ABSTRACT
Aim: In this study, we assessed the use of advanced pharmacological behavior management techniques (BMTs) among pediatric dentists in Saudi Arabia and the barriers to their clinical application. Materials and Methods: This cross-sectional study used a self-administered electronic survey that targeted members of the Saudi Society of Pediatric Dentistry. The questionnaire included questions on five techniques of advanced and pharmacological behavior management recommended by the American Academy of Pediatric Dentistry. Descriptive statistics, frequency, Chi-square test, and Fisher's exact test were used to present the outcomes and independent variables. Results: A total of 57 pediatric dentists completed the survey. Nitrous oxide (N2O) sedation, general anesthesia (GA), and protective stabilization were used regularly by pediatric dentists in 70.2%, 68.4%, and 56.1% of the participants, respectively. A few participants reported using oral (14.0%) or intravenous (IV) sedation (10.5%) regularly. The most common barriers to using these techniques were either dentists' discomfort or the non-availability of the equipment/drugs. Conclusions: The most common method used by pediatric dentists was N2O inhalation sedation, followed by GA and protective stabilization. The participants' use of pharmacological BMTs, including IV and oral sedation, was relatively low.
ABSTRACT
Despite improvements in dental adhesive materials, internal adaptation remains a challenge in bonded restorations. The aim of this study was to compare microgaps and internal floor adaptation between two different self-etch adhesives in class-V cavities using cross-polarization optical coherence tomography (CP-OCT). In this in vitro study, standardized round class-V cavities were prepared in 20 non-carious human upper central incisor teeth. They were randomly divided into two groups, TN and SE, with each group receiving a different dental adhesive. In TN group, the adhesive used was all-in-one Tetric N-Bond Self-Etch (TN; Ivoclar/Vivadent, Liechtenstein), while SE group was bonded with two-step self-etch Clearfil SE Bond 2 adhesive (SE; Kuraray Noritake Dental Inc, Japan). The prepared cavities were restored with flowable composite and then stored in distilled water for 24 h. Next, they were immersed in silver nitrate, followed by immersion in a photo-developing solution. Optical comparison was carried out by CP-OCT to assess microgaps and composite adaptation at the cavity floor. A Mann-Whitney test was applied to the data, which showed a statistically significant difference in composite adaptation among the two groups (p < 0.001) with the SE group showing superior adaptation. CP-OCT is a reliable tool for non-invasive imaging that gives an insight into composite performance. Better adaptation was found with the two-step self-adhesive for the composite used in this study.
