The aim of the study was to review and determine whether guided endodontic treatment or conventional technique is a better treatment alternative for patients with calcific metamorphosis. The review was done according to the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) statement (PRISMA) guidelines. Databases were searched from 2000 to December 2022 for studies reporting the treatment of calcific metamorphosis through guided endodontic treatment or conventional technique. Quality assessment of the included was evaluated using the critical checklist put forward by the Joanna Briggs Institute for case reports, while for the included in vitro studies, the critical checklist put forward by the Critical Appraisal Skills Program was used. Results were plotted through pooled forest plots and publication bias was explored through funnel plots using RevMan (Review manager) 5.3 version. Summary statistic measure in the form of standardized mean difference (SDM) was used. Five studies were included in qualitative synthesis and three studies for quantitative synthesis. The pooled estimate (SMD) of −0.97 (−1.83–0.10) favors guided endodontic treatment employing a random effect model with an I 2 (heterogeneity) value of 83% and a P = 0.03. Publication bias showed symmetric distribution with a systematic heterogeneity. These procedures and techniques are highly promising with better results. Treatments of a minimally invasive nature can be performed, with a reduction in chairside time. [ABSTRACT FROM AUTHOR]

Hemisection is conservative way of preserving tooth, which is defined as the surgical procedure that involves removal of a weakened root and compromised crown portion which may be affected by periodontal, endodontic, or structural failures. It aims to efficacious atternative modality in the extraced to save multirooted teeth. This treatment option should be considered when caries, resorption, perforation, or periodontal damage is confined to one root, whereas the other root is healthier. As long as, Expected results can be achieved with this treatment by following the proper diagnostic, endodontic, surgical, prosthetic, and maintenance procedures are followed, this treatment can produce. Present study describes the successful treatment two patients with severely damaged mandibular molars through hemisection. The procedure was successfully and the remaining portion of the tooth was restored with a prosthesis. The patients were followed-up for several months, and the outcome was satisfactory, with no recurrence of symptoms. Hemisection can be an effective treatment option for preserving a damaged tooth, and this case report demonstrates its successful application in a clinical setting. [ABSTRACT FROM AUTHOR]

Invasive cervical resorption is a relatively uncommon form of a chronic inflammatory process that results in loss of dentine and is usually initiated in the pulp space. It begins as a localised resorptive process that initiates in the area of the root beneath the epithelial attachment and the coronal part of the alveolar process. The lesion is mainly detected on radiographs and exhibits no external signs. The limitations of conventional radiography make Cone Beam Computed Tomography (CBCT) an effective and accurate method of diagnosing root resorptions. The tooth is normally asymptomatic, and the diagnosis is usually made based on a routine examination. Most authors refer to dental trauma, whitening agents, and orthodontic treatment as aetiologic factors. This disorder necessitates a thorough study of the pathologic process in order to determine the source and stop the resorptive phenomenon. The treatment should seek to completely remove the resorptive defect and rebuild it with an appropriate filling substance. Biodentine, a calcium silicate-based material, can be used to fill resorptive defects in the teeth. Furthermore, biodentine has some desirable additional properties over Mineral Trioxide Aggregate (MTA), such as improved antibacterial properties, bioactivity-inducing hard tissue formation, good handling, self-adhesion to dentine, and shorter setting time. Hence, this article presents a case report of external cervical resorption of the maxillary central incisor. Biodentine along with collagen membrane was used to fill the resorptive defect. One year radiographic follow-up showed stability of the resorption site. [ABSTRACT FROM AUTHOR]

Introduction: The purpose of this study was to compare the incidence of dentinal crack formation after root canal preparation using ProTaper Next, OneShape and Hyflex electrodischarge machining (HEDM). Materials and Methods: A total of 75 extracted mandibular premolars were selected. The root canals were instrumented using ProTaper Next, OneShape and HEDM rotary files. All roots were horizontally sectioned at 3, 6 and 9 mm from apex with slow-speed saw under water cooling. The sections were observed under a stereomicroscope at x25 to determine the absence or presence of crack. Data were analyzed using post hoc test and one-way ANOVA. Results: ProTaper Next and HEDM produced significantly less cracks than OneShape. Conclusion: Within the limitation of this in vitro study, it can be concluded that nickel-titanium instruments may cause cracks on the root surface. ProTaper Next and HEDM tend to produce less number of cracks as compared to OneShape. [ABSTRACT FROM AUTHOR]

Introduction: Sodium hypochlorite, is the irrigant of choice for many clinicians, but its strong toxic and damaging effects on vital periapical tissues is always a matter of concern. So, the search for a root canal irrigant with a broad antimicrobial spectrum yet with a limited toxicity on vital tissues is always desirable. Aim: The study evaluated antimicrobial efficacy of Electro- Chemically Activated (ECA) water as a root canal irrigant against E. faecalis. Materials and Methods: Forty eight single rooted human teeth were decoronated to a length of 15mm. All teeth were divided into four test groups (group A - ECA anolyte, group B - 1% sodium hypochlorite, group C - 3% sodium hypochlorite, group D - distilled water) of 12 each. Only 1ml of Ringer's solution and calibrated suspensio of E. faecalis was injected into each canal, aspirated and placed on agar plates and incubated aerobically at 37°C for two days. The suspension was aspirated and spread onto the blood agar plate and incubated. All samples were irrigated with four test solutions and Brain Heart Infusion (BHI) solution was injected into each canal then aspirated and spread onto blood agar and incubated. After inoculations Colony Forming Unit (CFU) and optical density was measured under a microscope and spectrophotometer. The data obtained were statistically analysed by one way ANOVA and Dunkan's multiple range test. Results: CFU reduction was not statistically significant between the test groups. The optical density showed statistically significant difference between the test groups (p≤0.001). Conclusion: The antimicrobial efficacy of ECA was found to be comparable to sodium hypochlorite solutions. [ABSTRACT FROM AUTHOR]

Background: Aim of the study was to evaluate sealing ability of five different root end filling materials by dye penetration method. Materials and Methods: About 100 extracted maxillary central incisors were sectioned at Cementoenamel junction. Access cavities were prepared, instrumented chemo-mechanically, and obturated with laterally condensed gutta-percha and AH Plus sealer. Access cavities were sealed with composite resin. After 3 mm of root resection a 3 mm deep root-end cavity was prepared in each tooth. The teeth were retrofilled with glass ionomer cement (GIC), super-ethoxy benzonic acid (EBA), gray-mineral trioxide aggregate (MTA), white-MTA and biodentine. Three coats of nail varnish were then applied to the whole surface of total length of each root except tip of the root where retrograde filling was applied. All roots were stored in 1% solution of methylene blue for 72 h; after which roots were rinsed under tap water. The teeth were sectioned buccolingually, depth of dye penetration was evaluated under stereomicroscope. Results: The overall results showed no statistically significant difference between two types of MTA and biodentine, but all the three materials are superior to GIC, super-EBA. Conclusion: Both forms of MTA, biodentine provide a better seal than GIC, super-EBA. [ABSTRACT FROM AUTHOR]
