Complications may occur during and after endodontic treatment, which may be due to negligence of the operator. The surgical treatment of a case presenting pain and persistent pus discharge and swelling due to the extrusion of the root canal filling to the base of the nasal floor between left maxillary lateral and canine teeth is presented in this report. First, carelessness was during root canal treatment that was over obturated and second time during extraction in which overextended gutta-percha remained in the bone, caused the complications like pain, persistent pus discharge, and headache. Clinicians should be aware of the fact that endodontic instruments and filling materials (solid or liquid) can be extended in such a degree that can lead to neurological or sinus complications.
Endodontic implants were introduced back in 1960. Endodontic implants enjoyed few successes and many failures. Various reasons for failures include improper case selection, improper use of materials and sealers and poor preparation for implants. Proper case selection had given remarkable long-term success. Two different cases are being presented here, which have been treated successfully with endodontic implants and mineral trioxide aggregate Fillapex (Andreaus, Brazil), an MTA based sealer. We suggest that carefully selected cases can give a higher success rate and this method should be considered as one of the treatment modalities.
Objective: To compare the detection rate of root canal orifices of maxillary first molar by various techniques in the Indian population. Material and Methods: A total of 50 maxillary 1st molar cases were selected and sequentially divided into four groups: Group I: Naked eye; Group II: Surgical loupe; Group III: Surgical operating microscope; and Group IV: Fluorescein sodium dye. After access opening, the number of root canal orifices was detected in all cases with these methods. Results: By naked eye and surgical loupe, a total of 171 root canal orifices were detected, by a surgical operating microscope, 176, and by fluorescein sodium dye, 177 root canal orifices were detected. The detection rate of root canal orifices is as follows: Group I (96.61%) = Group II (96.61%) < Group III (99.44%) < Group IV (100%) and detection rate of MB-2 canal orifices Group I (40%) = Group II (40%) < Group III (50%) < Group IV (52%). No significant difference in the number of canal orifices detected could be seen for any of the comparisons. No significant difference was observed between the naked eye and surgical loupe techniques. Although the surgical operating microscope detected more root canal orifices, it did not have a significantly higher detection than the other two techniques. Conclusion: No significant difference was seen among various methods. However, the use of a surgical operating microscope and fluorescein sodium dye increased the detection rate of root canal orifices.
The root canal anatomy of maxillary first molars has been described as three roots with three canals, and the commonest variation is the presence of a second mesiobuccal canal. However, some unusual number of canals should always be expected. Careful examination of the pulpal floor is recommended to locate all the canals and should be confirmed with conventional radiographic methods and additional imaging systems. The case reports describe the successful endodontic treatment of two maxillary first molars with six canals, with the help of dental computed tomography imaging system.
