An interrelation between the level of difficulty of canine impaction based on its three-dimensional position and the degree of root resorption of the adjacent teeth improves the quality of orthodontic treatment planning. It would be advantageous for clinicians to know the predilection of resorption in varying canine positions. The aim of the study is to evaluate and correlate the severity of root resorption of adjacent teeth and the level of difficulty of impacted canine classified by KPG Index and sector analysis using cone-beam computed tomography. The study sample comprised 48 impacted canines in orthodontic patients (17 boys and 27 girls) with a mean age of 24 years. The cone-beam computed tomographs were evaluated using Dolphin Imaging Software and primarily, three observations were recorded: KPG index, sector analysis, and root resorption. The samples were equally divided into four groups based on the KPG index, with 12 samples in each group. Additionally, the inclination of the canine in the frontal plane and their degree of vertical eruption were recorded. The number and severity of resorptive lesions increased as the KPG score escalated. The mean KPG score was 13.67 ± 6.336 and the average KPG index was 2.5 ± 1.13. A statistically significant positive correlation was found between all the parameters and root resorption. A positive correlation exists between the level of difficulty of canine impaction and root resorption of the adjacent teeth. A KPG score higher than 13.67 can be a resourceful predictor of resorptive lesions. An increased tendency of root resorption of the neighboring teeth was observed when angle α and angle β exceed 43.71° and 43.26°, respectively.

The present study aimed to analyze the outcomes of Furlow double-opposing Z-plasty techniques and to know the effect of this technique on arch dimensions and also to compare these outcomes with the ordinary technique (pushback technique) and with the control group. There are two treatment groups and one control group. Forty-two (20 males and 22 females) patients as a total number of the sample with unilateral cleft lip and palate (UCLP) children were included in this study, 1st group (10 males and 14 females) those treated with Furlow double-opposing Z-plasty performed at the age of 10 weeks repair of the lip, at 10 months closure of soft palate followed by construction of obturator done by an orthodontist, at 6 years of patient`s age a closure of hard palate, 2nd group (10 males and 8 females) treated with pushback technique. Criteria for selecting patients (two treatment groups), those without systemic diseases, cerebral disabilities, or any syndromes. The 3rd group consists of 20 healthy children (10 males and 10 females) those free from systemic diseases, aged 9–10 years old, free from oral habits and with limited or no crowding of teeth. Impressions of the upper arch of the patients were taken and the study model was poured at ages 9–10 years. Measurements include anterior arch width (ARW) or intercanine distance, posterior arch width (PAW) or intermolar distance, and arch depth (Adp). Statistical analysis; after collecting the data SPSS software program (version no. 21 Chicago, Illinois, USA) used for analysis, P ≤ 0.05 will be considered as statistically significant. The data were analyzed for their normal distribution, and a comparison of dental arch dimensions between genders and between the two techniques of surgical repair was tested by independent t-test of samples. Significant larger mean values for arch measurements ARW and Adp for males and Adp for females than with the pushback technique. This is related to the growth pattern that occurred without surgical intervention. An improvement in surgical outcomes, and the patients with UCLP treated with Z-plasty technique, revealed an increase in the mean values of arch measurements (anterior and PAW and Adp) for both genders when compared to the pushback technique, but less than that of healthy non-cleft children.

Klippel-Trenaunay syndrome (KTS) is a congenital disorder characterized by a clinical triad of capillary malformation; varicose veins; and soft tissue and/or bony hypertrophy. This rare syndrome has an estimated incidence of about 2–5/100,000 live births. KTS usually affects the extremities but occasionally can manifest in the craniofacial region, including the oral cavity. Our patient, a 17-year-old girl, presented with large areas of port wine stain, unilateral hypertrophy of the facial region, and varicose veins. She was diagnosed with KTS. Orthodontic treatment followed by orthognathic surgery was performed to address her complaint of facial asymmetry and poor chewing efficacy. Treatment resulted in significant improvement in her appearance and dental occlusion and our patient was very satisfied with the results. This report illustrates an orthodontic and surgical treatment approach of a case with KTS. Effective management of orthodontic and facial manifestations of KTS considerably enhances the patient’s function, appearance, and overall quality of life.

Over the last two decades, clear aligners have become a mainstay in contemporary orthodontic practice primarily due to improvements in digital and 3D printing technologies, a growing interest in esthetic orthodontics, especially in the adult population, and aggressive manufacturer marketing internationally. PubMed, Google Scholar, Cochrane Library, and EMBASE databases were searched from January 1998 to November 2021. The search terms used were “Invisalign” OR “clear aligner.” A total of 7000 records were searched, of which 369 potentially relevant articles were retrieved in full. 190 studies met the selection criteria following screening and were included in the scoping review. This review scopes and analyses published orthodontic literature about CA according to a year-wise distribution into 3 groups, 2001–2010/2011–2020/2021. Most of the studies were published in the period between 2011 and 2020, with 138 studies accounting for 73%. The year 2021 followed, with 31 studies accounting for 16%, which was greater than the number of studies published in 10 years from 2001 to 2010. Studies were also classified based on the study designs with most of the published studies representing the lowest level of evidence including case reports, case series, narrative reviews, expert opinions, and editorials accounting for 137 studies, whereas case-control studies were the least reported studies with only 4 studies reported in the literature. In addition, they were categorized into seven main domains: (1) Biological considerations associated with clear aligner therapy (CAT), (2) Treatment outcomes considerations associated with CAT, (3) Geometrical considerations associated with CAT (clinical), (4) Biomechanical considerations associated with CAT (Laboratory/Finite element analysis), (5) Biomaterial considerations associated with CAT, (6) Patient education and experience and aesthetic and social perception of CAT, and (7) Miscellaneous. Treatment outcome considerations associated with CAT had the greatest percentage representing 36% of the total published domains, while the final place was occupied by the biomechanical considerations associated with CAT accounting for only 4% of the published domains about CAT. Treatment outcome was the domain most commonly reported by studies accounting for (36%). Most of the published studies are at the lowest level of evidence including case reports, case series, narrative reviews, and expert opinions. The vast majority of studies utilized only a single clear aligner brand. There is a greater need for research that studies CAT from a holistic perspective.

The objective of this study was to analyze the divine proportion of lips position related to the overall face. Normative proportions were sketched in seven patterns of face on milimeter graph paper, where specific anatomical points were determined. No subjects participated in the study. The facial length was segmented into the golden ratio at point Phi (Divine proportion). Specific distances within the minor inferior subsection of the face, involving the lower and upper lips, were studied. The one-sample t-test was used to compare the means to the normative constant. The distance from Phi to the lower lip was 52% of the minor inferior facial section. The means of quotients relating lower and upper lips with point Phi were not statistically different to constant 1.618. The lower lip stands in the midpoint of the minor inferior facial section and the divine proportion was found in the position of lips within the overall face. In a time when much importance is given to lips condition, it is suitable to the orthodontist and general dentists to recognize its natural positions on a regular basis.

The purpose of this study was to evaluate whether there is a relationship between the alignment or misalignment of the marginal ridges of posterior teeth and the degree of resorption of interproximal alveolar bone. Intraoral scans and bitewing radiographs were performed on 50 subjects. The bitewing radiographs were analyzed using the VixWinTM Platinum software, measuring the distance between the cementitious junction and the alveolar ridge at the interproximal level for 32 sites for each patient, defined as bitewing scores. The digital models have been oriented in the three dimensions using the Rhinoceros 3D and the linear distance between two contiguous marginal ridges was measured for each interproximal space. To estimate the entity of the correlation, a separate linear regression was performed on the bitewing score for each mouth quadrant. Using the t-test the significance of each estimated coefficient was determinate (P < 0.05). In the general comparison including all the analyzed elements, the independent variables are partially correlated with each other. Apparently, the relationship between independent and dependent variables appears to be insignificant. Comparing groups of teeth, however, there seems to be a statistically significant correlation (P < 0.05) between canine and lower first premolar in the XZ and YZ planes and between lower first and second molars in the three dimensions. There seems to be a poor correlation at a general level between periodontal conditions of the alveolar bone and the degree of alignment of the marginal ridges.

This case report presents the management of an adult patient with moderate crowding in both arches and anterior crossbite with passive self-ligating lingual brackets. The orthodontic setup and bracket positioning was done digitally with an in-house approach. Virtual setup and bracket placement was performed on Autolign software (Diorco, Gyeonggi-do, Korea). The indirect bonding trays were vacuum-formed on printed malocclusion models with resin brackets. Two palatal and two buccal shelf miniscrews were used for two-arch distalization to correct proclined incisors and anterior open bite after leveling and alignment stage. After 12-month treatment, normal overbite,overjet and well-aligned dentition were achieved without premolar extraction. The incisors were uprighted slightly and the protrusive lower lip was retracted with improvement of facial harmony. One-year retention records confirmed that the outcome was stable. In-house digital setup and bracket placement could be a cost-effective approach for indirect lingual bracket bonding. Two-arch distalization with miniscrew anchorage may have the possibility of managing moderate crowding cases without premolar extraction or interproximal stripping.

The objectives of this study were to evaluate how orthodontic treatment type, treatment need, and depression affect perceived pain intensity (PPI). This prospective study included 172 patients (80 girls and 92 boys, mean age 14.32 ± 1.57 years) treated at the Sivas Cumhuriyet University Faculty of Dentistry, Department of Orthodontics. The patients were divided into three groups: the first group was treated with fixed orthodontic appliances, the second group was treated with twin blocks, and the third group was treated with rapid maxillary expansion and reverse headgear (RME/RH). Data were collected and classified with the Index of Orthodontic Treatment Need-Dental Health Component (DHC), Children’s Depression Scale, and Visual Analog Scale. PPI was recorded in the 1st week (T0), 2nd week (T1), the 1st month (T2), 2nd month (T3), 3rd month (T4), and the 6th month (T5). PPI was higher in boys at T1 (P = 0.005) compared with girls. There was a significant difference of PPI between the treatment groups at T2 (P = 0.036), T3 (P = 0.012), T4 (P = 0.000), and T5 (P = 0.006). A statistically significant positive correlation was found between DHC and PPI at T3 (r = 0.182; P = 0.000), T4 (r = 0.161; P = 0.03), and T5 (r = 0.189; P = 0.000) time periods. There was no significant correlation between depression and PPI. Girls were more resistant to pain than boys. The type of treatment and the need for treatment both had an effect on PPI.

The patients were divided into three groups: the first group was treated with fixed orthodontic appliances, the second group was treated with twin blocks, and the third group was treated with rapid maxillary expansion and reverse headgear (RME/RH). Data were collected and classified with the Index of Orthodontic Treatment Need-Dental Health Component (DHC), Children’s Depression Scale, and Visual Analog Scale.

The study aimed to systematically investigate the effect of skeletal anchorage on mandibular rotation during FFA therapy during Class II correction in adolescents. The review protocol was registered under the PROSPERO database (CRD42021256690). Electronic searches of databases and screening were performed up to May 2022. Only randomized clinical trials (RCT) and non-randomized controlled trials (non-RCT) were included in the study. Revised Cochrane risk-of-bias tool for RCTs (RoB 2) and risk of bias in non-randomized studies-of interventions tool for non-RCT were used for studies. Meta-analysis was performed and a forest plot was obtained. The primary outcome was mandibular rotation. Other outcomes assessed were angles SNA, SNB, ANB, mandibular incisor proclination, and failure rates of mini-screws and mini plates. Twelve studies (eight RCTs and four non-RCTs) were included fulfilling inclusion criteria. Evidence showed a low-to-moderate risk of bias for different domains. Meta-analysis for mandibular rotation revealed a greater increase in mandibular plane angle in patients who received FFA with skeletal anchorage as compared to patients who did not receive skeletal anchorage. With or without skeletal anchorage, mandibular rotational changes during FFA therapy are similar. FFA when combined with skeletal anchorage causes more skeletal changes in sagittal parameters than conventional FFA used alone. FFA with skeletal anchorage reduces lower incisor proclination.

This study aimed to content quality analysis of YouTube videos about aligners in orthodontics by a dentist and by an orthodontist. Considering the Google Trends analysis, the “aligner,” as the most searched keyword about aligners in orthodontics, was chosen for YouTube searching. A total of 39 included videos were watched for one time by a dentist and orthodontist. Time since upload, video duration, number of views, number of likes, number of dislikes, and number of comments were recorded. Moreover, the interaction index and viewing rate were calculated and the reliability score, video content quality (VCQ), video interaction and quality index (VIQI), and global quality scales (GQS) were recorded by both viewers. Interobserver agreement levels were interpreted with the Concordance Correlation Coefficient (CCC) and data were evaluated at P < 0.05 as the statistically significant level. The results showed that most of the included videos (48.71%) were uploaded by dental companies. However, the averages of VCQ in terms of uploaders were similar for both viewers. The agreement level in all videos between orthodontist and dentist was “good” level at VIQI (CCC = 0.965) and GQS (CCC = 0.943), whereas it was “very poor” level on VCQ (CCC = 0.653). The findings revealed that YouTube video contents about aligners provide moderate information and VCQ, independently from viewers, is similar among uploaders. The agreement levels between dentist and orthodontist on the evaluation of audiovisual quality of the videos were good, whereas this level was poor on the evaluation of information quality of videos.
