Pulsed laser beam effects on gingiva.

The effects of CO2 lasers on human gingiva have been evaluated. Pulsed Nd:YAG lasers have only been available for clinical use in dentistry since 1990. This study evaluated the efficacy of a low-power pulsed laser in removing pocket lining epithelium in humans with moderate periodontitis. 24 specimens of gingival tissue, from 6 patients, were studied microscopically following the application of a pulsed Nd:YAG laser (1064 nm) contact probe with a spotsize of 320 mu. Power settings of 1.25 and 1.75 Watts and a frequency of 20 Hz were used. Treatment time varied from 2 to 3 min. The specimens were fixed and processed in the usual manner. Four representative sections for each tooth were examined with the light microscope at 25 and 100 x magnification. Most sections (83%) exhibited complete removal of epithelium except for traces of viable basal cell remnants at the coronal sulcular margin (17%). The underlying connective tissue demonstrated no evidence of necrosis or carbonization. Morphologic features showed minimal change other than removal of pocket lining epithelium, compared to control sites. The pulsed Nd-YAG laser can remove pocket lining epithelium in moderately deep pockets at 1.25-1.75 W of power.

Peripheral inflammatory root resorption. A review of the literature with case reports.

External resorptions associated with inflammation in marginal tissues are many times misdiagnosed and confused with caries and internal resorptions. A lack of uniformity in nomenclature has added to the confusion. This paper reviews the literature and presents cases to illustrate a rational approach to diagnosis and treatment. A new name is suggested to better reflect the features of this type of root resorption: peripheral inflammatory root resorption.

Root canal calcification associated with prednisone therapy: a case report.

This report details an 8-year follow-up of a patient with systemic lupus erythematosus (SLE) who was treated with up to 60 mg per day of prednisone for more than 8 years. Radiographic documentation demonstrated complete calcification of all pulp chambers and root canals during an 8-year period. During this time, the patient had been successfully treated for case type III adult onset periodontitis. Follow-up examinations recorded minimal attachment loss, and radiographs showed stable bone levels.

Periodontal repair of periapical lesions: the borderland between pulpal and periodontal disease.

A series of cases demonstrating the destruction of periapical periodontal structures, without pulpal involvement has been presented. Treatment using both surgery and antibiotics resulted in extensive healing without any concommitant endodontic therapy. The results suggest that lesions affecting the apical periodontium are either periodontal or pulpal in origin. Careful diagnosis allows the maintenance of pulp vitality in cases where apical destruction has a source other than an infected pulp. The commonly held belief that lateral and accessory canals are a significant source of pulpal contamination from deep periodontal pockets has been questioned.

Robert Neumann: a pioneer in periodontal flap surgery.

The contributions of Robert Neumann to the development of periodontal flap surgery are acknowledged. Neumann, born in 1882 was the leader of the Berlin group of dentists who advocated "the radical surgical treatment of pyorrhea". This approach was widely reported in European journals and sometimes referred to as the "Neumann operation". A biographical sketch and detailed descriptions of his operative procedures are included. Some of the historical background surrounding the priority question in the development of flap surgery is outlined.

Effects of scleral collagen upon the healing of experimental osseous wounds.

Standardized wounds were created in the femurs of 13 female white New Zealand rabbits and implanted with autogenous scleral connective tissue, Achilles bovine tendon collagen chips and cores of cancellous autogenous bone and marrow. A blood-filed wound served as a control. The dynamics of the healing of these wounds over periods of time ranging from 12 days to 3 months was studied by routine histology, fluorescent microscopy and by radiography. Rapid healing of the control and bone implant wounds occurred but was retarded by the implantation of sclera. Collagen chips provoked an active lymphocytic response and severely impeded the healing of the experimental wounds. These experiments were discussed in light of the current interest in allogenic scleral implants in periodontal therapy.
