The objectives of this study were to compare the maxillary canine impaction severity and orthodontic treatment difficulty in relation to age and gender. Orthopantomograms of 105 patients with maxillary canine impaction were retrospectively collected and divided into 50 adolescents (11–17 years; 30% females) and 55 young adults (18–25 years; 34% females). Canine impaction severity was determined using one angular and three linear radiographic measurements, while orthodontic treatment difficulty was determined using a modified Pitt et al. index. Age and gender differences were assessed using Chi-square with Bonferroni correction and Mann–Whitney U-tests (P < 0.05), while the association between orthodontic treatment difficulty index score and age was assessed using linear regression analysis (95% confidence interval). Compared to young adults, adolescents had mild (<30°) canine long axis to midline angulation (P = 0.008) and distally positioned cusp tip of impacted canine relative to adjacent lateral incisor root (P < 0.001). Meanwhile, males compared to females had distally positioned cusp tip of impacted canine relative to adjacent lateral incisor root (P = 0.008), while females compared to males had the canine cusp tip mesial to lateral incisor root (P = 0.002). The orthodontic treatment difficulty trend increased with age (R2 = 0.077; P < 001) and was higher in young adults than adolescents (P = 0.0218). The severity of maxillary canine impaction was higher in young adults and, to a lesser extent, in females. Orthodontic treatment difficulty of impacted maxillary canines also increased with age but not gender.

The study aimed to investigate the optimum level for the placement of ramal implants as a source of anchorage for disimpacting mandibular molars. The criteria in relation to the maximum transverse width of the ramal bone and proximity of the implant to the inferior alveolar canal (IAC) were evaluated using a three-dimensional cone-beam computed tomography scan for predictable placement of ramal implants. The cone-beam computed tomographic scans of 53 untreated patients (aged between 18 and 48 years) were utilized in this study. The maximum transverse width of the ramus and the proximity to the IAC from the site of insertion were measured at six different levels above the central groove of the mandibular first molar. To measure the proximity to the IAC, the mid-point of the maximum transverse width of the ramus was selected as the site of insertion of the implant. The maximum and minimum transverse ramal width was 12.48 ± 1.76 mm at 3 mm and 10.42 ± 2.08 mm at 8 mm above the central groove of the permanent mandibular first molar. An average clearance of 9.62 ± 2.59 mm was measured from the site of insertion to the IAC at the different levels evaluated. The ramus of the mandible can be a predictable site for implant placement provided the variations in the anatomical structures have been carefully analyzed. It can be concluded that the ramal implants can be safely placed at a level 3–8 mm above the permanent mandibular first molar in relation to the occlusal plane.

Using a single bone-borne maxillary appliance with twofold mechanics, that is, rapid palatal expander and nonfrictional distalizing appliance (Pendulum) is a valuable option to treat young-adult patients with poor compliance. In this particular case, the same appliance was used to disinclude 2.3, eliminating reaction forces on the arch. Therefore, the first expansive phase was followed by the distalizing phase. After enough space was obtained for the recovery of tooth 2.3, a triple-looped titanium-molybdenum alloy (TMA) spring was used to perform canine orthodontic traction. The core concept is that digital planning and optimal positioning of two palatal mini-screws can ensure a bicortical anchorage which, in turn, enabled to tolerate the different orthodontic phases. As a matter of fact, a tooth-bone-borne anchorage was followed by a pure bone-borne anchorage with no lost of stability.

The aim of the study was to assess the proficiency of clear aligners (CAs), and to evaluate all aspects of this orthodontic procedure including bleeding on probing (BOP), plaque index (PI), gingival index (GI), and probing pocket depth (PD), which all are clinical parameters of gingival inflammation in addition to the pain score. We performed an electronic search in the different databases such as Cochrane CENTRAL for eligible studies, SCOPUS, PubMed, and Web of Science. The quality of the involved trials has been measured according to Cochrane’s risk of bias tool. The following outcomes have been assumed: BOP, PI, GI, probing PD, and pain score. The homogeneous and heterogeneous data have been evaluated using random-effects model and fixed-effects model, consistently. Ten clinical trials have been included in the study. The pooled analysis that The CAs has been associated with a significant decrease in the pain score (standardized mean difference = 0.74 [0.46, 1.02]), (P = 0.0001). No significant variations between post-treatment and pre-treatment group were found regarding plaque index (mean difference [MD] = −0.11 [−0.45, 0.22]), (P = 0.5), BOP (MD = 0.20 [−0.01, 0.41]), (P = 0.06), GI (MD = 0.17 [−0.06, 0.40]), (P = 0.15), and BOP (MD = 0.01 [−0.16, 0.17]), (P = 0.94). Patients treated by CAs showed a noticeable decrease in pain scores. On contrary, there was not any difference between the pre-treatment data and post-treatment data regarding other indices.

The study aimed to compare the shear bond strength (SBS) of three orthodontic adhesives with integrated primer, with those of self-etching and conventional bonding adhesives. One hundred extracted premolars were randomly allocated to five groups. Brackets were bonded using three adhesives with integrated primer (GC Ortho Connect™, Biofix, and Orthocem). A group of brackets was bonded with the conventional bonding procedure (Transbond XT) and one group was bonded with a self-etching primer (Transbond™ Plus). All samples were subjected to thermal aging (5000 cycles: At 5°C and 55°C media). The compressive strength test was performed and the maximum load when the bracket detached was recorded. The amount of residual adhesive (ARI) remaining on the tooth surface was assessed visually. Significantly higher SBS values were recorded with the conventional technique (14.01 ± 5.79 megapascals [MPa]), compared to other groups except for GC Ortho Connect™ (11.86 ± 3.83 MPa). There was no significant difference between the self-etching group and the groups containing integrated primer samples. However, one of the adhesives with integrated primer presented SBS values near-slightly below the limit considered clinically successful (7.65 ± 3.71 MPa). The ARI scores varied between adhesive groups; GC Ortho Connect™ and the self-etching primer samples showed statistically significantly higher scores compared to the three other groups. Clinically successful bonding values were achieved with two out of three different adhesives with integrated primer. One of the adhesives with integrated primer provided a similar SBS value to the tri-step conventional bonding procedure. ARI scores varied independently from SBS values.

Our work aims to provide scientific evidence by conducting a serious systematic review of the efficacy of three-dimensional (3D) anchorage devices for orthodontic traction of impacted maxillary canines. An electronic search extending from 2012 to 2022, targeting mainly clinical trials was performed on the following databases PUBMED (MEDLINE), The Cochrane Library, SCIENCE DIRECT, EBSCO HOST DATABASES, and GOOGLE SCHOLAR. The search was established on a well-defined research question following the PICO principle: population, intervention, comparator, and outcome. Search evaluation and the assessment of the risk of bias (RoB) were undertaken in each study following its type and design. Thirteen studies were included for qualitative analysis, with a low to moderate RoB. Ten studies used only heavy conventional palatal anchorage such as a fixed trans palatal arch (TPA), while one study used skeletal anchorage to manage the orthodontic traction of impacted maxillary canines. Two studies compared trans palatal arch and mini-screws efficiency to treat impacted maxillary canines. Studies proved that the trans palatal arch (TPA) presents a particular anchorage unpredictability in the sagittal, transversal, and vertical dimensions. Whereas, anchorage management using mini-screws proved to be very beneficial clinically; however, further studies must be implemented to evaluate the 3D efficacy of skeletal anchorage to place an impacted maxillary canine to its rightful position into the arch.

The aim of this study is to examine the relationship between occlusal factors and temporomandibular joint diseases (TMD). In our study, 43 individuals who had fixed orthodontic treatment and 20 individuals who did not need treatment at Istanbul Aydin University Faculty of Dentistry Department of Orthodontics were included in the study. Evaluations were made at the beginning of treatment (T0) and at 6 months (T1). T-Scan® computerized Occlusion Analyzer was used to evaluate the number of contact points, occlusal force parameters during centric occlusion and lateral movements, and occlusion and disclusion times. Differences between groups were evaluated with Mann–Whitney or independent t-test, and within-group differences were evaluated with Wilcoxon sign test or paired t-test, depending on whether the data showed normal distribution or not. There was no statistically significant distinction between the gender-based parameters and right and left joint of Joint Vibration Analysis record in all three groups (P > 0.05). At the beginning of orthodontic treatment, there was no statistical difference in the variables within the group and between the groups. As a result of the comparison between the beginning of treatment (T0) and the 6th month (T1), no significant difference was found between the parameters of the anterior/posterior occlusal force distribution of the right-left quadrant and the force distribution of the working and non-working sides in lateral movements, and the occlusion and disclusion time parameters. Maximum intercuspal position left/right (MxlntlTSCANT1) was found to be statistically significant at 6 months in individuals who received fixed orthodontic treatment with extraction compared to the none xtraction treatment group (P < 0.05). According to our research, T-scan is one of the best devices for the early detection of TMD, especially for people undergoing orthodontic treatment. T-scan offers fast, non-invasive, and repeatable occlusion recording.

A questionnaire, specific to the clinical condition treated is important. The aim of this study was to evaluate the Quality of life (QOL) amongst patients undergoing orthognathic surgery using a customized questionnaire encompassing, patients’ perception of facial form and also patient perception of overall quality of care provided during the entire treatment. This prospective, qualitative, observational study was carried out on 21 patients, who underwent Ortho-surgical management between Jan 2019 and Mar 2020. The Orthognathic QOL questionnaire was customized, Phase I, immediately prior; and Phase II, 6 months after surgery. Appropriate analysis was done to compare Phase I and Phase II, with the level of significance set to P < 0.05. “Aesthetics” was the most frequent reported reason for seeking treatment. The mean pre-/post-treatment difference for oral function was statistically significant. Majority (87%) of patients reported surgical outcomes met their expectations. Results, post-surgery; good hospital care (33.3%), supportive doctors (28.57%) and regular follow up (9.52%). “Patients’ perspective” of treatment, is often neglected, the immense importance of which has been duly reflected in our study. We recommend the use of our questionnaire in a similar, broad based multicentric study with a larger patient base, will aid in improving overall outcome of ortho-surgical interventions.

Appropriate analysis was done to compare Phase I and Phase II, with the level of significance set to P < 0.05.\u0000\u0000\u0000\u0000“Aesthetics” was the most frequent reported reason for seeking treatment. The mean pre-/post-treatment difference for oral function was statistically significant. Majority (87%) of patients reported surgical outcomes met their expectations. Results, post-surgery; good hospital care (33.3%), supportive doctors (28.57%) and regular follow up (9.52%).\u0000\u0000\u0000\u0000“Patients’ perspective” of treatment, is often neglected, the immense importance of which has been duly reflected in our study. We recommend the use of our questionnaire in a similar, broad based multicentric study with a larger patient base, will aid in improving overall outcome of ortho-surgical interventions.\u0000","PeriodicalId":42593,"journal":{"name":"APOS Trends in Orthodontics","volume":"67 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2023-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91120704","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
The objectives of the study were to evaluate and compare the antimicrobial property of nanochitosan coated and uncoated stainless steel (SS) brackets against Streptococcus mutans and Lactobacillus acidophilus. 22 SS orthodontic brackets coated with nanochitosan and 22 uncoated brackets were bonded to the crowns of extracted premolar teeth and prepared for the antimicrobial assay against S. mutans and L. acidophilus. The bacterial suspensions were incubated in Mueller Hinton broth and cultivated in Petri dish plates. The bacterial colonies were counted after 1, 6, 12, 24, and 72 h intervals using a digital colony counter. Inter and intragroup comparisons were done using independent sample t-test and repeated measures ANOVA (P ≤ 0.05). The mean colony-forming units (CFU) of S. mutans and L. acidophilus showed a significant reduction in the coated brackets from 1 h to 72 h (P = 0.000). The mean CFU of S. mutans and L. acidophilus showed a significant increase in the uncoated brackets from 1 h to 24 h and decreased thereafter at 72 h (P = 0.000) except for S. mutans between 12 h and 72 h where the difference was not statistically significant (P = 0.837). The Mean CFU of S. mutans and L. acidophilus was significantly lesser in coated brackets compared to uncoated brackets at all-time intervals (P = 0.000). Nanochitosan coated orthodontic brackets showed significant antimicrobial properties against S. mutans and L. acidophilus in short-term up to 72 h compared to uncoated SS brackets.

The purpose of this study was to evaluate the amount of root repair that took place at varying intervals of 1 day, 2 weeks, 4 weeks and 8 weeks after intentional contact with microscrews. The results were evaluated by an environmental scanning electron microscope study (E-SEM). Ten orthodontic patients with 2 maxillary and 2 mandibular first premolars (40 premolars) to be extracted as part of the orthodontic treatment were included in this study (age 18–25 years). The position of the roots of the 4 premolars to be extracted was clinically determined and under local anesthesia, microscrew implants were placed in such a way that they directly hit the root from the buccal aspect. Implants were removed immediately after the above-mentioned procedure was performed. On the same day, premolar of the 1st quadrant (Group I) was extracted. Premolar of the 2nd quadrant (Group II) was extracted 2 weeks later. Premolar of the 3rd quadrant (Group III) was extracted 4 weeks later and premolar of the 4th quadrant (Group IV) was extracted 8 weeks later, from the day of intentional damage. Significant changes were observed in the deposition of cementum over 8 weeks which were analyzed using ESEM under magnifications of × 50, × 200, × 500, and × 5000. The damaged root surfaces due to intentional contact with microscrews showed swift repair and healing within 8 weeks. In case, the root is damaged due to improper placement technique or wrong biomechanics which may result in the implant touching the root surface, a minimum healing period of 8–10 weeks is advocated before commencing further tooth movement.
