The prevalence of dental caries and supragingival plaque and calculus in 785 secondary schools students was assessed. More than half (53.6%) of the students were caries-free, and the majority of those with dental caries experience were aged 14-17 (68.1%) and females (53%). Mean DMFT was 1.26, with mean D-component of 1.05, and molars were most affected. Most students had supragingival plaque (7...

Caries lesion progression is highly dynamic process characterized by alternating periods of dissolution and redeposition of minerals in the dental hard tissue. When outcome of these processes overtime is a net loss of mineral, a caries lesion develops or progresses. However, when redeposition of mineral predominates, the result may be arrest of lesion progression or remineral ization. Clinical ...

Diet plays an important role in preventing oral diseases including dental caries, dental erosion, developmental defects, oral mucosal diseases and, to a lesser extent, periodontal disease. This paper is intended to provide an overview of the evidence for an association between diet, nutrition and oral diseases and to clarify areas of uncertainty. Undernutrition increases the severity of oral mu...

The combined benefits of pit and fissure sealants and weekly mouthrinsing with a 0.2% neutral NaF solution were assessed in children who initially had no caries or restorations in their permanent teeth. Ninety-five children participating in a school-based weekly fluoride mouthrinsing program since kindergarten had sealants applied to their first permanent molars when they were in the second and...

BACKGROUND The prevalence of early childhood caries (ECC) among children in Beijing, China, has been increasing continuously though slowly. However, there is limited information about ECC in Beijing. The aim of this study was to identify risk factors of dental caries among preschool children in Beijing. METHODS For this case-control study, using a convenience sampling method, 787 children age...

Objectives Oral health is a major component of overall health improvement and well-being. A large number of children are suffering from Early Childhood Caries (ECC). Parental knowledge and level of education can improve their child’s oral health care leading to reduction of ECC incidence. The aim of this study was to evaluate the level of education and knowledge in a group of parents, having th...

BACKGROUND AND AIM: Dental caries is a multifactorial disease that affects people of any age, sex, and race. Significant caries index (SiC index) has been defined by World Health Organization (WHO) to evaluate caries status in different societies. The aim of this study was to determine the SiC index in 15-year-old children in Kerman. METHODS: This descriptive cross-sectional study was carried o...

The aim of this study was to examine the colonization of Streptococcus mutans and Streptococcus sanguinis in the oral cavity and the association with severe early childhood caries (S-ECC). Saliva and plaque samples were collected from 14 S-ECC children and 8 caries-free (CF) children. All S-ECC children were S. mutans positive; 100% of CF children and 93% of S-ECC children were S. sanguinis pos...
