Parental attitudes toward behavior management techniques used in pediatric dentistry.

Previous studies evaluating parents' attitudes toward behavior management techniques used in pediatric dentistry suggest that parental attitudes are generally negative. The purpose of this study was to reexamine this issue by comparing the effect of prior explanation on parental acceptance of eight behavior management techniques. Videotaped segments were made of children's dental appointments containing examples of eight behavior management techniques. One group of 40 parents viewed a videotape which provided no explanation for each technique before it was shown. Another group of 40 parents viewed a videotape which provided no explanation of the techniques. The parents then were asked to rate the acceptability of each technique using a visual analogue scale. Results indicated that the informed parents were significantly more accepting of behavior management techniques than the uninformed parents but both groups were generally positive about the techniques studied. Further, parents reporting greater stress were less accepting of the techniques studied.

Comparison of Kodak D-speed and E-speed x-ray film in detection of proximal caries.

Due to the differences in the findings of earlier studies, it was decided to investigate further and compare the two film types. This study compared the radiographic images of proximal caries lesions on D-speed radiographic film with those seen on an E-speed radiograph. No significant difference was found in the ability of dentists to diagnose.

Failure strength of four veneered primary stainless steel crowns.

The purpose of this study was to determine the amount of shear force required to fracture or dislodge the veneered facings of four commercially available veneered primary incisor stainless steel crowns (SSC) and to characterize the veneer failures. Forty Unitek SSCs (#4 left central incisor) were shaped to fit a master die and then 10 each were mailed to four commercial dental laboratories that produce veneered SSCs. The resulting four types of crowns tested were: Cheng Crowns (CC), [Peter Cheng Orthodontic Laboratory]; Kinder Krowns (KK) [Mayclin Dental Studio, Inc]; NuSmile Primary Crowns (NC), [Orthodontic Technologies, Inc]; and Whiter Biter Crown II (WB), [White Bite Inc]. Each crown was cemented onto a standardized die and then thermocycled at 4 degrees C and 55 degrees C for 500 1-min cycles. Each die was then placed into a custom holder on the Instron (Model 4204) testing machine. A force was applied at the incisal edge of the veneer at 148 degrees, (the primary inter-incisal angle), with a crosshead speed of 1 mm/min until the veneer fractured or was dislodged. The mean force (N) required +/- SD to produce failure was, respectively: KK (397.2 +/- 53.0); NC (447.2 +/- 78.5); CC (511.9 +/- 83.4); WB (686.5 +/- 181.4). Analysis of variance (ANOVA) indicated significance at P < 0.0001. A Scheffe's post hoc comparison demonstrated that the Whiter Biter (WB) group required significantly (alpha = 0.05) more force for failure than the other three groups.(ABSTRACT TRUNCATED AT 250 WORDS)

Managing a peripheral ossifying fibroma.

The Peripheral Ossifying Fibroma is an inflammatory lesion which most often appears in twenty-five to thirty-four-year-old females. It averages 1.0 cm at its greatest dimension. This case reports a seven-year-eight-month-old female who presented with a peripheral ossifying fibroma lesion which measured 2.7 cm by 1.5 cm by 1.0 cm. A review of peripheral ossifying fibroma, and the management and postsurgical sequelae of this child are discussed.
