Dental hygienists in Israel: employment evaluation, job satisfaction, and training implications.

Fundamental changes have occurred in dental services for children in Israel that are likely to affect workforce needs for dental hygienists. The aim of this study was to describe the employment situation and job satisfaction of a sample of dental hygienists in Israel, to estimate associated variables, and to discuss corresponding possible implications for training programs after these changes. An e-mailed questionnaire sent to all dental hygienists in the Israeli Dental Hygienists Association list included questions about respondents' demographic background, years of experience, working hours, desire to work in an alternative occupation, and sense that they were valued within the dental community.

Primary lymphoma of the mandible masquerading as bisphosphonate-related osteonecrosis of jaws.

A 66-year-old osteoporotic woman suffered from long-term mental paresthesia (numbness), facial swelling, and a nonhealing extraction site. Fulfilling the three clinical diagnostic criteria for bisphosphonate-related osteonecrosis of the jaw (BRONJ; exposed bone for at least 8 weeks, current bisphosphonate [risedronate] treatment, and no history of head and neck radiation therapy), she was diagnosed and treated accordingly. Nevertheless, a later histopathologic examination revealed malignant lymphoproliferative infiltration of large and intermediate cells.

Influence of blue light on Streptococcus mutans re-organization in biofilm.

Our aim was to examine the viability and structure of new biofilm formed by Streptococcus mutans that was previously exposed to blue light. S. mutans bacteria were grown to form a mature biofilm, that was exposed to blue light (wavelengths, 400-500 nm) for 1-10 min (equivalent to 68-680 J/cm(2)).

The importance of a thorough medical and pharmacological history before dental implant placement.

The risk of osteonecrosis in patients treated with bisphosphonates is well known and guidelines intended to prevent this complication have been established and accepted. Bisphosphonate related osteonecrosis of the jaws (BRONJ) is a unique condition in which even past administration of medication may be of current and future relevance. We present a case of BRONJ in the maxilla after dental implant placement.

Light therapy: complementary antibacterial treatment of oral biofilm.

Conventional antibacterial treatment fails to eradicate biofilms associated with common infections of the oral cavity. Unlike chemical agents, which are less effective than anticipated, owing to diffusion limitations in biofilms, light is more effective on bacteria in biofilm than in suspension. Effectiveness depends also on the type and parameters of the light.

Mandibular block or maxillary infiltration: does it influence children's opposition to a subsequent dental visit?

Purpose: Local anesthesia by mandibular block or maxillary infiltration is commonly administered to children receiving dental treatment of primary molars. Discomfort, when presenting, most often involves the lower lip. The purpose of this study was to investigate whether children would be more opposed to attending a dental treatment following anesthesia by mandibular block than by maxillary infiltration.

Wettability versus electrostatic forces in fibronectin and albumin adsorption to titanium surfaces.

Objectives: Although the enhancement of plasma protein adsorption to titanium ( Ti ) following wetting has been recognized, the relationship between wettability and electrostatic forces has remained unclear. Thus, we have carried out a series of studies to determine the role of wettability and electrostatic forces on protein adsorption.

Methods: Titanium disks with different surfaces were wetted with a range of solutions, two of which contained divalent positive ions ( Ca and Mg ).

Dental management of pediatric HIV patients--state of Israel, Ministry of Health Project at Rambam Health Care Campus, 2006-2011.

Over two million children around the world are living with AIDS.

Oral and pharyngeal cancer among the Arab population in Israel from 1970 to 2006.

Background: Israeli Arabs are considered as a developing society characterized by poverty and high levels of smoking among men. The purpose of this study was to describe their incidence, mortality and survival rates for oral and pharyngeal cancer between the years 1970-2006. Studies such as this in the Arab world, where the population is almost the same as the Arab population in Israel, are rare.

Langerhans cells down-regulate inflammation-driven alveolar bone loss.

Excessive bone resorption is frequently associated with chronic infections and inflammatory diseases. Whereas T cells were demonstrated to facilitate osteoclastogenesis in such diseases, the role of dendritic cells, the most potent activators of naive T cells, remains unclear. Using a model involving inflammation-driven alveolar bone loss attributable to infection, we showed that in vivo ablation of Langerhans cells (LCs) resulted in enhanced bone loss.

Urban legends series: Sjögren's syndrome.

Sjögren's syndrome (SjS) is one of the most common autoimmune rheumatic diseases, clinically characterized by xerostomia and keratoconjunctivitis sicca. We investigated the following controversial topics: (i) Do we have reliable ways of assessing saliva production? (ii) How important are the quantity and quality of saliva? (iii) Are only anti-SSA/Ro and anti-SSB/La relevant for the diagnosis of SjS? (iv) Are the American-European Consensus criteria (AECC) the best way to diagnose SjS? Results from literature searches suggested the following: (i) Despite the fact that numerous tests are available to assess salivation rates, direct comparisons among them are scarce with little evidence to suggest one best test. (ii) Recent developments highlight the importance of investigating the composition of saliva.

Trends and distribution of oral and pharyngeal lymphoma in Israel.

Objectives: To describe the distribution and trends of oral and pharyngeal lymphoma cases in Israel.

Methods: Incidence rates were derived from the Israel National Cancer Registry and included all registered data from 1970 to 2006. Oral lymphoma included the tongue, mouth, salivary glands, tonsils, and pharynx.

The purpose of the present in vitro study was to evaluate the potential of GC Tooth Mousse to enhance remineralization of initial demineralized enamel sites in primary teeth.

Methods: Forty-four demineralization sites were created in 22 extracted primary teeth.

The social and behavioural pathway of dental caries experience among Jewish adults in Jerusalem.

Aims: To report dental caries status, related health behaviours and social determinants among a representative sample of adults residing in Jerusalem.

Methods: This cross-sectional study was conducted using a stratified sample of 254 Jewish and married adults aged 35-44 years in Jerusalem. Dental caries status was examined according to DMFT, percentage of caries-free persons and of people maintaining all their natural teeth (no teeth missing due to caries).

Painful trigeminal neuropathy induced by oral bisphosphonate-related osteonecrosis of the jaw: a new etiology for the numb-chin syndrome.

We describe the management of BRONJ triggered by dental implants in a patient on oral bisphosphonates. The sequestrum in the body of the mandible was large and involved the inferior alveolar nerve, causing a painful neuropathy. A successful outcome was obtained by combining conservative and surgical interventions.

The challenge of C-shaped canal systems: a comparative study of the self-adjusting file and ProTaper.

Introduction: C-shaped canals are anatomic features that present the clinician with both diagnostic and operational challenges. The aim of this study was to compare the efficacy of the Self-Adjusting File (SAF; ReDent, Ra'anana, Israel) in shaping C-shaped canals with that of the rotary ProTaper file system (Dentsply-Maillefer, Ballaigues, Switzerland).

Methods: Sixteen mandibular second molars and 4 maxillary second molars with C-shaped canals were obtained, originating from native Chinese population.

Parental cooperation scale in the pediatric dentistry setting: reliability and criteria.

Objective: The purpose of this study was to provide reliability and criteria data on a newly defined parental cooperation scale (PCS) and in addition correlate between parent scores and their child's behavior in the dental setting.

The antibacterial activity of LL-37 against Treponema denticola is dentilisin protease independent and facilitated by the major outer sheath protein virulence factor.

Host defense peptides are innate immune effectors that possess both bactericidal activities and immunomodulatory functions. Deficiency in the human host defense peptide LL-37 has previously been correlated with severe periodontal disease. Treponema denticola is an oral anaerobic spirochete closely associated with the pathogenesis of periodontal disease.

Is religiosity related to periodontal health among the adult Jewish population in Jerusalem?
