Summary
Boys with unilateral cleft lip and palate experience significant tooth eruption delays, especially in the affected maxillary quadrant. Second incisors show the most pronounced delays, linked to morphological changes and hypodontia.
Area of Science:
- Dentistry
- Oral and Maxillofacial Surgery
- Pediatric Dentistry
Background:
- Unilateral cleft lip and palate (UCLP) affects maxilla development and tooth eruption patterns.
- Understanding these disruptions is crucial for effective orthodontic and surgical management.
Purpose of the Study:
- To investigate and compare the eruption timing of deciduous and permanent teeth in the affected and unaffected maxillary quadrants of boys with UCLP.
Main Methods:
- Comparative analysis of tooth eruption timelines.
- Observation of deciduous and permanent dentition in UCLP patients.
Main Results:
- Significant eruption delays observed in the cleft quadrant, particularly for second incisors (up to 2 years).
- Delays also noted for permanent canines (1 year) and premolars (6-18 months).
- First incisors and molars erupted symmetrically, unaffected by the cleft.
Conclusions:
- Tooth eruption is significantly impacted by UCLP, with specific teeth showing marked delays.
- Morphological anomalies and hypodontia contribute to delayed or absent eruption of second incisors.
- Space deficiency in the hypoplastic maxilla may explain delays in other permanent teeth.
