The impact of the Covid-19 has made the elderly's access to dental and oral health even more limited. Oral hygiene in the elderly living in nursing homes is often ignored so it falls into the poor category. The high prevalence of caries and other dental problems makes the elderly need more dental treatment. Poor oral health can lead into systemic or local infections that will affect general health, especially in the elderly who have impaired physiologic or pathologic function. Increased knowledge will improve their oral hygiene. Therefore, to increase members' knowledge and awareness to oral health, FKG Trisakti held an education to maintain their oral health and dentures. Pre and post tests are given to the participants to determine the success of the education. T test result showed increase in knowledge from participants before and after giving the material. Further training can be given to caregivers as they were there to help the elderly maintain their oral care.
Background: Periapical abscess caused by tooth necrosis which are not treated. Enterococcus faecalis and Staphylococcus aureus area found in periapical abscess. Cefadroxil is one of antibiotics that choices to treat this infection. Several studies proved that C. sinensis leaves extract contains metabolite compounds such as catechins that can inhibit bacterial growth. To determine the antibacterial effect of C. sinensis leaves extract and cefadroxil combination against E. faecalis dan S. aureus growth. Methods: Laboratory experimental research with diffusion method. The research design is post test only control group design. Treatment was carried out with C. sinensis leaves extract 125 mg/mL, combination of C. sinensis leaves extract 15,625 mg/mL, 31,25 mg/mL, 62,5 mg/mL and 125 mg/mL with cefadroxil 8 μg/mL , cefadroxil 16 μg/mL as a positive control, and NaOH 0.1 N as a negative control. Results: There was none of inhibition zone in C. sinensis leaves extract 125 mg/mL and NaOH 0.1 N. The combination of C. sinensis leaves extract 15,625 mg/mL, 31,25 mg/mL, 62,5 mg/mL and 125 mg/mL and cefadroxil 8 µg/mL had an antibacterial effect. Based on Post-hoc Tukey’s HSD test, there was no significant difference between the combination and positive control. Conclusion: C. sinensis leaves extract and cefadroxil has potentially antibacterial effect on E. faecalis and S. aureus.
Tooth pain is the most common form of orofacial pain. Tooth sensory system is very sensitive to detect noxious stimulus. Most of sensory stimulus, which come from pulp afferent fibres will cause pain sensation. Action potential transmits the stimulus from periphery to the central. Sodium channels have an important role to generate and propagate the action potential. One of its isoforms, Na v 1.8, has only found in sensory nerve, especially in nociceptive neuron that deliver pain stimulus. In myelinated neuron such as A-δ fibres, sodium channels located in high density on the node of Ranvier. The density of sodium channel Na v 1.8 has a strong relation with tooth sensitivity. We implement method to detect nodes of Ranvier and detect Na v 1.8 as our region of interest. In this paper, threshold and local enhancement is used for nodes of Ranvier detection and improvement of Euclidean path for sodium channels Na v 1.8 detection.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
