[Resin-bonded fixed partial dentures in the anterior area].

In essence the resin-bonded fixed partial denture, or resin-bonded bridge, is an artificial tooth that is bonded to 1 or 2 abutment teeth. If the resin-bonded bridge is directly made with resin composite intra-orally, then the connector area is the weakest link. The alternative is to produce an indirect resin-bonded bridge in which a metal or ceramic frame spans the space between the abutments.

[Indirect adhesive bridges in the lateral parts].

On the basis of a case, this study considers which prosthetic device is suitable as a replacement for a first molar. At the request of the patient, the least invasive option was sought. The outcome in this case was that the adhesive bridge with abutment teeth with class-2 restorations might be suitable.

Natural History of Mandibular Function in Spinal Muscular Atrophy Types 2 and 3.

Background: Hereditary proximal spinal muscular atrophy (SMA) is characterized by abnormal alpha motor neuron function in brainstem and spinal cord. Bulbar dysfunction, including limited mouth opening, is present in the majority of patients with SMA but it is unknown if and how these problems change during disease course.

Objective: In this prospective, observational, longitudinal natural history study we aimed to study bulbar dysfunction in patients with SMA types 2 and 3.

Diagnostics and Management of Pediatric Headache: An Exploratory Study among Dutch Physical Therapists.

Physiotherapists are often part of a multidisciplinary treatment plan for children with headaches. The literature on physical therapeutic diagnostics and management of headaches is often focused on adults. To gain insight, identify knowledge gaps, and increase the evidence needed for clinical physical therapeutic practice with children with headaches, an exploratory method is warranted.

Biomechanical properties of different endocrown designs on endodontically treated teeth.

Objective: To compare the biomechanical properties of different endocrown designs on endodontically treated teeth with an extensive defect in the mesial wall using a three-dimensional finite element method (3D FEM).

Methods: Four finite element analysis models were designed and built up based on different endocrown configurations in a mandibular molar. One model was designed as a butt joint preparation with 2 mm occlusal thickness(control), the other three models were butt joint designs with different distances between the bottom of the mesial wall preparation and the cemento-enamel junction (CEJ): 2 mm, 1 mm and 0 mm respectively.

Interprofessional learning in a student-run dental clinic: The effect on attitudes of students in oral healthcare.

The purpose of this study was to gain insight into change in attitudes held by students in oral healthcare about interprofessional learning and collaboration after one year of work in a student-run dental clinic (SRDC). Third- and fourth-year bachelor of dental hygiene students (n = 221) and first- and second-year master of dentistry students (n = 203) participated in baseline and follow-up measurements and completed 570 questionnaires. The Readiness for Interprofessional Learning Scale (RIPLS) was used to measure changes in attitudes toward Interprofessional Education (IPE) during participation in the SRDC.

Coherence of jaw and neck muscle activity during sleep bruxism.

Background: Studies have shown co-contraction of jaw and neck muscles in healthy subjects during (sub) maximum voluntary jaw clenching, indicating functional inter-relation between these muscles during awake bruxism. So far, coherence of jaw and neck muscles has not been evaluated during either awake or sleep bruxism.

Objective: The objective of this study was to evaluate the coherence between jaw and neck muscle activity during sleep bruxism.

[Oral healthcare for frail and care-dependent older people in Germany and the Netherlands].

To improve oral health for frail and care-dependent older people, both intra- and extramurally, in the Euregio Rhine-Waal area in the Netherlands and Germany, we inventoried barriers to oral care for the target group according to the literature, the organisation of oral care in both countries and the implications of this organisation for daily and professional (oral) healthcare and oral care. Results show most identified barriers are common to both countries, but the organisation of oral healthcare differs in both countries. The main differences lie in the financing and organisation of oral care in the intramural situation.

[Wish fulfilling medicine and wish fulfilling dentistry: legal aspects].

Wish fulfilling medicine (human enhancement (therapy)) concerns medical treatment without a direct medical need. In traditional medicine, a classical triad applies: 1. after investigation symptoms of illness lead to 2.

[Wish fulfilling medicine and wish fulfilling dentistry: -medical-ethical aspects].

Wish fulfilling medicine comprises medical procedures applied without a direct medical need. In such procedures, the medical-ethical principles can come under pressure: the autonomy of the patient, when wishes originate from social pressure; beneficence when the (underlying) aim and consequences are unclear; and 'doing no harm', when that appears to be impossible. The principle of justice, too, could come under threat when especially those with a privileged socio-economic background can take advantage of wish fulfilling medicine.

[Wish fulfilling medicine and wish fulfilling dentistry: what does this mean?].

Wish fulfilling medicine refers to medical procedures applied without a direct medical need. In wish fulfilling medicine, the wish of the patient is dominant, but wish fulfilling medicine is also promoted indirectly by healthcare providers, (pharmaceutical) companies and healthcare insurers. Wish fulfilling medicine often concerns the enhancement of appearance or performance; therefore, wish fulfilling medicine is also referred to as (human) enhancement (therapy).

Association between self-reported bruxism and anger and frustration.

Background: Even though bruxism has been shown to be associated with several psychological factors, few studies have been performed on its relationships with anger and frustration.

Objective: This study aimed to determine the association between self-reported awake and sleep bruxism and anger and frustration.

Methods: In this longitudinal observational study, 55 healthy adult participants with "possible" bruxism reported their experienced level of bruxism and several psychosocial factors and lifestyle factors for 28 consecutive days using a personal logbook.

Masticatory muscle stretching for the management of sleep bruxism: A randomised controlled trial.

Background: Sleep bruxism is a phenomenon associated with masticatory muscle hyperactivity. While stretching of limb and trunk muscles has been extensively studied for musculoskeletal disorders, little is known about the effectiveness of stretching of masticatory muscles in the management of bruxism.

Objective: The aim of this study is to determine the effectiveness of stretching of the masticatory muscles for sleep bruxism.

Masticatory efficiency in patients with partially dentate dentitions.

Objectives: To assess associations amongst masticatory performance, dental functional status, and perceived chewing problems with common soft and hard foods.

Materials And Methods: 387 adult participants with reduced natural dentitions were included and underwent an oral examination, completed a written structured questionnaire and performed a two-color chewing gum test for masticatory efficiency. A multivariate regression model was used to analyze associations between masticatory efficiency and a number of dental conditions, with age, gender and perceived chewing difficulties as background variables.

The relationship between masticatory ability, age, and dental and prosthodontic status in an institutionalized elderly dentate population in Qingdao, China.
