Abstract Objective: The aim of this study was to evaluate a flapless surgical technique as an alternative to traditional alveolar corticotomy used to accelerate orthodontic tooth movement (OTM). Methods: To induce OTM in Wistar rats, 40 cN of orthodontic force were applied to the maxillary left first molars. Forty rats were distributed into control groups (CG1, CG3, CG7 and CG14) and experimental groups (n= 5), in which alveolar perforations were made using a spear-shaped guide bur (EG1, EG3, EG7, EG14). Euthanasia dates were set at 1, 3, 7 and 14 days, respectively, after tooth movement began. The amount of OTM was measured with a caliper, and osteoclasts present in the periodontal ligament of the mesial root of the moved tooth were counted by means of histological evaluation (tartrate-resistant acid phosphatase staining, TRAP). Results: Although there was no difference in the amount of OTM within subgroups of corresponding experimental periods (p> 0.05), when EG14 and CG14 were compared, a larger number of osteoclasts was counted in the experimental group (p< 0.00). Conclusion: The authors concluded that flapless cortical alveolar perforations led to more intense osteoclastic activity on the fourteenth day; nevertheless, no evidence of accelerated OTM could be noted.

<p><strong><em>Background:</em></strong><em> Orthodontic tooth movement is a </em><em>interaction prosess</em><em> of resorption and deposition of bone remodeling. Orthodontic tooth movement by mechanical strength causes changes in alveolar bone. Osteocyte is an essential cell to respond bone remodelling. Hyperbaric Oxygen Therapy affects production of osteocyte because it can release Reactive Oxygen Species (ROS) and Nitrid Oxide (NO).  <strong>Purpose: </strong>To determine the difference number  of osteocyte in pressure and tension area during tooth movement by adjuvant of Hyperbaric Oxygen 2,4 ATA during 7 days starting on day 8 to day 14. <strong>Materials and Methods</strong>: This research used Completery Randomized Control Group Post Test Only Design. 36 cavia cobaya (male)  were divided into 3 groups randomly : the negative control groups, positive control group, and treatment group. Preparat staining used Hematoxylin Eosin (HE) and calculated on microscop 1000x with 20 field of view. Data analyses used one way ANOVA and LSD test then compared each area by using paired T test. <strong>Result:</strong> The data showed that the treatment group (P=10,67) tension area has the highest number of osteocyte than  negative control group (K-=3,67), positive control (K+=7,42). In the pressure area showed that negative control group (K-=5,00) has the highest  than positive control group (K+=3,83) and treatment (P=3,25). <strong>Conclusion: </strong>Therapy HBO 2,4 ATA 7 days starting on day 8 to day 14 is could increase osteocyte in the tissue to stimulate process of bone remodelling.</em></p><pre><strong> </strong></pre><p><strong><em>Keywords:</em></strong><em> Hyperbaric Oxygen, Tooth movement, Bone remodeling, </em><em>Osteocyte</em><em></em></p><p><em> </em></p><p><strong><em>Correspondence:</em></strong><em> </em><em>Arya Brahmanta</em><em>, Department of Orthodonty, Faculty of Dentistry, Hang Tuah University, Arif Rahman Hakim 150, Surabaya, Phone 031-5945864, Email:</em><em> </em><a href="mailto:[email protected]"><em>arya.brahmanta</em><em>@</em><em>hangtuah.ac.id</em></a></p>

Introduction: The objective of this systematic review is to assess the effect of vibrational force on biomarkers for orthodontic tooth movement. Methods: An electronic search was conducted for relevant studies (up to December 31, 2020) on the following databases: Pubmed, Google scholar, Web of Science, Cochrane Library, Wiley Library, and ProQuest Dissertation Abstracts and Thesis database. Hand searching of selected orthodontic journals was also undertaken. The selected studies were assessed for the risk of bias in Cochrane collaboration risk of bias tool. The “traffic plot” and “weighted plot” risk of bias distribution are designed in the RoB 2 tool. The 2 authors extracted the data and analyzed it. Results: Six studies fulfilled the inclusion criteria. The risks of biases were high for 4, low and some concern for other 2 studies. The biomarkers, medium, device, frequency and duration of device, as well as other data were extracted. The outcomes of the studies were found to be heterogenous. Conclusion: One study showed highly statistically significant levels of IL-1 beta with <.001. Rate of tooth movement was correlated with levels of released biomarkers under the influence of vibrational force in 3 studies, but it was found to be significant only in 1 study. It was further observed that vibration does not have any significant reduction in pain and discomfort.
