RESUMO
AIM: The main objective of this systematic review is to comprehensively evaluate all the relevant studies to evaluate the effectiveness of electrical stimulation to accelerate orthodontic tooth movement in human patients. METHODS: Using a suitable search strategy, various databases like PubMed, CENTRAL, Scopus and Google Scholar were surveyed for relevant randomized controlled trials (RCTs); after which a hand search of related orthodontic journals was completed. The risk of bias of studies was checked using Cochrane's ROB-2 tool. The quality of evidence of the included studies was evaluated using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) framework. Rate of orthodontic tooth movement was compared and thus efficiency of electrical stimulation to accelerate tooth movement was assessed. Meta-analysis was done on 2 studies out of the 4; rate of orthodontic tooth movement was compared at two time periods after start of treatment (3rd month and 5th month) with standardized mean difference (SMD) as summary estimate, with p < 0.05 denoting statistical significance. Publication bias was checked using a funnel plot. RESULTS: Via exploration of the online databases and hand searching, 1080 studies were found after removing duplicates. After full text assessment, 13 studies in total were selected that used electrical stimulation, out of which 4 studies were included in the qualitative analysis as they met the inclusion criteria. The meta-analysis was done for 3rd month and 5th month with SMD as 0.69(-1.26-0.12) and 1.64(-3.44-0.16), respectively. The strength of evidence in the meta-analysis is moderate. There was no publication bias as shown by funnel plot. DISCUSSION: The studies included showed increased risk of selection and performance bias. Also due to the limited number of studies available, there was difficulty in reaching definitive conclusions. The meta-analysis showed a significant difference among the control and experimental group for the 3rd month. CONCLUSION: Even though a positive correlation is found between electrical stimulation and acceleration of orthodontic tooth movement, it is advised to conduct further studies, particularly with human participants, to establish a more conclusive outcome. REGISTRATION: This review has received no funding. The protocol for the study was registered in the Prospective Registration of Systematic Review (PROSPERO)(CRD42023495077).
RESUMO
BACKGROUND: This systematic review aimedto evaluate the remineralizing efficacy of calcium sucrose phosphate (CaSP) for the treatment of white spot lesions (WSLs) that commonly occur after orthodontic treatment with fixed appliances using various randomized controlled trials (RCTs) available in the literature todate. HIGHLIGHTS: Adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA) guidelines, RCTs that assessed the efficacious remineralizing potential of CaSP on WSLs and demineralized enamel and compared it with either no intervention or other remineralizing agents wereselected. The methodological rigor of the included studies was subjected to the Risk of Bias tool-2 (ROB-2) and Grading of Recommendations, Assessment, Development and Evaluation (GRADE) tools. Furthermore, a Begg's Funnel Plot was used to assess publication bias. The qualitative analysis encompassed a corpus of 36 studies. The remineralization potential of CaSP was investigated using an array of parameters, including surface microhardness, surface morphology, surface roughness, mineral content, and lesion size and depth. Based on the ROB-2 tool, most of the included studies were judged to be high risk, largely attributable to the presence of attrition bias. Using the GRADE framework, the certainty of evidence was determined to be moderate. CONCLUSION: This systematic review reveals that CaSP yields favorableoutcomes in terms of increased surface microhardness and calcium-phosphate content, reduced demineralized area and surface roughness, and enhanced surface topography.

AIM: The aim of this study was to evaluate specific single nucleotide polymorphisms (SNP) of transforming growth factor-beta (TGF-ß) (rs1800469) and insulin-like growth factor-1 (IGF-1) (rs17032362) genes in Class II individuals with a normal maxilla and retrognathic (short) mandible.
