Histological investigation of physiologically resorbing primary teeth using Ag-NOR staining method

PubMed ID: 12028313Objective. The aim of this study was to investigate pulpal tissue of primary teeth in early and late stages of physiological resorption by means of silver-binding nucleolar organizer region (Ag-NOR) staining. Study design. Ten primary teeth in early, ten in the late stage of resorption and five sound premolar teeth pulps as the control group were investigated by means of silver-binding nucleolar organizer region (Ag-NOR) staining. Results. The mean number of Ag-NOR's per nucleus increased with the continuing of the resorption process. The difference in the mean number of Ag-NORs was statistically significant both in the early and late stage of resorption compared with controls (P > 0.001). In the early stage of resorption calcific plates in the apical part of the pulps were observed. Odontoclasts, as well as inflammatory cells, were observed in the late stages of resorption. Conclusions. The increase in the mean number of Ag-NORs per nucleus with the progression of the resorption process in primary teeth suggests that metabolic cell activity in the early stages of resorption is enhanced and increased with the continuing of the process, thus showing the importance of the pulp tissue in the resorption process

Fluoride uptake by enamel in vitro following application of various topical fluoride preparations.

PubMed ID: 8217887Two conventional topical fluoride preparations; APF and neutral 2% NaF gel and two fluoride varnishes; Duraphat and Fluor Protector, were applied to 60 permanent and 20 primary teeth. The teeth were halved to provide test and control groups, and the fluoride uptake was measured using a micro acid etch technique, after 30 seconds and 60 seconds etching periods. All topical fluoride preparations in our study caused some fluoride uptake in permanent and primary tooth enamel compared to the control groups. Duraphat and APF were found to be more effective than the other agents

Peripheral giant cell granuloma: Three case reports

PubMed ID: 11314150Three cases of peripheral giant cell granuloma (PGCG) with histopathological and long-term evaluations are presented. In all the cases that were all female and ages ranged between 5.5 to-12 years, after complete surgical excision of the lesion no recurrence was detected during a follow-up period of 2 to 4 years. Although etiological factors could not be determined exactly, low socioeconomic status of the patients and unfavorable oral hygiene seemed to be the predisposing factors

Dental caries prevalence, dietary habits, tooth-brushing, and mother's education in 500 urban Turkish children.

PubMed ID: 9569784500 children with ages ranging between 2 and 13 years and their families joined the study. A detailed questionnaire and a 3-day food intake diary were evaluated to find the relationship between dental caries and dietary habits. It is concluded that the prevalence of caries increases by frequent and high sugar consumption. With lower age and lower caries experience followed a more balanced diet. There was an inverse relationship between caries prevalence and the mothers' educational level. The percentage of children who never or irregularly brushed their teeth was highest in the caries active group
