The effects of oral conscious sedation on future behavior and anxiety in pediatric dental patients.
PURPOSE: This study investigated the relationship between oral conscious sedation and subsequent behavior in the dental setting. METHODS: The sample consisted of 38 children between the ages of 39 to 71 months (mean=50 months) who had been treated with oral sedation 2 to 34 months(mean=13 months) previously, and a control group of 38 children, matched by age (mean=51 months) and gender, who had received dental treatment without conscious sedation or general anesthesia one week to 3 years previously. Subjects were matched by age and gender. All children received a standard recall examination and a prophylaxis, during which behavior and anxiety were measured. Independent variables included age at the time of sedation, present age, gender, time elapsed since sedation, effectiveness of sedation, parental scores on Corah's Dental Anxiety Scale and parent's answers to a questionnaire. The dependent variables were child behavior (rated with the 4-point Frankl scale) and self-reported anxiety ratings. RESULTS: Both groups had mean behavior ratings of positive or very positive (experimental group mean=3.13; control group mean=3.34). There were no statistically significant differences between the groups and there was little correlation of independent and dependent variables. CONCLUSIONS: There is no relationship between oral conscious sedation and the future behavior of children in the dental setting.
Project USAP 2000--use of sedative agents by pediatric dentists: a 15-year follow-up survey.
PURPOSE: A national survey of members of the American Academy of Pediatric Dentistry was conducted to provide a 15-year update of information regarding the use of sedative agents by pediatric dentists. METHODS: All 3,315 active members of the Academy were sent questionnaires regarding the frequency of their use of sedation and 1,778 responded. Practitioners were questioned regarding their use of sedative agents and the nature of their patients receiving sedation. In addition, they were questioned in regard to their use of restraints and reasons for change in their use of sedation during the past two years. RESULTS: In regard to the use of nitrous oxide alone, 47% of practitioners responded that they use nitrous oxide less than 11% of the time. In regard to other types of sedative agents, most practitioners use little, if any, sedation. Eighty-two percent use sedation for less than 11% of their patients. Of the 1,778 respondents, 1,224 used drugs other than nitrous oxide. In a typical three-month period, they performed 77,112 sedations. Of that number, 61,662 (80%) were administered by only 478 practitioners who use sedation on the average of once or greater each day. CONCLUSIONS: In comparison with previous surveys in 1985, 1991 and 1995, these results demonstrate an overall increased use of sedation by pediatric dentists. However, the increased use is due primarily to an increase in the numbers of practitioners who are heavier users of sedation (once or greater each day).

Effect of primer solvent and curing mode on dentin shear bond strength and interface morphology.
UNLABELLED: There is a need to study the main and interactive bonding effects of differences in solvent and curing mode used for adhesive monomers in dentin bonding systems. OBJECTIVE: Two solvents (acetone and ethanol) and curing methods (light cure, dual cure) were evaluated on their effects on bond strength and interfacial morphology. METHOD AND MATERIALS: The adhesives studied were based on two monomers, pyromellitate of glyceryl dimethacrylate (PMGDM) and 2-hydroxy ethyl methacrylate (HEMA). Four groups of eight teeth each were cut to expose planar dentin sections and treated with (a) light-cure system with acetone as solvent (LCA group); (b) light-cure system with ethanol as solvent (LCE group); (c) dual-cure system with acetone as solvent (DCA group); and (d) dual-cure system with ethanol as solvent (DCE group). The treated sections were tested for shear bond strength to composite discs and interfacial morphology. RESULTS: The mean (standard deviation) of shear bond strength values (MPa) for the different groups were: LCA: 11.8 (2.3); LCE: 12.7 (2.7); DCA: 24.9 (9.3); and DCE: 21.6 (9.6). All bonded sections were characterized by a similar hybrid layer, resin tags, and overall interfacial morphology. CONCLUSION: There was a significant difference in shear bond strength as a function of cure mode, but not of solvent. The mean bond strength was higher for dual-cure systems studied. Oxygen inhibition effects may account for the difference between light-cure and dual-cure types.
