Detailed Description
The clinical study will be held in the clinic of conservative department, Faculty of Dentistry, Cairo University. The operator in charge will be Dina Fayez Diab. Patients will be examined and selected according to inclusion and exclusion criteria, the purpose and method of the study will be explained to the selected patients for participation in the study. In the first visit , ADA caries risk assessment model will be done. Participants will be divided in to two groups according to the tested mouthwashes.
All patients will be instructed not to have a breakfast and to refrain any oral hygiene measures on the day of sample collection to avoid the influence of food consumption and contamination on the composition of saliva. The patient will sit in an erect position on the dental chair and will be given paraffin block to chew. The stimulated saliva will be collected after 2 minutes of paraffin chewing in sterile container held near the mouth. The containers will be properly labelled.
This study will be carried over one month , the saliva samples for each patients will be collected on the first dental visit. These samples will be sent to the laboratory for microbiological assessment. Patients will be provided with mouthwashes according to the tested groups and will be instructed to use it 2 times per day for 1 minute each time and no eating or drinking allowed for at least 30 minutes post rinsing. Each patient will be given the same instructions with respect to oral hygiene measures. They will be advised to continue on the same diet and will be instructed not to change their dietary habits.
Patients will come after 2 weeks for salivary samples collection and samples will be sent to laboratory for microbiological assessment. After completing the treatment for another 2 weeks , patients will come for the last dental visit to collect salivary samples which will be sent to laboratory for microbiological assessment.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Total bacterial count
Time Frame: 1 month
|
Quantitative plating ( standard plate count or SPC) will be used to determine the number of bacteria in a culture sample.
SPC reveals information on viable organisms only, bacteria colonies that are seen in the plates after incubation represent only the living organisms, not dead ones
|
1 month
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Bacterial identification
Time Frame: 1 month
|
Total extraction of DNA: Total plasmid DNA will be prepared.
The solution will be centrifuged and then left at room temperature for few minutes for the phase separation.
The aqueous phase containing DNA will be transferred to clean eppendorf Real-Time Polymerase Chain Reaction: the PCR will be done in 20 ul reaction volume containing : DNA template, enzymes primer and nuclease- free water.
The tubes containing the PCR mixture will be transferred to the cycler apparatus.
The PCR products will be analyzed in agarose gel by electrophoresis, photographed and analyzed

1 month
|
Total protein profile
Time Frame: 1 month
|
Proteins can be separated according to their molecular weight by Sodium dodecyl sulphate poly acrylamide gel electrophoresis (SDS-PAGE)
|
1 month
