Relationship Of

The host–predator relationship of the myceliophagous nematode Aphelenchus avenue Bastian and the predaceous hyphomycete Dactylaria Candida (Nees) Sacc. was investigated under laboratory conditions, using phase-contrast microscopy of whole-mount preparations and thin resin (Spurr) sections. Adhesive trapping knobs were profusely produced by D. Candida and these proved efficient nematode-trapping agents. Nonconstricting rings were rare and never seen to be operative. Dactylaria Candida was found to be capable of parasitizing nematode eggs.

The aim of this study was to evaluate two different kinds of rough implant surface and to assess their tendency to peri-implantitis disease, with a follow-up of more than 10 years. Data were obtained from a cluster of 500 implants with Ti-Unite surface and 1000 implants with Ossean surface, with a minimum follow-up of 10 years. Implants had been inserted both in pristine bone and regenerated bone. We registered incidence of peri-implantitis and other causes of implant loss. All patients agreed with the following maintenance protocol: sonic brush with vertical movement (Broxo), interdental brushes, and oral irrigators (Broxo) at least two times every day. For all patients with implants, we evaluated subgingival plaque samples by phase-contrast microscopy every 4 months for a period of more than 10-years. Ti-Unite surface implants underwent peri-implantitis in 1.6% of the total number of implants inserted and Ossean surface implants showed peri-implantitis in 1.5% of the total number of implants. The total percentage of implant lost was 4% for Ti-Unite surfaces and 3.6% for Ossean surfaces. Strict control of implants leads to low percentage of peri-implantitis even for rough surfaces dental implants.
