Treatment of prepubertal periodontitis. A case report and discussion.

This paper reports the treatment of prepubertal periodontitis in a 3-year-old girl with Papillon-Lefèvre Syndrome. Initially, the patient was found to have a myeloperoxidase deficiency and microbiological tests have identified Bacteroides and Fusobacterium, in 60% and 25%, respectively of the total number of microbial flora cultivated. The initial treatment was extraction of all the primary teeth with grade 3 mobility, scaling, root planing and daily subgingival irrigation with a 0.2% solution of chlorhexidine. Several months before the eruption of the first permanent molars, the rest of the primary teeth were extracted. The patient was treated with daily subgingival irrigation of chlorhexidine and weekly professional oral hygiene. At the age 6 1/2 years, the permanent teeth have normal gingiva and crevice depths; microbiological investigation reveals a prevalence of the coccoid forms, and radiographs show no evidence of periodontal pathology.

Neutrophil dysfunction in prepubertal periodontitis associated with Papillon-Lefèvre syndrome.

Although prepubertal periodontitis (PP) is often associated with the Papillon-Lefèvre (PLS), the etiopathogenetic mechanism in this disease has not been clarified as yet. A three and half year old female with leukocyte chemotaxis deficiency and decrease of T-lymphocytes is presented. The immunohistochemical evaluation of neutrophils showed a reduction of myeloperoxidase content, whereas ultrastructural studies revealed no particular change. The possible role of such a deficiency in the pathogenesis of the periodontal lesion is discussed.

[Motivation for seeking periodontal care in a Palermo population].

The Authors find a disagreement between symptomatology referred by patients and clinical pictures of pathology observed by sanitary operators. For instance a large percentage of patients considers bleending less important than the presence of calcolus. It is necessary a better information and secondary prevention increased.

[Epulides: the histopathological and epidemiological aspects].

The authors examined 195 epulides in order to point out distribution of this pathology in relation to some clinical, epidemiological and histopathological parameters. The Authors have found that the epulis is more prevalent in the female sex and in the anterior sextants. The epulides were subdivided on the basis of histopathological findings into: pyogenic granuloma (GP), giant cell granuloma (GGC), fibrous hyperplasia (IF), peripheral fibroma with calcification (FPC) and variety lympho-plasma-cellular (LP). Furthermore investigating the correlation between sex and histopathological variety it was found a significant prevalence of the GGC in the male sex, whereas the correlations within the age's sets are the followings: the LP is more prevalent in the IV age set (46-60 years), whereas the GP is more prevalent in the III age set (31-45 years) and in the V age set (greater than 60 years). This finding revaluates the hormone's influence in the vascular proliferation of the GP. IF and FPC are, in percentage, less frequent than others histopathological variety regarding to the size, it was found that GGC is the bigger than the other types, whereas IF is the smaller.

[Crevicular fluid: active site marker].

The qualitative studies of gingival crevicular fluid can be used for a reliable diagnosis of the beginning of active periodontal disease. Some changes in the crevicular fluid components are correlated with rising inflammation both in gingivitis and in periodontitis; the degradation products of the connective tissue as hydroxyproline, and inflammation mediators, as prosaglandine, can be find in it. The concentration of these components in crevicular fluid can be used as a reliable marker to individuate precociously the rising of an active site where an early treatment of periodontal disease can be effected.

[Diet analysis and correlation of food cariogenicity and DMF].

The authors evaluate the distribution of the intake of some fundamental foods in diet of 6-11 years-old school children group. The authors evaluate proteinic, lipidic and glycidic components of diet and total calories. Besides the authors calculate the alimentary cariogenicity in relation to DMFT/dmft.

[Radiographic examination in periodontology: evolution and prospectives].

Dental radiography has long been considered useful in the diagnosis of periodontal disease, it was employed in epidemiological studies in longitudinal studies, in the morphological and volumetrical evaluation of bone lesions and in the diagnosis and prognosis of periodontitis. However the radiographic technique and its interpretation were not always accurate. We can divide the evolution of the radiographic interpretation of periodontitis in three periods: the first period is comprised from the early years of the periodontal science to the seventies; in this period in spite of the evolution of the radiographic technique, there wasn't a standardization of the diagnostic criteria because of the un-understanding of the etiopatogenesis of periodontitis. In the second period, that is comprised from the seventies to the present, the understanding of the etiopatogenesis and of the evolution of periodontal breakdown, made possible the standardization of trials and diagnostic criteria and the fixation of limitations and indications of the radiographic interpretation of periodontitis. The third period, that is a prospect for the future as clinical application, at the present has application only in research. In this period use of new techniques, as scintigraphy and computerized analysis of radiographic image, made possible an higher sensibility of the radiographic technique.

[Physiopathology of alveolar bone].

Bone tissue is a dynamic system in which the net balance between resorption and apposition defines the final osseous form. This process occurs in minute asynchronous foci and results from a cascade of activations, cooperations and inhibitions of specialized cells (osteoblasts and osteoclasts). The alveolar bone resorption due to periodontal disease is a complex and dynamic chain reaction in which both osteoclasts and osteoblasts have a role in the hormonal interactions occurring during the course of the resorption activity. Both microbial and host factors as prostaglandins, endotoxins and lipoteic acid seems to be able in activating bone resorption. However bone resorption can be interchanged with repair formative episodes, more or less intense, which can delay the destructive process.

[Costs and dental operating levels in a group of Palermo children].

The authors, after evaluating the necessity of dental treatment in a school children sample, analyzed operative time and costs. the collected data show these therapeutic time and costs are very high. these therapeutic procedures will determinate a significative decrease of complexes therapeutic trails.

[Dietary habits and oral health indices in a group of public school children].

The authors explain some fundamental concepts regarding the effect of diet on chemical plaque composition and the influence of carbohydrates on some bacterial species. They besides report the results of their epidemiological research in order to emphasize the influence of the alimentary habits on some index of oral health.
