Prevalence of hypomineralised second primary molars (HSPM): A systematic review and meta‐analysis

Abstract

Enamel hypomineralisation is a qualitative defect of the enamel resulting from a disturbance during initial calcification and/or maturation. 1,2 This condition in first permanent molars/incisors is known as molar incisor hypomineralisation (MIH). 2 In the primary dentition, a similar presentation has been observed in the second primary molar, which is now termed hypomineralised second primary molars (HSPM). 2-4 HSPM is currently defined as

The prevalence and characteristics of and the association between MIH and HSPM in South‐Western France

“…In the present study, 4.9% of the overall sample had both HSPM and MIH, similar to previous reports. 26 Ghanim et al 24 reported that 40% of children with HSPM suffered from MIH. Negre-Barber et al 27 report that 76% of children with HSPM also had MIH and that 11% of the total sample had HSPM and MIH simultaneously.…”

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

“…4 The worldwide prevalence of hypomineralized EDs of the primary molars has been reported to range from 0% to 41% at the individual level with a pooled prevalence of 7%, and ranged from 0% to 30% at the tooth level, with a pooled prevalence of 4%. 5 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][7][8][9][10][11][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.…”

“…The global prevalence of EDs defined as molar incisor hypomineralization (EDs of the first permanent molars and incisors) has been estimated to be 13% with over 840 million prevalent and incident cases in 2015–2016 4 . The worldwide prevalence of hypomineralized EDs of the primary molars has been reported to range from 0% to 41% at the individual level with a pooled prevalence of 7%, and ranged from 0% to 30% at the tooth level, with a pooled prevalence of 4% 5 . 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 .…”

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

“…A grande variação na prevalência de DDE em dentes decíduos relatada na literatura pode ser influenciada por diversos fatores, como a idade da população investigada, visto que o desgaste dentário (desgaste dentário erosivo, atrito, abrasão) e lesões de cárie são fatores que estão associados ao DDE (Kazouilis et al, 2007;Costa et al, 2017;Kirthiga et al, 2019) o pode dificultar o diagnóstico e consequentemente, haver uma subestimação na prevalência de DDE, principalmente em estudos transversais (Elfrink et al, 2014;Seow, 2015;Wagner, 2016;McCarra et al, 2022).…”

“…Há poucos estudos populacionais de desenho longitudinal no início da vida, que As diferenças de prevalência podem estar relacionadas a algumas questões como o uso de diferentes critérios e falta de protocolos padronizados para o diagnóstico e coleta de dados (Seow, 2015;Ruschel et al, 2019). Além disso as características pertinentes as populações estudadas como fatores socioeconômicos e ambientais, etnia, exposição ao flúor e perfil de saúde, podem influenciar na diferença dos achados (Elfrink et al, 2014;Seow, 2015;McCarra et al, 2022).…”
