Context: Retention of the rubber dam is done with metallic or nonmetallic clamps for isolation. The two types of metallic clamps most frequently used are winged and wingless. The clinical efficacy of both clamps is needed to be compared., Aim: The aim of the study was to evaluate and compare the postoperative pain and clinical efficacy of winged clamps and wingless metallic clamps in rubber dam isolation of permanent molars in class I restoration., Materials and Methods: After obtaining ethical approval and CTRI registration, a total of 60 patients with mild-to-moderate deep class I caries were included after obtaining informed consent and randomly allocated into two assigned groups: Group A - winged clamp and Group B - wingless clamp, with n = 30 per group. Local anesthesia was administered and the tooth was isolated using a rubber dam as per the standardized protocol. The postoperative evaluation was done for pain using the Verbal Rating Scale (VRS) at 6 and 12 h; trauma to the gingival tissues, sealing ability of the clamp, and slippage of the clamp were evaluated using criteria for clinical evaluation of rubber dam isolation., Statistical Analysis Used: Independent t -test and Chi-square test were used to compare VRS and clinical parameters, respectively, with P < 0.05., Results: Gingival trauma ( P = 0.006) and postoperative pain were statistically significantly more in the wingless group at 6 h ( P = 0.016) and 12 h (0.01). Statistically significant lower seepage of fluid ( P = 0.017) was observed in the wingless group. Slippage was observed more with the winged group but was statistically insignificant., Conclusion: Both clamps showed acceptable clinical performance. Their use should be planned as per the requisite of the case and the position of the tooth., Competing Interests: There are no conflicts of interest., (Copyright: © 2023 Journal of Conservative Dentistry.)

Introduction: This study's objective was to assess and compare postoperative pain response between bioceramic sealer (Nishika BG) and epoxy resin based (AH Plus) in patients with primary endodontic lesion at time interval of 24 h, 48 h, and 7 days using the Visual Analog Scale (VAS)., Materials and Methods: The study included 40 individuals with necrotic pulp and apical periodontitis. Calcium hydroxide was administered as the intracanal medication during the two-visit endodontic therapy. They were subsequently allocated randomly to either the AH Plus root canal sealer or the Nishika Canal Sealer BG, with a total of 20 participants in each group. Patients were told to use a VAS to rate their postoperative pain severity as none, minimal, moderate, or severe after 24 h, 48 h, and 7 days following obturation using the appropriate sealers., Results: Nishika Canal Sealer BG (CS-BG) has a lower pain score as compared to the AH Plus group at 24-h time point. VAS ratings for both the groups decreased over time. According to the intergroup analysis, there was a significant difference in postoperative pain at the 24 h ( P = 0.022), but not at the 48 h or 7 days ( P > 0.05)., Conclusion: Although bioceramic sealer (Nishika Canal Sealer BG) resulted in significantly lower levels of pain as compared to epoxy resin-based sealer (AH Plus) at 24-h interval, there was no significant difference of postoperative pain at 48-h interval and 7-day period., Competing Interests: There are no conflicts of interest., (Copyright: © 2023 Journal of Conservative Dentistry.)

Elimination of bacteria from infected root canal systems is a challenging task. Various techniques have been described to reduce the number of bacteria within the root canal system, which include chemomechanical instrumentation, use of various irrigants to remove or dissolve organic and inorganic debris, and to destroy bacteria. The intracanal medicament plays a key role in the success of root canal treatment. With the rise in bacterial resistance to antibiotics, there is considerable interest in the development of other classes of antimicrobials for the control of infection. Natural products are known to play an important role in human life. The use of herbal products as mouthwash has been tried and tested in the literature. However, the use of herbal intracanal medicament has been shown promising results when used under in vitro conditions, but in vivo studies are very scarce. This may be due to the limited supporting literature available to use it as intracanal medicament in patients due to the ethical concern. Hence, the purpose of this review is to highlight the current guidelines (laid by the drugs and cosmetics act as per the Gazette of India) regarding the use of herbal medicaments for the clinical trials in endodontics., Competing Interests: There are no conflicts of interest., (Copyright: © 2020 Journal of Conservative Dentistry.)

Aim: The present study aimed to compare the remaining dentin thickness (RDT) and fracture resistance of conventional and conservative access and biomechanical preparation in molars using cone-beam computed tomography (CBCT)., Methodology: A total of 60 freshly extracted human molars were selected and were randomly divided into two groups of conventional and conservative access preparation group ( n = 30). Samples were subjected to pre-CBCT scan at the pericervical region for the measurement of total dentin thickness. For the conventional group, samples were accessed and biomechanical preparation was done using K3 XF file. For conservative group, samples were accessed using CK microendodontic burs using a dental operating microscope and biomechanical preparation was done using self-adjusting file. After obturation and postobturation with nanohybrid composite restoration, samples of both groups were subjected to post-CBCT scan at pericervical region for the measurement of RDT. The samples were then loaded to fracture in the Instron Universal Testing Machine, and the data were analyzed using paired sample t -test and independent sample t -test., Results: The mean RDT was less in conventional group than conservative group. Pericervical dentin was preserved more in conservative group. The statistical difference among both the experimental group was highly significant (<0.001). The mean load at fracture was less in conventional group than conservative group (<0.001)., Conclusion: Coronal dentin was conserved in molars when accessed through conservative than through conventional. The dentin conservation afforded an increased resistance to fracture in conservative group which is doubled the fracture resistance in conventional group., Competing Interests: There are no conflicts of interest.

Introduction: This systematic review intended to compare the biocompatibility and sealing ability of mineral trioxide aggregate (MTA) and biodentine as root-end filling material., Materials and Methods: A computerized literature search was performed on March 1, 2016, in MEDLINE, PubMed, and COCHRANE LIBRARY for data published from January 2011 to March 2016. Quality assessment of the selected studies was performed according to the PRISMA guidelines, 2009., Results: A total of 12 in vitro studies were included in this review. Of these, four studies compared the biocompatibility and eight compared the sealing ability. With regard to biocompatibility, two articles showed biodentine to be better and two showed comparable results, while in the case of sealing ability, one article showed MTA to be better, six articles showed biodentine to be better, and the rest one article showed the comparable result., Conclusion: It may be concluded that good sealing ability of biodentine along with its favorable biological properties show that materials can be used competently in clinical practice as a retrograde filling material. However, long-term assessment in clinical situations is necessary for further inferences., Competing Interests: There are no conflicts of interest.
