Association between subjects with newly Diagnosed rheumatoid arthritis and dental caries / Asociación entre sujetos con artritis reumatoide recientemente diagnosticada y caries dental

Abstract Alterations in saliva, temporomandibular joint disorders, dysphagia, Sjogrens syndrome, dental caries, periodontal disease, and tooth loss have been identified in patients with Rheumatoid Arthritis. The aims of this research were 1) to study the association between newly diagnosed rheumatoid arthritis and dental caries and 2) to identify most frequent teeth with caries in study groups. A descriptive pilot study was performed. A total of 620 participants were evaluated, 29 met the selection criteria. The subjects were divided into 2 groups: 13 subjects with newly diagnosed rheumatoid arthritis and 16 subjects without rheumatoid arthritis. Salivary parameters, DMFT index, care index, FS-T index and Treatment Needs Index were evaluated in all participants. The Fishers Exact test and Mann-Whitney U test we used to establish the differences between groups. Low mean in all salivary parameters and a high caries frequency were observed in subjects with newly diagnosed rheumatoid arthritis compared to a control group (p<0.01). The right maxillary second premolar (n=6, 46%, p=0.0100); right mandibular second premolar (n=7,54%, p=0.0462) and left mandibular second molar (n=10,77%, p=0.0001) were the most frequent teeth with caries. Early diagnosis and early treatment of rheumatoid arthritis can improve the prognosis in most of patients. The development of new public health policies and care based on the prevention are necessary to improve the quality of patients lives.

Resumen Alteraciones en la saliva, trastornos de la articulación temporomandibular, disfagia, síndrome de Sjogren, caries dental, enfermedad periodontal y pérdida de dientes son algunas patologías que se han identificado en pacientes con artritis reumatoide. Los objetivos de este estudio fueron (1) Asociar la artritis reumatoide recientemente diagnosticada con la caries dentales e (2) Identificar los dientes más frecuentes con caries en los grupos de estudio. Se realizó un estudio piloto descriptivo. 620 participantes fueron evaluados, 29 sujetos cumplieron con los criterios de selección. Los sujetos se dividieron en 2 grupos: 13 sujetos con artritis reumatoide recién diagnosticados y 16 sujetos sin artritis reumatoide. En todos los participantes se evaluaron parámetros salivales, el índice CPOD, el índice IC, el índice FS-T y el índice INT. La prueba exacta de Fisher y U de Mann-Whitney se utilizaron para establecer diferencias entre grupos. En los resultados se observó un bajo promedio de los parámetros salivales y una alta frecuencia de caries en sujetos con artritis reumatoide recién diagnosticados comparados con un grupo control (p<0.01). El segundo premolar superior derecho (n=6,46%, p=0,0100); el segundo premolar mandibular derecho (n=7,54%, p=0.0462) y el segundo molar mandibular izquierdo (n=10,77%, p=0.0001) fueron los dientes más frecuentes con caries dental. El diagnóstico y el tratamiento temprano de la artritis reumatoide pueden mejorar el pronóstico en la mayoría de los pacientes. El desarrollo de nuevas políticas de salud pública basadas en la prevención de la cavidad bucal son necesarias para mejorar la calidad de vida de los pacientes.

Association between periodontitis, periodontopathogens and preterm birth: is it real?

PURPOSE: To identify the association between periodontitis and periodontal pathogens with preterm birth despite the strict control of some important confounders, such as infectious processes and criteria for diagnosis of periodontitis during pregnancy. MATERIALS AND METHODS: In this cross-sectional study were included 70 healthy puerperal women between 20 and 35 years without a history of genitourinary infections during pregnancy. Based on the gestational age they were divided into two groups: 45 with term birth (>37 weeks) and 25 with preterm birth (<37 weeks). Previous informed consent, a gynecologic and dental history that included gynecologic and obstetric background, periodontal status applying different authors' criteria of periodontitis diagnosis, presence of periodontopathogens, dental caries and oral hygiene were recorded. RESULTS: There was no association between periodontitis, periodontopathogens and preterm birth. There were no statistical differences applying different authors' criteria diagnosis of periodontitis. Gingivitis status was similar, but probing depth was greater in preterm birth subjects, perhaps they are young women, and this finding could be an early sign of periodontitis. In like manner, the main periodontal bacterial species are not associated with preterm birth, general hygiene and care habits are poorer than term birth subjects. CONCLUSION: We could suggest that preterm birth is a multifactorial condition and the role of periodontitis and the periodontopathogens itself is not sufficient to trigger the preterm birth. There are factors such as infectious processes and diagnostic criteria for periodontitis that could be responsible for controversial results.
