Insights
Toe sucking, a rare habit, can negatively impact a child's dental health and overall well-being. Early intervention for this nonnutritive sucking habit can resolve dental issues and reduce recurrent fevers.
Area of Science:
- Pediatric Dentistry
- Child Health
- Habit Cessation
Background:
- Digit sucking is a common nonnutritive sucking habit in children.
- Toe sucking is an unusual habit with potentially deleterious effects.
- Recurrent pyrexia in children often requires thorough investigation.
Purpose of the Study:
- To report a case of a seven-year-old child with a toe sucking habit.
- To investigate the link between toe sucking and recurrent pyrexia.
- To highlight the dental and general health implications of toe sucking.
Main Methods:
- Case report of a seven-year-old child presenting with recurrent pyrexia.
- Dental evaluation for potential causes of fever.
- Detailed history taking, including nonnutritive sucking habits.
- Intervention for habit cessation and orthodontic management.
Main Results:
- Dental examination did not reveal the cause of recurrent pyrexia.
- Discovery of a persistent left great toe sucking habit since infancy.
- The habit caused dentofacial abnormalities (cross-bite) and affected the toe.
- Cessation of the habit and orthodontic intervention led to cross-bite correction and reduced pyrexial episodes.
Conclusions:
- Toe sucking is a detrimental habit with significant health consequences.
- This habit can contribute to dentofacial structures changes and recurrent fevers.
- Early intervention is crucial for managing toe sucking habit and its associated health issues.
Abstract:
Digit sucking is common nonnutritive sucking habit in childhood. However it is unusual to find toe sucking habit in children. We report a case of a seven-year-old child sucking great toe of the left foot. The child was referred by her paediatrician for dental evaluation due to her complaint of recurrent episodes of pyrexia. A dental evaluation was warranted as no particular system contributed to such recurrent episodes of fever in this child. Although dental examination did not reveal any cause for recurrent episodes of pyrexia, as a part of routine history taking we discovered that this child indulges frequently in sucking the great toe of her left foot since infancy. Any nonnutritive sucking habit is considered deleterious; this habit also caused significant effect on the child's dentofacial structures, sucked toe, and her general health. Hence the treatment plan was formulated for immediate cessation of habit. Appropriate interception of habit and timely orthodontic intervention led to not only early interception of cross-bite but also decrease in pyrexial episodes. This case report describes the pernicious effects of toe sucking habit and its relevance to recurrent pyrexia in children.

Drugs Acting on Autonomic Ganglia: Stimulants
Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating...
