Analgesia and Side Effects of Codeine Phosphate Associated with Paracetamol Versus Oxycodone After the Extraction of Mandibular Third Molars: A Randomized Double-Blind Clinical Trial Using the Split-Mouth Model.

Purpose: To assess the analgesia and side effects of 10 mg oxycodone as compared to 30 mg of codeine phosphate associated with 500 mg of paracetamol after bilateral lower third molar extraction.

Reproducibility of a three-dimensional skeletal-based craniofacial orientation method for virtual surgical planning.

Inadequate craniofacial orientation of computed tomography (CT) scans can have significant implications in all three planes of space. The purpose of this study was to present the reproducibility of a 3-dimensional skeletal-based method of craniofacial orientation for virtual surgical planning. The protocol was defined by landmarks commonly used for cephalometry, and required identification of basion, nasion, right porion, and right orbitale, and navigation in all CT views (coronal, sagittal, and axial) for correction of yaw, roll, and pitch.

Cyst or Tumor? A systematic review and meta-analysis on the expression of p53 marker in Odontogenic Keratocysts.

The odontogenic keratocyst (OKC) is a potentially aggressive odontogenic lesion and there is an ongoing debate regarding its biological behavior and classification. The present systematic review aims to assess the expression of the p53 protein in the odontogenic keratocyst in comparison to the dentigerous cyst and ameloblastoma. We searched MEDLINE, Web of Science and Scopus for immunohistochemical studies reporting OKC's, dentigerous cysts and solid/multicystic ameloblastomas.

Three-Dimensional Analysis of the Skull Base of Individuals With Cleft Lip and Palate.

Aims: Identify variations of skull base measurements in individuals with dentofacial deformities associated or not with cleft lip and palate and compare the results with individuals without dentofacial deformities.

Methods And Results: The individuals were categorized into three different groups: dentofacial deformity without cleft malformation, dentofacial deformity associated with cleft lip and palate, and without facial deformity. The inclusion criteria were individuals over 18 years of age, without any intervention involving facial bones or structures of interest for the study and field of view encompassing from the glabella to the hyoid bone.

Analgesia and side effects of codeine phosphate associated with paracetamol vs. paracetamol after the extraction of mandibular third molars: a randomized double-blind clinical trial using the split-mouth model.

Purpose: To assess the analgesia and side effects of codeine phosphate associated with paracetamol (test medication) as compared to paracetamol (control medication) after the extraction of impacted mandibular third molars.

Materials And Methods: Forty-seven patients removed the right and left impacted mandibular third molars. After one surgery, patients took the test medication and after the other surgery, they took the control medication.

A systematic review on the expression of bcl-2 in the nonsyndromic odontogenic keratocyst: should it be considered a cyst or a tumor?

The purpose of this study is to find out if the biological behavior and the capacity of the odontogenic keratocyst (OKC) in maintaining pathologic cells alive are more similar to the dentigerous cyst or to the ameloblastoma by assessing bcl-2. We searched MEDLINE, Web of Science, and Scopus for immunohistochemical studies reporting OKCs, dentigerous cysts, and ameloblastomas. Risk difference between the lesions expressing bcl-2 was the effect measure and a P value < 0.

A clinical-based protocol of diagnosis of temporomandibular joint open lock and treatment with arthrocentesis.

Purpose: Arthrocentesis of the temporomandibular joint (TMJ) is a minimally invasive surgical procedure that provides good clinical results such as the improvement of jaw movements. It also helps to balance the synovial liquid viscosity and relieve TMJ pain by the washout of inflammatory components from the upper compartment. The purpose of this study is to report a case series of patients submitted to a clinical-based protocol of diagnosis of TMJ joint open lock and treatment with arthrocentesis.

Synergism between recombinant human bone morphogenetic protein 2/absorbable collagen sponge and bone substitutes favors vertical bone augmentation and the resorption rate of the biomaterials: Histomorphometric and 3D microcomputed tomography analysis.

There is no consensus about the ideal carrier for this growth factor. The aim of this study was to compare the bone augmentation, bone microarchitecture, and biodegradation rate of additional carriers to rhBMP-2/absorbable collagen sponge (ACS) in a vertical guided bone regeneration model.
