Objectives: The aim of this in-vitro study was to determine the antimicrobial capacity of a Berberis vulgaris plant extract on the bacteria being associated with caries including, Streptococcus mutans, S. sobrinus, S. sanguinis, S. salivaris and Lactobacillus rhamnosus.Material and methods: Chlorhexidine 2% (CHX) mouthwash and ampicillin (10 μg/ disk) were applied as positive control groups. Inhibition zone, minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) related to stem, leaf and fruit of B. vulgaris plant were recorded for every five bacteria. Data were analyzed using SPSS ver. 22, one-way ANOVA repeated measure and post hoc Tukey statistical test. The significance level was set at p < 0.05.Results: There were no significant differences between the antimicrobial capacity of the positive controls and the extract from the stem and fruit of B. vulgaris (p > 0.05).The MIC values of the extract from the stem were significantly lower against S. sobrinus (64 μg/ml) and L. rhamnosus (128 μg/ml). The MIC value of the extract against S. mutans was significantly lower in the fruit group (64 μg/mL). The MBC value of the extract against S. sobrinus and L. rhamnosus was significantly lower in the stem group (128 μg/ml). The MBC value against S. mutans was significantly lower in the fruit group (128 μg/ml).
Conclusions:The results showed that CHX and B. vulgaris plant extract have similar antimicrobial activity against bacteria being associated with caries. Therefore, B. vulgaris, which shows antibacterial capacity, could be considered for further investigation as a safe, phytotherapeutic mouthwash to prevent dental caries.
Objective: Diagnostic casts are one of the standard components of orthodontic records. But they have several drawbacks such as the need for physical space for storage and the risk of breaking due to their brittle composition. Today, the digitalization of orthodontic models is a progress in orthodontics. The purpose of this study was to compare and evaluate common orthodontic linear measurements on plaster casts and digital 3D models using Maestro 3D ortho studio ® scanner and software (AGE Solutions ® , Pontedera, Italy).Materials and Methods: Study casts of 30 orthodontic patients were selected. Tooth width, space analysis, Bolton analysis, overjet, overbite, and linear measurements of dental arch dimensions were performed by two examiners on plaster casts and digital models.Statistical Analysis: Intra-and interexaminer agreements were evaluated in both manual and digital methods and paired t test was used for evaluating the agreement between the manual and digital measurement. The significance level was set at 0.05.
Results:The intraexaminer agreement was excellent (ICC > 0.75) for most variables in both manual and digital methods. The correlation between the two examiners was significant (p < .05) for most manual and digital measurements. The differences between the manual and digital measurements, although maybe statistically significant, were not clinically significant for most variables.
Conclusion:The use of "Maestro 3D" (AGE Solutions, Pontedera, Italy) scanner and software was acceptable for orthodontic diagnostic measurements instead of study casts.
