RESUMOObjetivo: Revisão sistemática do conhecimento atual sobre a associação entre diabetes melito (DM) e doença periodontal (DP) com ênfase na sua fisiopatogenia. Fonte de dados: Pesquisa bibliográfica, nos últimos cinco anos, através dos bancos de dados MEDLINE e LILACS, usando as palavras-chaves "diabetes mellitus", "periodontal disease" e "periodontitis". Síntese dos dados: Os tecidos periodontais são as estruturas bucais mais afetadas pelo DM. O DM predispõe ao desenvolvimento da DP, a qual leva ao descontrole glicêmico, o que ressalta a importância da relação bidirecional entre essas duas doenças. Vários mecanismos estão envolvidos na fisiopatologia da DP associada ao DM: produção de produtos de glicosilação avançada, deficiente resposta imune, herança de determinados polimorfismos genéticos, alterações dos vasos sanguíneos, tecido conjuntivo e composição salivar. Na fase inicial predominam a gengivite e periodontite. Se não detectados precocemente, esses problemas podem evoluir para doença periodontal avançada. Puberdade, maior duração da doença, mau controle metabólico e higiene bucal inadequada são fatores que contribuem para progressão e agressividade da DP. Conclusão: O melhor conhecimento dos mecanismos envolvidos na fisiopatogenia da DP associada ao DM auxiliará na instituição de medidas preventivas e terapêuticas precoces. É importante que médicos e dentistas orientem os pacientes com DM sobre a necessidade de bom controle glicêmico e higiene bucal adequada para minimizar os riscos de doença periodontal. Objective: Systematic review of present knowledge about the association between diabetes mellitus (DM) and periodontal disease (PD) with emphasis on their physiopathogenesis. Data sources: Bibliographic search through MEDLINE and LILACS databases, in the last five years, using the following descriptors: "diabetes mellitus", "periodontal disease", and "periodontitis". Summary of data: Periodontal tissues are the oral structures most affected by DM. DM predisposes to the development of PD, which leads to loss of glycemic control, which emphasizes the importance of the two-way relationship between these two diseases. Several mechanisms are involved in the physiopathology of PD associated with DM: production of advanced glycosilation products, deficient immune response, inheritance of certain genetic polymorphisms, alterations in blood vessels, conjunctive tissue and salivary composition. In the initial phase, gingivitis and periodontitis predominate. If not detected early, these problems can develop into advanced periodontal disease. Puberty, with its hormonal alterations, longer duration of the disease, poor metabolic control and inadequate oral hygiene are factors that contribute to PD progression and aggressiveness. Conclusion: Better knowledge about the mechanisms involved in the physiopathogenesis of PD associated with DM would help to institute early preventive and therapeutic measures. It is important for doctors and dentists to instruct their patients with DM about the need for good glycemic c...
This study evaluated the oral health knowledge and habits in Brazilian children with type 1 diabetes mellitus (T1DM). A cross-sectional study was performed between November of 2005 and April of 2006 in a public health university hospital, interviewing 55 diabetic children and 55 non-diabetic control children with a semi-structured questionnaire. As much as 55% of the diabetic children and 35.5% of the non-diabetic children were males with mean age of 11.3 ± 3.7 years and 11.2 ± 3.8 years, respectively. The mean duration of the T1DM was of 4.5 ± 0.8 years. Almost half of the diabetic and non-diabetic children brushed their teeth three times a day. Dental floss was used once a day by 30.9% of diabetics and 18.0% of control subjects. A total of 27% of the diabetics vs. 54.5% of non-diabetics had gingival bleeding. The dentist was aware of the T1DM in 74.5% of the cases. As much as 63.8% of the diabetic subjects had been to the dentist within the previous 12 months. In conclusion, although the diabetic children seemed to have better oral health habits than the control children, there is a need for more information regarding oral hygiene and healthy habits.
The evaluation of the salivary flow rate is important in several situations of dental practice. However, weighing the collected salivary volume it is not a practical method in public health services. This work evaluated the use of hypodermic graduated syringes as a simpler alternative method to measure the salivary flow rate. Saliva samples were obtained from 50 individuals (31 females and 19 males) aged 8 to 32 years (mean age: 12.4 years), recruited at the outpatient dental clinics of two public health centers. After collection, the saliva was weighed in a graduated scale and the results compared with the volume obtained through its measurement, in mL, in graduated hypodermic syringes. There was a positive and significant relationship between the two methods of measuring salivary flow rates as demonstrated by the Pearson's correlation coefficient (r = 0.996, with p<0.05). Measurement of the salivary flow rate using graduated syringes demonstrated to be a reliable method, with lower cost and more practical than the traditional method of salivary weighing.
ResumoDiabetes melito (DM) abrange um grupo de distúrbios metabólicos que têm em comum a presença de hiperglicemia. Além das manifestações sistêmicas, o DM mal controlado apresenta importantes repercussões sobre a saúde oral (e.g., doença periodontal, xerostomia, hiposalivação, susceptibilidade a infecções, dificuldade de cicatrização). Este trabalho tem por objetivo destacar a importância do conhecimento básico do odontologista sobre DM e propor um protocolo de atendimento dentário para esses pacientes. A revisão bibliográfica foi realizada nos bancos de dados MEDLINE e LILACS, com pesquisa em artigos publicados nos últimos dez anos, a partir das palavras-chave: diabetes mellitus, dentistry, oral health e periodontal disease. Os resultados são estruturados em tópicos. Na primeira parte, são atualizadas informações sobre diagnóstico, manifestações clínicas, repercussões orais e tratamento do DM. Na segunda parte, propomos um protocolo de atendimento, no qual são discutidas, de modo didático (e.g., anamnese, exame físico, exames complementares, conduta), as dúvidas mais comuns em relação à consulta odontológica do diabético (e.g., profilaxia antibiótica em procedimentos com risco de bacteremia, uso de antiinflamatórios, sedativos e anestésicos com vasoconstrictores, tratamento paliativo versus definitivo, como proceder em casos de hipoglicemia e hiperglicemia, quando suspeitar de um DM não diagnosticado). Ao final, uma ficha clínica sumariza os principais aspectos da consulta odontológica do paciente diabético. Conclui-se que diabéticos bem controlados e sem complicações podem ser tratados de modo similar a não-diabéticos, para a maioria dos procedimentos de rotina. O cirurgião-dentista, em comunicação com o médico assistente, desempenha um importante papel na promoção e manutenção do bem-estar e qualidade de vida do paciente diabético.
