For the analysis of clinical and radiographic sequelae in permanent teeth, the following clinical signs were considered: discoloration of the crown, hypoplastic enamel, crown dilaceration
; Radiographic signs: root dilaceration
, odontoma, root duplication, incomplete root development, permanent tooth malposition, eruption disturbances.
Complications were classified as; impaction of permanent teeth, dislocation, dilacerations
of teeth and root resorption.
The frequency of other anomalies was as follows: molar-incisor hypomineralization 0.25%, turner hypoplasia 0.1%, fluorosis 0.1%, odontoma 0.1%, fusion 0.09%, gemination 0.06%, amelogenesis imperfecta 0.05%, dens invaginatus 0.03%, talon cusp 0.02%, taurodontism 0.02%, macrodontia 0.02%, dentinogenesis imperfecta 0.02%, dilaceration
0.02%, ectopic eruption 0.01% and microdontia 0.01%.
The criteria for recognizing root dilaceration
vary in the literature.
Cone beam computed tomography, labial access cavity preparation, maxillary lateral incisor, root canal treatment, root dilaceration
Prevalence of root dilacerations
in Central Anatolian Turkish dental patients.
of a central incisor Patient 4 a 12 year old girl was referred after extraction of a midline supernumerary tooth followed by exposure and traction of the central incisor which failed to induce eruption (Figure 4a).
An evaluation of the incidence and amount of apical root resorption and dilaceration
occurring in orthodontically treated teeth, having incompletely formed roots at the beginning of Begg treatment.
describes a tooth whose root and crown display a bend or angulation.
Trauma Trauma during tooth development may cause severe enamel hypoplasia or dilaceration
of the teeth.
in permanent teeth is a rare malformation representing 3% of the total dento-alveolar injuries.
