Abstract
Background In an era of precision and stratified medicine, homogeneity in population-based cohorts, stringent causative entry, and pattern analysis of datasets are key elements to investigate medical treatments. Adhering to these principles, we collected in vivo and in vitro data pointing to an insulin-sensitizing/insulin-mimetic effect of myo-inositol (MYO) relevant to cell regeneration in dentistry and oral surgery. Confirmation of this possibility was obtained by in silico analysis of the relation between in vivo and in vitro results (the so-called bed-to-benchside reverse translational approach). Results Fourteen subjects over the 266 screened were young adult, normal weight, euglycemic, sedentary males having normal appetite, free diet, with a regular three-times-a-day eating schedule, standard dental hygiene, and negligible malocclusion/enamel defects. Occlusal caries were detected by fluorescence videoscanning, whereas body composition and energy balance were estimated with plicometry, predictive equations, and handgrip. Statistically significant correlations (Pearson r coefficient) were found between the number of occlusal caries and anthropometric indexes predicting insulin resistance (IR) in relation to the abdominal/visceral fat mass, fat-free mass, muscular strength, and energy expenditure adjusted to the fat and muscle stores. This indicated a role for IR in affecting dentin reparative processes. Consistently, in vitro administration of MYO to HUVEC and Swiss NIH3T3 cells in concentrations corresponding to those administered in vivo to reduce IR resulted in statistically significant cell replication (ANOVA/Turkey tests), suggesting that MYO has the potential to counteract inhibitory effects of IR on dental vascular and stromal cells turnover. Finally, in in silico experiments, quantitative evaluation (WOE and information value) of a bioinformatic Clinical Outcome Pathway confirmed that in vitro trophic effects of MYO could be transferred in vivo with high predictability, providing robust credence of its efficacy for oral health. Conclusion Our reverse bed-to-benchside data indicate that MYO might antagonize the detrimental effects of IR on tooth decay. This provides feasibility for clinical studies on MYO as a regenerative factor in dentistry and oral surgery, including dysmetabolic/aging conditions, bone reconstruction in oral destructive/necrotic disorders, dental implants, and for empowering the efficacy of a number of tissue engineering methodologies in dentistry and oral surgery.

Abstract
In den letzten 8 Jahren wurde in Deutschland nicht nur „mehr Versorgungsforschung in der Zahnmedizin“ gefordert, sondern auch geleistet. Insgesamt finden sich an 12 Medizinischen Fakultäten themenbezogene Aktivitäten der Zahn‑, Mund- und Kieferheilkunde in der Versorgungsforschung; deutschlandweit werden 9 Großprojekte verortet, die vom Bundesministerium für Bildung und Forschung oder vom Innovationsfonds gefördert werden. Gleichwohl ist der Bedarf an Versorgungsforschung größer als die jetzige Leistungsfähigkeit der universitären und außeruniversitären Zahnmedizin: Um eine nachhaltige, bedarfsgerechte und zukunftssichere zahnärztliche Versorgung aller Menschen in Deutschland gewährleisten zu können, bedarf es strukturierter, methodisch versierter und in die Versorgung hinein vernetzter Verbünde, die das wissenschaftliche Fundament für erwartete Versorgungsumbrüche legen können. Der vorliegende Beitrag soll den Stand der Versorgungsforschung in der Zahn‑, Mund- und Kieferheilkunde in Deutschland beschreiben. Die wesentlichen Herausforderungen werden adressiert: Methodenkompetenz, Zugang zu Daten und deren Nutzung sowie die langfristige Perspektive dieses Forschungsbereichs. Derzeitige Forschungsaktivitäten und Infrastruktur inklusive Förder- und Fortbildungsinstrumente werden dargestellt. Die Erkenntnisse aus der zahnärztlichen Versorgungsforschung in Deutschland können auch für andere Länder richtungsweisend sein; umgekehrt kann Versorgungsforschung Ansätze aus anderen Ländern sinnvoll in das deutsche Gesundheitssystem übertragen. Versorgungsforschende sollten sich professionalisieren und vernetzen. Nachhaltige Strukturen (Professuren, Mittelbau) und Rahmenbedingungen (Datennutzung, Förderung) sollten geschaffen und Forschungsergebnisse zeitnah verwertet werden.
