Active clinical trials for "Root Resorption"

The duration of orthodontic treatment is one of the exacerbation causes of orthodontic pain. Several methods have been suggested to reduce the duration of orthodontic treatment classified to surgical and non-surgical methods. Researchers used minimally invasive surgical methods like corticision, piezocision, micro-osteoperforation, and piezopuncture indicated that most of these methods can accelerate dental movement by 20 - 40%. The effect of corticision as a minimally invasive procedure on root resorption and dehiscence formation during orthodontic tooth movement has not been studied yet. Applying corticision on the lower anterior teeth using a surgical blade and a hammer may accelerate tooth alignment during orthodontic treatment. This study consists of two groups, patients will be randomly assigned to one of these two groups.

This study aims to investigate the effectiveness of low-level laser in reducing the resorption of the roots of the upper incisors. Participants will be recruited from patients who will attend the Department of Orthodontics and Dentofacial Orthopaedics at Damascus University. The study sample will consist of 30 patients with a deep bite who will be randomly distributed equally into two groups, 15 patients in each group, average age: 22.37±3.38 years. Mini-implants will apply between the roots of the maxillary central and lateral incisor at both sides with a loading force of 40 g on each end by using a nickel-titanium spring extending from the head of the mini-implants to a wire welded to it with two hooks. A low-level laser (Ga-Al-As) will be used with 808 nm wavelength in continuous mode, 250 milli-Watt power output, 4 Joules/point energy density, 16 s per point in the experimental group. It will be applied on the day of intrusion, then on days 3,7, and 14 of the first month, and then every 15 days starting from the second month until the end of the intrusion. In addition to adjusting the force gauge every 4 weeks until the end of the intrusion stage and reaching normal coverage will be activated every 4 weeks in both groups until normal overbite was reached.

Currently Endodontics looks forward for regeneration rather than repair. Regenerative endodontic therapy was limited to pulp revascularization of necrotic pulp in immature teeth , followed by mature teeth. Recently pulp revascularization technique by induction of blood clot was applied in the treatment of inflammatory root resorption. So far, no clinical study for management of teeth with inflammatory internal root resorption by using injectable PRF revascularization has been described in the literature. Thus, this is the first clinical attempt to manage inflammatory root resorption in necrotic incisor teeth using injectable PRF regenerative approach.

Aim: The aim of the study was to evaluate and compare the extent of root resorption in the maxillary and mandibular anterior teeth during orthodontic treatment with the use of different types of brackets. Materials and methods: The study consisted of 21 patients (11 males and 10 females) within the age group of 16-25 years, having bimaxillary protrusion. They were divided into three groups. In Group 1- Conventional brackets, Group 2- Self-ligation brackets:Smart Clip (Passive), and in Group 3 Self-ligation brackets: Empower (Active) were bonded. Computed Tomography scans and Orthopantomograms were taken before start of treatment and after six months of retraction. Root resorption is computed as the difference between the pre treatment total tooth length and the post treatment total tooth length.

External root resorption is a common unfavourable sequel of orthodontic treatment. Although diagnosis of root resorption is usually done by radiographs; they are technique sensitive. Dentine phosphoprotein, a non-collagenous protein, is suggested to be released into the gingival crevicular fluid during active root resorption, serving as a good diagnostic tool. Also, the manner of force application is a modifiable factor suggested to affect root resorption.

The aim of this study was to investigate the effect of mechanical vibration on root resorption with or without the application of orthodontic force. Twenty patients who required maxillary premolar extractions as part of their orthodontic treatment were randomly separated into two groups of 10: no-force group and force group. Using a split-mouth procedure, each patient's maxillary first premolar teeth were randomly assigned as either vibration or control side in both groups. Buccally directed vibration of 113 Hz, using an Oral-B HummingBird device with a modified tip, was applied to the maxillary first premolar for 10 mins/day during 12 weeks. After the force application period, the maxillary first premolars were extracted and scanned with micro-computed tomography. Fiji(ImageJ) which made slice-by-slice quantitative volumetric measurements was used for resorption crater calculation. Total crater volumes was compared with Wilcoxon and Mann-Whitney U tests.

The purpose of the study is evaluate the histological changes of the dentinal-pulp complex and root resorption in maxillary premolars with intrusive orthodontic movement under a low power laser effects.

The intended study is designed as a prospective randomized controlled trial (RCT), comparing and contrasting the effect of mini-screw implant anchorage-assisted versus regular maximum anchorage by retracting the maxillary incisors.

The majority of previous studies for early detection of Orthodontically Induced Inflammatory Root Resorption (OIIRR) were conducted to assess individual biomarkers which are representative of single biological pathway. To our Knowledge, no studies have been employed Gingival crevicular fluid (GCF) proteomic analysis to identify potential biomarkers for OIIRR. Therefore; the aim of this study is to use the advantage of testing a package of biomarkers via doing proteomic analysis of GCF which could help in making a more precise personalize diagnosis and treatments, thereby providing orthodontists additional information that cannot be deduced from clinical parameters.

The aim of the study is to perform a clinical and radiographic evaluation of 70% Ethanol Alcohol versus Normal Saline as root canal irrigating solutions in partial pulpectomy of primary molars with Metapex.
