Proximal Caries Clinical Trial
Official title:
Long-term Bi-center Trial to Compare the Radiological Cavity Progression of Approximal Caries Following Infiltration or Standard Treatment
The aim of the planned in-vivo trial is to investigate the effectiveness of the caries
infiltration technique for the repression of caries progression.
Within the framework of this investigation it is intended that the hypothesis to be
substantiated is that carious cavities, which have been treated with the caries infiltration
technique, exhibit significantly reduced radiological progression than those cavities that
have been treated using standard preventive treatments.
In this multicenter trial, a total of 90 test subjects are included and 45 test subjects at
each institution are to be treated with both, the infiltration technique and using
conventional fluoridation treatment in different sides of the mouth ("split-mouth design").
The anticipated result of this trial shall deliver information on the long-term
effectiveness of caries infiltration to prevent the progression of existing approximal
carious lesions, and thereby enable an improvement in caries prevention within the scope of
dental treatment.

Eligibility |
Inclusion Criteria: - Age: 18 years and older - Good general health - At least 2 active, approximal caries lesions present without evidence of frank cavitation Caries depth: E2 - D1 (minimum extension to the inner half of the enamel and maximum to the outer third of the dentin) - The posterior teeth on the upper and lower arches from distal of the first premolar to mesial of the second molar will be included - All teeth to be treated must have approximal contacts with the adjacent teeth in the arch - Other teeth requiring treatment will be treated prior to the beginning of the trial - The patients must declare their consent to participate in the clinical trial following the provision of the required clarifications regarding the method, significance and scope of the trial as well as the associated risks. They may withdraw this consent at any time. - Participation in the follow-up examinations Exclusion Criteria: - - Parallel participation in a further trial relating to dental materials - The patient has not signed the participant consent form - Pregnant and breastfeeding women prior to the trial commencing A woman that becomes pregnant after the treatment has been performed will remain in the study, unless she becomes pregnant for a second time in which case, she will be excluded from the study - Unexplained diseases of the mucous membranes or conditions in the sense of contact allergies to materials used, e.g. oral lichenoid lesions - Known allergies to ingredients contained within the treatment materials used - Infectious diseases such as HIV, hepatitis, etc - Undergoing orthodontic treatment at the time of the trial - Persons who are presently taking other medication due to other illnesses, which upon our examination are deemed to possibly be a risk or a problem for the patient or the study - A large number of existing carious lesions that have not been restored and would require extensive treatment, comprehensive prosthetic restorations that need to be done or replaced and severe periodontal disease - Current use of bleaching products or use within the two weeks previous to the start of the study - No assured dry isolation possible as required per the criteria of the adhesive technology (rubber dam system) - Persons with a history of allergies - Patients with dental treatment phobias |
