"localised/focal: affecting a single tooth or group (most common), often with altered shape. This form of microdontia most commonly affects maxillary lateral incisors (resulting in cone- or peg-shaped crowns, often known as "peg laterals") and maxillary third molars, followed by supernumerary teeth 3. Mandibular molars may have four cusps rather than five, and maxillary molars may have four cusps rather than three 5."

"Mutations in five genes (AXIN2, MSX1, PAX9, EDA, WNT10A) have been confirmed to be associated with isolated hypodontia 7."
