Brazilian dental consensus on dental management in hematopoietic stem cell transplantation−Part I−pre-HSCT

ABSTRACT The oral involvement in the Hematopoietic Stem Cell Transplantation is well described in the literature. The goal of the dental treatment and management of the oral lesions related to the HSCT is to reduce the harm caused by preexisting oral infection or even the worsening of oral acute/chronic GVHD and late effects. The aim of this guideline was to discuss the dental management of patients subjected to HSCT, considering three phases of the HSCT: pre-HSCT, acute phase, and late phase. The literature published from 2010 to 2020 was reviewed in order to identify dental interventions in this patient population. The selected papers were divided into three groups: pre-HSCT, acute and late, and were reviewed by the SBTMO Dental Committee's members. When necessary, an expertise opinion was considered for better translating the guideline recommendations to our population dental characteristics. This manuscript focused on the pre-HSCT dental management. The objective of the pre-HSCT dental management is to identify possible dental situations that On behalf of the Dental Committee of the Brazilian Society of Gene Therapy and Bone Marrow Transplantation (SBTMO) can worsening during the acute phase after the HSCT. Each guideline recommendations were made considering the Dentistry Specialties. The clinical consensus on dental management prior to HSCT provides professional health caregivers with clinical setting-specific information to help with the management of dental problems in patients to be subjected to HSCT.

Assessment of oral health condition in recipients of allogeneic hematopoietic cell transplantation

ABSTRACT Objective: The objective of this study was to evaluate the oral health condition and dental treatments performed in patients in pre-allogeneic HCT. Method: The records of patients treated during 2018 at a Brazilian HCT service were reviewed. The following oral health data were obtained: 1. Decayed, missing and filled teeth / correlated index for primary dentition (DMFT/dmft); 2. Quality of oral hygiene and 3. Dental pathologies: 3.1 Periodontal infectious focus, 3.2 Endodontic infectious focus and 3.3 Carie incidence. All dental procedures performed were surveyed. Results: Thirty-three patients were included, with a mean age of 28.42 (±16.37), 20 male (60%) and 13 female. The average DMFT/dmft found in this study was 10.24 (± 8.37), similar to the index found in the population in southeastern Brazil. The younger study population presented a DMFT/dmft considered high, when compared to the general population. A total of 27.2% of the patients had active caries lesions, 33.3%, foci of periodontal infection, 15.1%, endodontic infectious focus and 40%, poor oral hygiene. Almost half of the patients (48.4%) had to undergo dental intervention, 24.2% needing periodontal scaling, 21.2%, fillings and 12.1%, tooth extractions. Conclusion: We conclude that the studied population had an important incidence of dental pathologies and infectious conditions that could complicate throughout HCT, especially in younger patients, therefore presenting a high demand for dental treatment in the pre-HCT. Studies that assess the impact of dental conditioning on the outcomes of HCT with an emphasis on dental infectious complications, days of hospitalization and survival are necessary."
