Familial cases of missing mandibular incisor: three case presentations

Area of Science:

• Dentistry
• Genetics
• Developmental Biology

Background:

• Hypodontia is a common dental anomaly characterized by the congenital absence of teeth.
• Agenesis, the failure of tooth development, is the primary cause of hypodontia.
• Typically, third molars, maxillary lateral incisors, and second premolars are the most frequently affected teeth.

Observation:

• This report details three distinct cases of hypodontia.
• Each case specifically involves the congenital absence of a mandibular incisor.
• This presentation highlights a less common pattern of tooth agenesis.

Findings:

• The study confirms that hypodontia can manifest in various patterns.
• Mandibular incisor agenesis, though less common, is a documented form of hypodontia.
• The findings underscore the variability in dental development.

Implications:

• Understanding diverse patterns of hypodontia is crucial for accurate diagnosis.
• Early identification of missing teeth aids in timely orthodontic and restorative planning.
• Further research into the genetic and developmental factors of rare hypodontia patterns is warranted.
