Four single implant-supported crowns replacing the maxillary incisors: A retrospective report of 10 cases with 2-9 years of follow-up.

Objective: This retrospective case series aimed to assess the stability of the papilla around four single crowns supported by narrow-diameter implants replacing all maxillary incisors. Secondary objectives included assessment of marginal bone level stability, incidence of technical and biological complications, and patient satisfaction.

Materials And Methods: Individuals with four adjacent implants in maxillary incisor sites, placed with a 3 mm inter-implant distance and rehabilitated with single crowns were included.

The effect of Brazilian propolis type-3 against oral microbiota and volatile sulfur compounds in subjects with morning breath malodor.

Objectives: To evaluate propolis type-3 mouthrinse effects on the concentration of volatile sulfur compounds (VSCs) and on tongue dorsum microbial profile.

Materials And Methods: A three-step double-blind, crossover, randomized study with 10 individuals divided into three groups: I-placebo (P); II-ethanolic extract of propolis type-3 3% (EEP); and III-chlorhexidine 0.12% (CHX) and instructed to rinse twice daily for 5 days.

Accuracy of High-resolution Small-volume Cone-Beam Computed Tomography in the Diagnosis of Vertical Root Fracture: An In Vivo Analysis.

Introduction: The purpose of this in vivo study was to evaluate the accuracy of small-volume cone-beam computed tomographic (CBCT) imaging compared with conventional periapical radiography (CPR) in the diagnosis of vertical root fractures (VRFs) using exploratory surgery as the reference standard.

Methods: Eighty-two dental records of 85 teeth with suspected VRFs that underwent CPR, CBCT imaging, and exploratory surgery were included. Two observers assessed CPR and CBCT images independently for the presence or absence of root fractures, and findings from the exploratory surgery were considered the reference standard.

Periodontal parameters of two types of 3 x 3 orthodontic retainer: a longitudinal study.

Introduction: bonded fixed retainers are often used to stabilize the results obtained with the orthodontic treatment. It is important that they do not prejudice dental health, as they will be used for a long period.

Objective: The purpose of the present study was to compare periodontal indexes between two types of bonded fixed retainers, conventional 3 x 3 plain retainer (0.

Effect of toothbrushing discontinuation on morning volatile sulfur compounds in periodontally healthy subjects.

Purpose: To follow up the variations of early morning concentrations of oral volatile sulfur compounds (VSCs) in periodontally healthy subjects who refrained from toothbrushing during a period of 5 days while continuing with other hygiene procedures.

Materials And Methods: Thirteen subjects volunteered for this study. At baseline, all subjects stopped brushing their teeth for 5 days, but continued using dental floss and a tongue scraper twice daily.

Congenitally missing maxillary lateral incisors: functional and periodontal aspects in patients treated with implants or space closure and tooth re-contouring.

To evaluate functional and periodontal aspects in patients with unilateral or bilateral congenitally missing maxillary lateral incisors, treated with either implants or space closure and tooth re-contouring. The sample consisted of 68 volunteers, divided into 3 groups: SCR - space closure and tooth re-contouring with composite resin (n = 26); SOI - implants placed in the area of agenesis (n = 20); and CG - control group (n = 22). A modified Helkimo questionnaire and the Research Diagnostic Criteria for Temporomandibular Disorders were used by a single, previously calibrated evaluator to assess signs and symptoms of temporomandibular joint disorder.

The success rate of immediate implant placement of mandibular molars: a clinical and radiographic retrospective evaluation between 2 and 8 years.

Background: Dental implants, indicated for re-establishing both mastigatory and aesthetic functions, can be placed in the sockets immediately after tooth extraction. Most studies investigate the anterior and upper regions of the dental arch, whereas few examine longitudinal appraisal of immediate implant installation in the mandibular molar region.

Objective: The aim of this retrospective study was to evaluate the success rate of immediate dental implants placement in mandibular molars within a follow-up period as long as 8 years.

Interdisciplinary treatment for a patient with open-bite malocclusion and amelogenesis imperfecta.

Amelogenesis imperfecta (AI) comprises a clinically and genetically heterogeneous group of conditions that affect the dental enamel, occasionally in conjunction with other dental, oral, and extraoral tissues. The aim of this case report is to describe an interdisciplinary treatment of hypoplastic AI associated with a severe open bite. The treatment consisted of surgical, orthodontic, periodontal, prosthetic and restorative management, establishing good chewing function, dental esthetics and facial harmony.

Periodontal parameters and BANA test in patients with chronic renal failure undergoing hemodialysis.

Objectives: The aim of this study was to analyze the periodontal parameters of patients with chronic renal failure.

Material And Methods: The periodontal status of 16 Brazilian patients aged 29 to 53 (41.7 ± 7.

A cross-over study on the effect of various therapeutic approaches to morning breath odour.

Objective: The aim of this study was to investigate the effect of tongue scraping and inter-dental flossing on morning bad breath in periodontally healthy subjects.

Methods: A four-step blind, cross-over study was conducted in 19 volunteers, divided into four groups: Group I: tooth brushing; Group II: tooth brushing and inter-dental flossing; Group III: tooth brushing and tongue scraping; and Group IV: tooth brushing, inter-dental flossing and tongue scraping. The volunteers performed these oral hygiene procedures three times a day for 7 days.
