Aim: The aim of this study is to determine the factors affecting mouth breathing syndrome in children and to evaluate the relationship between these factors. Materials and Methods: In this study, 120 healthy children aged 6-14 years who applied to Istanbul University Faculty of Dentistry, Department of Pedodontics between October 2019 and April 2020, with 60 mouth breathing and 60 nasal breathing. Individuals who agreed to participate in the study were provided with a complete answer to the questionnaire which consist of 20 questions, divided into 4 factors, and their dmf and DMF values were recorded by performing an intraoral examination. Student's t test, Mann Whitney U test and Shapiro Wilks test were used for analyzes Results: The dmf values of children with mouth breathing were significantly higher than those with nasal breathing (p

Although a decrease in the prevalence of dental caries, which is a chronic disease, has been reported in many developed countries, early childhood caries (ECC) as an early childhood disease is common, especially in developing countries. 'Silver diamine fluoride' (SDF) stops dental caries, prevents the formation of dental caries and reduces tooth sensitivity. The biggest feature that distinguishes SDF from other fluoride agents that prevent caries formation is that it effectively stops the caries process. This effect is provided by the synergistic effect of silver ions and fluoride. As a result of clinical studies, the use of SDF at the rate of 38% is recommended for the most effective result. SDF is becoming more popular as a practical and affordable treatment option to stop caries. SDF, especially during the pandemic period when minimal aerosol production is important; can be routinely experienced in a pediatric dental office in a variety of clinical scenarios for both primary and permanent teeth. It can be used effectively and efficiently in different behavior patterns of children and in different age groups. In this review, the effect mechanism, usage areas, clinical uses and results of SDF will be evaluated in the light of current literatures.
