Vacterl syndrome: Medical and stomatological considerations for comprehensive patient management.

Aim: The VACTERL association or Syndrome consists of Vertebral, Anorectal, Cardiac, Tracheo-Esophageal, Renal, and Limb defects. The diagnosis relies on the presence of at least three of these structural abnormalities. This study reports a single case of a patient with VACTERL Syndrome (VS), aiming to assist dentists in recognizing the general aspects, systemic changes, and oral care related to this condition.

Myelomeningocele: Medical Considerations and Stomatologic Aspects in the Dental Treatment.

The aim was to analyze systemic and oral aspects of patients with myelomeningocele (MMC), relevant for their dental treatment. Dental treatment of these individuals requires the dentist's extensive knowledge and careful information to determine the dental treatment plan. Thirty participants aged 3 to 16 years were divided into 2 groups: study group (15 MMC individuals) and control group (15 healthy subjects).

CAD/CAM system influence marginal fit of different ceramic types?

Objective: This study aimed to evaluate the marginal fit of zirconia and lithium disilicate ceramic restorations processed by computer-aided design (CAD)/computer-aided manufacturing (CAM) system.

Materials And Methods: Ten models were prepared from a metal die, on which scanning was carried out to obtain the virtual model for the processing of zirconia and lithium disilicate ceramics using the CAD/CAM technique. Gypsum models were fabricated and used for scanning the restorations.

Role of tyrosol on Candida albicans, Candida glabrata and Streptococcus mutans biofilms developed on different surfaces.

Purpose: To assess the effect of tyrosol on the production of hydrolytic enzymes (by Candida biofilm cells) and acid (by Streptococcus mutans biofilms), as well as to quantify single and mixed biofilms of these species formed on acrylic resin (AR) and hydroxyapatite (HA).

Methods: Candida and S. mutans biofilms were formed on AR and HA in the presence of tyrosol during 48 hours.

Caries experience and salivary aspects in individuals with fragile X syndrome.

Fragile X syndrome (FXS) is the most common cause of hereditary mental retardation, but studies on the oral health condition of these patients are rare. The aim of this study was to determine the experience of dental caries in individuals with FXS, by examining the saliva profile, oral hygiene, socioeconomic characteristics and use of controlled drugs in these patients. Dental health was estimated using the decayed, missing and filled teeth index (DMF-T) and sialometry, and the pH value and buffering capacity of the saliva, colony forming units of S.

General and stomatologic aspects of bardet-biedl syndrome.

Objective: The purpose of this study is to present a clinical report of a patient with Bardet-Biedl syndrome, aiming to help the dentist to identify the general aspects, systemic changes, alterations.

Clinical Report: Bardet-Biedl syndrome is defined as a genetic disorder of autosomal recessive condition; this case is a male patient, 20 years old. The general features presented by the patient were strabismus, polydactyly, hypogonadism, obesity, cognitive impairment, and autistic behavior.

Polytetrafluoroethylene added to acrylic resin: surface properties and Candida albicans adherence.

Purpose: To evaluate the surface properties and Candida albicans adherence on two acrylic resins, one polymerized by long cycle and the other by short polymerization cycle, with added 2% PTFE (wt/wt) (experimental groups) or not added (control groups).

Methods: The specimens were divided into four groups (n = 10 per group): (1) acrylic resin polymerized by long cycle; (2) acrylic resin polymerized by long cycle with added 2% PTFE; (3) acrylic resin polymerized by short cycle; and (4) acrylic resin polymerized by short cycle with added 2% PTFE. After finishing and polishing, all specimens were assessed for their surface roughness (pm), contact angle (degree) and surface free energy (erg/cm 2) Saliva-coated specimens were submitted to the adherence assay with C.

Efficacy of denture cleansers on Candida spp. biofilm formed on polyamide and polymethyl methacrylate resins.

Statement Of Problem: Although new materials have emerged as options to fabricate removable dental prostheses, the development of Candida biofilms on these materials and the effectiveness of methods to control these pathogenic biofilms are poorly understood.

Purpose: The purpose of this study was to evaluate the efficacy of denture cleansers on Candida single- and dual-species biofilms formed on polyamide resin.

Material And Methods: Polymethyl methacrylate (PMMA) resin (Acron MC) and polyamide resin (Flexite M.

Preload loss and bacterial penetration on different implant-abutment connection systems.

Preload loss can favor the occurrence of implant-abutment interface misfit, and bacterial colonization at this interface may lead to implant failure. The aim of this study was to evaluate the preload loss and bacterial penetration through the implant-abutment interface of conical and external hexagon connection systems subjected to thermal cycling and mechanical fatigue (TM). Four different implant-abutment connection systems were evaluated (n=6): external hexagon with universal post, Morse taper with universal post, Morse taper with universal post through bolt, and locking taper with standard abutment.

Polytetrafluorethylene added to acrylic resins: mechanical properties.

The addition of different polymers, such as polytetrafluorethylene (PTFE), to denture base resins could be an option to modify acrylic resin mechanical properties. This study evaluated the surface hardness, impact and flexural strength, flexural modulus and peak load of 2 acrylic resins, one subjected to a long and another subjected to a short polymerization cycle, which were prepared with or without the addition of 2% PTFE. Four groups were formed according to the polymerization cycle and addition or not of PTFE.

Rehabilitation of maxillary edentulism with implant-supported milled-bar prostheses.

Implantology has allowed more options for rehabilitation of complete and partially edentulous patients. The professional should describe all possible alternatives to the patient, addressing all the positive and negative aspects of each possibility, such as treatment time, complexity of surgical procedures, and the final cost. The patient should select the best cost-benefit relationship because fixed prostheses are often not the option of choice for the patient.
