Significance of the D4MF( T+t) index for the children with prematurely extracted teeth

Radosveta Andreeva, Dobrina Karayasheva


The premature loss of the primary teeth is due to different factors like, the level of caries activity, oral hygiene, presence of fluoride in water, socio-economic status of the population, the philosophy of  the dentist (3).The aim of this article is to compare the D4MF (T+t) index 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 dental  status  was examined and registered according to the WHO by D4MF( T+t) index. There was a statistically significant difference in the D4MF( T+t) index between the control groups(1.40±0.13 ) and clinical groups(4.68±0.33, 4.90±0.41 and 5.76±0.41 ) The children with premature extraction of the temporary teeth have a higher caries activity with significantly more complicated carious lesions  compared to the control group(children without early loss of teeth). The children from the third group, with prematurely extracted temporary teeth and severe orthodontic deformation have the highest prevalence of D4MF (T+t). This results demonstrates the connection between D4MF (T+t). , the malocclusions and the need of prophylaxis.
