Colour Match, Stability, and Patient's Satisfaction of Single-Shade Composites in Anterior Teeth

The goal of this observational study is to evaluate the clinical performance of a single-shade composite resin, used with an injection moulding technique, in restoring maxillary incisors affected by traumatic dental injury in patients aged 6-15 years. The main questions it aims to answer are: * How well does a single composite resin colour match the natural tooth? * How stable is the colour over a 6- and 12-month follow-up? * How satisfied are the children and parents with the restoration?
