RESUMEN

To date, risk factors for temporomandibular joint (TMJ) sounds are still not completely understood, and anatomical factors are suspected to influence their occurrence. This study aimed to evaluate the impact of body constitution on temporomandibular joint sounds of adolescents. 10- to 18-year-old participants of the LIFE Child Study were examined for TMJ sounds, and physical parameters such as body height, body weight, and general laxity of joints were measured. Odds ratios (OR) for associations of TMJ sounds and standard deviation scores (SDS) of body height and body weight were calculated by using binary logistic regression, including cofactors such as age and number of hypermobile joints. The OR for TMJ sounds and SDS of body height was 1.28 (95% confidence interval (CI) 1.06; 1.56) in females when the age-adjusted height value was above 0. SDS of body weight indicated significant ORs for TMJ sounds in males with values of 0.81 (95% CI 0.70; 0.94). No correlation was detected for SDS values and TMJ crepitus. Tall female adolescents seem to be more prone to TMJ clicking sounds, while their occurrence seems less likely in male adolescents with higher body weight.

RESUMEN

Objectives: An abnormal development of teeth can result in malformed teeth. Indirect resin composites that can be fabricated with the computer-aided design/computer-aided manufacturing (CAD/ CAM) technique are available for the fabrication of permanent restorations. This case report presents the esthetical and functional rehabilitation of a 10-year-old female patient with oligodontia and conical canines. Material and Methods: Crowns fabricated from indirect resin composites were milled and polished to restore the conical canines 23, 33, and 43 (FDI). In addition, direct resin composite fillings were applied to teeth 53, 52, and 11, and a resin-bonded fixed dental prosthesis with single-retainer design fabricated from zirconia ceramic that was partially veneered with silica-based ceramic was inserted to replace tooth 22. Results: The young patient and her parents were very satisfied with the functional and esthetical results of the resin composite crowns after insertion. Oral hygiene measures were demonstrated, and could be easily realized by the girl. Since only a few clinical studies are available, the clinical longevity of permanent restorations fabricated from indirect resin composite has not yet been proven. In this case report, indirect resin composites were used to achieve esthetically and functionally pleasing results treating conical teeth.

RESUMEN

The aim of this study was to compare the clinical properties of tooth-colored computer-aided design/computer-aided manufacturing (CAD/CAM) materials for the fabrication of a 3-unit fixed dental prostheses (FDPs) in the same clinical scenario. A 53-year-old female patient was supplied with a 3-unit FDP to replace a second premolar in the upper jaw. Restorations were fabricated from 3 mol%, 4 mol%, and 5 mol% yttrium oxide zirconia, zirconia with translucency gradient, indirect composite resin, polyetheretherketone (PEEK), and polyetherketoneketone (PEKK). Milling time, weight, and radiopacity were investigated. Esthetics were examined following the US Public Health Service criteria (USPHS). The milling time for zirconia was twice as high as for the indirect composite resin, PEEK, or PEKK. The latter materials had a weight of 2 g each, while zirconia restorations yielded 5 g. Zirconia presented intense radiopacity. PEEK and PEKK required veneering and an opaquer was applied to the PEKK framework. All FDPs showed acceptable esthetics. PEEK and PEKK restorations were featured by a grayish shimmering. A variety of CAD/CAM materials are available to fabricate 3-unit FDPs with esthetically acceptable results. In the esthetic zone, PEEK and PEKK require veneering and an opaquer might be applied. Milling time, weight, and radiopacity were relatively high for zirconia FDPs.

RESUMEN

INTRODUCTION: Competencies in the clinical examination of patients with temporomandibular disorders (TMD) can be achieved by self-instruction. This study aimed to identify the impact of the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) instructional video on the practical examination skills of undergraduate students. MATERIALS AND METHODS: One week prior to completing an objective structured clinical examination (OSCE) addressing the examination of patients with TMD, undergraduate students in their third year received either the DC/TMD manual (control group) or additionally watched the instructional video once (intervention group). After passing the OSCE, a feedback questionnaire was completed by the students. RESULT: Fifty undergraduates were recruited to take part in the OSCE prior to their first clinical course. The sum scores achieved in the stations were higher in the intervention group, but missed significance. Participants of the intervention group more often agreed that completing the OSCE stations was easy, which was significant for one station (P = .023). 95.8% of the participating students supported the implementation of the video in dental education. DISCUSSION: Due to the conception of the study, the video was only presented once to ensure that the control group had no access to the medium at all. However, it might be interesting to investigate whether repeated watching of the video enhances its effect. CONCLUSIONS: Clinical competencies in the examination of TMD patients can be achieved by self-instruction with the DC/TMD manual and instructional video. Watching the video for educational purposes was highly recommended by undergraduate students.

RESUMEN

BACKGROUND: The etiology of temporomandibular disorders (TMD) can be explained on the basis of a biopsychosocial model. However, psychosocial assessment is challenging in daily dental practice. The purpose of the current study was to field-test the practicability of a novel psychosocial assessment scoring form regarding the reliability of scoring procedures and the opinion of examiners. The working hypotheses were that the scoring results of inexperienced undergraduate students were similar to the results collected by a gold standard and that the scoring form was easy to use. METHODS: A psychosocial assessment scoring form was developed in accordance with guidelines of the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD), including results of the Graded Chronic Pain Scale (GCPS), Patient Health Questionnaires (PHQ), and Generalized Anxiety Disorders (GAD). Inexperienced operators (undergraduate students) examined patients with TMD-associated complaints and rated the practicability of the scoring form. The scoring results were recalculated by two experienced operators and a consensus was defined as a gold standard. Reliability coefficients were determined comparing results of the gold standard and the inexperienced operators. RESULTS: Sixty-five examiners used the scoring form to obtain results for patients with TMD-associated complaints. Of the patients, 78.8% received a diagnosis according to DC/TMD decision trees. Two-thirds of the operators (62.9%) stated that the form was easy to complete, and 83.0% would use it in their dental practice. The reliability coefficients ranged between 0.81-1.00. CONCLUSIONS: Within the limitations of the present study, the psychosocial assessment scoring form seems to be an easy-to-use and practicable tool. The vast majority of the inexperienced examiners recommended the application.

RESUMEN

Perception of tooth shades is subjective and not rated exactly the same by different individuals. In terms of dental esthetics, chairside individualization of dental restorations might help to improve patient satisfaction. This investigation aimed to validate the practicability of a chairside approach for staining resin-based composite restorations. Thirteen inexperienced and 13 experienced participants were recruited to first individualize two CAD/CAM resin-based composite crowns in randomized order with light-curing characterization material using two reference crowns as templates. They then evaluated the characterization procedure. The processing times were recorded, and the clinical quality of the individualized crowns was evaluated by two blinded master dental technicians. Of the 52 crowns examined, 90.4% were assessed as suitable for insertion; there was no difference in quality attributable to the different degrees of experience of the operators. The average time required for characterization of the second crown was significantly shorter than for the first crown (30.9/43.0 min), indicating that the procedure can be implemented using a chairside approach. Among the operators, 80.8% said they would use the individualization technique and staining material again. Chairside staining of CAD/CAM resin-based composite restorations with light-curing characterization materials is practicable and can be recommended for both experienced and inexperienced users.

RESUMEN

Combined periodontal and prosthodontic treatment demands of patients require a structured coordination of pretreatments and an adequate choice of restorations. This is especially true if multiple teeth are missing and insufficient crown-root ratios are obvious. A 40-year-old patient with a severe periodontitis (Stage IV, Grade C) was treated with active, nonsurgical periodontal therapy. Afterwards, a supportive periodontal therapy was provided with a recall interval of three to four months. Due to a high tooth mobility of the anterior teeth in the upper jaw and a missing left canine, a combination of a resin composite (Signum composite, Kulzer, Hanau, Germany) and a unidirectional glass prepreg fiber (Tender Fiber Quattro, MICERIUM, Avegno, Italy) was utilized to fabricate a splint in a labside approach to stabilize the remaining teeth. Moreover, an artificial denture tooth was adhesively luted to the splint. A temporary polymer-based material (Vita CAD-Temp, VITA Zahnfabrik, Bad Säckingen, Germany) was selected to supply the posterior teeth of the patient with a 3-unit fixed dental prosthesis (FDP), and both restorations were adhesively cemented. 19 months after insertion, a fracture of the fiber-reinforced resin composite splint occurred that was intraorally repaired. In spite of the fracture of the splint, all materials were functionally and esthetically stable over the follow-up period of 22 months.

RESUMEN

Completely digital workflows for the fabrication of implant-supported removable restorations are not yet common in clinical dental practice. The aim of the current case report is to illustrate a reliable and comfortable workflow that reasonably merges conventional and digital workflows for the CAD/CAM-fabrication of implant-supported overdentures. The 53-year old patient was supplied with a digitally processed complete denture in the upper jaw and, simultaneously, with an overdenture supported by four interforaminal implants in the lower jaw. The overdenture included a completely digitally processed and manufactured alloy framework that had been fabricated by selective laser sintering. The case report indicates that digital manufacturing processes for extensive and complex removable restorations are possible. However, as it is currently not yet possible to digitally obtain functional impressions, future developments and innovations might focus on that issue.

RESUMEN

AIM: Verification of the interrater reliability of axis I diagnoses of the German version of the DC/TMD. The hypothesis was that the DC/TMD protocol yields comparable results, if examiner instructions are closely followed. MATERIAL AND METHODS: A culturally equivalent German translation of the DC/TMD was developed. During a 1-day calibration workshop at the University of Heidelberg, three examiners were trained by the DC/TMD Training and Calibration Center. According to the calibration guidelines, 16 models (11 cases, five non-cases) were examined by four experienced TMD specialists. Reliability was calculated with reference to the reference standard examiner as percentage agreement and kappa coefficients for DC/TMD diagnoses and intraclass correlation coefficients (ICCs) for findings. RESULTS: Excellent reliability was achieved for the diagnoses myalgia, myofascial pain with referral, arthralgia, headache attributed to TMD, disc displacement (DD) with reduction, DD without reduction without limited opening (κ = 0.85…1.00). Degenerative joint disease was diagnosed with substantial agreement (κ = 0.64), DD with reduction with intermittent locking and DD without reduction with limited opening were not present in our sample. Overall percentage agreement was 94%-100% for all diagnoses. CONCLUSION: The German version of the DC/TMD shows very good reliability and can be recommended for the use in clinical and research settings.

RESUMEN

Objectives: The aim of this project was to develop an instructional video that demonstrates a standardized clinical examination on patients with suspected temporomandibular disorders (TMD). After viewing the video, the learner should be knowledgeable about the examination steps and application of the examination techniques. Methods: The instructional video was created by two dentists who are experienced in assessing patients with suspected TMD. Additionally, both examiners were calibrated according to the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD). The instructional video was divided into chapters. Various camera angles, key points, image enlargements, and replays were used to better depict essential aspects of the assessment. Background noise was reduced to a minimum. Results: The instructional video was modified and completed in two phases: the first by an experienced dentist and the second by a dentist specialized in TMD. The final video includes nine chapters and is 26.5 minutes in length (https://doi.org/10.5061/dryad.k8r7qc1). Conclusion: Divided into chapters, this German instructional video shows an optimally timed, standardized clinical assessment of patients with suspected TMD.

RESUMEN

OBJECTIVES: This study aimed to survey dentists in Germany to identify their favored materials for the fabrication of tooth-supported single crowns (SCs) depending on the location of the abutment teeth and the preparation margin. MATERIALS AND METHODS: The survey included questions regarding demographic characteristics of dentists/their dental practice and preferred restorative materials for the fabrication of SCs for abutment teeth 16, 11, 34, and 36 with either supra- or subgingival preparation margins. RESULTS: Between August 2019 and February 2020, 721 dentists participated in the survey; responses from 33 dentists were excluded from data analysis because the dentists did not work in Germany or provided less than one fixed dental prosthesis/month. Dentists favored ceramic materials independent of the location of the abutment tooth and preparation margin (56.6-92.2%). CAD/CAM resin composites or full metals were preferred by only a few participants. A significantly higher proportion of dentists recommended porcelain fused to metal for subgingival preparation margins than for supragingival margins (p < 0.001). Characteristics of dentists/dental practices influenced a single scenario (11 subgingival) that was dependent on the dentist's time since graduation. When asked to specify the ceramic materials, numerous participants wrote a free response (5.7-7.8%) or did not answer (0.7-4.8%). CONCLUSIONS: Dentists in Germany selected restorative materials for SCs depending on the clinical scenario. Since numerous dentists did not specify the ceramic materials, postgraduate information and education might help to extend expertise. CLINICAL RELEVANCE: The results of this survey provide insight into the favored materials of dentists for the fabrication of tooth-supported SCs.

RESUMEN

PURPOSE: The aim of the current study was to analyze treatment concepts of a cohort of German dentists for planning, fabrication, and maintenance of implant-supported fixed and removable restorations. MATERIALS AND METHODS: A questionnaire including queries about experiences with implant-supported restorations as well as prosthetic and maintenance treatment concepts for supplying patients with fixed and removable implant-supported prosthetic restorations was developed and sent to 350 dental offices registered in the municipal area of Leipzig, Germany. RESULTS: An overall total of 62 returned questionnaires were included in the analyses, which relates to a response rate of 17.7%. Participating dentists were more involved in the prosthetic aspects of implant dentistry rather than surgery, while prosthetic concepts such as backward planning, digital processing, and application of all-ceramic materials were not commonly performed. Simple attachments were preferred over complex retention systems in removable implant-supported restorations. Tooth/implant-supported fixed denture prostheses as well as removable denture prostheses with supporting posterior implants were not regarded as a favorable treatment option. CONCLUSION: Within the limitations of the study, the data indicate that dentists favor simple and conventional treatment approaches in implant prosthetics. Prosthetic aspects in the planning of implant-supported restorations are often neglected. Prosthetic treatment guidelines and aspects should commonly be considered in the planning phase of implant-supported prosthetic restorations, and awareness should be increased in postgraduate education.

RESUMEN

PURPOSE: This analysis focused on periodontal health in shortened dental arches (SDAs). METHODS: In a randomized controlled clinical trial, patients with missing molars in one jaw and at least one premolar and canine on both sides were eligible for participation. In the partial removable dental prosthesis (PRDP) group (n = 79), molars were replaced with a precision attachment retained PRDP. In the SDA group (n == 71), the SDA up to the second premolars was either left as is or restored with fixed dental prostheses. Outcome variables were vertical clinical attachment loss (CAL-V), pocket probing depth (PPD), bleeding on probing (BOP) and plaque index (PLI). For CAL-V and PPD, the changes at six measuring points per tooth were analyzed. For BOP and PLI, patient related rates were calculated for each point in time. Statistical methods included linear regression analyses. RESULTS: In the intention-to-treat (ITT) analysis for CAL-V in the study jaw, the 10 year patient related mean changes were 0.66 mm in the PRDP group and -0.13 mm in the SDA group. The resulting mean patient related group difference of 0.79 mm (95% CI: 0.20 mm-1.38 mm) was significant (p = 0.01). There were no significant differences in the ITT analyses for PPD. For BOP and PLI, significant group differences with more favorable results for the SDA group were found. CONCLUSIONS: In view of lacking substantial differences for CAL-V and PPD, the overall differences were considered of minor clinical relevance. The results add confirmatory evidence to the shortened dental arch concept and its clinical viability (controlled-trials.com ISRCTN97265367).

RESUMEN

BACKGROUND: Prevalence values for symptoms and signs of temporomandibular disorders (TMD) in adolescents vary within the literature due to differences in set-ups of examination protocols. OBJECTIVES: The objective was to present prevalence values for symptoms and signs of TMD in German adolescents that were observed within a standardised examination. Prevalence values comparing gender or pubertal status should be investigated. METHODS: A cross-sectional sample of the LIFE Child Study aged 10 to 18 was examined. A questionnaire gathering anamnestic symptoms of TMD was completed, and an examination according to the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) was performed by trained dentists. Pubertal status according to Tanner stages was documented. Descriptive statistics, Mann-Whitney U and Wilcoxon signed-rank tests were performed. RESULTS: A total of 1.116 participants (mean age 12.9 years, 51.4% female) were consecutively recruited. Most prevalent anamnestic symptoms were headaches (55.7%) and temporomandibular joint (TMJ) sounds (17.6%). The major clinical sign was TMJ sounds (31.9%). Both the examination of muscles or TMJs showed that pain to palpation was statistically significantly higher than familiar pain (P < .001). Gender comparisons revealed higher prevalence values and an increase in TMD symptoms and signs during pubertal development in females. CONCLUSION: The prevalence of self-reported headaches, as well as anamnestic and clinical TMJ sounds, was high in German adolescents. Prevalence values for pain to palpation and familiar pain obtained relevant differences. Considering the DC/TMD, females are more affected by TMD signs and symptoms that increase during pubertal development, than male adolescents.

RESUMEN

OBJECTIVES: The aim of this study was to analyse the impact of different clinical conditioning approaches and an ammonium polyfluoride- and trimethoxysilylpropyl methacrylate-based experimental primer for intraoral luting of buccal tubes on silica-based ceramic surfaces. MATERIALS AND METHODS: A total of 60 leucite-reinforced glass ceramic molar crowns were conditioned using different methods (n = 10): I-roughening, hydrofluoric acid, silane; II-roughening, silane; III-roughening, experimental coupling agent; IV-experimental coupling agent; V-roughening; VI-no treatment. A buccal tube was adhesively luted to the ceramic surface. Subsequently, water storage, thermocycling and chewing simulation were carried out. The shear bond strength (SBS) was determined, and changes in the surface were assessed. RESULTS: All tubes of the control group (group VI) debonded after incubation. The conditioning methods using coupling agents revealed mean values for SBS of 61.56 MPa (group I), 45.53 MPa (group III), 41.65 MPa (group II), and 23.14 MPa (group IV). In groups I-III, both composite residues and cracks/tear-outs were detected. CONCLUSIONS: The conditioning of silicate ceramic surfaces with a suitable coupling agent system appears to allow sufficient adhesive luting of buccal tubes. The intraoral luting of fixed appliance elements on silicate ceramic surfaces using an ammonium polyfluoride- and trimethoxysilylpropyl methacrylate-based ceramic primer can withstand orthodontic forces. CLINICAL RELEVANCE: Ammonium polyfluoride- and trimethoxysilylpropyl methacrylate-based ceramic primers revealed promising results for the intraoral adhesive luting of orthodontic devices to silica-based ceramic crowns.

RESUMEN

Purpose: To survey dentists in Germany regarding their preferred cementation regimen for fixed dental prostheses (FDPs) fabricated from various restorative materials. Materials and Methods: An online survey was developed for completion by dentists in Germany between 08/2019 and 02/2020. The questionnaire gathered information about the cementation regimen (conventional, including the acid-base cements zinc-oxide phosphate or any glass-ionomer cement; self-adhesive; adhesive; don't know) that the participant would preferably select for the insertion of single- or multi-unit FDPs fabricated from various restorative materials. Data were also collected on demographic and personal characteristics. Results: A total of 721 dentists completed the survey, and the data from 688 questionnaires were included in the analysis. Conventional cementation was the option of choice for restorations fabricated from alloy/porcelain-fusedto- metal among 91.0% of the participants and for restorations fabricated from polycrystalline ceramics among 42.9% of the participants. Adhesive cementation was preferred for restorations fabricated from feldspathic/leucitereinforced glass ceramics (77.9%), lithium-disilicate glass ceramics (67.5%), zirconia-reinforced lithium-silicate glass ceramics (42.0%), and CAD/CAM resin composites (63.8%). Uncertainties regarding the appropriate cementation protocol for restorations fabricated from CAD/CAM resin composites were reported by 15% of the participants. More than 20% of the participants selected a technique that is less or not at all recommended for the cementation of restorations fabricated from zirconia-reinforced lithium-silicate glass ceramic and CAD/CAM resin composites. Conclusion: The results of the survey suggest that dentists in Germany select the cementation regime depending on the restorative material. Some of the participating dentists selected cementation regimens that are less or not at all recommended for restorations fabricated from zirconia-reinforced lithium-silicate glass ceramic and CAD/CAM resin composites, or were not sure about the appropriate cementation protocol.

RESUMEN

PURPOSE: To investigate changes in oral health prior to and after conversion of fractured abutment teeth in double crown-retained removable dental protheses (DC-RDPs) into root-anchored ball attachments. MATERIALS AND METHODS: Twenty patients were supplied with one root-anchored ball attachment after abutment tooth fracture. The Oral Health Impact Profile (OHIP-49) was completed by the patients prior to and after treatment to assess changes in perceived oral health. RESULTS: Changes in OHIP were statistically and clinically significant (28.90 points prior to treatment and 13.80 points after treatment), especially in cases with a minor number of remaining double crowns. CONCLUSION: The conversion of fractured abutment teeth in DC-RDPs into root-anchored ball attachments can be an effective strategy for improving perceived oral health.

RESUMEN

AIM: The aim of this study was to identify the influence of dental fear, pain, and impaired oral health-related quality of life (OHRQoL) on patients seeking care in a German emergency dental service. MATERIALS AND METHODS: Patients attending the emergency dental service at the University of Leipzig (Germany) were consecutively recruited and completed three questionnaires, including a visual analog scale for pain, the dental fear survey (DFS), and the oral health impact profile (OHIP-49). RESULTS: A total of 307 patients attended the emergency dental service and 286 agreed to take part in the study. The mean age was 41.7 years (50.4% males). The pain was reported by 87.2 % of the subjects, and their main reason for seeking care was a toothache (52.6 %). Regarding psychosocial characteristics, the mean OHIP and DFS scores were 40.0 and 47.6, respectively. For dentally fearful patients, a significantly higher impairment of OHRQoL was identified than for subjects with less or no fear. 33.2% of the participants irregularly consulted a dentist, and 58.4% of these patients were categorized as dentally fearful. CONCLUSION: The current investigation identified a high pain intensity as well as a high prevalence of dental fear, and a high impairment of OHRQoL in patients seeking care in an emergency dental service. CLINICAL SIGNIFICANCE: The results of the current study might help to develop specific services for patients with dental fear, which can successively reduce the number of emergency dental treatments.

RESUMEN

OBJECTIVE: Valid and reliable recording is a key requirement for accurately simulating individual jaw movements. METHODS: Horizontal condylar inclination (HCI) and Bennett's angle were measured using a digital jaw tracker (Cadiax® Compact 2) in 27 young adults. Three mounting methods (paraocclusal tray adapter, periocclusal tray adapter, and tray adapter with mandibular clamp) were tested. RESULTS: The mean values of the HCI differed by up to 10° between the mounting methods; however, the values for Bennett's angle did not differ substantially. While the intersession reliability of the Bennett's angle assessment did not depend on the mounting method, the reliability of the HCI assessment was only fair to good for the paraocclusal mounting method but poor for both periocclusal mounting methods. DISCUSSION: For attaching the tracing bow of jaw trackers to the mandible, a paraocclusal tray adapter should be applied, to achieve the most reliable results.

RESUMEN

OBJECTIVE: This study determines the effect of temporomandibular disorders (TMD) on the reliability of mandibular movement assessments. METHODS: The vertical and horizontal jaw movements, as well as overjet and overbite, were measured twice in 56 consecutively recruited adult subjects with TMD according to the RDC/TMD and 29 controls without TMD diagnosis by experienced dentists utilizing a millimeter ruler. The reliability was determined by intraclass correlation coefficient (ICC). RESULTS: Neither statistically nor clinically relevant differences in the repeatability between both subgroups could be detected (all p ≥ 0.077). The mouth opening and overjet proved an excellent reliability (ICC 0.85-0.92). Overbite and laterotrusion showed good to excellent reliable results (ICC 0.74-0.82). The second measurement of the vertical jaw movement resulted in systematically higher values (p < 0.003). DISCUSSION: The assessment of the mandibular movement with a millimeter ruler is a reliable procedure irrespective of TMD. To decrease the variances in the mouth opening measurements, the patient should be asked beforehand to practice this movement.
