“…This study found an overall tooth survival rate of 65.3% within a mean observation period of 3.5 years for replanted avulsed teeth. This is considerably inferior to the success rates of most other treatment procedures in modern dentistry, including dental traumatology, but it is in line with other reports on replanted avulsed teeth, showing survival rates between 50.0% and 83.3% [16][17][18]20,27,28 and emphasizing the severity of this specific type of TDI. The most desirable outcome after avulsion is functional healing, which was observed in 26.5% (N = 13/49) of all monitored cases and did not lead to the loss of a single tooth during the observation period (Fig.…”

“…Mainly, the study was based on a longitudinal recall over several years of caring for patients who received dental care due to avulsion between 2004 and 2017. Long-term and detailed data for TDI cases, especially the avulsion of permanent teeth, have been rare in the last decade 16,17,20 ; therefore, current information is required to reflect the present state of clinical practice. Although a practice-based, retrospective study design is often considered less optimal, particularly due to the possibility of missing information (Tables 1-3), this design might still be the most feasible approach to study the outcome of replanted permanent teeth in humans under real-life circumstances.…”

this retrospective clinical study investigated the survival probability of avulsed and replanted permanent teeth in relation to functional healing, replacement and inflammatory resorption. The explorative data analysis included data from 36 patients and 49 replanted permanent teeth with a minimum observation time of 60 days; the patients were generally treated according to the current guidelines of the international Association of Dental traumatology at the university hospital in Munich, Germany, between 2004 and 2017. The mean observation period was 3.5 years. Functional healing was observed in 26.5% (N = 13/49) of the included avulsion cases. In comparison, replacement resorption affected 51.0% (N = 25/49) of the replanted teeth, of which 24.0% (N = 6/25) were lost over the course of years (mean, 6.1 years). In contrast, inflammatory resorption resulted in the early loss of all replanted teeth (mean, 1.7 years) and affected 22.5% (N = 11/49) of all the monitored teeth. Therefore, it can be concluded that tooth avulsion remains a severe dental injury with an unpredictable prognosis.

“…The observational studies evaluated the success of replantation by clinical and radiographic examinations of functional and periodontal healing of the avulsed and replanted teeth. These outcomes involved healing in the absence of surface resorption, replacement resorption, inflammatory resorption, and/or ankylosis 11,19,37 …”

Background/Aim It is crucial to store an avulsed tooth appropriately to preserve the viability of the periodontal ligament cells prior to replantation. The aim of this systematic review was to identify the best available evidence for the effectiveness of any technique available to laypeople for storing an avulsed tooth compared with storage in milk or saliva. Methods The following databases were searched (September 2019): Cochrane Library, MEDLINE, and Embase. Two reviewers independently considered trial eligibility, then extracted and analyzed data, and assessed the risk of bias. The certainty of the body of evidence was appraised according to the GRADE methodology. Results Out of 4118 references, 33 studies were included and reported 23 comparisons of which 10 were synthesized in a meta‐analysis. The limited evidence available favors storing an avulsed tooth in Hank's balanced salt solution (pooled SMD 2.47, 95% CI [1.59;3.34], P < .00001), propolis solution (pooled SMD 1.73, 95% CI [1.12;2.33], P < .00001), oral rehydration salts (pooled SMD 4.16, 95% CI [2.10;6.23], P < .0001), rice water, and cling film compared with storage in milk. The cell viability rate was significantly lower in teeth stored in saline solutions (pooled SMD −4.35, 95% CI [−7.55;−1.14], P = .008), tap water, buttermilk, castor oil, GC Tooth Mousse, and turmeric extract than those stored in milk. There is insufficient evidence to recommend for or against temporary storage of an avulsed tooth in saliva compared with alternative solutions. The certainty of evidence was considered low to very low due to limitations in study design, indirect study populations and outcome measures, and imprecision. Conclusion Although milk was shown to extend the periodontal ligament cell viability before replantation compared with saline or tap water, the following media have also demonstrated efficacy at preserving the cell viability: Hank's balanced salt solution, propolis, oral rehydration salts, rice water, and cling film.
