Objective: To compare the rate of accelerated tooth movement in canine retraction with micro-osteoperforation on one side and control on the other. Study Design: Quasi experimental study. Place and Duration of Study: Orthodontics department, Armed Forces Institute of Dentistry, Rawalpindi Pakistan, from Jul 2018 to Jan 2019. Methodology: A total of 30 patients were inducted. After alignment and extraction of maxillary first premolars, canine retraction was started with closed NiTi coil spring on both sides of the maxillary arch. Micro-osteoperforation was done on the right side and other side was a control side. The distance between the lateral incisor and the canine was measured on both sides before micro-osteoperforation. The same measurements were recorded after three weeks of retraction. The difference between pre and post retraction measurements was recorded. The difference in the rate of canine retraction between both modalities was compared using independent sample t-test. Results: The study included 17 males (56%) and 13 females (43%). The mean rate of tooth movement at experimental side of maxilla was 1.6 ± 0.52 mm and on control side was 0.66 ± 0.31 mm (p<0.05). Conclusion: Micro-osteoperforation was an effective, comfortable, and safe procedure to accelerate tooth movement (1.6 times in accordance with this study). It significantly shorten the duration of orthodontic treatment.

AIM: The aim of the study was to investigate the effectiveness of using micro-osteoperforations (MOPs) or piezocision in accelerating tooth movement, during canine retraction, compared to standard canine retraction. PATIENTS AND METHODS: A split-mouth study design was carried out with two Groups A and B. Each group contained 10 patients; in each patient, one side was used as a control side and the contralateral side received either MOPs (Group A) or piezocision (Group B). The assessment data were collected by direct intraoral measurements, every 2 weeks, over a 3 months retraction period. RESULTS: Independent t-test, paired t-test, and ANOVA were used to analyze the results. In Group A, there was a statistically significant difference between the study and control sides (p < 0.001) with a total of 4.2 ± 0.5 mm canine retraction in the MOPs assisted canine retraction side versus a 2.8 ± 0.2 mm total canine retraction in the control side. For Group B, there was a statistically significant difference between the study and control sides (p < 0.001) with a total of 3.6 ± 0.4 mm canine retraction in the piezocision-assisted canine retraction side versus a 2.8 ± 0.2 mm total canine retraction in the control. CONCLUSION: MOPs and piezocision techniques accelerated the rate of canine retraction during orthodontic treatment, with the MOPs being slightly more effective.

ABSTRACT Objectives To evaluate the effects of submucosally administered platelet-rich plasma (PRP) on the rate of maxillary canine retraction. Levels of soluble receptor activator of nuclear factor-κb ligand (sRANKL) and osteoprotegerin (OPG) in the gingival crevicular fluid (GCF) were also measured over 2 months. Materials and Methods This split-mouth trial involved 20 sites in 10 subjects randomly assigned to PRP (experimental) side and control side. After alignment, the freshly prepared PRP was injected submucosally distal to the experimental side maxillary canine, and retraction was performed using NiTi closed-coil springs (150 g) on 0.019 × 0.025-inch stainless steel wire. The rate of canine movement was assessed using digital model superimposition at 0, 30, and 60 days. The OPG and sRANKL were assayed using enzyme-linked immunosorbent assay from GCF collected at 0, 1, 7, 21, 30, and 60 days. Results Twenty sites were analyzed using paired t test. The rate of tooth movement increased significantly by 35% on the PRP side compared with the control side in the first month (P = .0001) and by 14% at the end of the second month (P = .015). Using the Mann–Whitney U test, OPG levels were found to be significantly decreased on the 7th (P = .003) and 30th day on the PRP side (P = .01), while sRANKL became detectable by the third week postinjection on the PRP side (P = .069). Conclusions Submucosal injection of platelet-rich plasma significantly increased tooth movement during the 60-day observation period. Local injection of PRP significantly altered the levels of OPG and sRANKL in GCF.

The effect of water-soluble components of extra-old Cheddar cheese on experimental caries was tested by means of the seven-day intraoral cariogenicity test (ICT). Two bovine enamel blocks were placed in each buccal flange of the dental appliances of five volunteers. One side of each appliance (experimental) was dipped in a 25% water extract of the cheese for five min, while the other side (control) was dipped in de-ionized water. Immediately thereafter, the appliance was returned to the subject's mouth, and two 60-second rinses with 10% sucrose were performed. These procedures were repeated six times per day. The cheese-extract dippings reduced the cariogenicity of the sucrose by an average of 55.7% (p<0.01), as assessed by enamel microhardness. Neither the mean resting pH nor the mean minimum pH in response to sucrose was significantly different between the experimental and control sides. The concentration of calcium was significantly higher in plaque from the experimental side (32.44 μg/mg) as compared with the control side (19.36 μg/mg, p<0.01). The concentration of plaque phosphorus was higher on the experimental side (12.90 μg/mg) than on the control side (9.61 μg/mg); however, the difference was not statistically significant. These results show that cheese has one or more water-soluble components which reduce experimental caries in human subjects.

Introduction. Various procedures are available today to enhance tooth movement, with relative success rates, one among them being Micro Osteo Perforation (MOP). Our aim is to assess the rate of tooth movement and interleukin 1β levels in gingival crevicular fluid levels (GCF)after MOPs. Methodology. A group of 22 patients were selected, who required first premolars extraction  and were designated for the split mouth study with equal allocation. MOP was performed on the right side, three vertical MOPs were given using 1.2 X 8 mm mini implants with the gap of 2 mm between them and surgical depth of the implant insertion was 5 mm. The left side was used as control. The individual canine retraction was initiated with placement of 150 grams on 19*25 SS wire. The case was evaluated at different timelines for canine retraction and Interleukin 1β levels. Results. There was a significant difference in the rate of canine movement at 45 days (1.42 mm) and end of canine retraction on experimental side(2.61 mm). The GCF levels were raised at T1 and T2 intervals on the side of MOP and were statically significant (p=0.00). Conclusion. MOP is a minimally invasive procedure which accelerates the tooth movement by 20%. The increase in IL 1βlevels indicates a higher rate of chemical interaction on the surgically assisted side. For enhanced efficiency MOPs should be repeated every 6-8 weeks.
