Background: This single-centered randomized controlled clinical trial aimed to evaluate the effectiveness of micro-osteoperforations (MOPs) in accelerating the orthodontic retraction of maxillary incisors.

Methods: Forty-two patients aged 16-40 were recruited and randomly assigned into two groups, one which underwent MOPs (MOPG) in the buccal and palatal region of all maxillary incisors immediately before the start of retraction and one which did not (CG). Eligibility criteria included the orthodontic need for maxillary first premolars extraction and space closure in two phases.

Craniofacial morphology of patients with unilateral cleft lip and palate at two stages of skeletal maturation.

The aim of this retrospective cross-sectional investigation was to perform a 3D analysis of craniofacial morphology of patients with unilateral cleft lip and palate (UCLP) at two stages of skeletal maturation. Cone-beam computed tomography (CBCT) scans of 52 UCLP patients (34 prepubertal; 18 pubertal) were collected from an outpatient referral center for the treatment of craniofacial deformities. In total 15 multiplanar craniofacial landmarks were identified, 3D virtual surface models were created, and 13 variables were measured to assess the 3D Euclidean distances between landmarks and spatial position of the landmarks in the projected X, Y and Z components.

Methods: A cross-sectional study was conducted with a representative sample of 633 children aged 7-12 years.

The blockade of kappa opioid receptors exacerbates alveolar bone resorption in rats.

Objectives: Bone resorption associated to chronic diseases, such as arthritis and periodontitis, results from exacerbated immuno-inflammatory host response that leads to tissue breakdown. The significance of opioid pathways as endogenous modulators of inflammatory events has already been described. Thus, the aim of this work is to determine whether some of the main three opioid receptors are endogenously activated to prevent bone loss during experimentally-induced alveolar bone resorption.

Background: The aim of this systematic review was to evaluate the effects of piezocision in accelerating orthodontic tooth movement (OTM) and its possible adverse effects.

Material And Methods: The Databases Medline, Embase, CENTRAL and LILACS were searched until March 2019, for randomized controlled trials (RCTs) and controlled clinical trials (CCTs) that used piezocision associated with orthodontic treatment. A manual search was also performed.

Effect of porous tantalum on the biological response of human peripheral mononuclear cells exposed to Porphyromonas gingivalis.

Aim: To evaluate biological behavior of human peripheral mononuclear cells (PBMC) in contact with porous tantalum (PT) and Porphyromonas gingivalis (Pg).

Methods: Pg was incubated for 8 hours. The groups formed were: PBMC (control), PBMC + PT, PBMC + Pg and PBMC + PT + Pg.

Successful and stable orthodontic camouflage of a mandibular asymmetry with sliding jigs.

The purpose of this paper is to present and discuss a simple and low-cost clinical approach to correct an asymmetric skeletal Class III combined to an extensive dental open bite that significantly compromised the occlusal function and smile aesthetics of an adult male patient. The patient did not accept the idealistic surgical-orthodontic treatment option, neither the use of temporary anchorage devices to facilitate the camouflage of the asymmetrical skeletal Class III/open bite. Therefore, a very simple and inexpensive biomechanical approach using sliding jigs in the mandibular arch was implemented as the compensatory treatment of the malocclusion.

Plaque index and gingival index during rapid maxillary expansion of patients with unilateral cleft lip and palate.

Objective: To assess, during rapid maxillary expansion, the plaque index (PI) and the gingival index (GI) of patients with unilateral cleft lip and palate(UCLP) using Hyrax (HX) or inverted mini-Hyrax (IMHX) rapid maxillary expanders (RME) considering patients' sex and age.

Methods: PI (Quigley Index modified by Turesky et al) and GI (Löe and Silness) of 28 UCLP (11 females; 17 males: aged 8 to 15 years) submitted to daily RME activation were assessed before (T0) and 7 (T1), 28 (T2) and 90 (T3) days after activation. Log-linear models and Bonferroni correction were performed to analyze possible differences in PI and GI between RME, sexes or age groups over time.

Oral Lichen Sclerosus: A Rare Case Report and Review of the Literature.

Lichen sclerosus (LS) is a chronic inflammatory mucocutaneous disease that often affects the anogenital area and causes significant discomfort and morbidity. Oral mucosal lesions in LS are extremely rare and might be associated with genital and/or skin manifestations. As a unique manifestation of LS, oral lesions are even more rare, with only 20 cases reported in English-language literature.

Effect of vegetable oil (Brazil nut oil) and mineral oil (liquid petrolatum) on dental biofilm control.

Dental biofilm control represents a basic procedure to prevent caries and the occurrence of periodontal diseases. Currently, toothbrushes and dentifrices are used almost universally, and the employment of good oral hygiene allows for appropriate biofilm removal by both mechanical and chemical control. The aim of this study was to evaluate the effectiveness of adding vegetable or mineral oil to a commercially available dentifrice in dental biofilm control.
