AI Article Synopsis
- The study aimed to analyze the dimensions of the obturator foramen and pubic arch in female pelvices to identify variability.
- Ninety-six female pelvis samples were examined, measuring several anatomical features, with linear regression used for analysis.
- Results showed significant differences in bone structure, especially noting that European American women had larger measurements in certain areas compared to African American women, while height was a contributing factor to obturator foramen size.
Article Abstract
Objective: The purpose of this study was to determine dimensions of the obturator foramen and pubic arch of the female pelvis and to assess for variability.
Study Design: Ninety-six female pelvises were selected from the Cleveland Natural History Museum. The obturator foramen area, pubic arch angle, pubic ramus, pubic symphysis, and anterior urogenital triangle area were measured. Linear regression was used to evaluate independent associations.
Results: There was considerable variability of the bony architecture. The mean obturator foramen area was 12.2 +/- 2.1 cm(2) (range, 7.38-18.22 cm(2)). After controlling for height, the pubic ramus width, pubic symphysis length, and interobturator foramina distance were significantly greater in European American women compared with African American women. Obturator foramen area increased with increasing height (P = .0008) but was not associated with race.
Conclusion: There is considerable variability in the bony architecture of the obturator foramen and pubic arch of the female pelvis. Race and height may account for some of these variabilities.

Background/purpose: The impact of thermal behavior on the clinical performance of gutta-percha points (GP) is unclear. This study aimed to investigate the thermal behavior of three different types of GP and their temperature changes (TC) in a simulated clinical environment.
Materials And Methods: The GP tested were Conform Fit® Gutta-Percha Points (CF), Autofit™ Feathered Tip Gutta Percha (AF), and Gutta Percha Root Canal Points (GC).

Objectives: The purpose of this study is to determine what demographic and anatomical variables affect successful placement of a superior medullary ramus screw, and how they affect the maximal diameter of that screw.
Methods: Design: Prognostic Level IV SETTING: Level I Trauma Center Patients/Participants: Two hundred consecutive patients underwent computed tomography (CT) of the pelvis. We included those patients aged 18 and older without osseous injury or abnormalities precluding measurement.

The greater sciatic, lesser sciatic and obturator foramina are openings in the pelvis through which pelvic lesions can herniate, leading to the formation of rare dumbbell tumours. We present the case of a man in his late 60s, who presented with obstructed defecation. A per rectal examination revealed a palpable right sided rectal mass.

Introduction: This study aimed to assess the effect of cavity designs on instrumentation, obturation and fracture resistance for mandibular first premolars with Vertucci V canal.
Methods: Mandibular first premolars with Vertucci V canal were scanned with microcomputed tomography. A total of 20 teeth with moderately curved canal were prepared with conservative endodontic cavity (CEC/M) or traditional endodontic cavity (TEC/M), and 30 with severely curved canal were prepared with CEC (CEC/S), modified CEC (MCEC/S) or TEC (TEC/S).

Purpose: This study was aimed to compare the difference between iRoot SP and AH Plus on root canal sealing ability for teeth extracted due to severe periodontitis and explore whether the dentin tubule pathway plays an important role in the development of endodontic-periodontic lesions(EPL), in order to provide a theoretical basis for selection of proper time for root canal therapy and suitable root canal sealants in patients with EPL.
Methods: Fifty single-root anterior teeth extracted due to severe periodontitis were selected. The roots were completely debrided to remove the calculus, dental plaque and cementum.
