  • Author have measured the depth of gingival sulcus of the primary teeth. 333 teeth were selected from the children who attended on the department of pedodontic, College of dentistry, Yonsei University, and kindergarten children at Won Ju city aged from 1 year 8 months to 10 year 2 months. 1998 point were measured. The results were as follows. ; 1. Facial surface was the shallowest in sulcus depth compared with other surfaces. It was 1.56 mm. The depth of sulcus in lingual surface was deeper than facial. 2. The deepest part of each surface was mesial and distal, There were no statistical differences between mesial and distal part of the sulcus depth. 3. The mean sulcus depth of each tooth was as follows. Primary central incisor.....1.71mm. Primary canine....1.75mm. Primary second molar.....2.03mm. 4. The mean sulcus depth of upper was 1.86mm, and the lower was 1.76mg. The upper tooth was deeper than lower in sulcus depth. 5. The lower primary central incisor had the shallowest sulcus and the upper 2nd primary molar had the deepest compared with other tooth. 6. There wasn't specific statistical differences between the age groups of primary dentition and mixed dentition.

  • A total of 200 patients, ranging in age from 20 to 60 years, were selected for the study. Each had at least one tooth which was restored with complete cast gold crown and a nonrestored contralateral tooth with no clinical evidence of caries and periodontal disease. The gingival tissues adjacent to the crowned and nonrestored teeth were examined to determine the evaluation of the severity of inflammation and probed to determine individual pocket depth. The findings are listed here. 1. The average sulcus bleeding index of the gingival tissues adjacent to crowned teeth was 1.99. The average sulcus bleeding index of the gingival tissues adjacent to nonrestored teeth was 0.67. 2. The average gingival sulcus depth adjacent to crowned teeth was 2.19mm. The average gingival sulcus depth adjacent to non restored teeth was 1.68mm. 3. No difference could be found between the average gingival sulcus bleeding index and average gingival sulcus depth of male and those of female. 4. The difference between sulcus bleeding index of the gingival tissues adjacent to crowned teeth and sulcus bleeding index of the gingival tissues adjacent to nonrestored teeth increased with increased age of the cast crown.

  • Background and Objectives : Sulcus vocalis could be classified into type I, type IIa, and type IIb. There have been a little reports about voice quality and treatment results related with types of sulcus vocalis. The authors conducted an analysis of voice and treatment according to different types of sulcus vocalis. Materials and Methods : This study was based on a retrospective chart review. The sulcus types were classified into type I and type II. Objective and subjective voice assessments were analyzed. Patients were treated individually with voice therapy, percutaneous steroid injection, and injection laryngoplasty. Comparison was performed on the voice difference between type I group and type II group, and between pre-treatment and post-treatment of each types. Results : One hundred and one patients were enrolled into this study, and 49 patients were type I and 52 patients were type II. Type I group showed longer mean maximal phonation time (MPT) than type II group, although other voice parameters didn't show any difference between two groups. Even after the management, almost all of the voice parameters didn't show improvement except MPT of type II group. Conclusion:Although the type I sulcus has been known as a non-pathologic lesion, it can result in some degree of voice change and discomfort, and thus need an active management. In this study, voice therapy, percutaneous steroid injection, and injection laryngoplasty showed limited effect to the both types of sulcus vocalis. Further studies for management of sulcus vocalis were needed.

  • Sulcus vocalis remains a surgical challenge despite many recent advances in laryngomicrosurgeries. We previously reported that 585-nm Pulsed dye laser (PDL) exerts favorable outcome in treatment of sulcus vocalis due to its therapeutic effects of collagen rearrangement and improved wound remodeling. In spite of the usefulness of PDL glottoplasty for treating sulcus vocalis, the device is no more available in the country. It prompted us to focus another angiolytic laser ; 532-nm KTP laser which has similar mechanisms of action and has been used for treatment of other laryngeal lesions elsewhere. Herein, we present a case of sulcus vocalis successfully treated with KTP laser. A patient underwent laryngomicrosurgery with angiolytic KTP laser (KTP glottoplasty) by the same surgical procedure with PDL glottoplasty. After the surgery, the patient presented improved voice outcome in time without complications.

  • Wettability of addition silicone impression material is very important property for making an accurate restoration. This study examined the impression quality in clinical condition and the wettability of impression and die material. Four commercially available addition silicone impression material (Express, Examix, Contrast, Perfect) and three die materials (Die-Keen, Vel-Mix, Fuji-Rock) were studied. A total of 50 putty/wash and heavy body/wash impressions of wet intact permanent molar teeth were examined for definition of the gingival sulcus reproduction and then classified in quality ranking. The percentage of the sulcus reproduction ability of each material was calculated from the sulcus depths of cross-sectioned epoxy resin casts from the impressions and clinically measured sulcus depths, The same impression materials were used to produce 3 groups of die stone casts form void entrapment die had been exposed to milk. Voids in the impression body and stone casts ere counted under a stereoscopic microscope. From the experiment, the following results were obtained : 1. Sulcus reproduction ability of additional silicone impression material were diminished in order of Express, Examix, Perfect, Contrast. The significant difference was found between Perfect and other material. Heavy body/wash combination was superior In putty/wash method n Perfect impression material. 2. In direct observation, Contrast showed least void in impression body but correlations ere not found between sulcus reproduction and void production. 3. In void entrapment laboratory test, wettability were diminished in order of Examix, Contrast, Express, Perfect. Clinical impression recording seems not to correlate with laboratory test. 4. The wettability of die material to impression material was not different in Express, Examix, Contrast. But, in Perfect, Die-Keen had superior wettability to others.

  • 목 적:신생아, 특히 미숙아에서 재태기간의 정확한 측정은 환자의 상태와 질병을 이해하여 치료하고 예후를 예상하는데 필수적이다. 이에 저자들은 신생아 뇌 초음파 검사시 최소한의 시간과 기구의 추가 사용으로 간편하게 정확한 재태기간을 추정할 수 있는 방법을 연구하였다. 방 법:일반적인 뇌 초음파 검사를 시행한 후 5-12 Mhz의 고해상도 선형 탐촉자를 사용하여 대천문을 통하여 관상면의 영상을 얻었고 여기에서 대뇌반구의 깊이와 뇌량의 두께 및 대상고랑의 깊이를 측정하여 재태기간과의 상관관계을 구하였다. 결 과:대뇌반구의 깊이, 뇌량의 두께 및 대상고랑의 깊이 중 재태기간과 가장 상관관계가 높은 측정치는 대상고랑의 깊이로 Pearson 상관계수 0.878을 보였다(P=0.000). 또한 대상고랑의 깊이가 0.55 cm 이상인 경우 단 두 례를 제외하고 모두 재태기간이 37주 이상이었고 대상고랑의 깊이가 0.35 cm 미만인 경우는 모두 34주 미만이었다. 결 론:고해상도 뇌 초음파 검사를 통해 측정된 대상고랑의 깊이는 신생아의 정확한 재태기간 측정에 유용하게 이용될 수 있다. 그러나 보다 더 많은 수의 신생아를 대상으로 한 대규모 연구가 필요할 것으로 생각된다.

  • Wettability of addition silicone impression material is very important property for making an accurate restoration. This study examined theimpression quality in clinical condition and the wettability of impression material. Three commercially available addition silicone impression material (Imprint; 3M, USA, Examix; GC, Japan, Perfect; Handae, Korea) were studied. A total of 90 putty/wash impressions of semi-dried premolars and wet molar teeth were examined for void production in impression body. The percentae of the sulcus reproduction ability of each material was calculated from the sulcus depths of cross-sectioned casts from the impressions with stereomicroscope. Three impression materials were used to produce die stone casts from vcid entrapment die. Voids in the stone casts were counted with the stereomicroscpe. From the experiment, the following results were obtained: 1. In direct observation, Imprint showed greatest numbers of void in impression body (P<.001).However, correlations were not found between sulcus reproduction and void production. 2. Sulcus reproduction ability of additional silicone impression material was diminished in order of Imprint, Examix, Perfect. The significant difference was found between Imprint and other material (P<.001). 3. In void entrapment laboratory test, void productions was diminished in order of Examix, Imprint, Perfect. All voids in casts were less in delayed poured cast than immediately poured cast. 4. Especially, the stone pouring time of Perfect impression material should be delayed.
