Abstract

Introduction: At present, the researchers are targeted to improve and increase the biocompatibility of dental materials that are in direct contact with biological tissues. The biocompatibility of the dental materials that contact the tissues of the oral cavity present relevance for the patient, clinician, dental technician, and manufacturer.

Aim of the study: The aim of this study was represented by the comparative research regarding the comfort of the patients wearing removable partial prostheses with clasps made of wire and flexible polymers.

Material and Methods. Patients wearing partial dentures from Meliodent heat-cured acrylic resins with wipla wire clasps, flexible partial dentures made from Valplast and dentures with clasps of CuSil silicone rubber participated in this study. The research was performed on 3 groups, of 8 patients each, in which comfort levels (according to 5 criteria) were determined, after 6, 12, 18, respectively 24 months of the partial removable prostheses insertion in the oral cavity.

Results. Presence of decubitus lesions of the oral mucosa in the clasps areas was noticed mostly in the Valplast polyamide dentures (37.5%), existence of color changes at the base of prostheses and of clasps area appeared in 37.5% of the third group (CuSil PAD) patients, no patient included in the study presented allergic reactions and at the third and fourth recall, only 1 patient of all groups complained of unpleasant taste in the oral cavity.

Conclusion. The removable prosthetic restorations with clasps made of flexible polymers and CuSil gaskets of silicone rubber, although initially much more comfortable and therefore much better accepted by patients, after two years were no longer active, could not be activated and necessited technical restorations, compared to those made of wipla wire clasps, which were activated with pliers, or, in the case of fracture, were replaced by the technician in the dental laboratory.

Abstract

Introduction: The development and eruption of teeth should be followed by the dentist, which is why periodic check ups are required.

Aims of the study: This study aims to evaluate the knowledge of the mothers regarding the dental hygiene of the children and the importance of presenting them in the dental office, as well as the knowledge related to the prevention of dental caries.

Material and Methods: A questionnaire comprising 15 questions was developed and handed to 290 mothers in Tirgu Mures. The questions targeted the knowledge related to the dental hygiene of the child, and decay prevention.

The data obtained were processed electronically. 51.7% of the mothers stated that the visit to the dental office should be done every 6 months, and 58.6% opted for a first contact with the dentist at the age of 3 years. 98.2% of mothers consider dental prevention to be important or very important. 75% consider that the child’s hygiene must be done twice daily, and 89% said that they use the toothbrush in the child’s hygiene process. 68% of the mothers know the term of dental sealing, but only 20% resorted to this method of treatment.

Conclussions: The study demonstrates the urgent need to take the lack of interest and information of parents seriously and to develop programs primarily to inform and raise awareness of the population and then to apply different preventive methods.
