Overexpression of immunomodulatory mediators in oral precancerous lesions.

Human leukocyte antigen (HLA) G and E, programmed cell death 1 ligand 1 (PD-L1), IL-10 and TGF-β are proteins involved in failure of the antitumor immune response. We investigated the expression of these immunomodulatory mediators in oral precancerous lesions (oral leukoplakia-OL; n=80) and whether these molecules were related to the risk of malignant transformation. Samples of normal mucosa (n=20) and oral squamous cells carcinoma (OSCC, n=20) were included as controls.

Combined Acupuncture and Auriculotherapy in Burning Mouth Syndrome Treatment: A Preliminary Single-Arm Clinical Trial.

Background: Burning mouth syndrome (BMS) is a chronic pain disorder that is difficult to diagnose and refractory to treatment; it is more prevalent in pre- and postmenopausal women. Acupuncture and auriculotherapy have been suggested as options for the treatment of pain because they promote analgesia and allow for the reduction of symptoms with lower doses of drugs; this leads to greater patient compliance with treatment and has a positive effect on quality of life. Clinical trials investigating the effectiveness of acupuncture in the treatment of BMS are scarce in the literature.

Marginal bone level changes and implant stability after loading are not influenced by baseline microstructural bone characteristics: 1-year follow-up.

The Influence of Tactile Perception on Classification of Bone Tissue at Dental Implant Insertion.

Background: Various ways of using the Lekholm and Zarb (L&Z) classification have added to the lack of scientific evidence of the effectiveness of this clinical method in the evaluation of implant treatment.

Purpose: The study aims to assess subjective jawbone classifications in patients referred for implant treatment, using L&Z classification with and without surgeon's hand perception at implant insertion. The association between bone type classifications and quantitative parameters of primary implant stability was also assessed.

Unlabelled: Esthesioneuroblastoma is an uncommon tumour of neuroectodermal origin. The authors describe a rare presentation of an atypical esthesioneuroblastoma invading oral cavity. The clinical presentation, aetiology, diagnosis, and management of this condition are discussed.

Agreement between cone beam computed tomography images and panoramic radiographs for initial orthodontic evaluation.

Objective: The aim of this study was to compare the agreement between cone beam computed tomography (CBCT) and panoramic radiographs for initial orthodontic evaluation. This study was not meant to test differences between imaging modalities or to indicate superiority of one technique.

Study Design: Thirty-eight subjects with both panoramic and CBCT images were retrospectively collected.

Agreement between Histomorphometry and Microcomputed Tomography to Assess Bone Microarchitecture of Dental Implant Sites.

Background: Histomorphometry and microcomputed tomography (microCT) have been used in implant studies but need better understanding before being used as equivalent methods.
