    Prediction of spontaneous eruption of palatally displaced canine based on variables measurements in panoramic radiograph: A systematic review
    (Elsevier B.V., 2021) Shukla, Neeteesh K.; Sharma, Vipul K.; Chaturvedi, T.P.; Parihar, Ajit V.; Chugh, Vinay K.
    Objective: This systematic review was aimed to find out possible predictive variables measured on panoramic radiographs to predict spontaneous eruption of palatally displaced canine (PDC) after interceptive extraction in late mixed dentition. Materials and methods: Electronic database searches were performed in MEDLINE, Cochrane's CENTRAL, Scopus, and in other sources up to June 2020. Randomized and nonrandomized controlled trials, and pre-post prospective studies without control groups were considered for review. Study selection, data extraction, risk of bias assessment (by RoB 2.0, ROBINS-I, and NHLBI score), and the certainty of evidence evaluation (GRADE approach) were performed during reviewing process. Only qualitative analyses of included literature were done due to presence of between study heterogeneity. Results: Out of 970 retrieved records, 3 controlled trials and 3 prospective before and after studies without control fulfilled the eligibility criteria and were included in the review. Studies were assessed at low risk to high risk of bias. Overall certainty was moderate to very low. Results shows that PDCs in distal sectors, lower alpha angle, younger subjects, PDCs with less advanced developed root were significantly benefited from interceptive extraction. However, Vertical distance had insignificant roll on eruption prediction. Conclusions: Interceptive extraction at younger age, mesial canine crown position (sectors), and mesial inclination of PDC (alpha angulation) are the most important variables predicting the spontaneous eruption of palatally displaced canine. Findings of this review can be utilized to make evidence-based decisions for managing PDCs with diverse sectors and mesial inclinations. However, well designed clinical trials are recommended to strengthen the evidence. � 2021

    The effect of various nanoparticle coating on the frictional resistance at orthodontic wire and bracket interface: A systematic review
    (Wolters Kluwer Medknow Publications, 2022) Indumathi, P.; Singh, Deepak; Sharma, Vipul K.; Shukla, Neeteesh K.; Chaturvedi, T.P.
    This systematic review was aimed to test the null hypothesis that coating of orthodontic wires with nanoparticles does not affect the frictional properties at bracket-wire interface. Electronic database searches were performed up to September 2020. In vitro studies were considered for reviewing process. Study selection, data extraction, risk of bias assessment was performed during reviewing process. Only qualitative analyses of included literature were done due to the presence of heterogeneity among the studies. Out of 1,068 retrieved records, nine studies satisfied the inclusion criteria and included in this review. Studies were assessed at low risk to high risk of bias according to certain parameters. Wide variety of nanoparticles were used for surface coating of orthodontic wires of variable sizes, shapes, and materials like stainless steel, NiTi, and TMA and placed into the slots of different types of orthodontic brackets to evaluate the alteration in frictional and other mechanical properties. Most of the studies clearly indicate that coating with nanoparticles decreases the friction between wire and bracket interface under specified in vitro conditions. Furthermore, among the nine included studies, only two considered evaluation of effect of coated brackets on frictional and other mechanical properties and results were heterogeneous. The null hypothesis is rejected and it is concluded that the wires coated with nanoparticles might offer a novel opportunity to substantially reduce frictional resistance at bracket-wire interface during tooth movement. Further studies are necessary to strengthen the evidence regarding effect of coated brackets on frictional properties. � 2022 Journal of Research in Medical Sciences Published by Wolters Kluwer-Medknow.

    White spot lesions in clear aligner therapy as compared with multi-bracket system: A Systematic Review
    (IP Innovative Publication Pvt. Ltd., 2023) Singh, Deepak; Sharma, Vipul K.; Srivastava, Roopal; Priyadarshani, Pooja; Chaturvedi, T.P.
    Aim and O bjective: To evaluate incidence of white spot lesions in clear aligner treatment compared with fixed appliance therapy. Materials and Methods: Electronic databases (PubMed, Cochrane Collaboration Oral Health group database of clinical trials, Web of Science, Science Direct, Scopus) and manual search of gray literature were conducted up to September 2021. Both randomized and non-randomized controlled studies were considered for review purposes. Study selection, data extraction, quality assessment (RoB 2.0 and ROBINS-I) was performed according to the Cochrane Handbook for Systematic Reviews of Intervention. Due to the presence of high heterogeneity only qualitative analysis has been done. Results: Out of 479 retrieved literature, 3 studies fulfilled the eligibility criteria and were included in the analysis. Studies were evaluated at low to high risk of bias. On qualitative analysis, a total of 160 new white spot lesions were developed in the clear aligner group and 362 new lesions were found in the fixed orthodontic group (P <0.001). In addition, the surface area of white spot lesion in the clear aligner group was more than the fixed appliance group but the deepest lesion was still found in the fixed appliance group. Conclusion: Incidence and severity of white spot lesion was found more in the fixed appliance group as compared to the clear aligner group. However, more low risk of bias studies with proper methodological quality is required to reinforce the conclusive evidence. � 2023 Author(s).
