PURPOSE To determine the 18-month clinical performance of four tooth-colored restoratives in non-carious cervical lesions. MATERIALS AND METHODS Buccal abrasion lesions in 83 teeth were restored with each of the following materials: Fuji Cap II, Fuji II LC, APH/Universal Bond 3, Lite Fil II A/Imperva Bond. Baseline and an 18-month recall was carried out(More)

The position of the mental foramen of the local Malays and Indians in Singapore was determined from a series of orthopantomograms. The most frequent location does not conform to the position cited in many anatomy, surgery, and dental anesthesia texts as being below and between the apices of the lower premolars. This data has implications in the teaching and(More)
This study investigated the status and associations of perceived chewing ability of a group of 891 elderly people, aged 55-91 years (average age 66 years). The majority of subjects (69%) considered that they could chew well. Only 9% reported poor chewing ability. This judgement was not associated with age. More men (11%) than women (6%) had reported poor(More)
The benefits of using sodium hypochlorite (NaOCl) and ethylenediaminetetraacetic acid (EDTA) as endodontic irrigants, and calcium hydroxide as an inter-appointment medicament, are well known to dentists. Many steps undertaken during endodontic treatment and retreatment are rather mechanical in nature, and less attention is committed to understanding the(More)
Crosslinking is considered a possible approach to increasing the mechanical and structural stability and biodegradation resistance of the dentin collagen matrix. The aim of this study was to investigate the mechanical and chemical variations and collagen degradation resistance associated with crosslinking of the dentin collagen matrix with UVA-activated(More)
The purpose of this in vitro study was to evaluate the enamel and dentinal marginal sealing ability of three different cervical restorative systems. Class V preparations were made at the cementoenamel junction of 36 freshly extracted premolars. The teeth were randomly divided into three groups of 12 and restored with either a polyacid-modified resin(More)
BACKGROUND Basic fibroblast growth factor (bFGF; FGF-2) has been reported to facilitate wound healing and periodontal regeneration in experimental alveolar bone defects. The purpose of this study was to evaluate histologically the effect of topically applied bFGF with or without fibrin glue on delayed-replanted monkey teeth prone to replacement resorption.(More)
This study investigates the mechanical properties (hardness, flexural strength and compressive strength) of a new light-cured resin-modified glass ionomer cement (Fuji II LC Improved). Effects of the increased powder:liquid ratio on mechanical properties and the correlation between different mechanical properties were also studied. Mechanical properties of(More)
Glass-ionomer cements (GICs) are regarded as aqueous gels made up of polyalkenoic acid salts containing ion-leachable glass fillers. The consequence of water permeation across the GIC-dentin interface is unknown. This study used SEM, field-emission/environmental SEM (FE-ESEM), and TEM to examine the ultrastructure of GIC-bonded moist dentin. Dentin surfaces(More)
