all patients will submit an unstimulated salivary sample of 1ml will in sealed test tube * then the patients will receive probiotics for 14 days . * after 14 days and another salivary sample will be collected
After assigning the patients , all patients will submit an unstimulated salivary sample of 1ml will in sealed test tubes then stored in a deep freezer until microbiological evaluation, then they'll receive an oral prophylaxis session. * The patients will receive probiotics for 14 days given to them in a sealed box. * All patients will be followed up after 14 days and another salivary sample will be collected and sent for microbiological assessment.
