Aim: This study aimed to compare the treatment progress and complications between patients receiving conventional orthodontic treatment and clear aligners during the coronavirus disease-2019 (COVID-19) pandemic.
Methods: An electronic survey was distributed randomly among orthodontic patients in Saudi Arabia to understand how the global health crisis caused by COVID-19 affected orthodontic patients. The survey questions were structured into four sections, including demographic data, continuation of orthodontic follow-up appointments during the COVID-19, reasons for missed appointments, and problems of orthodontic patients. Data analysis consisted of simple descriptive statistics presented in frequency tables and percentages. Statistical significance was set at P≤0.05.
Results: A total of 512 electronic responses were received. Sixty-two (12.11%) participants missed no orthodontic follow-up appointment during the COVID-19 lockdown. Hence, the study included 450 (87.89%) participants to evaluate the impact of COVID-19 pandemic on sustained orthodontic treatment. The proportion of patients in the fixed appliance group (35.2%, 86 patients) who responded that “they had not even once tried to communicate with their orthodontists” was significantly higher than that in the clear aligner group (9.2%, 19 patients) (P<0.001). The proportion of participants who received fixed appliances (62.3%, 152 patients) and disagreed with the lockdown of orthodontic clinics during the COVID-19 was significantly higher than that in clear aligner users (19.4%, 40 patients) (P<0.001).
Conclusion: The results indicated that most issues were reported by patients who had fixed appliances. Thus, tele-orthodontics could provide a solution to continue dental practice during the COVID-19, and clear aligners are preferable to traditional orthodontic treatment methods.

Aim: Orthodontic treatment often leads to gingival hyperplasia, which may complicate oral hygiene and necessitate surgical interventions such as gingivectomy. This study compared the efficacy of ceramic burs versus scalpels in gingivectomy procedures for orthodontic patients, focusing on periodontal outcomes and pain.
Methods: This case series describes six orthodontic patients with gingival hyperplasia. The patients were between 15-25 years and were non-smokers. They underwent gingivectomy using two methods: ceramic burs (NTI® Soft Tissue Trimmers) and traditional scalpels. Preoperative oral hygiene instructions were given, and intraoral photographs were obtained. Clinical measurements included the plaque index (PI), gingival index (GI), and bleeding index (BI). Bleeding, pain (using a visual analog scale), and periodontal indices were assessed at several time points postoperatively.
Results: Both groups showed significant improvements in gingival hyperplasia, PI, and mean GI. However, the ceramic bur group experienced lower postoperative pain compared to the scalpel group. One patient in the scalpel group required analgesics for pain management. The results highlighted the effective management of gingival hyperplasia with both methods but with a potential advantage in pain management for the ceramic bur group.
Conclusion: This study indicated that both ceramic burs and scalpels are effective for gingivectomy in orthodontic patients. Ceramic burs might offer a less painful alternative, although both methods effectively manage gingival hyperplasia. Further studies with a larger sample size and longer follow-ups are required to confirm the present findings and potentially recommend ceramic burs as a preferred method for gingivectomy.

Background and Aim: Assessing the midpalatal suture (MPS) maturation is crucial to successfully predict rapid maxillary expansion (RME). Therefore, radiographic measurement of the suture width is vital for treatment planning. This study compared MPS ossification using cross-sectional maxillary occlusal radiographs and cone-beam computed tomography (CBCT) scans to aid clinicians in making better informed treatment decisions.
Methods: In this study, 33 patients were selected as the study cohort and were categorized into two distinct groups according to their chronological age. Group I included individuals in the growth phase, aged between 8 to 16 years, while Group II encompassed post-adolescent and young adult participants aged between 16 to 25 years. The percentage of MPS ossification was calculated using the suture obliteration index calculated on axial cross-sectional images. Statistical analysis was performed utilizing the student t-test with a significance level set at 0.05.
Results: No significant difference was found between occlusal radiographs and CBCT scans in the assessment of MPS ossification in the anterior part (P>0.05). However, significant differences existed in the suture obliteration index in anterior part (P=0.031) and posterior part (P=0.035), with higher mean values obtained by occlusal radiographs. In contrast, significant differences favoring CBCT were found in the anterior part (P<0.001) with higher mean values; no significant difference was found in the posterior part. Lastly, significant difference did not exist in the posterior part between the two imaging modalities (P>0.05).
Conclusion: For MPS assessment, both CBCT and occlusal radiography can provide predictable results. However, it is notable that CBCT still has an upper hand in providing better and more accurate results.

Aim: The present study tried to find the proper bonding and debonding technique to preserve the natural enamel surface and avoid its discoloration.Methods: Sixty newly extracted human premolars were randomly divided into three groups, and three orthodontic adhesives were applied to bond the brackets: chemically cured System 1 Plus adhesive (Ormco, USA) (CC), light-cured resin (Transbond XT, 3Munitek, USA) (LC), and resin-modified glass ionomer cement (Fuji Japan) (GI). The specimens were immersed in black tea for one week and debonded, and four prophylactic methods were applied to remove residual resin: 1) tungsten carbide bur (TC), 2) tungsten carbide bur + Sof-Lex polisher (TC + SL), 3) tungsten carbide bur + One Gloss Polisher (TC + OG), and 4) tungsten carbide bur + Po-Go polisher (TC + PG). The enamel color was measured according to the CIE standard system (Commission Internationale de l’Eclairage) by Konica Minolta CS Spectroradiometer equipment twice: 1) natural enamel color before bonding and 2) after bonding, staining, debonding, and polishing. The ΔE value is the tooth discoloration, which is measured from the mean Δa*, Δb*, and ΔL* values using the following formula ΔE = [(ΔL*)2 + (Δa*)2 + (Δb*)2]1/2 for each group. Then, it was statistically analyzed using a t-test.Results and Conclusions: Regarding adhesive materials, CC adhesive showed higher discoloration than LC in all the polishing methods. The lowest discoloration was observed in GI. The highest ΔE* values were obtained using TC only, which was deemed insufficient to remove the residual adhesives. Applying TC + Sof-Lex and TC + PoGo equally enhanced the results; therefore, they were the best polishing methods.

Background: Proper education in oral and dental health behaviors and preventive orthodontics is vital for preventing dental diseases and orthodontic abnormalities. Since children spend much time in schools and in contact with their teachers, the current study aimed to assess the level of awareness about preventive orthodontics among school hygiene instructors in Sari, Iran.
Methods: Seventy-one hygiene instructors were included in this semi-experimental study with a pre-test and post-test design. The participants completed a questionnaire before any intervention. A one-day workshop about preventive orthodontics was held for the instructors, and an educational CD and pamphlet were provided for them. The participants were asked to answer the same questions after a month. Data were compared and analyzed with SPSS 22, using paired t-test and chi-squared test.
Results: The findings revealed that the training could significantly increase the level of orthodontic awareness among hygiene instructors (P<0.001). However, the participant’s level of education and years of experience was not significantly associated with their level of awareness (P>0.05).
Conclusion: Considering the importance of health education, efficient training should be provided for school hygiene instructors to increase their awareness in the field of preventive orthodontics.
