Gingivitis in children with malnutrition

Insights
Malnutrition did not significantly impact plaque and gingivitis levels in children aged 4-7 years. All children exhibited 100% prevalence, with no major differences between well-nourished and malnourished groups.
Area of Science:
- Pediatric Dentistry
- Nutritional Science
- Oral Health Epidemiology
Background:
- Childhood malnutrition is a global health concern, potentially affecting oral health.
- Gingivitis and plaque are common indicators of oral hygiene and overall health in children.
Purpose of the Study:
- To compare the prevalence and severity of gingivitis and plaque in well-nourished versus malnourished children.
- To assess oral health status in children aged 4 to 7 years based on nutritional status.
Main Methods:
- Assessed 291 children (4-7 years) categorized as well-nourished or malnourished using National Center for Health Statistics criteria.
- Evaluated plaque and gingivitis severity using the Plaque Index (PlI) and Modified Gingival Index (MGI) on primary teeth.
Main Results:
- 100% prevalence of both plaque and gingivitis was observed in all children studied.
- No statistically significant differences in PlI or MGI were found between well-nourished and malnourished groups.
- Gender did not show a significant impact on plaque or gingivitis levels.
Conclusions:
- Nutritional status, as defined by height-for-age, did not significantly influence the high prevalence of plaque and gingivitis in this cohort.
- A slight trend suggested potentially lower plaque and gingivitis in better-nourished children, warranting further investigation.
Abstract:
The purpose of the current study was to compare the prevalence and severity of gingivitis and plaque among 291 well- and malnourished children between the ages of 4 to 7 years. Using the National Center for Health Statistics criteria, the children were identified as normal (well nourished), having a height-of-age > 95% of standard. Selected primary teeth of each child were assessed using the Plaque Index (PlI) and the Modified Gingival Index (MGI). The results demonstrated a 100% prevalence of plaque and gingivitis. Also, there was no significant difference in the PlI and MGI in the well-nourished and malnourished groups, nor between males and females. However, there was a trend in the well-nourished group to less plaque and gingivitis when broken down into different stature-by-age percentiles.

Teeth
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...

A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...
