[The comparative evaluation of the efficacy of surgical and nonsurgical periodontal therapy in relation to the oral hygiene conditions and the severity of the lesions].

A retrospective longitudinal study was carried out to evaluate the efficacy of surgical and nonsurgical periodontal therapy in reducing pocket depth values. This evaluation was made in relation to the strictness with which patients observed professional and domestic oral hygiene and in relation to pretreatment pocket depth values. Results showed that the two forms of periodontal therapy offer comparable results in terms of pockets reduction of either restricted or considerable depth, whereas the most important element in order to achieve therapeutic success was the observation of an effective professional and domestic plaque control.

General considerations in the treatment of periodontal disease: infection control, medications, and wound healing.

Although it is difficult to accurately predict the results of periodontal therapy, it may be possible to improve the success of therapy if the patient is considered from an immunologic, microbiologic, social, and behavioral point of view, as a heterogenous entity. The success or failure of a particular treatment can be related to the host's personal response to a therapeutic procedure rather than to the technique used.

[A longitudinal clinical study of the efficacy of tetracyclines combined with root planing in patients with periodontal disease].

A retrospective longitudinal study was performed to assess the effectiveness of tetracycline therapy associated with root planing compared with root planing alone in patients affected by medium to severe periodontal disease. From an analysis of results it appeared that the combined therapy was generally more successful, even though statistical significance was only achieved in cases of healing angular bone lesions. In conclusion, larger studies should be carried out to contribute to broaden the spectrum of indications for the use of antibiotic therapy in periodontal disease in adults.

[Modifications in the clinical and microbiological parameters of the periodontal tissues after the removal of overhanging class-II amalgam fillings].

A short-term longitudinal study was carried out to assess how microbiological and clinical characteristics, measured surrounding periodontal sites with amalgam class II fillings intentionally made to overhang, vary following their replacement with a correct form of filling. The results of the study showed a significant reduction of the total bacterial count and the percentages of Gram-negative and anaerobic organisms spreading from overhanging fillings to non-overhanging fillings. The paper concludes that, as has been already demonstrated in the case of onlays, there are both qualitative and quantitative variations in the subgingival plaque in the presence of overhanging fillings which can lead to periodontal damage.

[Ultrastructural morphological study of supragingival tartar].

Specimens of old supragingival calculus, collected from 5 patients with periodontitis, were examined electron-microscopically. Both intracellular and extracellular calcification were found. Intracellular calcification began as needle-shaped crystals or minute amorphous deposits within microorganisms. Extracellular calcification originated within the interbacterial matrix.

Rapidly progressive periodontitis. Neutrophil chemotaxis inhibitory factors associated with the presence of Bacteroides gingivalis in crevicular fluid.

In the last few years several bacteriological and immunological studies have investigated the role of bacteria and immune defects in order to establish the etiopathogenesis of periodontal disease. With regard to the immune system, a defect in polymorphonuclear neutrophil (PMN) chemotaxis has been frequently reported in patients with rapidly progressive or juvenile periodontitis. The purpose of this study was to investigate in five patients with rapidly progressive periodontitis and normal chemotaxis of peripheral blood PMNs the presence of chemotaxis inhibitory activity in gingival fluid and to relate such activity to three types of bacteria, often involved in rapidly evolving periodontal lesions, that are able to inhibit in vitro PMN chemotaxis: Bacteroides gingivalis, Capnocytophaga sp., and Actinobacillus actinomycetemcomitans. We found strong inhibitory activity in three of these patients. This activity was consistently associated with the finding of B. gingivalis in gingival pockets. We cannot rule out, however, that other substances not of bacterial origin could be responsible for such inhibitory activity. The strict association with B. gingivalis, known to secrete blocking factors, is highly suggestive, although this data must be considered preliminary.
