Understand treatment options for these patients 3. Refer appropriately for management Why do these occur? Common causes of dental anomalies: Alterations in tooth number: Alterations in tooth number: Hyperdontia/supernumerary Supplemental Mesiodens Tuberculate Conical Alterations in size: Macrodontia Microdontia Generalised or localised Alterations in shape: Concrescence Fusion Diagram showing the difference between concesence where only the roots are joined, fusion where two teeth are joint but their pulps are and gemination where the tooth tooth are joined including their pulps Gemination Alterations in shape: Dens in dente (Dens invaginatus) Dens evaginatus Talon cusps Alterations in shape: Taurodontism Hypercementosis Alterations in shape: Dilaceration Enamel Pearl Abnormalities of the dental pulp: Resorption Internal/External Physiologic Idiopathic Pathologic Abnormalities of the dental pulp: Pulp calcification Pulp stones Secondary/reparative dentine Pulp obliteration Abnormalities in tooth position: Submerged teeth Impacted teeth Transposed teeth Ankylosed teeth Abnormalities in tooth structure: Hypoplasia Molar incisal hypoplasia Hypomineralisation Turner tooth Abnormalities in tooth structure: Dentinogenesis Imperfecta Type I, II and III Amelogenesis Imperfecta Hypoplastic AI, hypocalcified AI, hypomaturation AI, hypomaturation-hypoplasia AI Abnormalities in tooth structure: Staining Tetracycline staining How are these conditions managed? How are these conditions managed? This would be on a case by case basis. Some management options may be.. Do nothing and review – many of these conditions don’t need treatment unless there is aesthetic concern Specialist referral – many of these conditions are complicated and if treatment is required may be best completed by a multidisciplinary team in secondary care Restoration – some conditions may be manageable in primary care with restorations e.g. composite resin or pre-formed metal crowns If in doubt, get a second opinion! Thank You! References Welbury, R; Duggal, MS & Hosey, MT.
