Background and study aims Cavity restoration refers to the dental treatment used to treat a hole in the tooth (for example, caries or injury). Matrix band systems are made up of a piece of metal or other material and are used to support and give form to the cavity restoration being used (for example, a dental filling) both when its being applied and then when its hardening in the tooth. Matrices are used to try and ensure the end result is similar in shape to that of the original tooth. The aim of this study was to compare two different types of matrix band system (circumferential matrix system and sectional matrix system) to see which is the best at duplicating the natural structure of the tooth. Who can participate? Adults (aged over 18) that need cavity restoration treatment. What does the study involve? Participants are randomly allocated to one of two groups. Those in group 1 have cavity restoration treatment using the circumference matrix band system. This is the oldest established matrix band system used in dentistry and it still widely used. Participants in group 2 have cavity restoration treatment using the much newer sectional matrix system. Both systems were assessed in terms of their ability to duplicate the natural shape and structure of the teeth immediately after treatment. What are the possible benefits and risks of participating? Benefits include the participants having dental treatment and having their cavities restored using one of the two were receiving restorations using one of the above mentioned matrix band system technique. There were no risks involved in this study. Where is the study run from? College of Dentistry, Qassim University (Saudi Arabia) When is the study starting and how long is it expected to run for? December 2014 to June 2016 Who is funding the study? Investigator initiated and funded Who is the main contact? 1. Dr Durre Sadaf (public) 2. Dr Muhammad Zubair Ahmad (scientific) [email protected]
