Published: June 2007

Background:

Implantable cardioverter defibrillator (ICD) patients potentially face significant psychological distress because of their risk for life‐threatening arrhythmias and the occurrence of ICD shock.
Methods:

The purpose of this study was to test an ICD stress and shock management program delivered in either a six‐week format or a one‐day workshop format. This intervention was aimed at reducing psychological (anxiety) and physiological (salivary cortisol) markers of distress in ICD patients. Secondary endpoints included measures of quality of life (QOL) and patient acceptance of device therapy, as well as biological mediators of inflammation (TNFα and IL‐6).
Results:

The ICD stress and shock management program resulted in the reduction of anxiety (P < 0.05) and cortisol levels (P < 0.05) in both the six weekly sessions format and the one‐day workshop. Measures of anxiety decreased more rapidly with weekly intervention (P = 0.05). Both formats also resulted in a significant increase in patient acceptance of the ICD (P < 0.01). Follow‐up assessment from posttreatment (T2) to four‐month follow‐up (T4) indicated no significant change in depression scores from posttreatment for all groups taken together, but there was a significant group by time effect, such that the workshop group displayed an increase in depression scores from T2 (M = 8.71, SD = 4.39) to T4 (M = 13.57, SD = 11.90), P < 0.05.
Conclusions:

These results suggest that structured interventions for shocked ICD patients involving ICD education and cognitive‐behavioral strategies can reduce psychological distress and improve quality of life, regardless of format.

Published: June 2007

Background:

This acute feasibility study compared two different automatic capture detection methodologies, the reduced coupling capacitor (RCC) and the independent pace/sense (IPS) methods, for the left ventricle (LV).
Methods:

LV threshold tests were performed in DDD mode, with LV‐only and biventricular (BiV) pacing using an external cardiac resynchronization therapy (CRT) defibrillator. Evoked response (ER) signals from LV leads were recorded using the LVTip (LVTip→Can) and LVRing (LVRing→Can) to empty pulse generator (Can) housing sensing vectors to evaluate the two methodologies. Pacing vector, pulse duration, atrioventricular delay, and interventricular delay were varied to assess their effects on ER. The minimum ER amplitude (ERmin), signal‐to‐artifact ratio (SAR), and ER amplitude voltage dependence were evaluated. ERmin>2 mV and SARmin>2 define potential automatic LV capture detection for the two methodologies.
Results:

Data collected from 43 patients (63.7 ± 11.0 years) were analyzed, including unipolar and bipolar (14/29) LV leads. Neither ER sensing method was affected by changing the pacing vector. The LVTip→Can ERmin was significantly decreased at the 1.0‐ms pulse duration when compared to 0.4‐ms (p < 0.05). During BiV pacing, LVTip→Can ERmin increased at negative interventricular delays and decreased at positive interventricular delays relative to simultaneous pacing. LVTip→Can resulted in fewer patients with sufficient ER characteristics for capture detection, albeit only significantly at the extended pulse duration (79% vs 97%, p < 0.05) and at simultaneous and positive interventricular delays (81% vs 97%, p < 0.05).
Conclusions:

Though LV capture detection was feasible using both investigated methods, the RCC method (LVTip→Can) sensitivity to the evaluated pacing parameters suggests the IPS method (LVRing→Can) provides a more robust performance.
Predicting Imminent Episodes of Ventricular Tachyarrhythmia Using Heart Rate
Authors: THONG TRAN , RAITT MERRITT H. 
Published: June 2007

Background:A reliable predictor of an imminent episode of ventricular tachyarrhythmia that could be incorporated in an implantable defibrillator capable of preventive therapy would have important clinical utility.Method:A test set of 208 R–R records saved by defibrillators spanning a mean of 1.6 hours before sustained tachyarrhythmia were used to derive criteria that would improve the specificity of the previously identified monotonic heart rate acceleration predictor. Additional criteria were used, namely two such patterns need to occur within a period of 1.8 hour and the heart rate during these accelerations exceeds 86 bpm (700 ms). The specificity was tested using R–R records matched in duration from 26 control patients with defibrillators during normal periods.Results:The basic acceleration pattern was found during sinus rhythm in the 1.8‐hour period prior to 83% of episodes of ventricular tachyarrhythmia. It was also found in 43% of the matched set of nonarrhythmic records, corresponding to a specificity of 57%. With the two extra requirement of multiplicity within 1.8 hour and peak heart rate, the sensitivity of the proposed predictor is reduced to 53%, but the specificity is increased to 91%, which corresponds to an average false positive rate of 0.8 event/day across the patient population.Conclusion:A ventricular tachyarrhythmia predictor based on a pattern of heart rate acceleration has been proposed that can yield sensitivity from 53% to 69%, with specificity up to 91%. Instances of this predictor increase significantly prior to an episode of tachyarrhythmia.
What is the prevalence of various types of prosthetic dental restorations in Europe?
Authors: Zitzmann Nicola Ursula , Hagmann Edgar , Weiger Roland 
Published: June 2007

AbstractObjectives: The aim of this review was to analyse the prevalence of prosthetic dental restorations in the adult population in Europe and to investigate factors influencing the frequencies of fixed restorations and removable dental prostheses (RDP).Material and methods: A search for literature up to 31 October 2006 on dental restorations was performed in Medline via PubMed and in an additional hand search using several keywords related to epidemiology and dental restorations. Out of approximately 6000 titles listed, 136 articles were identified, which were related to 13 different European countries. 43 articles fulfilled the inclusion criteria and were included in this review.Results: Approximately half of the adult population in most European countries have had some type of prosthetic dental restoration. The frequency of RDPs among adults varied between 13 and 29%, with 3–13% edentulous subjects wearing complete dentures in both jaws. The frequency of fixed restorations including crowns and fixed dental prostheses (FDPs, bridges) was the highest in Sweden with 45% and Switzerland (34%). In the recent decades, there has been a slight decrease in RDP use reflecting a decline in edentulism, while more subjects had maintained a residual dentition and were wearing removable partial dentures or fixed restorations. The latter are less prevalent in countries with lower prosperity. If only a few teeth are absent, these are generally replaced with FDPs or have no replacement. If more teeth are missing, the likelihood of a removable restoration increases with the number of teeth to be replaced. A higher frequency of removable restorations is present in older age groups, in subjects living in rural areas, in those from a lower socio‐economic status and in subjects with less education and lower incomes.Conclusions: All types of fixed and removable restorations are highly prevalent, especially among older age groups, in most European countries. There is a trend towards higher frequencies of fixed restorations, more removable partial dentures and a reduction in complete dentures.
Ante's (1926) law revisited: a systematic review on survival rates and complications of fixed dental prostheses (FDPs) on severely reduced periodontal tissue support

Published: June 2007

AbstractBackground: In subjects suffering from generalized severe periodontitis, only a few teeth may be treated and used as abutments for fixed dental prostheses (FDPs).Objective: To systematically review the impact of severely reduced, but healthy periodontal tissue support on the survival rate and complications of FDPs after a mean follow‐up time of at least 5 years.Search strategy: Publications considered for inclusion were searched in MEDLINE (PubMed) and relevant journals were hand searched. The search was performed in duplicate and was limited to human studies published in the dental literature from 1966 up to and including September 2006. Only publications in English, in peer‐reviewed journals, were considered. Abstracts were excluded.Selection criteria: Prospective and retrospective cohort studies were included. The primary outcome measure included survival rates of FDPs and abutment teeth, whereas biological and technical complications of FDPs and abutment teeth represented secondary outcome measures.Data analysis: Summary estimates of survival rates and of biological and technical complications were calculated after 5 and 10 years.Results: The search provided 860 titles of which six publications were included. A total of 579 FDPs were incorporated and followed up to 25 years. Meta‐analysis yielded an estimated FDP survival rate of 96.4% [95% confidence interval (95% CI): 94.6–97.6%] after five and of 92.9% (95% CI: 89.5–95.3%) after 10 years, respectively. After 10 years, the estimated rate of abutment teeth without endodontic complications amounted to 93% (95% CI: 62.6–98.9%). The 10‐year estimated rate of caries‐free abutment teeth was 98.1% (95% CI: 88.2–99.7%). FDPs without loss of retention were estimated to occur in 95.4% (95% CI: 92.6–97.2%) of cases after 10 years.Conclusions: These results showed that (i) masticatory function could be established and maintained in subjects receiving FDPs on abutment teeth with severely reduced but healthy periodontal tissue support and (ii) FDPs survival rates compared favourably with those of FDPs incorporated in subjects without severely periodontally compromised dentitions.
Comparison of survival and complication rates of tooth‐supported fixed dental prostheses (FDPs) and implant‐supported FDPs and single crowns (SCs)

Published: June 2007

AbstractObjectives: The objective of this systematic review was to assess and compare the 5‐ and 10‐year survival of different types of tooth‐supported and implant‐supported fixed dental prosthesis (FDPs) and single crowns (SCs) and to describe the incidence of biological and technical complications.Methods: Three electronic searches complemented by manual searching were conducted to identify prospective and retrospective cohort studies on FDPs and SCs with a mean follow‐up time of at least 5 years. Patients had to have been examined clinically at the follow‐up visit. Failure and complication rates were analyzed using random‐effects Poisson's regression models to obtain summary estimates of 5‐ and 10‐year survival proportions.Results: Meta‐analysis of the included studies indicated an estimated 5‐year survival of conventional tooth‐supported FDPs of 93.8%, cantilever FDPs of 91.4%, solely implant‐supported FDPs of 95.2%, combined tooth‐implant‐supported FDPs of 95.5% and implant‐supported SCs of 94.5%. Moreover, after 10 years of function the estimated survival decreased to 89.2% for conventional FDPs, to 80.3% for cantilever FDPs, to 86.7% for implant‐supported FDPs, to 77.8% for combined tooth‐implant‐supported FDPs and to 89.4% for implant‐supported SCs. Despite high survival rates, 38.7% the patients with implant‐supported FDPs had some complications after the 5‐year observation period. This is compared with 15.7% for conventional FDPs and 20.6% for cantilever FDPs, respectively. For conventional tooth‐supported FDPs, the most frequent complications were biological complications like caries and loss of pulp vitality. Compared with tooth‐supported FDPs, the incidence of technical complications was significantly higher for the implant‐supported reconstructions.The most frequent technical complications were fractures of the veneer material (ceramic fractures or chipping), abutment or screw loosening and loss of retention.Conclusion: On the basis of the results of the present systematic review, planning of prosthetic rehabilitations should preferentially include conventional end abutment tooth‐supported FDPs, solely implant‐supported FDPs or implant‐supported SCs. Only for reasons of anatomical structures or patient‐centered preferences and as a second option should cantilever tooth‐supported FDPs or FDPs supported by combination of implants and teeth be chosen.
To what extent does the longevity of fixed dental prostheses depend on the function of the cement? Working Group 4 materials: cementation
Authors: Edelhoff Daniel , Özcan Mutlu 
Published: June 2007

AbstractAims/Background: The objective of this review was to define the impact of cementation mode on the longevity of different types of single tooth restorations and fixed dental prostheses (FDP).Methods: Literature search by PubMed as the major database was used utilizing the terms namely, adhesive techniques, all‐ceramic crowns, cast‐metal, cement, cementation, ceramic inlays, gold inlays, metal‐ceramic, non‐bonded fixed‐partial‐dentures, porcelain veneers, resin‐bonded fixed‐partial‐dentures, porcelain‐fused‐to‐metal, and implant‐supported ‐ restorations together with manual search of non‐indexed literature. Cementation of root canal posts and cores were excluded. Due to lack of randomized prospective clinical studies in some fields of cementation, recommendations had to be based on lower evidence level (Centre of Evidence Based Medicine, Oxford) for special applications of current cements.Results: One‐hundred‐and‐twenty‐five articles were selected for the review. The primary function of the cementation is to establish reliable retention, a durable seal of the space between the tooth and the restoration, and to provide adequate optical properties. The various types of cements used in dentistry could be mainly divided into two groups: Water‐based cements and polymerizing cements. Water‐based cements exhibited satisfying long‐term clinical performance associated with cast metal (inlays, onlays, partial crowns) as well as single unit metal‐ceramic FDPs and multiple unit FDPs with macroretentive preparation designs and adequate marginal fit. Early short‐term clinical results with high‐strength all‐ceramic restorations luted with water‐based cements are also promising. Current polymerizing cements cover almost all fields of water‐based cements and in addition to that they are mainly indicated for non‐retentive restorations. They are able to seal the tooth completely creating hybrid layer formation. Furthermore, adhesive capabilities of polymerizing cements allowed for bonded restorations, promoting at the same time the preservation of dental tissues.
In patients with temporomandibular disorders, do particular interventions influence oral health‐related quality of life? A qualitative systematic review of the literature
Authors: Türp Jens C. , Motschall Edith , Schindler Hans J. , Heydecke Guido 
Published: June 2007

AbstractObjectives: The use of patient‐based outcomes to measure therapeutic effectiveness is increasing, because a growing number of clinical scientists are attempting to evaluate the impact of therapy on the recipient. There are indications that patients suffering from temporomandibular disorders (TMDs) may also show a reduced oral health‐related quality of life (OHQoL). It was the purpose of this paper to answer the question as to whether therapeutic interventions in TMD patients have a positive effect on their OHQoL.Material and methods: A systematic electronic search (Ovid Medline® 1966–2006; Science Citation Index 1945–2006) of the literature was carried out to identify pertinent articles of randomized and non‐randomized clinical trials. Reports on retrospective and prospective studies that specifically focused on OHQoL changes in TMD patients as a consequence of therapeutic interventions were included. The reference lists of the identified articles were screened to find additional pertinent publications.Results: The investigation yielded seven relevant contributions from Medline®. A quantitative analysis of the seven identified articles was not possible. There was considerable heterogeneity among the investigations with regard to study design, patient characteristics, and provided therapy. Three of the identified articles reported about prospective controlled studies, of which one was an RCT. Four additional investigations were retrospective. According to the results of the only RCT, a 6‐week course of the non‐selective cyclooxygenase (COX) inhibitor naproxen may lead to slightly better OHQoL in patients with temporomandibular joint (TMJ) arthralgia than the selective COX‐2 inhibitor celecoxib. The two other articles reporting of a controlled study showed that selective serotonine uptake inhibitors accompanied by psychological therapy improved OHQoL in individuals with TMJ arthralgia. In contrast, TMJ surgery did not improve OHQoL.Conclusion: It appears that all therapeutic interventions reported in the identified publications led to at least some improvement of OHQoL. The only exception were patients with multiple TMJ surgeries.
The bases for using a particular occlusal design in tooth and implant‐borne reconstructions and complete dentures

Published: June 2007

AbstractObjectives: A systematic review identified randomised and other trials (1966–2006) of studies of occlusal design of crowns, complete (CRP) and partial (PRP) removable prostheses and implant‐borne reconstructions, and whether occlusal design influenced diet, quality of life, bruxism and attrition.Methods: The search primarily included Cochrane Database of Systematic Reviews and Central Register of Controlled Trials, Database of Abstracts of Reviews of Effectiveness, Ovid Medline and PreMedline.Results: The search yielded 1315 studies: 20 on CRP – 1 RCT, one systematic review, four clinical trials, 10 case series; 22 on PRP – one cohort study, two experimental studies, 15 case reports or case series, three clinical trials; 23 on implant superstructures, and 24 reports on implant failure, 37 on oral health related quality of life, eight on attrition; and four studies on masticatory function.Conclusions: CRP – Studies of occlusal form and tooth arrangements, included balanced, lingualised and monoplane arrangements – lingualised posterior occlusion was preferred.Early studies on CRP design were observational as case reports, however data suggested that optimum function is achieved by modification of the maxillary occlusion, irrespective of the opposing mandibular occlusion.PRP – Edentulous ridge resorption is patient‐specific, has a multifactorial aetiology and there is no objective data to confirm that mechanical factors cause bone loss; oral hygiene management is crucial for long‐term health.Studies on distal extension PDs confirmed a link between bite force and masticatory function; preservation of two functioning posterior tooth units ipsilateral to the distal extension optimises function. Data indicate that patient‐specific factors, rather than PD design‐specific features, influence long‐term PD outcomes.Implant superstructures – There is little scientific evidence specifying occlusal and superstructure design for fixed prostheses for teeth or implants. Occlusal scheme design and occlusal form have evolved through clinical experience, but there is no evidence to indicate that a particular design is superior.Complex neurophysiological mechanisms allow the jaw muscle system to accommodate to oral and dental changes.
Supportive therapy and the longevity of dental implants: a systematic review of the literature
Authors: Hultin Margareta , Komiyama Ai , Klinge Björn 
Published: June 2007

AbstractObjective: To review systematically whether supportive implant treatment during a follow‐up of at least 10 years after functional loading is effective in prevention of biological complications and fixture loss.Methods: A MEDLINE search was conducted for the period of 1965 to April 2006 of longitudinal clinical studies with follow‐up periods after implant function of at least 10 years. Sixty‐two studies were initially screened for inclusion and read in full text. Nine studies remained for the final assessment and 53 articles were thus excluded for the following reasons: (1) no information on implant maintenance was presented, (2) the number of patients/implants assessed at 10‐year follow‐up/final evaluation was not presented (3) fixture loss and marginal bone loss during function were not assessed at 10‐year evaluation and (4) residual inflammation and/or probing pocket depth (PPD) not assessed at 10‐year examination.Results: Fifty‐six percent of 62 initially screened studies did not assess clinical inflammation and PPD around implants at long‐term evaluation of implants. This was the most common reason for exclusion of studies. In 28% of excluded studies, there was no information on implant maintenance during follow‐up. A total of 749 fixtures were included and followed for more than 10 years of functional load. Five of the included studies gave no detailed information of the assessments or the treatment at follow‐up visits during the 10 years. Only in two of the included cohorts were patients enrolled in an individualized supportive program on a 3–6‐month recall interval.Conclusion: There are, to date, few available studies evaluating the long‐term effect of supportive programs for implant patients. Based on the nine studies included, no evidence is available to suggest the frequency of recall intervals or to propose specific hygiene treatments. There is an urgent need for such studies to be initiated.
