The largest and longest bone in the upper limb is the humerus. The nutrient foramen is an aperture in the bone's shaft that permits blood vessels to get to the bone's medullary cavity for nutrient and growth. The long bones' nutrient foramina have been the subject of numerous published research. Since the literature has not yet established a palpable landmark for the nutrient foramina, the purpose of this study was to characterize the nutrient foramen in dry adult humeri in terms of their numbers and location.
Methods: The study comprised all the humerii (not necessarily paired and those of unknown age and sex) from the university of the Aam Admi Party's medical colleges. The length of the humerus, the number of nutrient foramen, the size of the nutrient foramen, the location of the nutrient foramen in regard to the surfaces and the zones, and the distance of the nutrient foramen from the midpoint of the humerus were all observed. All the data were recorded, and the percentage, mean, range, and standard deviation were computed as part of the statistical analysis.
Results: In our study we examined 147 humeri. Among 147 examined humeri there were 82 right humerus and 65 left humeri. The number of single nutrient foramen was most commonly recorded among examined humerus (78.91%). The examination of humerus for location of nutrient foramen based on surface showed that more than four fifth of nutrient foramen were located on anteromedial surface (83.67%). The mean total length of humerus examined was 269.75±22.53 mm and the mean distance from of nutrient foramen from proximal end of humerus was 151.93±17.57 and calculated foraminal Index (FI) was 55.36%.
Conclusion: When performing various surgical procedures on the humerus, such as treating fractures, bone repair, bone grafting, micro-surgical bone transplantation, in numerous fractures, and during extensive periosteal stripping, orthopaedic surgeons must have a thorough understanding of the anatomy of the number, location, and direction of the nutrient foramina of the humerus in order to minimise damage to the nutrient artery of the humerus.

BIOMATERIALS : A boon to Periodontal and Peri-Implant Regeneration

Rohini Parui, Dr. Dhirendra Kumar Singh

European Journal of Molecular & Clinical Medicine, 2022, Volume 9, Issue 7, Pages 5806-5827

Different levels of periodontal disorders erode the periodontal attachment. In addition to stopping these diseases, we must concentrate on regenerating and replacing the tissues that have been lost. On the other hand, the integration with the soft tissues is crucial to the success of dental implants, which are regarded as a blessing in the history of contemporary dentistry. Regardless of the chosen material and design, a successful outcome can only be obtained with the healing of the soft tissue layer positioned between the implant and the bone. Numerous biomaterials and biological mediators have been developed for years in an effort to restore the injured tissues completely using less invasive methods. Several of them are cited in various articles and evaluations from different sources as being summarized here

Study protocol for comparative evaluation between open flap debridement, osseous resective surgery and autogenous bone graft in treatment of hemiseptal periodontal defect - A clinical and radiographic study

Dr. Vaibhav Tiwari; Dr. Prasad V Dhadse

European Journal of Molecular & Clinical Medicine, 2020, Volume 7, Issue 2, Pages 2017-2026

Abstract: Background: Osseous resection is established treatment protocol for periodontal
hemiseptal defects, however this forces clinician to settle for less than optimal results and
leads to undesirable outcomes like unpleasant esthetics, denitinal hypersensitivity, root caries
etc. the present treatment protocol is designed to asses defect resolution by autogenous bone
pieces in treatment of periodontal hemiseptal defects. Objectives: To evaluate the soft and
hard tissue response using clinical parameters like probing pocket depth(PPD), clinical
attachment level(CAL) and radiographic bone fill in treatment of hemiseptal periodontal
defects to Open flap debridement, Osseous resective surgery autogenous bone graft. Methods:
the study sample will be randomly divided in to 3 groups of 12 hemiseptal defects each. Group
1 to be treated by resective osseous surgery, Group II treated by open flap debridement and
Group III treated by Autogenous bone graft. Clinical parameters include gingival index,
probing pocket depth and clinical attachment level along with radiographic assessment with
radivisograph (RVG) and cone beam computed tomography (CBCT). All parameters will be
evaluated at baseline, 3, 6 and 9 months interval. The Independent-Samples t Test will be done
to compare means for two groups.” The Paired-Samples t test to compare means of two
variables for a single group. Difference will be considered significant when p value <0.05.
Expected results: Proposed approach is expected to show improvement in probing pocket
depth, clinical attachment level, and gingival index. It is also expected to gain defect fill
reduction or resolution of hemiseptal defect. Conclusion : By attempting to treat periodontal
hemiseptal defects with regenerative method this study is attempting to avoid all undesired
effect associated with osseous resection and provide evidence of regeneration in such defects,
this can lead to paradigm shift in treatment approach of periodontal hemiseptal defects.Q
