Clinical study on deciduous fused teeth and inherited permanent teeth

Area of Science:

• Pediatric Dentistry
• Dental Radiology
• Developmental Biology

Background:

• Deciduous fused teeth are a rare dental anomaly with potential implications for permanent dentition.
• Understanding the prevalence and characteristics of these fusions is crucial for early diagnosis and management.

Purpose of the Study:

• To determine the clinical characteristics of deciduous fused teeth.
• To evaluate the impact of deciduous fused teeth on the development of inherited permanent teeth.

Main Methods:

• Analysis of 14,404 panoramic radiographs from children aged 3-6 years.
• Recording the incidence and location of deciduous fused teeth.
• Assessing abnormalities in permanent teeth associated with deciduous fusions.

Main Results:

• The incidence of deciduous fused teeth was 3.06%, predominantly in the mandibular anterior region.
• Fusions were more common as single pairs, on the right side, and in the mandible.
• Deciduous fused teeth were associated with absent, present, or fused permanent teeth in 49.49%, 46.67%, and 3.84% of cases, respectively.

Conclusions:

• Deciduous fused teeth occur in 3.06% of young children, with specific patterns of location and laterality.
• These fusions have a notable impact on the development of permanent teeth.
• Pediatric dentists must actively monitor for permanent dentition abnormalities in children with deciduous fused teeth.
