“…There have only been a few clinical case reports in which CBCT imaging was performed to aid in the diagnosis and treatment of mandibular paramolars 2,6,11) . In each case, it was reported that a paramolar and a molar were fused, and that their dental pulp was connected.…”

“…It is now possible to clearly identify points requiring attention in non-surgical endodontic treatment of teeth with a general morphology and to anatomically detect the cause of treatment failure because CBCT can be used to obtain a precise understanding of the 3-D structure of the teeth and dental pulp. There have been many reports on the usefulness of CBCT in the diagnosis and treatment-based management of teeth with a complicated morphology 2,6,8,11,12,14) . In the present case, too, it was possible to clearly distinguish morphological differences between the fusion of a molar and a paramolar and concrescence of a molar and a supernumerary tooth.…”

“…Some earlier studies have reported a pulpectomy in fused teeth comprising a paramolar and a molar in which CBCT was used 2,11) . In the present case, the dental pulp in the tooth root of the paramolar area was removed up to the position corresponding to the fusion boundary of the molar, and calcium hydroxide was applied to the wound surface of the dental pulp.…”

Supernumerary teeth in the molar area are classified as paramolars or distomolars based on location. They occur frequently in the maxilla, but only rarely in the mandible. These teeth are frequently fused with adjacent teeth. When this occurs, the pulp cavities may also be connected. This makes diagnosis and planning of endodontic treatment extremely difficult. Here we report a case of a mandibular second molar fused with a paramolar, necessitating dental pulp treatment. Intraoral and panoramic radiographs were obtained for an evaluation and diagnosis. Although the images revealed a supernumerary tooth-like structure between the posterior area of the mandibular second molar and mandibular third molar, it was difficult to confirm the morphology of the tooth root apical area. Subsequent cone-beam computed tomography (CBCT) revealed that the supernumerary tooth-like structure was concrescent with the root apical area of the mandibular second molar. Based on these findings, the diagnosis was a fused mandibular second molar and paramolar with a concrescent supernumerary tooth. A 3-dimensional (3-D) printer was used to produce models based on the CBCT data to aid in treatment planning and explanation of the proposed procedures to the patient. These models allowed the complicated morphology involved to be clearly viewed, which facilitated a more precise diagnosis and better treatment planning than would otherwise have been possible. These technologies were useful in obtaining informed consent from the patient, promoting 3-D morphological understanding, and facilitating simulation of endodontic treatment.

Supernumerary molars are relatively rare entities in maxillofacial region which can be classified broadly into distomolars and paramolars. Usually these occur singly and unilaterally. Occurrence of both paramolar and distomolar together is a very rare finding. This paper reports an unusual occurrence of combination of developing unerupted paramolar and distomolar follicles in the maxilla which was an incidental finding in the Orthopantamograph of a 13 year old girl. Patient was asymptomatic, hence was kept under observation and follow up. This paper describes the incidence and prevalence, possible etiological factors, complications, treatment options for supernumerary molars along with review of literature.

“…Conventional radiographs are routinely used to assess root canal anatomy, but because of their inherent limitations, conventional radiographs cannot definitively locate the root canal, and hence, cannot be used in the management of complicated cases. As a powerful diagnostic tool, spiral computed topography (SCT) has overcome the disadvantages of conventional radiography, and has attracted a great amount of attention in endo-dontic therapy [14][15][16].…”

We present a case of a patient with rare anatomy of a maxillary second molar with three mesiobuccal root canals and a maxillary third molar with four separate roots, identified using multi-slice computed topography (CT) and three-dimensional reconstruction techniques. The described case enriched/might enrich our knowledge about possible anatomical aberrations of maxillary molars. In addition, we demonstrate the role of multi-slice CT as an objective tool for confirmatory diagnosis and successful endodontic management.
