Effects of high sucrose cariogenic diets with varied protein-calorie levels on the bones and teeth of the rat

  • Marjorie W. Bunyard
Original Papers


The systemic effects of high sucrose cariogenic diets and dental changes other than caries induction were studied in rats. Diets were evaluated for protein quantity and quality in terms of NDpCal %. The molar teeth were smaller and weighed less than normal. Incisor teeth lost the usual orange pigmentation, and the mandible and femur were smaller in size than normal. These changes were present to a less marked degree when the cariogenic diet was of a nutritional standard liekly to be accepted as “adequate” unless special investigations were made. It is suggested that in order to exclude borderline protein-calorie deficiency and side effects influencing mineralisation processes, precautions are necessary in the use of high sucrose diets.

Les effets généraux de régimes cariogènes, riches en saccharose, ainsi que les altérations dentaires, autres que la carie, ont été étudiés chez le rat. Les régimes sont testés pour leur contenu protéique et leur qualité en terme de NDpCal %. Les molaires sont plus petites et pèsent moins que les témoins. Les incisives perdent leur pigmentation orange et le fémur et la mandibule sont diminués de taille. Ces changements s'observent moins nettement, lorsque le régime cariogène présente des qualités nutritives «acceptables» à moins d'effectuer des recherches particulières. Pour éviter des déficiences en protéines et calories, ainsi que des effets secondaires, altérant le processus de minéralisation, il semble nécessaire d'être prudent en utilisant des régimes riches en saccharose.


Die Ganzkörperwirkung von sucrosereichen, karieserzeugenden Nahrungen sowie die nicht durch Karies hervorgerufenen Zahnveränderungen wurden an Ratten untersucht. Die Nahrungen wurden auf ihren quantitativen und qualitativen Proteingehalt geprüft, ausgedrückt als „Nettoprozent der Kalorien entsprechend den Nahrungsproteinen” (Net Dietary Protein Calories Per Cent). Die Molare waren kleiner und leichter als normal. Die Schneidezähne verloren ihre übliche orangefarbene Pigmentation. Mandibula und Femur waren kleiner als normal. Diese Veränderungen fanden sich weniger ausgeprägt, wenn man die kariogene Nahrung so zusammensetzte, daß sie als „adaequat” gelten konnte, außer wenn ganz spezielle Prüfungen vorgenommen wurden.

Es wird vorgeschlagen, daß bei Anwendung hochdosierter Sucrose-Nahrungen Vorsichtsmaßnahmen nötig sind, um einen möglichen Mangel an Proteinkalorien sowie Nebenwirkungen, die den Mineralisationsprozeß beeinflussen, ausschließen zu können.
