Epidemiologic studies of risk and protective factors for poor oral health have mostly been among children and adults, seldom focusing on adolescents. The aims of this study were to examine whether serum cotinine, a marker of tobacco exposure, and serum vitamin D are independently

Salivary levels of antibacterial peptide (LL-37/hCAP-18) and cotinine in patients with chronic periodontitis.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND The purpose of this study is to examine the relationship between salivary LL-37 levels and clinical severity in patients with chronic periodontitis (CP). The presence/absence of four periodontopathic bacteria and salivary cotinine levels were also examined to assess the impact of these

Association of passive smoking with caries and related salivary biomarkers in young children.

Numai utilizatorii înregistrați pot traduce articole

OBJECTIVE To investigate the association between passive smoking, as determined by salivary cotinine level, and caries, salivary pH, buffering capacity, flow rate and microbiological counts in young children. METHODS Ninety passive smokers (PS) with a mean age of 5.02 years and 90 healthy

Is low birthweight associated with dental caries in permanent dentition?

Numai utilizatorii înregistrați pot traduce articole

The aim of this study was to test the hypothesis of association between low birthweight and dental caries. This study used data from the Third National Health and Nutritional Examination Survey, 1988-94 (NHANES III) including 7- to 11-year-old children with complete dental caries information (n =

Assessment of smoking status based on cotinine levels in nasal lavage fluid.

Numai utilizatorii înregistrați pot traduce articole

Cotinine is a principal metabolite of nicotine with a substantially longer half-life, and cotinine levels in saliva, urine or serum are widely used to validate self-reported smoking status. The nasal cavity and olfactory system are directly exposed to tobacco smoke in smokers and in non-smokers who

The Determinants of Salivary Cotinine Concentration in Smokeless Tobacco Users.

BACKGROUND Dental decay is the most common chronic disease of children and it disproportionately affects those living in poverty, but the reasons for this are not clear. Passive smoking may be a modifiable risk factor for dental caries. OBJECTIVE To examine the relationship between dental caries and

Structural Studies of Nicotinoids: Cotinine versus Nicotine.

Numai utilizatorii înregistrați pot traduce articole

Nicotinoids are agonists of the acetylcholine receptor (nAChR) and play important biochemical and pharmacological roles. Herein, we report on the structure and conformation of cotinine, and compare its molecular properties with the nicotine prototype, from which it only differs in the addition of a

The impact of smoking status, disease stage, and index tumor site on second primary tumor incidence and tumor recurrence in the head and neck retinoid chemoprevention trial.

Numai utilizatorii înregistrați pot traduce articole

Second primary tumors (SPTs) develop at an annual rate of 3-7% in patients with head and neck squamous cell cancer (HNSCC). In a previous Phase III study, we observed that high doses of 13-cis-retinoic acid reduced the SPT rate in this disease. In 1991, we launched an intergroup, placebo-controlled,

The use of digital peripheral artery tonometry to detect endothelial dysfunction in pregnant women who smoke.
