background and aims. furcally-involved teeth present unique challenges to the success of periodontal therapy and influence treatment outcomes. this study aimed to assess to compare use of adm and connective tissue membrane in class ii furcation defect regeneration. materials and methods. 10 patient with 2 bilaterally class ii furcation defects in first and/or second maxilla or man-dibular molar...

marfan’s syndrome (mfs) is a genetic disorder associated with autosomal dominant inheritance. in mfs, the most prevalent cause of death is cardiovascular involvement. here we introduce a family with a severe penetration of mfs. eleven members of this family have mfs (father, two daughters, three sons, and five grandchildren). the most common cardiac involvement in our patients was mitral valve ...

soft tissue-implant interface is an important anatomical feature contributing to the long-term success of dental implants. based on the available evidence, different factors may influence biological width around implants including the surgical technique, implant loading, implant surface properties, abutment materials, implant position, and width of the peri-implant mucosa. the purpose of the pr...

mulla sadra shirazi by his fundamentals like fundamentality of existence, existential gradation and the unity of being, believes that love equals being and explains how the love moves in all particles in the universe. he maintains that love is divine nature of human existence and it is full of wisdom and expediency sees. although the description of love by the theory of fundamentality of existe...

normal pressure hydrocephalus (nph) is characterized by gait apraxia, urinary incontinence, and dementia. mixed connective tissue disease (mctd) is an autoimmune connective tissue disease that has never been reported to cause nph. our patient was a 67-year man with a one-year history of gradual worsening gait and balance, urinary urgency with urge incontinence and decreased short-term memory. p...

We consider a 2-valued non-deterministic connective $${\wedge \!\!\!\!\!\vee }$$ defined by the table resulting from entry-wise union of tables conjunction and disjunction. Being half disjunction we named it platypus. The value is not completely determined input, contrasting with usual notion Boolean connective. call any based on multi-functions over set. In this way, non-determinism allows for...

background and aim: the aim of the present study was to compare coronally advanced flap (caf) with amniotic membrane to caf with connective tissue graft (ctg) in the treatment of miller’s class iⅈ gingival recessions. materials and methods: 11 systemically healthy patients, with 30 miller’s class і and іі gingival recessions ≥3 mm, were selected and randomly divided into two equal groups. gi...

several techniques and materials have been introduced for the treatment of gingival recession defects. this article reports the case of a 43-year old female patient with chief complaint of esthetic problem, presenting multiple gingival recession defects in anterior maxilla. cenoderm combined with coronally positioned flap was used for management of six teeth with gingival recession. complete ro...

Skeletal muscles power a broad diversity of animal movements, despite only being able to produce high forces over a limited range of velocities. Pennate muscles use a range of gear ratios, the ratio of muscle shortening velocity to fiber shortening velocity, to partially circumvent these force-velocity constraints. Muscles operate with a high gear ratio at low forces; fibers rotate to greater a...
