To provide an anatomical basis for clinical implant esthetics, we evaluated the morphology of the nasopalatine canal (NPC) and analyzed labial and interproximal bone anatomy at the maxillary anterior region. We sought to investigate the effect of maxillary protrusion and tooth labiolingual inclination on labial bone anatomy in Chinese adults. Three dimensional (3D) images were reconstructed usi...

OBJECTIVE To detect changes in the microbial richness of dental plaque and oral behaviors during caries development in young Chinese children. METHODS Supragingival plaque samples and a survey of oral behaviors of 130 children aged 3 at baseline were analyzed at 6 months and 12 months. Total DNA was isolated from all samples and PCR-denaturing gradient gel electrophoresis analysis was conduct...

The prediction of caries risk has been of long-standing interest. Generally, few of the tests involving oral bacteria or their products have become accepted. Presently, the main focus is on counts of lactobacilli (L) and mutans streptococci (MS). Due to their positive numerical association with human caries and the linkage of this association to carbohydrate consumption, counts of L and MS may,...

BACKGROUND It has been suggested that dental caries should be regarded as a chronic disease as many individuals repeatedly develop new caries lesions. How this is perceived by caries active patients is unclear. The aim of this study was to measure patient-reported attitudes and negative experiences related to caries and dental treatment. METHODS A questionnaire was mailed to 134 caries active...

background: to assess the caries risk among 12‑years old children using the cariogram and to evaluate it by comparing with the actual change in dmft and dmfs over a period of two year. methods: a two year prospective study was conducted among 12 years age group school going children in davangere city. at the baseline relevant and required information regarding the oral hygiene, diet, fluoride u...

T he technique of cementing orthodontic bands to teeth was first introduced by Magil I in 1871 and remained the treatment of choice for more than 85 years. Direct bonding has replaced anterior teeth banding and offers significant advantages such as improved esthetics, ease of placement, patient comfort, decreased soft tissue irritation, enhanced ability to detect interproximal decay, and less d...

BACKGROUND One of the causative factors in development of dental caries is microorganisms. Two species of Mutans streptococci including Streptococcus mutans and Streptococcus sobrinus are associated with dental caries in human beings. The aim of this study was to investigate the frequency of S. mutans and S. sobrinus in saliva of children with different caries activity and ability to form biofi...

The prevalence of dental caries (tooth decay) in early childhood is high. Early childhood caries (ECC) is associated with caries in permanent dentition and lethal systemic infections. In many developed countries, 25% of children bear 75-80% of caries lesions. Caries prevention should be targeted at high-risk individuals. Identifying high-risk preschoolers through caries risk assessment (CRA) is...

The objectives of this prospective, longitudinal, population-based study were to estimate the incidence of dental caries in the primary dentition, identify risk factors and determine the proportion of children receiving dental treatment, through a two-year follow up. The first dental exam was conducted with 381 children aged one to five years, at health centers during immunization campaigns; 18...

The reproducibility of measurements of alveolar bone loss on radiographs may be a problem on epidemiologic studies, as they are based on comparisons of the diagnosis of various examiners. The aim of the present research paper was to assess the inter- and intra-examiner reproducibility of measurements of the interproximal alveolar bone loss on non-manipulated digital radiographs and after the ap...
