The purpose of this study was to compare the efficacy between the use of bovine bone graft material and platelet-rich fibrin (PRF) mixture (test group) and bovine bone graft material and collagen membrane combination (control group) in 2-stage maxillary sinus augmentation. According to specific inclusion/exclusion criteria, patients treated between 2008 and 2012 were selected. Panoramic radiographs were used for radiologic assessments.

The comparison of acellular dermal matrix allografts with free gingival grafts in the augmentation of peri-implant attached mucosa: a randomised controlled trial.

Purpose: The purpose of this randomised controlled trial is to compare the efficacy of two techniques for enhancing peri-implant keratinised mucosa: acellular dermal matrix allograft versus free gingival grafts.

Materials And Methods: Thirty-six patients having implant sites with less than 1.5 mm of keratinised mucosa width were randomly assigned to two groups.

Clinical evaluation of marginal bone loss and stability in two types of submerged dental implants.

Purpose: The aim of this prospective clinical trial was to compare the three-dimensional marginal bone level, implant stability, and peri-implant health of two types of submerged dental implants that were restored with matching or platform-switched abutments.

Materials And Methods: Twenty-five subjects were recruited (test group: 43 implants with internal conical connection and back-tapered collar carrying a platform-switched abutment; control group: 50 implants carrying a matched-platform abutment). Implant uncovering and conventional loading were performed after 3 months of healing, and the total observation time was 15 months.

Efficacy of quick-release lornoxicam versus placebo for acute pain management after dental implant surgery: a randomised placebo-controlled triple-blind trial.

Aim: To assess the efficacy of quick-release lornoxicam (LNX) on patient-reported acute pain after dental implant surgery.

Materials And Methods: The study included subjects in good general health, aged 18 to 65 and scheduled to receive a maximum of three implants in the same quadrant. Participants received either 8 mg LNX or placebo and were asked to use the medications in case of pain in the first 120 min after implant surgery.

The comparison of two techniques to increase the amount of peri-implant attached mucosa: free gingival grafts versus vestibuloplasty. One-year results from a randomised controlled trial.

Aims: The objective of this randomised controlled trial was to compare the efficacy of two techniques for increasing the amount of keratinised mucosa around implants: free gingival grafts versus classic vestibuloplasty.

Materials And Methods: Sixty-four patients with 64 implants presenting keratinised mucosa <1.5 mm and showing signs of peri-implant mucositis were randomly assigned to two groups.

Evaluation of periimplant crevicular fluid prostaglandin E2 and matrix metalloproteinase-8 levels from health to periimplant disease status: a prospective study.

Objective: To compare the levels of prostaglandin E2 (PGE2) and matrix metalloproteinases-8 (MMP-8) in periimplant crevicular fluid (PICF) after osseointegration and loading.

Materials And Methods: PICF was collected at the 3rd, 6th, 12th, and 18th months after implantation of 72 implants. PGE2 and MMP-8 levels besides clinical parameters were evaluated.

Detection of crestal radiolucencies around dental implants: an in vitro experimental study.

Purpose: The aim of this study was to compare the diagnostic potentials and practical advantages of different imaging modalities in detecting bone defects around dental implants.

Materials And Methods: Crestal bone defects with sequentially larger diameters were randomly prepared around 100 implants that were inserted in bovine bone blocks. Conventional periapical radiography (PR), direct digital radiography (DDR), panoramic radiography (PANO), cone-beam computed tomography (CBCT), and multislice computed tomography (MSCT) were performed for all specimens.

Clinical and biochemical efficacy of minocycline in nonsurgical periodontal therapy: a randomized controlled pilot study.

The present study evaluated the effects of systemic minocycline on clinical and biochemical parameters of chronic periodontitis, which is a common inflammatory disorder of the periodontium initiated by the presence of bacteria in the gingival sulcus. Besides nonsurgical periodontal therapy, 20 individuals received minocycline systemically while another 20 subjects received placebo capsules for 2 weeks. Plaque index (PI), sulcus bleeding index (SBI), probing depth (PD), and relative attachment level (RAL) were measured and gingival crevicular fluid (GCF) samples were obtained at baseline and first, third, and sixth months.

Detection of implant crevicular fluid prostaglandin E2 levels for the assessment of peri-implant health: a pilot study.

Inflammatory changes in the peri-implant tissues may lead to peri-implantitis and bone loss. Prostaglandin E2 has been shown to have proinflammatory effects on peri-implant tissues, including mediation of bone resorption. The aim of this study was to assess prostaglandin E2 levels in implant crevicular fluid and the possibility of using this method in diagnosing peri-implant mucositis.

The effect of sociocultural status on periodontal conditions in pregnancy.

Background: The effects of sociocultural status on periodontal conditions in pregnant women have been reported by a number of researchers and there have been speculations about the effects of hormonal changes, patients' systemic health, and socio-cultural characteristics on periodontal health during pregnancy.

Methods: This study evaluates the periodontal condition of 61 pregnant women at their first, second, and third trimesters, and the relation between the demographic (age, professional level, education) and clinical variables (previous periodontal care, frequency of tooth brushing). The clinical indices, including plaque index, gingival index, and probing depth measurements were repeated at the first, second, and third trimesters.

The effects of periodontal therapy on intracrevicular prostaglandin E2 concentrations and clinical parameters in pregnancy.

Background: The increase in circulating levels of progesterone during pregnancy stimulates production of prostaglandins, especially prostaglandin E2, possibly resulting in pregnancy gingivitis. The purpose of this study is to evaluate the influence of prostaglandin E2 concentrations on gingival tissues in pregnancy and to assess its relationship to clinical parameters.

Methods: This study evaluates the effects of periodontal treatment on clinical indices including plaque index, gingival index, probing depth, and gingival crevicular fluid prostaglandin E2 levels of 22 pregnant women in their first, second, and third trimesters.
