Brief Summary:

This is a prospective, single-centre clinical study to monitor caries lesion activity in orthodontic patients with the Calcivis System over a 12 week period. Dentists will identify patients who have had dental appliances in place for a minimum of 12 months and have visible white spot lesions on the anterior surfaces of incisors and / or canines at de-bond. Following de-bond, images of the tooth surface will be taken with the Calcivis System. Presence or absence of elevated luminescence on the images will indicate activity / inactivity. Only patients with at least one tooth identified as active with the Calcivis System will continue in the study and be followed up at 2, 4, 8 and 12 weeks de-bond. Images of the active teeth will be taken with the Calcivis System as before, at each follow-up visit.

The percentage of teeth showing luminescence using the Calcivis System will be calculated and summarised for all subjects for each post-baseline visit, and additionally by Investigator and ICDAS score at Visit 1. For each subject the percentage of teeth with each ICDAS score will be calculated. This will then be summarised over all subjects for each post-baseline visit and the ICDAS score will also be cross-tabulated with the presence/absence of luminescence from individual teeth for each visit.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 45 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Other
Official Title: Monitoring of Caries Lesion Activity in Orthodontic Patients With the Calcivis System
Actual Study Start Date : February 15, 2017
Estimated Primary Completion Date : June 26, 2018
Estimated Study Completion Date : June 26, 2018

Arm Intervention/treatment
Active post-othodontic lesions
Imaging with the Calcivis System
Device: Calcivis System
Following de-bond, and identification of active post-orthodontic white spot lesions at baseline with the Calcivis System, each active tooth will be again be imaged at 2, 4, 8 and 12 weeks. The images of the teeth are taken immediately before and after application of a small amount of disclosing solution. The images of each tooth are overlaid and a resulting demineralization map of the tooth produced, indicating areas of elevated bioluminescence corresponding to free calcium ions on the surface of the tooth (active caries)
Other Name: Calcivis Caries Activity Imaging System

Primary Outcome Measures :
  1. Assessment of the Calcivis System for monitoring the activity levels of post orthodontic white spot lesions [ Time Frame: 0, 2, 4, 8 and 12 weeks ]
    Measured by the visible presence or absence of elevated bioluminescence on the tooth surface over a 12 week period post de-bond

Secondary Outcome Measures :
  1. Safety of Calcivis System [ Time Frame: 0 days, 2, 4, 8 and 12 weeks ]
    Collection of all adverse events throughout study duration

  2. Assessment of the value of the feedback / communication between patient and orthodontist, after using the Calcivis system [ Time Frame: 0 days and 12 weeks ]
    Measured by Patient and User Questionnaires
