The future definitely belongs to the digital technologies because they offer a reliable, predictable and highly esthetic manner of treatment. The aim of the present study is to investigate the dental technicians' readiness to manufacture dental prostheses using digital technologies. Material and methods: A total of 159 respondents - practicing dental technicians and students - were surveyed using an on-line survey. The survey was conducted via a in the social network platform. Results were processed with SPSS v. 20. using variational, comparative and correlation analyzeses. Results: Over 50% of the respondents people have indicated that they use different types of digital technologies in their practice, the main reason being that the construction time is shortened and that the accuracy is improved (85.20%). There has been a correlation between the length work experience and the use of new technologies (p<0.05), with younger specialists being the ones who primarily use modern technology. Young specialists are willing to invest in the purchase of modern equipment and to attend additional courses on working with it. Conclusions: Despite the variety of methods for recreating the prosthetic field when manufacturing prosthetic constructions, a trend towards full digitalization of the process is observed. The results from the conducted analyses show that digitalization is being increasingly used by young specialists (CAD planning and software application – 78.40%), who prefer it because it increases accuracy and shortens production time (85.40%).","PeriodicalId":303832,"journal":{"name":"Scripta Scientifica Medicinae Dentalis","volume":"519 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123121800","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}

The main finding is unilateral or bilateral benign enlargement of masseter muscles, which results in a pronounced contour of the face and/or in the angle of the lower jaw, as well as the occurrence of asymmetry in unilateral hypertrophy. Surgical resection of the masseter was a conventional method in the past for asymmetric edema treatment above the shoulder and the angle of the lower jaw, after unsuccessful altering of the vertical dimension, dental aligners, tranquilizers, etc. An effective alternative is injecting locally small doses of botulin toxin type A in the masseter. The toxin prevents the release of acetylcholine, causing presynaptic neuromuscular blockage. This way the muscles could be selectively weakened and after local paralysis muscle atrophy is observed. This technique ensures predictable result and it is an alternative conservative method for treating this type facial asymmetry. Another conservative way for treating MH is radio frequency electrocoagulation. The presence of MH after dental treatment requires specialized intervention of specialists and application of contemporary non-invasive interventions with predictable results.","PeriodicalId":303832,"journal":{"name":"Scripta Scientifica Medicinae Dentalis","volume":"120 51","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120826217","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}

Factors like light condition, timeframe, age, sex, clothing, visual perception, redistribution of enamel masses, shine, transparency, opacity, and color of the gingiva make it harder to determine the right color of the teeth. Contemporary dentistry uses different methods and mechanisms, which can ease the work of the dentists. The uses of spectrophotometers, colorimeters, and digital images are useful instruments when analyzing the colors. These instruments are useful methods for analyzing the colors for direct and indirect restorations, procedures before and after teeth whitening, communication with indirect restorations, recreation and shade checking, as well as quality control of color recreation. In articles the authors recommend when available to combine the visual method as well as the instrumental method of color determination, because they complement each other and lead to predictable results.","PeriodicalId":303832,"journal":{"name":"Scripta Scientifica Medicinae Dentalis","volume":"77 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131830134","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}

The aim of this article is to assess caries prevalence in a group of children treated under general anesthesia. Subject of monitoring of the clinical research are 396 children divided into three age groups: up to 5 years, between 6 and 12 years and over 12 years. The dental status was examined and registered according to WHO using the dmft/DMFT index. This index is higher in children in the group of children under 5 years (16.59±3.46) compared to 5-12 year old patients (10.66±1.79) and patients over 12 (9.96±1.74). There is a statistically significant difference in the incidence of dental caries between the first and second study groups, as between the first and third groups. The probable cause is the large number of children with early childhood caries (ECC) whose dmft index is the highest. High index values are mostly because of untreated complicated carious lesions. The number of obturated(f) and premature extracted(m) teeth is negligible. This result demonstrates more active cariogenic environment in children treated under general anesthesia. It is probably due to the reduced ability to create proper oral hygiene skills, due to physical disorders or the pain of complicated caries in children with early childhood caries and the need of prophylaxis is obvious.","PeriodicalId":303832,"journal":{"name":"Scripta Scientifica Medicinae Dentalis","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129977860","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}

The first permanent molar eruption is related to the onset of significant changes in the developing occlusion. Although this tooth is seen as the `key to occlusion` its value as an anchorage is debatable. The aim of the article is to study the correct position of the upper first molars in the two planes of space - the sagittal and transverse planes. In this article the position of the first upper molar is examined with the aid of diagnostic records, such as study cast, orthopantomogram (OPG), and lateral cephalometrics. A literature review includes Bulgarian and foreigner authors. Angle, who in 1899 referred to the maxillary first permanent molars as the `key to occlusion`, was the first to mention their importance within the dentition. According to Angle, the line passing through the middle of the mesiobuccal cusp of the upper first molar coincides with the line passing through the buccal groove of the lower first molar. After Angle, other authors have discussed the position of upper molars from different point of view, such as their relation or position in the maxilla, anteroposterior axial inclination and rotation. As indicated by Lamons and Holmes molar rotations commonly exist in Class II malocclusions. The molars are usually rotated around an axis lingual to their central fossae. In an ideal occlusion the buccal surfaces of the upper first molars are usually parallel to each other. On the OPG Kurol and Bjerklin measured the axial mesial inclination of upper first molar. The tipping of the molars is measured by the angle formed between the tangent line to the mesial surfaces of the root and crown and the line through the lower margins of the left and right orbits. According to Sassouni, the mesial contour of upper first molar should to lie on the 4th arc - the temporal arc. If the molar is anterior to this arc, a treatment with distalization could be initiated. The temporal arcnasion distance measured on the radius is equal to the distance from point ANS to the upper first molar. The position of the upper first molar varies with the position of the upper central incisors. The basic hypothesis is that if the upper first molar has a fixed position in the face, any increase in the total upper dental arch length will be transferred to the incisor area. Any change in the anteroposterior position of the upper first molar could influence the position of the mandibular- leading to Class II malocclusion. Ricketts pointed out that the average distance from the pterygoid vertical (PTV) to the distal surface of upper first molar is the sum of the age of the patient + 3mm, in a growing patient. This diagnostic method can help the orthodontist to decide whether to extract teeth or to distalize the molars. Any loss of space in the arch is a justification for early orthodontic treatment.
