Oral health-related quality of life in US adults with type 2 diabetes.

Objectives: The objective of this study was to analyze factors associated with oral health-related quality of life (OHRQoL) between type 2 diabetes mellitus (T2DM) and nondiabetic US adults.

Methods: The study sample included 2945 participants (aged ≥20) selected from National Health and Nutrition Examination Survey (NHANES) 2003-2004 that represented 130,689,262 million persons in a probability weighted sample. Oral health outcomes were measured by the NHANES version of Oral Health Impact Profile (OHIP) for OHRQoL and summarized as additive scores (OHIP-ADD) and as prevalence of negative impacts (OHIP-SC).

Dynamic mechanical thermal analysis of maxillofacial prosthetic elastomers: the effect of different disinfecting aging procedures.

In this study, dynamic mechanical thermal analysis was used to evaluate the changes that occurred in maxillofacial elastomers subjected to different disinfecting regimens. A commercial polydimethyl siloxane (PDMS) and an experimental chlorinated polyethylene (CPE) were treated with different disinfection procedures for a period that simulates 1 year of clinical service: microwave exposure (D1), hypochlorite solution (D2), neutral soap (D3), and a commercial disinfecting solution (D4). A fifth group was kept in dark storage as control.

Tensile and microindentation properties of maxillofacial elastomers after different disinfecting procedures.

Statement Of Problem: Daily disinfection of maxillofacial prosthesis may reduce their service-life and lead to replacement.

Purpose: The purpose of this study was to evaluate possible alterations in the mechanical behavior of two maxillofacial elastomers after application of four different disinfection procedures.

Material And Methods: The materials tested were two maxillofacial elastomers, a commercially available polydimethylsiloxane (PDMS) and an experimental chlorinated polyethylene (CPE).

Effect of different disinfecting procedures on the hardness and color stability of two maxillofacial elastomers over time.

Objective: Disinfection procedures often cause deterioration in a maxillofacial prosthesis. Color and hardness alterations could lead to a replacement of the prosthesis.

Material And Methods: An experimental chlorinated polyethylene (CPE) and a commercial polydimethyl siloxane (PDMS) sample were treated with four different disinfection procedures for a period which simulates 1 year of clinical service.

The Toronto outcome measure for craniofacial prosthetics: reliability and validity of a condition-specific quality-of-life instrument.

Purpose: The purpose of this study was to refine the Toronto Outcome Measure for Craniofacial Prosthetics (TOMCP), present evidence for its reliability and validity, and use the instrument to explore differences in quality of life between prostheses made with chlorinated polyethylene (CPE) (experimental) and silicone (control).

Materials And Methods: As part of a multicenter prospective controlled randomized double-blind single-crossover clinical trial of the two materials, the TOMCP was administered at the start and end of two 4-month study arms, during which 42 patients wore prostheses made from one material then the other. Reliability was assessed at the crossover.

Effects of outdoor weathering on facial prosthetic elastomers.

Physical weathering is usually responsible for the degradation of maxillofacial prosthetic elastomers and the replacement of prostheses. The purpose of this study was to investigate the effects of outdoor weathering on the physical properties of four nonpigmented facial prosthetics after 1 year of exposure. In addition, simple mathematical models were developed to correlate the measured properties with irradiation time, including parameters with physical meaning.

Simulated microbe removal around finger rings using different hand sanitation methods.

Aim: It is our opinion that the CDC and the WHO have underestimated cross-contamination under examination gloves in dental clinics while wearing jewelry, such as finger rings. These agencies only "recommend" removing jewelry, and only washing hands for 15 seconds with soap and warm water before donning gloves. This study examined several washing procedures and finger rings using simulated microbes.

Clinical trial of chlorinated polyethylene for facial prosthetics.

Purpose: Extraoral maxillofacial prostheses have been fabricated with silicone elastomer for 50 years with few improvements. The objective of this controlled, randomized, prospective, double-blind, single-crossover, multicenter, phase III clinical trial was to determine the noninferiority of chlorinated polyethylene elastomer (CPE) to silicone elastomer for fabricating prostheses.

Materials And Methods: Forty-two patients were randomly assigned to wear a custom-made prosthesis fabricated from both materials for 4 months and asked to rate their satisfaction (0 = not satisfied, 10 = completely satisfied).

Material properties of a maxillofacial chlorinated polyethylene elastomer stored in simulated skin secretions.

Statement Of Problem: Facial prostheses deteriorate in a service environment primary due to exposition to various environmental factors, including sebaceous oils (sebum) and perspiration.

Purpose: This study investigated the physical properties of an experimental, facial prosthetic after immersion for 6 months in simulated sebum, and perspiration at 37 degrees C.

Material And Methods: Chlorinated polyethylene (CPE) specimens were immersed in simulated perspiration as well as in sebum.

Adhesive retention of silicone and chlorinated polyethylene for maxillofacial prostheses.

Statement Of Problem: A key factor of a successful facial prosthesis is the retention of the prosthesis to the patient's skin, especially when there is no mechanical means and the retention depends primarily on medical skin adhesives. Studies determining which medical adhesives provide the best bond strength for maxillofacial prostheses are needed.

Purpose: The purpose of this study was to quantify the force required to detach strips of Silastic Adhesive A/MDX4-4,210 silicone elastomer with a urethane liner (A/M-U) and experimental chlorinated polyethylene elastomer (CPE) from the skin of human subjects coated with a protective dressing using 1 of 2 medical adhesives.

Facial prosthetic rehabilitation: preprosthetic surgical techniques and biomaterials.

Purpose Of Review: Attention to detail ensuring a successful facial prosthetic rehabilitation must be considered a priority at the time of presurgery, surgery, and at every stage in fabricating the prosthesis. Teamwork between the surgeon and maxillofacial prosthodontist will ensure an optimal surgical preparation and definitive prosthesis.

Recent Findings: Evidence of interaction between team members can most certainly be encouraging to the patient.

The influence of water storage on durometer hardness of 5 soft denture liners over time.

Purpose: This laboratory study investigated the influence of water storage on the durometer hardness of 2 RTV and 3 HTV soft denture liners over a 1-year period.

Materials And Methods: Five soft denture liners were used: 2 HTV silicone rubber (Luci-Sof and Molloplast-B), 1 RTV silicone rubber (Tokuyama), 1 HTV polyphosphazene (Novus), and an RTV plasticized acrylic (PermaSoft) that uses a surface sealer. They were processed following manufacturers' instructions, cured, and stored in tap water at 37 degrees C.

Effect of multi-adhesive layering on retention of extraoral maxillofacial silicone prostheses in vivo.

Statement Of Problem: Loss of retention of maxillofacial prostheses often makes the margin visible or the prosthesis dislodge. Using several medical adhesives in combination may improve retention.

Purpose: The purpose of this study was to investigate the effect of single- and multi-adhesive layering of 2 adhesives on the retention of maxillofacial silicone elastomer strips adhered to the skin of human forearms using a peel test.

Use of primates for wear testing of dental restorative materials.

The mechanical loss of substance, both of teeth and man-made materials used to fill or replace teeth, principally occurs by attrition (the grinding of one tooth against another) or abrasion due to coarse particles present in the diet, dentifrices, or as products of the grinding itself. Nonhuman primates often have pronounced grinding or bruxing habits that serve to sharpen the teeth. Papio anubis baboons were used as a model to study the ability of teeth and restorative materials to withstand continual two- or three-body wear.
