Microbiological Study on Maxillary Complete Dentures of Two Different Materials

October 28, 2016 updated by: mohamed mabrouk abd Elmawla mahmoud, Cairo University

Microbiological Comparative Study Between Single Maxillary Denture Fabricated From Rapid Heat Cured Resin and Conventional Acrylic Resin Modified by Titanium Dioxide Nanoparticles

Cross over design the investigator divide participants to two groups group (A) will receive rapid heat cured denture base material and group (b) will receive the acrylic denture modified by titanium dioxide nanoparticles and after washout period alternatively group (a) will receive the acrylic denture modified by titanium dioxide nanoparticles AND group (b) will receive rapid heat cured denture base material the investigator will take swaps from dentures to count the anaerobic bacteria.

Detailed Description

First the investigator will take primary impression, and pour it obtain primary cast, then will fabricate special tray an take secondary impression and obtain master cast after that duplication of master cast will be done the investigator will make cross over design.and divide participants to two groups group (A) will receive rapid heat cured denture base material and group (b) will receive the acrylic denture modified by titanium dioxide nanoparticle and after washout period alternatively group (a) will receive the acrylic denture modified by titanium dioxide nanoparticle AND group (b) will receive rapid heat cured denture base material the investigator will take swaps from the different dentures to count the anaerobic bacteria by (CFU).

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: patients take titanium dioxide denture
patients will receive titanium dioxide denture (made from conventional acrylic resin modified by titanium dioxide nanoparticles ) for 1 month in the initial phase of the trial then in the later phase after one month they will receive( rapid heat cured acrylic resin)denture
Other: titanium dioxide denture
patients will receive titanium dioxide denture (made from acrylic resin with titanium dioxide nanoparticles ) for 1 month in the initial phase then in the second phase after one month they will receive( rapid heat cured acrylic resin)denture according to the principle of crossover design
Other: rapid heat denture
patients will receive rapid heat denture for 1 month in the initial phase of the trial then in the later phase patients will receive titanium dioxide denture (made from conventional acrylic resin modified by titanium dioxide nanoparticles ) according to the principle of crossover design
Placebo Comparator: patients take rapid heat denture
patients will receive rapid heat denture for 1 month in the initial phase of the trial then in the later phase patients will receive titanium dioxide denture (made from conventional acrylic resin modified by titanium dioxide nanoparticles )
Other: titanium dioxide denture
patients will receive titanium dioxide denture (made from acrylic resin with titanium dioxide nanoparticles ) for 1 month in the initial phase then in the second phase after one month they will receive( rapid heat cured acrylic resin)denture according to the principle of crossover design
Other: rapid heat denture
patients will receive rapid heat denture for 1 month in the initial phase of the trial then in the later phase patients will receive titanium dioxide denture (made from conventional acrylic resin modified by titanium dioxide nanoparticles ) according to the principle of crossover design
