Effects of drug abuse and mental disorders on oral health: A case report.

Substance use disorders, related to mental health issues can lead to oral pathologies. The purpose of this case report was to identify the oral conditions and manifestations in a 28-year-old male narco-dependent schizophrenic who smoked tobacco and marijuana. In intra-oral clinical exploration, poor oral hygiene, excessive tartar formation and dental plaque were observed, and the diagnosis of severe chronic periodontitis was established.

Evaluation of the sealing capability and morphological fit of prefabricated dowels and fiber-reinforced composite resin: An in vitro study.

Statement Of Problem: Prefabricated dowels do not always provide intraradicular sealing in the root canal dentin, and the lack of sealing predisposes the dowel to adhesive failure and debonding. It is unclear if fiber-reinforced composite resin dowels provide better sealing.

Purpose: The purpose of this in vitro study was to evaluate the intraradicular sealing and morphological fit of prefabricated dowels and fiber-reinforced composite resin dowels in root canal dentin.

Does microwave and hydrogen peroxide disinfection reduce Candida albicans biofilm on polymethyl methacrylate denture surfaces?

Statement Of Problem: Whether the disinfection of polymethyl methacrylate (PMMA) dentures eliminates Candida albicans biofilm is unclear.

Purpose: The purpose of this in vitro study was to determine the antimicrobial effect of immersion in hydrogen peroxide (HO) and subsequent application of microwaves on the formation of C albicans biofilm on the surface of polished and unpolished PMMA disks.

Material And Methods: Polished and unpolished PMMA disks (n=40) were mounted in a Center for Disease Control (CDC) biofilm reactor by adding yeast-dextrose-peptone (YPD) broth inoculated with C albicans in a cell suspension for 24 hours.

Neoadjuvant chemotherapy in locally advanced colon cancer: a systematic review.

Background: Preoperative or neoadjuvant chemotherapy (NAC) has emerged as a novel alternative to treat locally advanced colon cancer (LACC), as in other gastrointestinal malignancies. However, evidence of its efficacy and safety has not yet been gathered in the literature. The aim of the present study was to perform an extensive review of the scientific evidence for NAC in patients with LACC.
