Overview
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?
Eligibility
Inclusion Criteria:
- Children who exhibit cooperative dental behaviours (rating 3 and 4) according to Frankl's behaviour rating scale (Frankl et al. 1962)
- Presence of at least one maxillary anterior permanent tooth with one-third of crown structure loss from dental trauma
- The affected tooth must be vital or have undergone vital pulp therapy (e.g., pulpotomy with Calcium hydroxide, white-MTA, or Biodentine)
Exclusion Criteria:
- Known allergy to methacrylate-based materials
- Presence of parafunctional habits, such as bruxism
- Presence of rampant caries
- Presence of signs of hypomineralisation, such as post-eruptive breakdown, hypersensitivity, changes in enamel texture and hardness, and abnormal translucency on radiographs.
- The affected tooth is classified as having moderate or severe discolouration according to Dean's fluorosis index (Dean, 1942)
- The affected tooth has lost less than one-third of its coronal crown structure
- The affected tooth has a fracture located at the subgingival margin
- The affected tooth requires splinting due to the severity of the trauma
- Presence of severe malocclusion that could compromise the integrity of the restoration
