The law of dental implant
No full textAlthough Oral Implantology has been a tremendous innovation in dentistry and has radically changed our profession and the quality of treatment we can provide, the current dental scientific and clinical knowledge shows that there are multiple alternative treatment options prior to opting for extractions and implant supported restorations 12-14 .Moreover, as clinicians and researchers, we do know that dental implants are not free of biological and technical complications15 , which often are more difficult to deal with than that of teeth
The impact of smoking and previous periodontal disease on peri-implant microbiota and health: a retrospective study up to 7-year follow-up.
Full text linkAIM: To evaluate the impact of smoking and previous periodontal disease on peri-implant microbiota and health in medium to long-term maintained patients.
METHODS:
A retrospective evaluation of partial edentulous patients restored with dental implants and enrolled in a regular supportive therapy was performed. Inclusion criteria were: medium to long-term periodontal and implant maintenance (at least 5 years), a minimum of 2 implants placed in each patient, absence of systemic diseases that may affect osseointegration. 30 implants in 15 patients were included in the study. Subjects were divided in smokers or non-smokers and between patients previously affected by periodontal disease and periodontally healthy. Peri-implant and periodontal parameters were assessed (PD,BoP, mPI). Microbiological samples were collected around implant and an adjacent tooth. Real- Time Polymerase Chain Reaction (RT-PCR) analysis was performed.
RESULTS:
In all the three groups no differences in bacterial counts between dental and implant sites were observed. Non smoker, healthy patients: healthy clinical parameters, significant counts of spirochetes in isolated patients. Non smokers with previous periodontal disease: occasional positive BoP values, significant high counts of pathogenic bacteria. Smokers with previous periodontal disease: clinical signs of inflammation including deep pockets and slight bone resorption, significant counts of pathogenic bacteria.
CONCLUSIONS:
Over a follow-up of 5 to 7 years, it is possible to state that the absence of smoking habit and previous periodontal disease positively influences the peri-implant microbiological and clinical conditions in partial edentulous patients restored with dental implants and enrolled in a strict regular supportive therapy

Allergy and desensitization to latex. Clinical study on 50 dentistry subjects.
No full textAIM: Nowadays latex allergy represents a relevant social and occupational problem because this substance constitutes the first material to realise many dental and non dental products; then, there is a cross-reactivity between latex allergens and proteins present in many vegetal foods. The aim of our research was to find latex allergy cases experimenting a percutaneous desensitization protocol. METHODS: Among 50 examined subjects, those patients resulting positive to thiuram-mix by patch test have been submitted to desensitization after removal of all latex products and substances giving cross-allergy (kiwi, celery, chestnuts, tomato, banana etc.). Desensitization has been carried out by using latex glove from 10 s progressively to 1 h after 1-year treatment. RESULTS: In 7 patients out of 11 (63.6%) regression of symptoms has been verified; 2 patients (18.2%) have declined treatment and 2 patients (18.2%) have showed no regression. CONCLUSIONS: Apart immunotherapy and DNA-vaccines, nowadays percutaneous desensitization is the most efficacious, safe and easy treatment for latex allergic patients; it has no collateral effects during its execution and no symptoms coming back to work, but it needs further verifications
