Association between serum zinc levels and recurrent aphthous stomatitis: a meta-analysis with trial sequential analysis.

Objectives: The present meta-analysis sought to investigate the potential association between zinc levels and recurrent aphthous stomatitis (RAS).

Methods: A comprehensive search of online databases (PubMed, Scopus, Web of Science, and China National Knowledge Infrastructure (CNKI)) was conducted to identify all English and Chinese studies published up to August 2020. All case-control studies that assessed plasma/serum zinc levels were eligible for inclusion.

Management of cracked tooth using simvastatin as intracanal medicament.

Cracked tooth syndrome is presented as pain associated with biting and sensitivity. Intracanal medication with simvastatin stimulates hard tissue formation at crack line, and the tooth was functioning on the follow-ups.

Orofacial manifestations of COVID-19: a brief review of the published literature.

Coronavirus disease 2019 (COVID-19) has spread exponentially across the world. The typical manifestations of COVID-19 include fever, dry cough, headache and fatigue. However, atypical presentations of COVID-19 are being increasingly reported.

Histologic Evaluation of Artificial Floors Under MTA and Nano-Filled Resin-Modified Glass Ionomer Used to Repair Furcation Perforations in Dogs.

Objective: This study aimed to compare the tissue reaction of two repair materials for furcation perforations, nano-filled resin modified glass ionomer (Nano-FRMGI) and mineral trioxide aggregate (MTA), used with or without an artificial floor.

Methods: A total of 96 teeth in 6 dogs were used for this study. After access cavities, root canals were prepared and obturated with gutta percha using cold lateral condensation technique.

N-acetylcysteine versus chlorhexidine in treatment of aphthous ulcers: a preliminary clinical trial.

Introduction: This study sought to assess the efficacy of N-acetyl cysteine (NAC) in the treatment of recurrent aphthous stomatitis (RAS).

Methods: Fifty-eight patients, aged 28 ± 9.7 years, presented with clinically diagnosed RAS to two oral medicine centers.

Subgingival microbiome of experimental gingivitis: shifts associated with the use of chlorhexidine and -acetyl cysteine mouthwashes.

This study aimed to demonstrate subgingival microbial changes associated with development, prevention, and treatment of experimental gingivitis using chlorhexidine (CHX) and -acetylcysteine (NAC) mouthwashes. This randomized clinical trial comprised two parts: a 3-week prevention sub-study in which 30 study subjects were equally assigned to either mouthwash or placebo while developing experimental gingivitis; followed by a 2-week treatment sub-study in which 20 subjects with experimental gingivitis were assigned to either mouthwash. Subgingival samples were collected at the beginning and end of each sub-study for microbial profiling with gene sequencing.

N-acetyl cysteine versus chlorhexidine mouthwashes in prevention and treatment of experimental gingivitis: a randomized, triple-blind, placebo-controlled clinical trial.

Objectives: To compare the efficacy of N-acetyl cysteine (NAC) mouthwash with chlorhexidine (CHX) in prevention and treatment of experimental gingivitis MATERIALS AND METHODS: Sixty subjects were assigned randomly and blindly into one of three equal groups: NAC, CHX, or placebo group. The study was conducted in two stages: preventive and treatment substudies. Professional prophylaxis was performed ahead of starting the preventive substudy.
