The most significant source of dental evidence is oral autopsy applications, which consist of an examination and evidence collection from the oral cavity of a deceased individual. Oral autopsies show variations depending on the age of the person due to rigor mortis. The oral autopsy of a child may require an easier operation than adults, and thus, the procedures are usually simpler for fetus or infant cases. The aim of this study is to propose the theoretical and experimental aspects of an oral autopsy protocol for a special age group of fetus or infant cases, which is a method for extracting tooth germs in their developmental stages for identification purposes and entitled by the authors’ names as the “Aka-Canturk Oral Autopsy Method”.展开更多

Methods： A 54-year-old patient with upper lobe of the left lungsquamous cell carcinoma was studied, who suffered from severe cancer pain with the initial numeric rating scale （NRS）7 point when admitted. Exterior-use formula was applied to pain spot to relieve the pain. Mixed methods approachcomprising NRS, Short-form of McGill Pain Questionnaire, quality of life scale, times of breakout pain, records ofadverse reactions and semi-structured interviews were utilized to evaluate the effect. Results： With the combination useof the formula and analgesic drugs, the patient’s NRS score dropped from 7 to 3 point. Quality of life scale scoreimproved from 33 to 42 point. Times of breakout pain reduced from twice to none. The amount of oxycodone decreasedfrom 30 mg Bid to 10 mg Bid. No adverse effect appeared. The patient’s felt more energetic with good sleep and appetite.Conclusion： This formula is effective and safe for pain relief when combined with analgesic drugs, and may be a goodoption in dealing with local cancer pain. Future randomized, controlled studies are needed to better evaluate the efficacy.展开更多
