The importance of the presence of aggregatibacter actinomycetemcomitans in sulcus gingivalis of patients with cardiovascular diseases.
(5/13)
BACKGROUND: Over-replication of periodontal pathogens in the periodontium induces production of proinflammatory cytokines and C-reactive protein that can stimulate systemic inflammatory status and can initiate atherosclerosis and its consequences. In our pilot study we examined whether periodontal status and serum levels of interleukin-6 and C-reactive protein are associated with the presence of Aggregatibacter actinomycetemcomitans in the periodontium of patients with cardiovascular diseases (CVD). MATERIAL/METHODS: We randomly selected 38 of 166 outpatients with CVD, of which 21 patients had chronic ischemic heart disease (IHD) only and 17 had both IHD and essential hypertension (HT). The presence of Aggregatibacter actinomycetemcomitans (A.a.) in the periodontium evaluated by PCR was compared with the values of periodontal indices, namely probe depth (PD) and Community Periodontal Index of Treatment Need (CPITN), as well as with interleukin-6 (IL-6) and CRP serum levels. RESULTS: When comparing A.a.-positive and A.a.-negative groups of patients, no statistically significant differences were noticed as to the age and values of PD and CPITN, respectively. However, the proportion of CRP and IL-6 positive values was significantly higher (p +info)

Orthodontic treatment need in a Spanish young adult population.
(7/13)
OBJECTIVES: Orthodontic treatment need has often been assessed in child populations, but few studies employing internationally-recognized indices have been conducted in adult or young adult populations. The aim of this study was to determine the orthodontic treatment need of a young adult population in Spain by means of the Dental Aesthetic Index (DAI), the Index of Orthodontic Treatment Need (IOTN) and the need perceived by the patients. STUDY DESIGN: A cross-sectional epidemiological study was conducted in a broad, representative sample of 671 adults aged between 35 and 44 years using health centers in the Valencia Region of Spain, following the recommendations of the World Health Organization (WHO). RESULTS: Orthodontic treatment was required by 31.3% of the sample according to the DAI and 19.2% according to the IOTN (DHC). The orthodontic treatment need perceived by the patients was 21.1%. On relating treatment need to different variables, significant differences in patient perception were encountered by gender, as women perceived a greater need (23.9%) than men (14.4%). Significant differences in previous orthodontic treatment history were found between middle/high (15%) and low (9%) social class and between secondary/tertiary (14%) and primary (3.3%) education. CONCLUSIONS: There was no agreement between the treatment need assessed objectively by the indices and that perceived by the patient, or between the indices themselves. The decision to undergo orthodontic treatment can depend on socioeconomic and psychological factors and on values and principles that do not easily lend themselves to objective measurement. (+info)
