Clinical and Biochemical Efficacies of Green and White Tea Extract Mouthwashes in the Management of Plaque-Induced Gingivitis.
In this clinical study, chlorhexidine gluconate (CHX) was chosen as the positive control group, and the clinical and biochemical efficacy of mouthwashes with green tea, white tea and essential oil (EO) as the active ingredients were aimed to be examined comprehensively. A total of 112 participants with gingivitis were randomly assigned to four different groups and different mouthwashes were used for 4 weeks: CHX-MW group (as a positive control group), EO-MW group, GT-MW group and WT-MW group. The effects of the mouthwashes on plaque, inflammation and dental staining were evaluated by indexed scores at the beginning and 4th week. Markers related to gingival inflammation and oxidative stress were evaluated on samples from the gingival crevicular fluid. In the 4th week, significant improvements in clinical parameters were found in all groups (p < 0.05) with the more pronounced improvement in the CHX-MW group (p < 0.05). However, only the CHX caused a significant discolouration of both teeth and tongue (p < 0.05). The levels of IL-1β and MMP-8 were found to be lower in all groups compared to the first measurements (p < 0.05). Furthermore, the antioxidant effect of EO mouthwash was found significantly low compared to the other three mouthwashes (p < 0.05). Green and white tea extracts provided clinical benefits in the short term (1 month) with no statistical difference from each other and mouthwash with EO as the active ingredient while they provided a lower clinical benefit compared to CHX. Products with tea as the active ingredient may be an alternative to EO mouthwash for short-term and long-term use.

Relationship Between Original Research Experiences and Evidence-Based Practice Among Undergraduate Dental Hygiene Students.
For the dental hygiene profession, a need exists to engage students in research experiences as undergraduate students to foster interest in research and improve the implementation of evidence-based practice. The purpose was to explore the relationships between original research experiences and evidence-based practice among undergraduate dental hygiene students. This quantitative survey research study of undergraduate dental hygiene students in the USA was conducted in 2021. Original research experience was measured using the Wessex Research Network (WReN) spider instrument and evidence-based practice was measured using the Knowledge, Attitudes, Access and Confidence Evaluation (KACE) instrument. Invitation e-mails were sent to the directors of US entry-level dental hygiene programs to forward the survey e-mail message to students in the last semester of their dental hygiene programs. The data were analysed using descriptive statistics, bivariate analysis and multiple linear regression analysis. A total of 128 responses were analysed. The foundational knowledge domain of research experience was found to be a significant predictor of evidence-based practice and the mediators of evidence-based knowledge, evidence-based attitudes, evidence-based access and evidence-based confidence. Research experience was found to be a significant predictor of Evidence-Based Practice. Engaging undergraduate dental hygiene students in research opportunities may prepare students for the clinical application of evidence-based practice and original research projects.

Common practices of dental implant maintenance among dental hygienists working in the Netherlands - A survey.
Dental implant maintenance is crucial to obtain and maintain a healthy peri-implant situation. Although it is part of a dental hygienists (DH) scope of practice, the knowledge and common practices among DHs in the Netherlands are unclear. A web-based survey was distributed by the Dutch Association of DHs, by spreading survey QR codes and snowballing. The role of the different DH curricula 2- or 3-year diploma and a 4-year bachelor's degree is evaluated. In total, 165 (diploma: 73, bachelor: 92) DHs responded. Peri-implant diseases were well known (98%), indices and clinical symptoms were used to assess peri-implant tissues. A periodontal probe (97%) was used and bone loss was evaluated on radiographs (89%). Treatment was performed supra- and subgingivally (69%), mostly by titanium (45%) or plastic hand instruments (42%). Ultrasonic (52%) and air-abrasive (52%) devices were often used. The recall interval for maintenance was based on a risk-adjusted protocol (70%). DHs with a bachelor's received significantly more training compared to DHs with a diploma during primary education (p < 0.001). Diploma DHs mainly obtained their knowledge from continuing education (p = 0.04). In general, there was no significant difference in knowledge or common practices. The primary education of DHs with a 2- or 3-year diploma and a 4-year bachelor's varies. Due to the continuing education of diploma DHs, knowledge and common practices generally do not differ. Most DHs in the Netherlands perform implant maintenance. A periodontal probe and radiographs are used for examination. Instrumentation is performed supra- and subgingivally, usually with titanium or plastic hand instruments. The recall interval is based on a patient's risk assessment.

Effect of a powered and a manual toothbrush in subjects susceptible to gingival recession: A 36-month randomized controlled clinical study.
The objective of this long-term clinical study was to evaluate the influence of a newly developed powered toothbrush (PT) on the size and number of pre-existing gingival recessions (GR) in comparison to a manual toothbrush (MT). This was a prospective, single-blind, parallel-group, randomized controlled clinical study. Participants without periodontitis, but with at least two teeth (index teeth) showing GR ≥2 mm were randomized to brush either twice daily with a MT or with a PT with a linear magnetic drive causing the round brush head to produce gentle micro vibrations along with oscillating-rotating movements. Primary outcome parameter was the mean change of GR at the index teeth over 36 months. Totally 87 out of 92 participants completed the study (MT/PT: n = 42/n = 45). At the 36-month evaluation the mean (standard deviation) change of GR at index teeth differed significantly between MT 0.17 (0.77) and PT -0.10 (0.63) (p = 0.013). Furthermore, the amount of GR sites which improved ≥1 mm or remained stable during the study period did not differ between MT and PT, but the number of sites worsened ≥1 mm was significantly in favour for PT (MT 23 (25.5%) versus PT 10 (10.6%); p = 0.009). A binary logistic regression identified tooth type (OR = 2.991 for pre-/molar (1.096 [95% CI 1.002-8.933]; p = 0.050)) and manual brushing (OR = 3.341 (1.206 [95% CI 1291-8648]; p = 0.013)) as risk factors for recession impairment at the index teeth. There were no differences between groups for adverse events. In a population with pre-existing gingival recessions and consequently a high risk of developing further recession the PT seems to be favourable with regard to further development of GR.

Impact of air-polishing with erythritol on exposed root dentin: A randomized clinical trial.
The effects of air-polishing on exposed root dentin surfaces are largely unknown, as there are only few studies which show heterogeneous results. Thus, this study was to investigate roughness changes of exposed dentin surfaces after air-polishing and the influence of subsequent polishing with cup and paste. Totally 54 teeth with exposed root dentin surfaces were treated using a split-mouth design by either air-polishing with erythritol and a rubber cup with polishing paste on the test side, or rubber cup and paste alone. Teeth were finally cleaned using a sonic tooth brush. Impressions were taken at relevant time points and replicated using epoxy resin. The resulting casts were profilometrically analysed to obtain the average surface roughness (sRa) and maximum peak-to-valley height (sRz), which are given as the mean ± standard deviation in μm. After air-polishing, in comparison to the baseline, there was a slight but significant increase in sRa (0.168 ± 0.143, p < 0.001), but sRz did not change (-0.471 ± 4.857, p = 0.936). Subsequent polishing with cup and paste and cleaning with a sonic toothbrush did not reduce the surface roughness (sonic toothbrush-air-polishing, sRa -0.044 ± 0.081, p = 0.218; sRz -0.551 ± 3.563, p = 0.903). The use of erythritol led to a slight increase in the roughness of the dentin surface, which was not reduced by polishing with a cup and paste. Polishing paste did not seem to conceal surface irregularities.
