About this study

Official title: Clinical Performance of Direct Anterior Composite Restorations Using Innovative Esthetic Dual-Shade Versus Polychromatic Natural Layering Technique Randomized Clinical Trial

the importance of this study is to evaluate the clinical performance of direct anterior resin composite restoration constructed using innovative esthetic dual-shade technique and another restoration constructed using polychromatic natural layering technique with various finishing and polishing steps.

The benefit from carrying out this study is to help the practitioners to decide the most suitable, easy, perfect technique to provide an optimally aesthetic, long lasting with superior clinical performance direct anterior resin composite restoration.

Read the detailed description

-Study setting: Study is to be conducted in the Conservative Dentistry Department - Cairo University.

  • Interventions:
  1. Preoperative clinical assessment: (O.S) will diagnose and select patients according to inclusion and exclusion criteria. He will record all base line data with understanding of patients' chief complains and aesthetic needs after treatment. Moreover, he will provide guidance for patients to prepare for the study.
  2. (A.H) and (G.Z) will take standard preoperative digital photographs before intervention by modifying mobile camera with smile lite (made in Switzerland) and smile capture 2016 contain 10 adaptors to allow connection between smile lite and the smartphone then photos will be saved in a computer.
  3. (A.H) and (G.Z) will take color shade using both Vita shade guide and Vita-Easy shade compact.
  4. .(A.H) and (G.Z) will ask patient for his satisfaction will be taken by visual analogue scale (0-100mm), 0 score refer to not satisfied at all, while 100 score refer to totally satisfied.
  5. (G.Z) and (A.H) will carry out all these tests at baseline, immediately after, 6 and 12 months in post-operative follow-up visits.
  6. Pre-operative planning (O.S) will be responsible for randomization according to patient selection for the sealed envelope containing which half will receive the control and the other will receive the intervention (Split mouth technique). Control group will be performed using polychromatic composite layering technique .Intervention group will be performed using dual shade composite layering technique.
  7. Intraoperative procedure: (G.Z) will do the following procedures:
  • Silicone matrix will be fabricated either directly in the patient mouth using lingual surface of the remaining tooth structure and the existing restorations as a guide ,or fabricated on a study cast after optimizing the shape and function of the teeth with a wax up.
  • Teeth preparation: after complete removal of caries a 1.5mm 75° functional- esthetic enamel bevel will prepared using 8888 diamond bur ( Brasseler, Savannah, GA, USA) on the facial surface, the lingual bevel will be 45° functional bevel, then a coarse disc (sof-lex,3M ESPE) will be used to extend the facial bevel where needed interproximally and toward the gingival third of the facial surface.
  • Cleaning the teeth surface with fluoride-free paste(Depurdent, Dr Wild AG) and water.
  • Teflon tape will placed on the adjacent teeth to prevent there being etched.

Application of each material is done according to the manufacture instructions:

  • Application of 32% phosphoric acid (Uni-Etch,Bisco,Schaumburg, IL,USA) to enamel and dentine for 15 seconds.
  • The acid etchant will then rinsed for 30 seconds, excess water will be eliminated and dental adhesive ( Adper Single Bond 2, 3M ESPE))will be applied.
  • The silicon matrix will be seated followed by application of the lingual layer of composite( Filtek Supreme Ultra Universal Restorative[3M ESPE]) to form the lingual shell and after light curing the first increment the silicone matrix and Teflon tape will be removed.

Dual-shade layering (Intervention):

Only two composite resin material shades will be used (opaque dentine composite and enamel shade composite).

Polychromatic layering (Control):

Using and mixing different composite shades, opalescents and intensives.

  • Finishing and polishing: will be performed using all grates of sof-lex discs (sof-lex,3M ESPE) , fine and Extra fine diamond burs (Brasseler), finishing strips, medium and fine rubber polishing points( Jiffy Polishers, Ultradent).
  1. Postoperative procedure:
  • Patient satisfaction: using Visual analogue scale (0-100mm), 0 score refer to not satisfied at all, while 100 score refer to totally satisfied.
  • Digital photographs using digital camera
  • Color shade using Vita Easy shade:
  • Clinical evaluation using FDI criteria: (A.H) and (G.Z) will record all result outcomes on the following duration: immediately after, 6 and 12 months in post-operative follow-up visits.

Questions about this trial

What is this clinical trial studying?

A study testing Polychromatic layering in people with Poor Aesthetics of Existing Restoration, run by Cairo University.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
