Impact of orthodontic treatment complexity on oral health-related quality of life in Turkish patients: A prospective clinical study

Objective: The study aimed to evaluate the relationship between orthodontic treatment complexity and oral health-related quality of life (OHRQoL) and to assess the impact of malocclusion and orthodontic treatment on OHRQoL in orthodontic patients with regard to gender and age. Methods: This prospective clinical study included 102 patients aged 13-35 years who were referred to the orthodontic department. The impact of orthodontic treatment complexity was assessed using the Index of Complexity, Outcome and Need (ICON). The Turkish version of the Oral Health Impact Profile (OHIP-14) was used to examine the subjects for OHRQoL before and after treatment. The before and after treatment data (T1 and T2, respectively) were tested using a paired t-test, and one-way analysis of variance (ANOVA) with the Bonferroni test was used to assess the differences in OHIP-14 across groups, as defined by the ICON. The cross-sectional comparisons between genders and age groups before and after treatment were tested using the Student's t-test. The level of significance was set to a p value of 0.05. Results: Patients with moderate treatment complexity reported a significantly negative impact on the psychological disability domain compared to the difficult treatment complexity. OHRQoL improved after treatment. Females showed statistically significant and highest scores on the physical pain domain compared to males. Adults showed a statistically significant negative impact on the psychological domains before treatment as well as a statistically significant positive impact on the psychological disability domain after treatment compared to adolescents (p<0.05). Conclusion: Orthodontic treatment improves OHRQoL, and orthodontic treatment complexity does not seem to have an impact on OHRQoL

Evaluation of the relationships between chronological age, skeletal maturation, dental maturation, and sagittal jaw relationships

Objective: The present study aimed to determine whether there is a correlation between chronological age, skeletal maturation, dental maturation, and ANB angle.Methods: Lateral cephalometric, panoramic, and hand-wrist radiographs of 200 orthodontic patients were used (100 males and 100 females; mean age 13.00 and 13.70 years, respectively). Skeletal maturation was determined by two different methods: cervical vertebral maturation (CVM) and the hand-wrist radiography method of Grave-Brown. Dental maturation was defined by the Demirjian Index using the mandibular canine, premolars, and second molar on the left side. The ANB angle was measured on lateral cephalometric head films. The data were analyzed by Spearman's rank correlation analysis.Results: Correlation coefficients of the male and female subjects were 0.825 and 0.802 between chronological age and hand-wrist evaluation; 0.744 and 0.778 between chronological age and CVM evaluation; 0.677 and 0.443 between chronological age and mandibular canine development; 0.722 and 0.458 between chronological age and mandibular first premolar development; 0.730 and 0.517 between chronological age and mandibular second premolar development; 0.701 and 0.531 between chronological age and mandibular second molar development; and -0.183 and -0.045 between chronological age and ANB, respectively. All the correlations mentioned above were statistically significant (p&lt;0.001), except for the last one.Conclusions: High correlations were found between the chronological age, hand-wrist, and cervical vertebral maturation evaluations. Chronological age was also correlated with dental maturation, particularly in mandibular second molars. There was no correlation between ANB and the other parameters

Clinical comparisons of different fixed orthodontic retainers

Objective: The aim of this prospective clinical study was to compare the clinical outcomes of three different fixed lingual retainers, in terms of effects on periodontal health and success rate. Methods: Forty five patients aged 13 to 25 years were randomly assigned into three groups, using bonded upper and lower lingual retainers. The study groups were as follows: Group 1-BondA-Braid®, Group 2-everStick® ORTHO, Group 3-Super-Splint. The follow-up appointments were performed two weeks (Baseline=T0), one month (T1), three months (T2), and six months (T3) after the application of retainers. Plaque Index (PI), Gingival Index (GI), Probing Depth (PD), Bleeding in Probing (BOP) and Retainer Failure were assessed at each appointment. Results: The everStick Ortho group showed significantly lower PI values on the upper-lower lingual side after three (p=0.008) and six (p=0.001) months. The everStick Ortho group had significantly lower upper lingual (GI) levels after six months, and lower lingual side levels after one month. The Super-Splint group showed significantly lower PD values on the upper lingual side after six months. The everStick Ortho group presented significantly lower BOP levels after six months on the upper lingual side. No significant differences between the groups (p>0.05) in terms of retainer failure were found. Conclusions: The everStick Ortho group presented better results in terms of periodontal health. The failure rates of the retainers were similar

Pain and chewing sensitivity during fixed orthodontic treatment in extraction and non-extraction patients

WOS: 000408113700004PubMed ID: 28955592Purpose: The aim of this study was to evaluate the differences in pain perception and chewing sensitivity between extraction and non-extraction patients. Subjects and Methods: Thirty orthodontic patients (11 males, 19 females) were included in this study who were classified as extraction (n=15; 6 males, 9 females) and non-extraction patients (n=15; 7 males, 8 females). The mean age of patients were 15.10+/-1.83 years in non-extraction group and 15.44+/-0.75 years in extraction group. The patients were asked to complete the Visual Analogue Scale (VAS) questionnaire and they were asked to mark the presence or absence of sensitivity during 7 days after the first arch wire placement. Pain intensity comparison between groups was performed using the Mann-Whitney U test. The Friedman test was used to analyze within-group differences over time. Results: There were no significant differences in pain scores between the groups. Pain levels significantly decreased between day 1 and day 3 in both the groups. No differences were found in the chewing sensitivity between the non-extraction and extraction groups. Conclusion: No difference in the pain perception was observed between the extraction and non-extraction patients during the 7 days after arch wire placement

Effect of fluoride releasing bonding materials on shear bond strength of orthodontic brackets

Objective: The aim of the present study was to compare the shear bond strength (SBS) of three different fluoride-releasing bonding agents with a conventional adhesive system.Methods: Eighty-four extracted human premolar teeth were separated into four groups and embedded in acrylic molds consisting of 21 teeth in each group. Brackets were bonded with Transbond XT in group 1, Clearfil SE Protect Bond in group 2, LED Proseal in group 3, and Opalseal in group 4. After bracket bonding, the teeth were thermocycled 1000 times. SBS test was performed, and Adhesive Remnant Index (ARI) scores of the groups were assessed.Results: One-way analysis of variance test was used to compare the significant differences between the groups. Chi-square and Fisher's exact tests were used to evaluate ARI scores. The Opalseal group showed the highest bond strength, but there was no statistically significant difference between the groups in SBS values (p=0.067).The results of ARI scores were statistically significant.Conclusions: All bonding materials used in the study showed clinically sufficient bond strengths

Microimplants in lingual orthodontics

Ortodontik tedavi sırasında ankrajı arttırmak amacı ile geleneksel ağız içi, ağız dışı ankraj mekaniklerinin yanı sıra mikroimplantlar da kullanılmaktadır. Ortodontik tedavi sırasında dikkat edilmesi gereken en önemli konu ankraj kullanımıdır. Bu sayede mutlak ankrajı sağlamak ve hasta iş birliğini ortadan kaldırmak söz konusu olmaktadır. Estetik diş hekimliğinin önemli bir parçası olan lingual ortodonti tekniğinde de labial ortodontideki gibi ankraj gereksinimi için mikroimplantlar kullanılmaktadır. Lingual ortodontide aşılması gereken en önemli zorluklardan biri üst ön grup dişlerin ankraj ve tork kontrolüdür. Bu derlemenin amacı lingual ortodontide mikroimplant kullanımını incelemektir. Yapılan literatür taraması sonucu mikroimplantların lingual ortodontik tedavide etkin bir şekilde kullanıldığı tespit edilmiştir.During orthodontic treatment different traditional biomechanical techniques, such as extraoral or intraoral anchorage mechanics and also microimplants can be used to reinforce the anchorage. The most important issue in orthodontics is anchorage. Absolute anchorage can be achieved and the quality of the treatment result can be independent of the patient's cooperation by using microimplants. Lingual orthodontics is a main part of esthetic dentistry and microimplants can be used to reinforce the anchorage as done in labial orthodontic therapy. One of the difficulties of lingual orthodontics is the control of anchorage and torque of the anterior teeth. Previous reports suggested that microimplants are effectively used in lingual orthodontics

Rapid maxillary expansion outcomes according to midpalatal suture maturation levels

Background: This study aims to compare the relationship between skeletal and dental outcomes of rapid maxillary expansion (RME) treatment on cone beam computed tomography (CBCT) images between pre-pubertal peak (pre-peak) and post-pubertal peak (post-peak) patients. The null hypothesis was that there was no difference in the outcomes of RME treatment between the groups. Methods: Thirty-two patients who underwent RME treatment were classified according to midpalatal suture maturation levels and then divided into two groups as pre-peak and post-peak. Skeletal and dental measurements were performed on the CBCT images at T0 (pre-treatment stage) and at T1 (post-treatment stage). Paired sample t test was used to evaluate normally distributed data and P < 0.05 was taken as the significance level. Results: There were significant differences between T0 and T1 within the groups, but the changes between the pre-peak and post-peak patient groups were not statistically significant. Conclusion: Non-significant changes were found between the two groups, and the null hypothesis was excepted

Besteht ein zusammenhang zwischen impaktion des oberen eckzahns und asymmetrie der augen

Introduction: Impacted maxillary canines may be in close proximity with related structures, such as the nasal cavity, orbital cavity, and maxillary sinus. The aim of this study was to evaluate the effects of unilateral maxillary canine impaction on ocular asymmetry. The null hypotheses were as follows: (1) there is no difference in the ocular location between the subjects with impacted canines and the control group; (2) there is no difference in the ocular location between the two sides of subjects with impacted canine. Methods: A total of 50 subjects with unilateral palatally impacted maxillary canines were selected as the study group, and 49 subjects without any impacted teeth were selected as controls. Ocular asymmetry was evaluated on standardized frontal photographs of the subjects in both groups, and the results were statistically compared. Results: Unilateral impaction of maxillary canines did not have a statistically significant effect on the vertical ocular location, nor did maxillary canine impaction affect the horizontal ocular location on either side of the face within the impacted canine group. There was a statistically significant difference in the horizontal ocular location between the impacted canine group and the control group. Gender differences did not have an effect on the ocular location in either of the study groups. Conclusions: Both hypotheses were accepted. A relationship between the impacted maxillary canine and ocular asymmetry could not be demonstrated.Einführung Impaktierte Oberkiefereckzähne können sich in unmittelbarer Nähe zu benachbarten Strukturen befinden, etwa zur Nasenhöhle, zur Augenhöhle und zum Sinus maxillaris. Ziel dieser Studie war es, die Auswirkungen einer einseitigen Impaktion des oberen Eckzahnes auf die Symmetrie der Augen zu untersuchen. Die Nullhypothesen waren wie folgt: (1) Es gibt keinen Unterschied in der okulären Position zwischen den Probanden mit impaktierten Eckzähnen und der Kontrollgruppe; (2) es gibt keinen Unterschied in der okulären Position zwischen den beiden Seiten der Probanden mit impaktierten Eckzähnen. Methoden Insgesamt 50 Probanden mit einseitig palatinal impaktierten Oberkiefereckzähnen bildeten die Studiengruppe, und 49 Probanden ohne impaktierte Zähne wurden als Kontrollen ausgewählt. Die okuläre Asymmetrie wurde an standardisierten Frontalfotos der Probanden beider Gruppen ausgewertet, und die Ergebnisse wurden statistisch evaluiert. Ergebnisse Die Impaktion eines oberen Eckzahnes hatte keinen statistisch signifikanten Einfluss auf die vertikale Augenposition. Sie hatte auch keinen Einfluss auf die horizontale okuläre Position auf beiden Seiten des Gesichts innerhalb der Gruppe mit impaktiertem Eckzahn. Es gab einen statistisch signifikanten Unterschied in der horizontalen okulären Position zwischen der Gruppe mit Impaktion und der Kontrollgruppe. Geschlechtsbezogene Unterschiede zeigten in beiden Gruppen keinen Einfluss auf die Augenposition. Schlussfolgerungen Beide Hypothesen wurden akzeptiert. Ein Zusammenhang zwischen einseitig impaktierten Oberkiefereckzähnen und Augenasymmetrien konnte nicht nachgewiesen werde

Assessment of reliability of YouTube videos on orthodontics

Objective: In addition to being an entertainment channel, YouTube is also one of the most popular visual information sources today. People search YouTube to consult also on orthodontics, as well as on many other topics. The objective of the present study was to analyze the quality and reliability of information of the videos on YouTube about orthodontics. Methods: YouTube was searched systematically by two researchers on orthodontics by using the keywords "Orthodontics,""Orthodontist" and "Orthodontic Treatment!Videos on the first three pages (60 videos) for each keyword were assessed. Researchers evaluated the reliability of the videos by using the Reliability Score (adapted from DISCERN) and the quality of the videos by using the Global Quality Score (GQS). Results: The mean GQS results were 2.6 +/- 1.3 for videos in the"Orthodontist" group, 3.2 +/- 13 for videos in the"Orthodontics" group, and 2.3 +/- 1.2 for videos in the "Orthodontic Treatment" group on a 5-point scale. The Reliability Score results were 2, 2, and 1.5 for videos in the "Orthodontist,""Orthodontics," and "Orthodontic Treatment" groups, respectively, on a 5-point scale. The Intraclass Correlation Coefficient results presented a positive relationship between the researchers. Conclusion: Owing to the lack of peer-review process and pre-upload scientific evaluation process, videos on YouTube can lead the public to misinformation

Sabit ortodontik tedavinin ilk üç ayında kilo kaybının değerlendirilmesi

Background: To asses weight changes in patients in the first three months of fixed orthodontic treatment. Materials and Methods: 53 patients (12 males, 41 females) in test group who needed fixed orthodontic treatment were selected. 50 subjects (14 males and 36 females) with similar conditions were selected as control. The mean age was for treatment group was 17.44±0.75 and was 17.67±0.85 for control group. Weight values of patients recorded immediately before bonding of brackets at beginning of treatment, 1 week after bonding and in orderly 1, 2 and 3 months after bonding. The same values were recorded also for the control group. Results: According to the results of Repeated Variance Analysis: time dependent changes were statistically significant (p:0.015) but, Time-Group interaction results were not statistically significant (p: 0.051). There was a statistically significant difference between the weight values according to the time intervals between the baseline values and 1.week and 1.month values; while there was not a statistically significant difference between the other time intervals. There was a statistically significant decrease in the mean weight values of treatment group according to the mean baseline values. Conclusion: Remarkable weight loss was observed in all patients in the first month of the treatment. Patients started to recover weight loss after second month of treatment.Amaç: Sabit ortodontik tedavinin ilk üç ayında gerçekleşen kilo değişimini değerlendirmek. Gereç ve Yöntemler: Sabit ortodontik tedaviye ihtiyaç duyan 53 hasta (12 erkek, 41 kadın) seçildi. Benzer koşullara sahip 50 birey(14 erkek ve 36 kadın) kontrol olarak seçildi. Kontrol grubunda yaş ortalaması 17.44 ± 0.75, tedavi grubunda 17.67 ± 0.85 idi. Tedavi başlangıcında, braketleme sonrası 1. hafta ve 1., 2. ve 3. ay düzenli şekilde hastaların kilo değerleri kaydedildi. Aynı değerler kontrol grubu için de kaydedildi. Bulgular: Tekrarlanan Varyans Analizi sonuçlarına göre zaman bağımlı değişmeler istatistiksel olarak anlamlıydı (p: 0.015), ancak Zaman-Grup etkileşimi sonuçları istatistiksel olarak anlamlı değildi (p: 0.051). Başlangıç değerleri ile 1. hafta ve 1. ay değerleri arasındaki zaman aralıklarına göre ağırlık değerleri arasında istatistiksel olarak anlamlı fark vardı; diğer zaman aralıkları arasında istatistiksel olarak anlamlı bir fark yoktu. Tedavi grubunun ortalama ağırlık değerlerinde, ortalama başlangıç değerlerine göre istatistiksel olarak önemli bir düşüş vardı. Sonuç: Tedavi gurubundaki tüm hastalarda tedavinin ilk ayında kayda değer kilo kaybı gözlendi. Tedavinin ikinci ayından sonra ise hastalar tekrar kilo almaya başlad
