Published: September 2018

Introduction: Nanocomposite has been developed as a dental restoration. Nano-scale filler can result in high mechanical properties and good esthetic. Nanofiller materials such as partially stabilised zirconia (PSZ) has been recommended for dental use. This form of zirconia can be stabilised by the addition of several different oxides such as magnesia and calcia. Chitosan as a coupling agent was able to increase the nanocomposite’s mechanical properties. The purpose of this research was to evaluate the nanocomposite’s hardness value with and without the addition of chitosan as a coupling agent as well as a different stabiliser of zirconia filler. Methods: Procedures of this research consisted of several stages which were the fabrication of nanocomposite and mechanical properties measurement using the Vicker’s hardness testing. Results: The nanocomposite’s hardness value (kg/mm2) with zirconia filler stabilised by MgO without the addition of chitosan was as much as 5.09 and with the addition of chitosan was 7.51; the nanocomposite ’s hardness number with zirconia filler stabilised by CaO without the addition of chitosan was 8.16 and with the addition of chitosan was 13.13. The results were then analysed statistically using the Analysis of Variance (ANOVA) test and showed a significant difference between all of those data groups. Conclusion: The addition of chitosan as well as different stabiliser (MgO and CaO) of Zirconia filler had affected the nanocomposite ’s hardness value.

Introduction: The dentist’s evaluation of complete denture often differs from the patient’s evaluation. Dentists are more prioritising the clinical aspects of the dentures, such as vertical dimension, aesthetical, stability, and denture-bearing area, while patients are more prioritising their satisfaction based on aspects such as aesthetical, mastication, comfort, and phonetic ability. The purpose of this study was to determine the relationship between the stability of maxillary and mandibular denture-bearing area towards the complete denture patient’s satisfaction level. Methods: This study was a cross-sectional study with purposive sampling as the sampling method. The sample of this study was as much as 30 complete denture patient. The patients were interviewed using a questionnaire in each of the patient’s house, to obtain a more honest patient’s satisfaction assessment on the dentures, without being affected by any clinical environment and assessment. The interview was conducted before the clinical evaluation was performed. The statistical analysis was performed using the Fisher’s test. The stability of the denture-bearing area was evaluated clinically. Mastication ability and patient’s comfort were evaluated using a questionnaire. Result: A significant relationship was found between the stability of maxillary denture-bearing area towards mastication (p = 0.012), and the stability of mandibular denture-bearing area towards mastication (p = 0.029); while no significant relationship was found between the stability of maxillary denture-bearing area towards the patient’s comfort (p = 0,051), and the stability of mandibular denture-bearing area towards the patient’s comfort (p = 0,547). Conclusion: There was a relationship between the stability of maxillary and mandibular denture-bearing area towards the patient’s masticatory satisfaction level. However, the relationship between the stability of maxillary and mandibular denture-bearing area towards the patient’s comfort was not found.
