Influence of bisphosphonates and mechanical loading on periostin synthesis of periodontal fibroblasts (HPdLF)The orthodontic dreatment of adult patients is getting more and more popular. Patients with osteoporosis and intake of bisphosphonates are a new challenge for orthodontic treatment. For the orthodontic tooth movement bone-turnover of the alveolar bone is necessary and induced by the applied forces on the teeth. The periodontium and the alveolar bone reacts with bone apposition and resorption. Bisphosphonates do also influence these mechanism of burn turn-over. Periostin is an important adhesionsprotein supporting the cell-matrix-contacts. It plays an important role in the regulation of the remodelling of the periodontium. Aim of this study is to analyze the effects of mechanical loading and bisphosphonates on the periostin synthesis of HPdLF.

A Digital Plaque Imaging Study to Assess the Anti-Plaque Efficacy of Two Marketed DentifricesAbstract: The objective of this study is to assess plaque after using two marketed dentifrices by means of DPIA. This is a single-center, 2-treatment, blinded, parallel group, randomized study design. A sufficient number of adults ages 18+ will be screened to enroll 100 subjects (50 per treatment group) at the acclimation visit. Subjects will have a baseline visit at which they will have an oral soft tissue exam (OST), and one replicate of pre and post brushing DPIA images taken. Then, subjects will be stratified and randomly assigned to one of the two treatment groups at the Product Distribution visit based on DPIA plaque measurements taken at the Baseline visit. After three weeks of treatment, subjects will have two additional separate visits and will have one replicate of pre and post brushing DPIA images taken at each visit

An Exploratory Study to Assess Plaque Reduction of Two Marketed DentifricesThe objective of this study is to assess plaque (primary variable) and salivary metabolites (secondary variable) after using two marketed dentifrices.
This is a randomized, two-treatment, cross-over study with four treatment periods. Up to 36 healthy adult volunteers who have evidence of overnight plaque will be enrolled. Evidence of overnight plaque is based on a screening exercise. Subjects will complete approximate 2 week acclimation period, followed by a 17 days treatment period, and then a 4 day wash-out period. Overnight plaque will be measured by digital plaque image analysis of fluorescein-disclosed plaque. Saliva samples will be collected during acclimation and during the third treatment week of each treatment period. The treatment and wash-out periods will be repeated until Period 4 is complete. Subjects will be randomly assigned to one of four treatment sequences at the Product Distribution visit before Period 1.

Biofilm characterization from people with different mechanical Plaque removal profileThis was a single-center, double-blind, 2-week, 1-treatment, parallel group study design. Thirty-nine (39) adult subjects, who showed evidence of dental plaque and who were routine manual toothbrush users were enrolled in this study and scheduled for a professional brushing visit. Subjects were instructed to refrain from all oral hygiene procedures for approximately 24 hours prior to their appointments. Of the initial 39, 20 subjects with repeatable plaque levels (at visits 1 and 2) were categorized to have either “hard-to-remove” or “easy-to-remove” plaque (10 subjects each) based on their professional-brushing plaque removal values and were selected for 3 more visits.On-site toothbrushing between pre- and post-brushing plaque assessments were standardized and performed by a dentist. Plaque was measured using DPIA (Digital Plaque Imaging Analysis). At visits 3 to 5 clinical specimens (supragingival plaque samples) were collected from the 20 selected subjects and stored following established techniques for subsequent analysis outside the study protocol. The plaque samples were analyzed for bio-mechanical, compositional and structural properties. At visit 3 subjects received a dental prophylaxis. Approximately 2 weeks later, subjects were invited to measure plaque levels using DPIA. Then they received a professional brushing after which post-brushing DPIA images were taken. Dental plaque was resampled and analyzed for endpoints mentioned above. Subjects then received treatment products (regular manual toothbrush and antibacterial fluoride toothpaste) to use at home for the next 2 weeks. At subject’s final visit (visit-5), the same assessments were conducted as for visit 4.Subjects completed a pre and post-treatment questionnaire about their nutrition behavior. |

Clinical Study to assess the Plaque removal efficacy of a new manual toothbrush with small brush headStudy Objective
The objective of this study was to evaluate the efficacy of a new Oral-B manual toothbrush (Cross Action small brush head design) verus a control group (Oral-B Indicator 30 soft) in the reduction of dental plaque among a general adult population using the Turesky Modified Quigley-Hein Index (TQHPI).
Product Usage
Acclimation:
Subjects were instructed to brush their teeth at home twice daily (morning and evening) in their customary manner using the assigned provided test toothbrush and their regular toothpaste for approximately one week prior to their on-site visits.
Periods 1-4
Subjects were instructed to brush their teeth as they normally do with the assigned manual brush. The marketed dentifrice was dispensed by site personnel on a tongue depressor. Subjects brushed their teeth without access to a mirror. Brushing time was recorded in a discrete manner by site staff.
Study Design
This was a single-brushing, 2-treatment, examiner-blind, randomized, 4 period, crossover design. Subjects used each of the two toothbrushes twice. 26 adult subjects were enrolled into the clinical trial based on study criteria. For familiarization purposes, subjects were given their assigned test toothbrush to use at home twice daily for approximately one week prior to each study period visit. Subjects were instructed to refrain from all oral hygiene procedures for approximately 24 hours prior to each of their appointment times. In addition, the subjects were instructed to refrain from eating, drinking, chewing gum or smoking (including smokeless tobacco) for 2 hours prior to their appointment time. Only small sips of water were permissible. Subjects were to refrain from sipping water 45 minutes prior to their scheduled visit.

Histological and histomorphometric investigation of the median palatine suture in different age groups - an ex vivo study on human cadaver specimensThe median palatine suture of the maxilla, which extends from the maxillary incisal fossa to the nasal posterior spine, is of great clinical importance and relevance to orthodontists worldwide. A rapid maxillary expansion (RME) is indicated in the presence of a a narrow upper jaw and / or a one- or bilateral crossbite and / or frontal crowding in order to create space as fast as possible in the transversal.
As the patient ages, the so-called transversal resistance of the median palatine suture becomes larger and thus, it becomes increasingly difficult to predict the success of a conservative RME. Therefore, in patients > 18 years, surgically assisted RME is usually preferred to conservative RME.
Assumptions that the increasing ossification of the suture are responsible for this resistance can only be partially verified. Previous studies showed that at the age of 30 years, only a very small portion of the median suture is clearly ossified, which means that there is still a need for considerable examinations / ex vivo studies.
The aim of this study is to use modern histological and histomorphometric methods to analyze the age-related morphological changes of the median palatine suture in cooperation with Prof. Dr. Dr. Dr. Shahram Ghanaati, Senior Consultant and Head of the Research Laboratory (FORM-Lab, Frankfurt Orofacial Regenerative Medicine-Lab), the Department of Oral and Maxillofacial Surgery of the Goethe-University Frankfurt am Main (Director: Univ.-Prof. Dr. Dr. Robert Sader). Further insights into the transversal resistance of the median palatine sutura should be gained. The working hypothesis says that the age-dependent form changes of the suture, the horizontal and transversal interdigitations (twisting or toothing of the bone suture), respectively, could be responsible for this resistance.

Study evaluating the oral hygiene status and quality of life of the patient before, during and after the Aligner-Therapy (Invisalign®)The German Oral Health Study IV (DMS IV) from 2005 shows that for 45% of children (age: 12 years) and 58% of adolescents (age: 15 years) an orthodontic treatment has either been carried out or was planned. In addition, a clear decline in the incidence of caries in children and teenagers was reported. 70.1% of the children (age: 12 years) and 46.1% of teenagers (age: 15 years) had caries-free teeth. Nearly 80% of caries cases were experienced by only 26.5% of the teenagers (age: 15 years) (Brauckhoff et al. 2009) [1]. In the overall patient population of the Department of Orthodontics at the Medical University of Mainz, about 80% of patients are treated with fixed orthodontic appliances. Aligner Therapy is also a contemporary procedure for orthodontic treatment. In 2011, approximately 78.000 patients worldwide were treated by Invisalign teen. Dental plaque plays an important role in the development of caries and oral disease. Plaque removal and control are important aspects of oral health establishment and maintenance (Shibly et al., 1995)[2]. Plaque can cause dental demineralisation (WSL - White Spot Lesions), a prerequisite for the onset of caries, and lead to gingivitis (Gorelick et al., 1982, Oogaard B, 1989, Årtun and Brobakken, 1986) [3-5]. Therefore, the main objective of this proposed controlled clinical trial is to assess the quantity of WSL between an aligner treatment group (Invisalign teen) and a control group wearing fixed orthodontic appliances. This study is designed as a prospective, controlled, single-treatment study with 7 study visits. Up to 50 subjects with no history of orthodontic treatment will be enrolled into the study. Subjects who meet the inclusion and exclusion criteria will receive a comprehensive oral examination (OST) to evaluate the oral and perioral region, including hard and soft tissues. Overnight plaque accumulation will be evaluated by means of the modified Quigley Hein Plaque Index (TMQH) at each visit. Gingival Crevicular Fluid (GCF) samples will be collected at Baseline (Screening), 4 weeks, 6 months, 1 year and 1 ½ year after receiving first aligner, 3 months after aligner therapy and 1 year after finishing the aligner therapy. Gingivitis-Index (GI) will be assessed at the same time points as the GCF collection. Quantitative Light Induced Fluorescence (QLF) and White Spot Lesion-Index (WSL) will be assessed at visit 1, 6 months, 1 year and 1 ½ year after receiving first aligner, 3 months after aligner therapy and 1 year after finishing the aligner therapy.

Zahn- und Kieferstatus bei Erwachsenen mit Trisomie 21, Ethikkommission der LÄK Rheinland-Pfalz 837.379.14 (9618)Projektskizze: In der Literatur finden sich nur spärliche Angaben über die Häufigkeit zahnärztlicher und kieferorthopädischer Befunde bei Erwachsenen mit Trisomie 21 (Desai 1997; Pilcher 1998). Zum Teil wurden Daten im Rahmen der Untersuchung von allgemein geistig- und/oder körperlich behinderten Menschen erhoben, so dass keine differenzierten Ergebnisse der Gruppe mit Down-Syndrom zu ersehen sind (Dinesh, Arnitha et al. 2003; Winter, Baccaglini et al. 2008).
104 Erwachsene (ab 18 Jahre) mit Trisomie 21 werden klinisch untersucht und bei genügender Kooperation fotografisch dokumentiert.
Es werden bei den Probanden der Gebissbefund (Zahnanzahl, persistierende Milchzähne), sowie der kieferorthopädische (Kreuzbisse, Overbite, Overjet, Engstand oder Lückenbildung, Angle-Klasse) und funktionelle Befund (offene Mundhaltung, Schluckmuster, Zungenlage) erhoben. Außerdem erfolgt eine Befragung der Betreuungspersonen bezüglich zahnärztlicher und kieferorthopädischer Anamnese. Evtl. vorliegende zahnärztliche Röntgenaufnahmen werden angefordert und gescannt.
Anschließend erfolgt bei genügender Kooperationsbereitschaft der Probanden eine intra- und extraorale fotografische Dokumentation.
Die Prävalenz der Einzelbefunde bei den Erwachsenen mit Trisomie 21 soll mit der Prävalenz der Befunde, wie sie in Study of Health in Pomerania (SHIP) 2004 (Hensel, Born et al. 2003) und anderen Literaturstellen (Van der Linden 1983; Harzer 2002; Watted and Teuscher 2003) festgestellt wurden, verglichen werden. Zusätzlich zu den Punktschätzern sollen 95%-Konfidenzintervalle bestimmt werden.

Prospektive Studie zur Untersuchung der Lebensqualitöät von Müttern innerhalb des ersten Jahres nach der Geburt eines Kindes mit Lippen-Kiefer-Gaumenspalte, Ethikkommission der LÄK Rheinland-Pfalz 837.055.17 (10889)Projektskizze: Das Ziel der geplanten multizentrischen Studie ist die prospektive Einschätzung der mütterlichen Lebensqualität, des Kohärenzgefühls und der sozialen Unterstützung nach der Geburt eines Kindes mit Lippen-Kiefer-Gaumenspalte. Der zu erfassende Zeitraum des ersten Lebensjahres stellt unserer Erfahrung nach für die betroffenen Eltern eine enorme Belastung dar. Auch weisen Vorbefunde auf die massive Belastung der Eltern von Kindern mit LKG-Spalte hin. Diese gerade für die Entwicklung der Mutter-Kind-Beziehung sensible Phase der ersten zwölf Lebensmonate wird durch die schwere Gesichtsfehlbildung von Kindern mit LKG-Spalten erheblich gestört.
Um Änderungen der mütterlichen Lebensqualität innerhalb des ersten Lebensjahres des Kindes zu erfassen, werden die Daten zu drei verschiedenen Messzeitpunkten erhoben. Zusätzlich erfolgt ein Vergleich mit einer Kontrollgruppe. Hierfür werden Mütter, die ein gesundes Kind zur Welt gebracht haben befragt. Der Vergleich soll mögliche Unterschiede der beiden Gruppen aufzeigen.
Die gesammelten Daten werden zur Analyse des Behandlungsablaufes sowie zur Einschätzung der Versorgungssituation der betroffenen Mütter herangezogen.

Zahn- und Kieferstatus bei Patienten mit KleinwuchsProjektskizze: Außer Einzelfallbeschreibungen weist die wissenschaftliche Literatur keine Erhebungen zur Häufigkeit Zahn- und Kieferfehlstellungen bei kleinwüchsigen Patienten auf. Im Rahmen des jährlichen Kleinwuchsforums des BKMF in Hohenroda sollen die entsprechenden Befunde erhoben werden. Ziel der Untersuchung ist es, aufgrund einer breiteren Datenbasis die typischen wachstumsbedingten kieferorthopädischen Problemfelder bei den verschiedenen Krankheitsbildern zu eruieren.

Zahnzahlanomalien bei Patienten mit LKG-Spalten im Patientengut der Universitätsmedizin MainzProjektskizze: Die Prävalenz von Zahnnichtanlagen bei Patienten mit LKG-Spalten wird in der Literatur sehr unterschiedlich von 22 bis 86 % angegeben. In der vorliegenden Studie am Patientengut der Universitätsmedizin Mainz sollte untersucht werde, auf welche Orte sich A- und Hypoplasien verteilen und, ob diese Zahnzahlanomalien Einfluss auf die spätere kieferorthopädische und prothetische Therapie (kieferorthopädischer Lückenschluss versus prothetischer Ersatz) haben.
Die Unterlagen (Röntgenbilder; Krankenakten) von 356 Patienten mit Spaltbildung der Geburtsjahrgänge 1954-2007 wurden zufällig dem Archiv der Poliklinik für Kieferorthopädie der Universitätsmedizin Mainz entnommen. Es erfolgte die Extraktion der Parameter: Spaltart; Orte und Anzahl der Hypoplasien und Aplasien; Zeitpunkt der Operationen; Angle-Klasse, Overjet und Overbite zu Beginn der kieferorthopädischen Behandlung; Art der Therapie (prothetischer versus kieferorthopädischer Lückenschluss; Art der prothetischen Versorgung; Notwendigkeit von Umstellungsosteotomien). Die Berechnung der deskriptiven Statistik erfolgte mit dem Programm SPSS23.
