Adipositas als chronische Erkrankung ist zu einem der Hauptgesundheitsprobleme der Weltbevölkerung im 21. Jahrhundert geworden. Starkes Übergewicht und Adipositas gelten als Risikofaktoren für eine Reihe systemischer Erkrankungen. Meist bringt man die vermehrte Ansammlung von Fettdepots mit kardiovaskulären Erkrankungen oder Diabetes in Verbindung. Doch auch in der oralen Gesundheit macht sich starkes Übergewicht bemerkbar. In den letzten Jahren wurde in der Literatur zunehmend der Zusammenhang zwischen Parodontitis und Übergewicht bzw. Adipositas thematisiert und wissenschaftlich belegt. Die vorliegende Arbeit beschäftigt sich mit der Frage, inwieweit sich die Lokalisation der Fettdepots an unterschiedlichen Körperregionen auf die Entstehung und den Verlauf einer Parodontitis auswirkt und ob es einen bidirektionalen Zusammenhang zwischen Parodontitis und den spezifischen Fettverteilungsmustern gibt. Die statistischen Analysen wurden basierend auf Datensätzen der Follow-Up-Untersuchung SHIP-2 der Study of Health in Pomerania angefertigt.
Background: COVID-19 lead to the adoption of containment measures including temporary closure of dental clinics. Despite the risk of infection transmission, dental emergencies have not ceased during this pandemic and had to be managed also in the lockdown period.
Aim: To analyze the profiles and offered management options of pediatric patients presenting with dental emergencies during a COVID-19 lockdown.
Design: Retrospective analysis of patient records of children seeking emergency dental treatment during a 7-week lockdown period in 2020 in a university pedodontics clinic in Germany, compared to a similar cohort from 2019. Data on patient level, tooth level, and session level were collected. An analysis of the digital records after 6 months follow-up was performed for the patients who received Non-Aerosol Generating Procedures (NAGP) as management for dental emergency in the lockdown period in 2020.
Results: The 2020 cohort consisted of 83 patients, while the 2019 cohort included 46 patients showing 45% higher necessity for emergency treatment in 2020. Most common chief complaint was oral mucosal conditions in 2020 (26.4%), and irreversible pulpitis in 2019 (25.5%). Dental caries (without spontaneous pain) was the second most chief complaint in both cohorts (20.7% and 23.4% respectively). Most interventions in 2020 were Minimally Invasive Treatments such as the hall technique and silver diammine fluoride (20.3%), which were in 2019 not considered, followed by pharmacological treatment (16.9%), which were in 2019 also highly used (35.9%). The 6 months follow up for the NAGP revealed benefit in management of the acute dental problem, by either direct treatment or by postponing the treatment need to a later time period.
Conclusion: The COVID-19 pandemic led to increase in emergency pediatric dental visits and shifted treatment options towards less invasive procedures.
In challenging situations, where aerosols increase the risk of infection transmission, NAPD are a viable option in the management of dental emergencies, especially in pediatric dentistry.
Abstract
Objective
To evaluate the efficacy of tooth splinting (TS) and occlusal adjustment (OA) compared to no TS or OA in patients with periodontitis exhibiting masticatory dysfunction.
Material
The primary outcome criterion was tooth loss (TL), and the secondary outcome parameters were change in probing pocket depth (PPD), change in clinical attachment level (CAL), tooth mobility (TM), and patient‐reported outcome measures (PROMs). Literature search was performed on three electronic databases (from 01/1965 to 04/2021) and focused on clinical studies with at least 12 months follow‐up.
Results
From a total of 1515 publications, 51 articles were identified for full‐text reading, of which 2 retrospective case series on TS with low risk of bias and 1 randomized and 2 prospective studies on OA with unclear risk of bias were included. For TS, synthesis of data showed that in 72 patients, 26 out of 311 teeth (weighted mean incidence of TL 8.4%) and 156 out of 1541 teeth with no TS (weighted mean incidence of TL 10.1%) were lost over 2 years following non‐surgical periodontal therapy. The randomized controlled clinical trial (RCT) indicated CAL gain for teeth with OA compared to no OA. For the effect of OA on TL, PPD, and TM, heterogeneous data were retrieved from the included studies.
Conclusions
Within the limitations of this review and based on a low level of evidence, it is concluded that TS does not improve survival of mobile teeth in patients with advanced periodontitis. OA on teeth with mobility and/or premature contacts may lead to improved CAL, while the effect of OA on the remaining periodontal parameters remains unclear.
Periodontitis is a multifactorial disease. The aim of this explorative study was to investigate the role of Interleukin-(IL)-1, IL-4, GATA-3 and Cyclooxygenase-(COX)-2 polymorphisms after non-surgical periodontal therapy with adjunctive systemic antibiotics (amoxicillin/metronidazole) and subsequent maintenance in a Caucasian population. Analyses were performed using blood samples from periodontitis patients of a multi-center trial (ClinicalTrials.gov NCT00707369=ABPARO-study). Polymorphisms were analyzed using quantitative real-time PCR. Clinical attachment levels (CAL), percentage of sites showing further attachment loss (PSAL) ≥1.3 mm, bleeding on probing (BOP) and plaque score were assessed. Exploratory statistical analysis was performed. A total of 209 samples were genotyped. Patients carrying heterozygous genotypes and single-nucleotide-polymorphisms (SNP) on the GATA-3-IVS4 +1468 gene locus showed less CAL loss than patients carrying wild type. Heterozygous genotypes and SNPs on the IL-1A-889, IL-1B +3954, IL-4-34, IL-4-590, GATA-3-IVS4 +1468 and COX-2-1195 gene loci did not influence CAL. In multivariate analysis, CAL was lower in patients carrying GATA-3 heterozygous genotypes and SNPs than those carrying wild-types. For the first time, effects of different genotypes were analyzed in periodontitis progression after periodontal therapy and during supportive treatment using systemic antibiotics demonstrating a slight association of GATA-3 gene locus with CAL. This result suggests that GATA-3 genotypes are a contributory but non-essential risk factor for periodontal disease progression.
To assess whether the treatment of children with oral midazolam and pediatric hypnosis techniques can improve the compliance in consecutive sessions, a retrospective longitudinal practice-based observational study was designed and carried out. A total of 311 children between 3 and 12 years of age were treated under hypnosis and sedation with midazolam (0.40 mg/kg body weight). Treatments were performed in one to a maximum of three sessions. A total of 183 children received one, 103 received two and 25 children received three treatment sessions. The behavior of the children during the sessions was examined by means of the Venham score. The self-evaluation of the children was based on the Wong–Baker Scale. Child behavior using midazolam and hypnosis techniques showed little difference and good compliance between the sessions. Venham scores did not increase significantly regarding total treatment from the first (0.99 ± 1.41) to the second (1.17 ± 1.39) and to the third session (1.27 ± 1.20) (p > 0.05). However, considering the highest Venham scores that occurred in each case, the behavior of the children worsened significantly (p < 0.01) during the three treatment sessions, from 1.37 ± 1.31 (first) to 1.87 ± 1.74 (second) to 2.32 ± 1.33 (third). In 6.11% of the children, treatment was discontinued in the first session (n = 19), 0.96% in the second (n = 3) and 0% in the third. Treatment with low-dose midazolam, combined with hypnosis techniques, showed to be an effective option for dental treatment in children. Within the limitations of the current study, and with consideration of highest possible compliance, no more than two treatment sessions for pediatric dental treatment should be performed.
Because of some disadvantages of chemical disinfection in dental practice (especially denture cleaning), we investigated the effects of physical methods on Candida albicans biofilms. For this purpose, the antifungal efficacy of three different low-temperature plasma devices (an atmospheric pressure plasma jet and two different dielectric barrier discharges (DBDs)) on Candida albicans biofilms grown on titanium discs in vitro was investigated. As positive treatment controls, we used 0.1% chlorhexidine digluconate (CHX) and 0.6% sodium hypochlorite (NaOCl). The corresponding gas streams without plasma ignition served as negative treatment controls. The efficacy of the plasma treatment was determined evaluating the number of colony-forming units (CFU) recovered from titanium discs. The plasma treatment reduced the CFU significantly compared to chemical disinfectants. While 10 min CHX or NaOCl exposure led to a CFU log10 reduction factor of 1.5, the log10 reduction factor of DBD plasma was up to 5. In conclusion, the use of low-temperature plasma is a promising physical alternative to chemical antiseptics for dental practice.
Die Entscheidung für das optimale Füllungsmaterial in der zahnärztlichen Behandlung stellt für Patienten und auch deren behandelnde Zahnärzte heutzutage eine Herausforderung dar. Bei der Vielzahl an zahnärztlichen Materialien, die heute angeboten werden, stellt sich die Frage, welches Material sich am besten für die Behandlung von Zahnhartsubstanzdefekten eignet, insbesondere im Bereich der Molaren.
Um einen Anhaltspunkt zu erhalten, welches Material am besten geeignet ist, wurden in der vorliegenden Studie Zahnärzte in Deutschland befragt, wie sie ihre eigenen Molaren restauriert haben und wie haltbar diese Restaurationen sind.
Mit Hilfe einer Onlineumfrage wurden Daten von 299 Zahnärzten über die restaurative Behandlung ihrer Molaren erhoben. Nach der Korrektur bestand der Analysesatz aus 1719 Molaren von 288 Zahnärzten.
Im Ergebnis zeigt sich innerhalb der Grenzen dieser Studie, dass bei deutschen Zahnärzten Restaurationen aus metallischen Werkstoffen wie Gold, Amalgam oder Nichtedelmetallen in ihren Molaren überwiegen, wobei Gold den größten Anteil ausmacht. Unterschiede wurden in Bezug auf das Geschlecht, das Alter und die Region, in welcher der Zahnarzt tätig ist, festgestellt. Es zeigte sich außerdem, dass Zahnärztinnen zahnfarbene Materialien wie beispielsweise Restaurationen aus Keramik bevorzugen. Restaurationen aus Gold, Amalgam und Nichtedelmetall zeigten mit mehr als 20 Jahren die höchste Haltbarkeit.
Es lässt sich jedoch eine Trendwende erkennen. So wählen insbesondere jüngere Zahnärzte neuere Materialien wie Komposit und Keramik für die restaurative Versorgung ihrer Molaren. Diese Materialien wurden in den vergangenen Jahren ständig weiterentwickelt und zeigen heutzutage deutlich verbesserte Eigenschaften was die Haltbarkeit und die Ästhetik betrifft, als noch vor einigen Jahren.
In Bezug auf die Entscheidungsfindung hinsichtlich eines gewählten oder auch empfohlenen Materials zeigt sich, dass die Entscheidung von verschiedenen Faktoren beeinflusst wird. Wichtig sind beispielsweise die Eigenschaften der verschiedenen Materialien, ebenso wie die Lage, Art und Größe des Defektes. Auch die Mundhygiene beziehungsweise das Kariesrisiko haben einen Einfluss.
Da in der Zahnmedizin die Prävention immer weiter in den Fokus rückt ist anzunehmen, dass auch unter Zahnärzten die Anzahl der nötigen größeren Restaurationen im Seitenzahnbereich abnehmen und sich dementsprechend auch die Art der gewählten Materialien weiter verändern wird.
The Study of Health in Pomerania (SHIP), a population-based study from a rural state in northeastern Germany with a relatively poor life expectancy, supplemented its comprehensive examination program in 2008 with whole-body MR imaging at 1.5 T (SHIP-MR). We reviewed more than 100 publications that used the SHIP-MR data and analyzed which sequences already produced fruitful scientific outputs and which manuscripts have been referenced frequently. Upon reviewing the publications about imaging sequences, those that used T1-weighted structured imaging of the brain and a gradient-echo sequence for R2* mapping obtained the highest scientific output; regarding specific body parts examined, most scientific publications focused on MR sequences involving the brain and the (upper) abdomen. We conclude that population-based MR imaging in cohort studies should define more precise goals when allocating imaging time. In addition, quality control measures might include recording the number and impact of published work, preferably on a bi-annual basis and starting 2 years after initiation of the study. Structured teaching courses may enhance the desired output in areas that appear underrepresented.
Aim: To provide recommendations for dental clinicians for the management of dental caries in older adults with special emphasis on root caries lesions. Methods: A consensus workshop followed by a Delphi consensus process were conducted with an expert panel nominated by ORCA, EFCD, and DGZ boards. Based on a systematic review of the literature, as well as non-systematic literature search, recommendations for clinicians were developed and consented in a two-stage Delphi process. Results: Demographic and epidemiologic changes will significantly increase the need of management of older adults and root caries in the future. Ageing is associated with a decline of intrinsic capacities and an increased risk of general diseases. As oral and systemic health are linked, bidirectional consequences of diseases and interventions need to be considered. Caries prevention and treatment in older adults must respond to the patient’s individual abilities for self-care and cooperation and often involves the support of caregivers. Systemic interventions may involve dietary counselling, oral hygiene instruction, the use of fluoridated toothpastes, and the stimulation of salivary flow. Local interventions to manage root lesions may comprise local biofilm control, application of highly fluoridated toothpastes or varnishes as well as antimicrobial agents. Restorative treatment is often compromised by the accessibility of such root caries lesions as well as the ability of the senior patient to cooperate. If optimum restorative treatment is impossible or inappropriate, long-term stabilization, e.g., by using glass-ionomer cements, and palliative treatments that aim to maintain oral function as long and as well as possible may be the treatment of choice for the individual.
The aim of the present study was to construct a biological age score reflecting one’s physiologic capability and aging condition with respect to tooth loss over 10 y. From the follow-up to the population-based Study of Health in Pomerania (i.e., SHIP-2), 2,049 participants were studied for their baseline biomarker measures 10 y before (i.e., in SHIP-0). Metabolic and periodontal data were regressed onto chronological age to construct a score designated as “biological age.” For either sex separately, the impact of this individualized score was used to predict tooth loss in the follow-up cohort in comparison with each participant’s chronological age. Outcome data after 10 y with respect to tooth loss, periodontitis, obesity, and inflammation were shown to be better for biologically younger subjects than as expected by their chronological age, whereas for the older subjects, data were worse. Especially for tooth loss, a striking increase was observed in subjects whose biological age at baseline appeared to be higher than their chronological age. Biological age produced significantly better tooth loss predictions than chronological age (P < 0.001). Areas under receiver operating characteristic curves for tooth loss of ≥3 teeth in men during follow-up were 0.811 and 0.745 for biological and chronological age, respectively. For women, these figures were 0.788 and 0.724. For total tooth loss, areas under the curve were 0.890 and 0.749 in men and 0.872 and 0.752 in women. Biological age combines various measures into a single score and allows identifying individuals at increased risk of tooth loss.
