Comparison between two different local hemostatic methods for dental extractions in patients on dual antiplatelet therapy: a within-person, single-blind, randomized study.

BACKGROUND: Dual antiplatelet therapy (DAPT) provides additional risk reduction of ischemic events compared to aspirin monotherapy, at cost of higher bleeding risk. There are few data comparing new techniques for reducing bleeding after dental extractions in these patients. PURPOSE: This study investigated the effectiveness of the HemCon Dental Dressing (HDD) compared to oxidized cellulose gauze. MATERIALS AND METHODS: This randomized study included 60 patients on DAPT who required at least two dental extractions (120 procedures). Each surgical site was randomized to HDD or oxidized regenerated cellulose gauze as the local hemostatic method. Intra-oral bleeding time was measured immediately after the dental extraction and represents our main endpoint for comparison of both hemostatic agents. Prolonged bleeding, platelet reactivity measured by Multiplate Analyser (ADPtest and ASPItest) and tissue healing comparison after 7 days were also investigated. RESULTS: Intra-oral bleeding time was lower in HDD compared with control (2 [2-5] vs. 5 [2-8] minutes, P=0.001). Prolonged postoperative bleeding was observed in 7 cases (11.6%), all of them successfully managed with local sterile gauze pressure. More HDD treated sites presented better healing when compared with control sites [21 (36.8%) vs. 5 (8.8%), P=0.03]. There was poor correlation between platelet reactivity and intra-oral bleeding time. CONCLUSIONS: In patients on DAPT, HDD resulted in a lower intra-oral bleeding time compared to oxidized cellulose gauze after dental extractions. Moreover, HDD also seems to improve healing conditions.

Favorable Safety Experience of Local Dental Anesthesia in ICD Recipients with Cardiac Channelopathies

Abstract Background Dental anesthetic management in implantable cardioverter defibrillator (ICD) recipients with cardiac channelopathies (CCh) can be challenging due to the potential risk of life-threatening arrhythmias and appropriate ICD therapies during procedural time. Objectives The present study assessed the hypothesis that the use of local dental anesthesia with 2% lidocaine with 1:100,000 epinephrine or without a vasoconstrictor can be safe in selected ICD and CCh patients, not resulting in life-threatening events (LTE). Methods Restorative dental treatment under local dental anesthesia was made in two sessions, with a wash-out period of 7 days (cross-over trial), conducting with a 28h - Holter monitoring, and 12-lead electrocardiography, digital sphygmomanometry, and anxiety scale assessments in 3 time periods. Statistical analysis carried out the paired Student's t test and the Wilcoxon signed-rank test. In all cases, a significance level of 5% was adopted. All patients were in stable condition with no recent events before dental care. Results Twenty-four consecutive procedures were performed in 12 patients (9 women, 3 men) with CCh and ICD: 7 (58.3%) had long QT syndrome (LQTS), 4 (33.3%) Brugada syndrome (BrS), and 1 (8.3%) Catecholaminergic polymorphic ventricular tachycardia (CPVT). Holter analysis showed no increased heart rate (HR) or sustained arrhythmias. Blood pressure (BP), electrocardiographic changes and anxiety measurement showed no statistically significant differences. No LTE occurred during dental treatment, regardless of the type of anesthesia. Conclusion Lidocaine administration, with or without epinephrine, can be safely used in selected CCh-ICD patients without LTE. These preliminary findings need to be confirmed in a larger population with ICD and CCh.

Demographic, cardiological, microbiologic, and dental profiles of Brazilian patients who developed oral bacteria-related endocarditis.

OBJECTIVE: Infective endocarditis (IE) may cause devastating complications with high morbidity and mortality rates. The aim of the present study was to study the demographic, cardiological, microbiologic, and dental profiles of patients with oral bacteria-related IE. STUDY DESIGN: We present a retrospective study of patients with oral bacteria-related IE treated at Instituto do Coração, Hospital das Clínicas, Faculdade de Medicina, Universidade de Sao Paulo, Brazil, between January 2009 and December 2019. RESULTS: Of the 100 patients included, 70% were male with a mean age of 45.4 years at diagnosis. The most affected sites were aortic and mitral valves, 60% in prosthetic heart valves, 34% in native valves, and 3% in pacemakers. The most common cause of valvular disease was rheumatic cardiopathy (51.9%), and the most frequent complications were valvular and perivalvular damage (26%). Streptococcus viridans was the most common species (96%), dental caries were present in 57% of the patients, 78% had tooth loss, 45% had apical periodontitis, and 77% were at high/moderate risk for periodontal disease. CONCLUSION: Oral bacteria-related IE among Brazilians was predominant in the prosthetic heart valves of young male adults previously affected by rheumatic cardiopathy. Streptococcus viridans was the main cause of IE, which was linked to patients with a poor oral health status.

Local anesthesia with epinephrine is safe and effective for oral surgery in patients with type 2 diabetes mellitus and coronary disease: a prospective randomized study.

OBJECTIVE: To investigate the variations in blood glucose levels, hemodynamic effects and patient anxiety scores during tooth extraction in patients with type 2 diabetes mellitus T2DM and coronary disease under local anesthesia with 2% lidocaine with or without epinephrine. STUDY DESIGN: This is a prospective randomized study of 70 patients with T2DM with coronary disease who underwent oral surgery. The study was double blind with respect to the glycemia measurements. Blood glucose levels were continuously monitored for 24 hours using the MiniMed Continuous Glucose Monitoring System. Patients were randomized into two groups: 35 patients received 5.4 mL of 2% lidocaine, and 35 patients received 5.4 mL of 2% lidocaine with 1:100,000 epinephrine. Hemodynamic parameters (blood pressure and heart rate) and anxiety levels were also evaluated. RESULTS: There was no difference in blood glucose levels between the groups at each time point evaluated. Surprisingly, both groups demonstrated a significant decrease in blood glucose levels over time. The groups showed no significant differences in hemodynamic and anxiety status parameters. CONCLUSION: The administration of 5.4 mL of 2% lidocaine with epinephrine neither caused hyperglycemia nor had any significant impact on hemodynamic or anxiety parameters. However, lower blood glucose levels were observed. This is the first report using continuous blood glucose monitoring to show the benefits and lack of side effects of local anesthesia with epinephrine in patients with type 2 diabetes mellitus and coronary disease.

Peripheral oxygen saturation, heart rate, and blood pressure during dental treatment of children with cyanotic congenital heart disease.

OBJECTIVES: In this observational study, we evaluated the peripheral oxygen saturation (SpO2), heart rate, and blood pressure of children with cyanotic congenital heart disease who were undergoing dental extraction. METHODS: Forty-four patients between the ages of 6 and 12 years who underwent upper primary tooth extraction were included in the study. Of these, 20 patients were in the cyanotic congenital heart disease group and 24 were in the control group. RESULTS: Peripheral oxygen saturation, heart rate, and systolic blood pressure in the cyanotic congenital heart disease group varied quite significantly during the treatment protocol (p<0.05), with values of 80.5% (±7.6) to 82.8% (±7.8), 95.3 beats per minute (bpm) (±11.3) to 101.3 bpm (±9.8), and 93.6 mm Hg (±13,3) to 103.8 mm Hg (±12.7), respectively. The variations in the control group during the procedure were also significant. CONCLUSIONS: The changes observed during the study protocol, although statistically significant, were mild and lacked clinical relevance. The results indicate that dental treatment of children with cyanotic heart disease using a standardized protocol in decentralized offices without the support of a surgical center is safe.

Perfil da saúde bucal de crianças e adolescentes submetidos ao transplante cardíaco - estudo piloto / Profile of the oral health of children and adolescents undergoing heart transplantation - pilot study

O transplante cardíaco é considerado a última opção no tratamento de insuficiência cardíaca terminal, miocardiopatias e cardiopatias congênitas, esgotadas as possibilidades cirúrgicas e/ou medicamentosas. Nos últimos anos, o transplante cardíaco infantil tem demonstrado grande desenvolvimento e avanços importantes clínica e cientificamente. Os quadros de rejeição representam a principal causa de morbidade e mortalidade, no primeiro ano pós-transplante. Visando reduzir a taxa de morbidade e mortalidade, uma terapia imunossupressora é instituída. Entretanto, efeitos colaterais importantes estão relacionados à terapia imunossupressora, dentre eles efeitos extraorais e intraorais. É sabido que a má saúde bucal, associada à terapia imunossupressora, promove doenças bucais, bem como aumenta o risco às infecções secundárias. Por isso, o objetivo deste estudo constou de identificar o perfil de saúde bucal de crianças e adolescentes submetidos ao transplante cardíaco nesta instituição, encaminhados rotineiramente à Unidade de Odontologia pela Unidade de Congênitos. Vinte pacientes foram submetidos à entrevista sobre sua percepção de saúde bucal, avaliação da saúde bucal, por meio de questionários e de índices odontológicos. Este estudo evidenciou que a maioria dos pacientes avaliados (98%) realiza acompanhamento odontológico constante e a percepção destes aponta sua saúde bucal como sendo boa. Os índices odontológicos mostram baixo valor de CPO-D(0,1) e CEO-D(0,05) e baixo índice de gengivite, apesar do alto índice de placa (66%), deixando bem clara a importância da atuação do cirurgião-dentista como parte integrante da equipe multiprofissional, no tratamento, acompanhamento e manutenção dos pacientes submetidos ao transplante cardíaco.

The cariac transplantation has been considered the last treatment option for terminal heart failure, cardiomyopathies and congenital heart disease, without any drug or surgical possibilities, Lately, the infant heart transplantation has shown great development and importante clinical and scientific advances. The rejection cases represent the major cause of morbidity and mortality, during the first year post-transplant. In order to reduce the morbidity and mortality index, na immunosuppressive therapy is instituted, However, importante side effects are related to the immunosuppressive therapy, among them are extra-oral and intra-oral effects. It's known that poor oral ealth, associated with the immunosuppressive therapy promote oral disease, as well as increasing the risk to of identifying the oral health status of children and adolescentes undergoing cardiac transplantation, referred routinely to the Unit of Dentistry from the Congenital Unit. Twenty patients underwent na interview about their own oral health perception, evaluation of oral changes resulting from immunosuppressive therapy and oral health evalution, using questionnaires and dental índices. This study showed that most patients (98%) performed constatnt dental monitoring and this perception points their oral health as being good. The dental índices showed low values of DMFT (0,1) and deft (0,05) and low level of gingivitis, despite the high rate of plaque (66%), makin vey clear the importance of the dentist's roel as part of the multidisciplinar team, in treatment, monitoring and maintenance of patients undeergoing heart transplantation.

Linfangioleiomiomatose: relato de caso / Lymphangioleiomyomatosis: case report

A Linfangioleiomiomatose (LAM) é uma doença sistêmica rara, de etiologia desconhecida, que afeta quase exclusivamente mulheres em idade reprodutiva. Caracterizada pela proliferação atípica de células musculares lisas em diversos órgãos, especialmente pulmão, que leva ao desenvolvimento de um distúrbio ventilatório obstrutivo, de caráter progressivo, com hiperinsuflação pulmonar e diminuição da difusão de monóxido de carbono, devido aos inúmeros cistos que formados no parênquima pulmonar. A manifestação clínica mais comumé o pneumotórax. O fator hormonal tem sido exposto como coadjuvante no desenvolvimento da doença, já que esta atinge quase que exclusivamente indivíduos do sexo feminino e se intensifica durante a gestação. Pesquisas recentes verificaram ao corrência de mutações genéticas e presença de lesões que estão associadas à doença Esclerose Tuberosa; porém, há necessidadede mais estudos para afirmar essa correlação. O presente relatorefere-se a paciente do sexo feminino, 45 anos de idade, brasileira,leucoderma, com diagnóstico de Linfangioleiomiomatose que compareceu ao ambulatório de Odontologia do Instituto do Coração do Hospital das Clínicas (FMUSP), encaminhada pelo Departamento de Pneumologia, para avaliação odontológica pré-operatória de transplante pulmonar. Paciente contactuante,com dispneia e uso contínuo de cateter de oxigênio, apresentando em cadeira de rodas para mínimo esforço físico. Higiene oral insatisfatória evidenciada pela presença de tártaro, raiz residual inaproveitável e lesões cariosas. Sabe-se que a infecção está entre as maiores causas de perda do órgão recebido pelo transplantado e, por isso, a atuação do cirurgião-dentista é de suma importância para prevenir quadros sistêmicos infecciosos decorrentes de focos bucais, pré e pós-transplante.

The Lymphangioleiomyomatosis (LAM) is a rare systemic disease of unknown etiology that affects mainly women atreproductive age. Characterized by an atypical proliferation of smooth muscle cells in various organs, especially in thelungs, which leads to the development of obstructive lung disease, a progressive character, with hyperinflation anddecreased lung diffusion of carbon monoxide due to the numerous cysts that are formed in the lung parenchyma.The most common clinical manifestation is pneumothorax. The hormonal factor has been exposed as an adjuvant in thedevelopment of the disease since it affects almost exclusively women and intensifies during pregnancy. Recent researches verified the occurrence of mutations and genetic lesions thatare associated with the disease Tuberous Sclerosis, but further studies are necessary in order to affirm this correlation. This report refers to a female patient, 45 years of age, Brazilian, leukoderma, diagnosed with Lymphangioleiomyomatosis who attended the outpatient clinic of Dentistry from the Heart Institute, Hospital das Clínicas (FMUSP) forwarded by the Department of Pulmonology, for a lung transplantpreoperative dental evaluation. Patient with dyspnea and continuous use of oxygen catheter, performing in a wheelchair for minimal physical effort. Poor oral hygiene evidenced by the presence of tartar, root caries and residual unusable. It is known that infection is among the biggest causes of loss of the transplanted organ by the receiver and, therefore, the role of the dentist is very important to prevent systemic frameworks infectious foci resulting from oral pre-andpost-transplant.

Importância do atendimento odontológico em pacientes portadores de marcapasso e cardiodesfibrilador implantãvel / Importance of dental care in patients with pacemaker and implantable defibrilator

A relação entre infecção orais, bacteremia e infecções sistêmicas é um fato já estabelecida. Entretanto, a afirmação de que os micro-organismos orais são responsáveis por infecções secundárias em dipositivos cardíacos, como marcapasso e cardiodesfibriladores implantáveis, ainda é pouco citada na literatura. Sabe-se que não só em procedimentos odontológicos invasivos pode ocorrer esse tipo de manifestação. Ações rotineiras, como mastigação e higienização oral. Também são passíveis de provocar bacteremia e mesmo a instalação de doenças. Alguns fatores, como a quantidade de bactérias que penetram na corrente sanguínea, bem como seu potencial de patogenicidade parecem estar relacionados a fatores locais, como presença de infecção oral (biofilme, cárie, doença periodontal, infecções orais agudas). O objetivo dessa revisão é abotrdar a presença de infecções a bacteremia em portadores de marcapasso e cardiodesfibrilador implantável e sua relação com micro- organismos presentes na cavidade oral. Os métodos utilizadps foram busacas em banco de dados eletrônicos, como LILACS e MEDLINE/PubMed, e inspeção manual dos artigos. Apesar do vasto acervo de relatos sobre a presença de infecções...

Terapia antiplaquetária e sangramento pós-exodontia / Antiplatelet therapy and post exodontia bleeding

Com o aumento da incidência de doenças cardiovasculares, agentes antiplaquetários têm sido prescritos com muita frequência para o tratamento e prevenção de eventos trombóticos. É cada vez mais frequentes o cirurgião-dentista se deparar com pacientes em uso profilático de antiagregantes plaquetários e a principal preocupação no atendimento destes pacientes é um maior sangramento após procedimentos odontológicos. Esses medicamentos promovem a inibição permanente da cicloxigenase, atuando na terapia antiagregante, o ácido acetilsalicílico (AAS) é amplamente indicado para a prevenção secundária de complicações decorentes de eventos trombo-embólicos, sendo a terapia padrão na prevenção dessas desordens. Existem questionamentos na literatura, quanto à suspensão do AAS antes de procedimentos cirúrgicos, uma vez que a interrupção da terapia antiagregante nesses pacientes aumenta o risco da ocorrência de eventos trombóticos.

Monitorização materno-fetal durante procedimento odontológico em portadora de cardiopatia valvar / Maternal-fetal monitoring during dental procedure in patients with heart valve disease / Monitoreo maternofetal durante procedimiento odontológico en portadora de cardiopatía valvular

FUNDAMENTO: Os efeitos da anestesia local em odontologia com lidocaína e epinefrina, sobre parâmetros cardiovasculares de gestantes portadoras de valvopatias e seus conceptos, não estão esclarecidos. OBJETIVO: Avaliar e analisar parâmetros da cardiotocografia, de pressão arterial e eletrocardiográficos da gestante portadora de doença valvar reumática, quando submetida à anestesia local com 1,8 ml de lidocaína 2 por cento sem vasoconstritor e com epinefrina 1:100.000, durante procedimento odontológico restaurador. MÉTODOS: Realizamos monitorização ambulatorial da pressão arterial, eletrocardiografia ambulatorial materna e cardiotocografia de 31 portadoras de cardiopatia reumática, entre a 28ª e 37ª semana de gestação, divididas em dois grupos conforme presença ou não do vasoconstritor RESULTADOS: Demonstrou-se redução significativa dos valores de frequência cardíaca materna nos dois grupos, durante o procedimento, quando comparado aos demais períodos (p < 0,001). Houve ocorrência de arritmia cardíaca em 9 (29,0 por cento) pacientes, das quais 7 (41,8 por cento) pertencentes ao grupo de 17 gestantes que recebeu anestesia com adrenalina. A pressão arterial materna não apresentou diferença quando comparamos períodos ou grupos (p > 0,05). O mesmo ocorreu (p > 0,05) com número de contrações uterinas, nível e variabilidade da linha de base e número de acelerações da frequência cardíaca fetal. CONCLUSÃO: O uso de 1,8 ml de lidocaína 2 por cento associado à adrenalina mostrou-se seguro e eficaz em procedimento odontológico restaurador durante a gestação de mulheres com cardiopatia valvar reumática.

BACKGROUND: The effects of local dental anesthesia with lidocaine and epinephrine on cardiovascular parameters of pregnant women with heart valve diseases and their fetuses are not fully understood. OBJECTIVES: To assess and analyze cardiotocographic, blood pressure and electrocardiographic parameters of pregnant women with rheumatic heart valve disease undergoing local anesthesia with 1.8mL of lidocaine 2 percent with or without epinephrine 1:100,000 during restorative dental treatment. METHODS: Maternal ambulatory blood pressure and electrocardiographic monitoring as well as cardiotocography of 31 patients with rheumatic heart disease were performed between the 28th and 37th week of gestation. The patients were divided into two groups, those with or without vasoconstrictor. RESULTS: A significant reduction in maternal heart rate was shown in both groups during the procedure in comparison with the other periods (p<0.001). Cardiac arrhythmia was observed in nine (29.0 percent) patients, of which seven (41.8 percent) were from the group of 17 pregnant women who received anesthesia plus epinephrine. No difference in maternal blood pressure was observed when periods or groups were compared (p>0.05). The same occurred (p>0.05) with the number of uterine contractions, baseline level and variability, and number of accelerations of fetal heart rate. CONCLUSION: The use of 1.8mL of lidocaine 2 percent in combination with epinephrine was safe and efficient in restorative dental procedures during pregnancy in women with rheumatic heart valve disease.

CONCLUSIÓN: El uso de 1,8 ml de lidocaína 2 por ciento asociado a la adrenalina se mostró seguro y eficaz en procedimiento odontológico restaurador durante la gestación de mujeres con cardiopatía valvular reumática.

Síndrome da Maquiagem e Kabuki e suas implicações na odontologia / Kabuki Make-up syndrome and dentistry implications

Um caso clínico de sindrome da maquiagem de kabuki é apresentado. Trata-se de síndrome rara, com prevalência entre 1:32.000 e 50.000 nascimentos. As implicações odontológicas estão principalmente associadas ao risco de endocardite infecciosa, uma vez que mais de 40 por cento dos pacientes apresentam alterações cardíacas congênitas. A presença de déficit cognitivo requer atenção especial, pois interfere na manutenção da saúde bucal. O conhecimento clínico dessa condição e de suas manifestações sistêmicas é importante para que conduta odontológica correta seja instituída.

Locoregional anesthesia for dental treatment in cardiac patients: a comparative study of 2% plain lidocaine and 2% lidocaine with epinephrine (1:100,000).

OBJECTIVES: This study analyzes hemodynamic changes in patients with cardiac valvular diseases submitted to dental treatment under local anesthesia containing epinephrine. METHODS: This randomized clinical trial was performed at the Dental Division of the Instituto do Coração do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (Brazil). Patients were separated into two groups with the help of an aleatory number table: 2% plain lidocaine (PL, n= 31) and 2% lidocaine with epinephrine (1:100,000) (LE, n= 28). Blood pressure, heart rate, oxygenation and electrocardiogram data were all recorded throughout the procedure. State and trait anxiety levels were measured. RESULTS: Fifty-nine patients were selected for the LE group (n=28), with an average age of 40.3 +/- 10.9, or for the PL group (n=31), age 42.2 +/- 10.3. No differences were shown in blood pressure, heart rate and pulse oximetry values before, during and after local anesthesia injection between the two groups. State and trait anxiety levels were not different. Arrhythmias observed before dental anesthesia did not change in shape or magnitude after treatment. Complaints of pain during the dental procedure were more frequent within the PL group, which received a higher amount of local anesthesia. CONCLUSION: Lidocaine with epinephrine (1:100,000) provided effective local anesthesia. This treatment did not cause an increase in heart rate or blood pressure and did not cause any arrhythmic changes in patients with cardiac valvular diseases.
