This study shows that for children aged 5-12 years, prior experience of the dental setting can act as a positive component of dental fear.
Nutritional status, dietary intake and oral quality of life in elderly complete denture wearers Background and objective: The prevalence of malnutrition increases with age because of many factors. Edentulousness leads to the avoidance of many types of foods. The aim of this study was to determine whether elderly complete denture wearers have a higher risk of malnutrition than dentate controls. Material and methods: A Mini-Nutritional Assessment (MNA) and a 3-day dietary record were compiled for a group of fully dentates (21 women and 29 men; mean age 70.1 ± 6.1) and for a group of complete denture wearers (31 women and 16 men; mean age 70.1 ± 8.1). Socio-demographic data and scores on the General Oral Health Assessment Index (GOHAI) questionnaire were collected. Results: Inter-group comparison of MNA scores showed that more subjects in the edentulous group (21.3%) risked malnutrition than in the dentate group (0%). The variability of the MNA could be explained for 22% by dental status, 7% by loneliness and 4% by the GOHAI score (regression analysis). Both groups had insufficient energy intakes and deficits in vitamins and micronutrients; moreover, edentulous subjects had lower intakes than dentate subjects. Conclusion: The use of conventional dentures increases the risk of malnutrition in the elderly.
BackgroundVery few studies on the impact of implant therapy on Oral Health Related Quality of Life (OHRQoL) in partially edentulous patients have been published.AimThis study aimed at analysing the improvement of OHRQoL of patients who underwent dental implant treatment using the “functional”, “psychosocial” and “pain and discomfort” categories of the Geriatric Oral Health Assessment Index (GOHAI).MethodsWithin a prospective cohort of patients rehabilitated with Straumann dental implants, the OHRQoL of 176 patients (104 women and 72 men) was assessed using the GOHAI questionnaire, at two different times, before and after implant placement. The degree of oral treatment was categorised into three classes: “Single Tooth Implant” (n = 77), “Fixed Partial Denture” (n = 75), “Fixed or Retained Full Prostheses” (n = 24). The participants’ characteristics (gender, age, tobacco habits, periodontal treatment, time between both evaluations) were assessed.ResultsBefore treatment, the GOHAI score was lower for participants with fewer teeth (F = 19, P < 0.001). After treatment, no difference was observed between participants; significant improvements were observed in the GOHAI scores obtained (repeated measures, analysis, (F = 177, P < 0.001)) for each of the GOHAI fields studied (functional, psychosocial and pain & discomfort), regardless of the degree of treatment. The best improvement was observed in patients who needed complete treatment (P < 0.001). The presence of preliminary periodontal treatment, tobacco habits, age and gender of the participants did not have a significant impact on OHRQoL. Changing the time between the two evaluations (before and after treatment) had no impact on the changes in the GOHAI score.ConclusionsImplants enhanced the OHRQoL of participants that needed oral treatment.
Removable partial denture prostheses are still being used for anatomic, medical and economic reasons. However, the impact on chewing parameters is poorly described.ObjectivesThe objective of this study was to estimate the impact of removable partial denture prosthesis on masticatory parameters.Material and MethodsNineteen removable partial denture prosthesis (RPDP) wearers participated in the study. Among them, 10 subjects were Kennedy Class III partially edentulous and 9 with posterior edentulism (Class I). All presented a complete and full dentate opposing arch. The subjects chewed samples of carrots and peanuts with and without their prosthesis. The granulometry of the expectorated boluses from carrot and peanuts was characterized by median particle size (D50), determined at the natural point of swallowing. Number of chewing cycles (CC), chewing time (CT) and chewing frequency (CF=CC/CT) were video recorded.ResultsWith RPDP, the mean D50 values for carrot and peanuts were lower [Repeated Model Procedures (RMP), F=15, p<0.001] regardless of the type of Kennedy Class. For each food, mean CC, CT and CF values recorded decreased (RMP, F=18, F=9, and F=20 respectively, p<0.01). With or without RPD, the boluses' granulometry values were above the masticatory normative index (MNI) determined as 4,000 µm.ConclusionRPDP rehabilitation improves the ability to reduce the bolus particle size, but does not reestablish fully the masticatory function.Clinical relevanceThis study encourages the clinical improvement of oral rehabilitation procedure.
