Introduction: Diseases of the periodontal tissues including gingivitis and periodontitis can affect up to 90% and 50% of the population respectively. These conditions are multifactorial inflammatory conditions involving a dysbiotic biofilm that, if left untreated, can lead to the destruction of the supporting structures of the teeth and have significant systemic implications, specifically on cardiovascular health. The elevation of inflammatory markers, particularly high-sensitive C-reactive protein (hsCRP), are strongly associated with an increased risk of atherosclerosis, a key risk factor for cardiovascular disease (CVD). HsCRP as well as other inflammatory markers can be detected in blood samples as early as 21 days after ceasing toothbrushing, due to the immune response to stagnant oral biofilm. The most effective way to ensure oral biofilm cannot remain on oral tissues, thus preventing periodontitis and reducing inflammatory CVD risk, is with good oral hygiene. The primary aim of this study is to assess whether individualised oral hygiene instruction (OHI) partnered with a digital oral health education (DOHE) package can improve the oral health of patients living with CVD. Methods and analysis: A total of 165 participants will be recruited from the Westmead and Blacktown Mt Druitt cardiac rehabilitation out-patient clinics into this dual centre, single blind, parallel design, randomised controlled trial. A baseline oral health clinical examination will be completed, followed by a self-report questionnaire before they are randomised in a 1:1:1 ratio into one of 3 arms as follows: individualised OHI partnered with DOHE (Group A), (Group B) DOHE only (Group B), and control/usual care (no oral health education) (Group C). Groups will have their intervention repeated at the 6-week follow-up. After completing the 12-week follow-up, Group B and Group C will receive tailored OHI. Group C will also receive the DOHE package. The primary outcome is the change in approximal plaque index score between baseline and 6-week follow up. Ethics and dissemination: The study has been approved by the Western Sydney Local Health District Human Ethics Committee 2023/ETH00516. Results will be published in peer-reviewed journals and presented at conferences. Trial registration number: ACTRN12623000449639p ANZCTR: https://www.anzctr.org.au/. [ABSTRACT FROM AUTHOR]

Objectives: To attain a collective expert opinion on the use of air powder waterjet technology (APWT) with erythritol and glycine powders in the prophylaxis and therapy of periodontal and peri‐implant diseases. Material and Methods: In the first step, a modified one‐round online Delphi survey including 44 five‐point Likert scale questions was conducted among a group of 10 expert clinicians and researchers with thorough knowledge and experience in this topic. In the second step, the single questions and the survey results were discussed during a meeting, and consensus statements were formulated, respectively. Results: An agreement was reached on most items, especially opinions supporting glycine and erythritol powders as favorable with respect to efficiency, safety, and comfort. More scientific evidence is needed to support the improvement in clinical attachment on teeth and implants, especially when APWT with erythritol is used. In addition, APWT needs more long‐term evaluation and studies in terms of microbiome/microbiological effects as well as effects on the inflammatory response on natural teeth and implants, also in light of a guided biofilm therapy concept. Conclusions: In line with the expert opinions and supported by the evidence, it was concluded that the use of APWT with erythritol and glycine powders in nonsurgical periodontal and peri‐implant therapy and prophylaxis is patient compliant and efficient.

Objective: This systematic review analyzes existing literature on the clinical efficacy of air polishing devices (APDs), discussing the evidence-based data available for justifying their use as an alternative to conventional periodontal debridement in supportive periodontal therapy. The main objective of the review was to assess whether APD was as equally efficient or superior in obtaining successful treatment outcomes when compared with conventional methods. Data Sources: Following PRISMA guidelines, a systematic literature search of articles in English, up to December 2016, was conducted using PubMed, Cochrane, and Medline. Relevant articles were selected based on specific criteria. Seven studies were selected for the final assessment. One more study was added after a manual search of the literature. Due to considerable heterogeneity in study designs and outcome variables measured, only clinical parameters (probing depth, bleeding on probing, and clinical attachment level) were selected for meta-analysis. Conclusion: The studies selected for this systematic review provide some evidence that APDs as monotherapy could be an alternative to conventional debridement of single- and multi-rooted teeth with no furcation involvement, during supportive periodontal therapy. Comparing clinical and microbiologic outcomes, APDs seem to be as effective as conventional treatments. The primary advantage for the use of APDs in supportive periodontal therapy seems to be their ability to efficiently remove biofilm, without causing damage to the periodontal soft tissues or tooth and root structure. There may also be an advantage regarding patient comfort and time consumed. [ABSTRACT FROM AUTHOR]

Periodontitis is a chronic inflammatory disease of the supportive tissues and bone surrounding the teeth. In severe cases, it can consequently lead to tooth loss. This disease is most prevalent in rural and remote communities where regular dental visits are limited. Hence, there's a need for a periodontal screening tool for use by allied health professionals outside of dental clinics to detect periodontitis for early referral and intervention. In this paper two algorithms have been proposed and applied on two independently collected datasets in Germany and Australia with 20 and 24 participating subjects respectively; in the first algorithm, intra-oral images of before periodontitis treatment have been considered as diseased subjects and the images of after treatment have been considered as healthy subjects. Using the histogram of pixel intensity as our classification feature, the healthy and diseased subjects have been classified with an accuracy of 66.7%. In the second algorithm, using the difference between the histograms as our classification features, images of "before" and "after" treatment have been classified with an accuracy of 91.6%. If used in a smart phone application, the first algorithm can help people with limited access to dental clinics to be screened for periodontitis by allied health professionals in any healthcare setting. The second algorithm may be useful in helping non-dental personnel to monitor the progress of periodontal treatment.
