About this trial

This is an interventional treatment trial for Caries focused on measuring Caries, Cavity, Silver Diamine Fluoride (SDF), HOMINGS

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Generally healthy adult participants 18 years of age and older.
  • At least one tooth with active (soft) cavitated lesions of ICDAS score 5 or 6 near the gingival margin (coronal cervical caries at the CEJ or exposed root surfaces with soft active carious lesions exposing dentin).

Exclusion Criteria:

  • Adult participants who suffer from serious life-threatening medical diseases that interfere with basic daily self care activities.
  • Patients taking antibiotics within the last two weeks.
  • Patients using chlorhexidine or fluoride mouth washes within the last two weeks.
  • Pregnant or breastfeeding women.
  • Teeth with arrested (hard) cervical or root caries lesions.
  • Teeth that have been diagnosed with an abscess or an irreversible pulpitis, or are mobile.

Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Silver Diamine Fluoride (SDF)

Arm Description

Application of Silver Diamine Fluoride (SDF) to root or cervical carious lesions (cavities). Collection of plaque pre- and one month post-SDF application.

Outcomes

Primary Outcome Measures

Change in Bacterial Composition Before and One Month After SDF Application to Root or Cervical Caries Lesions
Using human oral microbiome identification using next-generation sequencing (HOMINGS), change in the total bacterial composition of all subjects was measured by the difference of the number of bacteria count from baseline to one month after SDF application.
Caries Arrest of Teeth Measured by Change in Dentin Texture (Soft, Hard)
Caries were examined for hardness or softness before and after SDF application. The change in the texture was examined after one month of SDF application the change from soft to hard is noted below.

Secondary Outcome Measures

Patient Assessment of Appearance of Treated Tooth (Concern With the Appearance of Study Tooth, Desire for the Study Tooth to be Filled)
Each subject was asked if they were concerned with the appearance of the tooth that SDF was applied too. They were also asked if they wanted the study tooth to be filled with a tooth color filling.

5. Study Description

Brief Summary
The study will compare bacteria levels in cavities before and after silver diamine fluoride (SDF) treatment.
Detailed Description
To assess the effect of silver diamine fluoride (SDF) treatment on microorganisms present in root caries or cervical lesions by collecting microbial deposits before and 1 month after SDF application. Bacterial samples will be collected from 20 adult subjects at the initial visit before application of SDF and one month after. At the 1 month recall, examination for caries arrest will be performed. All 40 bacterial samples will be sent to the Forsyth Institute to verify bacterial composition using HOMINGS technology.

Arm Title
Silver Diamine Fluoride (SDF)
Arm Type
Experimental
Arm Description
Application of Silver Diamine Fluoride (SDF) to root or cervical carious lesions (cavities). Collection of plaque pre- and one month post-SDF application.
Intervention Type
Device
Intervention Name(s)
Silver Diamine Fluoride (SDF)
Other Intervention Name(s)
Silver Dental Arrest
Intervention Description
No caries removal will take place. Bacterial samples will be collected using Gracey curettes at the initial visit before application of SDF and one month after. The tooth will be dried and SDF will be placed on the carious dentin until saturated. Excess will be blotted dry with a cotton pellet
