  • Pyogenic granuloma is one of the common benign vascular tumors of infants and children and it can also occur in adults. There are 25 reports of patients with pyogenic granuloma in the Korean medical literature. In three reports, giant pyogenic granuloma developed over 2 cm in size ($1.3{\times}0.7cm$, $1.2{\times}0.8cm$ and $1.1{\times}0.7cm$, respectively). There have been no reports in the Korean medical literature of pyogenic granuloma over 2 cm in size. Herein, we report on a giant pyogenic granuloma on the palm of a 72-year old female. The lesion was of an unusually large size of $2.8{\times}2.5{\times}1.3cm$ and we excised it by performing electrosurgery.

  • Gingivectomy has been utilized as a therapeutic method to remove diseased periodontal pocket wall in order to aid in root planing. Although chemical agents and electrosurgery has been used in addition to the conventional method of using surgical blades, difficulties in controling the depth of chemical penetration and effectively regenerating the gingival tissue as well as the slow wound healing has been pointed out as shortcomings of these methods. This study was designed to assess the effect of Aloe vera on wound healing of gingivectomy sites created by $CO_2$ laser on palatal gingiva of maxillary molar region of white rats. Those sites treated by surgical blades were designated as control, by $CO_2$ laser as Experimental group I, by surgical blades in addition to topical application of Aloe vera as Experimental group II, and by $CO_2$ laser and Aloe vera application as Experimental group III. Animals were sacrificed at 2 days, 3 days, 1 week, 2 weeks and 3 weeks postoperatively, and the specimens were histologically analyzed. The results were as follows : 1. Resorption of blood clots were observed in the control at 3rd day, followed by the rest of the experimental groups at 1 week postoperatively. 2. Persistent inflammation was observed up to 1 week in the control and Experimental group II and III, and until the 2nd week in Experimental group I. 3. Granulation tissue was observed up to 1 week in the control, and 2 weeks in the rest of the groups. 4. Epithelization started on the 2nd day. The control showed the most rapid epithelization, and the process was completed by the 2nd week in all groups. 5. Experimental group II and III, which were treated with Aloe vera, showed similar healing patterns to the control and Experimental group I.

  • Conventional surgical therapy for oral soft tissue includes the use of scalpel, diathermy, cryotherapy and electrosurgery. But, these therapies have some surgical problems. Nowadays, laser surgery can be considered as the another option for conventional surgical therapy. Compared to conventional surgical therapies, advantages of laser therapy include maintenance of sterile conditions, promotion of wound healing, reduction of bleeding, less instruments, post operative pain reduction, less scar, saving cost by using fewer materials, staff and time. Carbon dioxide ($CO_2$) laser uses gaseous medium, and has long wavelength about 10,600nm. The first advantage of $CO_2$ laser for surgical treatment of oral soft tissue is hemostasis and visibility improvement by making relatively dry field. These case reports are about cases of minor surgery of oral soft tissue using $CO_2$ laser, and emphasize advantages of laser compared to conventional surgical therapies.

  • Carbondioxide($CO_2$) laser is one of the most widely employed lasers in oral soft tissue surgery because of its excellent affinity for water based soft tissues. It has some inherent advantages such as hemostasis, less postoperative swelling, reduction of bacterial population at surgical site, less need for suturing, less scarring, and less postoperative pain compared to conventional surgical therapies including the use of scalpel, diathermy, cryotherapy and electrosurgery. A 30-years-old male was presented with gingival swelling. Clinical examination revealed a well?defined pedunculated fibrotic mass on the buccal gingiva near right maxillary 1st molar. In radiographic examination, no remarkable abnormality was seen. Excisional biopsy was performed with $CO_2$ laser (continuous wave mode, 4.0W). Histological diagnosis was "Irritation fibroma". $CO_2$ laser has advantages those are suitable for surgical treatment of intraoral lesion. If appropriate training and experience are provided, the dentist would be able to manage intraoral lesions more efficiently and successfully with the use of the $CO_2$ laser.
