Introduction: Soft tissue has a prominent role in diagnosis and treatment plan in orthodontics. Facial proportions are measurable on lateral cephalograms. The purpose of this study was to compare the means of the normal soft tissue proportions of babol people with the norms of Caucasians.
Materials & Methods: In this cross-sectional study, 100 cases with normal occlusion and proportional facial profile were participated from babol. After taking radiographs and tracing, the soft tissue variables were analyzed to find means and standard deviations. The data were compared with Caucasian's norms using T-test.
Results: The norms of following variables in babol people were significantly different from those of Caucasians: facial convexity, nasolabial angle, upper lip thickness, chin soft tissue thickness and protrusion of lower lip.
Conclusion: In babol, people have a more convex profile, more prominent nose and lower lip than caucasians.

Introduction: Ability to reconstruct the papilla in anterior maxilla is important aspect of perio-plastic surgery. In most articles, connective tissue is used with different designs of incisions. The aim of this study was to use sub-epithelial connective tissue graft (SCTG) with two types of incisions called papilla preservation and semilunar.
Materials & Methods: This basic randomized clinical study was performed on 10 sites in two patients. The patients were selected through inclusion and exclusion criteria.  Papilla preservation and semilunar techniques were performed on four and six sites, respectively in the anterior maxilla. In both techniques SCTG was  gained from palate .The apico-coronal and mesiodistal changes of the dark triangles were measured after 3 and 6 months. Landry(Healing) index was measured after 14 days and one month,Visual Analogue Scale (Esthetic) index was estimated in 3 and 6 month after surgery and Visual Analogue Scale (VAS ) index was  analysed as well . Data were analysed using SPSS. Mann- Whitney, Wilcoxon and Paired t- Test were measured.
Results: Mean±SD of mesiodistal distance in the time of surgery was 2.00±0.000 in semilunar and 2.1±0.629 in papilla preservation technique whereas after 3 months, it was 1.33±0.016 and 1.37±0.478 for semilunar and papilla preservation, respectively and after 6 month was 1.00±0.000 for semilunar and 1.25±0.500 for papilla preservation. Mean±SD of apicocornal changes by semilunar incision in the time of surgery ,3 month after and 6 months later was 2.67±0.516 ,2.25±0.612and1.91±0.204 whereas by papilla preservation was 2.50±0.577,2.25±0.500 and 2±0.000, respectively.
Conclusion: Both techniques had positive effect on papilla reconstruction and the outcome was the same in both groups.

Introduction: Healthy primary teeth are necessary for a child's physical and mental health. Increasing mothers’ awareness of the importance of these teeth is significant for the creation of healthy teeth in their children's mouths. Thus, the aim of this study was to evaluate mothers’ awareness of the importance and care of their children’s primary teeth in Yasuj
Materials & Methods: In this cross-sectional study, 384 mothers with their children aged ≤6 years were enrolled. The data were collected via a 12-item researcher-made questionnaire and analyzed using mean, standard deviation, Spearman and binary logistic regression tests.
Results: The mean age of mothers was 29.71±5.04 years. The mean score of mothers’ awareness of the importance of primary teeth was 5.9±2.76 ) score of  0-12).No mothers had good awareness, 119 (31%) and 265 (69%) mothers had moderate and poor awareness in this regard, respectively. A significant relationship was found between mothers’ age and awareness (p=0.0001, r=0.18) as well as between parental education level and awareness (p=0.0001, r=0.25). Parental education levels including subdiploma P=0.009, EXP (B)=15.19, 0.95% CI= 1.97-116.91; diploma and technician P=0.0001, EXP (B)=39.42, 0.95% CI= 5.03-308.81; Bachelor’s degree P=0.001, EXP (B)=27.02, 0.95% CI= 3.55-205.73; Master’s degree and higher P=0.003, EXP (B)=26.26, 0.95% CI= 2.95-233.26 as well as maternal age P=0.008, EXP (B)=1.07, 0.95% CI= 1.02-1.14  were predicting factors for mothers’ awareness of the importance and care of the primary teeth.
Conclusion: Considering the undesirable level of mothers’ awareness of the importance and health, the interventions  and planning are essential to enhance mothers’ awareness in this regard.
