Abstract
Background and Objective: Due to increasing of child and youth patients that require orthodontic treatment procedures, finding the person with normal occlusion and cephalometric analysis can be valuable. The aim of this study was to investigate the indicators and cephalometric parameters of Babol youths with normal occlusion. Methods: In this analytical and cross-sectional study, 34 male students between 12-18 years with mean age of 15 and with CLI connection, suitable overjet and overbite, without crowding and spacing and suitable profile were selected among 1200 students of Babol. After taking their parents consent, lateral cephalometry from them was performed in similar condition. After necessary analyses (Down, Tweed and Steiner), they were compared with Caucasian race patterns. Findings: After tracing and cephalometric analysis of each sample, these findings were obtained totally: Facial plane angle 82.41°, angle of convexity 4.78°, A-B plane to N-pog -4.67°, mandibular plane to Frankfort (FMA) 28.06°, y-axis to Frankfort 65.50°, occlusal plane to Frankfort 12.60°, interincisal angle 124.74°, lower incisor to occlusal plane 25.66°, lower incisor to mandibular plane (IMPA) 100.69°, lower incisor to Frankfort (FMIA) 51.89°, lower incisor to mandibular plane (Tweed analysis) 100.69°, SNA 80.63°, SNB 77.93°, ANB 2.71°, mandibular plane to SN 31.97°, occlusal plane to SN 16.81°, upper incisor to N-A 22.82°, lower incisor to NB 30.44°, upper incisor to AP 8.53mm, upper incisor to NA 7mm, lower incisor to NB 7.13mm. Conclusion: According to the results, facial and interincisal angle compared to white European race samples had lower average. But, angle of convexity, FMA, y-axis and occlusal plane to Frankfort angle, lower incisor to occlusal plane angle, IMPA, lower incisor to NB angle, lower incisor to NB (mm) were higher while angles of AB to N-pog, SNA, SNB, ANB, mandibular plane to SN, occlusal plane to SN, upper incisor to NB (mm), do not show considerable difference with white race in this study.

Abstract
BACKGROUND AND OBJECTIVE: Proportional relationship between different facial structures, including soft tissue thickness and dental and skeletal components, is the key to beauty. Today facial soft tissue harmony is the primary goal of orthodontic treatment, unlike the past which focused only on hard tissue and dental occlusion. The aim of this study was to measure facial soft tissue thickness in the northern population of Iran with class I skeletal pattern in lateral cephalometry and compare these values between males and females to use the results in orthodontic treatment and craniofacial reconstructions.
METHODS: In this cross-sectional research, 180 lateral cephalometry of 77 male and 103 female, aged between 18-24 years who had referred to private orthodontic offices, were traced on acetate paper. Then, 10 anatomical variables were measured in Glabella, Nasion, Rhinion, Subnasal, Upper lip, Stomion, Lower lip, Labiomental region, Pogonion and Menton parallel to the Frankfurt plan.
FINDINGS: Facial soft tissue thickness in males was significantly higher than females in Nasion (male=5.65±1.55, female=4.38±1.47), Rhinion (male=3.07±0.64, female=2.5±0.57), Subnasal (male=16.39±2.55, female=14.05±1.44), Upper lip (male=15.51±2.29, female=13.57±1.64), Lower lip (male=16.48±1.85, female=14.64±1.39), Labiomental (male=11.02±1.46, female=10.49±1.67) and Pogonion (male=11.4±1.64, female=10.32±1.77) (p<0.05).
CONCLUSION: Based on the results of this study, there was a significant difference in facial soft tissue thickness between the two genders in the north Iranian population so that males had more facial soft tissue thickness than females in most of the areas.

Abstract
Background and Objective: Knowledge of airway dimensions is important in the process of diagnosing and planning the treatment of orthodontic patients. Therefore, this study was conducted with the aim of performing cephalometric anlysis of airway dimensions in patients with different vertical jaw relations in the specialized clinic of Babol Dental School.
Methods: This cross-sectional study was conducted on 150 lateral cephalometric radiographs taken from patients aged 18 to 25 before orthodontic treatment. Based on the FMA angle and Jarabak index, the patients were divided into three groups of 50 according to the vertical skeletal pattern. The width of the upper (UP) and lower (LP) airways was measured in millimeters using McNamara's analysis. Moreover, the width of the nasopharynx (PNS-UPW), oropharynx (U-MPW) and hypopharynx (V-LPW) was recorded in millimeters and compared in three groups.
Findings: The studied population included 43 men and 107 women with a mean age of 20.39±2.50 years. The results showed a significant relationship in the dimensions of the upper airway, nasopharynx, and oropharynx between the vertical groups (p=0.001, p=0.001, and p=0.015, respectively). All these parameters in the Hyperdivergent group were significantly lower than the other two groups, and no significant relationship was found between the Hypodivergent and Normodivergent groups. The mean upper airway in Normodivergent group was 13.62±3.05. In addition, the dimensions of the lower airway and hypopharynx were not significantly different between the vertical groups.
Conclusion: The results of the study showed that hyperdivergent patients have a narrower upper airway. However, lower airway dimensions are not affected by vertical growth pattern factors.
