치경부 병소는 부적절한 칫솔질, 화학적 침식 및 차아의 굴곡 등의 여러 원인에 의해 크게 cervical abrasion, erosion 및 abfraction의 형태로 나타난다. 최근 노령 환자층의 증가와 치주 치료에 의한 구강내 치아 잔존율의 증가는 치경부 병소의 증가를 가져왔다. 이러한 치경부 병소는 지각과민증, 우식 및 심미적 이유 등으로 수복을 시행하며 구치부위에 작은 우식이 없는 치경부 병소가 있는 경우 환자에게서 지각과민증를 유발하지 않는 경우라면 수복을 시행하지 않을 수도 있지만, 많은 예에서 더 이상의 치아 및 치주 조직의 손상을 억제하고 치수의 보호를 위해서 수복을 시행한다. 특히 전치부의 경우에는 병소가 작고 우식에 이완되지 않았다 할지라도 그 심미적 측면 때문에 수복을 시행하는 예가 증가하고 있다.(중략)

Decalcification of the buccal surface of the teeth often occurs during fixed orthodontic treatment. This case report describes two cases in which cervical decalcificated teeth that occurred during orthodontic treatment were treated with direct resin veneer restoration. Early lesions without caries can be remineralized through periodic fluoride application, diet control, and oral hygiene improvement. As it progresses, appropriate repair treatment is required, and it is more preferable to focus on prevention rather than treatment after the occurrence of the lesion.

치경부에 발생된 병소 부위(cervical lesion)는 "우식성 병소(caries lesion)"와 "비우식성 병소(non-caries lesion)"로 분류할 수 있다. 우식성 병소는 구강 내 세균들의 활동에 기인하여 발생된 병소로서 경조직 손상 부위의 수복과 함께 우식이 재발하지 않도록 체계적으로 대응하는 것이 필요하다. 비우식성 병소는 산성 물질, 저작력 및 이물질에 의한 마모 작용과 같은 다양한 원인에 의해 발생될 수 있으며, 수복 치료에 앞서 병소에 발생 원인을 규명하는 것이 중요하다. 먼저 병소 유발 원인에 대한 분석과 이에 대한 적절한 조치를 취한 후에 수복 치료를 시행하는 것이 바람직하다. 심미적인 요구가 높은 치경부 병소의 수복을 위하여 사용될 수 있는 재료는 "불소를 방출하는 재료"와 "불소를 방출하지 않는 재료"로 나뉘어지는데, 세균의 활동에 의해 형성된 우식성 병소의 수복에는 불소를 방출하는 재료를 사용하는 것이 추천된다. 우수한 심미성과 보다 강력한 유지력이 요구되는 경우에는 복합 레진계 수복 재료들을 사용하여 수복하게 되는데, 이 경우에는 "접착 술식(bonding procedure)"이 중요한 역할을 수행하게 된다. "접착 술식"은 수복물의 일차적인 유지 뿐 아니라 지각과민을 해소하고 2차 우식을 방지하며, 궁극적으로 수복물의 수명을 좌우하는 결정적인 역할을 수행한다. 자연 치아를 최대한 보존하고자 하는 "최소침습(minimum intervention)" 개념에 바탕을 두고 세심하게 형성된 와동에 각각의 증례에 최적화된 수복 재료를 선택하여 수복치료를 시행한다면 보다 심미적이고 환자가 편안한 치경부 수복물을 완성할 수 있을 것이다.

1. The author have had a case of class V and class Ⅲ combined carious lesion extended on to root surface of upper right lateral incisor. 2. The patient was 40 years old female. 3. After routine root canal treatment of the tooth, the gingival flap was made by vertical incision on gingival tissue between distal surface of upper right lateral incisor and mesial surface of upper right canine. 4. Cavity preparation and amalgam filling on the carious lesion were performed and the flap was sutured.

Surgical extrusion, immediate extrusion following tooth luxation, is a method to preserve one's natural tooth and achieve esthetic restoration without additional periodontal surgery when subgingival dental caries or crown fracture occurs. A 16-year-old male was referred to the clinic from the department of operative dentistry for the esthetic restoration of maxillary left lateral incisor. Due to the crown to root fracture, the tooth was endodontically treated with a buccal crown length of 4 mm. When the palatal flap was elevated, the mesiopalatal cervical fracture area was situated 3-4 mm subgingivally. Crown lengthening was achieved through surgical extrusion. After 3 months of clinical observation and provisional restoration, the maxillary left central incisor was restored with all ceramic crown and obtained a satisfactory clinical result.

The primary objective of pulp treatment is to maintain the integrity and health of the oral tissues. The most important and difficult aspect of pulp therapy is determining the health of the pulp, or its stage of inflammation, so that a decision can be made regarding the best form of treatment. Immature permanent teeth are good candidates for many pulp healing procedures, due to their rich blood supply, which is believed to enhance the pulp's ability to react successfully to various insults. Healing was considered to have taken place when the tooth fulfilled the following criteria: 1. Abscence of clinical symtoms 2. Radiographic evidence of dentin bridge formation 3. No intrapulpal or periapical pathosis was evident radiographically 4. Continued root development and closure of the apex in immature teeth 5. Normal dentin apposition in mature teeth 6. Positive response to electrical pulp test This presents a report of cases in which immature permanent teeth, pulp-exposed by caries or trauma, was treated successfully by partial pulpotomy.

Dens evaginatus is a tooth with cylindrical enamel projection which forms a nodule on occlusal surface. It could be explained as outward overgrowth of inner enamel epithelium or localized hyperplasia of pulpal mesenchymal tissue during tooth development. A problem is that it is likely to be worn out or fractured by mastication ensuing pulpal inflammation. It is occasionally found on the lingual surface of upper anterior teeth as well, called talon cusp. Dens invaginatus is a tooth with deep lingual pit made by invagination of lingual enamel epithelium during tooth development while it is considered normal in terms of size and shape. Radiographically, a part of cervical enamel shows inward growth forming cavity and it is reasonable to say that the base is possibly open to pulpal cavity since they are very close. Talon cusp and dens invaginatus are relatively common abnormality of shape. However it becomes the opposite if the two exist in the same tooth. Once the talon cusp is broken by occlusal force or fissure between cusps is decayed, the complicated structure of canals makes the pulpal treatment difficult. Preventive treatments such as occlusal equilibrium and sealant, and regular oral examination should be preceded and thorough understanding of canal shape, using radiography, is required when pulpal treatment is necessary. This report is about a 9- year-old boy(lower left central incisor), a 8-year-old girl(upper right central incisor), and a 7-year-old boy(upper right central incisor), who have dens invaginatus and talon cusp in the same teeth. The first and the second patients are under pulpal treatments, and the last one is being observed showing no pathologic impressions.
