Lower third molars in double tooth form associated with complex tooth morphology in a female patient – case report
Introduction: Schizodontia (germination) and fusion are tooth anomalies hard to distinguish, therefore referred to as ‘double tooth’. The condition may raise from division of a single tooth germ or from fusion with a supernumerary tooth. The field theory explains association of tooth position and it’s susceptibility to anomalies of form and number. Case description: A 25 year old female patient came to our observation with three third molars (18, 38, 48) which showed two to three additional cusps. Patient had difficulties with oral hygiene maintenance which caused pericoronitis. Lateral incisors and canines had marked tuberculum dentale. Upper first and second molars both expressed Carbelli’s cusp, grade 6 and 5 respectively according to ASUDAS. Lower first and second molars had 6 and 5 cusps, respectively. Orthopantomogram showed teeth 38 and 48 had accessory cusps under the buccal mucosa and 48 had enlarged distal root. Family anamnesis revealed father had supernumerary tooth in upper frontal region and cousin had supernumerary permanent lower lateral incisors. Discussion: Findings on 18, 38 and 48 indicate schizodontia while alternative could be fusion with supernumerary tooth. According to the field theory, third molars as last teeth in the molar field, are the most susceptible to aberrations. This may be related to genetic and epigenetic factors and duration of the development. Conclusion: Processes that occurred during tooth formation resulted in complex tooth morphology which may be a family trait in this case
