Prevalence of dilaceration in Jordanian adults

Abstract

Dilaceration is not common, but it is an important dental anomaly that affects all teeth. Recognizing the condition will facilitate endodontic, orthodontic and surgical treatment.

Curved canal-mishap and management- a review

“…[16] A progressive taper allows a greater degree of instrument and irrigant contact with the surfaces of the canal walls, thereby enhancing the effectiveness of cleaning. [13] However, the preparation of curved canals presents one of the greatest challenges in endodontics and is fraught with difficulties. Only the curvatures in mesio-distal plane can be seen on radiograph, though curvatures in the bucco-lingual plane are also evident in many teeth.…”

“…Failure of root canal treatment in curved canals is mainly due to procedural errors like ledges, fractured instruments, canal blockage, zip and elbow creation. [13]. The case presented above were treated with hand instrumentation with K files.…”

“…The final result of instrumentation of curved canals may be influenced by several factors such as flexibility and diameter of the endodontic instruments, instrumentation techniques, location of the foraminal opening and the hardness of dentin. [13] Ledge formation, blockages, perforations and apical transportation are accidents that have been observed to occur after preparation of curved canals. Management of such curved canals is an endodontic challenge; so, for a successful therapy, a thorough knowledge of root and root canal morphology is required.…”

Lower third molar fused with a supernumerary tooth: diagnosis and treatment planning using Cone-Beam Computed Tomography

“…The dental fusion etiology remains unknown and may be originated from either genetic or environmental factors [1][2][3]8,10,[12][13][14][15] . However some authors suggest that it may occur due to strength or pressure over the germs of adjacent teeth during their development which produces a tissue necrosis as a consequence.…”

“…Supernumerary teeth are additional teeth in the normal series which may occur in any region of the dental arch althoug they are more frequent in the maxilla than in the mandible [1][2][3][4][5][6] . They are considered uncommon and occur with a frequency of 0.3 to 3.8% in the population 7 and they are classified according to their position and form.…”
