Snack consumption is associated with cardiovascular disease (CVD) risk factors in children and adolescents. The aim of this study is to investigate the association of snack consumption and carotid intima media thickness (CIMT) among overweight and obesity children and adolescents.

In this cross sectional study, a total of 339 participants, aged 6 to 13 years with the body mass index Z score ≥1 enrolled in this study. Data on anthropometric measurements, pubertal status, and CIMT were documented. Food intakes of participants were measured by a valid and reliable food frequency questionnaire (FFQ). Linear and logistic regression were estimated. 

Mean age of study participants was 9.3 years and with 68.4% of obesity. After controlling for confounders, including age, sex, energy intake, puberty status, physical activity, and body mass index, one SD increase in intake of nuts decreased the CIMT, by 0.126 mm (P value=0.019). Moreover, participants in the last tertile of nuts intake had 63% lower risk of high CIMT in comparison with those who consumed less than 1.74 serving/wk of nuts (P for trend=0.006). When nuts intake was replaced by the sweet unhealthy snacks the CIMT decreased by 0.15 mm.

Our findings emphasize the positive impact of nuts consumption as a healthy snack on subclinical stages atherosclerosis. Clinical trial studies could examine the effect of different kinds of nuts consumption on CIMT and complications of CVD risk factors.

Dental amalgam is regarded as a popular restorative material. The purpose of this study is to investigate the reasons of replacing amalgam restorations in patients referring to Babol dental school within 2013-2014. In this analytic-descriptive study, age, sex, type of occlusion DMF, existence of parafunction, as well as type of tooth, restoration class and reason of amalgam restoration replacement were recorded in patients referred to the Babol dental school during 2013-2014. Furthermore, the study data were analyzed using descriptive statistical analysis. Within 263 patients, there were 81(30.8%) men and 182(69.2%) women. Most patients aged 30-40(42.2%), and were reported to suffer from class Ι dental occlusion(92.4%).The mean DMF was 9.7±2.4. Lower molars were demonstrated as the most frequent teeth group for replacing amalgam restorations as well as causing secondary caries. Furthermore, secondary caries involved the major causes of amalgam restoration replacement. The most prevalent class for amalgam restoration replacement was class II restorations. It should be noted that secondary caries were most prevalent within class II MO / DO(25 cases(44.6%)). The study findings revealed that the most common cause of the restoration replacement involved the secondary caries which was most observed in the Class II restorations.
