TL;DR: The histopathologic features of 312 odontogenic keratocysts are described in this article in relation to their pathogenesis and behavioral characteristics, including recurrence factors and neoplastic potential.

TL;DR: The most significant factor in obtaining maximum results in root canal irrigation is the diameter of the canals, which seems to be a function of canal diameter rather than the type of solution used.

TL;DR: There were no appreciable histopathologic differences between the accessory gland and the main gland in the same facial half and Aging changes, such as decreased glandular elements, increased fat, and increased fibrous connective tissue, were not more extensive in the accessory glands than in the main glands.

TL;DR: The results indicated that obesity significantly contributed to the severity of periodontal disease and hyperplasia and hypertrophy of the walls of blood vessels supplying the periodontium in the hypertensive and obese-hypertensive animals.

TL;DR: In a 7-year follow-up study of 107 cases of oral epithelial dysplastic precancerous lesions in Indian villagers, 6.6 per cent were found to develop into carcinomas and clinical spontaneous regression occurred in 14.8 per cent.

TL;DR: This potential transformation alone does not justify radical treatment of all these benign lesions, but if there is recurrence accompanied by a histologic pattern change toward a more unorganized fibrous stroma with displacement of the epithelial component, then more extensive treatment procedures appear to be indicated.

TL;DR: Benign neural sheath neoplasms occurring centrally within the jaws are most uncommon, and generally present as asymptomatic radiolucencies, but some are associated with pain and/or swelling.

TL;DR: Because of its long-time use as a sedative or anodyne in dental procedures, eugenol was studied to determine its effect on evoked nerve impulse transmission.

TL;DR: It is suggested that the regular use of the African chewing stick, acting as an antiseptic, may control the formation and activity of dental plaque and therefore reduce the incidence of gingivitis and possibly dental caries.

TL;DR: The data presented suggested a trend toward decreased RAU prevalence and severity among physicians, dentists, veterinarians, and nurses as compared with 12 years previously when they were professional school students, and reduction in severity was observed in all groups.

TL;DR: Various open-bite and non-open-bite maxillary deformities in forty-one adults with the long face syndrome were corrected by Le Fort I osteotomy, orthodontic treatment, and restorative procedures.

TL;DR: Clinically, gingival metastatic lesions are most often confused with hemangioma, pyogenic granulomas, giant-cell granuloma, and pepripheral fibroma, and they usually occur late in the course of the disease and are associated with metastatic deposits in many other organs and tissues.

TL;DR: This study compared the osteogenic potential and tissue compatibility of biodegradable copolymers--PLA/PGA--and a biodesgradable ceramic--Ca3(PO4)2.

TL;DR: This study has been conducted on forty-five Asiatic skulls and sixty-two mixed skulls of black and white Americans to determine the anteroposterior relationship of the mandibular foramen.

TL;DR: Fourteen patients with chronic sclerosing osteomyelitis of the mandible were investigated with 99mTc-labeled bone-seeking agents and good agreement was found between radiography and scintigraphy concerning the extent and activity of each process.

TL;DR: In a 3-year review of 218 teeth with retrograde root filling with amalgam or Cavit, the results obtained with the former proved significantly better than those obtainedwith the latter, due to a better obliterating effect of amalgam.

TL;DR: A saliva substitute has been developed for use in veteran patients, primarity those undergoing radiotherapy for malignancy of the head and neck, which is high in calcium and phosphate.

TL;DR: The data strongly support the hypothesis of a genetic factor involved in susceptibility to the disease.

TL;DR: The sealing efficacy of temporary endodontic filling materials was tested in vivo and found that Cavit and Caviton show no or minor leakage in the vast majority of tests, while Gutta-percha showed gross leakage in six out of eight tests.

TL;DR: Oral atrophy may represent a preliminary stage of mucosal alteration that ultimately progresses to the clinical sequelae of stomatitis and oral ulcerations frequently encountered during cancer chemotherapy.

TL;DR: The results indicate that the use of a 175 ml.

TL;DR: In order to examine the aging of dentin and cementum, seventy-two impacted human canines, nonfunctional and not affected by external factors, including attrition, abrasion, caries, etc., were surgically extracted.

TL;DR: It is suggested that the term oral melanotic macule be used for these lesions, unless a specific cause can be confirmed by clinical data, and it would be prudent to remove them for histologic confirmation of clinical impressions.

TL;DR: Primary malignant smooth-muscle tumors of the mouth have rarely been reported and the age, sex, and site distribution of oral leiomyosarcomas are compared with those of oral Leiomyomas.

TL;DR: These two new surgical procedures add a new dimension to treatment of severe atrophy of the alveolar ridges in edentulous or partially Edentulous patients.

TL;DR: It is assumed that the now nonexistent plasma-cell gingivostomatitis syndrome was a hypersensitivity response to an unidentifiable antigen used in various substances.

TL;DR: Although treatment varied from physical therapy to intracranial condylectomy, the case of closed withdrawal of the condyle from the cranial fossa is the first case on record so treated.

TL;DR: The authors' experience with patients who have undergone extractions prior to radiotherapy indicates that exodontia may not be, within itself, associated with increased serious postirradiation sequelae, and a healing time of 10 to 14 days should be granted when teeth are extracted prior to irradiation.

TL;DR: A case of a benign synovial lesion of the temporomandibular joint, which was clinically thought to be a malignant parotid compartment tumor, showing histologic features of both pigmented villonodular synovitis andsynovial chondromatosis is reported.

TL;DR: Patients who had been involved in accidents with direct or indirect trauma to one or both joints showed a significantly higher proportion of nonresponse to therapy.
