Comparison of a dentifrice containing 0.243% sodium fluoride, 0.3% triclosan, and 2.0% copolymer in a silica base, and a dentifrice containing 0.243% sodium fluoride in a silica base: a three-year clinical trial of root caries and dental crowns among adults.

Objective: Colgate Total toothpaste has been demonstrated to be highly effective in plaque and gingivitis control. The effect of triclosan on root caries and on the survival of dental crowns (fixed dental prosthetic treatment) has not been evaluated. In order to examine these important variables, a randomized controlled clinical trial was conducted comparing Colgate Total toothpaste with triclosan, and an identical fluoride toothpaste without triclosan.

A matter of timing: unsynchronized antigen expression and antigen presentation diminish secondary T cell responses.

Despite the low and short expression of secondary Ag, prime-boost immunizations using homologous or heterologous vectors are capable of amplifying memory CD8(+) T cells. This is mainly attributed to the rapid presentation of Ag by APCs and the high proliferative capacity of memory CD8(+) T cells. Nevertheless, certain viruses and vectors often require prolonged Ag presentation for optimal T cell priming, and the influence of such a prolonged presentation during secondary immune induction is not clear.

Are immigrant populations aware about their oral health status? A study among immigrants from Ethiopia.

Background: Evidence from Western countries indicates that there are fundamental discrepancies between self-perceived illness of immigrants and the provision of health care, according to the Western bio-medical health service model. These need to be understood in the planning and implementation stages of public health care programs for new immigrants. The objectives of the present study were to investigate self-perceived versus clinically diagnosed dental and periodontal health status among immigrants from Ethiopia.

Malposition of unerupted mandibular second premolar in children with palatally displaced canines.

Objective: To test the hypotheses that (1) the distal angulation of unerupted mandibular premolar (MnP2) is significantly greater in children with palatally displaced canines (PDC) than in those in a control sample; and (2) delayed tooth formation is significantly more frequent in children with both malposed MnP2 and PDC than in children with PDC only.

Materials And Methods: We examined retrospectively panoramic radiographs from 43 patients with PDC who had no previous orthodontics. A control sample consisted of age- and sex-matched patients.

The influence of an oral health education program provided in a community dental clinic on the prevalence of caries among 12-14 year-old children.

Objectives: To evaluate the effectiveness of an oral health education program when given in a public dental clinic, by assessing caries and restorations.

Methods: This was done by assessing changes in caries prevalence in the mouth of children aged 12 to 14 year- old. Data was obtained from files of patients treated in the Dental Volunteers for Israel (DVI) clinic in Jerusalem.

Oral vs. pharyngeal dysphagia: surface electromyography randomized study.

Background: A clear differential diagnosis between oral and pharyngeal dysphagia remains an unsolved problem. Disorders of the oral cavity are frequently overlooked when dysphagia/odybophagia complaints are assessed. Surface electromyographic (sEMG) studies were performed on randomly assigned patients with oral and pharyngeal pathology to evaluate their dysphagia complaints for the sake of differential diagnosis.

Conventional wisdom and the surgical exposure of impacted teeth.

Objectives: To provide evidence against the notion that direct contact between the crown of an impacted tooth and alveolar bone is an impediment to orthodontically assisted eruption of teeth.

Setting And Sample Population: The Department of Orthodontics at the Hebrew University-Hadassah School of Dental Medicine, in Jerusalem, Israel, and the private practices of the authors.

Materials And Methods: Patients reported were those affected by impacted teeth, including individuals who were normal healthy patients, with and without resorption of the adjacent incisor roots, as well as individuals suffering from Cleidocranial dysplasia and increased bone density, and individuals with autogenous and synthetic bone grafts.

Oral and facial trauma among paratroopers in the Israel Defense Forces.

Background: Military fighters are one of the highest risk populations for dental and oro-facial trauma. The aim of this study was to evaluate the incidence and etiology of oro-facial injuries among active duty paratroopers in the Israeli Defense Forces.

Methods: Paratroopers from selected companies were interviewed using a structured questionnaire regarding oro-facial trauma during active service years.

Promoter hypermethylation of mismatch repair genes, hMLH1 and hMSH2 in oral squamous cell carcinoma.

Objectives: Major risk factors of oral squamous cell carcinoma (OSCC) are environmental and can lead to DNA mutagenesis. Mismatch repair (MMR) system functions to repair small DNA lesions, which can be targeted for promoter hypermethylation. We therefore wanted to test whether hypermethylation of MMR genes (hMLH1, hMSH2) could contribute to oral carcinogenesis by correlating the information to patient clinical data.

Oral effects of nonmyeloablative stem cell transplantation: a prospective observational study.

Objective: Nonmyeloablative stem cell transplantation (NST) is a relatively new type of hematopoietic stem cell transplantation (HSCT) that has gained wider use in the last decade. Oral effects of NST have not been described. The goal of the study was to evaluate the oral mucosal effects, including oral acute graft versus host disease (aGVHD), in patients undergoing NST in comparison to patients undergoing myeloablative HSCT.

Lingual orthodontic treatment and absolute anchorage to correct an impacted maxillary canine in an adult.

There are 2 major drawbacks to the classic orthodontic-surgical approach for resolution of impacted teeth in adults: appearance and duration of treatment. This case report illustrates the lingual orthodontic treatment of an adult with an impacted maxillary canine; absolute anchorage was achieved with a miniscrew placed in the palate. The combination of invisible appliances and a nondental anchorage system is particularly useful in adults and should make treatment available to more patients.

Oral hygiene improvement: a pragmatic approach based upon risk and motivation levels.

Good oral hygiene has always been the cornerstone of public and private dental health promotion. However, this has often been based upon incorrect assumptions. The public is not always willing and does not always need to change its oral health behavior to the same extent as that expected by the dental profession.

Dentists' knowledge and implementation of the 2007 American Heart Association guidelines for prevention of infective endocarditis.

Objectives: Our aim was to evaluate the knowledge and implementations of the 2007 American Heart Association guidelines for the prevention of infective endocarditis (IE) among practicing Israeli dentists, 12 months after their publication.

Study Design: A total of 118 dentists completed a questionnaire regarding required antibiotic prophylaxis for 10 specific cardiac patient subtypes before invasive dental treatment, prophylactic need in at-risk patients for IE in 10 dental procedures, and prophylactic regimen for nonallergic patients.

Results: Correct answer response for cardiac conditions was 81.

Fasting state and episodes of vomiting in children receiving nitrous oxide for dental treatment.

Purpose: The purpose of this controlled-crossover study was to determine the frequency of vomiting during nitrous oxide / oxygen analgesia (NOA) and assess the relationship between fasting status and vomiting.

Methods: One hundred and thirteen children (64 male, 49 female), ranging in age from 24-160 months (mean = 74) and a mean weight of 23 kg (range 11-60 kg), participated in the study. At the initial examination, subjects were randomly assigned to be either fasting on the first appointment and non-fasting during the second appointment or alternatively be non-fasting for the first appointment and fasting for the second.

Changing dental caries and periodontal disease patterns among a cohort of Ethiopian immigrants to Israel: 1999-2005.

Background: Dental epidemiology has indicated that immigrants and minority ethnic groups should be regarded as high risk populations on the verge of oral health deterioration. The objectives of this study were to measure the changing pattern of dental caries, periodontal health status and tooth cleaning behaviour among a cohort of Ethiopian immigrants to Israel between the years 1999-2005.

Methods: Increment of dental caries and periodontal health status was recorded among a cohort of 672 Ethiopian immigrants, utilizing the DMFT and CPI indices.

Replantation of an immature permanent central incisor following pre-eruptive traumatic avulsion.

Tooth avulsion represents 0.5-16% of traumatic injuries. Avulsion of a pre-eruptive left permanent maxillary incisor in a 6-year-old boy is presented.

Dental trauma among 5th and 6th grade Arab schoolchildren in Eastern Jerusalem.

Dental trauma is an irreversible pathology which after occurrence is characterized by life long debilitating effects. The objective of the study was to measure the prevalence of trauma in anterior permanent teeth among children and associations with independent variables. A total of 453 5th and 6th grade Arab Eastern Jerusalem schoolchildren participated.

[Satisfaction survey of the dental treatment project of Hadassah and the "International Fellowship of Christians and Jews" among the family and the professional servant].

Unlabelled: Social inequalities in health are a serious public health problem. In Israel dental treatment is not included in the national health insurance. Low socio-economic groups are therefore significantly inferior in oral and dental health.

Pilot study of rapid caries treatment needs screening--a brief communication.

Objective: To evaluate a newly developed screening method for caries-related treatment needs.

Methods: The Rapid Caries Treatment Needs Screening (RCTNS) Index includes five ordinal nominal scores. Comparisons with conventional examinations were conducted among 565 young Israeli adults (aged 23 +/- 5.

Aim: Our aim was to evaluate the periodontal status and present smoking habits among a representative sample of young adult Israelis and to investigate possible associations.

Material And Methods: A representative sample of young adult Israelis was examined and interviewed on the day of release from compulsory military service. Collected data included demographic background (gender, education level, family size and father's country of origin) and current smoking habits.

Effect of liquid-polish coating on in vitro biofilm accumulation on provisional restorations: Part 2.

Objective: In part 1 of this study, the authors showed that coating polymethyl methacrylate (PMMA) provisional restorations with bonding resin (BR) or liquid polish (LP) significantly reduced early in vivo biofilm formation on these restorations. The aim of the present study was to determine the mechanism through which these materials inhibit biofilm formation.

Method And Materials: The antimicrobial properties of the tested materials were examined using the agar diffusion test (ADT) and the direct contact test (DCT).

A novel microscopic assay for oral malodor-related microorganisms.

Previous research has shown that the production of volatile sulfide compounds (VSC) by oral bacteria is associated with oral malodor. In the present study, we report a novel technique (microscopic sulfide assay (MSA)) for the quantification of VSC-producing oral microorganisms. The MSA was performed by overnight incubation of saliva samples in the presence of ferrous sulfate and sodium thiosulfate, followed by digital analysis of cells stained black due to cell-associated precipitation of ferric sulfide.
