Peri-implant bone loss around posterior mandible dental implants placed after distraction osteogenesis: preliminary findings.

Background: The present study evaluates implant survival and peri-implant bone loss around posterior mandible dental implants placed at sites of distraction osteogenesis.

Methods: On removal of the distraction devices, 34 dental implants were inserted into 14 posterior mandible sites in 10 healthy, non-smoking female patients. Prosthetic treatment was performed 4 months after implant placement using fixed implant prostheses.

Influence of rinsing and expectoration after toothbrushing on fluoride dose and ingested amount by use of conventional and children's fluoride dentifrices.

The purpose of this study was to assess the amount of ingested fluoride and the fluoride dose to which children are subjected during toothbrushing with a conventional dentifrice (1500 ppm F) and a children's dentifrice with special flavor (1100 ppm F) and evaluate the influence of rinsing and expectoration after brushing. Six brushings followed by 6 residue collections (3 per dentifrice) were performed by 42 Brazilian children (aged 20 to 30 months). The concentration of fluoride in the residues and dentifrices was determined.

Fluoride intake by Brazilian children from two communities with fluoridated water.

Objectives: To determine total daily fluoride intake by young children from two communities in a developing country.

Methods: Fluoride intake from diet and dentifrice was determined for 71 Brazilian children, aged 19-38 months, living in two communities with fluoridated water (0.6-0.
