Evaluation of three pulpotomy medicaments in primary teeth.

AIM: To examine the success of the one-appointment pulpotomy technique with three different medicaments on primary molar teeth. METHODS: The study was conducted on 104 primary molars in 104 children with an indication for pulpotomy treatment on at least one primary molar. Primary teeth were treated with either formocresol (FC) (34 teeth), calcium hydroxide (CA) (33 teeth) or ferric sulphate (FS) (37 teeth) using standardised criteria for the pulpotomy procedures. Teeth were clinically and radiographically evaluated during the examination period of 18 months. RESULTS: The clinical success rate at 18 months for the FC and FS groups was 90.9% and 89.2%, respectively. The CA showed an overall clinical success rate of 82.3%, with no statistical difference compared with either the FC or FS groups. The overall radiographic success for each technique was: FC 84.8%, CA 76.5%, and FS 81.1%. The presence of a dentine bridge above the pulp amputation site was observed radiographically for CA (47%), and FS (40.5%) pulpotomies without any statistical difference. Radiographic examination did not reveal the presence of a dentine bridge for any of the teeth treated with FC pulpotomy. CONCLUSION: Favourable clinical and radiographic success rates of ferric sulphate pulpotomy, comparable to formocresol were obtained. Therefore, ferric sulphate can be recommended as a pulpotomy medicament.

Analysis of pH variation of various calcium hydroxide compounds in vitro.

Among the reasons for the use of calcium hydroxide products, there is their alkalinity. Variations in the alkalinity of six commonly used calcium hydroxide compounds were studied in vitro at different time intervals. All these compounds rendered the saline solution strongly alkaline. Dycal, Life, Nucap and Reocap, had a weaker effect as compared with Contrasil and to Pulpdent paste. Such differences in the pH values were accompanied by differences in calcium loss, as revealed by scanning electron microscopy. Differences in the alkaline pH values and calcium losses among these calcium hydroxide compounds may account for their different clinical effectiveness in vivo.

[Micro-plasma treatment of dental pulp in animal experiments].

The direct and indirect effect on the endodont after thermic treatment with the micro-plasma unit from EGIDE were examined in animal experiments. The EGIDE unit is considered by its producer to be an alternative for CO2 lasers. The histological evaluation showed that both the plasma-therapy of dentin and the exposed pulp lead to massive pathological changes of endodont and was inferior to traditional methods as the indirect pulpcapping.

[A model of an in vitro biological assay controlled by immunofluorescence and scanning electron microscopy].

This study was designed to complete the cell culture test for the cytotoxicity assessment of dental material presented by Christen et al. (1989) and Regad et al. (1989). Two liner materials were selected for this experiment which had already been subjected to both in vivo and in vitro tests. After 2, 7 and 14 days of contact with the test materials, the cell responses were evaluated under the light microscope by their growth pattern and morphological aspects. Cell synthesis of fibronectin and type I and III collagen was studied by immunofluorescence. Surface appearance of the cells in contact with the materials as well as their structures were observed by scanning electron microscopy. This study confirmed the viability of the in vitro cytotoxicity assessment methods with cell cultures. The results also demonstrated the potentials of this method in the early screening of dental materials for their biological compatibility.

Twenty-four-month clinical trial of visible-light-activated cavity liner in young permanent teeth.

A clinical study of young permanent teeth for twenty-four months evaluated the use of a new product, VLC-Dycal, as a cavity liner. VLC-Dycal is a light-activated calcium hydroxide cavity liner. After twenty-four months, VLC-Dycal had a 91 percent success rate used as a liner with young permanent teeth. From the fifty-four teeth evaluated at twenty-four months, only five were failures. Failure occurred more frequently with DPC. Of the five teeth that became devital over the twenty-four months, three were DPC. The success rate for DPC was 70 percent. IPC had a success rate of 85 percent. None of the CCR procedures failed in the study. Because of the improved physical properties, VLC-Dycal was evaluated in a clinical trial for biological properties and proved to be a useful cavity liner for young permanent teeth.

[Penetration of calcium hydroxide based cements by dental enamel conditioning acids].

It was verified the penetration of phosphoric acid into 3 commercial calcium hydroxide-based cements (Life, Renew and Prisma VLC Dycal). The colorimetric method employed permitted the identidication of phosphorus amount in representative samples of 6 successive layers 0.1 mm thick of each material. The acid etching used were the commercial products Scotchbond Etching Gel--3M at 36.114% by weight and Solução Condicionadora--Johnson & Johnson at 36.054% by weight. The contact time was 60 seconds. The result showed that layers 0.1 mm tick for Life and Prisma VLC Dycal and 0.2 mm thick for Renew were able to block the penetration of phosphoric acid solution whereas layers 0.1 mm thick for the 3 cements were able to block the penetration of phosphoric acid gel.
