    A rare incidence and management of complex odontoma and surgical dehiscence in maxillary anterior region: A case report
    (Wolters Kluwer Medknow Publications, 2023) Gupta, Sakshi; Mittal, Neelam; Shankari, Thivya; Gupta, Supriya
    Odontoma is a benign odontogenic tumour, which is rather considered hamartoma. Hamartoma is not a true neoplasm, rather a growth of abnormal mixture of cells found in the body area they normally grows. Fully developed odontomas generally consist of enamel, dentin and pulpal tissues, in an unorganised manner. Some of them may contain cementum too. These are further grouped into compound and complex, depending on their clinical, radiographic and histologic features. Odontomas are generally asymptomatic and slow growing, but may cause bone expansion and hinderance in tooth eruption. These lesions are generally diagnosed by coincidence in radiograph. We are presenting a case and surgical management of complex odontoma and post?operative dehiscence in the anterior right maxillary region of a 38?year?old male. � 2023 National Journal of Maxillofacial Surgery.

    Assessment of pulp sensibility in the mature necrotic teeth using regenerative endodontic therapy with various scaffolds - Randomised clinical trial
    (Wolters Kluwer Medknow Publications, 2021) Mittal, Neelam; Baranwal, Harakh C.; Kumar, Praveen; Gupta, Sakshi
    Aim: This study aimed to evaluate and compare the possibility of regaining pulp sensibility and objectives of regeneration procedure in mature necrotic teeth using regenerative endodontics. Materials and Methods: A total of 36 mature necrotic teeth were selected and a regenerative endodontic procedure was performed. A total of four groups, each involving n = 9 teeth per group were randomly grouped as (1) periapical bleeding, (2) platelet-rich fibrin (PRF), (3) collagen, and (4) hydroxyapatite. Pulp testing and radiographic assessment of periapical healing (PH) were recorded at every 3-month interval for 1 year. Readings were compared as qualitative data using the Kruskal-Wallis test to see the inter-group significant difference. Results: Readings of pulp sensibility revealed non-significant results in all intervals. At 3 and 6 months, 22.3% in the PRF group and 11.15% in collagen group; and at 9 months, 44.4% in PRF group, 33.3% in the collagen group and 22.2% in hydroxyapatite group; and at 12-months, 66.6% in PRF, 44.4% in the collagen group, 33.3% in the hydroxyapatite group and 11.1% in the periapical bleeding group showed a positive response to the cold test. But all groups did not show a positive response to heat and electric pulp testing and showed good PH in all groups at the end of 12 months. Conclusions: The presence of sensibility to cold test is indicative of the formation of vital pulp-like tissues, which was the highest in the PRF group, followed by the collagen, hydroxyapatite and periapical bleeding groups. � 2021 Indian Journal of Dental Research Published by Wolters Kluwer - Medknow.

    Comparative analysis of reduction in pain scores after single visit root canal treatment using endodontic irrigation protocols, namely, Conventional needle irrigation, PUI, PIPS and SWEEPS: A randomized control trial
    (Wolters Kluwer Medknow Publications, 2023) Mittal, Neelam; Baranwal, Harakh Chand; Gupta, Sakshi; Shankari, Thivya; Gupta, Supriya; Kharat, Shubham
    Introduction: To assess the effects of different irrigation activation systems on postoperative pain using a Visual Analog Scale (VAS), using new laser irrigation activation system shock wave-enhanced emission photoacoustic streaming (SWEEPS), photon-induced photoacoustic streaming (PIPS), passive ultrasonic irrigation activation techniques, compared with the conventional irrigation (CI) method. Materials and Methods: Sixty patients suffering from symptomatic irreversible pulpitis in maxillary or mandibular molars were enrolled and randomly assigned to four different irrigation activation groups (n = 15) after chemomechanical root canal preparation. Preoperative and postoperative pain scores were recorded using VAS. The data were collected and subjected to statistical analysis using IBM SPSS 20.0 software at a level of significance being 0.05. Results: We observed that mean pain scores decreased with time in all patients in all groups. The decrease in pain score was found to be statistically significant (P < 0.05) among both the genders in Group 3 (PIPS) and Group 4 (SWEEPS). Postoperatively, pain scores decreased significantly using Group 4 (SWEEPS), followed by Group 3 (PIPS), Group 2 (ultrasonic activation), and Group 1 (conventional needle irrigation). No significant relation was observed statistically between pain scores and age groups among all groups, except for preoperative score in Group 3 and age groups. Conclusion: Postoperative scores were lower in laser-activated irrigation systems as compared to the other activation systems. The highest pain scores were observed in case of CI method, at pre- and post-operative periods. � 2023 Journal of Conservative Dentistry | Published by Wolters Kluwer - Medknow .

    Comparative evaluation of bioglass nanofiber, dexamethasone-coated bioglass nanofiber, and platelet-rich fibrin, as scaffolds in regenerative endodontic treatment of immature necrotic teeth: A randomized controlled trial
    (Wolters Kluwer Medknow Publications, 2022) Gupta, Sakshi; Mittal, Neelam; Baranwal, Harakh Chand; Rath, Chandana; Shankari, Thivya; Gupta, Supriya
    Aim: The aim of this study was to evaluate and compare the regenerative endodontic potential of dexamethasone-coated bioglass nanofiber (Dex-BGnf), bioglass nanofiber (BGnf), and platelet-rich fibrin (PRF) for inducing regeneration in necrotic immature permanent teeth. Materials and Methods: A total of 36 (n = 12) immature necrotic teeth with or without evidence of periapical lesion were included in the study. Patients were randomly allocated into three groups, based on the scaffolds used: Group I (PRF), II (BGnf), and III (Dex-BGnf). The clinical (electric pulp test) and radiographic evaluations (percentage increase in apical diameter, root length, root dentin thickness, and periapical healing) were compared at 6 and 12 months after the procedure with baseline records. Statistical Analysis: One-way ANOVA, post hoc Tukey analysis, and Kruskal-Wallis test were used for evaluating the data. A 6- and 12-month improvement analysis was done using paired t-test and Friedman test. Results: Clinically, all the 36 teeth were asymptomatic, but none gave a positive response to Electric Pulp Test (EPT) in time interval of 12 months. Dex-BGnf showed a statistically significant improvement in terms of increase in root length (P = 0.020) and root dentinal thickness (P = 0.001) when compared to PRF after 12 months. Conclusion: The study has shown that Dex-BGnf yielded significantly better results than PRF for inducing apexogenesis in necrotic immature teeth. � 2022 Wolters Kluwer Medknow Publications.

    Comparative evaluation of retreatability of bioceramic sealer (BioRoot RCS) and epoxy resin (AH Plus) sealer with two different retreatment files: An in vitro study
    (Wolters Kluwer Medknow Publications, 2021) Baranwal, Harakh Chand; Mittal, Neelam; Garg, Riya; Yadav, Jyoti; Rani, Prachi
    Aim: The aim of the study was to evaluate and compare the retreatability of BioRoot RCS and AH Plus sealer with two different retreatment file systems using cone-beam computed tomography (CBCT) for assessing the filling remnants. Materials and Methods: A total of sixty mandibular premolars with single and oval root canals were prepared till size F3 and obturated with GP/AH Plus (Group 1) and GP/BioRoot RCS (Group 2). Canals were then retreated using two different retreatment file systems-ProTaper Universal Retreatment (PTUR) system and NeoEndo Retreatment system. The ability to re-establish working length (WL) and apical patency was recorded, and the percentage volume of residual filling material was evaluated using CBCT at the coronal, middle, and apical thirds. Data from the study were analyzed using one-way analysis of variance with Pearson's Chi-squared analysis and the Kruskal-Wallis test. Results: No statistically significant difference was found in the amount of residual sealer (AH Plus and BioRoot RCS) after retreatment throughout the whole study (P > 0.05) at various root canal levels. Furthermore, the BioRoot RCS group retreated with the PTUR system showed a higher frequency of failure in re-establishing WL and regaining apical patency than the other groups. Conclusion: Complete removal of root canal sealers could not be achieved regardless of the type of sealer used and the retreatment technique employed. Furthermore, in clinical settings, the retreatability of novel BioRoot RCS may be deemed feasible. � 2021 Journal of Conservative Dentistry Published by Wolters Kluwer-Medknow.

    Comparison of Dentinal Defects Induced by Rotary, Reciprocating, and Hand Files in Oval Shaped Root Canal - An In-Vitro Study
    (Wolters Kluwer Medknow Publications, 2023) Branawal, Harakh Chand; Mittal, Neelam; Rani, Prachi; Ayubi, Aiyman; Samad, Silviya
    Aim: To evaluate and compare the formation of dentinal defects using hand Hedstrom files, XP-Shaper, TruNatomy, and Reciproc Blue file systems when used for oval shaped root canals. Materials and Methods: One hundred and five extracted human mandibular premolars with single root and oval canals were selected for the study. Twenty-one teeth were unprepared (control), and the remaining teeth were divided into the prepared groups (n = 21), that is, Group H-Files, Group XP-Shaper, Group TruNatomy, and Group Reciproc Blue. All selected teeth were de-coronated perpendicular to the long axis of the tooth by using a diamond-coated disk with water cooling, leaving root segments approximately 16 mm in length. Each group was prepared according to the above file system. Then all roots were sectioned perpendicular to their long axes at 3, 6, and 9 mm from the apex using a diamond-coated disk under a continuous water stream. Each specimen was then checked for the presence of dentinal defects/microcracks. Result: The XP-Endo shaper group had the lowest number of defects (01/21 roots) 4.7%; TN (04/21) 19%, H-Files (04/21) 19%, and RC Blue (05/21) 23.8% had the highest incidence of defects. However, no significant difference was detected among these groups (P > 0.05). Conclusion: The motor-driven root canal instrumentation with rotary and reciprocating files and hand files may create microcracks in the radicular dentine, whereas the XP-Shaper file system produces minimal or less cracks compared to other tested rotary file systems and H-file instrumentation. � 2024 Indian Journal of Dental Research.

    Evaluation of the effect of nonsurgical periodontal therapy on malondialdehyde and 8-hydroxy deoxyguanosine levels in chronic periodontitis
    (Wolters Kluwer Medknow Publications, 2022) Gautam, Anju; Mittal, Neelam; Mishra, Surendra Pratap; Singh, Tej Bali; Chandra, Akhilesh
    Background: Reactive oxygen species released on stimulation by periodontal pathogens cause oxidation of biomolecules and play significant role in periodontal disease pathogenesis. Aim: This study aimed to evaluate the levels of oxidative by-products malondialdehyde (MDA) and 8-hydroxy deoxyguanosine (8-OHdG) as biomarkers in chronic periodontitis patients compared to healthy as well as before and after nonsurgical periodontal therapy. The correlation between biomarkers and clinical attachment level was also evaluated. Settings and Design: A total of 112 subjects were included in this study. The subjects were divided into two groups (Group I included 56 healthy subjects and Group II constituted 56 chronic periodontitis patients) on the basis of clinical periodontal parameters. Materials and Methods: Group I subjects received no treatment and were evaluated once only for clinical and oxidative stress biomarker parameters. Nonsurgical periodontal therapy was carried out in Group II patients and they were evaluated at baseline and 3 months after therapy. Results: Both salivary and serum levels of MDA and 8-OHdG were found to be increased in chronic periodontitis patients as compared to healthy subjects. After nonsurgical periodontal therapy, the levels of MDA and 8-OHdG significantly reduced. Linear correlation between clinical attachment level and oxidative stress parameters was found to be positive and highly significant. Conclusion: It can be concluded that periodontal therapy is effective in improving the oxidative stress condition. � 2022 Wolters Kluwer Medknow Publications. All rights reserved.

    Management of Cracked Maxillary First Molar with Erbium?Doped Yttrium Aluminum Garnet Laser
    (Wolters Kluwer Medknow Publications, 2022) Mittal, Neelam; Gupta, Supriya; Gupta, Sakshi; Shankari, Thivya
    Treatment and diagnosis of fractured teeth present a big challenge to dentists. Treatment of traumatized teeth can be done with reattachment of a dental fragment both in simple and complicated coronal fractures. A 28-year-old male patient came to our department with a traumatic crown fracture of the permanent, left maxillary molar. The patient complained of pain upon mastication, and on examination left maxillary second molar has a fracture line extending in a mesiodistal direction. Partial pulpotomy with the help of erbium-doped yttrium aluminum garnet (Er: YAG) laser was done to relieve symptoms and to reduce microleakage and increase strength, the fracture line was sealed with the help of Er: YAG laser. The cavity was then sealed with biodentin and composite. For these types of cases, Er: YAG laser is used for biostimulation of exposed pulp, and also to improve strength and reduce microleakage through sealing of fracture line. � 2022 Journal of Interdisciplinary Dentistry.

    Outcome of partial pulpotomy verses full pulpotomy using biodentine in vital mature permanent molar with clinical symptoms indicative of irreversible pulpitis: A randomized clinical trial
    (Wolters Kluwer Medknow Publications, 2022) Baranwal, Harakh; Mittal, Neelam; Yadav, Jyoti; Rani, Prachi; Kumar, Naveen
    Aim: The aim of the study is to evaluate and compare the clinical and radiographic outcome of partial pulpotomy and full pulpotomy in mature permanent molars with symptomatic irreversible pulpitis using biodentine. Materials and Methods: A total of 66 vital mature permanent molars with irreversible pulpitis were randomly allocated to a partial pulpotomy (n = 33) and full pulpotomy group (n = 33). Biodentine was used as a pulp capping material which was covered with resin-modified glass ionomer cement (RMGIC) followed by composite restoration. Clinical and radiographic evaluation was done at 3, 6, and 12 months follow-up for tenderness, periapical radiolucency, dentine bridge formation, and root canal calcification. Data from the study were analyzed using a Friedman and Mann-Whitney test and the success rate was analyzed by Chi-square value. Result: No statistically significant difference was found between partial and full pulpotomy (P > 0.05) and the success rate was 80.7% and 92.8%, respectively, at 12 months follow-up period. Conclusion: Both partial and full pulpotomy can be used as a permanent treatment modality in symptomatic irreversible pulpitis of vital mature permanent molars. � 2022 Wolters Kluwer Medknow Publications.
