Sensibilidad y especificidad de un índice de higiene oral de uso comunitario

Abstract

SUMMARY Introduction: Indexes of oral hygiene and dental plaque measurements have been developed since the 1960s in assessing an individual's oral hygiene, and to evaluate the effectiveness of programs to promote oral health and to measure the effectiveness of therapeutic methods. The Dental School at Universidad del Valle and the Pacifico Siglo XXI research team have developed an oral hygiene index for community use and evaluate its sensitivity and specificity versus three other indexes used in studies worldwide. Methodology: A group of seven students in their fifth year of dentistry were standardized for the registration of pattern indexes (gold standard), the OLeary index, detritus index by Greene & Vermillion index, Silness & Loe index, and the oral hygiene index for community use (CPI) achieving a match with Kappa values from 0.83, 0.81, 0.71, 0.94, and 0.86, respectively. A total of 83 fifth grade, primary school children were examined with parental consent; the data was recorded and taken to a database that was processed with a SSPS version 17 program. Results: The plaque rate in the children evaluated was 80%. No significant differences were found between the gold standard, the Oleary index, and the oral hygiene index for community use. The sensitivity of the indices evaluated was: 96.8 (95% CI 95.5-97.9) for the O'Leary index; 95.1 (95% CI 92.5-97.4) for the CPI; 75.2 (95% CI: 73.1-77.1) Greene &
