It is important for a dental practitioner to have a clear understanding of the root canal morphology and its variations to perform successful root canal treatment. The inability to identify and adequately treat all canals of root canal system may contribute to the failure of root canal treatment. Objectives: Clinically determine the frequency or numbers of root canals per tooth in the maxillary second molar teeth in the local population.
Objectives: The purpose of the study was to examine efficacy of this procedure in necrotic immature permanent teeth. Methods: Forty patients were enrolled for pulp revascularization procedure by disinfecting the root canal with triple antibiotics paste for one to two weeks, followed by creating the blood clot, sealing the canal orifice with mineral trioxide aggregate as sealing material. Patients were recalled periodically for up to twenty four months. Results: Clinical evaluations demonstrated no adverse effects, during follow up 35 patients were asymptomatic, five cases of periapical periodontitis showed disappearance of sinus tract, on radiographic assessment there was progressive resolution of periapical radiolucency within first three-six months, the electric pulp test on sixth week demonstrated positive response, on radiographic evaluation there was progressive root length and thickness and continued root growth on six –twelfth months. Conclusion: Revascularization is a safe and efficacious method of dental pulp regeneration in this study. Keywords: Necrosis, Immature Permanent Teeth, Revascularization.
Introduction: It is important for a dental practitioner to have a clear understandingof the root canal morphology and its variations to perform successful root canal treatment.The inability to identify and adequately treat all canals of root canal system may contribute tothe failure of root canal treatment. Objectives: Clinically determine the frequency or numbersof root canals per tooth in the maxillary second molar teeth in the local population. Setting:Department of Operative Dentistry in Punjab Dental Hospital / de`Montmorency College ofDentistry, Lahore. Study Design: Randomized Control Trial. Study Period: 25th May 2013 to24th November 2013 (6 months). Results: This was a Cross sectional survey of 80 patients withsymptomatic irreversible pulpitis in maxillary second molar teeth in patients undergoing rootcanal treatment. The results showed that five (6.25%) patients had single root canal, seventeen(21.25%) patients had 2 root canals, forty (50%) patients had 3 root canals, seventeen (21.25%)patients had 4 root canals and one (1.25 %) patient had 5 root canals per tooth. In patientwith five canals, single root canal was present in distobuccal and palatal root each while threeroot canals were present in mesiobuccal root as MB-1, MB-2 and MB-3 canal. Conclusion:Local population have a lot of variations in root canal anatomy in second molar. So preclinicalknowledge can increase the success rate of root canal treatment.
Hemisection is a procedure involving the removal of an untreatable root with an accompanied crown portion while saving the other healthy root with adequate bone support. This case report represents the treatment of 2nd mandibular molar with irretrievable and unable to bypass separated instruments in the mesiobuccal canal of the mesial root. After sectioning the tooth, mesial root with the crown portion was extracted, and the remaining part of the tooth was restored as a premolar. Restorative rehabilitation was done by cementing a three-unit metal ceramic bridge. The good outcomes of endodontic treatment and patient demand towards the conservation of tooth encouraged the procedure of hemisection. For the preservation of terminal mandibular molars with irretrievable and unable to bypass separated instruments, hemisection can be considered as an alternative treatment option our objective is to conserve terminal mandibular molar with adequate bone support as a replacement in this area is complex, time consuming, and costly.
Clinical picture of patients taking methamphetamine for long duration includes rampant caries of the smooth surfaces of the whole dentition. The increasing use of methamphetamine in homosexuals is leading to the spread of HIV (human immunodeficiency virus). Easy availability and rapidly spreading nature of this drug (methamphetamine) results in worldwide increase of patients with medical and dental problems. Its effect on human dentition is highly damaging as patients with a beautiful smile begin to present a horrible picture of black, broken, and painful teeth within one year of methamphetamine use. Restoration of aesthetics and function of these teeth is not an easy task, and usually the first step to deal with this condition is counselling the patient to stop using this drug. Knowledge of methamphetamine-induced undesirable effects on the human body is important for the general dental practitioner as referral to mental health services is necessary in this condition.
