introduction: dental malpractice is the failure of a professional person to render appropriate services through reprehensible ignorance or negligence or through criminal intent, especially when injury or loss follows. since dental implants have gained a special place in modern dentistry and this new treatment is a costly one, paying more attention to the prevention of malpractice is more import...

high variability in delivering the target torque is reported for friction-style mechanical torque limiting devices (f-s mtlds). the effect of aging (number of use) on the accuracy of these devices is not clear. the purpose of this study was to assess the effect of aging on the accuracy (±10% of the target torque) of f-s mtlds.fifteen new f-s mtlds and their appropriate drivers from three differ...

conclusions based on the clinical and radiographic examinations, implant-tooth approximation (less than 1 mm or direct contact) is not related to pulp vitality of the tooth. further studies with larger sample sizes are necessary to confirm the results of the study. results among the 31 assessed implants and the adjacent intact teeth, 13 implants had direct contact and 18 implants had proximity ...

purpose: to compare the rate of fibrovascular ingrowth between primary and secondary orbital implants at varying time intervals after implantation. methods: we prospectively compared the rate of fibrovascular ingrowth between primary and secondary implants by mri and scinitigraphy in patients who underwent orbital implant surgery, 6 months after the operation. results: overall 103 patients unde...

UNLABELLED Endometrial hyperplasia is a precursor to the most common gynecologic cancer diagnosed in women: endometrial cancer of endometrioid histology. It is most often diagnosed in postmenopausal women, but women at any age with unopposed estrogen from any source are at an increased risk for developing endometrial hyperplasia. Hyperplasia with cytologic atypia represents the greatest risk fo...

OBJECTIVE To assess the role of endometrial thickness on vaginal ultrasound assessment and menstrual history in predicting endometrial hyperplasia in women with polycystic ovary syndrome (PCOS) who presented with infertility due to anovulation. METHODS This was a prospective study in a university referral-based fertility and endocrine clinic. Fifty-six women with PCOS presenting with infertil...

background: endometrial secretion analysis is a non-invasive and promising method in evaluation of endometrial receptivity. objective: the aim of the present study was to assess the relationship between the success rate of ivf procedures and some endometrial secretion cytokines, including interleukin-1β (il-1β), tumor necrosis factor (tnf-α), interferon gamma-induced protein 10 (ip-10), and mon...

background: stem cell factor (scf) is a transcriptional factor which plays crucial roles in normal proliferation, differentiation and survival in a range of stem cells. objective: the aim of the present study was to examine the proliferation effect of different concentrations of scf on expansion of human endometrial cd146+ cells. materials and methods: in this experimental study, total populati...

Background In patients with abnormal uterine bleeding, transvaginal ultrasound (TVS) is the first-line diagnostic approach to exclude endometrial pathology. If a thickened endometrium suggests endometrial pathology, sonohysterography, office hysteroscopy or dilatation and curettage are the second-line tests preferred, depending on availability and on the suspected pathology, to exclude malignan...

Background: To investigate whether endometrial volume on the day of HCG (human chorionic gonadotropin) administration is a predictor of ART (assisted reproductive outcome) outcome Materials and Methods: Two hundred and seven patients in ART cycle were included in this prospective study; In order to evaluate endometrial volume and its relationship to ART outcome. Endometrial volume obtained from...
