AI Article Synopsis
- The study aims to assess palatal bone density to improve the choice of implant anchorage sites.
- CT scans were conducted on 30 participants (15 males and 15 females) to measure bone density at specific points along the midpalatal suture.
- Findings reveal that bone density varies across the palate, with the densest area located near the midline, and suggest that mini-implants can be successfully placed in most regions of the palate if positioned properly.
Article Abstract
Objectives: To evaluate palatal bone density to allow for better selection of palatal implant anchorage sites.
Materials And Methods: Computed tomographic (CT) images were obtained from 15 males and 15 females (mean age, 27 years; range, 23-35 years). Bone density was measured in Hounsfield units (HU) at 80 coordinates at regular mediolateral and anteroposterior intervals along the midpalatal suture.
Results: Bone densities ranged from 805 to 1247 HU. A significant difference between male and female groups was noted, although no difference was found between left and right sides of individual palates. Palatal bone densities showed a tendency to decrease laterally and posteriorly. The midpalatal area within 3 mm of the midsagittal suture had the densest bone in the entire palate.
Conclusion: Results suggest that mini-implants for orthodontic anchorage may be effectively placed in most areas with bone density equivalent to the palatal area if they are placed from 3 mm posterior to the incisive foramen and 1 to 5 mm to the paramedian side.

Unlabelled: Dietary quality may be a factor in the progression of non-communicable, chronic diseases. This analysis of NHANES data demonstrates association between consumption of UPF and prevalence of osteoporosis and osteopenia in adults 50 years and older. UPF intake is an important consideration when recommending dietary patterns for optimum bone health PURPOSE: Declining bone mineral density in older adults can result in osteoporosis, leading to decreased physical function, quality of life, and increased risk of mortality.

Background/purpose: -2,3,5,4'-tetrahydroxystilbene-2-O-β-D-glucoside (THSG) is a bioactive component in the Chinese herb Polygonum multiflorum, recognized for its anti-inflammatory and lipid-lowering properties. Human dental pulp stem cells (hDPSCs) have excellent capabilities in tooth regeneration, wound healing, and neural repair. The exosomes (Exo) released by hDPSCs contain bioactive molecules that influence cell proliferation, differentiation, and immune responses.

Background/purpose: Inferior alveolar nerve (IAN) injury is the most serious complication associated with dental implant surgery, posing difficulties in treatment and potential for permanent disabilities. This study aimed to identify patient-related risk factors for IAN injury during implant placement and to investigate sensory disturbances depending on whether the implant was removed.
Materials And Methods: Twenty-eight patients with implant-related IAN injury were included.

Background/purpose: Progesterone (PG) is sex steroid hormone that commonly used to control menopausal symptoms, but its exact role in periodontitis remains unclear. This study aimed to investigate the effects of PG on periodontitis in perimenopausal women and in an experimental rat model.
Materials And Methods: Total 412 perimenopausal women with periodontitis and a history of PG deficiency-induced uterine dysfunctional bleeding were enrolled, among which 209 women had been treated with PG.
