Relationship of Lower Lingual Arch Appliance Use and Impaction of Second Molars: A Retrospective Study.

The purpose of this study was to determine the prevalence of permanent mandibular second molar impaction in pediatric patients treated with a lower lingual holding arch (LLHA) to maintain lower arch perimeter. In this retrospective study, 259 radiographs of nine- to 17-year-old pediatric patients were examined for permanent mandibular second molar impaction. A total of 127 patients with LLHA were compared to a control group of 132 patients who had not received LLHA.

Bottle-Weaning Recommendations Among Pediatricians and Pediatric Dentists.

The purpose of this study was to determine how pediatricians (MDs) and pediatric dentists (PDs) interpret professional associations' guidelines for weaning of bottle-fed infants and assess ensuing provider recommendations. A survey was sent to 11,479 MDs and PDs. 721 MDs and 1,005 PDs responded, yielding an overall response of 1,726 (15 percent).

Inferior alveolar nerve block and third-molar agenesis: a retrospective clinical study.

Background: Children often receive inferior alveolar nerve blocks (IANBs) when their third molars are just beginning to develop. The location of the third-molar follicle is close to where the needle penetrates during an IANB. The authors examined the possible association between IANBs and missing third molars.

Shear bond strength of seventh generation bonding agents on dentin of primary teeth--an in vitro study.

This controlled, randomized, in vitro study evaluated the shear bond strength of several seventh generation bonding agents on the dentin of primary teeth. Six different adhesives were used: Xeno IV, Clearfil S3 Bond, Adper Prompt-L-Pop, AdheSE One, Bond Force, and Optibond (control). Ninety primary teeth were prepared by wet grinding with a 320-grit silicon carbide paper on a polishing wheel running at 110 RPM.

Marginal microleakage of triage sealant under different moisture contamination.

Purpose: Glass ionomer sealants (GISs) are promoted in pediatric dentistry for their moisture-friendly properties. This study's purpose was to investigate the marginal leakage of a glass ionomer sealant (Fuji Triage) under different moisture environments.

Methods: Eighty extracted teeth were distributed into 4 groups: (1) control; (2) saliva contamination with 1-second air-thinning; (3) saliva contamination with 10 seconds of air-drying; and (4) saliva contamination with reconditioning.
