Objective To examine how hospital-affiliated dentists assess risk and evaluate oral foci of infection in patients facing certain medical treatments, and whether the nature of upcoming medical treatment affects the choice of dental intervention. Materials and methods A survey comprising six clinical cases (50 teeth) was sent to hospital-affiliated dentists in Sweden. A treatment option for the affected tooth/teeth in each case was selected whether the patient was facing heart valve surgery, chemotherapy, radiation therapy, intravenous bisphosphonate treatment, solid organ transplantation or was diagnosed with endocarditis. Results Consensus in choice of dental treatment was high in 62%, moderate in 32% and low in 6% of the assessments. High variability of choice of treatment was seen for eight teeth whereas the remaining 42 teeth often received the same therapy regardless of medical issue. Chemotherapy and radiotherapy were thought to entail the highest risk for oral infectious sequelae with a risk ranging from 1% to 100%. Conclusion Pre-medical dental evaluations and recommended treatments are often uniform with the exception of the management of asymptomatic root canal treated teeth with persisting apical radiolucency and heavily decayed molars. In many instances, dental diagnosis has a greater impact on choice of treatment than the underlying medical issue and associated implications thereof.

AIM: Prior to certain medical therapies, dental assessment and treatment of oral foci of infection are recommended. The aim of the present study was to acquire a deeper understanding of the decision-making process regarding pre-medical management of root canal-filled teeth with asymptomatic apical periodontitis.

METHODOLOGY: Hospital-affiliated dentists in Sweden were contacted for a semi-structured, in-depth interview. The absolute inclusion criterion was that the dentists had experienced and could recount at least two authentic cases involving root canal-filled teeth with asymptomatic apical periodontitis - one case having resulted in pre-medical treatment, and one having resulted in expectancy. Fourteen interviews, with fourteen informants, were conducted and included in the study. During the interviews, open-ended questions and comments encouraging the informants to elaborate and clarify their experiences were offered. The interviews were digitally recorded, transcribed verbatim and analyzed using Qualitative Content Analysis with an inductive approach.

RESULTS: A theme describing the latent content was identified through interpretation of the collected data: A multifaceted balancing act characterized by a sometimes-difficult risk-benefit-estimation, where an increased uncertainty entails an increased reliance on external opinions. Three main categories, comprising four subcategories, describing the manifest content were recognized: The tipping scale, The team effort and The frame of reference.

CONCLUSION: The current interview study found pre-medical decision-making regarding root canal-filled teeth with asymptomatic apical periodontitis to be a multifactorial and contextual process marked by uncertainty and collaborative measures. Further research, resulting in the development of evidence-based treatment guidelines, is suggested necessary.

Objectives: Posttransplant infections may lead to dire consequences in immunocompromised organ recipients. Oral foci of infection are therefore often eliminated prior to solid organ transplantation to reduce posttransplant morbidity. However, despite increasing numbers of organ transplantations the necessity of pretransplant dental treatment and its effect on transplant outcome remains uncertain. The aim of the present systematic review was to evaluate the impact of oral foci of infection and pretransplant dental treatment on adverse events following solid organ transplantation.

Methods: Studies on adult patients undergoing solid organ transplantation with/without oral infection or with/without pretransplant dental treatment were eligible. An electronic search in PubMed, Scopus, Web of Science, CINAHL and Cochrane was conducted up to June 11, 2024. Screening of eligibility, data extraction and risk-of-bias assessment of the included studies with the Newcastle-Ottawa Scale were done independently by two reviewers. Data were synthesized with a narrative approach.

Results: In total, 4035 unique publications were identified. After full text assessment of 75 studies nine cohort studies on liver, kidney, heart and/or lung transplantation based on 727 patients were included. Two studies based on 161 patients found a significant increase of infectious complications after liver transplantation when no dental treatment was performed. Presence of oral foci increased the risk of hospitalization after kidney transplantation in one study but was associated with lower infection rate after lung transplantation in another study. No studies found significant impact on mortality or on organ rejection. Overall, the quality of the included studies was good with low or medium risk-of-bias.

Conclusion: To our knowledge, this is the first systematic review on the impact of oral infection on organ transplantation. The results suggest a possible link between persisting oral infection and posttransplant infectious complications, thus lending support to the elimination of oral infectious foci before solid organ transplantation.
