“…The study also observed no association between DMH, MIH and the socioeconomic status of the child thereby confirming the observation made by Oyedele et al [ 19 ] in the study environment. This observation differs from prior observation on the relationship between prevalence of enamel defects and socioeconomic status [ 38 , 40 , 41 ]. Like Oyedele et al [ 19 ] observed, the non-association between DMH, MIH and socioeconomic may serve as a distinguishing feature between enamel hypoplasia and DMH/MIH in the study environment.…”

BackgroundMolar Incisor Hypoplasia (MIH) and Deciduous Molar Hypoplasia (DMH) have significant impact on the quality of life of affected individuals. The objective of the study was to determine the prevalence, pattern and clinical presentation of MIH and DMH in children resident in Ile-Ife, Nigeria, and their association with sex and socioeconomic status of the children.MethodsInformation on age, sex and socioeconomic status was collected from 563 children aged 3 to 5 years and 8 to 10 years using a structured questionnaire through a household survey. Clinical examination was conducted to assess for the presence of DMH and MIH. The prevalence of DMH and MIH were determined. Tests of association between sex, socioeconomic status, prevalence, and pattern of presentation of both DMH and MIH were conducted using Pearson’s Chi-squared test Fisher’s exact test.ResultFifteen (4.6 %) of the 327 children aged 3 to 5 years and 23 (9.7 %) of the 237 children aged 8 to 10 years had DMH and MIH respectively. There were no significant association between DMH, sex (p = 0.49) and socioeconomic status (p = 0.32). There were also no significant association between MIH, sex (p = 0.31) and socioeconomic status (p = 0.41). MIH/DMH co-morbidity was observed in eight (34.8 %) of the 23 children with MIH. The mandible and maxilla were affected equally. Antimere was not observed.ConclusionThe prevalence of DMH and the prevalence of MIH in the study population were high. DMH and MIH were not associated with sex and socioeconomic status. There was no specific pattern identified in the presentation of DMH and MIH. The prevalence of DMH/MIH co-morbidity is also high. Patients with DMH should be screened for MIH.

“…In an histological study, Koch and co‐workers () used microscopy to show that six of seven children with chronic renal failure had LHPC; none was affected by preterm onset. Despite these clear demonstrations that LHPC occurred postnatally, there appears to be some reluctance to abandon the view that LHPC is a perinatal problem, at least in Miocene catarrhines (Lukacs, ) or may occur even as early as midway through pregnancy (Orenuga and Odukoya, ). Some argue that even though fenestration and defect formation occur postnatally, it is prenatal stress that predisposes to the defect (Halcrow and Tayles, ).…”

Hypoplastic pits on human deciduous canine teeth are attributed to nutritionally induced thinning of the crypt wall prior to eruption, exposing ameloblasts to unspecified physical trauma through the fenestration. Traditionally known as localized hypoplasia of the primary canine (LHPC), this little-understood condition is reported in fields ranging from public health to bioarchaeology. We propose the defect be termed a ‘crypt fenestration hypoplastic enamel defect’ (CFED) to reflect that an analogous lesion is created postnatally on maxillary molars of pigs. Pigs are accepted as a suitable proxy for many studies in human biology. We compare fenestration defects and CFEDs between 50 Sick Pen pigs, who died naturally, and 20 Controls. Observations were made of the presence, number and size of fenestrations in molar crypts. CFEDs were counted on erupted deciduous last molars and permanent first molars. Signs of being underweight and cranio-dental infection at death were recorded. Sick pen pigs show significantly more fenestrations at death and CFEDs acquired before death. These conditions co-occur with infection and poor growth. The deep fibers of temporalis muscle lie adjacent to the crypt wall of maxillary molars. We propose that contraction of this muscle during suckling and chewing creates large compressive forces against fenestrated bony surfaces sufficient to have physiological consequences for physically unprotected ameloblasts. While we conclude that a pig model is appropriate to study fenestration-induced enamel defects, this naturalistic experiment leaves unresolved whether osteopenia in pigs, and by extension in human infants, is due to disease and/or malnutrition.

“…Past studies conducted in Nigeria showed a high prevalence of MIH [ 20 , 21 ] and enamel hypoplasia [ 22 , 23 ]. The prevalence of MIH ranged between 9.7% and 17.7% [ 20 , 21 ], while that of enamel hypoplasia ranged between 0.13% and 3.6% in the permanent dentition [ 22 – 26 ] and 2.3% to 4.0% in the primary dentition [ 23 , 27 ]. Co-existence of MIH and enamel hypoplasia had also been described [ 28 ].…”

Developmental defects of the enamel and its impact on the oral health quality of life of children resident in Southwest Nigeria

BackgroundDevelopmental defects of the enamel (DDE) increase the risk for diseases that impact negatively on the quality of life. The objective of this study was to compare the oral health quality of life of children with molar-incisor-hypomineralisation (MIH) and enamel hypoplasia; and assess if caries worsened the impact of these lesions on the quality of life.MethodsThis study recruited 853 6 to 16-years-old school children. They filled the Child-OIDP questionnaire. The MIH, enamel hypoplasia, caries and oral hygiene status was assessed. Poisson regression was used to determine the impact of MIH and enamel hypoplasia on the oral health quality of life, after adjusting for the effect of sex, age, socioeconomic class, oral hygiene and caries status.ResultsThe prevalence of MIH and enamel hypoplasia was 2.9% and 7.6% respectively. There was no significant difference in the mean child-OIDP scores of children with or without MIH (p = 0.57), children with or without enamel hypoplasia (p = 0.48), and children with enamel hypoplasia with and without caries (p = 0.30). Children with enamel hypoplasia and caries had worse outcomes for speaking (p = 0.01). Children with middle (AOR: 2.74; 95% CI: 1.60–4.67; P < 0.01) and low (AOR: 1.75; 95% CI: 1.04–2.95; p = 0.03) socioeconomic status, and those with caries (AOR: 2.02; 95% CI: 1.26–3.22; p = 0.03) had their oral health quality of life negatively impacted.ConclusionMIH and enamel hypoplasia had no significant impact on the overall oral health quality of life of children resident in southwestern Nigeria. However, children with caries and those from middle and low socioeconomic classes had poorer oral health quality of life.
