introduction: nowadays the necessity of the existence of a certain width of keratinized gingiva is emphasized upon to maintain periodontal health and prevent soft tissue recession around teeth and dental implants. this study was carried out to compare two gingival graft procedures including connective tissue graft and graft with a combination of collagen sponge with platelet-rich plasma and pla...

background: cardiac involvement in systemic sclerosis (ssc) is more prevalent than previously thought. in this study, the frequency and severity of cardiovascular involvement were assessed in ssc patients referred to firouzgar hospital. methods: fifty-eight patients with ssc, selected from the data bank of ssc patients, were reviewed for the frequency and severity of 8 organ involvements in thi...

stem cells are of great interest for regenerating disturbed tissues and organs. these cells are commonly isolated from the bone marrow, but there has been interest in other tissues in the recent years. in this study, we evaluated the possibility of isolation of stem cells from oral connective tissue and investigated their characteristics.in this experimental study, sampling from the bone marrow...

objective: different surgical procedures have been proposed for the treatment of gingival recessions. the goal of this study was to compare the clinical results of gingival recession treatment using subepithelial connective tissue graft and an acellular dermal matrix allograft. materials and methods: the present study was performed on 5 patients with 9 bilateral miller`s class i or ii gingival ...

In this paper we continue development of formal theory of a special class offuzzy logics, called EQ-logics. Unlike fuzzy logics being extensions of theMTL-logic in which the basic connective is implication, the basic connective inEQ-logics is equivalence. Therefore, a new algebra of truth values calledEQ-algebra was developed. This is a lower semilattice with top element endowed with two binary...

background and aims. connective tissue grafts with and without periosteum is used in regenerative treatments of bone and has demonstrated successful outcomes in previous investigations. the aim of present study was to evaluate the effectiveness of connective tissue graft with and without periosteum in regeneration of intrabony defects. materials and methods. in this single-blind randomized spli...

background: localized alveolar ridge defect may create physiological and pathological problems. developments in surgical techniques have made it simpler to change the confi guration of a ridge to create a more aesthetic and more easily cleansable shape. the purpose of this study was to compare the effi cacy of alveolar ridge augmentation using a subepithelial connective tissue graft in pouch an...
