Survival of Dental Implants in Oncology Patients versus Non-Oncology Patients: A 5-Year Retrospective Study.

Patients with a history of cancer are increasingly common in the dental office. Treating cancer patients requires a multidisciplinary team, which should include the dentist, in order to control the complications that occur in the oral cavity and also to recover the patient undergoing treatment in any of its types: surgical, medical, radiotherapeutic, or its possible combinations. Dental implants can be a safe and predictable treatment option for prosthetic rehabilitation. The aim of this paper is to describe in retrospect the success rate of osseointegrated implants in oncology and non-oncology patients placed by the Master of Dentistry in Oncology and Immunocompromised Patients, as well as the Master of Medicine, Surgery and Oral Implantology of the University of Barcelona Dental Hospital, between July 2011 and March 2016. 466 patients were reviewed, with a total of 1405 implants placed, considering the oncological history of the patients and the implant success rate. The total success rate in the concerned period was 96.65%. When comparing cancer patients with healthy ones, the success rate has been 93.02% in the first case, and 97.16% in the latter. According to the literature review, our results encourage implant placement in cancer patients, it is important to recognize that this is an analysis of a complex care pathway with a large number of confounding variables. However, the findings should not be considered as generalizable.

Resumo Pacientes com histórico de câncer são cada vez mais comuns no consultório odontológico. O tratamento de pacientes com câncer requer uma equipe multidisciplinar, que deve incluir o dentista, a fim de controlar as complicações que ocorrem na cavidade oral e também para tratar o paciente com qualquer uma das modalidades de tratamento: cirúrgica, médica, radioterápica ou suas possíveis combinações. Os implantes dentários podem ser uma opção de tratamento segura e previsível para reabilitação protética. O objetivo deste artigo é propor um estudo retrospectivo sobre a taxa de sucesso de implantes osseointegrados em pacientes oncológicos e não oncológicos atendidos no Mestrado em Odontologia em Pacientes Oncológicos e Imunodeprimidos, bem como no Mestrado em Medicina, Cirurgia e Implantodontia Oral do Hospital Odontológico da Universidade de Barcelona, entre julho de 2011 e março de 2016. Foram revisados 466 pacientes, com um total de 1405 implantes instalados, considerando o histórico oncológico dos pacientes e a taxa de sucesso do implante. Resultados: A taxa de sucesso total no período em questão foi de 96,65%. Na comparação entre pacientes com câncer e saudáveis, a taxa de sucesso foi de 93,02% no primeiro caso e 97,16% no segundo. Conclusão: De acordo com a revisão da literatura, nossos resultados encorajam a colocação de implantes em pacientes com câncer, é importante reconhecer que esta é uma análise complexa que requer cuidado devido ao grande número de variáveis. No entanto, os resultados não devem ser considerados de forma generalizada.

Estudio in vitro de la erosión dental asociada al chimó / In vitro study of dental erosion associated to Chimo

Antecedentes: Chimó es el nombre en Venezuela de una sustancia viscosa de color negruzco, cuyo componente principal deriva de la hoja de tabaco. Su consumo se ha asociado a alteraciones sistémicas y patologías bucales. Objetivo: Identificar in vitro la erosión dental asociada a exposición al chimó. Métodos: Se seleccionaron 30 dientes, 10 control negativo, 10 control positivo y 10 grupo experimental que se expusieron a soluciones de saliva artificial, Coca-Cola® light y chimó respectivamente, durante 20 semanas. Se analizó clínicamente la superficie y el análisis ultraestructural se efectuó con microscopio electrónico de barrido. Resultados: Clínicamente, se evidenció cambio de color en el grupo control negativo; cambio de color y superficial y pérdida de brillo en el grupo control positivo; y cambio de color y superficial en el grupo experimental (p = 0,000). El análisis ultraestructural indica que el grupo control negativo no presentó alteraciones morfológicas en la superficie del esmalte. En la escala de valores de grabado ácido utilizada, el grupo control positivo fue tipo 4 y el grupo experimental mostró estructura adamantina erosionada con imágenes similares a los patrones de grabado tipo 3-4. En cuanto a la clasificación según su gravedad, el grupo experimental correspondió al grado 1, con pérdida de esmalte sin involucrar dentina. Conclusión: En las condiciones experimentales de este estudio, el chimó produjo pérdida de la superficie del esmalte tanto clínica como ultraestructuralmente, con patrones de erosión tipos 3 y 4 de la escala de valores del grabado ácido y grado 1 según su gravedad.

Background: In Venezuela, chimó is a blackish goo derived from tobacco leaf. Its consumption has been associated with systemic and oral diseases. Purpose: To identify in vitro dental erosion associated to chimó exposure. Methods: The sample consisted of 30 teeth that were assigned 10 to the negative control group, another 10 to the positive control group, and 10 to the experimental group, which were exposed respectively to artificial saliva, Coca-Cola® light, and chimó for 20 weeks. Tooth surfaces were analyzed clinically and structurally, the latter through scanning electron microscope. Results: Clinical observations showed surface color change in the negative control group; color change and surface gloss loss in the positive control group; color and surface changes in the experimental group (p = 0.000). Ultrastructural analysis showed no enamel surface alterations in the negative control group. Acid etching scale values were 4 for the positive control group and 3-4 for the experimental group. The latter had signs of enamel erosion. In terms of severity of damage, the experimental group was type 1, that is, enamel loss without involving dentin. Conclusion: Under these experimental conditions, chimó caused clinical and ultrastructural enamel surface loss with type 3-4 erosion patterns, and type 1 severity.

A literature review and case report of hand, foot and mouth disease in an immunocompetent adult.

BACKGROUND: To report an uncommon case of hand, foot and mouth disease, (HFMD) in an immunocompetent adult; a highly infectious disease, characterized by the appearance of vesicles on the mouth, hands and feet, associated with coxsackieviruses and enteroviruses; including a literature review. CASE REPORT: A 23 year Caucasian male with no medical or surgical history, no allergies, was not taking any medication and smoked ten cigarettes a day, suffering from discomfort in the oral cavity; itching, burning and pain when swallowing associated with small erythematous lesions located on the hard palate, and small ulcers in tonsillar pillars and right buccal mucosa. Mild fever of 37.8 °C and general malaise. The patient reported he had had contact with a child diagnosed with HFMD. From his background and symptoms, the patient was diagnosed with HFMD. Following symptomatic treatment, the symptoms remitted in 7 days. METHODS: A literature review in MEDLINE (PubMed). The inclusion criteria were for studies on humans over the last 5 years, using the keywords HFMD. RESULTS: We found 925 articles, which were subsequently reduced to 52 documents after applying the inclusion criteria. Maculopapular lesions were found on hands and feet. CONCLUSIONS: Dentists may have a key role diagnosing the disease. A surveillance system to predict future outbreaks, encourage early diagnosis, put appropriate public health measures in place and research vaccine development is vitally important in order to control the disease.

Effectiveness of dentist's intervention in smoking cessation: A review.

INTRODUCTION: Smoking is one of the main public health problems in developed countries. Despite extensive evidence on the effects of smoking on both oral and general health, the rate of smoking cessation is not promising. MATERIAL AND METHODS: To review the evidence on knowledge and programs for smoking cessation developed by dentists, a literature review was carried out on programs for smoking cessation from the dentist's perspective, as well as a review of behavioral guidelines that have been recently proposed for these interventions. We used the keywords "Tobacco", "Smoking Prevention", "Public Health" AND "Dentistry", to identify controlled studies, systematic reviews and meta-analyses published between 1999 and 2014, in Google Scholar, SCOPUS and PubMed. RESULTS: Out of 177 studies found, 35 were considered, and these were divided into 2 groups of 20 and 15 articles respectively, according to type of study and inclusion criteria. CONCLUSIONS: There is considerable scientific evidence describing the programs for smoking cessation used in dentistry, which support their effectiveness. Overall, these are brief behavioral interventions complemented by pharmacological treatment, with the participation of the entire dental team. KEY WORDS: Dentistry, nicotine, smoking cessation, tobacco.

Precáncer y cáncer bucal / Oral precancer and cancer

Se revisa el concepto de lesiones precancerosas orales, de cáncer oral y su diagnóstico precoz. Con las palabras clave: premalignant oral lesions prevention se realiza una búsqueda de los 10 últimos años. También se buscan los ensayos clínicos desde enero de 2011 hasta la actualidad con las palabras clave: oral cancer prevention AND dentistry. Se destaca que no hay cambios significativos relacionados con el concepto de lesión precancerosa y cáncer, y que en cuanto al diagnóstico precoz, si bien se describen numerosos métodos de cribado, la biopsia sigue siendo la prueba más útil y, por tanto, imprescindible, más aún si consideramos las nuevas posibilidades de estudios moleculares (AU)

We reviewed the concept of oral precancerous lesions, oral cancer, and the possibility of early diagnosis. With the keywords: premalignant oral lesions prevention, a search was performed over the past 10 years. Also clinical trials are searched from January 2011 until today with the keywords: oral cancer prevention AND dentistry. It is emphasized that there can be no significant changes related to the concept of precancerous lesions and cancer, and those relating to the early diagnosis. Despite the numerous described methods of screening, biopsy remains the most useful test, and therefore it is essential, mainly if we consider the new possibilities of molecular studies (AU)
