Materials and Methods: Sixty postmenopausal female patients aged 51-68 years were included in the study to assess the relationship between tooth loss and the level of blood pressure. The information including sociodemographics, last menstruation period, hypertension history, and the duration of having tooth loss was recorded. Blood pressure was measured using sphygmomanometer and the number of tooth loss was determined.
Results: The results showed a more significant tooth loss in hypertension (median: 23 + 4; interquartile range [IQR]: 6) compared to the normotension postmenopausal women (median: 18 + 6; IQR: 12; P < 0.05). Furthermore, obese patients had more tooth loss (median: 23 + 5; IQR: 8) than the overweight patients (median: 19 + 8; IQR: 8).
Conclusion: Tooth loss is associated with the increase of hypertension in postmenopausal women which may have a role in the development of vascular diseases.
MATERIALS AND METHODS: This retrospective study examined the data of 248 patients who have attended dental clinic at Faculty of Dentistry IIUM and suffering from different types of orofacial pain. The data were collected from January 2010 to November 2018. The etiologies of pain were classified according to International Classification of Orofacial Pain, 1st edition (2020).
STATISTICAL ANALYSIS: The association of age and gender with orofacial pain was evaluated by using the Chi-square test, and the significance level was set to 0.05.
RESULTS: Collected data showed that orofacial pain has different etiologies among the patients attending the dental clinic at Faculty of Dentistry IIUM. Moreover, a statistically significant relation was observed between orofacial pain toward gender and different age group.
CONCLUSION: The findings proposed that the orofacial pain has a variety of etiological factors with the highest percentage of orofacial pain attributed to disorders of dentoalveolar and anatomically related structures among patients attending dental clinic at Faculty of Dentistry IIUM.
MATERIALS AND METHODS: Twenty-three MOS patients were draped with eyes covered, while another 23 MOS patients were draped with eyes uncovered. Stress parameters such as systolic and diastolic blood pressures (DBP), mean arterial pressure (MAP), heart rate, random blood glucose, and Spielberger State-Trait Anxiety Inventory (STAI)-6 questionnaire score were recorded accordingly in the different intervals; then statistically analyzed later.
RESULTS: Closed eyes patients had significantly lower mean DBP and MAP (73.91 ± 6.80/88.94 ± 6.88 mm Hg) as compared with open eyes patients intraoperatively. Though significant only in the postoperative phase, the closed eyes group had a relatively lower mean heart pulse rate than the open eyes group in all surgical intervals. Postoperatively, closed eyes patients had lower mean blood glucose level as compared with open eyes group. STAI mean score revealed a higher psychological stress for closed eyes patients versus open eyes patients.
CONCLUSION: Closed eyes patients displayed lower quantifiable physiological stress level as compared with patients undergoing MOS draped with eyes uncovered. However, in qualitative psychological context, closed eyes draped MOS patients responded poorly as compared with opened eyes draped patients under similar surgical stress.
MATERIAL AND METHODS: Leaves of G. umbrosus were cleaned, air dried, ground, and soaked for 24 hours with methanol and hexane repeatedly three times, respectively. Pooled extracts of each solvent were then dried with a rotary evaporator. Anticancer potential of G. umbrosus extracts was evaluated on two OSCC cell lines (SCC-15 and HSC-3) and a normal HGF cell line incubated for 24, 48, and 72 hours by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The cytotoxicity of cisplatin was assessed as a positive control. Morphological changes of cells were observed under an inverted microscope.
RESULTS: MTT assay revealed that G. umbrosus methanol extract (GUME) displayed moderate anticancer activity on SCC-15, HSC-3, and HGF cell lines with IC50 values of 126.67, 90.5, and 87.33 µg/mL following 72 hours' incubation times, respectively. G. umbrosus hexane extract (GUHE) exerted moderate anticancer activity against SCC-15 and HSC-3 cell lines with IC50 values of 171 and 174 µg/mL, respectively, but weak cytotoxicity against the HGF cell line with IC50 value of 343.5 µg/mL. Cisplatin exerted a strong cytotoxic impact on both OSCC and HGF cell lines. Morphological observation revealed the characteristics of cells undergoing apoptosis.
CONCLUSION: The findings show that GUHE was more selective in inhibiting the proliferation of oral cancer cells than GUME by exerting moderate cytotoxicity on OSCC cell lines and weak cytotoxicity in HGF cells, while GUME exerted moderate cytotoxicity on both. These findings suggest a more targeted anticancer effect by GUHE as compared with cisplatin, which exerted nonselective cytotoxic activity. These findings provide a groundwork for the development of more targeted plant-based treatment for oral cancer.
