Does adopting a healthy diet improve periodontal parameters in patients susceptible to periodontal disease? A systematic review.

Objectives: The aim of this systematic review is to evaluate evidence relating to whether adopting a diet, associated with improved outcomes for chronic systemic diseases with an inflammatory component, can improve periodontal parameters in patients with periodontal diseases.

Data Sources: Electronic databases and one platform were systematically searched; Medline, Embase, Web of Science and the Cochrane Library including references of relevant studies.

Data Selection And Extraction: 1220 studies were identified of which 9 studies were eligible; 4 RCT's, 1 controlled trial and 4 observational cohort studies DATA SYNTHESIS: 8 out of 9 studies found improved periodontal parameters associated with a diet that was low in refined carbohydrates, low in saturated fats, high in fibre and high in nutrition but the studies were low to medium quality of evidence and the diets, method of recording the diets and periodontal parameters varied between the studies as did the study duration and age of participants.

Lithium disilicate, full coverage crowns: what is the effect of using conventional impressions compared to digital impression with respect to the internal fit of the restoration? A systematic review.

Purpose: Digital dentistry provides an alternative to fabrication of crowns. This systematic review focuses on the accuracy of the mean internal space of lithium disilicate crowns when comparing intraoral scanning to conventional impressions.

Methods: Ovid Medline, Cochrane and PUBMED were searched and the review protocol followed the International Prospective Register of Systematic Reviews (PROSPERO) (CRD42023379908) and guided by The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA).
