Overbite depth indicator and anteroposterior dysplasia indicator cephalometric norms for African Americans.

Overbite depth indicator and anteroposterior dysplasia indicator cephalometric norms for African Americans. Angle Orthod. 2019 Jul 15;: Authors: Obamiyi S, Wang Z, Sommers E, Rossouw PE, Michelogiannakis D Abstract OBJECTIVES: To examine normal Overbite Depth Indicator (ODI) and Anteroposterior Dysplasia Indicator (APDI) values in African Americans and to compare them with mean values from white patients. Secondary aims were to compare mean ODI and APDI values among different age, gender, and combined age-gender groups in African American patients. MATERIALS AND METHODS: Lateral cephalometric radiographs of 160 African American patients (97 boys and 63 girls; age, 7 to 14 years) with normal occlusion and no history of orthodontic treatment were collected from the Bolton-Brush Growth Center. Cephalometric images were hand traced, and ODI and APDI values were assessed. Two-sample t tests were used to compare mean ODI and APDI values between African American and white patients; and between male and female African American patients. One-way analysis of variance, followed by the Tukey test, was used to compare mean ODI and APDI values among different African American age and combined age-gender groups. RESULTS: Mean ODI and APDI values were significantly lower (P

The objective of this study was to compare the efficacy of supportive periodontal therapy (i.e. scaling and root planning, SRP) alone, versus a chemical device silica dioxide (SiO2) colloidal solutions (SDCS) used in association with SRP in the treatment of chronic periodontitis in adult patients.
A total of 20 patients with a diagnosis of chronic periodontitis (40 localized chronic periodontitis sites) in the age group of 35 to 55 were selected. None of these patients have previously received any surgical or non-surgical periodontal therapy and demonstrated radiographic evidence of moderate bone loss. Two non-adjacent s...

Conclusion: The 3D finite element model based on 3D finite element software was highly efficient, and its numerical simulation was accurate, which was important for the subsequent biomechanical analysis of PVCR orthopaedy. In addition, the vertebral stress of PVCR orthopaedy was different in each body part, which was mainly affected by the applied orthodontic force and the sites of the orthodontic area.

Authors: Montis N, Cotti E, Noto A, Fattuoni C, Barberini L Abstract Chronic apical abscess (CAA) is a lesion of apical periodontitis mostly characterized by areas of liquefactive necrosis with disintegrating polymorphonuclear neutrophils surrounded by macrophages. Its presence leads to local bacterial infection, systemic inflammatory response, pain, and swelling. The use of a novel approach for the study of CAA, such as metabolomics, seems to be important since it has proved to be a powerful tool for biomarkers discovery which could give novel molecular insight on CAA. So, the aim of this study was to verify the p...

Authors: Costa DC, de O Silveira L, Queiroz SI, Dantas WR, Da Silva JS, Germano AR Abstract BACKGROUND: Chemical curettage has become popular in the definitive treatment of benign aggressive odontogenic lesions. Therefore, this study aims to verify the relapse rate and associated factors after the enucleation protocol, peripheral ostectomy and Carnoy's solution. METHODS: This is a retrospective sectional study with 30 patients, selected by non-probabilistic convenience sampling, submitted to the protocol from 2008 to 2018. The study was composed by the data collection phase of the medical records and clinical a...

Objective: This communication is the first assessment of outcomes after surgical repair of cochlea-facial nerve dehiscence (CFD) in a series of patients. Pre- and post-operative quantitative measurement of validated survey instruments, symptoms, diagnostic findings and anonymous video descriptions of symptoms in a cohort of 16 patients with CFD and third window syndrome (TWS) symptoms were systematically studied.Study design: Observational analytic case-control study.Setting: Quaternary referral center.Patients: Group 1 had 8 patients (5 children and 3 adults) with CFD and TWS who underwent surgical management using a prev...
