Free-running and Q-switched infrared Er:YAG laser radiations, ultrasonic ball tip, and classical hand piece drilling machine were compared in the case of hard dental tissues preparation. For the radiation delivery, a special waveguide transfer system was used. Light-cured, high viscosity flowable HDR microfilled hybrid composite material was used for restorations. The longitudinal sections of extracted human teeth with filling material were compared from the point of view of prepared cavity shape and filling material in scanning electron microscope.

Mineral Trioxide Aggregate (MTA) was introduced into dentistry as a root-end filling material. Several researches and investigations were done on its properties and uses. In this review, the composition, properties and indications of MTA are mentioned, along with the techniques for its use in various clinical situations like pulp capping, internal and external root resorptions, lateral and strip perforations, furcal perforation, apexification, root-end filling and root-canal filling. A case report of repairing furcal perforation using MTA is also documented.

Overdenture -Teeth or Implants Evaluation

P. Radina, M. Seydlová, T. Dostálová, O. Simerská, J. Zvárová

Čes. stomatol. Prakt. zub. lék. (Czech Dental Journal) 2007; 107(3): 48-57  

The study compares two types of prosthodontic treatment - overdentures supported own patients' teeth with ball attachments or implants. 35 patients (from 1 to 5 years recall) were evaluated. Subjectively or objectively there was found no significant difference between both groups.

Cement-retained and Screw-retained Implant-supported Prostheses in Treatment of Dental Arch Defects

Fixed dentures could be connected to implants by abutments, through tightening of small screws or cementation. Another option is the direct screw connection without abutments. Dentist should decide which method of connection is appropriate for a given situation. Knowledge of advantages, disadvantages and limitations of methods above is important for treatment plan and design of stable and functional denture.

Oral Hygiene and Orthodontia: What Kind of Approach?

R. Tichá, J. Tichý, H. Böhmová

Čes. stomatol. Prakt. zub. lék. (Czech Dental Journal) 2007; 107(3): 57-61  

The objective was to determine to what extent the attachment of fixed orthodontic appliance enables oral hygiene in the patient and to summarize possible risks ensuing from insufficient oral hygiene and their impact on hard and soft tissues of oral cavity as well as methods and hygienic agents useful for the patient. The patients were followed up as far as the oral hygiene and gingival bleeding were concerned using modified PBI and API indices, respectively and the Ortho-plaque index. Higher gingival bleeding was associated with attachment of the fixed appliance in all appliance and there was also a higher accumulation of dental plaque on the contact...

Comparison of Preparative Methods Used for Deciduous Teeth

A. Šváchová, V. Merglová, J. Beneš, J. Kasl

Čes. stomatol. Prakt. zub. lék. (Czech Dental Journal) 2007; 107(3): 62-69  

The aim of the pilot study was to compare preparation methods most frequently used in the conservative treatment of deciduous teeth caries. The experiment was performed ex vivo in extracted carious deciduous molars. Hand excavation, preparation with burs and chemomechanical caries removal were compared. Results of these techniques were analysed using the caries detector dye, light and digital scanning electron microscopy. The time of each preparation was measured.

Effect of Plain and Fluoridated Milk on Root Surface Caries in Vitro

The caries-protective effect of milk and fluoridated milk on enamel has been reported; however, few data are available concerning the role of milk and/or fluoridated milk on root surfaces. The aim of this study was to compare the effect of plain and fluoridated milk on root surface caries. Artificial root surface lesions were created, sectioned and analysed using polarized light microscopy (PLM) and microradiography (MRG). The sections were covered with acid - resistant varnish except of the original surface and assigned to a treatment group. The samples were immersed in 2% plain milk or fluoridated milk for 40 hours and re-evaluated. Changes were...

Tooth Pain and Dentine Sensitivity

E. Gojišová, M. Kukletová

Čes. stomatol. Prakt. zub. lék. (Czech Dental Journal) 2007; 107(3): 77-80  

Postoperative sensitivity is considered to be one of the main problem associated with adhesive technology treatment approach. Pain is considered to be a sign of an initial or continuous tissues' integrity disorder caused by harm stimulus. This unpleasant sign can be easily avoided by respecting the proper working procedures. The autor in her presentation focuses on the Brännstreom's pain theory. She explains its basics and presents the current aspects of treating the prepared dental tissue.
