Background/purpose
The aim of this prospective randomized controlled clinical trial was to compare vertical bone gain and bone resorption after sinus graft procedures performed either with particulate or with autogenous bone block.
Material and methods
Forty-one patients underwent sinus graft procedures with autogenous bone. They were randomly assigned to one group. The first group of 22 patients was treated with autogenous bone block with or without particulated bone, while in the second group of 19 patients sinus floor elevation was performed only with particulated autogenous bone. Linear measurements were recorded before surgery with a computed tomography scan at surgery and at 36 months after sinus lift grafting with a second computed tomography scan. To detect statistical differences Student
t
test was applied. Differences were considered significant if P values were < 0.05.
Results
There was a statistically significant difference in bone gain for the group treated with bone block grafts.
Conclusion
As a general clinical guideline the clinician should prefer, wherever feasible, en-block bone grafts for sinus floor augmentation procedures.
Purpose: to value efficacy of anti microbic propriety of silver ligatures Orthoshield Safe-T-Tie® on periodontal tissues in orthodontic patients. Materials and methods: 50 orthodontic patients between 11 and 20 years old with permanent teeth were selected in this study. We evaluated periodontal health of maxillary and mandibular lateral incisors and canines at TO before the substitution of elastomeric ligatures with Orthoshield Safe-T-Tie® ligatures and at T1 (one month after substitution of ligatures). We used PI (Periodontal Index), GI (Gingival Index) and PRC-real-time to analyze periodontal health. Results: there was an improvement of gingival inflammation and a reduction of periodontal pathogens. Conclusions: Orthoshield Safe-T-Tie® ligatures improve periodontal health in orthodontic patients.
Dentists both as clinical practice and research increased progressively their interest in leukemia, because the oral complications are common during the outcome of the disease, dental management is complex, and the mouth is a potential source of morbidity. The aim of this review is analyzing the most important periodontal problems due to childhood Leukaemia. Infact only with an appropriate periodontal treatment oral health could be mantained and restored before development of irreversible periodontal damage. Our experience suggests that even if detrimental impact of antineoplastic therapy on oral cavity is unavoidable, it could be diminished with an adequate and correct preventive or curative therapy contributing to a better quality of life of children treated for cancer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
