Effect of Proarginine Technology Plus 1450 PPM Fluoride on Enamel Reminerlization: An in Vitro Study
AIM: The objective of this in vitro study was to evaluate the effects of new dentifrices containing 1.5% arginine, an insoluble calcium compound, and fluoride for their ability to promote remineralization of demineralized enamel. Methods: Twenty human premolar extracted for orthodontic reasons were used. The specimens were immersed in demineralization solution followed by application of proargi...
Background and purpose: Deep fissures of occlusal surface in recently erupted first permanent molars are prone to accumulation of bacterial plaque. Sealing these fissures by appropriate flowing materials, as pit and fissure sealants, is a conservative way to prevent caries. The purpose of this study was to compare retention of flowable composite resin by resin modified glass ionomer sealant in ...
objectives: this study aimed to compare the incidence of white spot lesions (wsls) around orthodontic bands following the application of two glass ionomer (gi) cements namely gc gold label and gc fuji plus for six to 12 months. materials and methods: a total of 186 permanent first molars of orthodontic patients requiring banding of at least two permanent first molars were chosen. the teeth were...
background: direct observation cannot detect caries under restorations; therefore, the aim of this study was to compare the accuracy of radiographs and diagnodent in detecting caries under restorations in primary teeth using histologic evaluation. materials and methods: a total of 74 previously extracted primary molars (37 with occlusal caries and 37 without caries) were used. class 1 cavity pr...
UNLABELLED There are several methods for identifying carious dentinal tissue aiming to avoid removal of healthy dentinal tissue. OBJECTIVES The purpose of this study was to test different methods for the detection of carious dentinal tissue regarding the amount of carious tissue removed and the remaining dentin microhardness after caries removal. MATERIAL AND METHODS The dentin surfaces of ...
OBJECTIVES The aim of this study is to determine the effects on remineralization of a novel iontophoresis device called 'Fluorinex', conventional (acidulated phosphat fluoride) APF gel treatment, and conventional ionthophoresis device comparatively by laser fluorescence measurements. STUDY DESIGN Artificial incipient carious lesions were created on immature, 60 intact premolar and molar teeth...

the aim of this study was to compare the level of agreement between four operators with different levels of experience for two methods of detecting secondary enamel and dentin carious lesions in composite restored teeth.sixty teeth of 40 patients with with secondary carious lesions in the composite resin were selected. the teeth were examined by two methods; visual inspection and a laser fluore...
This epidemiological study aimed to compare the diagnostic outcome of the WHO criteria, ICDAS II criteria, laser fluorescence measurements, presence of plaque and roughness as activity scores on occlusal fissures and buccal/palatal pits of the first permanent molars. The study involved 311 children between 8 and 12 years of age from the Ennepe-Ruhr District in North Rhine-Westphalia, Germany. T...
مقدمه: تشخیص نیاز نواحی معدنیزدایی شده پروگزیمالی به تهیه حفره و ترمیم، همواره به عنوان یک موضوع چالش برانگیز در طرح درمانهای ترمیمی مطرح بوده است. هدف از این مطالعه بررسی کارایی روش لیزر فلورسانس (lf) در تشخیص حفرات پروگزیمالی بود. مواد و روشها: در این مطالعه بالینی، تعداد 44 سطح پروگزیمالی در 38 دانشجوی دندانپزشکی مورد بررسی قرار گرفت. بیمارانی انتخاب شدند که در رادیوگرافی بایت وینگ دارای ...
