Abstract:
objective: The aim of this study was to evaluate and compare the effect of silicon based soft relining material ''Multisil-Soft '' and the acrylic based soft relining material '' COE-SOFTM ''on accumulation oral floral in lateral maxillary defect.
Materials and Methods: Type of study: Randomized clinical Trial (RCT) fourteen patients with lateral maxillectomy defect were taken the outpatient clinic, Oral and maxillofacial Prosthodontic department Faculty of Dentistry, Ain Shams university.
Grouping: Patients were randomly divided into two equal groups. Group-I: Seven patients had received Definite obturator relined with silicon based soft relining material. Group–II: patients were rehabilitated with definite obturator relined with acrylic based soft relining material. microbiological samples were taken for bacterial count and bacterial DNA load detection by Polymerase chain reaction Real-time PCR. Microbial evaluation was performed at the time of relining, three and six months after relining of the obturator.
Results: The results of this study revealed that the bacterial count was significantly greater for group II compared to group I at time of relining - 3 months and at time of relining - 6 months. On the other hand, the bacterial DNA load was significantly greater for group I compared to group II at the intervals at time of relining - 3 months and at time of relining - 6 months.
Conclusion: Within the limitations of this study; it may be concluded that: Acrylic based relining material (COE-SOFTTM) is more heavily accumulation of oral floral than silicon based relining material (Multisil-Soft).
