Eighty\u2010two patients with periodontitis were treated in a split mouth design with coronal scaling, root planing, modified Widman surgery, and flap with osseous resectional surgery. Patients were evaluated prior to therapy, 4 weeks post\u2010Phase I therapy, 10 weeks post\u2010Phase II therapy, and at yearly intervals during 2 years of maintenance therapy. The tooth\/site groupings evaluated were: 1) interproximal sites of single rooted teeth (T1), 2) facial and lingual sites of single rooted teeth (T<jats:sub>2<\/jats:sub>), 3) nonfurcation sites of molar teeth (T<jats:sub>3<\/jats:sub>), and 4) furcation sites of molar teeth (T<jats:sub>4<\/jats:sub>). Following 2 years of maintenance, no clinically significant differences in probing depth reduction or probing attachment loss were present between the four tooth\/site groupings in 1 mm to 4 mm sites. T<jats:sub>2<\/jats:sub> had the greatest decrease of probing depth in 5 mm to 6 mm sites followed by T1, T3 and T4. T<jats:sub>1<\/jats:sub> and T<jats:sub>2<\/jats:sub> showed a greater gain of probing attachment followed by T<jats:sub>3<\/jats:sub> and then T<jats:sub>4<\/jats:sub>. T<jats:sub>1<\/jats:sub> and T<jats:sub>2<\/jats:sub> had the greatest decrease of probing followed by T<jats:sub>3<\/jats:sub> which was greater than T<jats:sub>4<\/jats:sub> in \u2265 7 mm sites. T4 had significantly less probing attachment gain than the other groups. There was a trend for T<jats:sub>1<\/jats:sub> and T<jats:sub>2<\/jats:sub> to have less gingival bleeding post\u2010therapy and for T<jats:sub>2<\/jats:sub> to have less plaque accumulation than the other groups at both pre\u2010 and post\u2010therapy examinations. <jats:italic>J Periodontol 1990; 61:173\u2013179.<\/jats:italic><\/jats:p>","DOI":"10.1902\/jop.1990.61.3.173","type":"journal-article","created":{"date-parts":[[2012,3,21]],"date-time":"2012-03-21T06:33:27Z","timestamp":1332311607000},"page":"173-179","source":"Crossref","is-referenced-by-count":17,"title":["Responses of Four Tooth and Site Groupings to Periodontal Therapy"],"prefix":"10.1002","volume":"61","author":[{"given":"Wayne B.","family":"Kaldahl","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kenneth L.","family":"Kalkwarf","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kashinath D.","family":"Patil","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael P.","family":"Molvar","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[1990,3]]},"container-title":["Journal of Periodontology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/aap.onlinelibrary.wiley.com\/doi\/pdf\/10.1902\/jop.1990.61.3.173","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,19]],"date-time":"2025-10-19T13:58:49Z","timestamp":1760882329000},"score":1,"resource":{"primary":{"URL":"https:\/\/aap.onlinelibrary.wiley.com\/doi\/10.1902\/jop.1990.61.3.173"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1990,3]]},"references-count":0,"journal-issue":{"issue":"3","published-print":{"date-parts":[[1990,3]]}},"alternative-id":["10.1902\/jop.1990.61.3.173"],"URL":"https:\/\/doi.org\/10.1902\/jop.1990.61.3.173","archive":["Portico"],"relation":{},"ISSN":["0022-3492","1943-3670"],"issn-type":[{"type":"print","value":"0022-3492"},{"type":"electronic","value":"1943-3670"}],"subject":[],"published":{"date-parts":[[1990,3]]}}}
