Subjects received verbal and tactile toothbrushing instruction and used their assigned methods twice daily. They were recalled at 1 and 6 months for clinical measurement and reinforce of instruction. Significance of PI and GI over time was compared
using the paired t-test and between brushing group at each time point using the t-test. Results. Over the 6-month period, there were significant reduction from baseline for the mean PI and GI in both groups (P < 0.001). There were no significant differences between two methods at each time point (P > 0.05), however. Conclusions. Both the horizontal Scrub and modified Bass methods can be effectively reduced plaque index and gingival learn more index http://www.selleckchem.com/products/ABT-263.html in visually impaired students. The efficacy of both methods was not different, however. “
“International Journal of Paediatric Dentistry 2010; 20: 336–340 Background. When diagnosing caries using clinical judgment only, the prevalence of approximal caries is highly underestimated. Yet, surveys on this topic predominantly included adolescents and young adults. Aim. To determine the additional diagnostic value of bitewing radiographs in 6-year-old children and to detect approximal dentin caries in the primary dentition. Design. A total of 50 children were assessed both clinically (dmfs, oral hygiene) and radiographically
by two experienced dentists. The relation between dmfs-scores and amount of plaque was established using Pearson’s correlation coefficients at a significance level of 0.05. Results. In nine patients (18%) it was impossible to make radiographs. Bitewing radiography appeared to have an additional effect of 97% when only caries in dentin is considered. The additional value for detecting inadequate restorations was 600%. Furthermore, the dmfs was highly correlated to the amount of plaque found. Conclusion. Although not possible
to achieve in all 6-year-old children, bitewing radiographs can reveal a considerable amount of carious surfaces and inadequate restorations, which appear clinically sound or adequate. “
“The aim of this OSBPL9 in vivo study was to evaluate the accuracy and reliability of electronic apex locater and radiographic determination of root canal length in primary teeth. A total of 32 human primary molar teeth (96 roots) were selected. After endodontic access preparation, root canals were irrigated with physiological saline solution. The access cavities were dried with cotton pellets and, the roots were dried with paper points before performing the electronic measurement. The root canal length measurements were first taken with an apex locater (EndoMaster), and then, a size ♯ 15 K-file was inserted into the root canal, and radiography was taken to determine the working length measurements. The measurement data were recorded and compared by one-way anova and Kruskal–Wallis tests. P < 0.05 was accepted for the significance.
