“…If residual monomer is present, less monomer conversion occurs and may result in increased sorption and solubility. (27) Tables (2and 4) and Figure (2 and 3), demonstrated that there was a significant increase in water sorption and solubility with increase times for immersion (1,4, and 12 weeks) for both curing techniques, this results is agreement with Al-Nori et al, (2007) (28) who concluded that the immersion period have an effect on the water sorption and solubility ratios of the different types of heat cured acrylic resin, also agreement with Van (2002) (29) who found that the water sorption is gradual process taking many months to complete.…”

Materials and methods: Sixty specimens of vertex regular heat cured acrylic resin denture base material were used in this study, curing by two different technique, conventional curing technique and dry pressure curing technique, then immersed in distilled water for 1,4, and 12 week . The water sorption and solubility test were measured by means of mass change in the materials after water saturation and dehydration. While the color change test was measured by the samples converted to digital images on computer by using digital scanner, then the digital images were prepared with dimension 760 pixels*960 pixels for each samples by software program Adob Photoshop 9.0, by MATLAB 2010 program the image was analyzed to the basic primary co...

“…3 Resin akrilik yang direndam air selama 1 bulan mengalami ekspansi, tetapi perubahan massa yang terjadi secara klinis tidak bermakna. 4,5 Perbedaan penyimpanan berpengaruh pada gigi tiruan resin akrilik, hal ini disebabkan oleh sifat kimia dan fisik yang dimiliki resin akrilik yaitu bersifat menyerap air. Dengan perkataan lain bahwa resin akrilik dapat juga menyerap air dan udara, terutama di tempat yang lembab dengan tingkat kelembababan yang tinggi.…”

“…The presented work is developed for evaluating the physical characteristics of transverse strength as well as the porosity concerning traditional longterm cured acrylic resin with the use of novel ibre lask that has been created via the ibreglass. While, the light energy created via the laser might have four interactions with target tissue (Al-Nori et al, 2007;Pick and Miserendino, 1995). {Absorption, Transmission, Re lection and Scattering}.…”

“…In contrast, vital chromophores in the intra-oral delicate tissues were Melanin, Water, Hemoglobin and in the dental hard tissues, Hydroxyapatite and Water. Various laser wave-length values have many coef icients of absorption in terms of such primary tissue components, which will make the selection of laser procedure-dependent (Al-Nori et al, 2007;Pelagalli et al, 1997;Walsh, 2003). According to the application on many tissues, using the laser application in the dentistry might be classi ied in the following way: hard tissue application and soft tissue application (Einstein, 1917).…”

Curing stage by utilizing Water Bath (W.B.) one of the stages of making a denture, in this investigation, we assess the influence of utilizing W.B. and diode laser light of frequency (1064nm) with force 50mW on samples of heat-curing acrylic (PMMA) on transverse strength of this material. We utilized a sample with dimension (8x 0.8x0.3) cm. 40 samples utilized in this investigation, 20 illuminated by laser with deferent span time of light, and the staying 20 samples prepared by regular W.B. procedure. We estimated the samples' dimension when prepared by the two procedures. From a correlation on the influence of these two procedures on the quality of the samples by utilizing t-test, we reason that the samples that illuminated with laser become more quality and when we increment the term time (p>1), while there are no concedes between the samples that rewarded with ordinary W.B. (p>0.05). We presumed that utilizing laser be more accomplishment in improving the quality of heat-curing acrylic material that utilized for denture base.
