The participants' age ranged between 18 and 71 years, with the median age of 45 (34\u201357) years. Forty-seven percent of the participants were females. The validity and reliability of the Croatian OHIP version were tested. The impact of gingivitis and periodontitis on QoL was assessed. Changes in QoL induced by nonsurgical periodontal therapy in 20 patients with periodontitis were analyzed.<\/jats:p><jats:p>\n          Statistical Analysis\u2003Categorical data were presented by absolute and relative frequencies. The normality of the distribution of continuous variables was tested by the Shapiro\u2013Wilk test. Continuous data were described by the median and the limits of the interquartile range (IQR). Differences in continuous variables between two independent groups were tested with the Mann\u2013Whitney U test, and between three groups with the Kruskal\u2013Wallis test (post hoc Conover). The Wilcoxon signed-rank test was used to examine the differences in the total score before and after therapy. All p values were two-sided. The level of significance was set at alpha of 0.05.<\/jats:p><jats:p>\n          Results\u2003The analysis detected a single-factor structure that explained for the 56.9% of the variance. Cronbach's alpha value was 0.937, which indicated an excellent internal consistency. Overall OHIP score reported a strong correlation with the subjective estimate of periodontal problems (Rho\u2009=\u20090.92; p\u2009&lt;\u20090.001). Test\u2013retest reliability was high (r\u2009=\u20090.984; p\u2009&lt;\u20090.001). The periodontitis group had the highest OHIP score (28 [23\u201334]), followed by the gingivitis group (14 [12\u201320]) and the periodontally healthy group (9 [5\u201311]; p\u2009&lt;\u20090.001). Nonsurgical periodontal therapy significantly improved the QoL in those with periodontitis (p\u2009&lt;\u20090.001).<\/jats:p><jats:p>\n          Conclusion\u2003The condition-specific Croatian version of the OHIP instrument can be considered adequate to measure the impact of periodontal diseases on oral health\u2013related QoL. Periodontal diseases, especially periodontitis, have a negative effect on the patient's QoL. Nonsurgical periodontal treatment can improve patients' QoL.<\/jats:p>","DOI":"10.1055\/s-0044-1785534","type":"journal-article","created":{"date-parts":[[2024,8,5]],"date-time":"2024-08-05T23:04:55Z","timestamp":1722899095000},"page":"1172-1178","source":"Crossref","is-referenced-by-count":6,"title":["Impact of Periodontal Diseases on Oral Health-Related Quality of Life: A Study with a Condition-Specific Questionnaire in Croatian Population"],"prefix":"10.1055","volume":"18","author":[{"given":"Aleksandar","family":"Pupovac","sequence":"additional","affiliation":[{"name":"Department of Periodontology, Faculty of Dental Medicine, University of Rijeka, Rijeka, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Davor","family":"Kui\u0161","sequence":"additional","affiliation":[{"name":"Department of Periodontology, Faculty of Dental Medicine, University of Rijeka, Rijeka, Croatia"},{"name":"Department of Periodontology, Clinic of Dental Medicine, Clinical Hospital Center Rijeka, Rijeka, Croatia"},{"name":"Department of Dental Medicine, Faculty of Dental Medicine and Health, University of Osijek, Osijek, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ivana","family":"Mi\u0161kovi\u0107","sequence":"additional","affiliation":[{"name":"Department of Periodontology, Clinic of Dental Medicine, Clinical Hospital Center Rijeka, Rijeka, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jelena","family":"Prpi\u0107","sequence":"additional","affiliation":[{"name":"Department of Periodontology, Faculty of Dental Medicine, University of Rijeka, Rijeka, Croatia"},{"name":"Department of Periodontology, Clinic of Dental Medicine, Clinical Hospital Center Rijeka, Rijeka, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2024,8,5]]},"reference":[{"issue":"10","key":"ref1","doi-asserted-by":"crossref","first-page":"1403","DOI":"10.1016\/0277-9536(95)00112-K","article-title":"The World Health Organization Quality of Life assessment (WHOQOL): position paper from the World Health Organization","volume":"41","year":"1995","journal-title":"Soc Sci Med"},{"issue":"06","key":"ref2","doi-asserted-by":"crossref","first-page":"358","DOI":"10.1111\/j.1834-7819.1994.tb03106.x","article-title":"Social impact of oral conditions among older adults","volume":"39","author":"G D Slade","year":"1994","journal-title":"Aust Dent J"},{"issue":"04","key":"ref3","doi-asserted-by":"crossref","first-page":"284","DOI":"10.1111\/j.1600-0528.1997.tb00941.x","article-title":"Derivation and validation of a short-form Oral Health Impact Profile","volume":"25","author":"G D Slade","year":"1997","journal-title":"Community Dent Oral Epidemiol"},{"issue":"06","key":"ref4","doi-asserted-by":"crossref","first-page":"454","DOI":"10.1111\/j.1600-051X.2004.00498.x","article-title":"Impact of oral health on the life quality of periodontal patients","volume":"31","author":"I Needleman","year":"2004","journal-title":"J Clin Periodontol"},{"issue":"04","key":"ref5","doi-asserted-by":"crossref","first-page":"333","DOI":"10.1111\/jcpe.12517","article-title":"Are periodontal diseases really silent?
