Mr. P is a 69-year-old male who presents with a chief complaint of, “I have neglected my teeth for 20 years and I’d like to have them fixed.” He is a lifelong nonsmoker, in good health, with no known drug allergies and no significant past medical history. Dental findings are notable for significant edentulousness: teeth numbers 1, 2, 3, 5, 7, 10, 13, 16, 17, 18, 19, 20, 30, 31, 32 are not prese...

BACKGROUND It is well known that treatment variation exists in oral healthcare, but the consequences for oral health are unknown as the development of outcome measures is still in its infancy. The aim of this study was to identify and develop outcome measures for oral health and explore their performance using health insurance claims records and clinical data from general dental practices. ME...

The Southwest Iberian Middle Bronze Age culture, although widespread in southern Portugal and nearby areas of southwest Spain in the Middle Bronze Age, is characterised by the scarcity of preserved human remains. Recent reanalysis of the human remains unearthed from the grave cists of the necropolis of Casas Velhas (Melides, Portugal), with a minimal number of 21 individuals (19 adults and 2 no...

BACKGROUND Recently, incorporation of nanohydroxyapatite (NHA) has been suggested to improve the mechanical properties of glass ionomers (GIs). This study aimed to assess the effect of addition of NHA on wear of resin modified glass ionomer (RMGI) by tooth brushing simulation. MATERIAL AND METHODS In this in vitro, experimental study, NHA in 1, 2, 5, 7 and 10wt% concentrations was added to Fu...

introduction: the aim of this study was to evaluate the influence of different levels of external irrigation during irradiation with an erbium, chromium: yttrium-scandium-gallium-garnet (er,cr:ysgg) laser on the roughness and wear of dental tissue during scaling procedures. methods: twenty-five uniradicular bovine teeth had the proximal surfaces planed and divided into 3 regions: upper, middle ...

Dental caries and wear are important conditions to record in archaeological collections. The aim of the present paper is to determine the frequency and distribution of dental caries and dental wear in a mediaeval Byzantine paediatric population in Yenikapı, Constantinople, Istanbul. The present research was carried out on the skeletal remains of 1 infant and 28 children with a total of 180 teet...

Not only can teeth provide clues about diet, but they also can be indicators of habitat quality. Conspecific groups living in different habitats with different kinds of foods may exhibit different rates of dental attrition because their teeth are less well adapted to some foods than to others. Ecological disequilibrium describes the situation in which animals live in habitats to which they are ...

background: the interim restorative materials should have certain mechanical properties to withstand in oral cavity. the aim of this study was to evaluate the hardness and wear resistance ofinterim restorative materials. materials and methods: fifteen identical rectangular shape specimens with dimensions of 2 mm × 10 mm × 30 mm were made from 7 interim materials (tempspan, protemp 3 garant, rev...

In this, the first of a four-part series on the restorative management of the worn dentition, the aetiological factors, diagnosis of toothwear and preventive measures are summarized. Later papers will deal with the management of localized anterior and posterior toothwear, the use of 'Dahl type' appliances as an effective means for the restorations and the various treatment options for the manag...
