Survival of retained permanent canines after autotransplantation: A retrospective cohort study.

INTRODUCTION: After third molars, canines are the teeth most commonly affected by displacement and impaction. Although orthodontic surgical treatment represents the standard method for realignment of canines, autotransplantation (autoTX) functions as the second-line therapy if orthodontic alignment does not succeed in treating impaction and severe displacement. This retrospective cohort study aimed to identify clinical predictors for postoperative survival and endodontic treatment needs after autoTX of severely displaced and impacted canines. METHODS: The study cohort comprised patients who received canine autoTX in a single surgical center between 2006 and 2018. Canines with severe displacement and retention were surgically treated using a standardized protocol. Statistical analysis of survival probability was performed with the Kaplan-Meier method, and bivariate data were analyzed using logistic regression and the Pearson chi-square test. Nonparametric continuous variables were analyzed using the Mann-Whitney U test. RESULTS: Data from 319 patients with 378 canine grafts were available for analysis after a mean follow-up of 54.7 ± 36.5 months on the patient level (range, 0.3-181.8 months). With 25 lost autotransplants, the cumulative survival rate was 93.4%. Patient age at surgery, the state of the apical foramen, endodontic treatment need, and persistence of deciduous teeth at the implantation site had a significant negative impact on autotransplant survival (P <0.05). Endodontic treatment need was significantly related to the patient's age at surgery, the state of the apical foramen, and preoperative orthodontic traction (P <0.05). Thus, these independent variables were identified as clinical predictors for the survival of both the autotransplant and the dental pulp. Gender, ischemia time, postoperative ankylosis, or site of autoTX did not influence any of the outcome variables. CONCLUSIONS: The high survival rates of autotransplanted permanent canines make this treatment a promising option, especially in patients with severe tooth displacement, in which orthodontic treatment alone cannot provide predictable alignment, irrespective of the patient's age. Interpreting age and preoperative orthodontic traction as delaying the onset of autoTX and state of apex, time-dependent aspects seem to be of great importance for postoperative complications leading to endodontic treatment or graft loss. Therefore, early implementation of autoTX as a treatment modality for impacted, severely displaced, and vain exposed canines in daily surgical practice should be encouraged.

Changes in esthetic standards since 1940.

INTRODUCTION: The goals of this study were to investigate differences between the most popular female and male faces, past and present, and to determine whether they had changed over time and, if so, to what extent. METHODS: Internet film databases were searched for photographs of men and women who were considered attractive between 1940 and 2008. Images meeting defined inclusion criteria were compared. Measurements were taken on a minimum of 20 images per sex per decade. Intersex facial differences were grouped by decades, and we examined whether these differences remained stable or whether and how they changed over time. RESULTS: The women had fuller and more protrusive lip profiles than did the men, particularly during the first decade of the 21st century. Significant sex-specific developments were noted over time with respect to chin lengths, frontonasal angles, and total face angles. The men had decreases in chin size and length, but a small opposite trend was observed in the women's faces. During the observation period, female and male faces considered highly attractive became slightly more similar in terms of chin position and size. CONCLUSIONS: Notions of facial attractiveness might be influenced by developments in society.

[Poverty and deficits in basis social supplies among inpatient psychiatric patients]. / Armut und soziale Unterversorgung bei stationär behandelten psychisch Kranken.

OBJECTIVE: People with psychiatric diseases are often afflicted by processes of social disintegration and social problems are of great importance for the treatment of the mentally ill. METHODS: Two departments of psychiatry and psychotherapy with obligatory service for their area - one in an inner city area of a large town with disadvantageous social structure, one in a small town with more favourable economic data - collected data during a two-months-period in 1998 according to the social situation of their patients. RESULTS: 38,0 % resp. 31,9 % of the patients were living under conditions of poverty; 12,2 % resp. 11,5 % had acute housing problems, only 17,3 % resp. 31,7 % had some kind of payed occupation. Poverty was defined either as being dependent on public assistance or having an income below 50 % of the average. Patients with schizophrenic psychosis and patients with substance abuse related disorders formed in both departments the main groups and were at the same time those with the lowest income. Patients with substance abuse, mainly alcoholics, were more afflicted by social disintegration in the inner city area than in the small town sample. Concerning schizophrenic disorders, regional differences were not as prominent. CONCLUSIONS: The high risk of poverty among the mentally ill has to be taken in account in the development of community services, hospital staff and social legislation.
