The purpose of this study is to evaluate clinically the periodontal healing of root fracture treatment using adhesive resin cement. In 22 patients, 23 teeth with vertical root fractures were treated with 4\u2010META\/MMA\u2010TBB resin cement. Eleven fractured roots were bonded through the root canal (group A) and 12 fractured roots were bonded extra\u2010orally and replanted (group B). All teeth were then restored with full cast crowns (<jats:italic>n<\/jats:italic>=20) or coping (<jats:italic>n<\/jats:italic>=3). Mean probing depth was 6.6 mm at pre\u2010treatment and 4.4 mm 6 months after the treatment in group A, and 7.4 mm and 4.6 mm, respectively, in group B. Bleeding scores were 100% at pre\u2010treatment and 36.4% after 6 months in group A and 91.7% and 8.3%, respectively in group B. Radiographic bone level was 56.8% at pre\u2010treatment and 59.1% after 6 months in group A, and 18.8% and 29.2%, respectively, in group B. Two roots of group A and three roots of group B were extracted due to refracture, deterioration of periodontal inflammation, mobility, and luxation. The remaining roots (<jats:italic>n<\/jats:italic>=18) presented no discomfort to the patients and there was no deterioration of periodontal conditions over a mean period of 33 months (range 14\u201374 months) in group A and over a mean period of 22 months (range 6\u201348 months) in group B. There was no ankylosed teeth nor was any root resorption detected. The results suggested that the treatment of vertical root fracture using 4\u2010META\/MMA\u2010TBB resin has good prognostic possibilities.<\/jats:p>","DOI":"10.1034\/j.1600-9657.2001.170407.x","type":"journal-article","created":{"date-parts":[[2003,3,11]],"date-time":"2003-03-11T16:22:39Z","timestamp":1047399759000},"page":"174-179","source":"Crossref","is-referenced-by-count":56,"title":["Periodontal healing after bonding treatment of vertical root fracture"],"prefix":"10.1111","volume":"17","author":[{"given":"Tsutomu","family":"Sugaya","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masamitsu","family":"Kawanami","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroshi","family":"Noguchi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroshi","family":"Kato","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nobuo","family":"Masaka","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2001,12,21]]},"reference":[{"key":"e_1_2_5_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0099-2399(83)80150-2"},{"key":"e_1_2_5_3_2","first-page":"29","article-title":"Treatment of fractured and avulsed teeth","volume":"38","author":"Andreasen JO","year":"1971","journal-title":"J Dent Child"},{"key":"e_1_2_5_4_2","first-page":"607","article-title":"Diagnosis and management of vertical root fracture","volume":"61","author":"Schetritt A","year":"1995","journal-title":"J Can Dent Assoc"},{"key":"e_1_2_5_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0099-2399(84)80161-2"},{"key":"e_1_2_5_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0099-2399(06)80850-2"},{"key":"e_1_2_5_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0099-2399(96)80245-7"},{"key":"e_1_2_5_8_2","first-page":"156","article-title":"Long\u2010term observation of fractured tooth roots preserved by adhesion","volume":"13","author":"Masaka N","year":"1995","journal-title":"Adhesion Dent"},{"key":"e_1_2_5_9_2","volume-title":"Textbook of periodontia","author":"Miller SC","year":"1938"},{"key":"e_1_2_5_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0300-9785(84)80069-1"},{"key":"e_1_2_5_11_2","first-page":"479","article-title":"Treatment and prognosis of a vertically fractured maxillary molar with widely separated segments: a case report","volume":"26","author":"Takatsu T","year":"1995","journal-title":"Quintessence Int"},{"key":"e_1_2_5_12_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-9657.1998.tb00855.x"},{"key":"e_1_2_5_13_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-9657.1999.tb00749.x"},{"key":"e_1_2_5_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0099-2399(06)80068-3"},{"key":"e_1_2_5_15_2","first-page":"1445","article-title":"Treatment of vertically fractured root by cohesion. 1.
