Comprehensive comparison of canine retraction using NiTi closed coil springs vs elastomeric chains

Barsoum, Haya A; ElSayed, Hend S; El Sharaby, Fouad A; Palomo, Juan Martin; Mostafa, Yehya A
OBJECTIVES:To compare canine retraction using NiTi closed coil springs vs elastomeric chains comprehensively in a split-mouth randomized controlled trial. MATERIALS AND METHODS:The canines in 64 quadrants were randomly retracted into the first premolar extraction spaces using NiTi closed coil springs or elastomeric chains, in the maxilla and mandible. The retraction force was 150 g. Cone beam computed tomography scans and study models were obtained before the start of canine retraction and 6 months later. The rate and total amount of canine retraction, canine rotation, tipping, and root resorption were evaluated. A visual analogue scale was used to evaluate patients' pain experience. RESULTS:The two methods were statistically similar for dental changes, rate of canine retraction, and root resorption. However, patients reported significantly more days of pain with the elastomeric chain compared to the NiTi closed coil springs. CONCLUSIONS:Within the constraints of the current study, using either NiTi closed coil springs or elastomeric chains as force delivery systems for canine retraction results in no significant difference in the rate of canine retraction, tipping, rotation, or root resorption. Pain experience during retraction using elastomeric chains is more significant yet needs further investigation.

Fixed orthodontic treatment has an insignificant effect on clinical attachment level

ElSayed, Hend; Elkhadem, Ahmed
Data sources Medline, Embase, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Scopus, Web of Knowledge, Virtual Health Library, Google Scholar and ISRCTN registry databases.Study selection Randomised controlled trials (RCTs) and prospective or retrospective non-randomised clinical trials on periodontal healthy human patients receiving comprehensive fixed appliance treatment were considered.Data extraction and synthesis Two reviewers independently extracted data and assessed risk of bias using either the Cochrane tool for RCTs or the ROBINS-I (Risk Of Bias In Non-randomised Studies - of Interventions) tool for non-randomised studies. A Paule-Mandel random-effects meta-analyses was conducted for clinical attachment loss. Results Nine prospective non-randomised trials involving a total of 335 periodontally healthy patients were included. The patients' average age was 22.6 years (range 11.4 - 42.1 years). Seven of the nine studies were assessed as being at moderate risk of bias. Orthodontic treatment was associated with a mean clinical attachment loss of 0.11 mm (95 %CI: 0.12 mm gain to 0.34 mm loss; P = 0.338, I2 = 99.6%), which was neither statistically nor clinically significant.Conclusions The findings suggest that orthodontic treatment might have little or no clinically relevant detrimental effect on the clinical attachment levels of patients.

Comparison of transverse changes during maxillary expansion with 4-point bone-borne and tooth-borne maxillary expanders

Mosleh, Mennatallah Ihab; Kaddah, Mohamed Amgad; Abd ElSayed, Fatma Abdou; ElSayed, Hend Salah
INTRODUCTION/BACKGROUND:The purposes of this study were to evaluate and compare the dentoskeletal changes concurrent with 4-point bone-borne and tooth-borne rapid maxillary expanders in growing children. METHODS:The study was conducted with 20 growing girls (ages, 12 ± 0.6 years) with posterior crossbite. They were divided into 2 equal groups; patients in one group were treated with a tooth-borne maxillary hyrax expander (TBME), and those in the other group received a bone-borne maxillary hyrax expander (BBME) anchored directly to the palatal bone. Changes were assessed using cone-beam computed tomography. Images were taken before and immediately after expansion. RESULTS:Superimpositions of the 3-dimensional palatal images showed significant increases in skeletal widths at the canine, first premolar, and first molar areas in both groups. The TBME group had greater nasal width expansion. Regarding the transverse dentolinear measurements, significant increases were seen in both groups, whereas the TBME group showed a greater increase than the BBME group. Significant increases in the dentoangular measurements were seen in the TBME group only and were significantly greater than in the BBME group at the first premolars. CONCLUSIONS:There were significant increases in facial and maxillary widths for the BBME group and in nasal width for the TBME group. Both expanders produced basal bone expansion at the level of the hard palate. The TBMEs produced more dental expansion, buccal rolling, and a greater increase in nasal width than did the BBMEs.

Accelerated tooth movement: Do we need a new systematic review? [Review]

Rozen, Daniel; Khoo, Edmund; El Sayed, Hend; Niederman, Richard; McGowan, Richard; Alikhani, Mani; Teixeira, Cristina C
Current systematic reviews are important for health care providers in supporting their evidence-based practice decisions. Equally important is the ability to determine when a new systematic review is needed in view of the rapid publication output. The current best evidence from a 2013 systematic review suggests that certain treatments may accelerate orthodontic tooth movement. Our aim was to determine if an updated systematic review is needed on this topic by applying the modified Ottawa method. A systematic search of Pubmed, Embase, CENTRAL, and Web of Science databases, identical to the previous systematic review, was executed. Two authors performed screening for inclusion/exclusion of studies and selected full-text articles were reviewed. Qualitative and quantitative criteria were applied to assess studies describing the following types of interventions to accelerate tooth movement: electrical, photobiomodulation, micro-osteoperforations, vibration, corticotomy, and low-level laser therapy. The Ottawa method showed that studies produced since 2011 have (1) potentially invalidating evidence and description of new methods and (2) combined new data that would enhance the precision of the existing evidence on low-level laser therapy. These collectively indicate the need for a new systematic review on adjunct procedures to accelerate orthodontic tooth movement, which may offer new evidence and techniques not previously mentioned.

Quality of life and sexual activity during treatment of Bartholin's cyst or abscess with a Word catheter

Reif, Philipp; Elsayed, Hend; Ulrich, Daniela; Bjelic-Radisic, Vesna; Häusler, Martin; Greimel, Elfriede; Tamussino, Karl
OBJECTIVES/OBJECTIVE:Cysts and abscesses of the Bartholin glands are a common occurrence in gynecologic or general practice. Little is known about restrictions in patient's daily life and sexual activity during treatment of Bartholin's cysts in general and especially with the Word catheter. This study is to assess the Quality of Life and Sexual Activity during treatment of Bartholin cyst's and abscesses with the Word-catheter. STUDY DESIGN/METHODS:Between March 2013 and May 2014 30 women were included in the study. Pain before treatment and during catheter insertion and removal was assed using a standardized VAS scale. Health-related quality of life was assessed with the Short-Form-12-Health-Survey. Fallowfield's Sexual Activity Questionnaire was administered to investigate sexual limitations. During treatment patient self-reported to a pain-diary (VAS 0-10). RESULTS:Pain levels decreased from a 3 [0-10] on day 1 to 0 [0-6] on day 6 with the median staying at 0 for the remaining treatment period. Discomfort and pain during sexual activity decreased significantly from initial presentation to end of treatment. The mental component summary score of the SF 12 increased significantly from 46.94±10.23 before treatment to 50.58±7.16 after treatment (p=0.016); the physical component summary score did not change significantly. CONCLUSIONS:The Word catheter is well tolerated for the treatment of Bartholin's cysts and abscesses with few and no serious side effects and little impingement of sexual health. A more relevant informed consent ahead of treatment, specifically with regard to pain in the first few days after catheter placement, might further increase acceptance of the catheter and adjust patient expectations.
