Primary stability of dental implants installed using osseodensification or bone expansion drilling systems: a comparative clinical study
Aim: Primary stability of dental implants is a prerequisite for osseointegration, and the osteotomy technique is one of the factors that may alter it. The aim of this study was to compare the primary stability of dental implants installed using osseodensification and bone expansion drilling systems. Materials and Methods: This split-mouth comparative clinical study included 12 patients. Each patient received one implant for each of the tested systems, totaling 24 implants. Implants were installed in edentulous areas with space for two adjacent implants or in two similar contralateral areas...

Aim: De-epithelialized gingival graft (DGG) is recommended due to its simplicity and successful outcomes. However, donor site morbidity still poses a problem. The aim of this trial was to evaluate the effectiveness of gelatin sponge-cyanoacrylate (GS-CY) combination at donor site healing. Materials and Methods: DGG donor sites were treated with either GS (control) (n=21) or GS+CY (test) (n=21). Palatal tissue thickness, graft dimensions, working time (WT), primary bleeding time were...
Aim: To investigate self-reported short-term morbidity after the application of advanced platelet rich fibrin (A-PRF+) in combination with periodontal regenerative microsurgery in molar furcations and compare this the use of enamel matrix derivative application (EMD) or open flap debridement (OFD, control). Materials and Methods: A prospective randomized controlled trial was designed to study effects of A-PRF+, EMD or control for pocket closure of molar furcations grade II. Patients were...
Aim: To examine the clinical effects of subgingival instrumentation with the application of a 2% minocycline hydrochloride controlled-delivery system in residual deep pockets of supportive periodontal therapy (SPT) patients. Materials and Methods: Patients undergoing SPT were recruited in this randomized, double- blinded controlled trial. Clinical data were collected by blinded periodontists at baseline, 3, 6, 9, and 12 months. All patients were treated with mechanical debridement. Intervention...
Aim: It has been shown that periodontitis increases systemic inflammation, which in turn up-regulates vascular cyclooxygenase-2 (COX-2). We hypothesised that an increase in vascular COX-2 expression plays a role in vascular homeostasis. Thus, we analysed the effect of COX-2 inhibition in an experimental infarction model in rats with periodontitis. Materials and Methods: Wistar rats were subjected to ligature-induced experimental periodontitis or sham procedure. After 12 days of induction of...
Aim: The primary aim of this randomized split-mouth triple-blind placebo-controlled clinical trial was to assess, by means of cone-beam computed tomography (CBCT), the effect of surgical topical use of 1%- Sodium alendronate (ALN) on the reduction of periodontal intrabony defects. Material and methods: Sixty-four intrabony defects from 32 patients with periodontitis were randomly treated with either 1%-ALN gel or placebo gel during periodontal surgeries. Periodontal clinical parameters were...
Aim: This study aims to evaluate linear bone loss (LBL) and connective tissue attachment loss (CTAL) in animals suffering from ligature-induced periodontitis (P), either associated with orthodontic tooth movement (OTM) and cigarette smoking or not. Material and methods: Fifty-six male Wistar rats were allocated into two groups in smoking and non-smoking conditions. Each group has been subdivided into the following: control (C), OTM, P, and P+OTM (POTM). Periodontitis has been induced in the...

Aim: Pain management after periodontal surgery has been discussed in relation to drug classification; however, analgesia protocols have not been addressed. Thus, the objective of this systematic review (SR) was to compare preoperative and postoperative analgesia protocols for postoperative pain control in periodontal surgery. Materials and Methods: This SR was developed according to PRISMA statements. Electronic databases and gray literature were investigated regarding trials using...
