One of the goals of evolutionary developmental biology is to link specific adaptations to changes in developmental pathways. The dentition of cypriniform fishes, which in contrast to many other teleost fish species possess pharyngeal teeth but lack oral teeth, provides a suitable model to study the development of feeding adaptations. Here, we have examined the involvement of retinoic acid (RA) ...

Here, we report the management of a type I endoperiodontal lesion with furcation bone loss. A 59-year-old female attended our hospital with the chief complaint of mobility of tooth 46 and recurrent gingival swelling around the tooth. She previously received dental treatment from two dentists, but her condition did not improve. The tooth manifested the symptoms of typical periodontitis, such as ...

The aim of this study was to estimate the prevalence of tooth loss among Brazilian adults aged 35 to 44 years. The study also tested the association between tooth loss and demographic, socioeconomic, and dental-care utilization variables. Data were analyzed from 13,431 individuals submitted to dental examination and interviewed in the National Oral Health Survey in 2002-2003. The number of lost...

BACKGROUND A growing body of evidence has indicated a possible association between oral and gastrointestinal (orodigestive) cancers and periodontal disease or tooth loss. However, the evidence remains contradictory. This study investigated whether tooth loss, which is indicative of poor oral health and a potential source of oral infections, is associated with death from orodigestive cancer. M...

Periodontal disease is an infectious disease causes my microorganisms resulting in the corrosion of tissues around the tooth surface and soft tissue lining the mouth, loss of connective tissue attachment, breakdown of bone that holds the teeth, and tooth loss [1]. The symptoms are bleeding gum (gingivitis), gingival pockets and bone loss (periodontal disease) leading to tooth mobility and event...

OBJECTIVE To estimate the mean number of missing teeth, lack of functional dentition and total tooth loss (edentulism) among adolescents, adults and the elderly in Brazil, comparing the results with those of 2003. METHODS Data from 5,445 adolescents aged 15-19, 9,779 adults aged 35-44 and 7,619 elderly individuals aged 65-74, participants in the Brazilian Oral Health Survey (SBBrasil) 2010, w...

Our aim was to predict tooth surface loss in individuals without the need to conduct clinical examinations. Artificial neural networks (ANNs) were used to construct a mathematical model. Input data consisted of age, smoker status, type of tooth brush, brushing, and consumption of pickled food, fizzy drinks, orange, apple, lemon, and dried seeds. Output data were the sum of tooth surface loss sc...

INTRODUCTION Little is known about the effect of cigarette smoking cessation on risk of tooth loss. We examined how risk of tooth loss changed with longer periods of smoking abstinence in a prospective study of oral health in men. METHODS Research subjects were 789 men who participated in the Veterans Administration Dental Longitudinal Study from 1968 to 2004. Tooth status and smoking status ...

The aim of this study was to evaluate the association between tooth loss and overweight/obesity in an adult Brazilian population. It is a cross-sectional study comprising 3,930 adults [1,744 men and 2,186 women; median age of 40 y (ranging 20-59); 16.9% obese; 7.3% almost all or all teeth missing]. Data were collected using a self-administered questionnaire for tooth loss (4 categories), diet, ...
