Klinikinis dentino silerio veiksmingumas esant padidėjusiam dantų šaknų jautrumui po periodonto chirurginio gydymo

Objective. The aim of this study was to evaluate the effectiveness of a commercially available light-cured, resin-based dentin sealer in the treatment of postoperative sensitivity of roots with gingival recession of different extent. Materials and methods. The study was a case control, randomized, blind design. A total of 62 patients with the presence of chronic periodontitis, who required periodontal surgery, participated in this study. All recipients underwent flap operation. After the periodontal surgery 641 teeth were selected for the study. The pain intensity was determined by using visual analogue scale (VAS). The extent of gingival recession was measured using William’s periodontal probe. After recording the initial baseline VAS scores, the patients were randomly divided into two groups according to the materials used in the study. The resin-based dentin sealer in the test group was applied following the manufacture’s recommendations. Water was used in the control (placebo) group. Hypersensitivity measurements on VAS were repeated 5 minutes, 7 and 30 days after the application of the materials. Results. It was observed that the efficacy of the desensitizing material differed from placebo. The dentin sealer effectively reduced the root sensitivity. The statistically significant (p<0.001) decrease in the intensity of root sensitivity after the application of materials was noted in test and control groups. However, the difference in the reduction of pain intensity between the groups was significant and remained such throughout the study period. The root sensitivity on the day 7 and 30 in both groups showed little change compared to the measurements made right after the application of the materials. No significant difference in measurements of pain intensity in the presence of different extent of gingival recession was noted in none of the groups. Conclusion. The results of the study showed that dentin sealer used provided quick and effective reductio

Xerostomia: clinic, etiology, diagnosis and treatment

The aim of this article is to review the problem of xerostomia considering its clinical, etiological, diagnostic and treatment features, basing on the today’s tutorials and scientific articles found in databases on the Internet. Recent epidemiologic data on the prevalence of xerostomia in different countries are introduced. There are analyzed the main aspects of clinical manifestations of xerostomia, according to the different etiology analyzed. The most common etiological factors causing xerostomia, especially the main three of them: radiation therapy, Sjögren’s syndrome, and drugs, are pointed out. The most popular and accepted clinical and laboratory assays for measuring and evaluating the function of salivary glands are represented. Attention is paid to xerostomia as substantiation of the separate diagnosis and its role in diagnosing other diseases. The concept of possible treatment modalities and prognosis are discussed. The main and most common problems concerning xerostomia are revealed

Microflora of the Oral Cavity in Patients with Xerostomia

Objective. The aim of this study was to evaluate the dependence of the condition of the microflora of the oral cavity on the etiology of xerostomia, patients’ sex, age, degree of hyposalivation, and duration of the sense of dryness. Material and Methods. A total of 64 patients with complaints of oral dryness referred to the Clinic of Oral and Dental Diseases, Hospital of Lithuanian University of Health Sciences, for consultation during the period from 2003 to 2005 were selected for the study. The etiological factors of xerostomia were as follows: radiotherapy (PRT) to the maxillofacial area, Sjögren’s syndrome (SS), and xerogenic medications, tricyclic antidepressants (TCAs). Results. There were 50 women and 14 men. Their mean age was 60.5±1.6 years. All the patients in the PRT group had high counts of Candida spp. as compared with percentages of patients in the TCA and SS groups (100% vs. 66.7% and 56.2%, P&lt;0.05). Patients’ age and sex in different etiology groups had no significant impact on the condition of their oral microflora. There were equal percentages of patients with deficient and normal salivation in the TCA group (44% in both the groups; P&lt;0.01). All the patients in the PRT group had pronounced hyposalivation (P&lt;0.002). A significantly greater percentage of patients with severely reduced salivation had high counts of Lactobacillus spp. (P&lt;0.01). Significantly greater percentages of patients with the clinical duration of xerostomia of up to 6 months had high counts of Lactobacillus spp. and Candida spp. colonies. Conclusions. In patients with xerostomia, the condition of the microflora of the oral cavity and impairment of major salivary gland function varied according to the etiology of the disease. The level of hyposalivation and the duration of xerostomia were found to have a significant impact on the microflora of the oral cavity
