Insights
This study measured thumb-sucking pressure in three children, finding significant individual variations in force and waveform. These pressure characteristics correlate with malocclusion, suggesting a link between thumb-sucking habits and dental development.
Area of Science:
- Dentistry
- Biomedical Engineering
- Pediatrics
Background:
- Thumb-sucking is a common habit in children that can influence dental and occlusal development.
- Understanding the forces exerted during thumb-sucking is crucial for assessing its potential impact on malocclusion.
Observation:
- A novel method using a pressure sensor on the thumb was employed to measure forces applied to the palate and mandible during thumb-sucking.
- Measurements were conducted on three female children during habitual thumb-sucking activities.
Findings:
- Peak pressures during thumb-sucking ranged from 2-4.5 kgw, demonstrating considerable individual variability.
- Waveform patterns of the pressure signals also showed significant differences between individuals.
- A correlation was observed between the characteristics of thumb-sucking habits, measured pressure, and the presence of malocclusion.
Implications:
- The measurement of thumb-sucking pressure provides a quantitative assessment tool.
- This technique can help elucidate the qualitative relationship between thumb-sucking behavior and the development of malocclusion.
- Findings may inform early intervention strategies for children with persistent thumb-sucking habits.
Abstract:
Measurement of the pressure applied to the anterior region of the palate and incisor region of the mandible during thumb-sucking was carried out 3 female children. A polyethylene bag embedded with a high-sensitivity small pressure sensor was fixed on the ventral side of the thumb so that the baroreceptor could be interposed between the thumb and palate during thumb-sucking. The children were allowed to perform habitual thumb-sucking, and the resulting pressure signals were detected with a high-response dynamic strainmeter and recorded. Measured peak pressures were about 2-4.5 kgw, with large individual variation, and waveform patterns also varied. Characteristics of thumb-sucking habits and thumb-sucking pressure were related to malocclusion. Measurement of thumb-sucking pressure is believed to be effective for assessment of the qualitative relationship between thumb-sucking and malocclusion.
