1. Comparison between calcium hydroxide mixtures and mineral trioxide aggregate in primary teeth pulpotomy: a randomized controlled trial
Abstract Objectives: To evaluate the effect of calcium hydroxide (CH) associated with two different vehicles as a capping material for pulp tissue in primary molars, compared with mineral trioxide aggregate (MTA). Methodology: Forty-five primary mandibular molars with dental caries were treated by conventional pulpotomy using one of the following materials

2. Sampling strategy of an epidemiological survey using a satellite image program
ABSTRACT OBJECTIVE To describe the sampling strategy of an epidemiological survey with the aid of satellite images, including details of the multistage probability sampling process. METHODS A probability sample of individuals living in the rural area of Rosário do Sul, state of Rio Grande do Sul, Brazil, aged 15 years old or more, was evaluated. Participa

3. Effects of avocado/soybean unsaponifiables (ASU) on the treatment of ligature-induced periodontitis in rats
Abstract The purpose of this study is to evaluate the effect of the avocado/soybean unsaponifiables (ASU) on the treatment of induced periodontitis in rats. Periodontitis was induced in 84 rats via ligature placement around the second upper molar, which was removed after 7 days, and scaling and root planning (SRP) was performed at this time. Subsequently, th

4. Morphological Study and Analysis of Microhardness and Permeability of the Furcation of Maxillary Premolars
Resumo Estudou-se a morfologia, microdureza e permeabilidade dentinária da furca de pré-molares superiores. Dez pré-molares tiveram a porção oclusal da coroa e os terços radiculares médio e apical removidos. Cortou-se longitudinalmente o remanescente e delimitou-se a furca. As hemi-secções foram distribuídas em dois grupos. Num (n=10), mediu-se a m

5. Shaping ability of rotatory or reciprocating instruments in curved canals: a micro-computed tomographic study
Abstract This study aimed to compare apical transportation, centering ratio, and working time during root canal preparation with Wizard Navigator (WN), WaveOne (WO), or ProTaper Universal (PT) and to describe deformation and fracture of these instruments. Thirty-six mesiobuccal roots from maxillary molars were micro-computed tomography (micro-CT) scanned and

6. Rotation axis of the maxillary molar and maximum tooth movement according to force direction
Aim: To evaluate the correlation between the maxillary molar rotation center and the direction of the maximum tooth movement according to the force direction using three-dimensional finite element analysis (3D-FEA).
Methods: Computed tomography of a human tooth was used to build a finite element model, w

7. Evaluation of technical quality and periapical health of root-filled teeth by using cone-beam CT
Objective This study aimed to assess the quality of root fillings, coronal restorations, complications of all root-filled teeth and their association with apical periodontitis (AP) detected by cone-beam computed tomography (CBCT) images from an adult Turkish subpopulation. Material and Methods The sample for this study consisted of 242 patients (aging f

8. Effects of alcohol intake in periodontitis progression in female rats: a histometric study
AIM: To evaluate histometrically the effect of low and high caloric value of ethanol on ligature-induced bone loss in female rats. METHODS: Sixty female rats were divided into five groups of 12 animals each: Normal Control (water), Test A (low ethanol), Control A (low iso), Test B (high ethanol) and Control B (high iso). Control Groups A and B received

9. Influence of ovariectomy combined with lack of masticatory force in the evolution of periodontal disease
AIM: To evaluate the influence of ovariectomy combined with lack of masticatory force in the evolution of periodontal disease induced in rats. METHODS: Forty rats were bilaterally ovariectomized and 40 were submitted to sham ovariectomy. Periodontal disease was induced in the mandibular left first molar and the maxillary left first molar was extracted fr

10. Clinical and radiographic evaluation of Bio-Gen with biocollagen compared with Bio-Gen with connective tissue in the treatment of class II furcation defects: a randomized clinical trial
OBJECTIVE: Treatment of furcation defects are thought to be challenging. The purpose of this study was to evaluate the clinical and radiographic parameters of Bio-Gen with Biocollagen compared with Bio-Gen with connective tissue in the treatment of Class II furcation defects. MATERIAL AND METHODS: In this clinical trial, 24 patients with Class II furca

11. Effect of Early Membrane Removal on the Treatment of Mandibular Class II Furcation Defects - A Controlled Clinical Trial with Re-entry after 12 Months
Em estudo prévio, em cães, a remoção precoce da membrana de politetrafluoretileno expandido (PTFE-e), 2 semanas após a colocação, mostrou resultados histomorfométricos (formação de novo osso, cemento e ligamento periodontal) similares aos de remoção da membrana 4 semanas após a sua colocação. Este estudo avaliou a influência da remoção prec

12. Detection of simulated incipient furcation involvement by CBCT: an in vitro study using pig mandibles
The aim of the present study was to test the reproducibility, sensitivity, and specificity of cone-beam computed tomography (CBCT) in detecting incipient furcation involvement. Fifteen macerated pig mandibles, with intact second molar teeth and preserved adjacent cortical areas, were used. Simulated lesions were created in the furcation region of these teeth
