Eugenol-containing dental materials are frequently used in clinical dentistry. When zinc oxide-eugenol (ZOE) is applied to a dentinal cavity, small quantities of eugenol diffuse through the dentin to the pulp. Low concentrations of eugenol exert anti-inflammatory and local anesthetic effects on the dental pulp. Thus use of ZOE temporary filling may(More)
BACKGROUND Periodontitis develops in a time-dependent manner. Cross-sectional studies document one moment in time but fail to capture the progressive nature of disease. Radiographic measures of bone loss are relatively insensitive but are reliable markers of irreversible disease. Longitudinal studies are needed to identify biomarkers that can precede(More)
The objectives of this paper are to present an overview of children's oral health-related quality of life and include specific applications for using quality of life assessment in dental research. The process of developing pediatric oral health- related quality of life measures, in particular the Child Oral Health Impact Profile, is outlined. Examples of(More)
Aggregatibacter actinomycetemcomitans-induced localized aggressive periodontitis (LAP) in African-American adolescents has been documented but is poorly understood. Two thousand fifty-eight adolescents aged 11 to 17 years were screened for their periodontal status and the presence of A. actinomycetemcomitans in their oral cavity. Seventy-one A.(More)
Aggregatibacter actinomycetemcomitans is frequently associated with localized aggressive periodontitis (LAP); however, longitudinal cohort studies relating A. actinomycetemcomitans to initiation of LAP have not been reported. A periodontal assessment was performed on 1,075 primarily African-American and Hispanic schoolchildren, ages 11 to 17 years. Samples(More)
Vital bleaching procedures are a popular means of improving the appearance of discolored teeth. There is a wide array of whitening products for home and dental office use; all involves placing peroxide containing gels or solutions in contact with the teeth. In order to whiten teeth peroxide has to be able to penetrate tooth structure and oxidize colored(More)
Nerve activity was recorded from deep dentinal cavities in the canine teeth to assess the possible influence of potassium and divalent cations in decreasing this activity in hypersensitive teeth. The decreased activity after the topical application of 0.756 mol/l KCl to the cavity was primarily due to the cation. KCl elicited a biphasic response from(More)
BACKGROUND The aim of this study is to compare the colonization, immunoglobulin (Ig) G response, and alveolar bone loss in Aggregatibacter actinomycetemcomitans (Aa)-inoculated Fawn Hooded Hypertensive (FHH), Dahl Salt-Sensitive (DSS), and Brown Norway (BN) rats. METHODS Each rat strain was divided into wild-type Aa-inoculated and non-inoculated control(More)
AIM This study was designed to investigate the utility of two "new" definitions for assessment of bone loss in a rodent model of periodontitis. MATERIAL AND METHODS Eighteen rats were divided into three groups. Group 1 was infected by Aggregatibacter actinomycetemcomitans (Aa), group 2 was infected with an Aa leukotoxin knock-out, and group 3 received no(More)
Many patients complain of teeth that are painful when exposed to a variety of harmless thermal and tactile stimuli. Sensitive tooth necks and root surfaces frequently are the unintentional by-products of aggressive oral hygiene practices and periodontal treatment. Dentists and the afflicted patients have resorted to many remedies for this common form of(More)
