Introduction: Orthodontics is defined as a branch of dentistry that deals with the correction of malocclusion. In this regard, determining the most appropriate time for orthodontic treatment is of utmost importance. General dental practitioners (GDPs) are normally the first link of the treatment chain of patients needing orthodontic treatments. The present study aimed to determine the GDPs’ knowledge of appropriate timing of orthodontic treatments in Sari, Iran. Material and methods: This descriptive, analytical and cross-sectional study was performed on GDPs working in Sari in 2019. The statistical population included 380 GDPs, 186 of whom were selected. Data were collected using a 24-item questionnaire is applied to evaluate the GDPs’ knowledge level of the appropriate timing of orthodontic treatments. Data analysis was performed in SPSS version 19.Results: In total, 142 out of 186 GDPs participated in the study with a mean age of 36.12±10.15 years. 86 subjects (59.9%) had less than 10 years of work experience. Total mean (±SD) knowledge level of the GDPs was estimated at a moderate level (14.13±3.79). Percentage of the knowledge levels of poor, moderate and good was 12, 70, and 18, respectively. There was significant relationship between knowledge level and gender (P=0.013). Meanwhile, no association was observed between the work experience of the participants and their level of knowledge (P=0.393).
Conclusions: According to the results of the present study, the total mean score of GDPs’ knowledge of appropriate timing of orthodontic treatments in Sari was moderate, and only 12% of the participants had poor knowledge level in this regard. It is notable that male subjects had a significantly higher knowledge level, and another analysis demonstrated the lack of effectiveness of work experience on the knowledge level of individuals.

Context: In recent years, lasers have numerous applications in orthodontics as an important field of dentistry. The purpose of this article is to review some of the major applications of laser in the field of soft tissue management in orthodontics.
Evidence Acquisition: No single laser wavelength can be used to optimally treat all dental diseases. However, the needs of the orthodontic clinician are unique and selection of the most appropriate laser for orthodontic applications is essential to achieve optimal results. Results: Light emitted from diode lasers is poorly absorbed by dental hard tissues, these lasers can be safely used for soft tissue surgery applications, including gingival recontouring, crown lengthening, removal of hypertrophic tissue and frenectomies close to the enamel, dentine and cement. Considering beam safety, most of the lasers used for medical and dental purposes are in the Class IV category, so it is necessary to take appropriate safety measures.
Conclusions: In the near future, with the clarification of laser exposure protocols and a decrease in device cost and, Dental lasers may play an increasingly important role in soft tissue management during orthodontic treatment.

Background: Maxillary molar distalization with intraoral or extraoral appliances is a common treatment modality in non-extraction treatment plan.
Objectives: In this study, an appliance with hyrax screw was used for maxillary molar distalization. Our purpose was to evaluate the amount of molar distalization, type of molar movement, effects on anterior teeth, and amount of changes in lower anterior facial height.
Patients and Methods: 24 class II patients (13 females, 11 males) with bilateral half cusp class II molar relationship were participated. The appliance was made by hyrax screw for producing distalization force. Pre and post distalization lateral cephalometric radiographs and dental casts were evaluated. Lateral cephalograms and study models were obtained before treatment and after 12 weeks activation of the appliance (one turn per week).
Results: Cephalometric measurement demonstrated that, first molars tipped 2.9 degrees and displaced 1.76 mm. First premolar and upper incisor tipped 3.4 and 4.2 degrees, displaced 2.9 and 2.4 mm respectively. All of these results were statistically significant. The mean of maxillary first molars distaliztion was 2.6 mm per side in approximately four month. The mean of first maxillary molars tip was 3.93˚ and the mean of anchorage loss at the first premolars was 1.95 mm, but the crowns tipped 3.45˚ mesially. Lower anterior facial height (ANS-GN) and mandibular plan angle (GO-GN) increased, 0.7 ± 0.21 mm and 0.76 ± 0.32 degree, respectively, but were statistically insignificant.
Conclusions: It can be concluded that proposed appliance can correct class II molar relationship. Molars displaced distally by bodily movement and tipping.

Patients with midline or generalized diastema can be managed successfully by multidisciplinary approach. Our patient was managed by orthodontic, prosthodontic and restorative procedures. After orthodontic treatment, maxillayr labial frenectomy was done for this patient to reduce the possibility of relapse. Restorative treatments were also performed to close the remaining spaces. After all, a fixed prosthodontic bridge was constructed to close the remaining posterior space.

Aim: The objective of this study was to compare and evaluate the effects of two functional appliances including modified activator and modified twin block appliances on the profiles of facial soft tissue. Methods: This study included 30 patients suffering from skeletal class II abnormalities. Participants were randomly allocated into one of two treatment groups for functional appliances, the modified twin block group and the modified activator group (ten girls and five boys, with a mean age of 10.4± 0.82 years in the modified twin block group; nine girls and six boys, with a mean age of 9.8± 0.94 years in the modified activator group). The mean duration of treatment was 20.4± 6 months in the modified activator group, and 17.9 ± 5 months in the modified twin block group which included the eight months of aftertreatment maintenance. Data were analyzed using a paired t-test and an independent samples t-test. Results: In the modified activator treatment group, changes in the labiomental angle (p=0.02), the angle of facial convexity (p=0.004), the Ls-S vertical (p=0.034), the distance between the labial surface of the upper central incisor and the upper lip (p=0.012), the Li-E Line (p=0.029), the total anterior facial height (p=0.008) and the pog’-S vertical (p=0.013) were significant. The difference between two groups was significant only in Li-E line.
Conclusion:The effects of modified activators and modified twin block appliances on the soft tissue profile was almost the same, and both resulted in significant alterations to the soft tissue profile.
