The pattern of congenitally missing teeth seen in monozygotic twins is different, suggesting an underlying epigenetic factor, which may be due to the simultaneous occurrence of two anomalies. [33] This multifactorial aetiology involves environmental factors which trigger the genetic anomalies, resulting in the occurrence of dental agenesis.
In 1987, a young girl named Jessica McClure fell down a narrow well pipe in her family's Texas property. Ron Short, a roofing contractor who was born without collarbones because of cleidocranial dysostosis and thus could collapse his shoulders to work in cramped corners, arrived at the site and offered to go down the shaft.

Dental management is a cornerstone of ED treatment due to the common occurrence of missing, malformed, or delayed eruption of teeth. Dental prostheses, such as dentures, partial dentures, or implants, are frequently used to restore function and aesthetics in patients with hypodontia, oligodontia, or anodontia. [ 3 ]
The primary (baby) teeth generally start coming in by 6 months of age, and all 20 teeth may be in by two and a half years of age. The eruption timing varies greatly. There may be an incomplete formation of the enamel on the teeth (enamel hypoplasia) that makes the teeth more vulnerable to caries (cavities). There may be missing teeth eruptions.
Tooth development can be delayed with increasing severity of CLP. Some of the dental problems affect the primary teeth, but most of the problems arise after the permanent teeth erupt. Problems may include fused teeth, missing teeth, and extra teeth erupting behind normal teeth. Missing teeth or extra teeth are both normal occurrences.
Tooth pathology is any condition of the teeth that can be congenital or acquired. Sometimes a congenital tooth disease is called a tooth abnormality.These are among the most common diseases in humans [1] The prevention, diagnosis, treatment and rehabilitation of these diseases are the base to the dentistry profession, in which are dentists and dental hygienists, and its sub-specialties, such ...
Individuals with this condition typically have the following symptoms: complete absence of both the deciduous and permanent teeth, cone-shaped canines and incisors, generalized dysplasia of the nails, palmoplantar hyperkeratosis, chronic skin dryness, and variable degrees of both hypotrichosis and either hyperhidrosis or hypohidrosis.
