Overview
Brief Summary
Hypomineralised primary second molars are primary molars with a developmental disorder of the enamel. Preformed metal crowns already have good results for the treatment of caries on primary molars. In this study the aim is to investigate the clinical success and overall survival of preformed metal crowns as a treatment for hypomineralised primary molars. The crowns were placed using the Hall technique which is a simplified way of placing these crowns.

Outcomes
Primary Outcomes
The clinical success of preformed metal crowns using Hall technique on hypomineralised second primary molars based on clinical acceptable results.
Time Frame: 1-2 year
The results are clinical acceptable when there are no clinical signs of infection of the tooth, no caries development or heavy bleeding of the gingiva (after probing).
The overall survival rate of preformed metal crowns using Hall technique on hypomineralised second primary molars is defined as acceptable radiographical outcomes.
Time Frame: 1-2 year
The outcomes are radiographical acceptable when no signs of infection or interproximal bone loss are seen on the radiographs.
The overall survival rate of preformed metal crowns using Hall technique on hypomineralised second primary molars is defined as acceptable clinical outcomes.
Time Frame: 1-2 year
The outcomes are clinically acceptable when there are no signs of infection (abscess) or caries.
Secondary Outcomes
- The results can be affected by bruxism. Signs of bruxism will not mean failure. We will rate the wear as acceptable or successful. This bruxism will be measured by clinical signs of wear on the crowns.(1-2 year)
- The oral hygiene of the patient will be measured using the Simplified Oral Hygiene Index. The minimum value is 0: clean. The maximum value is 3: tooth surface covered with >2/3 soft dental plaque. The higher the score, the worse the outcome.(1-2 year)
