Objective: A retrospective study of the success rate of direct pulp capping (DPC) and indirect pulp capping (IPC) was carried out in children between 6-14 years-old, considering separately primary caries or caries affecting teeth with molar incisor hypomineralization (MIH).Material and methods: Data were collected in a dental public health service. Following the inclusion criteria, 232 treatments were analyzed. Success was defined by the presence of a functional tooth without clinical signs or symptoms of pulpal or periapical disease. The success rate was correlated to patient gender, the affected tooth and the indication of therapy using the chi-squared and Fisher exact test. The success time related to treatment type was evaluated through the Mann-Whitney test.Results: The IPC and DPC success rate was 99.4%, and 84.6%, respectively (p = .01).Success was significantly lower when caries affected teeth with MIH than when caries affected teeth without MIH (p = .01). The mean survival for DPC and IPC was 14.07 ± 1.30 and 15.98 ± 0.80 months, respectively (p = .07).Conclusions: When caries were located in teeth that were not affected by MIH, IPC was significantly more successful than DPC, but did not differ significantly when caries were placed in teeth with MIH.
Pinworm infection was prospectively studied during one year in 469 children attending three day care centers. Each child was examined at six months intervals using up to three perianal swabs with adhesive tape. Those found infected were treated with mebendazole. At the beginning of the study we found a prevalence of 28% that dropped to 13% and 12% in the following study periods. The reinfection rate was twice the incidence rate in both study periods. We also found a small percentage (10%) of the children reinfected in most or all study periods. There was a high correlation between reinfection and perianal itching. Our results add further knowledge to the epidemiology of intestinal parasites in day care centers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
