“…Several studies have shown the adverse effects of residual monomer on the mechanical and physical properties of acrylic resins, such as decreased impact strength and color instability 2, 3, 4. Moreover, residual monomer has been demonstrated to be toxic, irritating to oral mucosa, and can cause allergic reactions in oral tissue 5, 6, 7, 8. According to ISO 20795-1:2013, the maximum residual monomer content should not exceed 2.2% for heat-polymerized acrylic resin and 4.5% for autopolymerized acrylic resin 9…”

Background/purpose The residual monomer remaining in acrylic resin can cause an allergic reaction and is toxic to oral soft tissue. This study determined the effect of the duration of ultrasonic cleaning on the amount of residual methyl methacrylate monomer in one heat-polymerized acrylic resin, Meliodent, and three autopolymerized acrylic resins, Unifast Trad Ivory, Unifast Trad Pink, and Unifast III. Materials and methods Thirty-six disc-shaped specimens of each brand were prepared and randomly divided into six groups: control (no treatment), positive control, and ultrasonic treatment in 50°C water for 3 minutes, 5 minutes, 10 minutes, or 15 minutes. The residual monomer was extracted and analyzed using high performance liquid chromatography. Results There were no significant differences in the residual monomer amount in the Meliodent groups. The amounts of residual monomer in the autopolymerized acrylic resin positive control group and ultrasonic treatment groups were significantly lower than those of the control group for the Unifast Trad Ivory, Unifast Trad Pink, and Unifast III groups (P < 0.05). The amount of residual monomer was not significantly different between the ultrasonic treatment in 50°C water (3 minutes for Unifast Trad Pink and 5 minutes for Unifast Trad Ivory and Unifast III) groups and the positive control group (P > 0.05). Conclusion Ultrasonic treatment with 50°C water for 3–5 minutes for autopolymerized resin and 3 minutes for heat-polymerized acrylic resin reduced the amount of residual monomer similarly to previously recommended methods, using shorter treatment times.

“…This residual monomer acts as a plasticizer, thus resulting in deleterious effect on the mechanical properties of denture base resins 5 , 13 . In addition, residual monomer resulting from incomplete conversion of monomers into polymer has the potential to elicit irritation, inflammation and an allergic response by oral mucosa 4 .…”

Effect of a post-polymerization treatments on the flexural strength and Vickers hardness of reline and acrylic denture base resins

et al. 2007

This study evaluated the effect of water-bath and microwave post-polymerization treatments on the flexural strength and Vickers hardness of four autopolymerizing reline resins (Duraliner II-D, Kooliner-K, Tokuso Rebase Fast-TR and Ufi Gel Hard C-UGH) and one heat-polymerized acrylic resin (Lucitone 550-L), processed using two polymerization cycles (short cycle - 90 minutes at 73°C and 100°C for 30 minutes; and long cycle - 9 hours at 71°C). For each material, thirty specimens (64 x 10 x 3.3 mm) were made and divided into 3 groups (n=10). Specimens were tested after: processing (control group); water-bath at 55°C for 10 minutes (reline materials) or 60 minutes (L); and microwave irradiation. Flexural strength tests were performed at a crosshead speed of 5 mm/min using a three-point bending device with a span of 50 mm. The flexural strengths values were calculated in MPa. One fragment of each specimen was submitted to Vickers hardness test. Data were analyzed by 2-way ANOVA followed by Tukey's HSD test (α=0.05). L microwaved specimens (short cycle) exhibited significantly higher flexural strength means than its respective control group (p<0.05). Water-bath promoted a significant increase (p<0.05) in flexural strength of K and L (long cycle). The hardness of the tested materials was not influenced by the post-polymerization treatments. Post-polymerization treatments could be used to improve the flexural strength of some materials tested.

“…Authors reported that this could be due to the use of Erythrosine in the denture material, but was not completely clear from the study. [ 3 ] The present case report emphasizes antigenic potential of coloring agents used in various preparations and suggests that these should be used carefully as topical agent in the treatment of oral diseases. Furthermore, it highlights the fact that contact stomatitis should be taken into account in the differential diagnosis of the oral lesions.…”

Herbal oral gel induced contact stomatitis along with desquamative gingivitis due to a coloring agent

Report of a rare case of contact stomatitis manifesting as irregular erosions partially covered with pseudomembrane along with desquamative gingivitis in a 32-year-old female patient is presented. The patient was otherwise healthy and not taking any medication. She gave the history of using curcumin-based oral gel 2 days back. Allergy test to curcumin oral gel was found to be positive, which on detailed allergy testing proved to be the coloring agent, erythrosine present in the gel. Contrary to the popular belief some folk medicine preparations can lead to unwanted side effects due to the antigenic potential of ingredients present in them. In addition, every clinician, during differential diagnosis of oral lesions must bear in mind unwanted reactions to any local ointment.
