Insights
Oral diseases negatively impact children's quality of life. The Early Childhood Oral Health Impact Scale (ECOHIS) is a three-dimensional tool to measure this impact.
Area of Science:
- Pediatric Dentistry
- Oral Health Outcomes
- Quality of Life Research
Background:
- Oral diseases significantly affect children's well-being.
- Assessing the impact of oral health on quality of life is crucial for pediatric dental care.
Purpose of the Study:
- To evaluate how oral diseases influence children's oral health-related quality of life.
- To determine the dimensional structure of the Early Childhood Oral Health Impact Scale (ECOHIS) in a Chinese population.
Main Methods:
- The Chinese version of the ECOHIS was administered to 280 children aged 2-5 years.
- Confirmatory Factor Analysis (CFA) was employed to validate the three-dimensional construct of the ECOHIS.
Main Results:
- A 95.7% response rate was achieved with 268 valid questionnaires.
- Parent-reported frequent impacts included dental pain for children and feeling upset/guilty within the family.
- Confirmatory Factor Analysis supported a three-dimensional structure, with a modified model showing improved data fit.
Conclusions:
- Oral diseases demonstrably have a negative effect on children's oral health-related quality of life.
- The ECOHIS is confirmed as a valid three-dimensional instrument for assessing oral health impacts in young children.
Objective:
To investigate influence of oral diseases on child oral health-related quality of life, and to identify the dimensional structure of the early childhood oral health impact scale (ECOHIS).
Methods:
The Chinese language version of ECOHIS was applied to 280 patients aged 2-5 years old from the paediatric dentistry clinic of West China School of Stomatology, Sichuan University. The three-dimensional construct was confirmed by confirmatory factor analysis(CFA).
Results:
Two hundred and sixty-eight valid questionnaires (95.7%) were reclaimed. For the child impact section of the ECOHIS, "pain in the teeth, mouth or jaws" was the most frequently reported item by the parents. Item of "feeling upset or guilty" was most frequently reported in the family impact section of the ECOHIS. The CFA results indicated that all factor loadings to its items were 0.25-0.81 with one factor loadings less than 0.30. The modified factor model revealed a better fit to the data.
Conclusion:
Oral diseases have negative impact on the children's oral health-related quality of life. ECOHIS is a three-dimensional structure.

Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
Development of the Oral Microbiota
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...

Oral Cavity
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...
Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
