Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients should be 18 years and older.
  • Study teeth should have an interproximal (Class II) carious lesion or an existing defective class II restoration requiring restorative therapy on premolars or molars.
  • The maximum cavity depth determined by the radiograph will be D2 (Tyas classification).
  • The teeth included in the study need to have a proximal contact with the adjacent tooth and be in occlusion with the opposing dentition.
  • The teeth included in the study should be vital with no signs of pulpal pathology.
  • Patients that report brushing regularly without severe gingival inflammation and/or extensive caries.
  • Patients should have no allergies or systemic diseases which inhibit the treatment.
  • Patients should have voluntary participation and sign a written informed consent form.
  • Patients should be willing to participate in the recall/re-examination appointments.

You may not qualify if:

  • Simultaneous participation in another study about dental restorative materials.
  • Written informed consent form not signed.
  • Nonvital pulp / periapical lesion.
  • Insufficient oral hygiene despite detailed instructions.
  • Pregnancy/ breast feeding before placement of the study restoration.
  • Minors.
  • Severe malocclusion/ malalignment/ traumatic occlusion/ bruxism.
  • Known allergy to any components present in any of the materials that are used for this study.
  • Unclear mucosal alterations, e.g. oral lichenoid reactions/lesions.
  • Severe medical complications (organ transplants, cancer, immune-compromised, long-term antibiotic or steroid therapy).
  • Infectious diseases such as HIV/Aids, Hepatitis, etc.
  • Application of bleaching products less than 14 days before placement of the restoration.
  • Orthodontic treatment during the study.
  • Xerostomia.
  • Untreated periodontal diseases.
  • +6 more criteria
