Association between the time after transplantation and different immunosuppressive medications with dental and periodontal treatment need in patients after solid organ transplantation

Association between the time after transplantation and different immunosuppressive medications with dental and periodontal treatment need in patients after solid organ transplantation



Aim of this study was to investigate the association of time after transplantation and different immunosuppressive medications with dental and periodontal treatment needs in patients after solid organ transplantation (SOT).


After lung, liver or kidney transplantation, patients were included and divided into subgroups based on the time after SOT (0-1, 1-3, 3-6, 6-10 and >10 years) and immunosuppression (Tacrolimus, Cyclosporine, Mycophenolate, Glucocorticoids, Sirolimus and monotherapy vs. combination). Dental treatment need was determined by the presence of carious lesions, while periodontal treatment need was diagnosed based on a Periodontal Screening index score of 3-4. The overall treatment need included both the dental and/or periodontal treatment needs. Statistical analysis was performed using the Kruskal-Wallis test and Chi²-test (p<0 .05="" p="">


A total of 169 patients were included after SOT. A dental treatment need of 44%, a periodontal treatment need of 71% and an overall treatment need of 84% were detected in the total cohort. Only patients with >10 years after SOT had a lower dental treatment need compared to the other groups (p=0.02). All other comparisons of dental, periodontal and overall treatment needs were comparable between subgroups depending on time since SOT. Furthermore, no statistically significant differences were found in terms of the dental, periodontal or overall treatment needs following the administration of different immunosuppressive medications.


The high treatment need of patients after SOT, irrespective of the time since transplantation, suggests insufficient dental and periodontal treatment before and maintenance after organ transplantation. Furthermore, immunosuppressive medication was not associated with the treatment need.

What is the role of the dentistry in organ transplants?

What is the role of the dentistry in organ transplants?

Infections of oral origin are a potential threat for transplant candidates
because oral diseases tend to be more severe and untreated in people
who have received transplants. Although not yet scientifically proven,
evaluation and dental treatment during the pre-transplantation period is
recommended in order to prevent infections and resulting odontogenicorigin
sepsis during the post-transplant period, when patients receive
immunosuppressive therapy.1
Careful oral examination and evaluation of the patient, including
laboratory tests, is recommended in order to ensure correct oral preparation
and control of oral disease prior to organ transplantation (OT). Patients
with chronic diseases that lead to OT may present at any dental office for
treatment and therefore general dentists should be aware of the unique
concerns involving their assessment, education, treatment and maintenance
of oral health.2
The equilibrium between viral persistence and immune regulation of the
host is modified in many immunological conditions related to OT. Among
the opportunistic oral infections that can cause some impairment in these
patients, the most common are fungal infections, and viral infections
by CMV and HSV, and must be diagnosed early by a dentist.3 The use
of systemic medications can affect the periodontal tissues, modifying
their inflammatory and immune response, especially the gingiva. Some
immunosuppressive drugs used in OT may trigger gingival hyperplasia.4
Because of the conditions above described it is considered that the
communication between the organ transplant team and dentist is
important in formulating individualized care plans and transplant
patients need comprehensive and regular dental care during the pre
and post-transplant period and a doctor of oral medicine should be part
of a multidisciplinary team of medical specialists.5 Appropriate dental
care increases the survival of the transplanted organ.

To report a case of severe dystrophic calcification in maxillary sinus of a child with liver transplantation and dental organs pigmented by hyperbilirubinemia.
Case description:
female patient, 12 years old, with liver transplantation performed at the age of 7 due to extrahepatic biliary atresia (EHBA). The patient was receiving the immunosuppressant tacrolimus (2 mg daily). Intraoral clinical exam showed tooth green pigmentation by bilirubin. Cone-beam volumetric computed tomography (CT) was performed to verify radiographic density of pigmented dental elements. Hounsfield scale measurement did not show changes in radiographic density of dental structures. However, CT scan showed intense dystrophic calcification in the maxillary sinus region.
CT scan indicated relevant radiographic findings, with radiopacity of the maxillary sinus due to fungal or non-fungal sinusitis. This case report highlights the presence of radiographic image associated with acute infectious processes that could compromise the systemic state of immunosuppressed patients.

The aim of this single-centre, cross-sectional study was to evaluate dental, periodontal and mycological findings, as well as oral behaviour, in patients before (pre-LTx) and after (post-LTx) liver transplantation.


A total of 47 patients pre-LTx and 119 patients post-LTx were asked to participate. Oral health behaviour was assessed using a standardised questionnaire. Oral examinations included dental [decayed, missing and filled teeth (DMFT) index] and periodontal [papillary bleeding index (PBI), periodontal probing depth (PPD) and clinical attachment loss (CAL)] findings. For Candidascreening, swabs from the oral mucosa were cultured. Statistical analysis was performed using the Student's t-test or the Mann–Whitney U-test, depending on whether or not the data followed a normal distribution; Fisher's exact test was also performed. The significance level was α = 5%.


A total of 110 patients were included (pre-LTx, n = 35; post-LTx, n = 75). Different patients were investigated in the post-LTx and pre-LTx groups. Lack of use of supplemental oral-hygiene aids was noted. Between-group comparisons failed to find significant overall differences in DMFT and periodontal status. The post-LTx group showed fewer decayed teeth (P = 0.03). A total of 86% of patients pre-LTx and 84% of patients post-LTx were found to need dental treatment, and 60% of patients pre-LTx and 55% of patients post-LTx showed a need for periodontal treatment. The prevalence of Candida albicans was high; however, there were no statistically significant differences between the groups in regard to fungal infection.


Improved dental care pre- and post-transplant, including screening for fungal infections, is recommended to avoid systemic infections in LTx patients. Increased attention to oral health care, and interdisciplinary collaboration to provide guidance, is needed to improve the oral health of patients before and after LTx.

Manejo odontológico em paciente com Linfoma não Hodgkin submetido a transplante autólogo de células tronco hematopoiéticas - Dental care in patient with nonHodgkin lymphoma and autologous stem cell transplantation

Manejo odontológico em paciente com Linfoma não Hodgkin submetido a transplante autólogo de células tronco hematopoiéticas - Dental care in patient with nonHodgkin lymphoma and autologous stem cell transplantation

O linfoma não Hodgkin (LNH) é o nome que se dá a um grupo heterogêneo de doenças, sendo uma neoplasia maligna de células B, T ou Natural Killer que se infiltram nessas células linfoides ou hematopoiéticas normais. Sua etiologia ainda permanece desconhecida, no entanto inúmeros fatores imunológicos e imunodeficiências parecem estar envolvidos em seu desenvolvimento. O tratamento varia de acordo com o subtipo do LNH, podendo dessa forma levar a cura dos pacientes em 50% dos casos. O Objetivo desse trabalho é relatar detalhadamente o manejo odontológico em uma paciente diagnosticada com LNH, submetida a tratamento quimioterápico concomitante ao radioterápico e posterior transplante autólogo de células tronco hematopoiéticas. A paciente foi submetida a diversos procedimentos odontológicos dentre eles endodôntico, restaurador dentário, reabilitador protético e cirurgia oral, posterior a anamnese e confirmação de condições clínicas e laboratoriais favoráveis que não contra indicavam o manejo odontológico. A atuação do cirurgião dentista sobre os pacientes oncológicos tem se mostrado ao longo dos anos primordial, sobretudo no que diz respeito as manifestações bucais que o tratamento pode gerar. No entanto, o cuidado com o paciente deve
ocorrer antes, durante e após o tratamento, com adequação do meio bucal, acompanhamento a intercorrências durante o tratamento e restabelecimento no pós tratamento.

The nonHodgkin's lymphoma (NHL) is the name given to a heterogeneous group of disorders, a malignancy of T, B, or natural killer cells. They are infiltrating these normal lymphoid or hematopoietic cells. Its etiology remains unknown. However, numerous immune factors and immune deficiencies appear to be involved in their development. The treatment varies depending on the subtype of NHL and it may thus lead to the cure of patients in 50% of cases. The aim of this work is to report in detail the dental management in a patient diagnosed with NHL, underwent chemotherapy as well as radiotherapy and subsequently autologous transplantation of hematopoietic stem cells. The patient was submitted to various dental procedures among them endodontics, dental restorative, rehabilitative prosthetics and oral surgery treatments. The subsequent history and confirmation of favorable clinical and laboratory conditions was not contraindicated for the dental management. The role of the dentist on cancer patients has been important over the primary years, especially regarding the oral manifestations that treatment can generate. However, patient care should take place before, during and after cancer treatment. It is possible with the adequacy of the oral environment,
monitoring the events during the treatment and the recovery in the post treatment.

Artigo RBM Transplantes - A equipe multidisciplinar e a ação do cirurgião dentista nos pacientes transplantados renais: uma revisão integrativa

Objective: To establish the major dental aspects in candidates to kidney transplantation (KT) or those who have received the transplant. Methods: Search through the PubMed database. The last articles were selected into five years (2011-2016) using the terms "oral" and "care" and "kidney transplantation" (26 articles) and "kidney transplant" and "oral health" (5 articles). We excluded studies that did not report dental approach, which were not in English and those who were not available to access, resulting in nine articles included. They were tabulated the main findings of interest to dentistry in the group pre / post KT patients as well as the conduct adopted by the authors. Results: Of the nine included articles, two articles were relevant to the pre-KT period, five for the post-KT, and two made a comparative study between the pre- and post-KT. Dental aspects in pre-KT period were: high DMFT index as well as tooth loss and gingival hyperplasia. In the post-KT period were: a poor oral hygiene that was related as a transplant rejection factor, an oral candidiasis and an osteonecrosis by bisphosphonates (OPB). In studies comparing patients on hemodialysis and post-KT patients was found: DMFT index was higher in pre-KT patients and periodontitis was higher in post-KT patients. Conclusions: A multidisciplinary team of renal transplant patients should have the participation of the dentist, as helps to reduce comorbidities related opportunistic infections, increasing the survival of the transplanted organ.

Hiperplasia gengival medicamentosa associada ao uso de Ciclosporina-A após transplante renal Gingival overgrowth induced by CsA after kidney transplantation


Paciente mulher com 51 anos de idade apresentou-se à Clínica Multidisciplinar da Faculdade de Odontologia de Bauru-USP com a seguinte queixa: eu sou transplantada e tenho gengivite. O histórico médico incluía transplante renal, infecções urinárias recorrentes, diabetes pelo uso de corticoides, hipertensão e arritmia cardíaca. Relatou o uso de ciclosporina-A, metformina, omeprazol, imunossupressores e anti-hipertensivos. Ao exame clínico intraoral observou-se hiperplasia gengival inflamatória generalizada e língua saburrosa. A radiografia panorâmica indicou reabsorção óssea moderada, e lesões periapicais nos dentes 1ºMSE e 1ºMID. O hemograma apontou discreta leucocitose e série vermelha normal. A análise bioquímica revelou elevação de ferritina, creatinina, glicose e potássio. O plano de tratamento odontológico incluiu adequação bucal por meio de profilaxia de placa bacteriana dental com ultrassom, raspagem e curetagem subgengival e supragengival, exodontia do 1ºMSE, prescrição de bochecho com solução de clorexidina 0,12% aquosa e uso de escova dental de cerdas extra-macias. O objetivo deste relato de caso clínico é descrever a conduta odontológica sem necessidade de modificação da terapêutica imunossupressora em pacientes transplantados renais e o impacto desta ação na qualidade de vida.
