“…A recent systematic review [ 23 ] evaluated the histopathological and microbiological findings associated with RPI. In the six studies included, 21/30 dental implants with a RPI diagnosis were associated with failed endodontic treatment, apical periodontitis or remaining infected roots at the implant site.…”

“…There is no consensus about RPI aetiology: the main possible causes hypothesised are implant insertion in a site with a pre-existing unhealed infection or inflammation [ 21 ], implant placement in a site that previously housed an endodontic treated tooth with further bacteria reactivation [ 22 , 23 ], pulpal/periapical endodontic lesions at adjacent teeth or bone overheating during implant drilling [ 24 , 25 ]. Furthermore, also, implant placement in a longer prepared osteotomy site has been reported as a probable cause of asymptomatic periapical lesions at the implant site [ 16 , 21 ].…”

Objectives The aims of this retrospective study were to report data on the prevalence of retrograde peri-implantitis (RPI) in a single-center in a 20-year observation period and to evaluate implant survival after surgical treatment. Materials and methods A retrospective cohort study was conducted screening all patients who underwent implant treatment in a private practice. Patients were enrolled if they had one or more implants showing a radiolucency around the implant apex, without implant mobility. Furthermore, clinical symptoms of RPI and days from symptoms’ appearance after implant placement were also collected, as well as periodontal and endodontic status of nearby teeth. All patients were treated with the same surgical approach: antibiotic therapy, mechanical curettage, chemical decontamination and xenograft application. Results Out of the 1749 implants placed, only 6 implants were classified as affected by RPI, with a prevalence of 0.34%. Clinical symptoms of RPI (pain, swelling, dull percussion or fistula presence) varied among patients and were reported after a mean period of 51.83 ± 52.43 days. Conclusions RPI was successfully treated with surgical curettage and bone substitute application and all implants are still in place after a mean follow-up of 8.83 ± 5.34 years. Clinical relevance Bacteria from teeth with failed endodontic treatment or residual lesions might be reactivated by drilling for implant osteotomy, with subsequent colonization of the implant apex and possible failure before prosthetic loading. Therefore, it might be recommended to take a periapical x-ray at implant placement and after 6–8 weeks in order to intercept RPI before prostheses delivery.

“…In a recent systematic review, it was reported that 35.7% of RPI cases will eventually lead to implant removal 47 . Other groups have provided detailed classifications and decision‐trees to aid in deciding whether surgical intervention or implant removal is recommended, which the readers are encouraged to review 47,48 …”

Background Retrograde peri‐implantitis (RPI) is a rapidly progressing periapical infection that forms around the implant apex. It is usually associated with sites adjacent to teeth with apical lesions; previous endodontic failures, retained root fragments, etc. This study aimed to study the incidence of RPI in sites with a history of apical surgeries. Methods Patients with sites treated for both apicoectomy and implant placement presenting to the University of Michigan School of Dentistry from 2001 to 2016 were screened. A total of 502 apicoectomies were performed, only 25 of these fit the predetermined eligibility criteria and were thus included in this retrospective analysis. Results Implants that were placed in sites with a previous apical surgery had a cumulative survival rate of 92%. The incidence of peri‐implantitis was 8%, while the incidence of RPI was 20%. There was an increased trend for RPI in cases where the cause of extraction was persistent apical periodontitis (35.7%), but this increase didn't reach the level of statistical significance (P = 0.061). Conclusion Implants placed in sites with previous apical surgery are not at an increased risk of implant failure or RPI.

“…Furthermore, systematic reviews of aetiology have a limitation regarding the study design of component studies, considering that it would be unethical to carry out longitudinal experimental studies (i.e. causing an intentional injury), for example . (ii) Studies with intentional injury may not represent clinical reality and are only followed up for a relatively short duration.…”

This review, registered in PROSPERO (CRD42018102582), assessed the effect of temporary anchorage device placement on endodontic complications. A search strategy was followed to identify studies where any temporary anchorage devices contacted or were in proximity to tooth roots in humans. Studies with low possibility of bias and published in English or Latin-character languages were considered for inclusion. Ten studies were identified; five case reports, one clinical study and four studies with intentional injury, totalling 736 temporary anchorage devices in 327 patients. Complications may ensue following temporary anchorage device placement, whether or not root contact occurs. Chronic apical periodontitis developed when there was root injury involving the pulp; necrosis can also occur. When damage was limited to the periodontal ligament, cementum or dentine, repair occurred, normally within 12 weeks. Clinicians should be aware of the potential for endodontic complications during temporary anchorage device placement, as well as during orthodontic treatment.
