About

Malnutrition is a public health problem that can exert a negative impact on the general and oral health of children. The aim of the present study was to evaluate the effect of chronic malnutrition on the oral health of children aged one to five years. An observational, analytical, cross-sectional study was conducted at the Nutritional Recovery Center and involved 82 children between 12 and 71 months of age. Nutritional status was evaluated using anthropometric indicators and oral health status was measured using the dmft index. Non-stimulated saliva was collected. Flow rate and buffering capacity was then measured with the aid of a pH meter.

Full description

Malnutrition is a public health problem that can exert a negative impact on the general and oral health of children. The aim of the present study was to evaluate the effect of chronic malnutrition on the oral health of children aged one to five years. An observational, analytical, cross-sectional study was conducted at the Nutritional Recovery Center and involved 82 children between 12 and 71 months of age. Nutritional status was evaluated using anthropometric indicators. The children were weighed on a previously calibrated electronic scale (capacity: 150 kg; precision: 100 g) barefoot and wearing light clothing in the presence of the mother or caregiver. Height was determined using a non-flexible metric tape (maximum length: 2 m; precision: 0.1 cm). Each measurement was made twice and the mean was used for the calculation height for age, weight for height and weight for age. The guidelines of the World Health Organization, were the reference for the evaluation of nutritional status. Oral health status was measured using the dmft index. The criteria adopted for the determination of prevalence followed by guidelines of the Oral Health Surveys - Basic Methods, 4th edition - described in the examiner's manual and annotator's manual produced by the coordination team of the Brazil Oral Health Project. Non-stimulated saliva was collected and Flow rate and buffering capacity was then measured with the aid of a pH meter. The salivary flow volume was calculated and expressed as ml/min. The following categories were considered in the analysis of salivary flow: < 0.1 ml/min = xerostomia; 0.1 to 0.6 ml/min = very low flow; 0.7 to 0.9 mL/min low flow; 1.0 to 2.0 ml/min = normal flow; and > 2.0 ml/min = high flow. The following categories were considered: ≥ 5.5 = very good buffering capacity; 5.4 to 5.0 = good buffering capacity; 4.9 to 4.5 = medium good buffering capacity; 4.4 to 4.0 = low buffering capacity; and ≤ 3.9 very low buffering capacity.

Trial design

82 participants in 4 patient groups

Adequate nutritional status
Description:
Dental caries experience was recorded using the dmft index. Active visible white spots were also recorded. Samples of non-stimulated saliva were collected from the participants for five minutes. The salivary flow volume was calculated and expressed as ml/min. After the measurement of salivary flow, an aliquot of 1 ml was transferred to a test tube with 3 ml of hydrochloric acid (HCl 5 mM) for titration and the determination of salivary buffering capacity (SBC).
Treatment:
Diagnostic Test: Saliva Buffering Capacity
Diagnostic Test: Saliva flow rate
Diagnostic Test: Caries detection - dmtf index
Mild malnutrition
Description:
Dental caries experience was recorded using the dmft index. Active visible white spots were also recorded. Samples of non-stimulated saliva were collected from the participants for five minutes. The salivary flow volume was calculated and expressed as ml/min. After the measurement of salivary flow, an aliquot of 1 ml was transferred to a test tube with 3 ml of hydrochloric acid (HCl 5 mM) for titration and the determination of salivary buffering capacity (SBC).
Treatment:
Diagnostic Test: Saliva Buffering Capacity
Diagnostic Test: Saliva flow rate
Diagnostic Test: Caries detection - dmtf index
Moderate malnutrition
