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).

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%).

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.

All prosthetic and restorative therapies require a healthy periodontium as a prerequisite for success. Understanding of the concepts of periodontal-restrorative interaction, especially with regard to interactions at the gingival margin is important. The aim of this article gives the information about the essential considering factor for successful prosthesis; biologic width, periodontal biotype, width of attached gingiva, margin of restoration. If a restorative margin must be extended below the gingival margin, it is critical that adequate band of attached gingiva is present, the margin does not violate the biologic width, the margin is closed and properly finished.

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.

The purpose of this study was to evaluate clinical changes in graft size after treatment with strip gingival autograft in human. 57 premolar teeth in 27 patients having the following mucogingival problems were selected. The width of extension, attached gingiva including free marginal gingiva, width of transplant and clinical sulcus depth were measured at the initial examination, 2, 12 and 24 weeks following the strip gingival autograft and free gingival autograft. The change of width of extension, attached gingiva including free marginal gingiva, width of transplant and clinical sulcus depth according to healing process in both graft procedures was statistically analyzed by repeated measure ANOVA test and independent t-test using SPSS program. The results were as follows : 1. The change of keratinized gingiva in both graft procedures was increased significantly at 24 weeks post-op. 2. The clinical sulcus depth exhibited no marked changes throughout the entire investigation in both graft procedures. 3. No dimensional variation was seen in graft size in both graft procedures. 4. Shrinkage did not differ significantly in both graft procedures. From the day of grafting to 24 weeks after surgery the percentages of shrinkage were : strip gingival autograft 28% and free gingival autograft 29%.
