Our primary objective was to establish the efficacy of fluoride gel and fluoride varnish in the prevention of white spot lesions (WSLs) development during fixed orthodontic treatment. The study sample consisted of 60 adult patients in a prospective split-mouth study design. Interventions, that is, topical fluoride gel and topical fluoride varnish were assigned at the time of bonding to either the right or left halves of the dentition. In all subjects, repeated evaluation of demineralization was done on the facial surfaces of sample teeth in each quadrant. Evaluation using laser fluorescence and by direct visual observation under magnification was carried out at bonding (T0), 3 months (T1), and 6 months (T2). The distribution of mean DIAGNOdent score at T1 (3.14 ± 1.00 vs. 2.81 ± 0.852) and T2 (4.17 ± 1.41 vs. 3.51 ± 1.13) was observed which is significantly higher in the Gel group compared to the Varnish group. In the Gel group, the distribution of mean DIAGNOdent score at T1 (3.14 ± 1.00) and T2 (4.17 ± 1.41) is significantly higher compared to mean DIAGNOdent score at baseline T0 (2.07 ± 0.66). In the Varnish group, the distribution of mean DIAGNOdent score at T1 (2.81 ± 0.852) and T2 (3.51 ± 1.13) is significantly higher compared to the mean DIAGNOdent score at T0 (2.07 ± 0.66). Visual scores also correlated with DIAGNOdent scores. Fluoride varnish is more efficacious than fluoride gel in reducing enamel demineralization. Initial application of fluoride varnish around the orthodontic bracket at bonding appointment can offer significant protection against WSLs.

The purpose of this study was to evaluate the facial soft tissue and craniofacial morphological structures in adolescent obese individuals with different skeletal patterns. The study was carried out on 292 adolescents examined under three groups based on their body mass indexes (BMIs) as obese, healthy, and overweight. The subjects were also categorized based on skeletal classes as Class I, Class II, and Class III. The glabella, nasion, labiale inferius, labiomentale, and pogonion values of the female patients were significantly higher in obese group. In the obese and overweight groups, effective midfacial and mandibular length, anterior and posterior facial heights, and SN values of the females were higher than males. In the obese group, the mean effective midfacial and mandibular length (Co-A and Co-Gn), anterior and posterior facial heights (S-Go and N-Me), and anterior cranial base (SN) values were significantly higher than other groups. Soft-tissue thicknesses increase as BMI value increases. Craniofacial morphology reveals significant differences between BMI groups.

Maxillary impacted canines have an important place in orthodontics for the reason of being a common anomaly and its treatment is time consuming and difficult. The aim of this study was to investigate the mandibular indexes and cephalometric parameters in adolescents with impacted maxillary canines. The radiographs of 4026 patients aged 12–19 years old were scanned and a total of 155 patients were included in the study. Subjects were divided into three groups according to the permanent maxillary canines: Bilateral impacted canine (BIC) (52 subjects; mean age 15.02 ± 1.74 years), unilaterally impacted canine (UIC) (51 subjects; mean age 14.89 ± 1.39 years), and the control (52 subjects; mean age 14.84 ± 1.65 years) groups. Skeletal, soft tissue and dental measurements were performed on cephalometric radiographs. Mandibular index analyzes including the panoramic mandibular index (PMI), mental index (MI), antegonial index (AI), and gonial index (GI) measurements and also angular measurements of impacted maxillary canines were performed on panoramic radiographs. Data were analyzed statistically and P < 0.05 was considered significant. Maxillary skeletal and dental measurements showed retrusive positioned maxillary dental arch in the sagittal direction in the impacted canine groups (P < 0.05). PMI and MI values were greater in the BIC and UIC groups than in control group (P < 0.05). There was no statistically significant difference in AI value among groups (P < 0.05). GI value of BIC group was found statistically lower than other groups (P < 0.05). Individuals with impacted maxillary canines have more retrusive maxillary dental arch and soft-tissue components. Furthermore, mandibular cortex was thicker in subjects with impacted maxillary canine than individuals with not and clinicians should keep in mind this when examine the panoramic radiographs in terms of early diagnosis of impacted maxillary canine teeth.

The aim of this study was to investigate the effect of pain caused by orthodontic fixed appliances on sleep quality of participants using the Pittsburgh Sleep Quality Index (PSQI). A previously validated Arabic version of PSQI was electronically distributed through different social media platforms and in waiting areas of orthodontic offices. Eligibility criteria included healthy adults and adolescents with orthodontic fixed appliances and with no systemic conditions that may affect sleep. The cut-off point used to determine poor sleep quality was (>5). Three hundred and eighteen participants were included in the final analysis (28.9% males and 71.1% females). Both males and females with orthodontic fixed appliances had poor sleep quality with (Mean = 6.48, SD = 2.85, P = 0.000) for males, and (Mean = 7.18, SD = 2.87, P = 0.000) for females. Comparing males and females, we found that females scored higher than males in both subjective sleep quality and PSQI global score. Individuals undergoing orthodontic treatment with fixed appliances have poor sleep quality. Females undergoing orthodontic treatment tend to have poorer sleep quality compared to males.
本研究的目的是利用匹兹堡睡眠质量指数(PSQI)调查正畸固定器具引起的疼痛对参与者睡眠质量的影响。先前经过验证的阿拉伯语版PSQI通过不同的社交媒体平台和正畸诊所的等候区以电子方式分发。入选标准包括健康成人和青少年，使用正畸固定矫治器，无可能影响睡眠的全身性疾病。判定睡眠质量差的分界点为(>5)。最终分析纳入318名参与者(28.9%为男性，71.1%为女性)。使用正畸固定矫治器的男女睡眠质量均较差，男性(Mean = 6.48, SD = 2.85, P = 0.000)，女性(Mean = 7.18, SD = 2.87, P = 0.000)。比较男性和女性，我们发现女性在主观睡眠质量和PSQI总体得分上都高于男性。使用固定矫治器进行正畸治疗的人睡眠质量较差。与男性相比，接受正畸治疗的女性往往睡眠质量较差。

The aim of this review is to systematically analyze the efficacy of molar distalization using clear aligners in non-growing Class II patients. A complete search across the electronic database through PubMed, Cochrane, Google scholar, LILACS, and manual search of orthodontic journals were done till 2019. Studies were selected on the basis of PRISMA guidelines. A total of four articles were included in this review. The amount of molar distalization reported was 2–3 mm. Out of the four studies included. In all the studies a significant amount of distalization was reported. Three retrospective studies concluded that distalization with aligners is the most effective of all tooth movements. One study concluded that aligners effectively achieved distalization with an efficacy of 87%, other two studies concluded that aligners effectively distalized the molars with good control over vertical dimension and mesiodistal tipping.

The objectives of the study were to assess, measure, and correlate the maxillary and mandibular effective base length, arch length to the amount of dental crowding in different vertical growth pattern patients. Sample comprising 100 pre-treatment lateral cephalograms and study models (age group – 16–25 years) was randomly selected. The sample was divided into two groups, that is, clockwise (50) and anticlockwise (50) rotation based on the measurement of the gonial angle. The gonial angle and maxillary and mandibular effective lengths were measured on pre-treatment lateral cephalograms. Dental crowding and arch length were measured on the pre-treatment dental casts. Intergroup comparisons of effective base length, arch length, and crowding were performed with unpaired t-tests. Correlations between effective base length, arch length, and dental crowding were examined by means of Pearson’s correlation coefficient (P < 0.05). Subjects with clockwise rotation significantly had more mandibular dental crowding and significantly decreased mandibular arch length compared to the anticlockwise group. An inverse correlation was found between maxillary and mandibular effective base length, arch length, and dental crowding while a positive correlation was found between maxillary and mandibular base length and arch length in both the groups. Clockwise rotation of the mandible along with skeletal and dental factors such as decreased effective base lengths and arch length, respectively, constitutes an important factor leading to dental crowding.

This review synthesizes the available evidence about the individual skeletal maturity with biological maturity indicators and compares it with the levels of gingival crevicular fluid (GCF) alkaline phosphatase (ALP) activity in growing children. This systematic review aimed to clarify the question: Is GCF ALP a reliable biomarker to assess skeletal maturity during growth? The objective of this systematic review is to collect, compile, and review the existing evidence on the levels of GCF ALP activity in growing children and comparing its reliability with contemporary growth indicators. A literature appraisal executed using Entres PubMed, www.ncbi.nim.nih.gov, Scupose, Hinary, Ebsco, Embass, Cochrane; Google Scholar Electronic database search engines were used. The MeSH term used “growth markers in gingival crevicular fluid” or “growth markers in growing children.” Studies published till October, 2020, were included in this study. The data have extracted from the selected articles based on year of publication, study design, age of subjects, instruments used, and author’s conclusions. The quality assessment was executed using BIOCROSS Scale. This scale is exclusive for cross-sectional studies with biomarkers. Literature search identified 731 records from electronic databases and from the partial grey literature (Google scholar) search. Finally, six articles fulfilled eligibility criteria included in the review. All the six studies concluded that GCF ALP activity is a reliable method in determining a skeletal maturity indicator in growing children.

The aim of the present study was to compare parents’ perceptions of their children’s malocclusion and clinician-measured normative orthodontic treatment need with the socioeconomic status of the parents as a means of assessing whether demand for treatment is uniform across socioeconomic groups. In this cross-sectional study, 212 (125 girls and 87 boys) subjects between the ages of 8 and 25 years (mean age 17.03 ± 3.9) were assessed. The parents were asked to score the dental attractiveness of their children and their socioeconomic status (SES) based on the aesthetic component (AC) of the Index of Orthodontic Treatment Need (IOTN) and the modified Kuppuswamy scale (2018), respectively. The subjects recorded their self-perception using the OASIS scale. These scores were then compared within themselves and with those of the clinician who also scored the Dental Health Component (DHC) and AC of the IOTN. The AC grade of the IOTN and parents’ SES was tested with the Chi-square test. The association between the AC scores of the IOTN, DHC, and the characteristics of the subjects was tested with Spearman’s correlation coefficient (rho). Treatment uptake was uniform throughout the different socioeconomic groups. Association between the SES group and DHC group and clinician-measured AC were statistically not significant (P = 0.3958), (P = 0.3447). Parents, in this study population, irrespective of their socioeconomic status rated their children’s orthodontic treatment need less severely than the clinician (P = 0.0001). Severity of malocclusion as measured by DHC was much higher in male subjects than in females (P = 0.0348). Socioeconomic status of the parents did not seem to affect their perception of dental appearance. Self-perception of appearance and perceived treatment need was uniform throughout the different socioeconomic groups.

Missing or compromised permanent molars can complicate orthodontic treatment planning and mechanics. Molar extraction should be considered in appropriate situations, but clinicians must decide between closing and regaining the edentulous space. Several factors should be taken into consideration to achieve appropriate molar space management, such as the need for space, asymmetry, periodontal status, sinus pneumatization, and the terminal molar position. Herein, three sample cases are reported to demonstrate the treatment options for molar space closure and maintenance with these factors taken into consideration during treatment planning. The understanding of mechanics played a crucial role in anchorage preparation and side effect prevention. If the third molar substitution was managed in advance and adequate space between the ramus and third molar was obtained via second molar protraction, the tooth spontaneously erupted in a favorable position without requiring further treatment. This case series can aid clinicians in molar space management. Regardless of whether the space is to be closed or regained, the treatment plan should conform to the patient’s expectations and improve occlusion with minimal side effects and treatment duration.

The bracketless orthodontic treatment (BOT) is an alternative technique which indicates using an orthodontic appliance composed of wires and composite resin assisted by 3D technology. However, the biomechanical response of central incisor orthodontic movement has yet to be investigated. Thus, the aim of the present investigation was to calculate the stress magnitude in central incisor movement through 3D finite element analysis using different wire diameters (0.012”, 0.014”, and 0.016”) of nickel–titanium wire and two different resin composites (Opallis and Filtek). A 3D volume composed of enamel, dentin, cortical bone, cancellous bone, periodontal ligament, composite resin, and different orthodontic wire diameters was designed. After the modeling process, the models were exported to computer-aided engineering software divided into a finite number of elements, and a mechanical structural static analysis was conducted. The stress results were plotted on colorimetric maps and in tables for comparison between the different models. The results showed that the central incisor orthodontic movement with BOT does not induce damage to the periodontal ligament, dental root, or bone tissue, regardless of the simulated orthodontic wire diameter and resin composite materials. The palatal composite resin and orthodontic wire also presented acceptable stress magnitude during orthodontic movement. Thus, the BOT technique promoted a suitable biomechanical response during central incisor movement regardless the resin composite.
