Influence of functional dentition on satisfaction with oral health and impacts on daily performance among Brazilian adults: a population-based cross-sectional study

Abstract

BackgroundDental esthetics, chewing and speech should be preserved in a dentition denominated functional and are closely related to satisfaction with oral health (SOH), impacts caused by oral problems and have a possible association with Oral Health-Related Quality of Life. Thus, the purpose of the present study was to investigate the influence of different concepts of functional dentition (FD) on both SOH and impacts on daily performance (IDP) among Brazilian adults.MethodsA cross-sectional study was conducted with 9564 adults (35–44 years). SOH and IDP were evaluated using the Oral Impacts on Daily Performance (OIDP) questionnaire. FD was considered based on four different definitions: I-classification of the World Health Organization (FDWHO = ≥20 teeth); II-well-distributed teeth (WDT = ≥10 teeth in each arch); III-classified by esthetics and occlusion (FDClass5 = sequential presence of one tooth in each arch, ≥10 teeth in each arch, 12 anterior teeth, ≥three posterior occluding pairs [POPs] of premolars and ≥one POP molar bilaterally); and IV-classified by esthetics, occlusion and periodontal status (FDClass6 = FDClass5 plus all sextants with CPI ≤ 3 and/or CAL ≤ 1). The proportion of adults satisfied with oral health and without overall impact (OIDP = 0) was calculated for each definition of FD. Multiple Poisson regression models were adjusted by demographic-socioeconomic characteristics, self-reported oral problems and the use of dental services for each dependent variable.ResultsWhen FDClass5 and FDClass6 were considered a greater proportion of adults reported being satisfied (52.1 and 53.1%, respectively) and have OIDP = 0 (52.4 and 53.3, respectively). In the multiple models, SOH was associated with FDClass5 (RP = 1.21) and FDClass6 (RP = 1.24) and OIDP = 0 was associated with WDT (RP = 1.14) and FDClass6 (RP = 1.21).ConclusionsThe greater influence of WDT, FDClass5 and FDClass6 on aspects related to quality of life in comparison to FDWHO demonstrates the need for the establishment of a broader definition of FD that encompasses subjective aspects.

Oral impacts mediate the association between reduced dentition and self-perceived need for complete dentures

“…This mediation indicates that aspects of daily living related to the teeth and mouth should be addressed to gain a better understanding of the selfperceived need for CD and should be considered when developing educational actions directed at adults with the aim of preserving the teeth and their functions. This finding is consistent with previous evidence of greater satisfaction with oral health and a greater frequency of an absence of impact (OIDP = 0) among adults with a functional dentition (FD ClassV ) [3].…”

“…Individuals with "less than 10 teeth in each arch, 12 anterior teeth, with or without > 3 premolar POPs, with or without > 1 molar POP bilaterally" did not have a significantly greater frequency of a self-perceived need for CD compared to those with "10 teeth in each arch, < 12 anterior teeth, with or without > 3 premolar POPs, with or without > 1 molar POP bilaterally". This finding suggests that the presence of anterior teeth favors a more positive perception of the teeth even when individuals do not have 10 teeth in each arch, which may be explained by the importance attributed to esthetics and the strong associations between the anterior teeth and satisfaction with one's mouth, psychofunctional wellbeing and the absence of impact [3,[29][30][31][32]. This may be due to the key role the anterior teeth play in the personal image of individuals [32] and their social relations [27], as the frequency of impact on smiling/speaking is lower among those who have complete anterior sextants [3].…”

“…Indeed, associations have been found between reduced dentitions and general quality of life [5] as well as oral health-related quality of life (OHRQoL) [3,[6][7][8]. Reduced dentitions have been assessed using different definitions based only on the number or the type, location and function of remaining teeth.…”

“…Reduced dentitions have been assessed using different definitions based only on the number or the type, location and function of remaining teeth. There is a consensus in the literature that reduced dentitions with the preservation of the anterior teeth and posterior occlusal units are compatible with quality of life and satisfaction [3,9]. In contrast, a greater number of missing teeth is associated with a negative perception of oral health [10,11] and general health [12] as well as lower general quality of life [5] and OHRQoL [4].…”

Understanding behavioural changes through community-based participatory research to promote oral health in socially disadvantaged neighbourhoods in Southern Sweden

“…23 Oral health impairments have a considerable impact on the quality of life of affected individuals both functionally and aesthetically. [24][25][26] Poor oral hygiene and excessive or frequent intake of sugar between meals are leading causes for caries and poor oral health in general. 27 The consumption of fermentable carbohydrates containing added sugars has been on the rise, particularly among children and young adults.…”
