Abstract
Background and purpose: The prevalence of maxillary missing lateral incisor (MMLI) is 1-2% which is responsible for 20% of all missing teeth. Increased knowledge about causes and clinical manifestations of cases with this situation can be helpful for diagnosis and treatment planning. The aim of the present study was to determine dental and skeletal features of patients with missing maxillary lateral incisors.
Materials and methods: The material consisted of pre-treatment dental casts and cephalograms of 26 patients with unilateral or bilateral MMLI. The following parameters were measured on dental casts: the maxillary and mandibular intercanine width (ICW) and intermolar width (IMW), overjet, overbite, missing or anomalous of other teeth. Parameters that were measured on cephalogram included: SNA, SNB and ANB angle and Wits. The parameters were finally compared to a control group with normal occlusion using paired t-test.
Results: Eight subjects with MMLI had bilateral missing and in 18 subjects with unilateral missing, 66.67% (n=12) had lateral missing on the right side. MMLI was associated with other anomalies or congenital tooth absence in 12 subjects. The overject was significantly lower compared to that in the control group (P=0.05) and upper and lower ICW were smaller. Both ANB angle and Wits significantly decreased in this group (P=0.05).
Conclusion: Absence of maxillary lateral incisor was highly correlated with other tooth anomalies. Most of patients with this situation had skeletal and dental Class III tendency.

Abstract
Relapse is an unpredictable risk factor for every patient. Before treatment begins, patients need to be informed of the long-term risk of relapse and the ways that this may be reduced. Some causes of relapse are within the control of the orthodontist, but others such as soft tissue changes and latent growth are not, and may explain long-term changes in tooth position. Therefore, retention after orthodontic treatment has been recommended by several authors and orthodontists. The objective of the retention phase is to maintain teeth in their corrected position after orthodontic treatment. This article aimed to review the causes of relapse and the ways that reduce it using retainers and other new adjective techniques.

Abstract
Background and purpose: Malocclusion is the most prevalent dental anomaly that influences the function of affected people. As a common orthodontic index, the Index of Orthodontic Treatment Needs (IOTN) classifies the malocclusions according to occlusal indexes of an individual. This research aimed at evaluating the need for orthodontic treatment in students aged 12-14 years old in Sari using IOTN Index in academic year 2016-2017.
Materials and methods: In this descriptive cross-sectional study, the IOTN was used for 576 students in six different schools. The IOTN index includes two components which are closely related; in current study, only the dental health component (DHC) was assessed. Data analysis was done in SPSS V21 applying Chi-square.
Results: A total of 576 students was studied of whom most (29.2%) were in grade 2, which showed little need for treatment (30% males and 28% females). Only 2.8% were graded as 5 on the IOTN scale meaning serious need for orthodontic treatment. Male and female students were homogeneous in grading distribution and there was no significant difference between the two groups (P< 0.75). The frequency of need for orthodontic treatment was 25.35%.
Conclusion: In this study, most of the individuals showed little need of orthodontic treatment and there was no significant difference between the two groups in grading distribution.

Abstract
Background and purpose: A pandemic can negatively affect both mental and social health. The aim of this study was to evaluate stress, anxiety, and sleep disorders experienced by dentists during COVID-19 pandemic.
Materials and methods: This cross-sectional descriptive study was conducted on all dentists in Sari (290 dentists). Corona Disease Anxiety Scale and Pittsburgh Sleep Quality Index were used as questionnaires. Data analysis was conducted using SPSS V26.
Results: A total of 126 dentists completed the questionnaires. The mean values of stress and anxiety score for general dentists and specialists were 12.4 and 11.5, respectively which were classified as mild level. There was no statistically significant relationship between sex, anxiety, and stress (P=0.09 for general dentists; P=0.13 for specialists). The prevalence of sleep disorders was 78% and 72% for general dentists and specialists, respectively. The mean value of sleep disorders was 6.8 for general dentists and 6.1 for specialists which was considered as low and inappropriate. There was no statistically significant relationship between sleep disorders and sex (P=0.4 for general dentists; P=0.9 for specialists).
Conclusion: The dentists' stress and anxiety level was mild during the COVID-19 pandemic. Prevalence of sleep disorders was high and sleep quality was poor and unsuitable for both general dentists and specialists.
