Assessment Of Human Alveolar Bone Density By Using Volumetric Ct Machine, Prasit Aranyarachkul
Loma Linda University Electronic Theses, Dissertations & Projects
This study evaluated bone density in designated implants sites using cone-beam computed tomography (CBCT) and compared the measurements to those of quantitative computed tomography (QCT) and subjective bone density evaluation. Sixty-two designated implant sites in 9 human cadavers jaws were used. Indicator rods, 2 mm in diameter, were placed in all sites. CT images representing 1 mm bucco-lingual slices immediately mesial and distal to the rods were selected for density evaluations. Bone density in Hounsfield units (HU) was assessed in a standardized implant area superimposed on the images, and also subjectively evaluated by 2 independent examiners using the Lekholm & …

Il-10 And Alveolar Bone Loss, Abdulaziz Saud Al-Rasheed
Loma Linda University Electronic Theses, Dissertations & Projects
Interleukin-10 (IL-10) is a cytokine with anti-inflammatory activities. IL-10 knockout (KO) mice exhibit severe intestinal inflammation in the presence of normal gut flora. We hypothesized that IL-10 KO mice would also be susceptible to inflammatory periodontal disease resulting in alveolar bone loss (ABL). The purpose of this study was to compare naturally occurring ABL in IL-10 KO and wild type (WT) mice. Twelve IL-10 KO and 12 WT mice, age-(7 months) and sex-(male) matched, were used. Half of the mice were on 129/SvEv and half on C57BL/6J background. Animal heads were defleshed and treated to remove all organic material. ABL …
Pain Experienced By Patients During Periodontal Recall Treatment, Thu-Diem Chung
Pain Experienced By Patients During Periodontal Recall Treatment, Thu-Diem Chung
Loma Linda University Electronic Theses, Dissertations & Projects
The aims of this study were to determine; 1) the degree of pain experienced by patients during probing and debridement; 2) if the treating hygienists could estimate the degree of pain experienced by the patients; and 3) if the patients' pain responses could be predicted by factors such as the patients' age, gender, number of residual periodontal lesions, and the patients' answers to a questionnaire on dental anxiety.
Prior to the maintenance procedures, 2 groups of 20 adult patients to be treated by 2 hygienists completed an anxiety questionnaire. Subsequently, measurements of probing depths were performed, followed by pain ratings …
