ABSTRACT
The rehabilitation of patients with failing or missing dentition using titanium implants has dramatically changed in the last decades. Despite the predictability of implant therapy, failures that mandate implant removal do occur. The aim of our study was to determine the failure rates of implants placed during the last nine years at the dental clinic of the Faculty of Dental Medicine at Saint-Joseph University, Beirut. 640 individuals received dental implants; failures were clustered in 75 [11.7%] patients [27 men and 48 women, mean age 49.66 +/- 13.4 years]. The total failure rate was 5.68%. Most failures were early [66.3%] and a statistically significant decrease in failure rate was observed during the last years [p=0.003]
ABSTRACT
The purpose of this study is to evaluate, radiographically, the change in intra-sinus graft height after implant placement using inorganic mineral bovine bone and the osteotome technique. Thirty-one implants were placed in twenty-five patients with simultaneous sinus lift using the crestal approach and deproteinized bovine bone [[Bio-Oss[registered sing]]. Periapical radiographs were taken immediately after implant placement, after six months [healing period], and after a minimum of six months of loading. Changes of the graft height were evaluated using image analysis software [Image Tool for Windows, version 3, UTHSCA]. The distance between the implant apex and the graft summit was measured along the longitudinal axis of the implant [distance D]. This distance was consecutively measured on radiographs taken immediately after surgery [D0], at second stage surgery [D6], and at follow-up visits [D12]. Only 25 out of 31 implants were included to analyze the variation in the distance D in [D6 and D12]. Statistical analysis showed a significant difference between D0 and D6 [p<0.0001], between D6 and D12 [p<0.002], and between D0 and D12 [p<0.001]. The graft lost 27.4% of its apical height after twelve months. Within the limitations of the present study it was found that the use of deproteinized bovine bone, which has a very slow resorption rate, could not prevent changes in the initially gained intrasinus graft height. However, the reported results showed that its use was beneficial in limiting the loss of the augmented height to a minimum
ABSTRACT
Various factors are taken into account in assessing objectively the dental status and the quality of life related to oral health, particularly in elderly. Basic socio-demographic characteristics and oral hygiene habits must be identified and screened, respectively. The dental health can be evaluated using indicators such as the ASA score or by determining the person's level of autonomy. Cognitive ability of older people must be checked prior to use oral health questionnaires. This competence can be assessed by the Mini Mental State score [MMS]. The use of Mini Nutritional Assessment [MNA] evaluates the nutritional status of patients. The aim of the article is to identify the most relevant indicators that can be used in epidemiological studies to assess the oral health of Lebanese elderly
ABSTRACT
Recently, several studies showed the influence of periodontitis on systemic diseases. Cardiovascular disease, diabetes, respiratory infections, rheumatoid arthritis and preterm low birth weight could be enhanced by periodontal pathogens. Diagnosis of periodontitis would be important in these patients in order to minimize complications of their systemic conditions. This article will review the etiopathologic mechanism and the therapeutic implications of each affection
