Abstract
Disabled persons' chairside dentistry is challenging. We aimed for a retrospective breakdown of dental services delivered to disabled patients by dental students and to discuss feasibility of a chairside approach. Consecutive patients, who received scheduled dental treatment by dental students from 2002 to 2021, were included. Demographic data, medical diagnoses, number of treatment sessions, performed treatments, and treatment break-offs were collected and analyzed with descriptive statistics. In total, 224 individuals with various disabilities (mean age 36.4 ± 14.6 years) received dental services in 2282 sessions altogether (10.3 ± 11. sessions per patient). Professional tooth cleaning was the most frequently provided treatment (55.8% of sessions). A total of 654 teeth were restored with fillings, 97 teeth were extracted, 56 teeth had endodontic treatment, and 25 removable dentures were fitted. Treatment break-off due to incompliance and referral to dental general anesthesia occurred in 74 patients (33%). Chairside treatment of disabled persons by dental students is feasible in many cases. Our study may serve as an incentive for clinicians/researchers to report on treatment modalities and outcomes of chairside dentistry in patients with special oral health care needs, preferably by the use of prospective study designs, to contribute data and strategies in the fight for control of oral health inadequacies.

Abstract
OBJECTIVES This in vitro study aimed to evaluate the wear of natural teeth opposing 3 mol% yttria-stabilized tetragonal zirconia polycrystal (3Y-TZP) with different surface conditions. MATERIALS AND METHODS Sixty 3Y-TZP specimens were randomly assigned to six groups (n = 10), differing in surface condition. In three groups, the samples underwent glazing-with the glaze applied to roughened (i.e., 106-µm-grit diamond-finished), as-sintered, and polished zirconia. The three remaining groups consisted of unglazed specimens: solely polished samples and diamond-finished samples (106-µm-grit and 46-µm-grit) without further conditioning. Two-body wear was evaluated at extracted, non-carious molars (n = 60), which served as antagonists in chewing simulation (10,000 masticatory cycles, 49N load). As a control, natural teeth with intact enamel surfaces were tested against natural molars (n = 10). All samples were 3D-scanned before and after the chewing simulation (7 Series, Straumann). Volume loss was calculated (Inspect Software, GOM), and statistically analyzed (SPSS Statistics 24, IBM). RESULTS Volume loss of the natural antagonists decreased in the following order: 106-µm-grit diamond-finished zirconia (4.6 ± 2.5 mm3), glazed 106-µm-grit diamond-finished zirconia (3.8 ± 1.1 mm3), glazed as-sintered zirconia (3.5 ± 0.9 mm3), 46-µm-grit diamond-finished zirconia (1.7 ± 0.6 mm3), control (1.6 ± 0.7 mm3), glazed polished zirconia (1.4 ± 0.5 mm3), and solely polishing (0.4 ± 0.2 mm3). Even when polishing the surfaces before glazing, volume loss was not mitigated to the same extent as after polishing alone. CONCLUSIONS The zirconia surface condition beneath the glazing influences antagonist wear. Although polishing before glazing resulted in acceptable levels of antagonist wear, this approach did not yield as favorable results as polishing alone. CLINICAL RELEVANCE For operators favoring glazing, pre-polishing the zirconia surface could be advantageous to reduce wear.

Abstract
OBJECTIVES Due to the growing popularity of body modifications, dental practitioners are increasingly confronted with oral piercing and its implications. Successful consultation and subsequent change of patient behavior require an understanding of the patient's personality and the deep reasons that explain this self-injurious behavior. This is the first study evaluating personality traits and aspects of body perception in a cohort of adults with oral piercing. METHOD AND MATERIALS Sixty-two individuals with labial and/or tongue piercing completed three validated questionnaires assessing body perception and personality traits (Questionnaire for assessing one's own body; Sensation Seeking Scale; Big Five Inventory Scale). Fisher Exact probability test and Mann-Whitney U test were used to determine differences in frequency data and in psychologic parameters between subgroups. RESULTS Eighteen single- and 44 multiple-pierced individuals completed the study (53 women, 9 men). The odds for being multiple pierced was significantly higher for tongue than for labial piercing (3.89 and 0.63, respectively; P = .003). In all psychologic parameters measured, the sample showed score distributions within reference norms. However, multiple-pierced individuals displayed a significantly lesser feeling of attractiveness, less self-confidence, and more uncertainty/anxiety towards their body than single-pierced probands (P < .05). CONCLUSION Psychologic characteristics of individuals with oral piercing do not fundamentally differ from those of the average population. Therefore, dental practitioners should focus on the medical and dental implications of oral piercing in the counseling of patients who have or intend to have such done.

Abstract
Background: Medication-related osteonecrosis of the jaw (MRONJ) is a potentially severe complication of mainly antiresorptive drugs. We evaluated the frequency of dentoalveolar pathologies in patients scheduled for antiresorptive therapy in a 'real-world' setting, also including patients with poor oral health potentially requiring tooth extractions and/or other dentoalveolar surgery. This approach is in contrast to the setting of recent randomized trials with restrictive exclusion criteria. Patients & methods: We prospectively included patients suffering from solid tumors with osseous metastases or multiple myeloma. Screening for dentoalveolar pathologies was done prior to initiation of antiresorptive therapy at the specialized MRONJ clinic of the University Hospital for Cranio-Maxillofacial and Oral Surgery, Innsbruck, Austria. Results: 119 subjects could be included. In 76 patients (63.9%), a dental focus was revealed including deep caries (24.4% of patients), chronic apical periodontitis (26.9%), periodontal disease (45.8%), root remnants (16%), jaw cysts (2.5%), partially impacted teeth (5.0%) and peri-implantitis (5.0%). Conclusion: Considering the high number of dentoalveolar pathologies (63.9%), systematic dental focus screening prior to initiation of antiresorptive therapy is of utmost importance to lower the risk for MRONJ.

Abstract
The aim of this study was to investigate the operating conditions of dentists in Central Europe during the first coronavirus disease 2019 (COVID-19) lockdown. A survey including 24 questions was emailed to dentists in Austria, Germany, Switzerland and South Tyrol (Italy). Questions regarding dentists’ field of work, working hours, treatments performed, personal protective equipment and protocols, and economic consequences were asked. 1731 participants were included. 30.4% of participants worked mainly in Austria, 60.8% in Germany, 6% in Switzerland and 2.1% in South Tyrol. A country-specific analysis for the situation of South Tyrol was not possible due to the low participation; 53.7% of German, 45.5% of Austrian, and 11.7% of Swiss respondents reduced their working hours; 42.8% of Austrian, 41.5% of Swiss, and 17.3% of German participants closed their offices temporarily; 52.2% of respondents provided emergency service including pain management, restorations/temporaries, and denture repairs. A lack of access to FFP2/FFP3 (filtering facepiece) respirators was indicated by 59.4% Austrian, 38.0% German, and 11.7% Swiss dentists (p < 0.001). FFP2/FFP3 respirators were, when available, most frequently used in Austria (86.9%), followed by Switzerland (61.2%) and Germany (56.7%) (p < 0.001). Financial consequences could not be conclusively quantified by 58.6% of the participants. Most respondents in all partaking countries made use of governmental support. A lack of blueprints/guidelines resulted in heterogeneous working conditions. In consideration of a potentially high risk of infection in the dental setting, non-emergency dental treatments were largely suspended in all participating countries.

Abstract
Papillon-Lefèvre syndrome (PLS) is a rare autosomal recessive genodermatosis characterized by palmoplantar keratoderma and severe periodontitis leading to premature loss of primary and permanent teeth. PLS is caused by loss-of-function mutations in CTSC, lacking functional cathepsin C, which impairs the activation of neutrophil serine proteases. Precise pathogenesis of periodontal damage is unknown. Patient 1 presented with well-demarcated, transgredient, diffuse, palmoplantar keratoderma and psoriasiform lesions from the age of 2 years. Based on severe and recurrent periodontal inflammation, his dentist had diagnosed PLS at the age of 3 years and provided a strict oral hygiene regimen with repeated adjunct antibiotic therapies. Oral acitretin 10 mg/day along with tretinoin ointment at the age of 9 greatly improved palmoplantar keratoderma. Aged 18 years, the patient exhibited an intact permanent dentition and absence of periodontal disease. Patient 2, a 30-year-old man, suffered from transgredient, diffuse, palmoplantar keratoderma with fissuring from the age of 2 months, marked psoriasiform plaques on elbows and knees, and nail dystrophy. Intriguingly, without specific dental treatment, teeth and dental records were unremarkable. He was referred with a suspected diagnosis of psoriasis. Both patients were otherwise healthy, blood tests and sonography of internal organs were within normal limits. Panel sequencing revealed loss-of-function mutations in CTSC, c.322A>T (p.Lys108Ter) and c.504C>G (p.Tyr168Ter) in patient 1 and homozygous c.415G>T (p.Gly139Ter) in patient 2. The final diagnosis of unusual PLS was made. PLS should be considered in palmoplantar keratoderma lacking periodontitis or tooth loss.

Abstract
AIM The aim of this retrospective study was to determine the prevalence of caries and treatment needs in the collective of patients ?16 years of age, who underwent scheduled dental general anaesthesia (DGA) at the University Clinic of Innsbruck from January 2015 to June 2019, with respect to demographic factors. MATERIALS AND METHODS A retrospective analysis of children's diagnoses, demographics, and dental treatment under general anaesthesia in Innsbruck, Austria, from 2015 to 2019 was performed. Anonymised demographic data (age; gender; the presence or absence of general disease or disablement; parents' first language (German- (GS) or non-German-speaking (non-GS), reflecting ethnicity; and the number of teeth restored and extracted under DGA were collected from patients' files. Data was analysed by means of descriptive and comparative statistics. RESULTS The main group consisted of 545 subjects at a median age of 5.3 (IQR 4.4-6.6) years, who had exclusively primary teeth and or first molars that received restorations or were extracted. Of the subjects, 84.4% were classified with uncooperativeness due to dental anxiety and 15.6% with systemic diseases or intellectual and or physical disablement. In this group, 47.9% were GS and 52.1% were non-GS or had GS or non- GS parents. In the total sample, 5 (IQR 3-7) primary teeth were restored and 4 (IQR 4-7) extracted. Subgroup analysis revealed statistically significant differences in the number of extracted primary teeth between children with and without systemic diseases or disablement - 3 (IQR 1-5) versus 4 (IQR 2-7) - and between children of GS and non-GS parents - 4 (IQR 2-6) versus 5 (IQR 3-7.8). Zero (IQR 0-0) first molars were filled and extracted. CONCLUSION Within the study collective of children in poor oral health, the offspring of non-GS families were overrepresented (compared to their prevalence in the total population) and displayed a higher prevalence of deep caries than those of GS parents. By intensifying and special gearing of prophylactic measures to the non-GS population and promoting the parents' insight into the importance of oral hygiene and regular dental attendance, the demand for scheduled DGA might be greatly reduced. In the small share of children who suffer from severe diseases or disablement and are thus unable to cooperate with home care or dental treatment, DGA will remain the treatment of choice.

Abstract
Objectives To compare the cleansing efficacy of a representative “ten seconds” auto-cleaning device with that of uninstructed manual toothbrushing in a pilot study. Materials and methods Twenty periodontally healthy probands refrained from oral hygiene for 3 days. Baseline full-mouth plaque scores (Rustogi Modified Navy Plaque Index, RMNPI) were assessed. After randomization, probands cleaned their teeth either with the auto-cleaning test device according to the manufacturer’s protocol or with a manual toothbrush. Plaque reduction was assessed by two aligned blinded investigators. After a 2-week recovery, the clinical investigation was repeated in a crossover design. The brushing pattern of the auto-cleaning device was analyzed in probands’ casts. Results Full-mouth plaque reduction was 11.37 ± 3.70% for the auto-cleaning device and 31.39 ± 5.27% for manual toothbrushing (p < 0.0001). The investigation of the auto-cleaning device’s brushing pattern in dental casts revealed a positive relationship of bristle rows in contact with tooth surfaces and the cleansing efficacy in the respective areas. A maximum of 2/4 bristle rows were in contact with the tooth surfaces; in some areas, the bristles had no contact to the teeth. Conclusions Uninstructed manual toothbrushing is superior to auto-cleaning. The alignment and density of the auto-cleaning device’s bristle rows need to be improved, and assorted sizes would be necessary to cover different jaw shapes. Clinical relevance The auto-cleaning device has been developed to accommodate individuals with poor dexterity or compliance. To date, it is unable to provide sufficient plaque reduction due to an inappropriate bristle alignment and poor fit with diverse dental arches.

Abstract
AIM The aim of this study was the assessment of prevalence, distribution, and treatment of deep caries and odontogenic abscess formation in children who received emergency dental general anaesthesia (DGA) at the University Hospital of Cranio-Maxillofacial and Oral Surgery of Innsbruck, Austria. MATERIALS AND METHODS The study population was composed of 1,184 consecutive cases of emergency DGA from January 2008 to June 2014, in patients ?16 years who had presented with odontogenic pain and/or swelling. Under DGA, the tooth causative for the acute pain, and all teeth with deep caries had been routinely removed. From patient files, demographic data, abscess location and therapy, and the number of teeth extracted under DGA were recorded and analysed by means of descriptive statistics. RESULTS In 549 cases (46.4%) (mean age 5.29±2.39 years), an abscess formation was recorded; 90.5% of all abscesses were submucous, and 9.5% affected fascial spaces. Decayed primary molars and maxillary primary incisors and canines were most often causative for abscess formation. Drainage was in most cases performed by tooth extraction with/without an intraoral incision under antibiotic therapy. Per case, a mean of 5.91±4.04 primary teeth were extracted. In 77 individuals (mean age 9.83± 2.59), a mean of 1.92±1.02 permanent first molars were extracted. CONCLUSION In the study population, prevalence of deep caries and abscess formation was alarmingly high. In consideration of the medical risks and high efforts immanent in DGA, educational measures should address parents in order to raise awareness of their responsibility for their children´s health.

Abstract
OBJECTIVE To compare the cleansing efficacy of waist-shaped versus cylindric inter-dental brushes in patients receiving supportive periodontal therapy. MATERIALS AND METHODS After sample size estimation, 20 periodontal maintenance patients diagnosed with periodontitis stage 3 were recruited. Brushing efficacy of waist-shaped and cylindric inter-dental brushes was evaluated in a randomized-controlled, examiner-blinded, two-period crossover study by assessment of the Turesky modification of Quigley-Hein plaque index (T-QHI) and the papillary bleeding index (PBI) at four sites per tooth. RESULTS Seventeen probands with 1,474 tooth sites finished the study. At baseline, median of overall T-QHI scores was 1.4 (interquartile range 1.38-1.92). After 1 month, T-QHI for waist-shaped inter-dental brushes was 1.24 (1.03-1.52); in 15 individuals, T-QHI 0 was the grade most often measured. T-QHI for cylindric brushes was 1.71 (1.18-2.29; p = .042), with T-QHI 0 being the grade most often measured only in seven individuals. The odds ratio for establishing plaque-free inter-dental sites with waist-shaped relative to cylindric brushes was 1.8 [95% CI 1.6-1.9] (p < .001; logistic regression analysis). There were no statistically significant differences between PBI levels of waist-shaped and cylindric brushes. CONCLUSION This study has demonstrated the superiority in cleansing efficacy of waist-shaped over cylindric inter-dental brushes in individuals receiving supportive periodontal treatment.

Abstract
Objective: To estimate whether outcomes at 12-month follow-up may be predicted by an intermediate and early response to a 3 mm resilient splint therapy for unilateral arthralgia and myofascial pain assessed at 3- and 6-month follow-ups. Methods: Data obtained from one retrospective cohort study consisting of 78 patients suffering from chronic and sub-acute unilateral arthralgia and myofascial pain who were managed with 3 mm resilient splint therapy were subjected to analysis. Results: Baseline visual analog scale (VAS) intensity, gender as well as changes in the intensity of VAS pain at 3- and 6-month follow-ups predicted unilateral arthralgia and myofascial pain group membership (p < .001). The function classified 83.3% of the cross-validated and 87.2% of original grouped cases correctly. Discussion: The proposed model may be used to timely identify patients who are at risk of developing prolonged non-responsive unilateral arthralgia and myofascial pain chronicity.

Abstract
OBJECTIVES Special needs patients are prone to insufficient oral care and subsequent caries or periodontitis. The aim of this retrospective study was the assessment of demand for restorative therapy and tooth extractions under general anesthesia in adults with intellectual and/or physical disablement (IPD) or psychiatric disorders (PDs) with inherent dentist phobia at the University Hospital of Innsbruck with regard to demographic factors. MATERIALS AND METHODS A total of 444 consecutive cases of scheduled dental general anesthesia (DGA) in adults from 2003 to 2014 were included. From patient files, demographic data, the presence of either IPD or a PD, attested by a mandatory certificate, and restorative therapy and tooth extractions performed under DGA were obtained. Data analysis was carried out by means of descriptive and comparative statistics. RESULTS Four hundred two cases (mean age 37.5 ± 13.87 years) assigned to 283 individuals with IPD and 42 cases (mean age 36.09 ± 13.03 years) assigned to 39 individuals with PDs arose in the observed period. Patients with PDs required significantly more restorations (in 7.98 ± 5.4 versus 5.34 ± 4.41 teeth; p = 0.002; Mann-Whitney U test) and extractions (of 4.86 ± 4.51 versus 2.6 ± 3.96 teeth; p < 0.001; Mann-Whitney U test) than patients with IPD. CONCLUSIONS Demand for dental treatment was high in the collective of special needs patients. Oral health status was worse in patients with PDs than in patients suffering IPD. CLINICAL RELEVANCE While in patients with severe disablement, DGA presents the only treatment option, specific preventive programs should be implemented for patients with minor disablement or dentist phobia. In these patients, alternative approaches should be promoted.

Abstract
PURPOSE Various resin cements and priming agents are available for adhesive luting of zirconia restorations. The purpose of this study was to investigate how cement type and priming protocol affect the shear bond strength on zirconia ceramics. MATERIALS AND METHODS Yttria-stabilized tetragonal zirconia polycrystalline ceramic cylinders were bonded to flat zirconia ceramic surfaces using 7 commercially available resin cements. Ten specimens of each cement group were pretreated with a universal primer, and 10 specimens per group were bonded without pretreatment. In addition, 10 specimens per group were pretreated with system-specific zirconia primers, which were available for 3 cements. Altogether, 170 bonded specimens were water-stored, thermal-cycled, and then submitted to shear bond strength tests. The shear bond strength and the fracture types were documented. Differences in shear bond strengths were assessed using 2-way ANOVA with post-hoc test (α = 0.05). A point-biserial correlation was run between the fracture patterns and the shear bond strengths. RESULTS The mean shear bond strengths of cements in the unprimed group showed large variations between 2.52 ± 3.01 (mean ± SD) MPa and 33.15 ± 7.35 MPa. Pretreating the specimens with a universal primer improved the shear bond strengths significantly in all groups (p < 0.05) with a range of 21.80 ± 12.51 to 57.20 ± 11.40 MPa. The system-specific primers also improved the shear bond strength significantly, compared to the unprimed group (p < 0.01); however, only one system-specific primer achieved a shear bond strength superior to the universal primer (p < 0.01). There was also a statistical correlation between the fracture type and the shear bond strength (p < 0.0005), with cohesively fractured specimens showing higher shear bond strengths (37.24 ± 19.87 MPa) than adhesively fractured specimens (23.10 ± 17.65 MPa) (p < 0.001). CONCLUSION Using universal primer can enhance the maximal shear bond strength of zirconia.

Abstract
Aim The aim of this study is to investigate the penetration abilities of a commercially available low-viscosity resin infiltrant into developmentally hypomineralized teeth in vitro. Materials and methods Four extracted third molars of a 17-year-old patient with signs of developmental enamel hypomineralization (discoloration, increased opacity, and surface roughness) were infiltrated with a low-viscosity resin mixed with a fluorescent dye, according to the manufacturer's standard protocol. Four extracted molars with sound enamel or showing only initial fissure caries were used as a control group. Specimens were embedded in polymethylmethacrylate, and grindings were prepared. High-resolution projectional radiography of the grindings was performed, and, for one specimen, quantitative micro-computed tomography was used to measure hydroxyapatite density in enamel and dentin lesions. After decalcification, the grindings were examined by reflected bright-field microscopy, wide-field fluorescence microscopy, and confocal laser scanning microscopy. Fluorescence micrographs were superimposed on the radiographs and analyzed correlatively. Results The pattern of hypo-/demineralization in enamel and dentin in developmentally hypomineralized teeth showed a good congruence with the pattern of resin infiltration. Cavitations and dentin tubules up to a depth of 2 mm beyond cavitations were filled by the infiltrant. In control teeth, the penetration of the infiltrant was limited to decalcified enamel areas (initial fissure caries). Conclusions In vitro infiltration of developmentally hypomineralized enamel was successful. Clinical significance Resin infiltration might be considered as a routine procedure in the treatment of developmentally hypomineralized teeth. Further investigations with higher sample sizes, different degrees of severity, different stages of lesion extension, and modified treatment protocols are necessary.

Abstract
Background Dark pigmented lesions of the oral mucosa can represent a major diagnostic challenge. A biopsy is usually required to determine the nature of such intraoral discolorations. This study investigates the potential use of infrared spectroscopy for differential diagnosis of amalgam tattoos versus benign or malignant melanocytic neoplasms. Materials and methods For this retrospective study, formalin-fixed paraffin-embedded tissue (FFPE) specimens of dark pigmented lesions concerning the oral mucosa or the lip were investigated using mid infrared spectroscopy. The samples were chosen from patients who had undergone a mucosal biopsy at the University Hospital Innsbruck (Austria) between the years 2000 and 2017. Principal component analysis was used for data exploration. Evaluation was based on the superimposition of the recorded spectra and the corresponding histologic slides. Results In total, 22 FFPE specimens were analyzed. Clear differences were found between amalgam and non-amalgam samples. A general weakening of the penetrating infrared radiation allowed for unspecific discrimination between these two classes. An overall accuracy in predicting the correct class of 95.24% was achieved. Conclusion Infrared spectroscopy appears to be a suitable technique to differentiate between amalgam tattoos and melanocytic lesions in FFPE samples. It could potentially be applied in vivo, too, serving as a non-invasive diagnostic tool for intraoral dark pigmented lesions.

Abstract
OBJECTIVES To compare cone beam computed tomography (CBCT) and magnetic resonance tomography (MRT) in patients with temporomandibular joint (TMJ) arthralgia in respect of the evaluation of bony structures, and to correlate joint space distances measured in CBCT with the morphology and the position of the disc visualized in MRT. MATERIALS & METHODS 26 temporomandibular joints (TMJs) in 13 patients clinically diagnosed with TMJ arthralgia were examined by both CBCT and MRT. All images were evaluated by use of a form. The results were compared in regard of conformability of the diagnoses of osseous structures established by each imaging method. Anterior, superior and posterior joint space distances measured in CBCT-images were related to disc morphology and position visualized in MRT. RESULTS Conformability of CBCT and MRT in the evaluation of bony TMJ structures ranged from 69.3 to 96.6 %. Osseous alterations such as erosions, osteophytes and cysts detected by CBCT could partly not be discerned by MRT. The correlation of joint space distances with disc morphology (biconcave or not biconcave) was not statistically significant. The correlation of joint space distances and disc position was statistically significant only for the superior joint distance. CONCLUSION CBCT outclasses MRT in the visualization of osseous alterations, which are diacritic in the differentiation of simple arthralgia from osteoarthritis. Therefore, CBCT imaging is appropriate in patients clinically diagnosed with TMJ arthralgia.Superior joint space distance not being the highest joint space in sagittal CBCT indicates an anterior disc displacement.For the visualization of structural changes or displacement of the disc frequently associated with osseous changes, MRT is the optimal tool. Thus, the combination of the two imaging methods allows a comprehensive diagnosis in TMJ arthralgia patients.

Abstract
Hypohidrotic ectodermal dysplasia (HED) comprises a large group of inherited disorders of ectodermal structures, characterised by hypo- or anhidrosis, hypotrichosis and hypo- or oligo- or anodontia. We aimed to systematically assess the spectrum of prosthodontic approaches with regard to the patients' age and to provide clinical implications for practicing dentists. An electronic and manual search was conducted in four databases (Medline, LIVIVO, Cochrane Library, Web of Science Core Collection). Publications of multiple study designs written in English or German without data restrictions, reporting on prosthodontic treatment of patients diagnosed with HED and afflicted with oligo- or anodontia, were included. In total, 75 articles on 146 patients were analysed according to the patients' age. In children aged 2-17 years, removable full or partial (over)dentures represented standard treatment. In the mandible, implant-supported removable dentures on two interforaminal implants presented an alternative, already in young childhood. In cases with more than six teeth per jaw, also fixed (resin) bridges were used, frequently after orthodontic treatment. In adults, fixed or removable reconstructions with the help of up to eight implants per jaw, usually placed after bone augmentation procedures, were standard. Ten case reports/series with long-term follow-up illustrated the need for consistent maintenance including denture renewals. Prosthodontic rehabilitation should start in early childhood and needs to be revised in accordance with the patients' growth. Treatment should be carried out by a multidisciplinary team addressing variable demands in different age groups.

Abstract
PURPOSE To determine a possible association between asymptomatic temporomandibular joint (TMJ) condylar erosion and the number of missing posterior teeth and their location, as well as the number of dental quadrants with missing posterior teeth. MATERIALS AND METHODS This case-control study involved 210 patients (male to female ratio = 98:112) aged 16-74 years, with 105 asymptomatic patients with TMJ condylar erosion and a control group of 105 patients without TMJ condylar erosion. Cone beam computed tomography images were evaluated to classify the severity of TMJ condylar erosion as grade 0 (absence of erosion), grade I (slight erosion), grade II (moderate erosion), or grade III (extensive erosion). RESULTS The number of missing posterior teeth (mean ± standard deviation [SD]; 2.7 ± 2.4 vs 0.7 ± 1.2) (P < .001), number of dental quadrants with missing posterior teeth (1.5 ± 1.3 vs 0.6 ± 0.9) (P < .001), and bilateral location of missing posterior teeth (41 ± 39.0 vs 10 ± 9.5) (P < .001) were all significantly higher in patients with erosion than in those without erosion. The condylar erosion grade was significantly associated with the number of missing posterior teeth (odds ratio [OR] = 1.24; P = .006), the number of dental quadrants with missing posterior teeth (OR = 1.36; P = .006), and the bilateral occurrence of missing posterior teeth (OR = 3.03; P = .002). CONCLUSION The findings from this study suggest a possible association between TMJ condylar erosion grades and the number of missing posterior teeth, the number of quadrants with missing posterior teeth, and the bilateral occurrence of missing posterior teeth.

Abstract
AIMS To assess the association between chronic tension-type headache coexistent with chronic temporomandibular disorder (TMD) pain and severe limitations in physical and emotional functioning. METHODS Sample size estimation was used to determine that this case-control study should include 126 subjects. Subjects suffering from chronic TMD who were aged between 18 and 68 were recruited in routine clinical practice. Of the 126 included subjects, 63 had TMD pain associated with chronic tension-type headache (cases) and 63 had TMD pain without a history of tension-type headache (controls). Clinical diagnosis of TMD was made according to the Research Diagnostic Criteria for TMD (RDC/TMD) Axis I criteria, and clinical diagnosis of headache was made according to the International Classification of Headache (ICHD-II). RDC/TMD Axis II criteria were applied to record the scores from the Graded Chronic Pain Scale (GCPS) and the Symptoms Checklist-90-Revised Depression (SCL-DEP) and Somatization (SCL-SOM) scales. A logistic regression analysis was used to assess the relationship between TMD pain with chronic tension-type headache and high levels of depression and somatization severity as scored on the SCLDEP and SCL-SOM scales, respectively, and high pain-related disability (GCPS grade III or IV). Data were adjusted to take into account age, gender, time since TMD pain onset, chronic TMD pain intensity, and characteristic pain intensity. RESULTS The presence of chronic tension-type headache was significantly associated with severe SCL-DEP (odds ratio [OR] = 7.2; P < .001), severe SCLSOM (OR = 13.8; P < .001), and high pain-related disability (OR = 9.7; P < .001). CONCLUSION This study provides evidence of associations between the clinical diagnosis of chronic tension-type headache coexistent with chronic TMD pain and key aspects of physical and emotional functioning reflected in severe depression, severe somatization, and high pain-related disability.

Abstract
Dental aplasia of heterogenous etiology may cause jaw growth disturbance, malocclusion, esthetic discontent and psychosocial impairment. By a case report of a young patient suffering from hypodontia, class II malocclusion and a deep bite the intricate interdisciplinary diagnosis- and treatment-protocol targeting the functional and esthetic rehabilitation is illustrated.

Abstract
After a careful diagnosis, treatment planning and pretreatment, two partially edentulous patients were restored partly by onlays, crowns and bridges, partly by removable prostheses. According to esthetic and functional demands all- and/or metal-ceramic restorations were used as well as cast frame prostheses with clasps or extracoronal attachments.

Abstract
The prosthetic rehabilitation of two partially edentulous patients is presented: one Patient was restored by permanent crowns and bridges attached to natural teeth and to implants, the second was treated by crowns attached to natural teeth and removable implant- supported prostheses. Depending on esthetic requirements and the localization of preparation margins all- or metal-ceramics were used for single crowns, metal-ceramics was used for bridges. In general, a well coordinated cooperation of dentist, surgeon and dental technician in treatment planning and realization is required for a successful prosthetic rehabilitation.

Abstract
A study on the diagnostic value of the parotid and mixed saliva assay after stimulation with 1% pilocarpine hydrochloride was carried out in 36 controls and 26 patients affected with chronic pancreatitis. No statistical difference between the two groups was found as far as saliva volume, bicarbonate and amylase (concentration and output) are concerned. No correlation was found between the results of the saliva test and those of the secretin-pancreozymin test or endoscopic retrograde pancreatography. These data excluded any diagnostic role of the saliva test in chronic pancreatitis.
