In a study on the influence of different irrigant solutions—sodium hypochlorite (control), chlorhexidine (CHX), and grape seed extract (GSE)—applied before cementation, GSE and CHX improved the bond strength of glass fiber posts to root dentin.

The maxillary sinuses of 500 subjects were analyzed by cone beam computed tomography to determine the prevalence of pathologic alterations. The most prevalent finding was mucosal thickening, followed by mucous retention pseudocyst, partial opacification, and total opacification. These anomalies may necessitate a modification in a treatment plan.

Different microwave radiation regimens (3, 5, or 7 minutes’ exposure) were applied for disinfection of type IV dental stone surfaces, and the influence of these regimens on surface roughness and dimensional change was assessed. Exposure times of 5 and 7 minutes sterilized specimens exposed to Staphylococcus aureus, Escherichia coli, or Candida albicans. A 3-minute regimen successfully eradicated E coli and C albicans, but S aureus colonies were observed in 50% of Petri dishes. None of the regimens caused a significant difference in dimensions or surface roughness.

The efficacy of casein phosphopeptide–amorphous calcium phosphate (CPP-ACP) was compared to that of the combined enzymes lysozyme, lactoferrin, and lactoperoxidase (LLL) in reducing Streptococcus mutans counts. There was no significant reduction in the numbers of S mutans after application of CPP-ACP, but a significant reduction of S mutans was observed after 3 applications of LLL.

A survey examined pediatric dentists’ perspectives on the types of dental services general dentists provide to children aged 0-3 years. Among the respondents, 58% agreed with general dentists’ providing an age 1 dental visit, but only 24% agreed with general dentists’ performing complex behavior management techniques, such as sedation, for very young patients.

The gingival line angle (GLA), proximal contact area (PCA), and other gingival parameters were measured to provide esthetic guidelines for clinicians. The mean GLAs of the left and right sides differed significantly, and the mean PCA decreased from mesial to distal sites bilaterally. There was a significant positive correlation between the GLA and the PCA.

The microleakage and shear bond strength of a self-etching Giomer-based sealant (placed with or without phosphoric acid etching) were compared with those of a traditional resin sealant placed after phosphoric acid etching. When used alone, the Giomer system had significantly greater microleakage and lower bond strength than the traditional sealant or the Giomer material placed after acid etching.
