The purpose of this study is to compare the marginal leakage of two aesthetic cervical restorative materials viz the newly introduced light cured nano glass ionomer cement and nano ceramic composites, and also to evaluate the effect of unfilled resin sealant coating on marginal leakage of these aesthetic restorations. Thirty freshly extracted human upper premolars were used for the study. Class...

Restorative dentistry and periodontal health are closly related. Changes which occur in the periodontal tissues during and after restorative treatments of dental caries can be expected not only on theo retical grounds but also can be observed in the daily routine practice. Various experiments have been made concerning the character of these changes. A series of animal experiments concerning the...

This study investigated the effect of silver diamine fluoride (SDF) and potassium iodide (KI) treatment on secondary caries prevention and tooth discolouration in glass ionomer cement (GIC) restoration. Cervical GIC restorations were done on 30 premolars with: Group 1, SDF + KI; Group 2, SDF (positive control); Group 3, no treatment (negative control). After cariogenic biofilm challenge, the de...

51 isolation through the dental dam) and 2) a biological parameter (depending on the biologic width). Three different clinical situations and three different therapeutic approaches are identified (1 st , 2 nd , and 3 rd , respectively): coronal relocation of the margin , surgical exposure of the margin, and clinical crown lengthening. The latter is associated with three further operative sequen...

Dental materials have been continuously developing over a long period of time. Every effort has been made to develop the physical and mechanical properties of the materials to mimic the natural tooth substances. However, that has not yet been achieved, making it necessary to apply conservative dental treatments. Conservative treatments are procedures which minimize the amount of defective tooth...

STATEMENT OF PROBLEM Little information is available about the buccal gingival level of multiple implant restorations. PURPOSE This study was aimed to evaluate the relationship between width and height of buccal soft tissue around single and 2 adjacent implant restorations. MATERIAL AND METHODS Four implant restoration groups (first and second molars, single second molars, posterior single ...

The purpose of this study was to evaluate gap formations under class V restoration using swept-source optical coherence tomography (SS-OCT). Wedge-shaped cavities were prepared on the buccal surface of 40 extracted premolar teeth at 2 locations; 1) cemento-enamel junction (CEJ) with enamel and cementum margin and 2) root surfaces with cementum margin. The cavity was treated with Clearfil S(3) B...

UNLABELLED Noncarious cervical lesions are highly prevalent and may have different etiologies. Regardless of their origin, be it acid erosion, abrasion, or abfraction, restoring these lesions can pose clinical challenges, including access to the lesion, field control, material placement and handling, marginal finishing, patient discomfort, and chair time. This paper describes a novel technique ...

BACKGROUND Different CAD/CAM machines' generation may impact the restoration overall quality. The present study evaluated the marginal fit of CAD/CAM restorations manufactured with different generations of CEREC milling unit systems. MATERIAL AND METHODS Sixteen typodont teeth were divided into two groups (n=8) according to the machine's generation assigned. These are control group (G1): Cere...

INTRODUCTION The success of bonded restorations depends on effective bonding between restorative materials and tooth structure, and it prevents microleakage. New dentin bonding systems have been introduced which promotes this concept. The aim of this study was to compare the amount of microleakage between 'single bond' vs 'Prompt L-Pop' during different time periods. MATERIALS AND METHODS In ...
