In the present study, the compositional changes and knoop hardness of the cavity floor prepared by Er,Cr:YSGG laser irradiation was compared with that of the conventional bur cavity. Fifteen laser and 15 bur cavities were cross-sectioned, and subjected to atomic analysis by SEM-EDX and knoop hardness test. Statistical analyses were performed using the Mann-Whitney U-test; a value of P < 0.01 wa...

introduction: in recent years, significant developments have been taking place in caries removal and cavity preparation using laser in dentistry. as laser use is considered for cavity preparation, it is necessary to determine the quality of restoration margins. glass ionomer cements have great applications for conservative restoration in the pediatric field. the purpose of this in vitro study w...

OBJECTIVE To evaluate the fracture resistance of teeth restored using 2 intracoronal direct and indirect adhesive techniques. METHODS Forty maxillary premolars were divided randomly into 4 groups of 10: group 1, intact teeth; group 2, mesio-occlusodistal (MOD) cavity preparation associated with endodontic therapy (unrestored); group 3, MOD cavity preparation and restoration with direct compos...

Macintyre, Marker and Van den Dries [6] use model theory to show that globally subanalytic functions are piecewise given by terms in a certain language. Adding symbols for the exponential and logarithm function to this language, they also show that functions definable from exponentiation and globally subanalytic functions are piecewise given by terms. This piecewise definability by terms inspir...

today laser has a lot of usage in medicine and dentistry. in the field of dentistry, laser is used in soft tissue surgery, sterilization of canals (in root canal therapy) and in restorative dentistry laser is used for cavity preparation, caries removal, sealing the grooves (in preventive dentistry), etching enamel and dentin, composite polymerization and removal of tooth sensitivity. the use of...

Aim: To investigate the longevity of ceramic laminates with minimally invasive preparations. Materials and methods: The research was conducted in PubMed, Web of Science, and Scopus databases, using the keywords “dental veneers” or “dental porcelain” or “dental laminates” and survival or survivorship or longevity or “follow-up studies” and Kaplan-Meier. The studies selected for analysis were cli...

BACKGROUND AND OBJECTIVES The aim of the study was to determine the effect of two access cavity designs on the peri-cervical dentin thickness before and after instrumentation using cone beam computed tomography (CBCT). MATERIALS AND METHODS Sixty mandibular anterior teeth were divided into two groups of thirty teeth each: Group I: conventional access cavity preparation, where access was prepa...

In this era of minimal intervention dentistry, the changing concept of cavity preparation and the introduction of reliable adhesive materials have lead to the development of alternative methods of caries removal. Chemo mechanical caries removal (CMCR) involves the chemical softening of the carious dentine, followed by its removal with gentle excavation. This process removes only the infected ti...
