Background Tooth abnormalities are most often present in individuals with oral clefts than general population, and lead to a long-term impact on facial anatomy and self-esteem. The purpose of this study was to compare the proportion of dental anomalies between the cleft side and non-cleft side in individuals with non-syndromic unilateral alveolar clefts (AC). Material and Methods Twenty cone ...

Tooth transposition is a disorder in which a permanent tooth develops and erupts in the normal position of another permanent tooth. Fusion and gemination are developmental disturbances presenting as the union of teeth. This article reports the nonsurgical retreatment of a very rare case of fused teeth with transposition. A patient was referred for endodontic treatment of her maxillary left firs...

Sir,?I would like to ask your readers for some reference to a case of a median incisor tooth if any of them are acquainted with one. Last year a prisoner in my jail was found to have what appeared to be one in the upper jaw. Situated between the two central incisors, which were very long and tush-like, and had their enamel worn away half way up, was a shorter rounded peg-like tooth which also h...

Chipped and broken functional teeth are common in modern sharks with serrated tooth shape. Tooth damage consists of splintering, cracking, and flaking near the cusp apex where the enameloid is broken and exposes the osteodentine and orthodentine. Such damage is generally viewed as the result of forces applied during feeding as the cusp apex impacts the skeletal anatomy of prey. Damage seen in s...

BACKGROUND The CBCT imaging technique exhibits proper accuracy to determine the internal anatomy of teeth. Therefore, this technique can use to estimate age by measuring the amount of decrease in the volume of the pulpal cavity of teeth. The aim of the present study was to evaluate the correlation between chronological age and pulp-to-tooth volume ratios in anterior teeth with the use of the CB...

The vast majority of mandibular second molars have two roots with three root canals; however, variations in molar root canal anatomy are not uncommon. To the best of our knowledge, four rooted mandibular second molar with three mesial roots and one distal root has never been reported. Herein, we present the endodontic management of a four rooted mandibular second molar tooth, diagnosed with the...

Magnetic resonance neurography is a technique that complements clinical and electrophysiological study of the peripheral nerves and brachial and lumbosacral plexuses. Numerous focal processes (inflammatory, traumatic, primary tumors, secondary tumors) and diffuse processes (diabetic polyneuropathy, chronic idiopathic demyelinating polyneuropathy due to amyloidosis or Charcot-Marie-Tooth disease...

Dens invaginatus is a developmental anomaly resulting from epithelial invagination of the tooth crown before calcification. Endodontic treatment of teeth affected by dens invaginatusmay be difficult and complex due to aberrant anatomy. Combined orthograde and surgical approaches for successful treatment of dens invaginatus are effective. This report describes the successful treatmentand results...

Mandibular premolars often show aberrant anatomy varying from one to three canals. The incidence of occurrence of 3 canals has been recorded to be 0.46 - 0.5 %. We report a case of mandibular second premolar with 3 canals, which was initially diagnosed radiographically by shift cone technique and confirmed by clinical examination. The tooth was successfully obturated and restored. It remained a...
