Effect of subgingival periodontal therapy on glycaemic control in type 2 diabetes patients: Meta-analysis and meta-regression of 6-month follow-up randomized clinical trials.

Background: Periodontitis worsens the hyperglycaemia in patients with type 2 diabetes mellitus (T2DM). Subgingival instrumentation, with or without surgical access, is the gold-standard treatment for periodontitis. The aim was to summarize the evidence on the effect of subgingival instrumentation (with or without open flap) on the reduction of glycosylated haemoglobin (HbA1c).

What is the future of Periodontal Medicine?

In the last five decades, considerable progress has been made towards understanding the etiology and pathogenesis of periodontal diseases and their interactions with the host. The impact of an individual periodontal condition on systemic homeostasis became more evident because of this knowledge and prompted advances in studies that associate periodontitis with systemic diseases and conditions. The term Periodontal Medicine describes how periodontal infection/inflammation can affect extraoral health.

Influence of abutment disconnection on peri-implant marginal bone loss: A randomized clinical trial.

Objectives: To evaluate the influence of abutment disconnections and reconnections on peri-implant marginal bone loss.

Material And Methods: Twenty-four participants received single-unit implants and were randomly assigned into one of the two groups: the definitive abutment group (DEF), in which the definitive abutments were connected at the same time as the implant was inserted; and as a control, the healing abutment group (HEA), in which the healing abutments were disconnected and reconnected three times, at 8, 10, and 12 weeks after surgery. Peri-implant marginal bone level was measured through radiographic follow-up performed immediately after the surgery (baseline), at 8 weeks and after 6, 12, and 24 months.

Accuracy of single crowns fabricated from ultrasound digital impressions.

Objective: This in vitro study aimed to evaluate marginal and internal fit of single crowns produced from high-frequency ultrasound based digital impressions of teeth prepared with finish lines covered by porcine gingiva, in comparison with those obtained by optical scanners with uncovered finish lines.

Restoring esthetics in eroded anterior teeth: a conservative multidisciplinary approach.

Consuming a highly acidic diet can lead to erosion or excessive wear of dental hard tissues, resulting in the need for oral rehabilitation. Previously, a severely eroded dentition could be rehabilitated only by extensive crown and bridge placement or by removable partial dentures. However, developments in adhesive dentistry have made it possible to restore the esthetics and function of eroded teeth in a minimally invasive manner.
