citric acid and tetracycline hcl are the most common clinical root demineralization agents used in periodontal practice. in this comparative in vitro study the effects of nd: yag laser radiation on root surface was compared to that of citric acid and tetracycline hcl using sem. a total of twenty-one freshly extracted periodontally diseased single rooted premolar teeth were root planned in vitro...

Metronidazole, tetracycline HCl and famotidine are commonly used for the treatment of Helicobacter pylori-associated peptic ulcer. In this paper, stabilities of these drugs and their combinations in solid and liquid states were studied as part of preformulation in the development of a combination drug delivery system. Solubility studies of metronidazole and tetracycline HCl were investigated, w...

Ivermectin, chloramphenicol, ampicillin and tetracycline HCl are common drugs in human and veterinary practice. The purpose of this study is to investigate the possible binding interactions between ivermectin and the antibiotics chloramphenicol, ampicillin and tetracycline HCl. Isothermal titration calorimetry was used to determine the binding interactions between ivermectin and these antibioti...

Tetracycline class agents vary widely in their activity against emerging important antimicrobial-resistant pathogens such as methicillin-resistant Staphylococcus aureus (MRSA) and Acinetobacter spp. Also, published susceptibility breakpoints are discordant between the Clinical and Laboratory Standards Institute (CLSI), the European Committee on Antimicrobial Susceptibility Testing (EUCAST), and...

Preparation of bentonite clay–coconut husk composite (BECH) via microwave-assisted carbonization, the activation BECH with HCl (BECH-H) and KOH (BECH-K) adsorption ciprofloxacin, tetracycline, bisphenol A from aqueous solutions.

BACKGROUND The present study is designed to evaluate the clinical effects of pulsated subgingival irrigation with tetracycline and spiramycin. MATERIALS AND METHODS Ten patient diagnosed chronic periodontitis were included in the present study. Each patient is assigned to be irrigated with saline (placebo) (Group A), tetracycline HCl at 0.5% concentration (Group B), and 0.5% spiramycin (Group...

G.S. 2989 Hcl (Pfizer) is a new tetracycline derivative without any generic name. In a cinico-cytological study by Nema, Nath, Bal, and Shukla (1964) on 48 trachomatous cases treated by G.S. 2989 Hcl (025 per cent. in oil) the antibiotic was found quite effective against trachoma and associated bacterial conjunctivitis. It was observed that the drug could produce 66-7 per cent. cure of trachoma...

OBJECTIVE The present in vitro study has been designed to establish and compare the effects of citric acid, EDTA, and tetracycline HCl on human periodontally diseased roots on the structure, attachment, and orientation of V79 (primary Chinese hamster lung fibroblasts) cells and human periodontal ligament fibroblasts (HPDL). MATERIALS AND METHODS Commercially available V79 cells and HPDL deriv...
