Ambiguous results about the additional clinical benefit of a second scaling procedure exist. Therefore, we performed a prospective study comparing the clinical results of repeated subgingival scaling versus periodontal surgery in 30\u2010 to 40\u2010year\u2010old subjects with generalized advanced periodontitis.<\/jats:p><jats:p><jats:bold>Methods:<\/jats:bold> Twenty\u2010six subjects (mean age, 37 \u00b1 3 years) were treated after an initial examination (t<jats:sub>1<\/jats:sub>), initial subgingival scaling, and baseline examination (t<jats:sub>2<\/jats:sub>) with a randomly assigned second subgingival scaling (test) and periodontal surgery (control) in a split\u2010mouth design. The final examination (t<jats:sub>3<\/jats:sub>) took place 6 months postoperatively. Intraindividual comparisons of mean PD and clinical attachment level (CAL) were analyzed.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> PD was reduced from 4.1 \u00b1 0.2 mm initially (t<jats:sub>1<\/jats:sub>) to 3.1 \u00b1 0.1 mm at baseline (t<jats:sub>2<\/jats:sub>), and to 2.9 \u00b1 0.1 mm at the end of the study (t<jats:sub>3<\/jats:sub>) for the test sites; and from 4.5 \u00b1 0.2 mm (t<jats:sub>1<\/jats:sub>) to 3.5 \u00b1 0.1 mm (t<jats:sub>2<\/jats:sub>), and 3.1 \u00b1 0.1 mm (t<jats:sub>3<\/jats:sub>) for the control sites. The total PD decrease from t<jats:sub>1<\/jats:sub> to t<jats:sub>3<\/jats:sub> was significant (<jats:italic>P<\/jats:italic> &lt;0.001) for both therapies. PD reduction from t<jats:sub>2<\/jats:sub> to t<jats:sub>3<\/jats:sub> was only significant (<jats:italic>P<\/jats:italic> &lt;0.001) for control sites, resulting in a significant (<jats:italic>P<\/jats:italic> = 0.010) difference between test and control at the final examination. CAL increased 0.2 \u00b1 0.1 mm (t<jats:sub>2<\/jats:sub>) plus 0.3 \u00b1 0.1 mm (t<jats:sub>3<\/jats:sub>) for the test sites and 0.2 \u00b1 0.1 mm (t<jats:sub>2<\/jats:sub>) plus 0.2 \u00b1 0.1 mm (t<jats:sub>3<\/jats:sub>) for the control sites. Total CAL gain was statistically significant for the test and control sites. CAL gain from t<jats:sub>2<\/jats:sub> to t<jats:sub>3<\/jats:sub> was only significant (<jats:italic>P<\/jats:italic> = 0.022) for the test sites.<\/jats:p><jats:p><jats:bold>Conclusions:<\/jats:bold> Both treatments reduced PD and increased CAL. A second subgingival scaling resulted in significant additional CAL gain and reduced the need for surgery.<\/jats:p>","DOI":"10.1902\/jop.2008.070380","type":"journal-article","created":{"date-parts":[[2008,6,5]],"date-time":"2008-06-05T08:53:34Z","timestamp":1212656014000},"page":"1006-1013","source":"Crossref","is-referenced-by-count":14,"title":["Repeated Scaling Versus Surgery in Young Adults With Generalized Advanced Periodontitis"],"prefix":"10.1002","volume":"79","author":[{"given":"J\u00f6rgen","family":"K\u00f6nig","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christian","family":"Schwahn","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jutta","family":"Fangh\u00e4nel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jutta","family":"Pl\u00f6tz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas","family":"Hoffmann","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas","family":"Kocher","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2008,6]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-051X.1984.tb01309.x"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-051X.1984.tb00839.x"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-051X.29.s3.9.x"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-051x.2000.027008590.x"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.1996.67.4.367"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-051X.1998.tb02473.x"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-051X.2005.00776.x"},{"issue":"2","key":"e_1_2_7_9_1","first-page":"6","article-title":"Clinical significance of non\u2010surgical periodontal therapy: An evidence\u2010based perspective of scaling and root planing","volume":"29","author":"Cobb CM","year":"2002","journal-title":"J Clin Periodontol"},{"key":"e_1_2_7_10_1","first-page":"414","volume-title":"Treatment planning","author":"Lindhe J","year":"2003"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.1995.66.5.321"},{"key":"e_1_2_7_12_1","first-page":"100","article-title":"An effective method of personal oral hygiene","volume":"106","author":"Bass CC","year":"1954","journal-title":"J LA State Med Soc"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1177\/08959374930070020501"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.1972.43.1.38"},{"key":"e_1_2_7_15_1","doi-asserted-by":"publisher","DOI":"10.1016\/0030-4220(51)90084-9"},{"key":"e_1_2_7_16_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0722.2005.00229.x"},{"key":"e_1_2_7_17_1","doi-asserted-by":"publisher","DOI":"10.1093\/aje\/kwi187"},{"key":"e_1_2_7_18_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.2001.72.11.1624"},{"key":"e_1_2_7_19_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-051X.1988.tb01563.x"},{"key":"e_1_2_7_20_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-051X.1990.tb01068.x"},{"key":"e_1_2_7_21_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.0303-6979.2004.00433.x"},{"key":"e_1_2_7_22_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-051X.2005.00713.x"},{"key":"e_1_2_7_23_1","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-051X.29.s-3.2.x"},{"key":"e_1_2_7_24_1","first-page":"508","volume-title":"Periodontal surgery: Access therapy","author":"Wennstr\u00f6m J","year":"1997"},{"key":"e_1_2_7_25_1","first-page":"3","volume-title":"Wound repair.
