Randomized Controlled Trial
Clinical evaluation of coronally advanced flap with or without platelet-rich fibrin for the treatment of multiple gingival recessions.
The aim of this randomized, controlled study was to assess the clinical effect of platelet-rich fibrin (PRF) in combination with coronally advanced flap (CAF) on root coverage, esthetics, and patient satisfaction when compared to CAF alone for the treatment of multiple Miller class I recessions. ⋯ The additional use of PRF membrane did not provide additional benefits in terms of root coverage outcomes compared with CAF alone. The use of PRF membranes increased tissue thickness significantly.

The progression level of extracapsular spread (ECS) for cervical lymph node metastasis of oral squamous cell carcinoma (OSCC) was previously divided into three types, and their relationships with the prognosis of patients were re-examined. ⋯ This study indicated that the progression level and tumor budding of ECS for cervical lymph node metastasis were useful prognostic factors in OSCC patients.

Randomized Controlled Trial Comparative Study
Prospective clinical study comparing intraligamentary anesthesia and inferior alveolar nerve block for extraction of posterior mandibular teeth.
The aim of the study was to compare the efficacy of intraligamentary anesthesia (ILA) with conventional inferior alveolar nerve block (IANB) for extraction of mandibular posterior teeth. ⋯ ILA can be recommended for routine dental extractions.
