Prevalence of dental caries and sugar consumption among 6–12-y-old schoolchildren in La Trinidad, Benguet, Philippines

Abstract

Objective:

To determine the prevalence of dental caries and the level of sugar consumption among 6–12-y-old schoolchildren in La Trinidad, Benguet, Philippines.

Design:

A Cross-sectional study as a baseline survey for a later intervention program. A questionnaire was distributed to obtain information on dental history and total consumption of food with sugar. Caries were diagnosed based on the WHO recommendation.

Results:

A total of 1200 schoolchildren, aged 6–12 y were included. The prevalence of dental caries in primary dentition was 71.7% and in the permanent dentition, 68.2%. The mean total decayed, extracted due to caries and filled primary teeth (DMFT) and decayed, missing and filled permanent teeth (DMFT) were 4.12 (s.d. 4.03) and 2.40 (s.d. 2.57), respectively. As age increased the mean DMFT increased. Majority (70%) had tooth brushing practices, and less than half (42.5%) had a dental visit only when necessary. Their sugar intake was twice more than the WHO recommendation with a mean daily total intake of 59 g per person. Most common sources of dietary sugar were hard candies (89%), banana cue (84.9%), camote cue (84.9%) and soft drinks (84.4%). No significant correlation was found between sugar intake and dental caries.

Conclusion:

The results indicate that dental caries is highly prevalent and increase with augmented sugar consumption. This maybe due to a widespread neglect of oral health and an increased availability of refined sugary products. Caries rates mirrored those of the developing countries with untreated lesions dominating all ages. The high level of untreated caries in all age groups is a cause for concern.
