Background
Periodontitis is a chronic infectious disease involving four periodontal supporting tissues (gingiva, periodontal ligament, alveolar bone and cementum), often causing inflammatory destruction of the periodontal supporting tissues. Periodontitis is mainly classified into chronic periodontitis, aggressive periodontitis, periodontitis reflecting systemic diseases, and necrotizing periodontal disease. When the oral periodontitis is treated, a treatment medicament is generally injected and molded in an inflammation area, and the medicament directly acts on the inflammation area, so that the elimination of inflammation is accelerated. Needle syringes are used in the injection of drugs. Syringes are a common medical device. As early as the 15 th century, kathler, italian, proposed the principle of the syringe. Gas or liquid is primarily drawn or injected with a needle.
