NCT02098304

Brief Summary

This is a prospective, multi-centre, post-approval clinical study to assess the safety and the performance of the Calcivis Caries Activity Imaging System in aiding the identification of active caries lesions on the occlusal surfaces of human teeth. Following the identification of potential caries lesions by oral examination under ICDAS (International Caries Detection and Assessment System) guidelines, a disclosing solution will be applied which will cause areas of active demineralization (loss of calcium ions) to luminesce - these will be captured with an intra-oral camera to produce mapping images of the tooth surface. For the purposes of this study the presence / absence of luminescence will be used as an indicator of lesion activity / inactivity. The study will be deemed a success if the level of agreement between elevated luminescence with the Calcivis System, and areas of expected lesion activity as rated by the Investigators ICDAS staging, is above 70%, is not due to chance and correlates well with published data on active non-cavitated lesions in molars at various stages of eruption.

Outcome Measures

Primary Outcomes (2)

  • Percentage Agreement of Sound/Unsound Teeth Between ICDAS Score and Calcivis System

    % agreement calculated as no. of teeth where ICDAS assessment \& Calcivis System assessment is in agreement/total number of teeth assessed multiplied by 100. Agreement defined as a sound tooth without luminescence \& an unsound tooth with luminescence.

    Day 0

  • Measure Safety of the Calcivis Caries Imaging System

    Collection of all adverse events recorded and reported throughout the duration of the study

    Day 0 and Day 7

Secondary Outcomes (2)

  • Patient Experience

    Day 0

  • User Experience

    0 day

Study Arms (1)

Sound and Unsound Molars

OTHER

Imaging of unrestored sound molars (ICDAS 0), and third Molars (ICDAS 1,2 or 3) with the Calcivis Caries Activity Imaging System

Device: Calcivis Caries Activity Imaging System

Interventions

Teeth imaged with the Calcivis Caries Activity Imaging System

Sound and Unsound Molars

Eligibility Criteria

Age16 Years - 25 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • Patient must be 16 to 25 years old
  • Patient must have at least one unrestored molar identified as sound according to the ICDAS coding system
  • Patient must have at least one unrestored erupting (in which case occlusal surface must be such that, apart from minimal presence of an operculum over the distal marginal ridge, it is clear of the gingivae (gum)) or erupted third molar with a caries lesion identified, coded 1, 2 or 3 (according to the ICDAS coding system)
  • Patient must be willing and able to give written informed consent
  • Patient must be willing and able to adhere to study schedule

You may not qualify if:

  • Recent tooth bleaching (within previous two weeks of imaging with the Calcivis System)
  • On-going re-mineralisation treatment including, but not limited to high concentration prescription fluoride toothpaste
  • Any patient with a fixed orthodontic appliance
  • Any patient currently taking part in a clinical research study, or has taken part in a clinical research study in the previous three months
  • Pregnant and / or nursing mothers

Limitations and Caveats

All 42 patients recruited to the study are included in the Safety Population, however only 31 patients were included in the Agreement Population as one or more of the images from the Calcivis System were deemed ineligible by independent review.
