Background and Objectives : Tongue-tie, or partial ankyloglossia, is manifested by an abnormally short and thick lingual frenulum. Degree of tongue-tie varies from the mild to the rare, severe and its treatment of choice is frenulotomy. Theoretically tongue-tie can affect expression of alveolar sounds. The purpose of this study is to evaluate the degree of articulation problem and to evaluate the efficacy of frenulotomy itself on alveolar sounds in tongue-tie patients. Materials and Methods : Prospectively, the authors performed preoperative and postoperative speech evaluation using picture consonants test for tongue-tie patients. Percentage of consonants correct(PCC), mean value of each alveolar phoneme depends on articulation site were evaluated. for exclusion of other articulatory improving factors except of frenulotomy itself, postoperative picture consonants test was performed 1 month after surgery. Results : Preoperative speech evaluation was performed to 37(male 21, female 16) patients and postoperative speech evaluation was performed to 17(male 9, female 8) patients, the other 20 patients were follow-up loss. Low PCC was observed in tongue-tie patients and PCC of female was higher an at of male in 2-4 years old patients. Overall PCC was improved after frenulotomy. Preoperative mean value of liquids and fricatives was lower than the other alveolar phonemes(p＜0.05) and it was improved postoperatively(p＜0.05). Conclusion : Frenulotomy itself can improve the articulation of liquids and fricatives on short follow-up. Speech therapy would be needful for improvement of the other alveolar phonemes.

Objectives : The purpose of this study was to analyze the types of dental emergencies. This study was carried out for dental trauma patients visiting the emergency room in H hospital from 2005 to 2006. Methods : Subjects were 252 patients. Demographic characteristics consisted of age, gender, dentition, and dental related injury. Results : Male patients had 1.65 times higher tooth injury than female. Teenagers had higher prevalence of tooth injury. Main cause of dental injury was falling down. Young children accounted for 41.7% of the injuries. Late evening was the highest outbreak time of injury. The most commonly affected teeth were central incisor and lateral incisor. The damage of oral soft tissue was more common than the that of alveolar bone. Main area of primary tooth loss was gingiva(10.7%), tongue or soft palate(7.5%), and frenulum(6.0%). Subluxation(28.6%) and luxation(28.6%) were main cause for the primary teeth. Tooth fracture(50.0%) were the most common injury. Conclusions : Thus, to understand the incidence, causes and patterns of dental trauma is to help preserving natural teeth. The results of this study could provide the clinical guidelines on the treatment of dental emergency patients.
