Changes in Oral Health Related Quality of Life (OHRQoL) and Satisfaction with Conventional Complete Dentures Among Elderly People.

Purpose: To assess the changes in oral health-related quality of life (OHRQoL) and satisfaction among older adults after receiving new complete dentures, and the association of age, gender, education, medical history, past prosthetic history (number of previous complete dentures and time since current complete dentures) and quality of existing complete dentures with patients' ratings of satisfaction with their complete dentures.

Materials And Methods: The study comprised 114 community-dwelling adults ≥ 65 year of age, all wearing complete dentures in both jaws. The sample was selected from four senior day centres.

Frequency and quality of root canal fillings in an adult Serbian population.

Introduction: Estimation of frequency and quality of root canal fillings is the way to evaluate endodontic treatment needs and success/failure rates of performed endodontic procedures.

Objective: The aim of this study was to determine the frequency and quality of root canal fillings and the frequency of apical periodontitis on endodontically treated teeth in a group of adult patients from Serbia.

Methods: In order to analyze the presence and quality of root canal fillings and the frequency of periapical radiolucencies on endodontically treated teeth, 3526 teeth were examined on orthopantomograms of 153 adult patients.

Prevalence and Clinical Effects of Certain Therapy Concepts among Partially Edentulous Serbian Elderly.

Purpose: This study was conducted to identify the prevalence of partially edentulous individuals in Serbia and to identify prosthodontic treatment used for their rehabilitation as well as to compare prosthodontic treatment concepts among Serbian elderly participants who answered closed-format questionnaires.

Materials And Methods: The study was conducted at the Clinic for Dental Prosthetics, University of Belgrade, Military Medical Academy and the Department of Prosthodontics of Home Centre Belgrade; the study consisted of 120 participants. A questionnaire with closed-format questions regarding the influence of applied therapy concepts for participants with Kennedy Class I partial edentulism was created.

Treatment of obstructive sleep apnea patients using oral appliances--our experiences.

Background/aim: Obstructive sleep apnea (OSA) is one of the most prevalent sleep disorders. It is recognized as a serious risk factor for car and workplace accidents due to daytime sleepiness, and factor for coronary heart diseases and stroke. The aim of this study was to examine the effectiveness of oral appliances for mandibular advance in treating mild to moderate OSA.

Finite element analysis of compressive stress and strain of different implant forms during vertical loading.

This study analyzed the influence of platform switching on the stress/strain distribution of vertically loaded implants. Employing finite element analysis, the aim of this study was to determine the distribution of stresses and strains generated by a simulated vertical load on different implant models positioned in the molar region with respect to changes of implant design and biomechanics. Two different implant designs, one with and one without platform switching, with the same length (11.

Finite element analysis in defining the optimal shape and safety factor of retentive clasp arms of a removable partial denture.

Background/aim: Retentive force of removable partial denture (RPD) directly depends on elastic force of stretched retentive clasp arms (RCAs). During deflection RCA must have even stress distribution. Safety factor is the concept which can be applied in estimating durability and functionality of RCAs.

Biomechanical behavior of restored and unrestored mandible with shortened dental arch under vertical loading condition.

The aim of this in vitro study was to investigate the strain distribution of the compressed mandible bone under the applied restoration- removable partial denture and to compare with the same but unrestored mandible under vertical (occlusal) load and to find out whether removable partial denture-restored or unrestored mandible causes greater strain effect on supporting tissue. Four mandible models were tested during loading for the purpose of strain measuring. Digital image correlation system (GOM - German Optical Measuring, Braunschweig, Germany), used for measuring strain consists of two digital cameras and software ARAMIS (6.

Prevalence, severity, and clinical determinants of oral impacts in older people in Bosnia and Herzegovina.

This study aimed to assess the prevalence and the severity of oral impacts and the relationships between oral health-related quality of life (OHRQoL) and clinical measures of oral function in a sample of older adults in Bosnia. The sample comprised 261 community-dwelling adults of ≥65 yr of age. Participants were randomly drawn from three senior day-centres for elderly people.

Optical aspect of deformation analysis in the bone-denture complex.

The aim of this study was to register and measure any deformation of mandible models under load. The method for full field measurement of strain is done by using the ARAMIS three-dimensional image correlation system. The system uses two digital cameras that provide a synchronized stereo view of the specimen and the results show the complete strain field during the tests.

The effectiveness of oral appliances in elderly patients with obstructive sleep apnoea treated with lorazepam--a pilot study.

Obstructive sleep apnoea (OSA) is one of the most common sleep disorders in elderly and represents a special problem for elderly patients. Elderly patients use a large number of drugs that might have an influence on the upper airway structure, anxiolytics or benzodiazepines being the most common. The aim of this study was to examine the effectiveness of mild or moderate OSA treatment with mandibular advance oral appliance in older lorazepam users compared with the age-matched lorazepam-free patients.

[Applicability of a Serbian version of the "Oral Impacts on Daily Performance (OIDP)" index--assessment of oral health-related quality of life].

Background/aim: The Oral Impacts on Daily Performance (OIDP) is a well-known psychometric test used internationally to assess the oral health-related quality of life. The interview and self-administrated questionnaire both assess the degree to which oral health problems have affected the life of the participants over the previous 6 months. The aim of this study was to translate the OIDP index into Serbian and to assess its reliability in practice as its initial verification in the Serbian speaking area.

Analysis of the compressive strain below the removable and fixed prosthesis in the posterior mandible using a digital image correlation method.

It was the purpose of this study to determine and analyse strains in the bone of posterior mandible below the removable and fixed partial dentures using Digital Image Correlation Method. Dried mandible with shortened dental arch (Kennedy Class 1) was used in the experiment. The mandible model was prepared for accepting two types of restorations for bilaterally missing molars conventional therapy, and removable and fixed partial dentures were manufactured following standard prosthetic protocol.

[Dedicated composite fillings--inlays].

Background: The aim of the study was to evaluate the quality and persistence of esthetics of dedicated inlay by clinical methods.

Methods: The paper reviews the clinical significance and technique of preparing particular composite inlays before and after the construction of the metallic framework partial denture. On the basis of indications the total of 30 inlays were placed into cavities under relatively dry working conditions.

[Evaluation of cermet fillings in abutment teeth in removable partial prostheses].

The aim of the study was to describe the clinical process of setting the purpose filling on abutment teeth, after finishing the removable partial dentures. The aim was also to investigate the use of cermet glass-ionomer cement for the purpose filling in the abutment teeth for removable partial dentures, as well as to investigate the surface of the purpose filling. For the clinical evaluation of purpose filling slightly modified criteria according to Ryg's were used in 20 patients with different type of edentulousness.
