“…This amelioration was not associated with a marked reduction in the microbial counts. Other factors might have contributed to the improvement of the clinical situation by the glazing such as a reduction of the mechanical irritation or prevention of leaking of allergenic or toxic components from the acrylic resin ( Fernstrøm & Øquist, 1980a,b; Szabo, Valderhaug & Ruyter, 1985; Budtz‐Jørgensen & Kaaber, 1986).…”

It was the intention to study if glazing the fitting surface of maxillary dentures with a light-curing acrylic resin would diminish the bacterial counts. The study included the application of a photopolymerizing glaze to one half of the fitting denture surface; after 15 days microbial plaque was collected from a 1 cm2 area of the glazed and the untreated resin, respectively. At the same time bacteria were collected from a 1 cm2 area of the corresponding sites on the palatal mucosa. The application of the glaze had modified the number of bacteria cultured from the glazed surface versus the untreated surface. Denture surface: total aerobic bacteria, 1:4; aerobic streptococci, 1:4; aerobic staphylococci, 1:5; anaerobic bacteria, 1:3.5; mucosal surface aerobic bacteria, 1:4; streptococcal, 1:4. The differences were statistically significant at P<0.002. However, from a quantitative and qualitative point of view these differences were minor compared with the actual concentrations of the microorganisms of 104-106/cm2 observed on the fitting denture surface and the palatal mucosa.

“…In order to overcome this issue a number of researchers developed techniques and applied different coating materials, such as titanium dioxide, oils, monomers, or high polymerized glaze. [23][24][25][26] All of these coatings presented issues such as discoloration of the denture material, limited short-term improvement of its mechanical properties, or questionable longevity in the oral environment, preventing them from becoming established. [23][24][25][26] Parylene, the trade name of poly para-xylylene, refers to a family of polymers used as coating materials because of their unique ability to create a protective layer on various surfaces.…”

Statement of the Problem. The colonization of micro-organisms on acrylic resin dentures may result in denture-induced stomatitis. No efficient coating has yet been proposed to address this issue. Purpose. The purpose of this in vitro study was to assess the effect of various initial surface finishes and different Parylene (P) coating thicknesses on the surface roughness (Ra) and surface free energy (SFE) of Parylene coated polymethyl methacrylate (PMMA). Material and Methods. One hundred and sixty PMMA specimens were produced and divided into 8 groups as follows: Group A: uncoated-1000grit finish; group Ap1: 10 μm P coated -1000grit finish; group B: uncoated -1200grit finish; group Bp: 10 μm P coated -1200grit finish; group C: uncoated2400grit finish; group Cp: 10 μm P coated -2400grit finish; group Ap2: 20 μm P coated -1000grit finish; group Ap3: 30 μm P coated -1000grit finish. The Ra of all specimens was measured with a noncontact profilometer. To calculate the SFE, the Owens-Wendt approach was applied after measuring the contact angles with a goniometer. The topography of the specimens was observed by scanning electron microscope.

“…The effects of surface glazing treatment with tbe Perma Cure System are claimed to be 1) an enhanced surface lustre, 2) an increase of wear resistance by 90 times to that of conventional denture base resin, 3) and an increase in Knoop hardness by 1.8 times (10). In a laboratory study it was confirmed that coated denture base polymers had increased surface hardness compared with the uncoated surface, but the hardness was partially reduced after immersion of the polymer speeimens in water (16). In the present sttidy it was found that the unpolished fitting denture surface obtained a high degree of surface lustre following treatment with the Perma Cure System; however, this study was not designed to give quantitative data on changes ofthe surface lustre and hardness.…”

– Control of denture plaque accumulation is essential to obtain and maintain a healthy oral mucosa in denture wearers. The present study was designed to study the effect on denture plaque accumulation and denture stomatitis of coating the fitting denture surface by a glaze. Twenty‐one subjects wearing complete dentures participated in the study. Glazing of the denture surface was performed using a Perma Cure System. Plaque accumulation was studied clinically and using a semiquantitative microbiologic technique. Plaque accumulation on the glazed and the non‐glazed halves of the fitting denture surface was compared after 1 wk. There was significantly less plaque on the glazed half of the denture (P<0.001), and the calculated number of CFU of bacteria/cm2 was significantly lower from the test area of the glazed half than from the test area, of the non‐glazed half of the denture (P<0.001). When the patients were reexamined 1 month after the entire fitting denture surface bad been glazed plaque scores, yeast scores and number of CFU of bacteria/cm2 were not significantly different from those observed before glazing. There was a reduction of the erythema of the palatal mucosa in 14/19 patients with denture‐induced stomatitis. The study indicates that coating of the fitting denture surface by a glaze may be a means to improve denture cleanliness; however, the present glazing system should be further developed to produce a more uniform glazing.
