Ungraded means an effect was reported without a GRADE rating; it is not a gap. No studies means the review found nothing to answer the question. The six categories are a display order, not a score.
Review question
| Element | Planned (methods) | Found (results) |
|---|---|---|
| Population | Patients attending a dental clinic with tooth avulsion involving one or more permanent front teeth (permanent dentition); excludes avulsed primary teeth and patients whose medical history contraindicates replantation | People with avulsed and replanted permanent front teeth; children and young adults (n=4 studies; 183 participants, 257 teeth) |
| Intervention | Treatment with antibiotics; Timing of pulp extirpation; Type of root canal medicament; Replantation procedures (handling prior to replantation); Storage of the tooth prior to replantation; Fixation and stabilisation (splinting); Care following replantation (mouthwashes/mouthcare) | Extra-oral pulp extirpation at day 0 (n=1); Ledermix root canal medicament day 0 to 10 (n=1); Thymosin alpha 1 10-minute soak (n=1); Hyperbaric oxygen (n=1) |
| Comparison | No antibiotics/placebo/different antibiotics; Immediate/delayed/no extirpation; No medicament/placebo/different medicaments; Different replantation techniques; Different storage mediums/dry storage; Different splints/no splint/different splinting duration; No mouthwash/placebo/different care | Intra-oral pulp extirpation at day 7 (n=1); Ultracal root canal medicament day 7 to 10 (n=1); Saline control (n=1); Control (n=1) |
| Outcomes | Primary: Periodontal ligament healing (may include proxy outcomes such as extent of radiographic root resorption). Secondary: Tooth survival; Pulpal healing; Pain; Aesthetics (discolouration); Oral health-related quality of life; Trauma-related dental anxiety; Infraocclusion; Cost; Other complications or adverse effects | Periodontal healing (n=3); Tooth survival (n=3); Pulpal healing (n=1); Radiographic resorption proxy (n=1); Discolouration (n=1); Pain (n=1); Adverse effects (n=4, none identified) |
| Study designs | Randomised and quasi-randomised controlled trials with minimum 12 months follow-up | RCT/quasi-RCT (n=4; alternation or quasi-random sequence in 2) |
| Timing | Minimum 12 months follow-up | 12 months (n=3); 48 months (n=1) |
