Authors: Sharma Rinu , Bhochhibhoya A. , Acharya B , Rana SB , Sagtani RA 
Published: December 2019

Introduction: An accurate impression is the foundation of denture fabrication process thus a practitioner should be aware of the possibility of including errors during this procedure. Time spent in making a good impression will reduce the time required in adjusting the final prosthesis as well as make it more comfortable for the patient in accepting the prosthesis.
Materials and Methods: Maxillary arch final impressions made by undergraduate dental students on 106 edentulous patients were evaluated. The impressions were assessed on the basis of criteria’s like errors on mixing, flow, tray positioning, presence of voids, creases/irregularities, exposure of tissue stops and extension at posterior border. The data’s collected were analyzed for the frequency of occurrence and distribution of each type of errors.
Results: It was found that 97.2% of students performed at least one detectable error during making of maxillary arch final impression. The number of errors made by students ranged from single to as much as seven errors in one impression. The most common error was lack of exposure of all tissue stops followed by presence of voids and creases/irregularities on impression surface.
Conclusion: There is high possibility of including errors while making maxillary arch final impression by undergraduate dental students. The study highlights the need to explore novel techniques of clinical demonstrations and teaching important concepts to learning students. The inclusion of more pre-clinical exercises in undergraduate curriculum relating to manipulation of dental materials may improve skills of students in making accurate edentulous impressions.

Authors: Basnet Bishal Babu 
Published: December 2019

Introduction: Facial proportion and dental proportions are matters of interest for dental professionals to craft a beautiful smile. In facial analyses, the role of different proportions cannot be overlooked when planning dento facial treatment. This study aims to determine the different facial proportions; smile index, lower smile index, nose width to outer inter commissural width, intercanine width to outerinter commissural width, nose width to intercanine width and outer intercommissural width to lower facial height in esthetically pleasing smile (ES) and esthetically unpleasing smile (US) groups.
Materials and methods: The frontal smiling photographs (N=152, 74 pleasing and 78 unpleasing smile) were gathered and different linear measurements were carried out using digital ruler. The facial proportions were derived and comparisons were made amongst groups and differences were examined in comparison to standard accepted proportion (such as Golden proportion).
Results: Average smile index of ES (5.899±1.201) was lower than that of US group (6.421±1.675).The golden proportion was not valid for smile indices in each group. Mean nose width to intercanine width ratio significantly differed in ES and US. The outer inter commissural width to lower facial height was not statistically significantly different from 1:1 ratio.
Conclusion: Most facial proportions in pleasing and unpleasing smiles showed no difference. The outer intercommissural width to lower facial height was found in 1:1 proportion current study with possible utilization in determining vertical dimension of occlusion.

New technologies at the Venice Biennials the beginning of the XXI century
Authors: Олег СИДОР  
Published: December 2019

The article focuses on the analysis of selected examples of the use of new technologies in the artworks presented in the Venice Biennale during 2001–2017. Going along with time, national projects at the Biennale are forced at least to take the new technologies into account if not to build their presentations based entirely on them. Technology is no longer concealed or hidden: it is a matter of bravado. It is used to mark the vague profile of the “new poetics,” the exact sense of which is still unclear and incomprehensible to us. It has been pointed that turning to the new technologies does not always produce striking artworks, full of attractive images (i.e. Breaking the Waves by Lars von Trier).

Authors: Capato Tamine T.C. , de Vries Nienke M. , IntHout Joanna , Barbosa Egberto R. , Nonnekes Jorik , Bloem Bastiaan R. 
Published: December 2019

Background: Balance impairment in Parkinson’s disease (PD) improves only partially with dopaminergic medication. Therefore, non-pharmacological interventions such as physiotherapy are important elements in clinical management. External cues are often applied to improve gait, but their effects on balance control are unclear. Objective/Methods: We performed a prospective, single-blind, randomized clinical trial to study the effectiveness of balance training with and without rhythmical auditory cues. We screened 201 volunteers by telephone; 154 were assigned randomly into three groups: (1) multimodal balance training supported by rhythmical auditory stimuli ( n = 56) (RAS-supported multimodal balance training); (2) regular multimodal balance training without rhythmical auditory stimuli ( n = 50); and (3) control intervention involving a general education program ( n = 48). Training was performed for 5 weeks, two times/week. Linear mixed models were used for all outcomes. Primary outcome was the Mini-BESTest (MBEST) score immediately after the training period. Assessments were performed by a single, blinded assessor at baseline, immediately post intervention, and after one and 6-months follow-up. Results: Immediately post intervention, RAS-supported multimodal balance training was more effective than regular multimodal balance training on MBEST (difference 3.5 (95% Confidence Interval (CI) 2.2; 4.8)), p < 0.001). Patients allocated to both active interventions improved compared to controls (MBEST estimated mean difference versus controls 6.6 (CI 5.2; 8.0), p < 0.001 for RAS-supported multimodal balance training; and 3.0 (CI 2.7; 5.3), p < 0.001 for regular multimodal balance training). Improvements were retained at one-month follow-up for both active interventions, but only the RAS-supported multimodal balance training group maintained its improvement at 6 months. Conclusion: Both RAS-supported multimodal balance training and regular multimodal balance training improve balance, but RAS-supported multimodal balance training–adding rhythmical auditory cues to regular multimodal balance training–has greater and more sustained effects.

Background: Speech disorders are among the most common adverse effects after subthalamic nucleus deep brain stimulation (STN-DBS) in Parkinson’s disease (PD) patients. However, longitudinal speech changes after STN-DBS are not fully understood. Objective: We performed a two-year prospective study on PD patients who underwent STN-DBS and analyzed changes in speech function to clarify factors predicting for speech deterioration. Methods: Twenty-five PD patients were assessed before and up to two years after STN implantation. Speech function was evaluated in the on-stimulation condition and 30 min after stimulation cessation using auditory-perceptual assessment. Patients who experienced overall worsening in speech intelligibility or naturalness ≥1 point during follow-up were classified into a deteriorated group ( n = 16), with the remaining subjects being classified into a stable group ( n = 9). Cognitive and motor functions were also assessed. Results: The stable group had significantly better values of low volume, monoloudness, and asthenic voice subscores of the auditory-perceptual assessment in the on-stimulation condition compared with the off-stimulation condition. Imprecise consonants, excess loudness variation, and strained voice subscores were improved via cessation of stimulation in both groups. Before surgery, the deteriorated group had significantly lower scores in the Stroop Color-Word Test and Digit Span compared to the stable group. Conclusions: During follow-up, some subscores showed significant worsening in the on-stimulation condition in both groups. However, beneficial effects of STN-DBS on speech appeared to counterbalance negative effects of STN-DBS on speech function only in the stable group. Worse cognitive function may be a potential predictor for speech deterioration after STN-DBS in PD patients.
