Permanent teeth pulpotomy survival analysis: retrospective follow-up.

Objectives: The aim of the present study is to evaluate risk factors influencing the success rates of pulpotomies both in young and adult populations.

Methods: Pulpotomies (n=273) performed by a single endodontic specialist were analyzed, and data on success rates were collected. Additionally, possible explanatory variables were noted such as: age, gender, clinical findings (teeth, type of restoration after pulpotomy), radiographic findings (dentin bridge formation) and systemic conditions.

Endodontics in primary molars using ultrasonic instrumentation.

Purpose: The purpose of this study, which is a series of consecutive case reports, was to describe and evaluate the protocol used in the treatment of pulpal necrosed of primary molars, used by the dental service of Social Support Foundation of the Moinhos de Vento Hospital, Porto Alegre, RS, Brazil.

Methods: Eighteen primary molars in 15 children, ranging from 4 to 10 years of age, were endodontically treated using ultrasonic instrumentation.

Results: Clinical and radiographic controls showed a success rate of 94%, considering an evaluation time of 14.

[The impact on costs and care of two approaches to reduce employees' dental plan expenses in a private company].

The present study evaluated the dental care plan offered to 4,000 employees of a private hospital and their respective families. The analysis covered three stages: (1) baseline (control), when dental care was provided by an outsourced company with a network of dentists paid for services, (2) a renegotiation of costs with the original dental care provider, and (3) provision of dental care by the hospital itself, through directly hired dentists on regular salaries. Monthly economic and clinical data were collected for this research.

Morphology evaluation of primary enamel exposed to antihistamine and fluoride dentifrice--an in vitro study.

This in vitro study sought to evaluate the action of a pediatric medication with low pH and high acidity in primary enamel submitted (or not) to daily applications of fluoride dentifrice. For this study, 70 blocks of primary molars (n = 10 per subgroup) were analyzed using scanning electron microscopy. Six subgroups (two control and four experimental) were submitted to different treatments for 10 days.

Orthodontic extrusion anchored in osseointegrated implants: a case report.

Rapid orthodontic extrusion is indicated for cases involving biological space invasion of the periodontal ligament in which the surgical increase of the clinical crown can compromise esthetics or the support of the adjacent teeth. This article presents the case report of a tooth with radicular perforation 1.0 mm below the bone crest.

Clinical comparative study of the effects of two types of mandibular space-regaining devices.

This study evaluated the results obtained by two space-regaining devices in children with mixed dentition and premature loss of mandibular deciduous molars. There were no statistical differences between the amount of space regained by each device; however, the distalizing screw regained space at a faster rate.

[Polarization of dental caries in a city without fluoridated water].

Increased overall exposure of the Brazilian population to fluoridated water and fluoridated dentifrices has been identified as the main factor in the reduction of caries prevalence. Thus, the objective of the present study was to evaluate the distribution of caries in a group of 437 children ranging from 6 to 12 years of age, residing in a city without a water supply fluoridation system and without a preventive dentistry program, with the aim of orienting future health measures towards improved cost-effectiveness. Clinical examination was performed on all the children, focusing on the indices defs (decayed, extracted, and filled primary dentition surfaces) and DMFS (decayed, missing, and filled permanent dentition surfaces), representing the number of dental surfaces that were either decayed, missing or with extraction indicated, or restored.

[Different forms of payment systems for dental services and their impact on care].

The Brazilian dental care sector is facing a paradoxical crisis characterized by a surplus of dentists and a large contingent of people lacking dental care, thus highlighting the need to improve management strategies. One necessary step is to analyze the various payment schemes for dental services. This paper reviews two important approaches, fee for service and capitation, and considers the impacts and consequences of payment strategies on the dental care system.

Effect of home bleaching and smoking on marginal gingival epithelium proliferation: a histologic study in women.

Background: Animal studies have suggested that home bleaching agents can cause morphological alterations and changes in the proliferative rate of oral epithelium.

Methods: A bleaching agent containing 10% carbamide peroxide with carbopol was used in 11 women (five smokers and six non-smokers) during a 5-week period. Two biopsies were performed, one of them 15 days before the beginning of the home bleaching treatment and the other immediately after the 5-week bleaching treatment.
