Secondary caries has been reported as the main reason for restoration replacement. The aim of this in vitro study was to evaluate the performance of different methods--visual inspection, laser fluorescence (DIAGNOdent), radiography and tactile examination--for secondary caries detection in primary molars restored with amalgam. Fifty-four primary molars were photographed and 73 suspect sites adj...
خلاصه: سابقه و هدف: با توجه به اینکه دیاگنودنت وسیلهای برای تشخیص پوسیدگیهای دندانی و قابل مقایسه با روش های رادیوگرافی و دیداری است، تغییر در فلورسنت مواد ترمیمی، می تواند در تشخیص پوسیدگی توسط دیاگنودنت اختلال ایجاد کند. هدف این مطالعه بررسی تاثیر Staining، Aging وBleaching بر نتایج دیاگنودنت در ترمیم های کامپوزیت بود.مواد و روشها: تحقیق از نوع تجربی بود و 6 نوع کامپوزیت مختلف شامل Tetr...
AIM The aim of this systematic review was to assess the in vivo scientific evidence regarding the ability of a recently developed light fluorescence device, SoproLife® (Sopro-Acteon group, La Ciotat, France) in detecting occlusal carious lesions. The PubMed database was searched for in vivo trials that evaluated the validity of the SoproLife® camera for the detection of occlusal carious lesions...
OBJECTIVE This study aimed to evaluate in vivo the occurrence of secondary caries and dentin characteristics in permanent molars after traditional amalgam restorations, by means of clinical visual examination, radiographs and laser-induced fluorescence (LF) (DIAGNOdent). METHODS Thirty first permanent molars of 30 schoolchildren in the 7 to14 year-old age group were included. Caries was remov...
BACKGROUND Chemomechanical caries removal system is part of the minimal invasive dentistry; the aim of the study was to compare the amount of bacteria after caries removal with chemomechanical system and conventional rotatory instruments and to test the Vickers microhardness and micro-RAMAN analysis of residual dentin after excavation. MATERIALS AND METHODS Molars were induced for demineraliz...
Non-intrusive, non-contacting frequency-domain photothermal radiometry (FD-PTR or PTR) and frequency-domain luminescence (FD-LUM or LUM) have been used with 659- and 830-nm laser sources to assess the pits and fissures on the occlusal surfaces of human teeth. Fifty-two human teeth were examined with simultaneous measurements of PTR and LUM and were compared to conventional diagnostic methods in...
OBJECTIVES The aim of this study was to evaluate the efficiency of ozone alone and with a re-mineralizing solution following application on initial pit and fissure caries lesions in permanent molars. METHODS Forty children (9-12 years) having non-cavitated fissure caries lesions on bilateral 40 first permanent mandibular molar teeth were participated in the study. Patients were randomly alloc...
The purpose of this manuscript is to discuss the current available methods to detect early lesions amenable to prevention. The current evidenced-based caries understanding, based on biological concepts, involves new approaches in caries detection, assessment, and management that should include non-cavitated lesions. Even though the importance of management of non-cavitated (NC) lesions has been...
