Marginal microleakage of intact occlusal calculus of primary molars extracted from a patient with a gastric feeding tube was compared with microleakage of pit and fissure sealants in calculus-free molars from a prior study. Observations indicated that calculus may serve as a “natural” occlusal surface sealant, rendering its removal from occlusal surfaces unnecessary in some patients.

Conservative stepwise excavation was used to successfully treat a mature permanent tooth that exhibited deep caries and apical periodontitis. At the 4-year follow-up, the tooth remained functional, presenting normal color and satisfactory restoration.

This study assessed the biocompatibility of a resin-modified glass ionomer cement when used as a liner in very deep cavities. While Vitremer caused persistent pulpal damage, 2 liner cements, Vitrebond and Dycal, were found to be biocompatible.

When a 9-year-old patient suffered external root resorption after avulsion and reimplantation of the permanent maxillary left lateral incisor, the root canal was obturated with gutta percha and mineral trioxide aggregate. The 3-year recall examination revealed no mobility, soft tissue alterations, or progression of resorption.

This study compared the shear bond strengths of 4 retentive materials for chairside pickup of implant attachments. A secondary goal was to compare the shear bond strengths of a retentive material and a traditional polymethyl methacrylate resin to metal housings.

This study assessed the impact of the width of keratinized mucosa (WKM) on periodontal parameters, including modified bleeding index, modified plaque index, modified gingival index, and gingival recession, and found that an association does exist between the WKM and peri-implant soft tissue health. A minimum of 2 mm of keratinized mucosa is recommended.

A study evaluating the influence of material opacity and preheating on a composite resin demonstrated that preheating at 60°C reduced both the sorption and solubility of the composite, but the opacity only affected the results for a specific shade of the material.

Antibiotic prophylaxis guidelines for the asplenic dental patient have changed over the last 30 years. While antibiotic prophylaxis is not routinely indicated prior to dental procedures for asplenic adult dental patients without risk factors, it should be considered for young children, immunocompromised patients with underlying disease, or any patient during the first 3 years after a splenectomy.

To assess the effects of different surface treatments on adhesion of Candida albicans to porcelain, porcelain discs received no surface treatment or were glazed, overglazed, or polished. Adhesion of C albicans was lowest in the overglazed group, and polishing provided a surface as smooth as a glazed surface.

A study in medically compromised patients with gingival inflammation demonstrated that toothbrushing alone, with water but without toothpaste, improved the health of gingival tissues and reduced the biofilm. The addition of an antibiotic solution to the toothbrush increased healing and further reduced bacteria.

An in vitro study found that contamination of both sound and caries-affected dentin with hemostatic agents decreased composite resin bond strength, although ViscoStat Clear had a less detrimental effect than either ViscoStat or trichloroacetic acid.
