background: elastomeric chains are commonly used in orthodontics. force decay in these materials poses clinical problems. the aim of this study was to evaluate the effects of three different mouthwashes on the force decay of orthodontic chains. materials and methods: in this experimental study, elastomeric chains with two different confi gurations were divided into eight groups (two control and...

Introduction: Mouthwashes which prevent and control caries and periodontal diseases are commonly used even without professional pre‌scription. Long-term use of mouth-washes may cause softening of restorative composites and lowering the longevity of restoration. The aim of this study was evaluation of surface hardness value of a microhybride composite (Filtek Z250) after 12 hours immersion in th...

PURPOSE The purpose of this study was to analyze American Association of Poison Control Centers (AAPCC) reports of suspected overingestion of mouthwash by children under age 6 and examine the effect of a 1995 Consumer Product Safety Commission (CPSC) rule requiring child-resistant packaging for mouthwashes containing at least 3 g (0.11 oz) of ethanol per package. METHODS The volume of ethanol...

OBJECTIVES The commonly used Nickel-Titanium (NiTi) archwires in orthodontic treatment are often exposed to fluoride-containing mouthwashes. The aim of this in-vitro study was to evaluate and compare the corrosion resistance of three commercially available NiTi archwires exposed to 0.05 wt% and 0.2 wt% fluoride mouthwashes. MATERIALS AND METHODS Three different types of NiTi archwires, 0.016″...

OBJECTIVE The objective of this study is to systematically review the literature regarding the impact of mouthrinses on oral malodor and present evidence for the treatment effects of mouthrinses on oral malodor. MATERIAL AND METHODS PubMed-MEDLINE, the Cochrane-CENTRAL and EMBASE were searched through February 10, 2012 to identify appropriate studies. Volatile sulphur compound measurements, o...

OBJECTIVE Composites sorption and solubility can be precursors of several chemical and physical processes, which lead to deleterious effects on the polymer structure. This study evaluated the effect of mouthwashes on solubility and sorption of composite resins. MATERIALS AND METHODS Forty-two specimens of each evaluated composite (Filtek Bulk Fill Flow, Opallis Flow, Durafill VS, and Filtek Z...
