Retention behaviors of different attachment systems: precious versus nonprecious, precision versus semi-precision.

The aims of this study were to investigate the retention force changes of different attachment systems after 10,000 insertion-separation cycles and the difference in retention force between precious and non-precious materials of the same attachment system. Four types of attachments (Ball, Rod, M3 stud, and AP-Piccolino), produced using both precious and non-precious metal alloys, were tested (n=6). Data were analyzed using analysis of variance (ANOVA), Tukey's multiple comparison test, and t-test at a significance level of p≤0.05. Retention forces of all attachment types were significantly decreased after 10,000 insertion-separation cycles (p≤0.05). Rod and M3 attachment systems showed an initial increase in retention force, then an eventual decrease. At the end of the test, precious types of M3 and AP-Piccolino attachments had significantly higher retention force values than their non-precious ones (p≤0.05). Friction between non-precious attachment parts resulted in a higher retention loss than precious metal alloys.

The association between socioeconomic status, oral hygiene practice, denture stomatitis and oral status in elderly people living different residential homes.

Oral hygiene practices and denture status of elderly people living in residential homes are different depending on the type of residential homes. In this study the elderly people living in three different residential homes were investigated for this purpose. A total of 269 subjects, 119 males (mean age 73.9±8.8) and 150 females (mean age 78.5±7.2) were involved in this study. All subjects were interviewed and clinically examined. Age, sex, educational status, financial status, general health, dental visiting, overnight denture wearing, brushing habits and frequency were recorded using a structured questionnaire. The prevalence of edentulism, the presence and type of dental prostheses, denture cleanliness and the presence of denture stomatitis were evaluated. Forty-one percent of subjects were non-educated. Fifty-one percent of subjects had low income. The majority of people (66.6%) were edentulous. Among the edentulous subjects 32% had full denture and 16% had no denture. Forty three percent of the subjects reported cleaning their dentures with water and 40% with a toothbrush only. Denture hygiene was good for 14% of the subjects. Denture stomatitis was observed in 44% of the subjects wearing dentures. There was statistically significant difference between residential homes and educational status, level of income, dental visiting, denture status, brushing methods and brushing frequency (p<0.001). A positive relationship was observed between poor denture hygiene habits and the presence of denture-related stomatitis. The most important need within the residents of the residential home was the enhancement of oral care social insurance.

Oral health status and treatment requirements of different residential homes in Istanbul: a comparative study.

The purpose of this study was to investigate dental/denture status of the elderly people living in different residential homes. In 346 elderly people from different residential homes two belonging to the state (Group 1 and Group 2) and one supported by private foundations (Group 3) were examined. Sixty percent of participants were edentulous and 22.8% of participants had no complete dentures which 9 (7.4%) of them were in Groups 1 and 2. Over 50% of the participants had no or low income and 45% of participants were illiterate. All of the participants who were illiterate and had low income were in Group 1 and Group 2. Oral hygiene was good for 15.4% and only 19.4% of participants removed their dentures overnight. Denture stomatitis was observed in 61.7% of subjects. Significant correlation was found between denture hygiene and age of participant, general health status, denture stomatitis, and overnight denture wear (p=0.001). The decayed, missing and filled teeth (DMFT) scores were 25.52±3.37. There was statistically significant differences between groups for DMFT scores (p=0.016). Dental health education is also needed focusing on the special needs of this neglected and socioeconomically deprived population to improve their quality of life.

Prosthodontic rehabilitation after traumatic tooth and bone loss: a clinical report.

Traumatic injuries from motor vehicle accidents may cause anatomic deficiencies in soft and hard tissues. Successful treatment of patients with such deficiencies may include preprosthetic surgery using osseointegrated implants to increase prosthesis retention and stability. This article describes the treatment of a motor vehicle accident victim whose anterior teeth and supporting tissues were lost.
