Impact of hypomineralised second primary molar on preschoolers' oral health–related quality of life—A hierarchical approach

Abstract

Background Hypomineralised second primary molar (HSPM) is a developmental enamel defect associated with dental caries. Aim To evaluate the impact of HSPM on oral health–related quality of life (OHRQoL) in preschoolers through hierarchical analysis. Design This population‐based cross‐sectional study assessed 834 5‐year‐old preschoolers, in Teresina, Piauí, Brazil, using sociodemographic questionnaires and Early Childhood Oral Health Impact Scale (ECOHIS). Dental examination was performed by two calibrated examiners (κ ≥ 0.80) for the diagnosis of HSPM (EAPD), dental caries (dmft and pufa indices), and malocclusion (Foster and Hamilton criteria). Analysis of the determinants of OHRQoL was stratified at three levels (P < .05). Results Severe HSPM was associated with OHRQoL in bivariate analysis (P < .05). In adjusted final multivariate analysis (model 1), the presence of dental caries with or without clinical consequences was associated with worse OHRQoL (P < .05). In model 2, after the removal of dental caries, preschoolers with severe HSPM had greater probability of having a negative impact on OHRQoL in the child impact section (RR = 2.14; 95% CI = 1.26‐3.65), family impact section (RR = 1.99; 95% CI = 1.16‐3.42), and total score (RR = 2.09; 95% CI = 1.25‐3.49) of the ECOHIS. Conclusion Severe HSPM had a negative impact on the OHRQoL of preschoolers and their families, but the presence of dental caries neutralised this impact.

Dental enamel defects and dental caries of primary teeth among Indigenous children in Western Australia

“…The occurrence of dental EDs, particularly demarcated opacities, has been reported to be associated with an increased risk of caries in permanent and primary teeth 6–12 and findings from a few studies suggest that hypomineralized EDs might predispose teeth to a more rapid progression of caries, thus leading to poorer carious outcomes where access to care may be limited 7,8 . Also, hypomineralized EDs of second primary molars have been reported to be associated with poorer oral health‐related quality of life 13 …”

“…7,8 Also, hypomineralized EDs of second primary molars have been reported to be associated with poorer oral health-related quality of life. 13 There is limited information available on the occurrence of EDs among the Indigenous population in Australia. The national Australian child oral health study of 2012-2014 recorded the presence of enamel hypoplasia (detectable loss of enamel) in permanent and primary teeth, and reported a higher prevalence among the Indigenous than non-Indigenous children, 13.3% and 10.1% respectively.…”

Fatores materno-infantis e associação com defeitos de desenvolvimento do esmalte dentário na dentição decídua na coorte de nascimento MINA-Brasil

“…Esta implicação clínica pode ser explicada pelo fato de haver uma maior suscetibilidade para o desenvolvimento de lesões de cárie possivelmente devido às malformações do esmalte, maior risco de fraturas pós-irruptivas e presença de hipersensibilidade o que poderia facilitar a adesão e colonização de microrganismos com potencial cariogênico e maior acúmulo de biofilme (Li et al, 1994;Corrêa-Faria et al, 2015;Costa et al, 2017;Cerqueira Silva et al, 2022).…”
