Streptococcus Mutans Clinical Trial
Official title:
Efficacy of Sage Extract or Chlorohexidine Mouthwashes on Streptococcus Mutans Pathogenicity by Real-time Polymerase Chain Reaction (PCR) in High Caries Risk Patients : A Randomized Clinical Trial
In patients with high caries risk, will the use of sage extract or chlorohexidine based mouthwashes have an effect on the percentage recovery of Streptococcus Mutans (SM) and its pathogenicity detected by Real-Time Polymerase Chain Reaction (PCR) over one month follow up
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. ;
