Honey can be used as an alternative to traditional remedies for the prevention of dental caries and gingivitis following orthodontic treatment.

Objectives: to evaluate PowerScope appliance assisted with Low-Level Laser Therapy on mandibular changes in the treatment of skeletal class 2 malocclusions. Subjects and methods: The current study was conducted on 24 orthodontic female patients with an age range from 14-to 16-year-old who were collected from the outpatient clinic at

Objective: To evaluate and compare the efficacy of Mandibular protraction appliance IV (MPA-IV) and PowerScope (PS) in the treatment of skeletal Class II malocclusion patients. Subjects and methods: A total of 16 circumpubertal class II patients (ANB°>4°) with mandibular deficiency were randomly divided equally into two groups; group 1: treated by MPA-IV, their mean age was 14.98 ± 1.33 years, group 2: treated by PS appliance (American Orthodontics, Sheboygan, Wis), their mean age was 14.67 ± 1.37 years. In both groups, fixed functional appliances were installed for six months. Treatment outcomes were assessed by cephalograms taken immediately pre-and post-functional appliances therapy. Results: Intergroup comparisons of the mean treatment changes revealed significant improvements (P ≤ .05) in SNB°, SN-Pog°, Ar-Go-Me°, Co-Gn mm, B-Sv mm, Pog-Sv mm, S-Go mm, and lower lip advancement (Li-Sv mm and Pog'-Sv mm) in MPA-IV group. While in the PS group, there were significant greater decrease of SNA° and upper incisors retraction (P ≤ .05). Conclusion: Both appliances could be used efficiently in the treatment of class II malocclusion. MPA-IV produces superior mandibular advancement and lower lip projection, while the effects of PS are mainly dentoalveolar changes.

OBJECTIVE:To evaluate the maxillary canine retraction rate and anchorage loss with active and passive self-ligating brackets (SLBs).MATERIALS AND METHODS:The study was conducted on 10 patients whose age ranged from 14–20 years. The patients had minimal to no crowding with a dental protrusion of maxillary incisor that required the extraction of maxillary first premolars and retraction of canines. The maxillary canines had to be in a good alignment and level before treatment to ensure that canine retraction had started from the same point bilaterally. A cone beam computed tomography (CBCT) had been taken for each patient's maxilla before treatment initiation and after complete canine retraction. Using nickel titanium, close-coil spring canine retraction on both sides and the rate of canine movement was measured.RESULTS:The patients were checked every 2 weeks to measure the retraction rate and ensure that a constant force (150 g) was being delivered to both canines. The pre- and post-canine retractions CBCT were superimposed to evaluate the pattern and rate of canine movement and anchorage loss. The result of this study showed no statistically significant difference between the two groups.CONCLUSION:The type of SLB, either active or passive, does not affect the rate or type of canine movement during its retraction in the orthodontic extraction cases, and the anchorage loss of the upper molars was nearly the same in both type.

Objective: to evaluate the dentoskeletal effects of maxillary skeletal expander (MSE) in adult orthodontic patients, using Cone Beam Computed Tomography (CBCT). Patients and Methods: The current study was conducted on 14 adult orthodontic patients (4 males and 10 females), with their age ranged from 18 to 21 years, treated with a special type mini-implant assisted rapid palatal expander called, MSE (Maxillary Skeletal Expander) to correct transverse maxillary deficiency. The CBCT images were performed before the start of the orthodontic expansion (T1) and 3 months after the last activation (T2). Paired t-test, and descriptive statistics were used to evaluate the amount and the pattern of the mid-palatal suture opening, the total amount of maxillary expansion and the change in the inter-molar distance and molar inclination. Results: Four patients were dropped-out for different reasons, so, the statistical analysis was performed only on 10 patients (3 males, 7 females). The midpalatal suture split by 2.96mm and 2.64mm at the anterior nasal spine (ANS) and the posterior nasal spine (PNS) respectively, with a ratio of 89% between the PNS and the ANS. The maxillary width showed increase by 2.99 mm between the right and left zygomaticomaxillary sutures. The inter-molar distance and the molar inclination showed increase by 5.3 mm and 5.4 o respectively. Conclusions: MSE is an efficient appliance for producing rapid palatal expansion and mid-palatal suture opening in adult orthodontic patients and can be used as an alternative to the surgically assisted rapid palatal expansion. MSE expansion affects the involved molars, causing increased inter-molar distance with limited buccal tipping.
