Long-Term Periodontal Tissue Changes Associated With Metal-Ceramic Crowns: An 8-Year Split-Mouth Study

Brief Summary

The goal of this clinical trial is to to evaluate the periodontal condition around metal-ceramic crown. The main question to be answered is: whether the metal-ceramic crown is the cause of gum changes? The study offers to involve patients who receive single metal-ceramic crown and have kept the same tooth intact on the other side of the mouth. The condition of the gums around the crown will be compared with the corresponding natural teeth on the oposite side of the mouth. Clinical parameters such as plaque accumulation, bleeding on probing, periodontal pocket depth and gingival recession will be evaluated. All procedures are part of routine dental examination. Participants: will be invited for gingival examination 3 months after receiving the metal-ceramic crown, will receive a routine hygiene instruction, will be invited for gingival re-examination after 8 years.
