Efficacy of Mucograft vs Conventional Resorbable Collagen Membranes in Guided Bone Regeneration Around Standardized Calvarial Defects in Rats: A Histologic and Biomechanical Assessment.

Guided bone regeneration (GBR) using a porcine-derived collagen matrix (Mucograft [MG], Geistlich) has not yet been reported. The aim of this histologic and biomechanical study was to compare the efficacy of MG versus resorbable collagen membranes (RCMs) in facilitating GBR around standardized rat calvarial defects. Forty female Wistar albino rats with a mean age and weight of 6 to 9 weeks and 250 to 300 g, respectively, were used.

Efficacy of Mucograft vs Conventional Resorbable Collagen Membranes in Guided Bone Regeneration Around Standardized Calvarial Defects in Rats: An In Vivo Microcomputed Tomographic Analysis.

The aim of this in vivo microcomputed tomographic (μCT) study was to compare the efficacy of Mucograft (MG) vs resorbable collagen membranes (RCMs) in facilitating guided bone regeneration (GBR) around standardized calvarial defects in rats. Forty female Wistar albino rats with a mean age and weight of 6 to 9 weeks and 250 to 300 g, respectively, were used. With the rats under general anesthesia, the skin over the calvaria was exposed using a full-thickness flap.

Histologic assessment of alveolar bone remodeling around immediate implants placed in single and multiple contiguous extraction sites.

The aim of this study was to histologically assess alveolar bone remodeling around immediate implants placed in single and multiple contiguous extraction sites. Ten dogs were divided into three groups (with six sites per group) on the basis of premolar teeth extraction: group 1 = one tooth extracted, group 2 = two contiguous teeth extracted, and group 3 = more than two contiguous teeth extracted. Immediate implants were placed in each group.

Bone morphology changes around two types of bone-level implants installed in fresh extraction sockets--a histomorphometric study in Beagle dogs.

Background: Minimizing crestal bone loss following immediate implant placement is considered the most challenging aspect in implant therapy. Implant surface topography and chemical modifications have been shown to influence the success of Osseointegration. The Straumann Bone Level implant, featuring SLActive surface, has been introduced with the aim of enhancing bone apposition.

Microcomputed tomographic analysis of the alveolar ridge alteration around extraction sites with and without immediate implants placement: in vivo study.

Background: The aim was to assess the alveolar ridge alteration around extraction sites with and without immediate implants according to extraction socket classification (ESC) using microcomputed tomography (micro-CT).

Material And Methods: Ten beagle dogs (mean age and weight: 24 ± 0.83 months and 13.

Efficacy of using PDGF and xenograft with or without collagen membrane for bone regeneration around immediate implants with induced dehiscence-type defects: a microcomputed tomographic study in dogs.

Background: Use of collagen membrane (CM) with xenograft and recombinant human platelet-derived growth factor (rhPDGF) in guided bone regeneration (GBR) is debatable. The aim of this microcomputed tomographic experiment was to assess the efficacy of using PDGF and xenograft (with or without CM) for GBR around immediate implants with dehiscence defects.

Methods: Ten beagle dogs underwent atraumatic bilateral second and fourth premolar extractions from both arches.

Alveolar bone remodeling around immediate implants placed in accordance with the extraction socket classification: a three-dimensional microcomputed tomography analysis.

Background: Previous studies assessed bone remodeling after a single tooth extraction; however, the effect of multiple contiguous teeth extractions around immediate implant remains unknown. The aim of this microcomputed tomographic investigation is to analyze the alveolar bone remodeling around immediate implants placed in accordance with the extraction socket classification (ESC).

Methods: Under general anesthesia, 10 beagle dogs underwent atraumatic tooth extractions.

Comparison of self-perceived oral health, periodontal inflammatory conditions and socioeconomic status in individuals with and without prediabetes.

Introduction: The aim was to compare the self-perceived oral health, periodontal inflammatory conditions and socioeconomic status (SES) in patients with and without prediabetes.

Methods: Thirty-nine individuals [19 patients with prediabetes (test group) and 20 control individuals (control group)], at least 20 years old were included. Plaque index, bleeding on probing, probing depth (4 to <6 mm and ≥6 mm) and number of missing teeth were recorded.

The effect of locally delivered doxycycline as an adjunctive therapy to scaling and root planing in smokers.

Background: Locally delivered doxycycline is found to be effective in managing periodontitis as an adjunct to scaling and root planing.

Aim: To evaluate the effect of locally delivered doxycycline (10%) with scaling and root planing in the periodontal treatment of smokers and to compare it with scaling and root planing alone.

Methods: Twelve smokers with chronic periodontitis and a pocket depth (⩾5 mm) on posterior teeth that bleed on probing were selected.

Healing of peri-implant tissues after flapless and flapped implant installation.

Aim: The aim of this study was to investigate the consequences of different flapless procedures for the installation of dental implants on peri-implant bone response.

Materials And Methods: After bilateral extraction of the mandibular second and third premolars and a 3-month healing period, 30 SLActive(®) implants were installed for 3 months in 10 Beagle dogs according to three different surgical approaches, i.e.

The use of povidone-iodine and hydrogen peroxide mixture as an adjunct to non-surgical treatment of slight to moderate chronic periodontitis.

Objective: The aim of this study was to evaluate the clinical effects of the adjunctive use of povidone-iodine with or without hydrogen peroxide as coolant and disinfectant during ultrasonic scaling and root planing in the treatment of chronic periodontitis.

Materials And Methods: Sixteen patients initially participated in the study. Thirteen patients (8 males and 5 females) completed the 3-month follow-up period.

Surgical management of gingival recession: A clinical update.

Gingival recession is defined as the apical migration of the junctional epithelium with exposure of root surfaces. It is a common condition seen in both dentally aware populations and those with limited access to dental care. The etiology of the condition is multifactorial but is commonly associated with underlying alveolar morphology, tooth brushing, mechanical trauma and periodontal disease.

Assessment of lipid profile in Saudi type 2 diabetic and non-diabetic periodontal patients.

Objective: To study the extent of periodontal disease in diabetic and non-diabetic periodontitis patients, and to investigate the relationship of dyslipidemia and periodontal disease, in diabetic and non-diabetic periodontitis patients.

Methods: This is a cross-sectional study at the Department of Preventive Dental Sciences (College of Dentistry) and Department of Physiology (College of Medicine), King Saud University, Riyadh, Kingdom of Saudi Arabia, from February 2003 to June 2004. A total of 90 patients was recruited, and divided into 3 equal groups of 30 subjects, with age and gender matched, and divided as follows: group 1 healthy group: periodontally and systemically healthy subjects, group 2 periodontitis group: chronic periodontitis patients with no systemic disease, group 3 diabetic group: chronic periodontitis patients with type 2 diabetes mellitus.
