Background: Dentists are at a higher risk of suffering from musculoskeletal disorders (MSD) than the general population. However, latest study investigating MSD in dental profession Germany was published about 20 years ago. Therefore, aim this to reveal current prevalence dentists and students Germany. Methods: The final size contained 450 (287 f/163 m) subjects different areas specialization. age participants ranged 23 75 years. questionnaire consisted modified version Nordic Questionnaire,...

Direct printed aligners (DPAs) offer benefits like the ability to vary layer thickness within a single DPA and 3D print custom-made removable orthodontic appliances. The biocompatibility of appliances made from Tera Harz TA-28 (Graphy Inc., Seoul, South Korea) depends on strict adherence standardized production post-production protocol, including UV curing. Our aim was evaluate whether design modifications that increase require longer curing time ensure biocompatibility. Specimens with...

This prospective study aimed to evaluate periodontal inflammation in adolescents undergoing orthodontic treatment with clear aligners (Invisalign® Teen, Align Technology, San Jose, CA, USA). Key objectives included assessing the presence of 11 periodontitis-associated marker bacteria, active matrix metalloproteinase-8 concentrations sulcular fluid, and influence IL-1 polymorphism genotypes on health. Fifty adolescent patients (13.3 ± 1.8 years) mixed permanent dentition participated....

How a dentist works, such as the patterns of movements performed daily, is also largely affected by workstation Dental tasks are often executed in awkward body positions, thereby causing very high degree strain on corresponding muscles. The objective this study to detect those dental tasks, during which postures occur most frequently. isolated analysis static will examine duration for these maintained dental, respectively non-dental, activities. Methods: 21 (11f/10 m) dentists (age: 40.1 ±...

In Germany, about 86.7 % of the dentists have stated to suffer from pain in neck and shoulder region. These findings are predominantly based on surveys. Therefore objective this study is conduct a kinematic analysis occupational posture dentistry.Twenty one (11 f/10 m; age: 40.1 ± 10.4 years) participated examination. The CUELA-System was used collect data activities an average dental workday. A detailed, computer-based task took place parallel Through synchronization collected both...

The number of studies investigating correlations between the temporomandibular system and body posture, postural control or plantar pressure distribution is continuously increasing. If a connection can be found, it often minor influence for only single parameter. However, small subject groups are critical. This study was conducted to define dental parameters, in healthy males.In this study, 87 male subjects with an average age 25.23 ± 3.5 years (ranging from 18 35 years) were examined....

The objective of this 2-arm parallel trial was to determine the plaque removal efficacy (main outcome) and motivation assessment (secondary comparing a manual versus an interactive power toothbrush in orthodontic patients.Sixty adolescents with fixed appliances both arches were randomized 1:1 ratio parallel, randomized, examiner-blind controlled clinical trial. Eligibility criteria included at least 16 natural teeth, 1-6 "focus care areas," score ≥1.75, no severe caries, gingivitis...

Traditional ergonomic risk assessment tools such as the Rapid Upper Limb Assessment (RULA) are often not sensitive enough to evaluate well-optimized work routines. An implementation of kinematic data captured by inertial sensors is applied compare two routines in dentistry. The surgical dental treatment was performed different conditions, which were recorded means (Xsens MVN Link). For this purpose, 15 (12 males/3 females) oral and maxillofacial surgeons took part study. Data post processed...

In general, the prevalence of work-related musculoskeletal disorders (WMSD) in dentistry is high, and dental assistants (DA) are even more affected than dentists (D). Furthermore, differentiations between fields specialization (e.g., general dentistry, endodontology, oral maxillofacial surgery, or orthodontics) rare. Therefore, this study aims to investigate ergonomic risk aforementioned four for D DA on one hand, compare within each individual field specialization.

Many adolescents have poor plaque control and sub-optimal toothbrushing behavior. Therefore, we compared the efficacy of an interactive power toothbrush (IPT) to a manual (MT) for reducing dental improving compliance. In this randomized, parallel single-blind clinical study, brushed twice daily with either MT (Oral-B® Indicator soft toothbrush) or IPT ProfessionalCare 6000 Bluetooth). Subjects 2 min, plus additional 10 s each 'Focus Care Area'. At screening Week 2, afternoon pre-brushing was...

Musculoskeletal disorders (MSD) are common among dental professionals. The most areas affected the trunk, neck, shoulders and wrists. Current evidence suggests that causes of MSD can be found in physical demands profession. Posture movement during treatment is influenced by arrangement concept (patient chair, equipment cabinets). It has not been investigated whether ergonomic risk differs between concepts.To evaluate prevalence professionals, 1000 responses will collected from a nationwide...

Musculoskeletal disorder (MSD) is already prevalent in dental students despite their young age and the short duration of practice. The current findings state that causes MSD are related to posture during work. This study aims investigate ergonomic risk students. In order analyze students, 3D motion analyses were performed with inertial sensors performance standardized activities. For this purpose, 15 assistant trainees (all right-handed) measured a team. Data analyzed using Rapid Upper Limb...

Dentists, including endodontists, frequently experience musculoskeletal disorders due to unfavourable working postures. Several measures are known reduce the ergonomic risk; however, there still gaps in research, particularly relation dental work different oral regions (Quadrants 1-4).

The occupation of dental assistants (DAs) involves many health risks the musculoskeletal system due to static and prolonged work, which can lead disorders (MSDs). aim study was investigate prevalence MSDs in DAs Germany. Methods: For this purpose, an online questionnaire analyzed 406 (401 female participants 5 male participants, 401w/5m) DAs. It based on Nordic Questionnaire (lifetime, 12-month, seven-day MSDs’ separated into neck, shoulder, elbow, wrist, upper back, lower hip, knee, ankle),...

The Rapid Upper Limb Assessment (RULA) is used for the risk assessment of workplace-related activities. Thus far, paper and pen method (RULA-PP) has been predominantly this purpose. In present study, was compared with an RULA evaluation based on kinematic data using inertial measurement units (RULA-IMU). aim study was, one hand, to work out differences between these two methods and, other, make recommendations future use respective basis available findings.For purpose, 130 (dentists + dental...

Craniomandibuläre Dysfunktionen sind eine Herausforderung. Ihre Ätiologie ist multifaktoriell, die Symptomatik facettenreich, pathologischen Mechanismen komplex. Julia Camilla Bulski und Christina Erbe erklären, warum Zahnfehlstellungen oder Zwangsbisse zu Schmerzen Verspannungen führen können. Eine optisch diskrete Abhilfe schaffen transparente herausnehmbare Zahnschienen, wobei Physiotherapie in der modernen Aligner-Therapie wichtige Rolle spielt.

Abstract Tooth gemination is a dental phenomenon in which single tooth bud attempts to divide into two, resulting the formation of structure that appears as two teeth but originates from same follicle. This partial separation often indicated clinically by groove or depression suggests presence distinct (Rajeswari M, Ananthalakshmi R. 2011. Gemination-case report and review. Indian Journal Multidisciplinary Dentistry). The distinction between fusion plays an important role treatment planning....

For dental professionals, musculoskeletal disorders (MSD) are common health hazards and resistance training programmes have been promising approaches in the quest for a reduction pain intensity of these professionals. Therefore, aim current study was to investigate effect trunk-oriented 10-week programme.In total, conducted with 17 dentists assistants (3 m/14 f) over course 10 weeks, workouts being performed 2 times week using 60 min intervention programme consisting 11 exercises. The...
