Introduction: In Majority of patients seeking orthodontic treatment, teeth must be extracted in order to obtain proper esthetics, occlusion, and stability as well as extraction of teeth is often a need to close residual space, after the initial decrowding and aligning. Pre adjusted fixed orthodontic appliances commonly utilize sliding mechanics for space closure with different types of force delivery systems. A variety of materials have been used as force delivery systems to close spaces between teeth as in the case of canine retraction after the extraction of premolars. Among all sliding or frictionless methods of canine retraction, super-elastic nickel titanium coil spring has a particular property in producing light continuous force at a long range of action, compared with previously available materials. Nickel-titanium closed coil spring, with a continuous action, might have some advantages in fixed appliance space closure mechanics. Materials and Methods: Over the period of one year from May 2015 to April 2016, this clinical trial was carried out and A total number of 20 patients (40 quadrants), who required canine retraction into first premolar extraction sites as part of their orthodontic treatment in the Department of Orthodontics of BSMMU selected as study population. The quadrants were affixed by nickel titanium closed coil springs (medium force, Ni-Ti extension spring, Ormco) with 200gm force measured by Correx Tension Gauge. Space closure was measured by means of direct measurement from the mesial surface of mesial wing of the 2nd premolar bracket and the distal surface of distal wing of the canine bracket with digital Vernier Calipers. Results: Mean space closer rate in mandibular canine retraction was 1.07 ± 0.12 mm/month by nickel-titanium (Ni-Ti) closed coil spring method with p value<0.001. Conclusion: This study revealed that space closer rate in mandibular canine retraction by nickel-titanium (Ni-Ti) closed coil spring is 1.07 ± 0.12 mm/month. Medicine Today 2021 Vol.33(2): 90-93

Objectives: This study was aimed to assess salivary sodium and potassium concentrations in patients with fixed orthodontic appliances. Methods: In this case-control study, saliva samples (5 cc) were collected from 13 patients with fixed orthodontic appliances before, and 1 week, 1 month and 3 months after the beginning of the orthodontic treatment using the spitting method. Saliva samples were also collected from 10 healthy individuals as controls. The saliva samples were centrifuged at 3000 rpm for 10 minutes and the salivary sodium and potassium concentrations were measured by spectrophotometry. Data were analyzed using independent and paired t-tests. P-value < 0.05 was considered as significant. Results: The salivary sodium and potassium concentrations were almost the same in both groups at baseline (P > 0.05). A significant reduction in sodium and an increase in potassium levels were noted in the case group at 1 week compared with baseline (P < 0.001). At 1 week, the potassium concentration was significantly higher and the sodium concentration was significantly lower in the case group (P < 0.01). The salivary sodium significantly increased while the salivary potassium significantly decreased at 1 month compared with 1 week (P < 0.001). The differences with the control group were also significant (P < 0.05). No significant differences were noted between the two groups at 3 months (P > 0.05). Conclusions: Time has a significant effect on the release profile of sodium and potassium ions from orthodontic appliances. The salivary sodium and potassium concentrations returned to their normal pretreatment values within 3 months after the start of fixed orthodontic treatment.

Introduction. When planning orthodontic treatment, it is sometimes necessary to apply the extraction of individual teeth, in order to achieve proper occlusion and an acceptable aesthetic appearance. Clinicians give the greatest advantage to elastic chains as a method for post-extraction space closure during treatment with fixed orthodontic appliances. When closing post-extraction spaces, it is necessary to measure them in order to adjust the treatment plan. One of the most acceptable methods is photogrammetry. The aim of this study was to analyze, using a photogrammetric method, the efficacy of post-extraction space closure with elastic chains during orthodontic treatment with fixed orthodontic appliances. Material and Methods. The total sample in study consisted of 38 post-extraction spaces in 19 patients who were indicated for first premolars extraction and use of fixed orthodontic appliances in order to achieve treatment goal. Elastic chains were used to close post-extraction spaces. Post-extraction sites were monitored for 6 months with follow-up examinations every 4 weeks. Mechanisms were activated at controlled examinations, and measurements of the width of post-extraction spaces were performed by photogrammetry and digital caliper. Results. The results showed that average reduction of post-extraction space width was 1.00 mm per month by photogrammetric measurement, while the average values of measurements with a digital caliper were 1.02 mm. The average values were measured in six time intervals and a statistically significant change in average intervals of post-extraction spaces during 6 months was determined. Conclusion. The elastic chain has proven to be a very effective mechanism for closing post-extraction space, and photogrammetry as a simple and precise method for monitoring results of treatment. Since the difference in relation to measurements with a digital caliper is minimal, photogrammetry can be routinely applied in everyday practice.

Introduction: The evaluation of changes in orthodontic practice over the years, is essential for defining treatment efficacy. Accordingly, shedding light on the profile of orthodontic practice in Saudi Arabia is crucial. Aim: To investigate current trends in orthodontic practice in Saudi Arabia and the factors affecting choices regarding materials and techniques among orthodontists. Materials and Methods: This cross-sectional study was conducted from July 2019 to December 2019 at the College of Dentistry, King Saud University, Riyadh, Saudi Arabia. An electronic survey of 29 objective questions was sent to 1,500 orthodontic members of the Saudi Orthodontic Society. The survey collected demographic data, diagnostic records and information on the fixed orthodontic appliances used by the respondents. Frequency and percentages were calculated for all variables. Chi-square test was used to determine the effects of factors, including years of experience and place of work, on the choice of diagnosis protocol and fixed appliance material, with the significance set at p-value ≤0.05. Results: Two hundred and nine respondents completed the survey. The respondents reported a highly significant use of computers for digitising cephalometric analysis, with the traditional method of obtaining study models reported as highly significant (p<0.001). Orthodontists routinely used the MBT preadjusted bracket system (52.6%) and performed direct bonding of the bracket (91.4%). Bonding of the first molars was preferred by 36.4% of the clinicians. Glass ionomer cement was the most frequently used band cement (55.5%), and the most popular archwire material was nickel–titanium shape memory. Clinicians with less than five years of experience used significantly more postcephalometric radiographs (p=0.006) and postorthodontic treatment models (p=0.028). Senior orthodontists (10-15 years of experience) had a higher use of indirect bonding techniques (p=0.05). Conclusion: This study provides information on the relevant aspects of orthodontists in Saudi Arabia in terms of their individuality, training and techniques used. The findings can be used as a reference for future national surveys to evaluate changes in orthodontic practice in Saudi Arabia.

Introduction: Enamel decalcification in the form of white spot lesion is a common complication seen in patients with fixed orthodontic appliances. Objective: To determine the prevalence of white spot lesion among Nepalese fixed orthodontic patients, to compare the occurrence of WSL among the patients with lesser and greater duration of treatment, and to compare between the gender groups. Materials & Method: A cross-sectional study was done to compare the prevalence of WSL between 300 orthodontic patients and 100 non-orthodontic subjects. Further comparison was done between the mean treatment duration between orthodontic subjects of 6-18 months and >18 months, and between male and female samples. Subjects were visually examined on second premolar to second premolar in both maxillary and mandibular arches using Gorelick’s WSL index. Descriptive statistics were calculated and independent t-test was used to compare the difference between the groups. The p-value <0.05 was considered significant. Result: The prevalence of WSL in Nepalese orthodontic patients was 54.3%; among them prevalence was 40% in lesser treatment duration group and 68.7% in greater treatment duration group. The study found significant difference between untreated nonorthodontic group and orthodontically treated group with respect to the number of teeth affected with WSL. Also, there was significant difference between the categories of orthodontic treatment duration. There was no significant difference between male and female samples. Conclusion: Fixed orthodontic treatment increase the risk of white spot lesion. Duration of orthodontic treatment also showed significant increase in the occurrence of WSL.

Summary Introduction In everyday clinical practice, we often encounter a lack of space for placing all the teeth present into dental arch; therefore it is often recommended to extract teeth within orthodontic treatment. In clinical practice, the most commonly used methods of closing space after are elastic chains and NiTi closed spiral springs. The aim of this paper was to compare postextraction space closure speed using two different sliding mechanisms, NiTi closed coil springs and elastic chains within treatment with fixed orthodontic appliances. Material and Method The total sample in this study consisted of 46 postexstraction spaces in 23 patients indicated for the extraction of first premolars using treatment with fixed orthodontic appliances. Two sliding mechanisms, NiTi closed coil spring and elastic chains were applied to postextraction space closure. Postextraction spaces were monitored for 4 months with appointments every 4 weeks. During appointments mechanisms were activated and digital caliper was used to measure the width of the postextraction space. Results The results showed that NiTi closed coil springs method achieved greater reduction in postexstraction space (3.94 mm) while with elastic chain method the closure of 3.10 mm was achieved. The total difference between these two methods in the observed period was 0.84mm and no statistically significant difference was found (p> 0.05). The lowest value for NiTi closed springs was 2.19 mm, while for the elastic chain it was 1.29 mm. The best postextraction space closure was 5.70 mm and it was completed using NiTi closed springs while for elastic chain the best value was 4.80 mm. Conclusion: NiTi closed coil springs lead to faster closure of postextraction spaces in relation to elastic chain. Since this difference is minimal, in practice, both methods can be used equally.
