introduction: dental pulp-derived mesenchymal stem cells (mscs) have emerged as a promising tool for use in regenerative medicine. the in vitro growth kinetic and culture requirement of the cells derived from human dental pulp, which is the subject of this present study, is poorly described. materials and methods: stem cells were derived from human third molar and then characterized. the in vit...
introdouction: impacted mandibular third molar surgery may affect periodontal status of the adjacent second molar. the purpose of this study was to evaluate the changes in periodontal health parameters distal to the adjacent second molar following surgical extraction of an impacted mandibular third molar. materials and methods: we selected 50 subjects with a mean age of 22.8 (ranging from 18 to...
objective: the present study assessed the association of size, axial angulation, developmental stage and bud position of the mandibular third molar with the second molar impaction in patients with mandibular second molar impaction. methods: in this descriptive-analytical study (case-control design), dental records of 5,420 patients in the age range of 12-15 years who underwent orthodontic treat...
abstract the third millennium has started, but the world is facing with serious challenges in achieving international security and peace. various human rights violations have lead the states to find means to protect human rights. also article 55 of the united nations charter introduces the respect to human rights and fundamental freedom as the most suitable ways to realize peace and security. ...
introduction based on previous researches, dental pulp stem cells (dpscs) are easily accessible with limited morbidity after collection. their embryonic origin, from neural crests, explains their multipotency. dpscs are primarily derived from the pulp tissues of the teeth.objective: this study was undertaken to isolate, culture, and characterize two different third molar and first premolar huma...

Background and Aims: One of the common human evolutionary anomalies is dental Missing. Evolution of dental system is toward deduction of teeth number. The Missing of third molar is interesting subject for dentists and genetic researches because of its variety in different races. Consideration of bilateral effect of third molar Missing with jaw relation is an important subject. The aim of this s...
background and aims. the surgical removal of the lower third molars is a procedure generally followed by side effects such as postoperative pain. the aim of this study was to evaluate the efficacy of socket irrigation with an anesthetic solution in relieving pain following impacted third molar surgery. materials and methods. thirty-four patients (17 males and 17 females), aged 18-24 years, with...
objective: the aim of the present study was to histopathologically evaluate follicular tissues of third molars with pericoronal radiolucenciesof less than 2 millimeters. materials and methods: in this descriptive analytic study, 100 impacted third molars with normal follicular spaces were removed and their pericoronaltissues submitted for histopathologic examination. different characteristicsof...
