The study investigated whether dietary flavonoid intake and dietary patterns were associated with bone mineral density (BMD) and bone turnover in postmenopausal Scottish women. The subjects were recruited in 1990-3, and the majority of them returned 6.3 ± 0.6 y later (mean age (SD) at baseline 54.7 (2.2) y). At the both visits they had bone density scans of the lumbar spine (LS) and hip (FN) and at the second visit they provided urine samples for analysis of bone resorption markers. Flavonoid intakes were calculated using food frequency questionnaires, “validated” for flavonoid intakes using 4-day food diaries. (R=0.76, p≤0.001 for energy adjusted total flavonoids). FN BMD was associated with flavonoid intakes at baseline and follow up (p=0.012, p=0.001 respectively after adjusting for confounders) and LS BMD at follow up only (p=0.038). Dietary flavanones had a negative correlation with bone resorption markers; catechins and procyanidins were associated with annual change in FN and LS BMD. Principal components analysis was used to identify five important patterns in the diets. The “healthy” diet, rich in fruit and vegetables, was negatively associated with bone resorption markers and the nutrient diets were both negatively associated with FN and LS BMD. Partial least squares analysis identified that tinned fruit and root vegetables were associated with greater bone resorption, and berries, tomatoes and juice with decreasing bone resorption. Tomato intakes were the most important when predicting bone resorption marker excretion. Tomatoes, salad, berries, and green vegetables were associated with increased BMD. Berries, applies, root vegetables and salad were the most important fruit and vegetables for predicting BMD. Results from this work confirm that fruit and vegetables are important in bone health.

Background: The width of the facial alveolar bone wall is crucial for long term successful esthetic outcomes of implants immediately placed into extraction sockets. A threshold of 2 mm is recommended to minimize buccal vertical bone resorption. Aim: To assess the width of the facial alveolar bone wall using cone-beam computed tomography images (CBCT). Methods: Retrospective CBCT images were acquired from a representative sample of Asians using the i-CAT® classic system with a 0.4 mm voxel size. At random, 200 CBCT images were selected according to predefined criteria. The DICOM file was imported into the i-Cat Vision® software. In the panoramic screen, the middle of each tooth was selected and, in the sagittal window, the middle cross section was selected for performing the measurements using a computer. The vertical distance from the alveolar crest (BC) - CEJ was measured. The width of the facial alveolar bone wall was measured at three locations: 1, 3, and 5 mm apical to BC. Descriptive statistics, frequency analyses, and multi-level comparisons were performed. Results: The sample consisted of 74 males and 126 females (mean age of 37.2 years; range 17-82 years). A total of 3618 teeth were assessed. There was no significant difference between the values of right and left sides, or between genders. However, statistically significant differences were observed between age groups at all levels. The distance from CEJ-BC varied from 0.4 to 4mm, with an overall tendency to increase with age. The mean width of the facial alveolar bone wall at anterior teeth was 0.9 mm and increased towards posterior regions. Rarely, a width of 2 mm was yielded (0.6-1.8 % for anterior teeth, 0.7- 30.8 % for posterior teeth). At a 5mm distance from BC, minimal widths of facial alveolar bone were identified for the anterior teeth. The frequency of dehiscence ranged from 9.9- 51.6 % for anterior and 3.1- 53.6 % for posterior teeth, respectively. Conclusion and clinical implications: A thin facial alveolar bone wall was usually present in both jaws. Hence, for most patients, adjunctive bone augmentation may be needed when installing implants in areas of esthetic concern. / published_or_final_version / Dental Surgery / Master / Master of Dental Surgery
