Dental Article 🔽 Do Wisdom Teeth Cause Dental Crowding? Updated Evidence and Clinical Insights ... Wisdom teeth, or third molars, typically erupt between the ages of 17 and 21, coinciding with the period when patients often notice anterior crowding of the mandibular incisors.

✅ Until What Age Can Interceptive Orthodontics Be Used?
Interceptive orthodontics is typically indicated:

▪️ Between 6 and 10 years of age
▪️ During early mixed dentition
▪️ While active skeletal growth is present
Its effectiveness decreases significantly after the pubertal growth spurt, when growth modification is limited.

💬 Discussion
There is ongoing debate regarding the timing of orthodontic intervention. While not all malocclusions require early treatment, specific conditions such as crossbites, severe crowding, and skeletal discrepancies benefit greatly from interceptive orthodontics. Evidence supports early intervention when growth modification is feasible and when delaying treatment may worsen prognosis.
Proper case selection is critical to avoid overtreatment.

📊 Comparative Table: Interceptive Orthodontics vs Maxillary Orthopedics

Aspect	Advantages	Limitations
Interceptive Orthodontics	Prevents worsening of dental malocclusions during growth	Limited effect once skeletal growth is completed
Maxillary Orthopedics	Modifies jaw growth and skeletal relationships	Highly dependent on patient age and compliance

✍️ Conclusion
Interceptive orthodontics is a preventive and growth-guided approach that plays a fundamental role in modern pediatric dentistry. By addressing developing malocclusions early, it reduces treatment complexity, improves outcomes, and supports healthy craniofacial development.

✅ Etiology: Why Does Asthma Affect Oral Health?
The oral consequences associated with asthma are multifactorial and include:

▪️ Chronic mouth breathing, leading to reduced salivary flow
▪️ Use of inhaled medications, especially corticosteroids and β2-agonists
▪️ Lower salivary pH and buffering capacity
▪️ Alteration of oral microbiota
▪️ Increased plaque accumulation
👉 Asthma-related xerostomia is a key factor in oral disease development.

✅ Main Oral and Dental Consequences of Asthma

1. Dental Caries
Children with asthma have a higher prevalence of dental caries, mainly due to:

▪️ Reduced salivary flow
▪️ Increased consumption of sugary beverages to relieve dry mouth
▪️ Acidic formulations of inhaled medications
Asthmatic children are at increased risk of early enamel demineralization.

2. Dental Erosion

▪️ Frequent exposure to acidic inhalers
▪️ Reduced salivary neutralization
▪️ Possible association with gastroesophageal reflux, common in asthmatic patients
Dental erosion may affect both primary and permanent dentition.

3. Gingivitis and Periodontal Inflammation

▪️ Increased plaque retention due to dry oral tissues
▪️ Altered immune response
▪️ Inflammatory effects of corticosteroids
Asthma has been linked to higher gingival inflammation indices in adolescents.

4. Oral Candidiasis

▪️ Common in children using inhaled corticosteroids without spacers
▪️ Favored by immunosuppressive effects and reduced saliva

5. Malocclusion and Craniofacial Changes
Chronic mouth breathing may contribute to:

▪️ Anterior open bite
▪️ Posterior crossbite
▪️ Narrow maxillary arch
