Pyogenic granuloma (PG) is a kind of inflammatory hyperplasia seen in the oral cavity. This term is a misnomer because the lesion is unrelated to infection. In reality it arises in response to various stimuli such as low-grade local irritation, traumatic injury or hormonal factors. It predominantly occurs in the second decade of life in young females possibly because of the vascular effects of female hormones. It is also called as pregnancy tumor because of its high frequency of occurrence during the early part of pregnancy. Even though, this lesion is non-neoplastic and treatment procedure is simple, it should be diagnosed correctly before proceeding with the treatment. The most common site for PGs is gingiva (75%) and rarely in the palate. In this case report, we are going to present very rare occurrence of pregnancy tumor in the hard palate.

Chitosan is a biopolymer with numerous biological properties such as antibacterial, anti-inflammatory, and wound healing. Chitosan also stimulates cell proliferation and osteogenesis and thus used as a scaffold material in tissue engineering. The physical proprieties of chitosan such as biocompatibility and biodegradability give promising results in periodontal therapies. This review gives an updated explanation of the applications of chitosan in dentistry and periodontics. Furthermore, the review demonstrates the actions of chitosan in detail and its role in the regeneration of periodontal structures.
