Farzin M, Bahrani F, Adelpour E - J Dent (Shiraz) (2013)

Bottom Line: The subjects immersed in denture cleanser solutions and distilled water did not reveal any significant difference (p= 0.90).The effect of the denture cleansers and distilled water on the bond strength was not statistically different; however, the difference was significant between the immersed groups with the non-immersed group.Moreover, type of the denture cleanser did not show any effect on the tensile strength.

ABSTRACT

Statement of problem: One of the most clinical challenging issues in prosthodontics is debonding of soft liners from the denture base.

Purpose: The aim of this study was to evaluate and compare tensile bond strength between soft liner and heat-cured acrylic resin when immersed in two different types of denture cleanser and distilled water, at different period of times.

Materials and method: In this experimental in vivo study, 238 heat-cured acrylic blocks were made. A soft liner was embedded between the acrylic blocks. Samples were divided into four groups: 17 samples were in the control group and were not soaked in any solution .The remaining samples were divided into 3 groups (Distilled water, Calgon and Fittydent). Each group was then subdivided into two subcategories, regarding the immersion time variable; 15 and 45 minutes. All samples were placed in tension force and tensile bond strength was recorded with the testing machine. One- way ANOVA and Tucky HSD post-hoc test were adopted to analyze the yielded data (α> 0.05).

Results: Specimens which were immersed in two denture cleansers (Fittydent and Calgon) and in distilled water showed significant difference (p= 0.001) in bonding strength when compared to the control group. The subjects immersed in denture cleanser solutions and distilled water did not reveal any significant difference (p= 0.90). For all groups; most of the bonding failures (72%) were cohesive type.

Conclusion: The effect of the denture cleansers and distilled water on the bond strength was not statistically different; however, the difference was significant between the immersed groups with the non-immersed group. Moreover, type of the denture cleanser did not show any effect on the tensile strength. The tensile strength increases with time of immersion.

Mentions: When specimens were immersed in distilled water, Fitty dent and Calgon/ Clorox, the data were significantly different (p< 0.001) with time, with the highest values varying from 1.58±0.35 to 9.98±0.28 MPa (Figure 1). For all groups, most of the failures (72%) were cohesive for the studies of liner material (Table 3).
