Insights
Salivary flow rate in healthy children aged 6-11 years is consistent, unaffected by age or gender. This data aids in treating drooling in children with special needs.
Area of Science:
- Pediatric Dentistry
- Oral Physiology
Background:
- Reference data on salivary flow rate is crucial for managing conditions like drooling.
- Understanding normal salivary function in children is essential for effective treatment planning.
Purpose of the Study:
- To establish reference values for unstimulated salivary flow rate in healthy 6-11-year-old children.
- To provide data for the management of drooling in handicapped children.
Main Methods:
- Unstimulated saliva was collected from 62 healthy children (aged 6-11) using the swab method under standard conditions.
- Salivary flow rate was measured by the weight increase of cotton rolls after 5 minutes.
- The influence of age, gender, and gland type on salivary flow rate was analyzed.
Main Results:
- No significant differences in salivary flow rate were observed between boys and girls, or across the 6-11 age range.
- The swab method demonstrated good reproducibility for salivary flow rate measurement.
- Parotid glands exhibited equal flow rates (0.15 ml/min), while submandibular and sublingual glands secreted 0.32 ml/min.
Conclusions:
- Age and gender do not influence salivary flow rate in healthy 6-11-year-old children, simplifying measurement protocols.
- The swab method is a reliable, easy-to-perform, and well-tolerated technique for assessing salivary flow rate in schoolchildren.
Objective:
To obtain reference data on the unstimulated salivary flow rate in healthy 6-11-year-old boys and girls, for use in the treatment of drooling in mentally and physically handicapped children.
Methods:
Under standard conditions unstimulated saliva was collected from 62 healthy children using the swab method. Flow rate was determined by calculating the increase in weight of cotton rolls placed in the mouth for 5 min. The influence of the variables age, gender and type of gland were evaluated.
Results:
No significant difference was found between the flow rate in boys and girls or between the children in this age window. The swab method showed good reproducibility. The right and left parotid glands had equal flow rates of 0.15 ml/min. The flow rate in the floor of the mouth secreted by the submandibular and sublingual glands was 0.32 ml/min.
Conclusions:
In healthy children of 6-11 years, age and gender did not influence the salivary flow rate and therefore do not have to be taken in consideration when measuring salivary flow rate. The swab method was reliable, easy to carry out and well-tolerated by the group of schoolchildren.
