Influence of mineralized and demineralized xenograft bone on the repair of intraoral bone defect in rats
Introduction: Mineralized bovine bone grafts have been widely used as substitutes for bone losses in dental clinics. Studies have shown that exposing the organic components of the bone matrix at surgical sites accelerates bone deposition. Objective: The present study evaluated the bone repair progress of an intraoral bone defect in rats after grafting with mineralized (MBB) and demineralized bovine bone (DBB). Materials and Methods: An intraoral bone defect was created after extraction of the right maxillary first molar, drilling the area of the alveoli of the four distal roots using a...

Introduction: Necrotizing periodontal diseases (NPD) are acute lesions with a rapid onset that may cause considerable periodontal tissue destruction. Among these conditions, necrotizing gingivitis (NG) is caused by microorganisms from the oral biofilm, and is associated with predisposing factors such as psychological stress, HIV/AIDS, alcohol and tobacco consumption, malnutrition, inadequate oral hygiene, and other systemic conditions that may compromise the host immune response....
Objective: This study aimed to evaluate self-esteem and patient’s satisfaction before and after surgical correction of altered passive eruption (APE) type 1B in the anterior maxilla, in a three and 18-months follow-up; and postoperative pain and discomfort. Materials and Methods: Twelve individuals (mean age 23.3±4.2 years) were submitted to gingivoplasty, osteoplasty and osteotomy, and answered to questionnaires including the Visual Analog Scale (0-10). Results: At baseline, patients...
Introduction: Antimicrobial photodynamic therapy (aPDT) is an adjuvant treatment for periodontal disease. Methylene blue (MB) and toluidine blue O (TBO) are commonly used as photosensitizers in aPDT. However, the pH of blue dyes is a rarely discussed topic. Objectives: The aim of this study was to evaluate dentin demineralization and optical properties of acidified (pH1) MB and TBO. A secondary objective of this paper was to discuss the regular pH of blue photosensitizers and their clinical...

Objective: To analyze the association between sleep duration and periodontal parameters in older adults. Materials and Methods: Data from 1,136 community-resident older adults participating in the Health, Aging and Body Composition (Health ABC) Study were used. Hours of sleep per night were determined by self-report. Probing pocket depth (PPD) and clinical attachment level (CAL) were evaluated for all teeth present. Periodontal disease was categorized, considering different cut-points of PPD...
Objective: The present prospective randomized clinical study compared the use of Dermabond® tissue adhesive as a substitute for sutures, in free gingival graft fixation. Materials and Methods: Twenty individuals with absence of keratinized mucosa (KM) or KM height less than 1.0 mm in the buccal area of the mandibular incisors were selected to receive free gingival grafts. The patients were distributed into two groups: G1, composed by 8 patients with 10-mm grafts fixed with sutures; G2,...
