Epidermoid cysts, dermoid cysts and teratoid cysts are cystic malformations lined with squamous epithelium. They present as soft nodular lesions with a sessile base. Their prevalence is 7% in head and neck patients and 1.6% within the oral cavity. The authors present a case series of 21 patients with dermoid and epidermoid cysts who underwent surgical removal. One year of follow-up was carried out without evidence of recurrence. The removal of these cysts is of great concern as it can cause serious social stigma, aesthetic and functional impairment, dysphagia and dysphonia. Key words:Epidermoid cyst, dermoid cyst, cystic malformations ABSTRACTArticle history:

Purpose:Conventional alveoloplasty procedure using manual instruments results in higher resorption of the residual alveolar ridge, which is unsuitable for denture construction. The purpose of this study was to evaluate the effect of piezosurgery-assisted alveoloplasty using minimally invasive technique compared to that of the conventional technique.Materials and Methods:This was a comparative in vivo study. The study sample consisted of 35 edentulous patients with bilateral bony spicules requiring alveoloplasty. The primary outcome variables assessed were time required for alveoloplasty, postoperative pain using visual analogue scale (VAS), and postoperative healing using Landry, Turnbull, and Howley healing index. The differences between the outcome variables were statistically analyzed using paired t-test.Results:The participants consisted of 35 patients (25 men and 10 women; age range: 38–83 years) diagnosed with bilateral bony spicules on the edentulous alveolar ridge. There was a statistically highly significant difference between both groups with respect to the outcome variables such as time required, VAS at 2nd day, and healing index at 7th day with higher mean of time required (in sec), higher mean of VAS, and lower healing index for conventional group as compared to piezo group (P < 0.05).Conclusion:Alveoloplasty done using piezosurgery not only reduces patient's postoperative discomfort but also maintains the alveolar bone integrity by not disturbing the soft-tissue and hard-tissue architecture, allowing faster healing of tissues, which makes the future prosthesis replacement easier
