Abstract
The Unusual Peg Shaped Mandibular Central Incisor – Report of Two Cases
Highlights
The human dentition is influenced by an array of multifarious, multilevel and multidimensional interactions between genetic, epigenetic and environmental factors. Brook (2009) stated that any mismatch between the molecular and cellular components during dental development manifests as distinct dental anomalies
These deviations can manifest as microdontia, macrodontia, hypodontia, oligodontia to name a few
The peculiarities may vary from microdontia, macrodontia, accessory cusps to hypodontia and hyperdontia
Summary
The human dentition is influenced by an array of multifarious, multilevel and multidimensional interactions between genetic, epigenetic and environmental factors. Brook (2009) stated that any mismatch between the molecular and cellular components during dental development manifests as distinct dental anomalies. Brook (2009) stated that any mismatch between the molecular and cellular components during dental development manifests as distinct dental anomalies These abnormalities may become apparent as structural and morphological variations or as alterations in the number of teeth. An apparently healthy 20 year old male reported for treatment of misaligned teeth His dental, medical, family and personal history was non contributory. Noted in the mandibular segment was the peg shaped right central incisor, clinically missing left lateral incisor and over retained left deciduous canine (Fig 1). On the panoramic radiography except for missing mandibular left lateral incisor, full compliment of permanent dentition including developing third molars was noted (Fig 2). Origin in the decayed deciduous maxillary right first molar Conspicuous was the peg shaped permanent mandibular left central incisor (Fig 3).
