Using Written Vignettes in Focus Groups Among Older Adults to Discuss Oral Health as a Sensitive Topic

When the mouth yields pain and distress, it can impact psychosocially the lives of older adults and might constitute a sensitive topic for open disclosure. In this article, we describe our use of a written vignette in focus groups for discussion of oral health and disablement. Six focus groups were conducted with 42 older men and women with an average age of 75 years who were purposefully selected through advertisements posted in community centers and retirement homes. In discussions lasting for an average of 90 min, groups of up to 9 participants commented positively and negatively on the vignettes story and voluntarily discussed their personal experiences, family histories, and testimonies about the mouth and coping and adapting strategies to disabilities. The discussion about oral health can be sensitive, but the vignette shifted the focus away from the participants and allowed them to share personal experiences with oral health and disablement.

Crestal bone loss proximal to oral implants in older and younger adults

STATEMENT OF PROBLEM Older adults often have bone loss and may be at risk of bone resorption around oral implants. PURPOSE This study tested the hypothesis that there is no difference in crestal bone loss proximal to oral implants in the complete implant prosthesis sites of older and younger adults. MATERIAL AND METHODS Two groups of 35 complete dental implant prosthesis sites (23 screw-retained fixed prostheses and 12 bar-retained overdentures) were selected by matching sites in 32 older adults (60 to 74 years old with 166 Bränemark implants) to sites in 34 younger adults (29 to 49 years old with 162 Bränemark implants) on the basis of possible confounding factors including gender, prosthetic design, implant number, arch, year of surgery, and opposing dentition. Statistical comparisons (Mann-Whitney test at P<.05) were made of mean crestal bone level at loading and mean annual crestal bone loss during the first year, first to fourth year, after first year, and after fourth year of loading with periapical radiographic measurements of the vertical distance in millimeters from the apical edge of the implant collar to the most apical initial point of contact between the implant and bone. RESULTS No significant differences were found between the groups. Mean bone levels at loading were 1.4 mm below the collar in both groups and mean annual crestal bone loss after the first year of loading was 0.04 mm/y in both groups. However, significant differences were found between some old and young subgroups stratified by arch and prosthetic design. CONCLUSION Within the limitations of this study, elders should expect no more rapid bone resorption around oral implants in edentulous jaws than that seen in young adults.

Attachment systems for mandibular implant overdentures: a systematic review

PURPOSE The aim of this systematic review was to address treatment outcome according to attachment systems for mandibular implant overdentures in terms of implant survival rate, prosthetic maintenance and complications, and patient satisfaction. MATERIALS AND METHODS A systematic literature search was conducted using PubMed and hand searching of relevant journals considering inclusion and exclusion criteria. Clinical trial studies on mandibular implant overdentures until August, 2010 were selected if more than one type of overdenture attachment was reported. Twenty four studies from 1098 studies were finally included and the data on implant survival rate, prosthetic maintenance and complications, patient satisfaction were analyzed relative to attachment systems. RESULTS Four studies presented implant survival rates (95.8 - 97.5% for bar, 96.2 - 100% for ball, 91.7% for magnet) according to attachment system. Ten other studies presented an implant survival rate ranging from 93.3% to 100% without respect to the attachment groups. Common prosthetic maintenance and complications were replacement of an assay for magnet attachments, and activation of a matrix or clip for ball or bar attachments. Prosthetic maintenance and complications most commonly occurred in the magnet groups. Conflicting findings were found on the rate of prosthetic maintenance and complications comparing ball and bar attachments. Most studies showed no significant differences in patient satisfaction depending upon attachment systems. CONCLUSION The implant survival rate of mandibular overdentures seemed to be high regardless attachment systems. The prosthetic maintenance and complications may be influenced by attachment systems. However patient satisfaction may be independent of the attachment system.

Number of implants for mandibular implant overdentures: a systematic review

PURPOSE The aim of this systematic review is to address treatment outcomes of Mandibular implant overdentures relative to implant survival rate, maintenance and complications, and patient satisfaction. MATERIALS AND METHODS A systematic literature search was conducted by a PubMed search strategy and hand-searching of relevant journals from included studies. Randomized Clinical Trials (RCT) and comparative clinical trial studies on mandibular implant overdentures until August, 2010 were selected. Eleven studies from 1098 studies were finally selected and data were analyzed relative to number of implants. RESULTS Six studies presented the data of the implant survival rate which ranged from 95% to 100% for 2 and 4 implant group and from 81.8% to 96.1% for 1 and 2 implant group. One study, which statistically compared implant survival rate showed no significant differences relative to the number of implants. The most common type of prosthetic maintenance and complications were replacement or reattaching of loose clips for 2 and 4 implant group, and denture repair due to the fracture around an implant for 1 and 2 implant groups. Most studies showed no significant differences in the rate of prosthetic maintenance and complication, and patient satisfaction regardless the number of implants. CONCLUSION The implant survival rate of mandibular overdentures is high regardless of the number of implants. Denture maintenance is likely not inflenced substantially by the number of implants and patient satisfaction is typically high again regardless os the number of implants.

Oral healthcare challenges for older Punjabi-speaking immigrants.

Cette étude a exploré comment les immigrants âgés d’origine sud-asiatique, parlant le pendjabi (quatre groupes de discussion; 33 participants) de Surrey en Colombie-Britannique, perçoivent leur santé buccale et les problèmes connexes. L’analyse a relevé deux thèmes généraux: les interprétations de la condition bucco-dentaire et les défis de santé buccodentaire. Le thème des interprétations avait quatre sous-thèmes: les dommages causés par le wai, les perturbations causé par la carie, l’adaptation aux prothèses dentaires, et qualité de vie; alors que le thème des défi s considérés: remèdes à domicile, dentisterie occidentale; et difficultés d’accès aux dentistes. Les participants ont expliqué les maladies buccodentaires en termes d’une infection systémique (resha) et ont dit préféré les remèdes faits maison pour diminuer les écarts de chaleur (wai) dans la bouche. Nous concluons que les immigrants âgés d’origine sud-asiatique parlant le pendjabi interprète la santé et les maladies bucco-dentaires dans un contexte mixte de traditions occidentales et Ayurvédique, et gèrent leur santé buccale au moyen de remèdes traditionnels faits maison, complémentés au besoin par des soins d’urgence dispensés au Canada.This study explored how older Punjabi-speaking South-Asian immigrants (four focus groups; 33 participants) in Surrey, British Columbia, perceive oral health and related problems. Content analysis revealed two umbrella themes: (a) interpretations of mouth conditions and (b) challenges to oral health. The umbrella themes had four sub-themes: damage caused by heat (wai), disturbances caused by caries, coping with dentures, and quality of life. Three challenges were considered: home remedies, Western dentistry, and difficulties accessing dentists. Participants explained oral diseases in terms of a systemic infection (resha), and preferred to decrease imbalances of wai in the mouth with home remedies from India. We conclude that older Punjabi-speaking immigrants interpret oral health and disease in the context of both Western and Ayurvedic traditions, and that they manage dental problems with a mix of traditional remedies supplemented, if possible, by elective oral health care in India, and by emergency dental care in Canada.
