Late dental and bone alterations in patients after orbital rhabdomyosarcoma treatment.

PURPOSE: Orbital rhabdomyosarcoma is a rare soft tissue sarcoma in childhood but with a good prognosis. Treatment usually includes surgery, chemotherapy, and radiotherapy. This study aimed to evaluate long-term alterations in teeth and cranial bones in children, adolescents, and young adults after oncologic treatment for childhood orbital rhabdomyosarcoma. METHOD: This was a cross-sectional study that evaluated patients treated for orbital rhabdomyosarcoma between 1988 and 2011. Demographic, clinical, and treatment data were collected during the study period; also, panoramic radiographs, cephalometric study, and photographs of the face were taken. RESULTS: Eight long-term survivors were studied. Of those, 50% were male, 75% had less than 5 years of treatment, and 88% had only one of the orbits affected by the tumor. Regarding treatment, 50% received 50.4 Gy of radiotherapy in the orbit; the chemotherapy included vincristine, actinomycin D, and cyclophosphamide in 75% of the cases and also ifosfamide and etoposide in 25%. The children presented craniofacial alterations, mainly when radiotherapy occurred between 0 and 5 years old (p = 0.01). The mandibles also showed dental alterations, probably due to chemotherapy. CONCLUSION: In conclusion, orbital RMS patients treated with chemoradiotherapy, important dental, and facial bone alterations were found. The most significant were in the maxilla and close to the irradiation field. Dental and mandibular bone alterations were also found, indicating the probable chemotherapy action, as this region was not included in the irradiation field.

Adenocarcinoma of mammary origin in the maxillary gingiva: a case report and brief literature review.

Maxillofacial metastases are rare but represent advanced disease progression and a poor prognosis. The primary purpose of this article is to describe a patient with previously diagnosed and treated invasive ductal breast carcinoma who developed a metastatic lesion in the maxillary gingiva. In addition, this article presents a brief literature review of case reports on metastatic breast cancer manifestations in the gingiva. In the present case, a 68-year-old woman had been diagnosed and treated for invasive ductal breast carcinoma. At the 6-month follow-up after treatment for breast cancer, she complained of pain in the right leg and spine, swelling in the right arm associated with redness, and a nodular growth in the maxillary gingiva that was painful, friable, and associated with tooth mobility. Imaging examinations and microscopic analysis of an oral biopsy specimen revealed disease progression to the oral cavity, femur, lung, and brain. Because of the advanced disease, the patient died within a few weeks. The literature review identified 6 articles that reported varied clinical presentations of metastatic breast cancer in the gingiva. Invasive ductal carcinoma was the most common histologic type. Routine dental follow-up of patients with cancer is essential for the identification and diagnosis of oral lesions to ensure early intervention for lesions that may be distant metastases mimicking benign lesions.

Effect of therapeutic doses of radiotherapy on the organic and inorganic contents of the deciduous enamel: an in vitro study.

OBJECTIVES: This study evaluated the effects of radiotherapy on the composition of deciduous teeth enamel using micro-energy-dispersive X-ray fluorescence and Fourier transform Raman spectroscopy before and after a pH cycling process. MATERIALS AND METHODS: Ten deciduous molars were sectioned and divided into two groups (n = 10). The radiotherapy group (RT) was irradiated with 54 Gy at 2 Gy/day, 5 days per week for 5 weeks and 2 days, and the normal group (N) was not irradiated. The RT group was evaluated before radiotherapy (RTb), after radiotherapy (RTa), and after radiotherapy and pH cycling (RTc). The normal group was evaluated before (N) and after pH cycling (Nc). The weight percentage (wt%) of calcium (Ca), phosphorus (P), and organic content; the Ca/P ratio; and the integrated area of the Raman bands relative to the organic, carbonate, and phosphate contents were also evaluated. RESULTS: The exclusive use of RT reduced the organic content of the enamel (p = 0.000). The RTc group exhibited a decrease in P wt% (p = 0.016), an increase in the Ca/P ratio (p = 0.000), and a reduction in the integrated area of the phosphate band (p = 0.046). An increase in the Ca/P ratio (p = 0.000) and a reduction in the areas of the carbonate and phosphate bands were found in the RTb/RTc treatments. CONCLUSIONS: RT application at a therapeutic dose reduced the organic content of the deciduous enamel. CLINICAL RELEVANCE: Preventive measures should be included in the patient treatment protocol because of RT-induced chemical changes to the deciduous enamel.

Clinical and image findings in bisphosphonate-related osteonecrosis of the jaws.

Bisphosphonate-related osteonecrosis of the jaws (BRONJ) is characterized as exposed bone in the jaws for more than 8 weeks in patients with current or previous history of therapy with bisphosphonates (BPs) and no history of radiotherapy in the head and neck. We report a case series of 7 patients with BRONJ and analyze the variations of clinical and imaging signs, correlating them with the presence or absence of bone exposure. Among the patients, 6 were women and 1 was a man, aged 42-79 years. Five of the patients were using zoledronic acid and the other 2 alendronate. The use of BPs varied from 3 to 13 years. In 5 patients, tooth extraction was the triggering event of injuries. Panoramic radiographs and computed tomography (CT) were evaluated by a radiologist blinded to the cases. There were persistent unremodeled extraction socket even several months after tooth extraction in 3 of the cases that were consistent wit CT findings that also showed areas of osteosclerosis and osteolysis. Patients were treated according to the recommendations of the AAOMS, with surgical debridement and antibiotic coverage with amoxicillin in the symptomatic patients. The follow-up of these patients ranged from 8 to 34 months, with a good response to treatment. The image findings in this case series were not specific and showed no difference between each stages of BRONJ (AAOMS, 2009). The image features were similar in presence or absence of exposed bone.

Dentistry consensus on HSCT - Part III: Special topics - Dentistry on HSCT.

Patients undergoing hematopoietic stem cell transplantation (HSCT) might present acute and late toxicities and the oral tissues are frequently affected. With the survival increasing, patients show late and long-term morbidities, and there is an important association between the general and the oral health. The first and second parts of this Consensus have showed the importance of the adequacy of oral health in the pre-HSCT, and the main alterations and oral care during the period of admission for HSCT. This third part aims to review specific themes of post-HSCT dental care, such as graft-versus-host disease (GVHD) and the pediatric patient. It also aims to review pertinent subjects, both during the HSCT period and post-HSCT, concerning quality of life, pain, cost-effectiveness, and remote care. Based on this review, it is evident the importance of the work of the dental surgeon (DS) in the follow-up and treatment of the HSCT patient, always collaborating with the whole multidisciplinary team.

Dental consensus on HSCT - Part II: dental Care during HSCT.

During the state of immune vulnerability in hematopoietic stem cell transplantation (HSCT), the patient has an increased risk of developing a vast number of complications, including severe problems in the oral cavity. These situations require professional oral care to act in the diagnosis and treatment of these conditions, as well as to develop prevention protocols to minimize patient's complications. Oral mucositis, opportunistic infections, bleeding, specific microbiota, taste, and salivary alterations are complications that can occur during HSCT and interfere with various aspects, such as pain control, oral intake, nutrition, bacteremia and sepsis, days of hospitalization and morbidity. Several guidelines have been published to address the role of professional oral care during the HSCT, we describe a consensus regarding these recommendations.

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

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 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.

Anti-inflammatory and wound healing effect of Copaiba oleoresin on the oral cavity: A systematic review.

Copaiba oleoresin has been related to properties including healing and anti-inflammatory effects, making it a potential candidate to treat oral lesions. We aimed to define the benefits related to the anti-inflammatory and healing capacity of Copaiba-based formulations on the oral cavity. This is a systematic review, conducted in PubMed, Web of Science, Scopus, Embase, Scielo, Cochrane Library, BVS, and Google Scholar databases selecting full articles in English, Portuguese, or Spanish, until March 3rd, 2021. Pre-clinical, clinical, or randomized clinical trials, cohort and case-control in vivo studies were included; studies with other designs, in vitro, and those that did not match the PICO question were excluded (PROSPERO: CRD42021244938). Data was collected and synthesized descriptively through a specific form. The risk of bias was evaluated by SYRCLE's RoB Tool. So, five studies were included. Two reported beneficial wound healing effects, such as early reduction in the wound area and greater immature bone formation in the rats' mandibles; and two related benefic anti-inflammatory effects, like reduced acute inflammatory reaction and more advanced tissue repair stage, early formation of collagen fibrils, with greater quantity, thickness and better organization, and more expressive anti-inflammatory activity, reduction of the edema intensity and the CD68 + macrophages concentration. Based on the articles, benefits related to the wound healing and anti-inflammatory effects in the oral cavity of rats treated with Copaiba oleoresin were suggested. However, due to the limited data, future studies are necessary, especially clinical ones.

Successful GaAlAs low-level laser therapy of self-inflicted thermal burns of the palate.

Thermal burns of the oral cavity usually arise from ingestion of hot foods or beverages. A 38-year-old female patient presented with two painful ulcerative erythematous patches of the palate. The patient was consulted on the same day lesions appeared. Medical history was unremarkable. Clinically significant self-inflicted injuries may result in wide ulcers in the mouth and usually do not take less than 2 weeks to heal, whereas our patient, treated with low-level laser therapy, had a complete response in day 4, after 2 days of treatment. The fact that multiple lesions were present signaled against the World Health Organization exclusion diagnosis of erythroplakia for red patches. A traumatic ulcer, regardless of its cause of origin, usually heals within 2 weeks, after the source of injury is resolved. A thermal burn in the oral cavity usually takes longer than that to heal, but whenever this time frame is not respected, the suspicion of a potentially malignant disorder should always arise, and a biopsy should be performed. The present case showed two painful thermal burns with great results in terms of speeding up the relieve of symptoms and healing time with soft laser as opposed to the traditional treatment with oral topical corticosteroid.

Streptococcal bacteraemia in patients submitted to hematopoietic stem cell transplantation: the role of tooth brushing and use of chlorhexidine.

A retrospective evaluation of 73 consecutive recipients of hematopoietic stem cell transplantation (HSCT) was conducted to investigated the role of oral care and incidence of streptococcal bacteremia in patients submitted to hematopoietic stem cell transplantation. Patients were retrospectively evaluated and divided into group A (GA=38) and group B (GB=35). During hospitalization patients from GA performed oral hygiene daily with extra soft toothbrush and toothpaste besides performing mouth cleaning with an ethanol-free 0.12% chlorhexidine solution tree times a day. In contrast GB patients performed mouth cleaning with extra soft toothbrush and toothpaste, but no chlorhexidine was used. Using the Chi square test it was observed that all patients from GA presented negative blood culture for alpha-hemolytic Streptococcus viridans and Candida albicans and only 1 patient without oral mucositis from GB presented positive blood cultures for Streptococcus intermedius (p=0.48). The results indicate that methodology used for oral care before the HSCT and the practice of tooth brushing during the period were effective in preventing streptococcal bacteremia. Moreover, our data suggest that the mouth cleaning with chlorhexidine during HSCT may be not mandatory.

Dental and craniofacial alterations in long-term survivors of childhood head and neck rhabdomyosarcoma.

OBJECTIVE: Rhabdomyosarcoma (RMS) represents the most common soft tissue sarcoma that affects children. Treatment involves chemoradiotherapy. This study aimed at evaluating the long-term alterations to teeth and cranial bones in children, teenagers, and young adults after oncologic treatment. STUDY DESIGN: We conducted a cross-sectional study of patients undergoing treatment for head and neck RMS between 1988 and 2011. We evaluated demographic, clinical, and treatment data and performed panoramic radiography, cephalometry, and photography. RESULTS: We evaluated 27 long-term survivors, most of whom had been treated between ages 0 to 5 years (51.9%). The total radiation dose applied was 50.4 Gy, and the chemotherapy combination included vincristine, actinomycin D, and cyclophosphamide in 51.9% of the cases. We observed 603 dental alterations, among which 377 (62.7%) occurred in patients ages 0 to 5 years, and root shortening was the most frequent alteration observed (24.2%). With regard to facial bones, 74% of the patients had some level of facial asymmetry, 70.4% had reduced facial depth, 48.4% had mandibles of short size, and 77.8% had reduced facial height. CONCLUSIONS: Children submitted to RMS treatment involving chemotherapy and radiotherapy displayed significant dental and craniofacial alterations, especially when treatment occurred between ages 0 and 5 years.

Tongue cancer epidemiology in Brazil: incidence, morbidity and mortality.

BACKGROUND: The purpose of this current research was to clarify for the scientific community the trends of tongue cancer epidemiology in Brazil. METHODS: The data came from Population Based Cancer Registries, Hospital Cancer Registries, and Mortality Information System from 2000 to 2014. RESULTS: The age-adjusted incidence rate are increasing in both men and women for base of tongue cancer and for other and unspecified parts of the tongue in women, and decreasing in men for other and unspecified parts of the tongue. The majority of cases were diagnosed at clinical stages III and IV. The mortality rate remained relatively stable in both men and women in the period studied. CONCLUSION: The increase in age-adjusted incidence rate for tongue cancers (except for other and unspecified parts of the tongue in men), with most patients over 50 years of age, with low education levels, and advanced disease reinforces the need for interventions that address access to health promotion resources and medical care in Brazil.

Introduction: Chronic graft-versus-host disease (cGVHD) is the main cause of morbidity and mortality after allogeneic hematopoietic stem cell transplantation (HSCT-alo). Case Report: Dental follow-up of a 59-year-old male patient, with initial diagnosis of acute myeloid leukemia, who underwent HSCT-alo in May 2017. At D+ 224, the patient developed a condition of GVHD affecting the skin, oral cavity and gastrointestinal tract, but with still healthy teeth. On D+ 392, the patient complained of dry mouth, oral lesions were observed, and sialometry was 0.024mL/min, with evolution of carious lesions on teeth 17, 15, 22, 25, 27, 38, 45 and 46. At D+ 560, the patient still had oral GVHD and the progression of caries was observed in numerous teeth. Treatment and Results: The therapeutic management adopted consisted of the use of silver diamine fluoride due to its cariostatic property with reduced tooth pain and later dental restorations were performed. In addition, the patient received guidance about diet, maintenance of oral hygiene and - use of oral lubricant to ease xerostomia. Conclusion: It was observed in this clinical case that silver diamine fluoride was effective in controlling the evolution of caries and reducing tooth pain in adult patients. It is evident the importance of training dentists on the knowledge about the use of cariostatic resources in patients with changes in the quality and quantity of saliva, such as patients with oral GVHD

Conclusión: Se observó en este caso clínico que el diamino fluoruro de plata fue efectivo para controlar la evolución de la caries y reducir el dolor dental en pacientes adultos. Es evidente la importancia de capacitar a los dentistas con respecto al conocimiento sobre el uso de recursos cariostáticos en pacientes con cambios en la calidad y cantidad de saliva, como los pacientes con EICH oral

Panorama Atual dos Programas de Residência Multiprofissional em Oncologia para Cirurgiões-Dentistas do Brasil / Current Portrait of Multiprofessional Residency Programs in Oncology for Dentist in Brazil / Panorama Actual de los Programas de Residencia Multiprofesional en Oncología para Cirujanos-Dentistas en Brasil

Introdução: Os Programas de Residência Multiprofissional constituem-se uma estratégia fundamental para a ampliação da capacidade para o enfrentamento do câncer. Objetivo: Analisar o panorama atual dos Programas de Residência Multiprofissional em Oncologia para cirurgiões- -dentistas no Brasil, bem como o número de profissionais egressos desses cursos, a partir de dados informados pelo Ministério da Educação (MEC). Método: Trata-se de um estudo quantitativo, exploratório. A primeira fase consistiu na solicitação à Equipe Técnica da Residência Multiprofissional do MEC do Brasil da relação de todos os Programas de Residência Multiprofissional em Oncologia que incluíssem a categoria profissional da odontologia. Adicionalmente, foi realizada busca manual. Na segunda fase, realizaram-se contato por e-mail e busca pelos editais disponíveis na Internet dos casos em que não houve resposta. Os dados investigados foram a presença de Programa ativo, inclusão da categoria profissional da odontologia, número de vagas ofertadas e de egressos para cada ano entre 2010 e 2020, que foram analisados descritivamente. Resultados:Foram identificados 13 Programas de Residência Multiprofissional em Oncologia para cirurgiões-dentistas, distribuídos em 12 centros, situados em dez cidades de oito Estados brasileiros, sobretudo, na Região Sudeste.
