Microbial community alteration in tongue squamous cell carcinoma.

Tongue squamous cell carcinoma (TSCC) is the most common oral cavity malignancy. The role of the microbial community in TSCC development and progression is unclear. In the present study, 23 patients with TSCC were recruited.

The Role of Autologous Platelet Concentrates in the Treatment of Medication-Related Osteonecrosis of the Jaw.

The frequent refractory response of patients to the treatment of medication-related osteonecrosis of the jaw (MRJON) has attracted clinicians' attention to several treatments. However, they are at best, palliative, and have a higher failure rate than previous treatments. The present meta-analysis was performed to evaluate the clinical effectiveness of autologous platelet concentrates (APCs) combined with surgery in the treatment of MRONJ.

Autologous Platelet Concentrates as Clinical Substitutes for Connective Tissue Graft in the Treatment of Miller Class I and II Gingival Recessions: An Updated Meta-Analysis.

This meta-analysis aimed to evaluate the clinical effectiveness of autologous platelet concentrates (APC) + coronally advanced flap (CAF) (Group A) compared with connective tissue graft (CTG) + CAF (Group B), and CAF alone (Group C), in patients with Miller Class I or II gingival recessions. Relevant articles published before December 2018 were retrieved electronically without date or language restriction and screened according to inclusion criteria. Quantitative meta-analysis was conducted comparing the groups.

Morphology of the lumbar multifidus muscle in lumbar disc herniation at different durations and at different ages.

The aim of the present study was to evaluate the relative functional volume of bilateral lumbar multifidus (LM) muscles across different stages and ages of patients with lumbar disc herniation (LDH). The relative functional volumes of LM muscles in both non-affected and affected sides in the L4-L5 and L5-S1 segmental level were measured in a resting prone position, and visual analogue score (VAS) for pain and Japanese Orthopedic Association (JOA) scores were recorded. The correlation between changes in the relative net volume of LM muscles and times of onset, ages, VAS and JOA scores were analyzed.

[A revised scheme for LeFort classification of upper jaw fractures].

Objective: To put forward a revised scheme on LeFort classification for the upper jaw fractures.

Methods: 193 consecutive cases with the primary diagnoses of upper jaw fractures were involved in this study, for each one of which water's and CT scan were available to decide the fracture site and pattern. Data were filed in term of classification items as LeFort I, II and III fracture, as well as sagittal fracture and alveolar fracture.
