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.

Acid resistance of the enamel in primary second molars from children with down syndrome and cerebral palsy.

Objectives: This study was carried out to evaluate the extent of differences in mineralization of inner and outer enamel of the lower primary second molars of children with Down syndrome (DS) and Cerebral Palsy (CP) as revealed by acid treatment of exfoliated teeth. The results were compared to those obtained from a control group of healthy children.

Methods: The sample included 4 mandibular second molars from each group.

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.

Degradation of collagen-guided tissue regeneration membranes by proteolytic enzymes of Porphyromonas gingivalis and its inhibition by antibacterial agents.

Previous studies have shown that whole cells of several periodontal pathogenic bacteria including Porphyromonas gingivalis may degrade the clinically used regeneration membranes Biomend Extend and Bio-Gide. Fractionation of P. gingivalis cells revealed that cell membrane-associated proteases are responsible for the in vitro degradation of the collagen membranes.

[Chronic graft-versus-host-disease involving the oral mucosa: clinical presentation and treatment].

Graft versus host disease (GVHD) is an alloimmune inflammatory process, which results from a donor-origin cellular response against host tissues. The chronic syndrome of GVHD (cGVHD) occurs in approximately 50% of patients post hematopoietic stem cell transplantation (HSCT) and remains the leading cause of non-malignant mortality. Oral cavity is one of the most frequent sites involved in cGVHD, possibly only second to skin.

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.

Erectile dysfunction might be associated with chronic periodontal disease: two ends of the cardiovascular spectrum.

Introduction: Both chronic periodontal disease (CPD) and erectile dysfunction (ED) are associated with cardiovascular disease and its risk factors, including smoking and diabetes mellitus. However, the association between ED and CPD has never been studied.

Aim: To study the association between ED and CPD.

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.

Periodontal status of impacted maxillary incisors uncovered by 2 different surgical techniques.

Purpose: The aim of this retrospective study was to compare the postretention clinical appearance and the pulpal and periodontal status of surgically exposed and orthodontically aligned impacted maxillary central incisors, treated by 2 different surgical techniques-open eruption (OE) versus closed eruption (CE).

Patients And Methods: The OE group consisted of 11 patients, age 15 to 38 years. The 11 patients in the CE sample (aged 14-28 years) were selected from a larger group of patients treated by this method, by carefully matching them to the patients in the OE group, in terms of cause and height of impaction.

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.

Rapidly progressive internal root resorption: a case report.

The etiology of internal root resorption is not fully understandable, trauma and chronic pulpitis are considered the main risk factors. Usually the process is asymptomatic and diagnosed upon routine radiographic examination. This case report presents a rapid progression of internal resorption related directly to traumatic injury.

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.

Compliance of children and youngsters in the use of mouthguards.

The purpose of the study was to examine the compliance of children wearing their mouthguards, and to evaluate socio-environmental factors that impact upon the usage of the device. Eighty children attending the student clinic of the Hadassah School of Dental Medicine received mouthguards free of charge. One year later, 69 participants and their parents answered a survey aimed at gaining information regarding compliance and comfort when wearing the mouthguard correlated with gender, ages of parents and child, number of siblings, position of child in the family, socio-economic status, education of parents and past dental injuries of siblings or parents.

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.
