Ankyloglossia, or tongue-tie, is a congenital condition which occurs as a result of fusion between the tongue and the floor of the mouth. Ankyloglossia often results in malocclusion with an anterior "open bite" deformity, early prognathism, swallowing problem, speech disorder, and periodontal problem. Generally lingual frenectomy is used for treatment of ankyloglossia, but incomplete operation and simple frenectomy may produce a scar contracture resulting in a more deformed ankyloglossia than was present initially. The Z-plasty is used for the correction of scar contractures and the replacement of missing tissue and this procedure is ideally suited for the treatment of an ankylosed frenum. Most authors advise postponement of any decision for surgical correction of tongue-tie until the age of 4 years, unless the child is having much difficulty with sucking or swallowing. We treated 4 patients with ankyloglossia using Z-plasty technique. As a result, we found out that it was effective for correction of movement limitation of tongue, prevention of relapse. Further, periodic check ups are needed for evaluation of relapse, improvement of speech, and other functions of the tongue.

전치부 공극의 치료법으로는 교정적인 폐쇄, 수술에 의한 방법, 보철에 의한 치료등의 방법이 있으며 이중 교정적인 폐쇄에 의한 치료법은 가장 보존적인 방법으로 많이 사용되고 있으나 그 치료이후의 보정에 많은 문제가 있었다. 저자등은 전치부 공극을 가진 3증례의 치료후 재발과정과 보정과정을 관찰한 결과 다음과 같이 요약할 수 있었다. 양 중절치가 서로 직접 연결되지 않는 보정장치의 사용은 영구보철물에 의한 경우에도 재발을 가져왔다. $\cdot$ 교정적으로 공극을 폐쇄한후, 순소대절제술, circumferential supracrestal fibrotomy 그리고 양 중절치가 서로 연결된 설측 부착 보정장치의 시행으로 좋은 유지 효과를 얻었다. 이상의 결과로 미루어 볼때 전치부 공극은 교정적 치료후, 순소대절제술, fibrotomy등을 시행한 후 반드시 양 중절치를 연결하는 고정성 보정 장치가 필요하다고 생각된다.

The mandibular buccal frenum is defined as a fold of mucous membrane at the posterior labial vestibule and attaches the lips and the cheeks to the alveolar mucosa, gingiva, and underlying periosteum. The buccal frenum becomes a problem when its attachment is too close to the marginal gingiva. It may then pull on healthy gingiva, encourage plaque formation and interfere with tooth brushing. Especially, heavy buccal frenum mucogingivally results in insufficent attached gingiva, inadequate vestibular depth and high frenum attachment and also difficulty in eruption of mandibular premolar. Frenotomy, frenectomy and mucogingival surgery are used in treating heavy buccal frenum. Frenotomy with autogenous free gingival graft has been used popularly because of its stable result. But, it is difficult in younger children because of inadequate donor site, difficulty in making recipient site and behavior management. Frenotomy with apically positioned flap is considered as more efficient way for a very young child with heavy buccal frenum. Additionally, modified deep sedation with $N_2O-O_2$ can be used as an adjunct for the effective treatment outcome. Decrease in muscle pull, adequate width of attached gingiva and increased vestibular depth can be expected from this treatment approach.

The mandibular buccal frenum is a fold of mucous membrane at the posterior labial vestibule, that attaches the lips and the cheeks to the alveolar mucosa, gingiva, and underlying periosteum. The buccal frenum becomes a problem if its attachment is too close to the marginal gingiva. It may then pull on healthy gingiva, encourge plaque formation and interfere with tooth brushing. Heavy buccal frenum mucogingivally results in insufficient attached gingiva, inadequate vestibular depth and high frenum attachment and also difficulty in eruption of mandibular second premolar. Frenectomy in various forms has been used for many years to remove the influence of the frenum. Unfortunately, the results are not always ideal and there is often postoperative relapse because of muscle pull. In this treatment, frenotomy was used in conjuction with autogenous free gingival graft with the object of removing the influence of the buccal frenum and creating an adequate and stable width of attached gingiva. We observed decrease in muscle pull, adequate width of attached gingiva and increased vestibular depth in addition to progressive eruption of second premolar. Periodic follow-up is needed for evaluation of relapse, grafting gingiva and also space regaining for second premolar.

Objective : There are close relationship between intraoral abnormal structure and speech-functional problem. Patients with cleft palate & ankyloglossia are typical examples. Patients with abnormal structure can be repaired toward normal structure by operation. Ankyloglossia may cause functional limitation - for example, speech disorder - even if adequate surgical treatment were done. And, each individuals have each speech disorders. The objective of this study is to evaluate the speechs of childrens with ankyloglossia, and to determine whether ankyloglossia is associated with articulation problem. We wanted to present criteria for indication of frenectomy. Study design The experimental group is composed of 10 childrens who visited our department of oral and maxillofacial surgery, dental hospital, Chonbuk university, due to ankyloglossia and articulation problem,. The average age is 5 Y 7M, M : F ratio is 4 : 1 at the time of speech test. The VPI consonant discrimination degree, PPVT, PCAT, Nasometer II, Visi-Pitch test result were obtained from each group. Result : There was significant difference for 'language development' through PPVT. Except 3 members of experimental group, all remainder showed retardation for 'language development'. For 'errored consonant rate', data showed more higher scores in alveolar consonant. There 'consonant error' in experimental group, mostly showed 'alveolar consonant', also a major modality of 'consonant error' was mostly distortion. Conclusion : We can judge the severity of ankyloglossia patient by examinig language development degree & speech test of 'alveolar consonant' . And we can make a decision for frenulotomy using these results.

There is close relationship between intraoral structural anomaly and speech- functional problem. Patient with cleft palate patients & ankyloglossia is a typical example, patients with structural anomaly is repaired toward normal structure by operation. Ankyloglossia may cause functional limitation even after adequate surgical treatment speech disorders being one of them. Interindividually, they vary a lot, showing typical articulation specifics. The objective of this study was to evaluate and compare speech for children with ankyloglossia and general public, to determine whether ankyloglossia is associated with articulation problem. We wanted to present criteria for indication of frenectomy. The group of subject is composed of 10 childrens with ankyloglossia and articulation problem, visited the Oral and Maxillofacial surgical unit, dental hospital, Chonbuk university. The average age is 5 Y 7M, M : F ratio is 8 : 2 at the time of speech test. Control group is composed of 10 members without oral structural anomaly. The average age is 5 Y 10M, M : F ratio is 3 : 7 at the time of speech test. Outcomes were measured the PPVT(Peabody Picture Vocabulary Test), PCAT(Picture Consonant Articulation Test), Nasometer II test result obtained each group, statistically measured by Mann-whitney's U Test. There was no difference for 'chronological age-age equivalent' between two group. There was significant difference for 'consonant accuracy' between two group, showed more lower scores in subject group. There was more 'consonant error' in subject group, mostly showed/1/,/s/. A major modality of 'consonant error' was mostly distortion and replacement. There was no significant difference between two group for nasality.

Recently, dental laser have been applied for removal of soft tissues, hemostasis and blood coagulation, removal of benign and malignant tumor, treatment of leukoplakia, aphthous ulcer and herpetic lesion, implant second surgery, removal of granulation tissue, frenectomy, clinical crown lengthening, gingivectomy, gingivoplasty, and treatment of dentin hypersensitivity. Even though the frequency of laser treatment is increasing, the research on the healing process after gingivectomy using pulsed Nd : YAG laser is very rare. The purpose of this study was to observe and compare the wound healing after gingivectomy using scalpel and pulsed Nd : YAG laser in the rat. Gingivectomy was performed using pulsed Nd : YAG laser(SUNRISE Technologies, U.S.A., 1.5 Watts, 10 pps) on the buccal gingiva of right maxillary first molar and using scalpel(No.12) on the contralateral side. Those sites treated by surgical scalpel were designated as the control, and by pulsed Nd : YAG laser as the experimental group. Animals were sacrificed at 1, 2, 3, 5, 7, 11 and 14 days postoperatively, and specimens were histologically observed under light microscope. The results were as follows : 1. Clinical observation Normal color and shape were observed at the 5th day ill the control group and the 7th day in the experimental group. 2. Histologic findings 1) In the control group, denser inflammatory infiltration was observed. 2) Epithelialization started at the 2nd day in the control group, similar to the experimental group, and completed at the 11th to the 14th day postoperatively. 3) In the experimental group, connective tissue showed the vacuole formation and degenerative change during early healing period. Healing of connective tissue was slower in the experimental group than in the control group by 2 days. 4) In the both groups, wound healing was completed at the 2nd week. From this study, gingivectomy using pulsed Nd : YAG laser seems to result in a little delayed wound healing process, compared to the gingivectomy using scalpel. Considering the clinical advantages of laser surgery, pulsed Nd : YAG laser might be useful device for gingivectomy.
