There are numerous causes. The aim of this study was to investigate the influence of fixed orthodontic appliances on the occurrence of halitosis. 55 patients in an orthodontic practice were monitored at three points in time after application of orthodontic appliance (T1: immediately after application, T2: 4 weeks after application, T3: 3 months after application). Monitoring included patient self-evaluation, plaque index, tongue coating index and organoleptic measurement. The subjective parameters taste, dry mouth and breath odor did not show statistical differences. However, with the presence of fixed orthodontic appliances, confidence when performing dental hygiene decreased statistically significantly (p = 0.003). Additionally, the tongue coating index showed a statistically significant difference between T1 and T2 (p = 0.012) as well as T1 and T3 (p ⟩ 0.001). Analogous results were found for organoleptic measurement (T1 and T2 [p = 0.002]; T1 and T3 [p ⟨ 0.001]) and plaque index (T1 and T2/ T3 [p ⟨ 0.001]). Fixed orthodontic appliances lead to a statistically significant increase of the plaque and tongue coating indices. A statistically significant increase was also observed with organoleptic measurement scores. The suspected positive correlation between halitosis and fixed orthodontic appliances was confirmed. Halitosis can be an important indicator of oral health during orthodontic treatment and can serve as a motivating factor for adequate patient oral health care maintenance. </p>","PeriodicalId":74765,"journal":{"name":"Schweizer Monatsschrift fur Zahnmedizin = Revue mensuelle suisse d'odonto-stomatologie = Rivista mensile svizzera di odontologia e stomatologia","volume":"123 12","pages":"1064-75"},"PeriodicalIF":0.0,"publicationDate":"2013-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"32140626","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Group AB received amoxicillin and metronidazole three times a day for 7 days. Group PDT received two applications of PDT on the day of SRP as well as at follow-up after 7 days. The following clinical parameters were measured at baseline and 3 months after therapy: plaque index (PLI), bleeding on probing (BOP), probing depth (PD), gingival recession (GR), and clinical attachment level (CAL). After 3 months, PD was significantly reduced in both groups (from 5.0±0.8 mm to 3.2±0.4 mm with AB, and 5.1±0.5 mm to 4.0±0.8 mm with PDT; both p<0.001), while AB revealed significantly lower values compared to PDT (p = 0.001).

Various invasive treatment methods (decompression, marsupialisation, enucleation, enucleation with adjunctive therapy such as scraping out of the bone cavity, Carnoy's solution or cryotherapy, mandibular resection) have been described for the treatment of KCOT. There is no common opinion on the best kind of treatment. Most of the articles in the literature report on a follow-up period of 5-7 years, but relapses have been described even after longer periods of time. This article presents 3 cases with late relapses that were treated at the University of Zurich, Center of Dental Medicine, Clinic of Cranio-Maxillofacial Surgery and Clinic for Oral Surgery. At the time of the initial diagnosis, the patients were 19, 24.5 and 36 years old. In all 3 patients the KCOT was localized in the angulus/ramus mandibula and an impacted wisdom tooth was present in the affected area. Case no. 1 was treated solely by marsupialisation of the KCOT. In cases no. 2 and 3, the cystic lesion was first marsupialised and later treated by enucleation and application of Carnoy's solution. In case no. 1, a relapse developed 13.5 years after the first operation. In case no. 2, relapses occurred 9, 28 and 31 years after the first operation. In case no. 3, a first relapse appeared 9 years and a second one 18 years after the first operation.</p><p><strong>Conclusion: </strong>Patients with a KCOT require lifelong aftercare because relapses of KCOTs can arise even after 10 or more years.

The purpose of this investigation was to examine perceived stressors and three dimensions of burnout among dental residents enrolled in the University of Bern, Switzerland. Thirty-six residents enrolled in five specialty programmes were administered the Graduate Dental Environment Stress (GDES30) questionnaire and the Maslach Burnout Inventory (MBI). Individual stress items and overall GDES30 scores were used to quantify perceived stress. To measure burnout, proportions of burnout \"cases\" and MBI subscale scores were computed in the domains of emotional exhaustion (EE), depersonalization (DP) and reduced personal accomplishment (PA). Analyses relied on descriptive and bi-variate methods. The mean GDES30 score was 2.1 (SD = 0.4). \"Lack of leisure time\", \"meeting the research requirement of the programme\" and \"completing graduation requirements\" emerged as the top three stressors. Thirty-six percent of respondents were burnout \"cases\" on the PA scale, while this proportion was 17% for EE and 8% for DP. Both stress and burnout levels increased according to year of study, whereas younger residents and females had consistently higher stress and burnout scores compared to older ones and males.
