Precise diagnosis and treatment plan should be made to achieve favourable results. In the present case report a 35-year-old male patient with continuous pain for almost one month after root canal treatment reported to the clinic. Diagnosis was made with the aid of CBCT Cone Beam Computer Tomography which confirmed apical fenestration. A comprehensive treatment plan was devised. Routine endodontic therapy with surgical intervention was done which yielded in the success of the treatment. Patient was followed up for six months and the healing process was noted to be uneventful.

Iatrogenic root perforation is a major complication of endodontic and restorative treatments, leading to impairment of tooth prognosis. Successful management of root perforations is dependent on early diagnosis of the defect, location of the perforation, choice of treatment, materials used, host response, and the experience of the practitioner. This case report presents the successful management of an iatrogenic lateral root perforation in a tooth with radiographic evidence of periodontal healing over one year follow-up.

Pregnant and lactating mothers were excluded from the study. Patients were divided into three groups using a block randomization method. The first group received scaling and root planning alone (SRP). The second group (SRP+GT) received scaling and root planning at baseline along with green tea for a period of 4 months. The third group received only green tea (GT) for a period of 4 months without any professional SRP. All the three groups showed significant (P < 0.05) improvement in all the parameters measured at baseline and compared at 2 and 4 months. The comparison of Plaque Index 2 and 4 months was highly significant (P < 0.05) for all the three groups. Comparison of gingiva...

Dentists and patients are facing a perplexity between saving a compromised tooth through endodontic treatment, retreatment or extraction. Though success rates of endodontic initial treatment have been improving over the years, persistence of periapical disease is far from being a rare condition. The most common therapeutical options for the re-treatment of teeth with periapical pathosis are non-surgical orthograde treatment and surgical treatment. Selection between alternative treatments should be based on assessment of respective benefits mainly healing. This paper reports two cases treated surgically due to failure of ortho-grade treatment and healed completely when followed-up over a period of 1 year. The method of evaluation of the healing was through radiographic method and clinical method.

Thus the combination of NaOCl and EDTA has been proven to have the perfect ability in removal of both organic and inorganic debris. These irrigants when used with conventional syringe irrigation were unable to penetrate the apical portion of the root canal, so new activation devices have come in the market which claims to be effective in delivering the irrigant to the working length. Objective/Aim: This study evaluated and compared the efficacy of recently introduced irrigation activation devices EndoActivator, Passive ultrasonic irrigation and Laser on removal of smear layer from the apical third of instrumented root canal using Scanning electron microscope. Methods: Forty three single rooted teeth were prepared with the help of protaper files and divided into four groups. Group I: EDTA o...

Methods: 30 human mandibular molars with fully formed apices were used for this study. Preoperative CBCT scans were made for each sample and PCD thickness was measured. The teeth were divided into 3 groups of 10 teeth each. Group 1: One Shape Group 2: Protaper Next Group 3: Revo S Root Canal Preparation was done for all the specimens in each group. Post instrumentation CBCT scans were made for each sample and PCD was measured. Results: There was significant loss of PCD following root canal instrumentation with fifth generation rotary files. Highest remaining pericervical dentin thickness was found in Group III (Revo S), followed by Group I(One Shape) and Group II(Protaper Next). Conclusion: Within the limitations of this study, it was concluded that there was significant loss of per...

Clinical studies, demonstrating preservation of pulpal vitality with the use of biomimetic materials in deep carious lesions, are lacking in the literature. Objective: This clinical study aims to assess the treatment outcome of vital pulp therapy using Biodentine in cases of deep carious lesion in a single visit treatment protocol. Methodology: Twelve posterior teeth with deep carious lesion with no signs of irreversible pulpitis were selected for the study. After rubber dam application, excavation of caries was performed until all infected dentin was removed leaving behind affected dentine. Biodentine was applied followed by immediate restoration with bonded composite resin. The patient was recalled at time intervals of 1 day, 1 month, 3 months, 6 months and up to 1 year for clinical and radiographic evaluation. Outcome was described in terms of success and failure. Success was defined as clinical absence of signs and symptoms, response to sensibility test on every recall visits, no tooth discoloration seen, and radiographical absence of periapical pathosis. Results: All the 12 patients were recalled at the end of 1 year for follow-up. The overall success rate was 83.4%. Two of the twelve cases required root canal treatment to relieve painful pulpitis. On clinical and radiographic examination, no signs of periapical pathosis were noted in the 10 successful cases. Conclusion: In deep carious lesions, vital pulp therapy with Biodentine has proven to maintain the pulpal vitality in permanent teeth with single visit treatment protocol.

As a result, combined injuries occur in dental tissues such as the pulp, dentin, cementum, periodontal ligament, and alveolar bone. Internal root canal inflammatory resorption involves a progressive loss of intraradicular dentin without adjunctive deposition of hard tissues adjacent to the resorptive sites. It is frequently associated with chronic pulpal inflammation, and bacteria might be identified from the granulation tissues when the lesion is progressive to the extent that it is identifiable with routine radiographs. With the advancement in technology, it is imperative to use modern diagnostic tools such as cone beam computed tomography and radiovisuography to diagnose and confirm the presence and extent of resorptions and fractures and their exact location. This case report presents a rare case having internal root resorption and horizontal root fracture with external inflammatory root resorption both which were treated successfully following guidelines by International Association of Dental Traumatology by nonsurgical treatment with 1 year follow-up.

Materials and Methods: Forty-eight extracted human mandibular first premolars were prepared and obturated with GP and AH Plus sealer. Samples were then randomly divided into four groups. Group I was retreated with MtwoR rotary system without solvent, Group II was retreated with MtwoR rotary system with Endosolv R as the solvent, Group III with D-RaCe rotary system without solvent, and Group IV with D-RaCe rotary system and Endosolv R solvent. The cleanliness of canal walls was determined by stereomicroscope (×20) and AutoCAD software. Kruskal-Wallis test and Mann-Whitney U-test were used to compare the data. Results: Results showed that none of the retreatment systems used in this study was able to completely remove the root canal filling material. D-RaCe with or without solvent showed significantly (P > 0.05) less filling material at all levels compared to MtwoR with/without solvent. Conclusion: Within the limitation of the current study, D-RaCe rotary retreatment system is more effective in removing filling material from root canal walls when compared to MtwoR rotary retreatment system.

So thorough knowledge of both the external and internal anatomy of teeth is an important aspect of root canal treatment. With the advancement in technology it is imperative to use modern diagnostic tools such as magnification devices, CBCT, microscopes, and RVG to confirm the presence of these aberrant configurations. However, in everyday endodontic practice, clinicians have to treat teeth with atypical configurations for root canal treatment to be successful. This case report presents the management of a mandibular first molar with six root canals, four in mesial and two in distal root, and also emphasizes the use and importance of Cone Beam Computed Tomography (CBCT) as a diagnostic tool in endodontics.
