Temporary and permanent restorations for fractured permanent teeth with immature apices: a clinical study.

Clinical and radiological studies of the fractured teeth of patients between seven and eleven years old were conducted to assess the use of permanent and immediate (emergency) techniques for reconstructing anterior permanent teeth with immature apices. The general hypothesis states that, given the physical and biocompatible properties of the materials used in the immediate (emergency) technique, there are no significant differences between the two techniques as far as pulp vitality and apical growth are concerned. A sample of fifty-six patients was selected. They had Class I, II or III fractures, for which permanent and immediate (emergency) techniques were used in equal numbers. Thermal, mechanical, and electrical tests were used to evaluate pulp vitality compared with the homologous tooth. Apical convergence was the radiological criterion used for determining the end of the radicular process. After one year, both techniques allow preservation of pulp vitality. Results show that, unlike the conventional technique (permanent), radicular formation was completed first in teeth reconstructed using the immediate (emergency) technique. Statistical analysis shows no definitive relationship between the technique used and completion of apical growth time (P > 0.05). In conclusion, comparison between the mediate (permanent) and immediate (emergency) techniques shows that the immediate (emergency) technique is an adequate alternative for reconstructing fractured teeth, because of the greater esthetic and functional advantages at the patient's disposal.

Biocompatibility of primer, adhesive and resin composite systems on non-exposed and exposed pulps of non-human primate teeth.

PURPOSE: To evaluate the histologic response of 332 non-exposed and 127 exposed monkey pulps applying nine adhesive systems. MATERIALS AND METHODS: Class V and Class I cavities were used in non-exposed and exposed monkey pulps at the three ISO usage time intervals. RESULTS: There were no histologic differences in pulp responses among the nine adhesive systems used in either Class V and/or Class I cavities when compared to pulp responses of Ca(OH)2 controls at the ISO time intervals. The nine adhesive systems and resin composites are non-toxic to either non-exposed or exposed pulps, being biologically compatible to pulp tissues when placed on mechanical pulp exposures following hemorrhage control with a 2.5% NaOCl and per manufacturers' directions. It is imperative that clinicians understand the biological importance of hemorrhage control as well as the technique sensitivity of hydrophilic primers in order to optimize the efficacy of adhesives for clinical success against microleakage of bacterial factors.

Management of the deep carious lesion and the vital pulp dentine complex.

This article describes the relationship between the carious process and pulp-dentine complex reactions. Where the balance between the two is in favour of the carious process and where conventional cavity preparation leads to a direct pulp exposure, the direct pulp cap technique is described. The success of the technique is addressed and more importantly an alternative technique for caries removal, namely stepwise excavation, is described which may lead to a reduced risk of carious exposure and the need for the direct pulp cap technique.

Biological response of pulps submitted to different capping materials.

Pulp capping is a procedure that comprises adequate protection of the pulp tissue exposed to the oral environment, aiming at the preservation of its vitality and functions. This study evaluated the response of the dental pulps of dog teeth to capping with mineral trioxide aggregate (MTA) or calcium hydroxide P.A. For that purpose, 37 teeth were divided into two groups, according to the capping material employed. Two dogs were anesthetized and, after placement of a rubber dam, their pulps were exposed in a standardized manner and protected with the experimental capping materials. The cavities were then sealed with resin-modified glass ionomer cement and restored with composite resin. After sixty days, the animals were killed and the specimens were processed in order to be analyzed with optic microscopy. It was observed that MTA presented a higher success rate compared to calcium hydroxide, presenting a lower occurrence of infection and pulp necrosis.
