The severity of children's DC has a negative impact on parents' QoL, whereas TDI do not. A lower family income might have a negative impact on parents' QoL.

This in vitro study aimed to assess the speed and caries removal effectiveness of four different new and conventional dentine excavation methods. Eighty deciduous molars were assigned to four groups. Teeth were sectioned longitudinally through the lesion centre. Images of one half per tooth were captured by light microscope and confocal laser scanning microscopy (CLSM) to assess the caries extension. The halves were then reassembled and caries removed using round carbide bur (group 1), Er:YAG laser (group 2), hand excavator (group 3) and a polymer bur (group 4). The time needed for the whole excavation in each tooth was registered. After excavation, the halves were photographed by light microscope. Caries extension obtained from CLSM images were superimposed on the post-excavation images, allowing comparison between caries extension and removal. The regions where caries and preparation limits coincided, as well as the areas of over- and underpreparation, were measured. Steel bur was the fastest method, followed by the polymer bur, hand excavator and laser. Steel bur exhibited also the largest overpreparation area, followed by laser, hand excavator and polymer bur. The largest underpreparation area was found using polymer bur, followed by laser, hand excavator and steel bur. Hand excavator presented the longest coincidence line, followed by polymer and steel burs and laser. Overall, hand excavator seemed to be the most suitable method for carious dentine excavation in deciduous teeth, combining good excavation time with effective caries removal.

The aim of this study was to investigate caries experience in individuals with cerebral palsy (CP) who have oromotor dysfunction and relate it to age and dietary consistency. Noninstitutionalized individuals with CP (n = 108) aged 4-19 years (mean: 10 years, 1 month +/- SD 4 years, 5 months) were recruited for this study. Subjects who were severely impaired (35.2%) had orofacial motor dysfunction most frequently, followed by those who were slightly affected (27.7%), moderately affected (20.4%), and very slightly affected (16.7%). Age was a statistically significant factor for oromotor dysfunction (p= 0.007), with the youngest individuals having the most severe oromotor problems. Dietary consistency and oromotor function were statistically significant influence on the DMF index (p= 0.0352). The highest total DMF values were measured for individuals who were severely impaired and also the youngest, as well as for those receiving liquid diets. Early rehabilitation, intervention, and prevention are important for these individuals.

The results suggest that caregivers of CP individuals exhibited worse quality of life than those of the non-disabled. A negative correlation exists between caries experience of CP individuals and their caregivers' quality of life.

The Program is effective on reducing the incidence and promoting regression of initial caries lesions in children.
