RETRACTED ARTICLE: A fluorescent Zn(II)-containing coordination polymer for antibiotic sensing and treatment activity on periodontal tissue inflammation after orthodontics by inhibiting the growth of Porphyromonas gingivalis

Antimicrobial Activity of Zinc against Periodontal Pathogens: A Systematic Review of In Vitro Studies

“…Finally, 15 articles were chosen based on inclusion and exclusion criteria. All the scientific publications examined the in vitro antibacterial activity of zinc-ion-containing substances on at least one bacterium associated with periodontal diseases [4,[8][9][10][11][12][13][14][15][16][17][18][19][20][21], while four publications investigated the toxicity of Zn compounds on gingival fibroblasts [4,8,10,12]. The activity of zinc against bacteria was studied during 24 and 48 h periods, with the longest test duration being three days [20].…”

“…Antibacterial activity was tested using different substances in various concentrations. ZnO nanoparticles were the primary test substance in four publications [8,10,16,18], while 11 publications also examined an additional zinc-containing compound [4,9,[11][12][13][14][15]17,[19][20][21]. In one publication, free ZnO was studied in combination with an additional substance, polycaprolactone [4].…”

“…Zinc (Zn) is an antimicrobial substance that has been used in medicine for several decades [8]. Research has demonstrated the antimicrobial efficacy of zinc oxide nanoparticles [10,11]. The application of zinc in periodontology has not been thoroughly investigated yet.…”

“…Scientists are still studying the effects of zinc on oral bacteria and inflammatory periodontal tissues. The results should help answer whether the topical application of zinc (as part of a medication system) can accelerate or enhance the healing of periodontal tissues as this substance can be released directly to the target location at constant concentrations [4,[8][9][10][11][12][13][14][15][16][17][18][19][20][21]. Topical administration of zinc medications into periodontal tissues could provide prolonged action and effectiveness [9].…”

Highly pH-stable lanthanide MOFs: a tunable luminescence and ratiometric luminescent probe for sulfamethazine

“…Heretofore, some luminescent MOF sensors for SMZ have been constructed, all of which are single-emission luminescent probes. [33][34][35][36][37][38] However, such probes may be disturbed by equip-ment fluctuation, environment, and material concentration inhomogeneity, which makes it difficult to accurately distinguish the variation of intensity. A dual-emission ratiometric luminescent probe not only has inherent signal intensity calibration that can effectively overcome interference, but also distinguishes color changes more easily than a single-emission luminescent probe in practical analytical applications.…”
