Proliferative periostitis of Garré: its differentiation from other neoperiostoses.

A review of 15 well-documented cases of proliferative periostitis reported in the literature and a description of six new cases, five fully documented, have shown the following: a variety of irritants both odontogenic and nondontogenic in origin may induce neoperiostosis in the mandible; radiographically, cortical redundancy and preservation of the original cortical outline are the most common findings; and microsocopically, a fibro-osseous pattern evincing one of the three trabecular orientations--parallel, retiform, or haphazard fibrous dysplasia-like--is featured. If other complicating factors are absent, after the suspected source of irritation has been eliminated, resolution takes place in six to 12 months in most instances.

Programmed instruction in general pathology: evaluation of performance in comparison to conventional instruction and scholastic achievement.

Previous studies relating the efficacy of various teaching methods to student achievement levels have yielded conflicting results. This study compares programmed instruction in pathology with conventional instruction for students exhibiting different levels of academic achievement, as measured by undergraduate GPA. The results of this study reveal that no significant difference in examination performance exists regardless of the teaching method employed when achievement level is considered.

Sebaceous choristoma of the thyroglossal duct.

The presence of sebaceous glands within the oral mucosa is not uncommon. Such Fordyce granules are frequently seen on the buccal mucosa and lips, as well as in the retromolar area, gingiva, and palate. Whereas sebaceous elements are rarely encountered on the tongue, three cases of ectopic sebaceous glands have been reported in association with apparently patent thyroglossal ducts. An interesting case of a previously unreported sebaceous choristoma of the thyroglossal duct is described.

Aggressive growth and neoplastic potential of odontogenic cysts: with special reference to central epidermoid and mucoepidermoid carcinomas.

An aggressive form of odontogenic cyst known as the keratocyst has been reviewed with a report on the findings of 70 new instances. Recurrence after 2 years of followup was found to be 20%. From both a review of the literature and original cases, carcinomatous and ameloblastomatous transformation in odontogenic keratocysts seems to be an extremely rare phenomenon. Alternatively, epidermoid carcinoma and mucoepidermoid carcinoma arising centrally within the jaws are often associated with other types of dental cycts. Review of 36 instances of central epidermoid carcinoma has disclosed that 75% were associated with a cyst lining; the 2-year survival rate was found to be 53%. Central mucoepidermoid carcinoma was associated with a dental cyst or impacted tooth in 48% of the cases, and enjoyed a 100% 2-year and 5-year survival; however, 2 patients were recorded alive with disease at 4 months and 10 years, whereas another patient succumbed to disease 14 years postoperatively.

Symptomatic osteoarthritis of the temporomandibular joint: report of a case.

A case of osteoarthritis in the TMJ which manifested clinical symptoms, radiographic changes, and the classic microscopic alterations has been presented. Whether the condition was a primary or secondary form of the disease could not be unequivocally ascertained, as the symptoms preceded the injection of a sclerosing solution and a mandibular fracture, both of which could be significant contributing factors to a trauma-induced secondary osteoarthritic change. Nevertherless, a lack of symptoms in other joints would tend to exclude a generalized (primary) form of osteoarthropathy. In this regard, symptoms referable to the TMJ (to the exclusion of other joints) are more consistent with findings of secondary osteoarthritic change. Whether osteoarthritic changes were discernible by radiography in the TMJ before the traumatic episodes recorded in the history is unknown. Indeed, a developmental anatomic anomaly could not be ruled out. Regardless of whether the changes were the result of primary degenerative disease or chronic trauma, the symptoms were adequately resolved by surgical intervention.

The effects of cosmic particle radiation on pocket mice aboard Apollo XVII: appendix II. Evaluation of oral, dental, and skeletal tissues.

A sparse neutrophilic leukocytic infiltrate was found in the gingival sulcus, both in the flight and the control animals, while no changes were observed in the palate. Mitoses in gingival and palatal tissues were in approximately equal numbers in all animal groups. The tongues of flight mice and controls contained areas characterized by vascular dilatation, separation of muscle bundles, and regressive and degenerative changes in muscle fibers. Mucous glands in the posterior part of the tongue of flight and control animals exhibited acinar distension. Also examined were the vertebral column; femur, knee joint, tibia and fibula of the right hindlimb; and the tracheal cartilages. No evidence of cosmic ray particle effects was found in any of these tissues.
