Visualization assessment (CBCT) was performed using Planmeca Promax 3D Mid, and bone density was examined using dual energy X-ray absorptiometry (densitometry, DXA). The final sample consisted of 16 patients deemed suitable for immediate implant placement and loading of permanent prosthesis on the mandible. The distal implants were stabilized using a customized structure made of Titanium Ti6-Al4-V using DMLM 3D printing technology with Concept Laser machines. Modeling of the contours of the jawbone at the planned surgical site was carried out using cone-beam computed tomography and the Mimics Medical 21 software (Materialize, Germany) for each patient. A total of 32 such devices were created.Results: Of these, 18 were used as the initial implant stability was less than 35 N/cm of torque in a few cases only. The implant survival rate was 100% after 18 months. This method of mandibular implant prosthetic treatment using a customized device for implant stabilization has been patented.Conclusion: Splinting of the compact walls of the mandible using a customized structure optimized stabilization of the Trefoil prosthetic construction on porous bone (type IV) following extraction of teeth and placement of implants. Clinical testing of the reported method confirmed its viability for dental rehabilitation of elderly patients and proved its ability to provide a good quality of life by creating stable implant prostheses with high functionality.","PeriodicalId":35508,"journal":{"name":"Stomatologija","volume":"23 3","pages":"69-74"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40314739","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}

Since dental radiography is used widely for diagnosis, treatment planning and patient education, it is important for dentists to understand the problems associated with the use of radiation and the methods of preventing them. The present study was designed to assess and compare the knowledge, attitude and practice of dental house surgeons and undergraduate students towards radiation safety and protection.Materials and methods: A cross sectional questionnaire based survey was conducted among 153 dental house surgeons and undergraduate students attending a dental teaching hospital.Results: On comparison of the house surgeons with undergraduate students, the present study found that the knowledge, attitude and practice of house surgeons were better than the undergraduate students regarding AERB guidelines, ALARA principles, position distance rule, personal monitoring devices, thickness of lead barrier and use of lead protection. Both the groups had similar high knowledge regarding the harmful effects of X-rays. However undergraduate students had better knowledge regarding radiation hazard symbol and made better use of personal monitoring devices. A greater number of house surgeons were found to have had formal training in radiation protection while undergraduate students were more willing to undergo further training.Conclusion: Dental students must be educated regarding radiation safety and protection before they commense work as independent practitioners for the protection of their patients, the environment and themselves.","PeriodicalId":35508,"journal":{"name":"Stomatologija","volume":"23 3","pages":"80-85"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40315663","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}

In addition, the etiopathogenesis, clinical and morphological features and differential diagnoses of PA are discussed, emphasizing the importance of knowledge about the characteristics of this tumor for a correct diagnosis.Case report: A 50-year-old woman presented with a nodular lesion of endophytic growth in the left cheek mucosa. The lesion was small and well-delimited and had a normal mucosa color and intact surface. An excisional biopsy of the lesion was performed, and the diagnosis was PA.Conclusion: Although the occurrence of PA in the minor salivary glands of the cheek mucosa is uncommon, the early establishment of a correct diagnosis and initiation of appropriate treatment are important because they permit effective management of the condition and improvement in the prognosis of patients.","PeriodicalId":35508,"journal":{"name":"Stomatologija","volume":"22 3","pages":"92-96"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"25563969","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 objective of this systematic review was to assess the influence of temporary filling material on dental cracks and fractures during endodontic treatment.Materials and methods: The literature was digitally searched for in vivo and in vitro studies using Pubmed, ScienceDirect and Wiley Online Library databases. A total of 38 potentially relevant records were identified in the literature search after duplicates were removed. After screening, full-text analysis of selected studies was done. Two reviewers independently selected the studies, extracted the data which was structured and summarized.Results: Five publications met the selection criteria. Ten temporary filling materials were evaluated in this review. The analysis demonstrated that non-eugenol chemically hardening temporary filling materials significantly increase filling and dental fractures and have the lowest fracture and tooth fracture resistance. Glass ionomer cements (GIC) presented the higher hermetic, tightness and fracture resistance features.Conclusions: A temporary filling material during endodontic treatment may influence dental cracks and fractures.

The aim of this work was to analyze monozygotic and dizygotic twins' mandibular asymmetry in sagittal direction using cephalometric data and to analyze its dependence of genetic and environmental factors.Material and methods: Study sample consisted of 80 dizygotic (DZ) and 80 monozygotic (MZ) twins of same sex. 3 cephalometric measurements were made to determine mandible asymmetry in sagittal direction. Indexes of mandibular asymmetry (IMA1, IMA2) were calculated. Data analysis was done using Microsoft Excel (2013). Genetic and environmental factors influencing mandible asymmetry was determined.Results: Mandibular dental asymmetry was bigger in monozygotic twins' group but the results were not statistically significant. Mandibular skeletal asymmetry was significantly bigger in dizygotic twins' group: IMA1(DZ)=3.05±1.94, IMA1(MZ)=1.92±1.05, p=0.005. IMA2(DZ)=3.12±2.04, IMA2(MZ)=1.88±1.04, p=0.004. Distance between distal borders of the ramus is mostly determined by genetic factors.Conclusions: 1. Mandibular skeletal asymmetry was significantly bigger in dizygotic twins' group. Mandibular dental asymmetry and symmetry did not differ in groups significantly. 2. Skeletal mandible's asymmetry is more determined by genetics than environmental factors, but lower molars' sagittal position is determined more by environment.","PeriodicalId":35508,"journal":{"name":"Stomatologija","volume":"22 2","pages":"54-57"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38308109","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}
