 months after implantation. The results obtained were as follows : 1. Immediately placed nonsubmerged ITI implants and submerged Branemark implants showed favorable radiographic osseointegration status and there were minimum marginal bone loss. 2. There were no significant differences in radiographic finding of osseointegration between conventional and immediate implantation. 3. Gingival tissue around implants showed more inflammatory signs than that of adjacent natural teeth. This study suggest that pure titanium Branemark implants and submerged ITI implants have the potential to integrate when placed immediatly after extraction of the teeth and warrants further investigation.

Radiographic left atrial dimension (RLAD) is a useful measurement to assess left atrial enlargement in dogs. There are studies on the use of RLAD on various breeds of dogs, but no study on a specific breed with myxomatous mitral valve disease (MMVD). This study was conducted to compare RLAD measurements in Maltese dogs with MMVD ACVIM stage B1 and B2, and also to investigate the correlation of RLAD with the LA:Ao ratio. A total of 29 Maltese dogs were the subjects of this study. Each dog was diagnosed with MMVD ACVIM stage B1 or B2 based on physical examination, thoracic radiography, and echocardiography. The vertebral heart size (VHS), RLAD, LVIDDn, and LA:Ao ratio were measured and compared to evaluate the differences. There were significant differences in the RLAD, LVIDDn, and LA:Ao ratio between dogs with MMVD ACVIM stage B1 and those with stage B2. There was a significant correlation between the LA:Ao ratio and both the RLAD and VHS measurements, but the correlation coefficient was higher for RLAD. The RLAD scores exhibited a significant difference between dogs with ACVIM Stage B1 and with those with B2, and these scores had a higher correlation with the LA:Ao ratio measured by echocardiography than with VHS.

A 12-year old neutered male Yorkshire terrier dog was presented to the Veterinary Medical Teaching Hospital of Seoul National University with a history of chronic intermittent diarrhea, vomiting, anorexia and weight loss of 2-months duration. On presentation, he was very cachexic and had ascites. Abnormal findings on a complete blood count and chemistry profile included mild anemia, leukocytosis, panhypoproteinemia, hypocholesterolemia, decreased blood urea nitrogen (BUN) and increased serum bile acids. Radiographic findings indicated microhepatica. Peritoneal fluid analysis was consistent with transudates (total protein < 2.5 g/dl, total nucleated cell count = 2,200/ul) and cytologic examination of the fluid revealed neoplastic lymphoblasts. From these findings hepatic dysfunction and protein-losing enteropathy were attributable to abdominal lymphoma. This case suggests that cytologic examination is important in diagnosing underlying diseases of ascites, even if it is transudative effusion.
