clinical application of casein phosphopeptide amorphic calcium phosphate in preventing enamel decalcification in Orthodontics
Chinese Journal of Orthodontics, 2011Co-Authors: J Wang, Yan Yan, Xiujing Wang, S U QizhiAbstract:Objective To evaluate the preventive effect of Casein Phosphopeptide-Amorphic Calcium Phosphate (CPP-ACP)in reducing enamel decalcification in Orthodontics.Methods Sixty orthodontic patients were divided into trial group and control group randomly.Patients in trial group were given oral hygiene education and GC tooth protector (mainly CPP-ACP).Patients in control group were given oral hygiene education only.Pictures were taken and the extents of enamel decalcification between two the groups were compared one year after orthodontic treatment.Results The decalcification index in trial group was 0.019 ± 0.033 and that in control group was 0.067 ± 0.039.The difference was significant (F=9.1,P＜0.01).Conclusions Casein PhosphopeptideAmorphic Calcium Phosphate could prevent enamel decalcification in Orthodontics.

clinical evaluation of remineralization potential of casein phosphopeptide amorphous calcium phosphate nanocomplexes for enamel decalcification in Orthodontics
Chinese Medical Journal, 2012Co-Authors: J Wang, Yan Yan, Xiujing WangAbstract:Background: Enamel decalcification in Orthodontics is a concern for dentists and methods to remineralize these lesions are the focus of intense research. The aim of this study was to evaluate the remineralizing effect of casein phosphopeptide amorphous calcium phosphate (CPP-ACP) nanocomplexes on enamel decalcification in Orthodontics. Methods: Twenty orthodontic patients with decalcified enamel lesions during fixed orthodontic therapy were recruited to this study as test group and twenty orthodontic patients with the similar condition as control group. GC Tooth Mousse, the main component of which is CPP-ACP, was used by each patient of test group every night after tooth-brushing for six months. For control group, each patient was asked to brush teeth with toothpaste containing 1100 parts per million (ppm) of fluoride twice a day. Standardized intraoral images were taken for all patients and the extent of enamel decalcification was evaluated before and after treatment over this study period. Measurements were statistically compared by t test. Results: After using CPP-ACP for six months, the enamel decalcification index (EDI) of all patients had decreased; the mean EDI before using CPP-ACP was 0.191 ± 0.025 and that after using CPP-ACP was 0.183 ± 0.023, the difference was significant (t = 5.169, P 0.05). Conclusion: CPP-ACP can effectively improve the demineralized enamel lesions during orthodontic treatment, so it has some remineralization potential for enamel decalcification in Orthodontics.

the application of orthodontic miniplates to sendai surgery first
Seminars in Orthodontics, 2018Co-Authors: Junji Sugawara, Hiroshi Nagasaka, Satoshi Yamada, So Yokota, Tetsu Takahashi, Ravindra NandaAbstract:Current Surgery First (SF) approaches can be classified into two rather different styles. One is the orthodontic-driven style. In this style, skeletal problems are solved by surgery, and dental problems are fixed orthodontically. The other is the surgery-driven style. In this approach, the aim is to solve both skeletal and dental problems by orthognathic surgery (OGS) as much as possible. The concept of SF that we practice is the orthodontic-driven style, referred to as Sendai SF (SSF). This approach was made possible by the application of the Skeletal Anchorage System (SAS) which enables predictable control of the entire dentition, including the three-dimensional control of the bimaxillary molars. With SAS in combination with the multi-bracketed system, the extent of surgical intervention is significantly reduced, and complex orthodontic problems in post-surgical Orthodontics can be solved. In this article, the SAS biomechanics of the post-surgical Orthodontics in SSF is described.

efficiency of piezotome corticision assisted Orthodontics in alleviating mandibular anterior crowding a randomized controlled clinical trial
European Journal of Ophthalmology, 2017Co-Authors: Flavio Uribe, Leyla Davoody, Rana Mehr, Yasas S N Jayaratne, Khalid Almas, Takanori Sobue, Veerasathpurush Allareddy, Ravindra NandaAbstract:Objectives The aim of this clinical trial was to investigate the duration of mandibular-crowding alleviation with piezotome-corticision Orthodontics compared with conventional Orthodontics. Design Single-centre, two-arm parallel group randomized controlled trial. Setting Orthodontic clinic at the University of Connecticut. Ethical approval The study was approved by the Institutional Review Board (IRB # 12-0147-2). Subjects and methods Forty-one adult subjects from a single centre with more than 5mm of mandibular anterior crowding were randomly allocated using block randomization into experimental and control groups. The experimental group received a corticision procedure with a piezotome on the labial aspect of the mandibular incisors in conjunction to a self-ligation fixed orthodontic appliance. The control group received the self-ligation fixed orthodontic appliance and no corticision. Same archwire sequence (0.014 inch followed by 0.014 × 0.025 inch copper-nickel-titanium) was followed for both groups. Mandibular study casts taken every 4-5 weeks were used to assess changes in the irregularity index by blinded outcome assessors. Outcome measures The time to alignment was calculated in days. Results Twenty-nine subjects (16 experimental and 13 control) completed the study. Overall, no significant difference in the time required to correct mandibular crowding with piezotome-corticision assisted (102.1 ± 34.7 days; 95% CI, 83.6 to 120.6) and conventional Orthodontics (112 ± 46.2 days; 95% CI, 84-139.9) was observed. No complications with treatment or unintended consequences were observed on any of the subjects. Limitations A high attrition rate. Conclusions This randomized clinical trial found no evidence that piezotome-corticision assisted Orthodontics was more efficient in alleviating mandibular anterior crowding. Registration ClinicalTrials.gov, Identifier: NCT02026258. Funding Division of Orthodontics, University of Connecticut. Conflict of Interest None.
