Abstract Background The choice between extraction and expansion treatment is an endless debate in orthodontics. Ethnic and secular variations showed that there was a change in  arch perimeter over the last 50 years. Accordingly, the purpose of this study was to investigate the relation between the arch perimeter and the intercanine and intermolar widths in normal occlusion. Also, to design regression equations for the prediction of the arch perimeter based on arch width, in a sample of the Egyptian population. The images of 340 cast pairs for 11 to 13-year-old patients were traced using TracerNet. Intercanine width, intermolar width and arch perimeter were measured, statistical analysis was performed and regression equations for both arches were formulated. Results There was a positive correlation between the lower arch AP, ICW and IMW and between the upper arch AP and ICW. Lower arch perimeter = 0.536 I33 + 71.642, lower arch perimeter = 0.828 l66 + 58.604 and upper arch perimeter = 1.988 U33 + 30.492 were the significant derived equations. Conclusions The formulation of regression equations offers a tool for the prediction of arch perimeter or arch width that can act as a guide in diagnosis and treatment planning.

The current study aimed to find a prediction equation to estimate the arch perimeter (AP) depending on various arch dimensions including intercanine width (ICW), intermolar width (IMW), interpremolar width (IPMW), and arch length (AL) in a sample of the Kurdish population in Sulaimani City. The study sample was 100 pairs of preorthodontic dental casts. Calculations of dental arch dimensions and perimeter were performed by a digital vernier. Statistical analysis was performed via using the SPSS version 25 software. The developed prediction equation for the upper arch was Y = + 1.3 × arch   length + 1 × intermolar   width , whereas the equation for the lower arch was Y = + 0.9 × intermolar   width + 0.92 × intercanine   width . Paired t -test revealed no statistical difference between predicted and real arch perimeters. Two separate prediction equations for upper and lower arches were developed based on the arch length (AL) and intermolar width (IMW) for the maxillary arch, intermolar (IMW), and inter canine widths (ICW) for the lower arch. The developed equations could have further beneficial impacts on orthodontic diagnosis and treatment planning.

Introduction: The Invisalign system has been used in the orthodontic treatment of numerous types of malocclusions. However some clinicians have reported difficulty incorrecting rotations particularly in canines and premolars using the Invisalign appliance system. This case report describes the orthodontic treatment of an adult patient with severe canine rotation (more than 45°) and crowding on upper and lower tooth.Methods: The clinical examination included extra-oral and intra-oral photographs, panoramic radiographic, lateral cephalometric, stone casts, and upper and lower arch analysis obtained from ClinCheck 3.0.The treatment planning was resolved the crowding in both upper and lower arches and the severe rotation of 33 tooth (46°) using Invisalign system as well as the canine and molar relationship, dental verticalization, adequate over jet, overbite and dental midline using the same system. The duration of the treatment was approximately eight months.Results: In Post-treatment extra oralphotographs, no significant changes were observed at the end of the treatment. Intraoral photographs showed an important and notable improved aesthetics. The canine relationship improved slightly and molar Class Irelationship was maintained. An increase in transverse diameter was observed at the level of first premolars, second premolars and first molars. The overbite was improved. The crowding and the severe canine rotation were corrected. No obvious root resorption was radiographically evident and slight cephalometric changes.Conclusion: The treatment with the Invisalign system resolved the complaint of our patient so this system could be considered as an option that offered good results in the treatment of upper and lower crowding of arches involving severe canine rotation.

Abstract. This article concerns the utility of ego psychoanalytic perspectives in Rorschach interpretation. Psychoanalytic ego psychology focuses on how people cope with events in their lives and how effectively they can meet challenges to their sense of well-being. The way people deal with experienced distress constitutes their defensive style and determines to a large extent what kind of person they are. Adequate defenses against anxiety promote comfortable and productive adjustment, whereas ineffective defenses typically cause adjustment difficulties and susceptibility to psychological disorders. In Rorschach assessment, the nature and effectiveness of a person’s defensive style can often be identified with a sequence analysis that integrates the structural, thematic, and behavioral features in the protocol. In particular, the sequential quality of responses, especially preceding and following instances of cognitive slippage, can help identify causes of upsetting concerns, defensive efforts to alleviating these concerns, and the adequacy of these defensive efforts in restoring equanimity. This interpretive process is illustrated with attention to implications for differential diagnosis and treatment planning in the Rorschach protocol of a 20-year-old suicidal woman.
