2% minocycline hydrochloride controlled-delivery system (MHS)
The test product is a highly viscous gel for local subgingival placement composing of an ointment containing micro-capsule type particles for sustained release and the active ingredient 2% minocycline gel (10mg in each syringe of 0.5g) (Periocline, SUNSTAR, Osaka, Japan). The other ingredients include magnesium chloride, hydroxyl-ethylcellulose, aminoalkylmethacrylaye copolymer, triacetin and concentrated glycerine, giving the preparation a sustained-released property. It will be applied to experimental teeth and the adjacent teeth by gently inserting the tip of a specially designed applicator until the paste flows over the gingival margin.
