Brief Summary:

Specific Aims

1) Assess CG (Cariogenic) Saliva-Check Mutans® saliva testing for identification of high caries risk patients


Condition or disease Intervention/treatment Phase
Dental Caries Device: GC Strep Mutans Saliva Sampling Not Applicable

  Show Detailed Description

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 0 participants
Intervention Model: Single Group Assignment
Intervention Model Description: Children will have a saliva sample analyzed for amount of bacteria. Children who have higher bacteria counts are at higher risk of developing cavities.
Masking: None (Open Label)
Masking Description: Provider and investigator will know if child has clinical caries or not at the time of saliva sample.
Primary Purpose: Diagnostic
Official Title: Microbial Testing for Caries Risk Assessment
Actual Study Start Date : February 1, 2018
Actual Primary Completion Date : July 1, 2018
Actual Study Completion Date : July 1, 2018

Arm Intervention/treatment
Child with full primary dentition
All children who match inclusion criteria are eligible to have a saliva sample obtained which will act as a proxy for bacterial levels. High bacteria levels are correlated with a higher risk of developing cavities.
Device: GC Strep Mutans Saliva Sampling
Children who match inclusion criteria will have a saliva sample obtained which will act as a proxy for bacterial levels.




Primary Outcome Measures :
  1. Count of Strep Mutans bacterial [ Time Frame: 4 weeks ]
    Bacterial (MS) samples resulting in〖5x10〗^5 colony-forming units per milliliter of saliva (CFU/mL) indicates a low caries risk. In contrast, >〖5x10〗^5 CFU/mL of MS in a saliva sample correlates to a moderate or high caries risk. This study is designed to use saliva sampling to determine a non-surgical adjunctive therapy to help lower cavity causing bacteria.


Secondary Outcome Measures :
  1. Plaque Index [ Time Frame: 4 weeks ]
    An index for estimating the status of oral hygiene by measuring dental plaque that occurs in the areas adjacent to the gingival margin. A score of 0 to 3 (0=no plaque, 1=minimal plaque, 2 = moderate plaque, 3= extensive plaque is assigned to each of 5 division on the tooth). The score is then divided by 5. The patient's resultant plaque rating is considered excellent if the score is 0, Good if it is between 0.1-1.7, Fair if it is between 1.8-3.4 and Poor if it is between 3.5-5. The hope is to see a reduction of plaque score in study participants at the follow-up visit 4 weeks later.
