The Importance of the OHI-S for Children with Premature Tooth Loss

Radosveta Andreeva, Ani Beltcheva


In spite of all methods of prevention, there are still untreated or improperly treated caries and it`s complications. This often leads to early loss of teeth.

The early loss of the deciduous teeth depends on different reasons such as oral hygiene, traumas, complicated carious .The aim of this study is to compare the OHI S between children with premature loss and those without premature loss of deciduous teeth. Subject of monitoring of the clinical research were 140 children between 6 and 9 years old.  The clinical group consists of 90 children with prematurely extracted teeth, divided into three groups. The control group consists of 50 children with intact denture. The oral hygiene status was examined and registered by the Greene-Vermillion index-simlified. There was a statistically significant difference in the OHI-S between the control group (1.86±0.05) and clinical groups (1.90±0.08 and 2.01± 0.05). The children with  premature  extraction of the primrary  teeth  have a higher  OHI-S  compared to the control group (children without premature extraction of teeth). The third group children, with prematurely extracted temporary teeth and severe orthodontic deformation have the highest OHI-S. This results demonstrates the connection between OHI, the orthodontic deformations  and the prevention need.
