RESUMO

AIM: To identify toothbrushing patterns among schoolchildren with no prior dental hygiene training and associate them with effectiveness for eliminating dental biofilm. MATERIALS AND METHODS: Eight calibrated dentists assessed dental biofilm, toothbrushing procedure and dental status and registered: grip, bristle angle with respect to tooth, type of movement, surfaces brushed, simultaneous brushing of both jaws, including all six sextants and duration of brushing dental biofilm before and after brushing was determined in 944 children. Frequency distribution was calculated for nominal variables and central tendency and dispersion for quantitative variables of the toothbrushing procedure. Effectiveness was evaluated in 236 children by calculating differences between biofilm levels before and after brushing using Student's test. A cutoff value was established for the difference in reductions in biofilm levels by means of an ROC curve. RESULTS: The variables including all 6 sextants and bristle angle showed positive association with biofilm reduction. The cutoff point for biofilm reduction for including all 6 sextants was 66.85% (OR 6.4 [3.6-11.38]). The cutoff value for biofilm reduction for bristle angle was 68.35% (OR 3.2 [1.83-5.8]). CONCLUSION: The variables associated with biofilm reduction can be used to optimize the modality of future educational interventions in schoolchildren.

RESUMO

The aim of this study was to establish the association between features regarding brushing procedure performed by schoolchildren without previous formal training and the effectiveness of biofilm removal. Out of a population of 8900 6- and 7-year-old schoolchildren in Buenos Aires City, 600 children were selected from schools located in homogeneous risk areas. Informed consent was requested from parents or guardians and formal assent was obtained from children themselves. The final sample consisted of 316 subjects. The following tooth brushing variables were analyzed: toothbrush-gripping, orientation of active part of bristles with respect to the tooth, type of movement applied, brushing both jaws together or separately, including all 6 sextants and duration of brushing. The level of dental biofilm after brushing was determined by O'Leary's index, acceptable cut-off point = 20%. Four calibrated dentists performed observations and clinical examinations. Frequency distribution, central tendency and dispersion measures were calculated. Cluster analyses were performed; proportions of variables for each cluster were compared with Bonferroni's correction and OR was obtained. The most frequent categories were: palm gripping (71.51%); perpendicular orientation (85.8%); horizontal movement (95.6%); separate addressing of jaws (68%) and inclusion of all 6 sextants (50.6%). Mean duration of brushing was 48.78 ± 27.36 seconds. 42.7% of the children achieved an acceptable biofilm level. The cluster with the highest proportion of subjects with acceptable post-brushing biofilm levels (p<0.05) differed significantly from the rest for the variable "inclusion of all 6 sextants in brushing procedure". OR was 2.538 (CI 95% 1.603 - 4.017). Inclusion of all six sextants could be a determinant variable for the removal of biofilm by brushing in schoolchildren, and should be systematized as a component in oral hygiene education.


El objetivo del trabajo fue establecer la asociación entre las características del procedimiento de cepillado en escolares sin previo entrenamiento formal con la efectividad para el barrido del biofilm dental. Sobre una población de 8900 escolares de Ciudad Autónoma de Buenos Aires de 6 y 7 años de edad, se seleccionaron 600 niños concurrentes a escuelas situadas en áreas de riesgo homogéneo. Sobre esta muestra se solicito consentimiento informado a los responsables legales y el asentimiento formal, conformando una muestra final de 316 individuos. Se analizaron las siguientes variables del procedimiento de cepillado: tipo de toma del cepillo dental, orientación de la parte activa respecto del diente, tipo de movimiento aplicado, abordaje simultaneo o no de ambos maxilares, inclusión de los 6 sextantes y duración de cepillado. El nivel de biofilm dental posterior al cepillado se determinó con el índice de O'Leary-punto de corte aceptable=20%. Cuatro odontólogos calibrados realizaron las observaciones y exámenes clínicos. Se calculó: distribución de frecuencias, medidas de tendencia central y su dispersión. Se realizó un análisis de clúster y comparación de proporciones de las variables de cada conglomerado con corrección de Bonferroni y OR. Las categorías más frecuentes fueron: toma palmar (71,51%); orientación perpendicular (85,8%); movimiento horizontal (95,6%); cepillado de ambos maxilares por separado (68%) e inclusión de los 6 sextantes (50,6%).La media de duración del cepillado fue de 48.78 ± 27.36 segundos. El42,7 % de los escolares alcanzaron un nivel de biofilm aceptable. El clúster que mostró la mayor proporción de individuos con niveles de biofilm postcepillado aceptables (p<0,05) mostró diferencias estadísticamente significativas con los demás respecto de la variable "inclusión de 6 sextantes en el cepillado". El OR fue igual a 2,538 (IC 95% 1,603 ­ 4,017). La inclusión de los seis sextantes podría ser una variable determinante de la efectividad del barrido de biofilm mediante el cepillado en escolares debiendo enfatizarse la sistematización del mismo como componente de la enseñanza de higiene bucal.
