The purpose of this study was to investigate the width of attached gingiva of young adults with healthy gingiva. We compared the differences according to the tooth location. The width of attached gingiva of maxilla and mandible was measured by histochemical method. The results were as follows: 1. The width of buccal keratinized gingiva in maxilla was widest in incisors(5.2-5.6mm) and narrowest in first bicuspids(4.4-4.5mm). 2. The width of buccal keratinized gingiva in mandible was widest in incisors(4.3-4.5mm) and narrowest in first bicuspids(3.2-3.3mm). 3. The width of lingual keratinized gingiva in mandible was widest in first molars(5.5-5.6mm) and narrowest in incisors(2.9-3.0mm). 4. The width of buccal attached gingiva in maxilla was widest in incisors(4.1-4.4mm) and narrowest in molars (3.0mm). 5. The width of buccal attached gingiva in mandible was widest in incisors(3.2-3.4mm) and narrowest in second molars (1.7-1.8mm). 6. The width of lingual attached gingiva in mandible was widest in first molars(3.5-3.7mm) and narrowest in incisors(1.9-2.1mm).

This study was performed to evaluate the effect on the formation of keratinized attached gingiva when free gingival graft with strip technique was used. After the partial thickness flap was prepared, it was positioned apically more than 7mm using mucoperiosteal suture. At the donor site, strip was achieved with 2mm width, less than 1mm thickness, (mesiodistal teeth length + 6)$^{\ast}$2 mm length. Then, it was divided into 2 same pieces and located at the recipient bed apico-coronally with more or less 3mm interval. Follow-up check was made at 1,2,4,8,12 weeks after the operation. The results of this study were as follows : 1. The inter-strip space was mostly filled with keratinized attached gingiva. 2. The contraction of the graft was nigligible, and 92% of planned area was filled with keratinized attached gingiva. 3. The inconvenience of the patients at donor site was minimal. 4. The width of the strip was widened. In conclusion, free gingival graft using strip technique is useful to achieve the keratinized attached gingiva maximally with free gingival graft minimally and to minimize the inconvenience of donor palatal site of the patients.

The purpose of this study was to investigate the width of attached gingiva of 414 subjects with healthy gingiva, or early stage of gingivitis. We compared the differences according to the tooth location, age (Yonger group : $14{\sim}30$, Older group : $31{\sim}67$) and gender. In addition, we compared the width of attached gingiva in the subjects with less than 2 sites of gingival recession($Re{\leq}2$) and the subjects with more than 3 sites of gingival recession($Re{\geq}3$) to study the relationship between the gingival recession and the width of attached gingiva. The results were as follows : 1. The width of keratinized gingiva was widest in maxillary incisors($5.3{\pm}1.4mm$) and narrowest in mandibular right 1st bicuspid and mandibular right and left 2nd molars($3.5{\pm}1.1mm$). 2. The width of attached gingiva was widest in maxillary right central incisor($3.8{\pm}1.5mm$) and narrowest in mandibular right 2nd molar($1.2{\pm}1.0mm$). 3. In the comparison between the age groups, the width of keratinized in older group was significantly (p<0.05) wider than that in younger group in maxillary right and left 1st bicuspids, mandibular right and left 1st and 2nd molars, maxillary right and left cuspids and mandibular right 1st bicuspid. There was no significant difference in the width of attached gingiva between the two groups except for maxillary right and left 1st molars and maxillary left 2nd molar. 4. In the comparison between male group and female group, in maxillary right and and left lateral incisors and cuspids, mandibular right and left cuspids and 1st bicuspids, the width of attached gingiva in female was significantly(p<0.05) wider than that in male group. 5. In the comparison between the Re 3 group and Re 2 group, there was no significant difference except for maxillary right and left 2nd molars and maxillary left 1st molar. 6. The frequency of gingival recession was m the order of mandibular right 1st bicuspid(16.6%), maxillary right 1st bicuspid(13.7%), maxillary and mandibular left 1st bicuspids (13.4%), mandibular left cuspid (10.5%), maxillary left and mandibular right cuspids(10.1%) and maxillary right cuspid(7.9%).

The present study examines the effects of orthodontic treatment of surgically exposed impacted upper canines or ectopically erupted upper canines to periodontal condition and whether various opening procedures have significant difference in postoperative periodontal status. The subjects included 23 orthodontic patients(7 men, 16 women) with unilateral upper canine impaction treated either with closed eruption technique(group I), with apically positioned flap procedure (group II), and those with canines ectopically erupted through keratinized gingiva (group III). In each subject, the ectopic canine was orthodontically aligned, and changes in periodontal tissue were assessed by measuring keratinized gingival width, attached gingival width, probing depth and bone probing depth. In all three groups, the width of keratinized gingiva was preserved while showed no signs of detrimental periodontal condition such as gingival recession. In all three groups, no significant difference in periodontal pocket depth from control was observed. The width of attached gingiva was significantly greater in patients treated with apically positioned flap procedure(group II) than in patients on other groups.

Narrow zone of attached gingiva and shallow vestibule around the implants might contribute to difficulty of cleasing, periimplant mucositis caused by incomplete cleansing and further peri-implantitis. The aim of this case report is to present modification of soft tissue biotype around the implants by free gingival grafts according to timing of surgical intervention and shape of free gingiva. A 44 year-old male patient had a missing area on lower right second molar area with 1 to 2 mm of narrow attached gingiva zone and wanted to be treated by implant placement. In radiographic analysis, there was enough alveolar bone to install an implant, free gingiva from hard palate was grafted following implant placement using double layer flap. The width of attached gingival was increased to 4 to 5mm and well maintained during 5 months of follow up. A 69 year-old female patient also had a missing area on lower right first and second molar area with 1 to 2 mm narrow attached gingiva. Since she had systematically angina pectoris and dental phobia, minimal invasive free gingival graft after implants placement was planned. After 2 months of implant surgery, free gingival graft surgery was performed with healing abutments connection. The grafted gingiva was composed of two strip shaped free gingiva, and they were immobilized by periodontal pack. The width of attached gingival was increased to 4 to 5mm and well maintained during 10 months of follow up. With prosthesis delivery, the patients recovered ideal periodontal environment around implants and masticatory function. In conclusion, periodontal health and masticatory function could be achieved through implant placement and free gingival graft.

건강한 치주조직을 유지하기 위해서는 적절한 폭경의 부착치은이 필요하다. 이러한 부착치은의 폭경은 연령에 따라서 변화한다는 보고가 있다. 그러나 그 정상치에 대한 보고는 저자들마다 차이를 보이며 또한 한국인에서의 정상 평균값에 대한 연구는 미흡한 실정이다. 본 연구의 목적은 악골의 발육 및 치아의 맹출과 관련하여 유치열기로부터 초기영구치열기까지의 부착치은의 폭경 및 치은열구 깊이의 변화 양상을 조사하고, 한국인 아동의 정상치를 구하는 것이다. 삼성서울병원 소아치과에 내원한 4세에서 14세 사이의 유치열기, 혼합치열기 및 영구치열기 아동88명을 대상으로 유치열기($4{\sim}6$세)에서는 유중절치와 제1유구치, 혼합치열기($7{\sim}10$세)에서는 중절치, 제1유구치 및 제1대구치, 영구치열기($10{\sim}14$세)에서는 중절치, 제1소구치 및 제1대구치에서 협측 부착치은의 폭경과 치은열구 깊이를 치주탐침으로 측정하여 비교하였다. 상하악 제1대구치 부착치은의 폭경은 치아맹출 후 연령에 따라서 증가하였다(p<0.05). 하악유전치을 제외한 모든 실험 치아에서 맹출 직후 치은열구 깊이가 증가하는 것을 보였으며 부착치은의 폭경은 상대적으로 줄어들었다(p<0.05). 이러한 결과는 부착치은의 폭경이 유치열기부터 영구치열까지 연령에 비례하여 일정하게 증가하지 않는다는 것을 의미한다.
