, on the other hand, is the term used to designate teeth that are larger than normal.
In the present study, the prevalence of other anomalies (odontoma, fusion, dens invaginatus, talon cusp, taurodontism, macrodontia
, dilaceration, ectopic eruption and microdontia) were observed more rare than other prevalence studies (4,7,10,17).
2 Disturbance in Size of teeth (Macrodontia
Intraoral examination revealed localized macrodontia
of lower left second permanent molar [Figure 1 & 2].
Talon cusps may be associated with other dental anomalies, especially in the permanent dentition, such as peg-shaped lateral incisors, impacted mesiodens and canines, odontoma, macrodontia
, dens invaginatus, supernumerary teeth, shovel-shaped incisors, bifid cingulum, additional tubercle on incisors, exaggerated Carabelli cusps, and microdontia of antimere teeth [Al-Omari et al., 1999; Gungor et al., 2000; Segura-Egea et al., 2003].
(1) the distance from cuspid to cuspid in maxilla in millimeter measured with digital vernier caliper with a least count upto 0.1mm (2) shape of arch (U-shape/ square/v shape) (3) teeth alignments in anterior region in both jaws (labioversion/linguoversion/rotation) (4) teeth's width and thickness from canine to canine in both arches (5) spacing and their location (6) number of missing teeth and their location (7) wear patterns (attrition erosion and abrasion) (8) the curve of biting edges ( sharp/smooth) (9) occlusal level (infraocclusion/ supraocclusion) (10) Unique dentistry ( macrodontia
The panoramic radiograph of the patient showed generalized macrodontia
abnormal shaped teeth with almost no roots in both primary and permanent dentition.
These include: supernumerary teeth, hypodontia, peg-shaped permanent maxillary lateral incisors, dens in dente, nail disorders, syndactyly40, successional coni- cal, macrodontia
and double permanent teeth.41 Brook et al41 reported that half of the primary double teeth have been followed by an anomaly in the permanent dentition and family histories of hypodontia or super- numerary teeth were found in some cases.
These include: Supernumerary teeth, hypodontia, peg-shaped permanent maxillary lateral incisors, dens in dente, nail disorders, syndactyly38, successional conical teeth, macrodontia
and double permanent teeth have been recorded following double primary teeth.39 Kolenc-Fuse40 reported that genetic linkage and molecular biology studies allowed the identification of the mutations responsible for some patterns of syndromic and non-syndromic tooth agen- cies.
