Periodontal status and chronic obstructive pulmonary disease (COPD) – review of literature
Get PDFIntroduction. recently important associations between status of oral cavity and systemic diseases, one of which is chronic obstructive pulmonary disease, have been shown. Aim of the study. presentation of oral cavity status especially periodontal status in chronic obstructive pulmonary disease patients. Conclusions. chronic obstructive pulmonary disease patients indicate huge stomatological treatment needs
Implant based versus endodontic treatment concepts for anterior teeth
Get PDFIntroduction. Patients expect not only a fully functional restoration, but also an aesthetically pleasing and a long-lasting solution. Especially in the anterior region, aesthetics plays a vital role in treatment. Therefore, a practitioner needs to make a considerate choice between any treatment modality. Aim of the study. The aim of this paper is to present and compare methods of treating the anterior teeth in the aesthetic area, especially to compare root canal treatment (RCT) as opposed to implant-supported crowns (ISC) as far as their effectiveness, longevity and possible complications are concerned. Material and methods. PubMed and Medline were queried for all studies that compared non surgical root canal therapy and restoration with the extraction of teeth and placement of a dental implant. The full text of 58 articles related to the studied subject were analysed. Results. The effectiveness of implant and endodontic therapy is similar only in the first 6 years after treatment is completed. Over time a significant decrease in survival rates is observed for endodontically treated teeth, while for implants this fall is markedly lower. Conclusions. 1. A dentist should present to a patient both methods, their advantages, disadvantages and risks. 2. If RCT is risky due to root canal anatomy, especially in multi-rooted teeth, the implant option should be considered. The expected aesthetic effects should be considered, especially in the anterior area. Implant insertion does not always give a favourable and expected aesthetic result if this is not preceded by gingival and bony tissue preparation. The bony and soft tissue quality should be considered. Any bone density abnormalities or bone deficits seen on radiograms should help a dentist decide on RCT procedures or bone augmentation. 3. Properly done implanto-prosthetics preceded by a detailed analysis of the underlying tissues, of radiograms, and of diagnostic models should result in restoring the anatomical and physiological function of the lost tooth. 4. The decision on RCT or implant treatment should be taken following consultation from specialists in both these modalities and an assessment of the restoration survival time for both methods
Oral surgery application of Er:YAG laser
Get PDFThe laser beam is an alternative technique to traditional surgery applicable in many oral surgery cases. It enables to avoid suturing and thanks to decontamination features promotes healing process. The authors presented advantages and disadvantages of laser Er:Yag Kavo KEY 3, establishing the indications as well as working parameters in specific ceses. The conclusion of the research is that histopathologic evaluation is possible only in tissue probe larger than 3 squere mm. The photographs of 12 different cases shows the variety of possible laser Er:Yag application
Evaluation of occlusal contacts in patients with single tooth loss – preliminary report
Get PDFAim of the study. The aim of the study was to evaluate the distribution of the occlusal contacts in patients with single tooth loss in one or both tooth arches as compared to healthy patients with full dentition. Material and methods. The study was performed in a group of 30 patients aged 24–40, both male and female, who needed prosthetic treatment because of single tooth loss in one or both tooth arches. The control group consisted of 30 healthy patients, aged 21–37, with complete dentition. In both groups temporomandibular disorders were excluded. The evaluation of occlusal contacts distribution was carried out on the basis of the study of occlusion in the centric intercuspation position by means of T-scan II device (Tekscan Inc). Two functions of the relevant software were used: the first being the percentage distribution of the occlusal contacts on the left and right side of tooth arches. The second parameter under analysis was the model function of the tooth arch in 3D, which was used to evaluate the level of occlusal forces in relation to the colour coded scale calibrated for a specific software. The study results were statistically analysed by means of â€oStatistica” software package. Results. The mean difference quantities in group I (with single tooth loss) were 2.5 times higher than those in the control group. The above results differ in a statistically significant way as the analysis with the use of U Mann Whitney Test pointed out that â€op” is smaller than 0.05. The comparison of the two mean quantities indicates a meaningful influence of single tooth loss or clinical crowns damages on the stability and symmetry loss of the occlusal contacts balance. The analysis of the dental arch function (occlusal forces) indicates much higher values of the occlusal contacts marked in red for group I as compared with group II (the control group), which on the basis of the colour scale is to be interpreted as maximal occlusal forces. Conclusion. Single tooth loss has a significant impact on the disbalance distribution of occlusal contacts as well as on the value of masticatory forces
Selected dental disorders in patients with complete unilateral cleft of the primary and secondary palate
Get PDFIntroduction. The most common malformations associated with cleft lip and palate are dental abnormalities. Multifactorial etiology and the time of the formation of cleft palate and start building the dental lamina may be the cause of coexistence cleft defects and dental disorders. Aim of the study. Evaluation of the frequency and type of dental disorders in patients with complete unilateral cleft of the primary and secondary have been the subject of the research. Material and methods. The material consisted of panoramic films of 70 children (31girls, 39 boys) aged 8–11 years with a complete unilateral cleft of the primary and secondary. The radiographic evaluation are: dental status, number of teeth, and their construction. Results. In the group of 70 children were found to have abnormalities in the number and morphology of the teeth in a total of 60 patients (29 girls, 31 boys). The most commonly observed disorder was hypodontia (66.4%) found in 44 patients. Missing teeth (89.8%), were mainly found in upper jaw. In 67.7% hypodontia was on the incisors side located in the vicinity of cleft. There were also lack of upper premolars (29%) and central incisors (3.3%). Hyperdontia occurred in 9.6% and concerned maxillary lateral incisors on the cleft side. Another observed disorder was atypical tooth structure (24%) on the lateral incisors in the upper jaw. Conclusions. In patients with complete unilateral cleft palate primary and secondary, dental disorders were most frequently observed in the vicinity of cleft. The main dental disorder was hypodontia
