Up to now, indices like the mean dmft/DMFT and the SiC (Significant Caries Index) have been used to depict caries experience in populations with high prevalence. With the caries decline, particularly for populations with low caries levels, these indices reach their statistical limits. This paper aims to introduce a specific term, the Specific affected Caries Index (SaC) for the risk groups in populations with low caries prevalence and to illustrate its use based on the consecutive German National Oral Health Survey (GNOHS) in children. In groups with a caries prevalence less than one-third of the population, many caries-free children (DMFT = 0) are included in the SiC (risk group), which calls for a new way of illustration. Mean caries experience (DMFT), caries prevalence, the SiC and SaC were portrayed for 12-year-olds in the GNOHS from 1994/95 to 2016. The SaC describes the mean caries experience (DMFT) in the group presenting caries experience (DMFT > 0). In 12-year-old 6th graders in Germany, the mean caries experience decreased from 2.4 (1994/95) to 0.4 DMFT (2016), with a recent prevalence of 21.2% (DMFT > 0, 2016). In 2016, the mean number of affected teeth in children with DMFT > 0 (SaC) was 2.1, while the SiC including 12% DMFT-free children in the risk group was 1.3. The SiC fails to reflect the caries severity in children in a population with low caries prevalence. Therefore, the newly introduced term Specific affected Caries Index (SaC) may be used to describe accurately caries experience in caries risk children in populations presenting low caries prevalence.
National oral health survey on refugees in Germany 2016/2017: caries and subsequent complications
(2020)
Objectives To assess oral health, caries prevalence, and subsequent complications among recently arrived refugees in Germany and to ompare these findings with the German resident population. Methods This multicenter cross-sectional study recruited 544 refugees aged 3–75+ years; they were examined at ten registration institutions in four federal states in Germany by two calibrated dentists. The refugees were screened for caries (dmft/DMFT) and its complications pufa/PUFA); this data was compared to the resident population via the presentative national oral health surveys). Results The deciduous dentition of the 3-year-old refugees had a mean dmft value of 2.62 ± 3.6 compared with 0.48 dmft in the German resident population, and caries increased to 5.22 ± 3.4 for 6–7-year-olds (Germany: 1.73 dmft). Few refugee children had naturally healthy teeth (7% in 6–7-year-olds, Germany: 56%). In the permanent dentition, the gap in caries prevalence between refugees and the German population decreased with age (35–44-year-olds: 10.55 ± 7.1 DMFT; Germany: 11.2), but refugees exhibited more caries defects (35–44-year-olds DT = 3.13 ± 3.0; Germany: 0.5). German residents had more restorations (35–44-year-olds FT = 4.21 ± 4.6). Regarding complications, the 6–7-year-olds exhibited the highest pufa index (0.86 ± 1.4) which decreased in adolescence (13–17-year-olds, 0.18 ± 0.6) and increased in adults (45–64-year-olds, 0.45 ± 0.8). Conclusion The refugees had high caries experience, often untreated caries teeth and more complications compared with the German resident population, especially in children. Closing this gap by extending preventive systems to the refugees would decrease future treatment needs. Clinical relevance European countries should be prepared for the higher dental treatment needs in recent refugees, especially in
children.
For an Organisation for Caries Research/European Federation of Conservative Dentistry consensus, this systematic review is aimed to assess the question of how to manage the caries process in the case of early childhood caries (ECC). Medline via PubMed was searched systematically regarding management of ECC. First priority was existing systematic reviews or randomized clinical trials otherwise cohort studies dealing with management of ECC, primarily with carious anterior teeth. After data extraction, the potential risk of bias was estimated depending on the study types, and the level of evidence was evaluated. Regarding management of ECC, results are presented for silver diamine fluoride (SDF, n = 5), nonoperative caries management (NOCM, n = 10), and restorative approaches (RA, n = 8) separately, as different kinds of studies with different levels of evidence were found for the different aspects in the management of ECC. The 5 systematic reviews on SDF showed a high potential for arrest of ECC on a high level of evidence. In NOCM, a low level of evidence for a moderate effect of fluoride varnish in arresting or remineralizing, especially non-cavitated lesions, was assessed. For RA in carious anterior upper primary teeth, a low level of evidence was found for higher failure rates of glass ionomer cement and composite fillings than composite strip crowns even if placed under general anaesthesia and especially compared to other crowns (stainless steel and zirconia). In conclusions, ECC may be managed successfully with nonoperative (SDF, regular fluoride application) and moderately well with operative approaches, but the decision is affected by many other variables such as pulpal involvement, the child’s cooperation, or a general anaesthesia setting.
In fixed orthodontic treatments debonding of brackets during treatment is an unpleasant occurrence for the clinician and the patients and resultes in an increase in treatment costs and duration. For Damon Q brackets recycling would considered as an economic saving option which could be done with using of in office methods such as the sandblasting.
A sample of sixty sound bovine first upper central incisers, were collected, cleaned, and mounted in acrylic blocks for shear bond strength testing.
The total sample was equally divided into two main groups. Each group had 30 teeth and 30 brackets.
The first group had 30 teeth bonded with metal Damon Q brackets, the second group had 30 teeth bonded with metal Mini-Mono® brackets.The study included bonding and rebonding experiments. Therefore the same brackets with their same teeth were used in bonding and in the rebonding experiments. The bonding and the rebonding procedures were done with using 3M Unitek etching, Grengloo adhasive, and Ortho solo bonding. In addition the rebonding procedure was done after cleaning the teeth and recycling their brackets with sandblasting. All specimens were recycled 5000 times for the bonding and rebonding experiments.
The first and second debonding forces were done in Newton using a Zwick Roell machine.
After that SBS and SRS were computed in MPa. Furthermore all the teeth, after each debonding, were examined under a digital scanning microscope VHX-5000, 50X magnifying, to performe the ARA and ARI.
The collected data was statistically analyzed for descriptive statistics as well as significance of differences among the different bracket types, and their ARI scores, in the bonding and rebonding experiments.
The results showed that SRS was significantly higher than SBS of both types of the brackets, and Damon Q brackets had higher SBS, and SRS than Mini-Mono® brackets, and there was no correlation between SBS, SRS and their ARI, ARA.
Abstract
Background
Knowledge of molar incisor hypomineralization (MIH) has relevance for paediatric dentists.
Aim
To assess final‐year German dental students’ knowledge, attitudes, and beliefs regarding MIH.
Materials and methods
A previously validated questionnaire was posted to the 31 German dental schools. Demographic covariates as well as knowledge regarding
diagnosis and prevalence, and attitudes and beliefs around aetiology and management were collected.
Results
Twenty‐two (71%) dental schools responded and a total of 877 students participated. Most (97%) were familiar with MIH and 88% were aware of the diagnostic criteria for MIH; however, only 42% knew how to implement them. One‐third were able to identify MIH and 16% reported diagnostic confidence when doing so; 90% assumed the MIH prevalence to be <10%. Two‐thirds of the respondents implicated genetic components as the main aetiological factor of MIH. Resin composite (60%) and preformed metal crowns (46%) were the dental materials most often suggested for restorative management. Almost all (98%) respondents were interested in receiving more clinical training.
Conclusion
German students were familiar with MIH; however, they reported low levels of knowledge and confidence regarding its prevalence and diagnosis. Standardized nationwide, up‐to‐date curricula should be implemented to educate future dentists in Germany.
For an ORCA/EFCD consensus, this review systematically assessed available evidence regarding interventions performed and materials used to manage dentin carious lesions in primary teeth. A search for systematic reviews (SRs) and randomized clinical trials (RCTs) with a follow-up of at least 12 months after intervention was performed in PubMed, LILACS, BBO, and the Cochrane Library. The risk of bias tool from the Cochrane Collaboration and the PRISMA Statement were used for assessment of the included studies. From 101 screened articles, 2 SRs and 5 RCTs, which assessed the effectiveness of interventions in terms of pulp vitality and success of restoration, and 10 SRs and 1 RCT assessing the success of restorative materials were included. For treatments involving no carious tissue removal, the Hall technique showed lower treatment failure for approximal carious lesions compared to complete caries removal (CCR) and filling. For the treatment of deep carious lesions, techniques involving selective caries removal (SCR) showed a reduction in the incidence of pulp exposure. However, the benefit of SCR over CCR in terms of pulp symptoms or restoration success/failure was not confirmed. Regarding restorative materials, preformed metal crowns (PMCs) used to restore multisurface lesions showed the highest success rates compared to other restorative materials (amalgam, composite resin, glass ionomer cement, and compomer), and in the long term (12–48 months) these were also less likely to fail. There is limited evidence supporting the use of PMCs to restore carious lesions with single cavities. Among nonrestorative options, silver diammine fluoride was significantly more effective in arresting caries than other treatments for treating active carious lesions of different depths. Considerable heterogeneity and bias risk were observed in the included studies. Although heterogeneity observed among the studies was substantial, the trends were similar. In conclusion, less invasive caries approaches involving selective or no caries removal seem advantageous in comparison to CCR for patients presenting with vital, symptomless, carious dentin lesions in primary teeth. There is evidence in favor of PMCs for restoring multisurface carious lesions in primary molars.
Primary tooth trauma occurs commonly during the development of motor coordination. Its consequences do not only affect the traumatized primary tooth but may affect the underlying permanent successor as well. Its management may involve very high costs on patients and insurance companies and complicated injuries can have negative effects on the quality of life of preschool children. Investigating the causes and patterns of trauma in primary teeth are highly needed to aim for preventive measures. This retrospective study compared the patterns of dental trauma injuries at the trauma center at Greifswald University/Germany for a recent pediatric cohort (2014-16, 103 children) with a historic one before the German unification and the health care system reformation (1974-1989, n=120). The data contained details on etiology, injury types and treatment delivered for 450 injured teeth (247 historic, 203 recent). In both cohorts, the occurrence was more common in males than females (63%/55%, resp.) with an age peak from 2 to 6 years. Maxillary incisors were most affected (89.6%/88.6%, resp.) and periodontal ligament injuries dominated (77.8%/90.3%, resp.).
Almost half of the injuries occurred at home (46.6%), mostly due to falling (48.5%) or during playing (37.8%) in the recent pediatric cohort which provided better forensic data due to insurance issues and potential concern about child abuse. Advice and follow up was the most common approach in the recent pediatric cohort (76%).
Trauma patterns in the primary dentition seem to be rather universal due to the activities of small children and their anatomic conditions. Trauma to primary dentition occurred mostly at home or in the nurseries and possibly is hard to avoid due to falls or accidents during normal playing. Even after 30 years and a change in the health care system due to German unification, the patterns remain similar.

Die vorliegende Studie basiert auf der Untersuchung von 89 verschiedenen Säugetierschädeln und 14 menschlichen Schädeln aus dem Institut für Anatomie und Zellbiologie der Universität Greifswald.
Die Arbeit vergleicht die Morphologie der knöchernen Schädel der Säugetiere mit denen des Menschen. Dabei wird von kieferorthopädischen Messpunkten, wie sie beim Menschen bereits seit längerer Zeit angewendet werden, ausgegangen. Sämtliche Messpunkte, die in der Kieferorthopädie herangezogen werden, finden sich auch an den Säugetierschädeln, sodass von einem gemeinsamen Schädelbauplan ausgegangen werden kann. Systematische Untersuchungen an einer größeren Gruppe von Säugetieren mit kieferorthopädischem Ansatz wurden, soweit ersichtlich, bisher noch nicht durchgeführt. Ziel dieser Arbeit ist es damit auch, eine dementsprechende Datengrundlage zu schaffen. Die dreidimensionale Vermessung erfolgte mit dem MicroScribe 3DX Digitalisierer (Immersion Corp., San Jose, CA) sowie einem digitalen Messschieber. Die Schädel wurden entsprechend der in der Literatur angewandten Taxonomie in Gruppen eingeteilt. Aus der Ordnung der Primaten wurden die Hominoidea, Platyrrhini, Cercopithecoidea und Lemuriformes untersucht, bei den Carnivora die Feliformia, Canidae, Ursidae und Pinnipedia. Bei den Cetartiodactyla wurden Ruminantia und Suidae vermessen, bei den Mesaxonia die Equidae.
In einem ersten Teil der Arbeit kommt die klassische Morphometrie zu Anwendung. Dabei werden klassische KFO- Messpunkte wie Nasion, Menton, Gonion, Pogonion, Zygion, Spina nasialis antetior, etc. verwendet, ebenso klassische Indizes wie Bolton-Analyse, Pont- Index und Izard- Index. In einem zweiten Teil kommt die geometrische Morphometrie zur Anwendung. Diese in der Biologie und Anthropologie bereits häufiger angewandte Methode wird jetzt auch vermehrt in der Kieferorthopädie angewandt. Durch die sogenannte Procrustes Transformation können dabei die vermessenen Schädel in Form und Gestalt unabhängig von der Größe verglichen werden. Bei sämtlichen Messungen werden die Unterschiede bzw. Gemeinsamkeiten zwischen Mensch und den einzelnen Säugetierarten herausgearbeitet und tabellarisch und graphisch dargestellt.
So können die beim Menschen nachgewiesenen kieferorthopädischen Indizes auch teilweise bei den Säugetieren gefunden werden. Sowohl beim Izard- Index als auch bei der Bolton- Analyse und der Tonn- Relation können Gemeinsamkeiten festgestellt werden. Größere Abweichungen gibt es dagegen beim Pont- Index, dem Gaumenhöhen- Index und dem Gaumen- Index. Auch der Jugomandibularindex zeigt wenig Übereinstimmung mit dem Menschen.
Dass die Primaten und hier insbesondere die Hominoidea und Cercopithecoidea dem Menschen schädelbezüglich am ähnlichsten sind, war zu erwarten und kann durch die hier vorliegenden Ergebnisse auch bestätigt werden. Allerdings weichen die Primaten bei der Gaumenform stärker vom Menschen ab, während bei der Gesichts- und Kieferform eine weniger zu erwartende Übereinstimmung mit Feliformia und Canidae festgestellt werden kann.
Das evolutionsbedingt stärkste Unterscheidungsmerkmal zu den Säugetieren ist der beim Menschen im Vergleich zur Schädellänge relativ kurze Gesichtsschädel.
Die in der Literatur beschriebene Taxonomie der Säugetiere, die durch eine Vielzahl verschiedener Untersuchungen hervorgegangen ist, kann hier sowohl mit Hilfe der klassischen Morphometrie als auch insbesondere durch die geometrische Morphometrie bestätigt werden. Bei der letzteren wird nach der Procrustes Transformation durch Clusterbildung sowohl nach deutlich voneinander abweichenden, als auch nach in sich homogenen Gruppen differenziert.
Durch die in dieser Studie differenziert herausgearbeiteten anatomische Strukturen in verschiedenen Schädelbereichen würde sich zusätzlich die Möglichkeit ergeben, bei kieferorthopädischen Tierversuchen in kraniofazialen Schädelregionen das anatomisch geeignete Tiermodell zu bestimmen, d.h. nicht eine einzelne Tierart ist für alle Versuche geeignet, sondern je nach Fragestellung müssen in unterschiedlichen Schädelbereichen verschiedene Tierarten herangezogen werden.
Objective: To compare the effectiveness and complications of intraligamentary anesthesia
(ILA) with conventional inferior alveolar nerve block (IANB) during injection and dental
treatment of mandibular posterior teeth.
Materials and Methods: In this randomized, prospective clinical trial, 72 patients (39 males, 33
females) patients scheduled for dental treatment of mandibular posterior teeth, were randomly
allocated to ILA group (n=35) received ILA injection or IANB group (n=37) received the
conventional IANB. Our primary outcome was to assess pain and stress (discomfort) during the
injection and dental treatment, using the Numeric Rating Scale (NRS) from 0 to 10 (0 = no
pain, 10= the worst pain imaginable). Whereas; recording 24 hours postoperative complications
were our Secondary outcomes.
Results: Patients in ILA group reported significantly less pain during injection when compared
with IANB group (p=0.03). While pain during dental treatment was similar in both groups
(p=0.2). Patients in both groups also reported similar low values of discomfort during treatment
(p= 0.7). Although no signs of nerve contact or any other postoperative complications were
observed, five patients in IANB group (none in ILA group) reported temporary irritations
Conclusion: This study showed equivalent effectiveness of both intraligamentary anesthesia
and conventional inferior alveolar nerve block, for pain control during routine dental treatment
of mandibular posterior teeth. Nevertheless, ILA showed significantly less pain during
injection. No major postoperative complications in both groups were observed.
Clinical Relevance: ILA could be considered as an effective alternative for routine dental
treatment.
Hintergrund
Die stetig steigende Anzahl von akademischen Veröffentlichungen macht es zunehmend schwierig, Publikationen zu identifizieren, welche die neuesten wissenschaftlichen Erkenntnisse repräsentieren und es ermöglichen, auf dem neuesten Stand der Forschung und evidenzbasierter Behandlungsempfehlungen zu bleiben.
Ziel
Ziel dieser Studie war es, die Suchstrategien und Auswahlpräferenzen zu untersuchen, die verschiedene akademisch tätigen Zahnärzte bei der Auswahl der fünf bedeutendsten Publikationen aus dem Jahres 2016 im Fachgebiet der Kinderzahnheilkunde verwendeten.
Design
Die fünf an der Studie teilnehmenden Zahnärzte wurden gebeten, ohne untereinander darüber zu kommunizieren, die Datenbanken PubMed, Google Scholar und Livivo zu durchsuchen. Zudem sollten sie dabei ihre individuelle Suchstrategie dokumentieren. Die Aus-wahlkriterien wurden anschließend gemäß einer 10-Punkte-Checkliste evaluiert. Der Evidenzlevel der identifizierten Publikationen wurde anschließend gemäß ihrer Publikationsart bewertet.
Ergebnisse
Alle Studienteilnehmer wählten unterschiedliche Publikationen ohne Überschneidungen aus. Alle von ihnen ausgewählten Publikationen waren Zeitschriftenartikel. Neunzehn Artikel wurden in der Datenbank PubMed identifiziert, jeweils drei Artikel wurden in Google Scholar und Livivo gefunden. Die Relevanz des Artikels für die klinische Entscheidungsfindung war das wichtigste Kriterium bei der Auswahl durch die Teilnehmer.
Fazit
Die persönlichen Interessen und Fachgebiete der Kliniker beeinflussten die Auswahl der Zeitschriftenartikel in erheblichem Maße. Dies könnte die interindividuelle Variabilität der diagnostischen und therapeutischen Ansätze erklären, die bei Zahnärzten beobachtet wer-den kann, und trägt wahrscheinlich zu einer Verbreiterung des Wissenspools bei. Dies wird jedoch richtigerweise durch evidenzbasierte Behandlungsempfehlungen komplementiert, was die Qualität der Behandlung überregional sicherstellt.
