Influence of Three Different Denture Cleansers on Surface Roughness and Strength of Heat-polymerizing Resin: An In Vitro Study.

AIM: The purpose of the current study was to evaluate the impact of three different denture cleansers on the strength and surface roughness of heat-polymerizing resin. MATERIALS AND METHODS: A total of 120 resin discs (10 mm in diameter and 2 mm thick) were created using a stainless steel mold for surface roughness testing and flexural strength testing (in accordance with the American Dental Association (ADA) Specification No.12). Samples were divided into one of three groups (40 samples in each group): group I: Clanden, group II: Clinsodent, group III: Fittydent. Samples were immersed in denture-cleansing solutions for 30 minutes every day, and this process was repeated over a period of 15 days. Samples were stored in distilled water at room temperature in between the immersions. A surface analyzer was utilized to compare the surface roughness of each sample before and after immersion treatments. For recording flexural strength, each sample was subjected to three-point bending test by mounting samples on Universal testing machine. Comparing mean values between groups using one-way ANOVA and the Tukeys honest significant difference (HSD) post hoc test. A significance level of 0.05 was used for all statistical calculations Results: After 15 days, the maximum change of mean surface roughness of heat-polymerizing resin was found in Clanden denture cleanser group (2.64 ± 0.12) followed by Clinsodent group (2.26 ± 0.09) and Fittydent group (1.92 ± 0.06). After 15 days, the maximum change of mean flexural strength changes of heat-polymerizing resin was found in Clanden denture cleanser group (94.78 ± 0.14), followed by Fittydent group (98.64 ± 0.03) and Clinsodent group (99.26 ± 0.21). CONCLUSION: Within the limitation, the current study concluded that changes were observed in surface roughness and flexural strength of all heat-polymerizing resin samples after immersion in all three denture cleansers; but least surface roughness and flexural strength changes were observed with the Fittydent cleanser group and Clinsodent group, respectively. CLINICAL SIGNIFICANCE: Cleaning dentures is crucial for maintaining both the prosthesis and oral health; therefore, it is necessary to select a cleanser that is effective without negatively affecting the base resin's qualities over time.

Prosthetic Rehabilitation of a Maxillofacial Defect with Silicone Orbital Prosthesis: A Simplified Technique.

Rehabilitation of various maxillofacial defects is a time-consuming, complex, and overwhelming task requiring a patient-specific design and technique. Human face disfigurement involving loss of an eye enhances physical and emotional challenges. A wide range of various treatment modalities are being practiced over the period of time, with the recent one being use of ocular implants. Undoubtedly, an implant-supported orbital prosthesis has a superior outcome; it may not be as practical option considering the cost and availability, especially in economically constrained patients. The present case report describes a simplified technique for fabrication of an adhesive-retained silicone orbital prosthesis.

Innovative Technique for Fabrication of Forefinger Prosthesis.

Traumatic finger digit amputation may affect patient's psychology also along with a serious injury to the affected hand. Recently, advanced micro-surgical re-implantation can help save a damaged human finger that is badly injured and/or amputated. Considering its associated financial burden, a vast majority of such patients cannot afford it. For such patients, a hand/finger prosthesis may act as a blessing, boosting social performance. In the present case report, an innovative type of prosthesis finger replacement method is discussed.
