“…In both males and females, lower BMI is associated with a delay in the age of attainment of the final H dental developmental stage. This is in agreement with previous studies that found a significant influence of nutrition on tooth formation in children from the United States (Hilgers et al, ; Mack et al, ) and Iran (Zangouei‐Booshehri et al, ). The findings of the present study are at variance with three previous reports of no significant difference in the dental development of underweight or overweight children (Bagherian & Sadeghi, ; Eid et al, ; Elamin & Liversidge, ).…”

“…Studies from Peru, Brazil, Iran, and Northern Sudan that used BMI as a proxy for nutritional status found no significant influence of BMI on tooth formation (Bagherian & Sadeghi, ; Cameriere et al, ; Eid et al, ; Elamin & Liversidge, ). In contrast, other studies (DuPlessis, Araujo, Behrents, & Kim, ; Hilgers et al, ; Mack, Phillips, Jain, & Koroluk, ; Zangouei‐Booshehri, Ezoddini‐Ardakani, Aghili, & Sharifi, ) showed dental development was significantly accelerated with higher BMI, even after adjusting for age and sex. This developmental advancement was attributed to accelerated linear growth and early sexual maturation, which is usually associated with obesity (Sánchez‐Pérez, Irigoyen, & Zepeda, ; Slyper, ).…”

Background: The effect of nutritional status on the timing of permanent tooth formation is not well understood, despite clear evidence that systemic stresses result in enamel defects during tooth formation.Aim: This study investigated the effect of nutritional status (measured as BMI, height, weight, mid-upper arm circumference, and head circumference) on permanent tooth formation.Method: This was a prospective cross-sectional study involving 642 (270 males, 372 females) healthy Black South African participants aged 5-20 years. The height and BMI were converted to z-scores using WHO z-score for age tables. The participants were grouped into underweight/short for age (<−2), normal (≥ − 2 to 2.0) and overweight/obese/tall for age (>2). Panoramic radiographs of the children were assessed using Demirjian's eight stages of permanent tooth formation and age was estimated using Demirjian's method. Probit regression analysis was used to calculate the mean age of attainment of the developmental stages for the left mandibular teeth (I2-M2).Results: There was significant advancement in the age of attainment of the final (H) stage for the majority of permanent teeth in the overweight (mean male BMI 22.9; female 27.94) group compared to the underweight (p < .05). Negative binomial regression indicated that age, height, and BMI were significant predictors of the dental maturity score for males (p < .05), while age, height, weight, BMI and HC were significant predictors for females (p < .05).Conclusion: Nutritional status had a significant effect on the timing of tooth formation in males and females in the study population. The effect was mainly noticeable for children in the extremes of the spectrum of BMI z-scores.

“…[23][24][25][26] Underweight children showed retarded eruption of teeth, this is consistent with a study done in India by Manjunatha (2014) and in Germany by Heinrich-Weltzien et al (2013), who reported that underprivileged children show comparative retarded eruption relative to their ethnic counterparts from higher socioeconomic status. 27,28 In our study, major differences of eruption times of teeth were present among children with the same chronological age which is consistent with a study done in Iran by Booshehri et al (2011), who also concurred that same finding.

“…4,5 As teeth are the most stable structures in the human body, it can be of paramount importance in forensic medicine where estimation of age is usually required for criminal investigations and also in persons who do not have proper birth certificates whether above or below 18 years of age. 6,7 Body Mass Index (BMI) is a reliable table for measurement of obese people and for those who are overweight especially teenagers and small kids. BMI is reliant on age and gender in kids and teenagers and is for the most part stated to as particular for a specific age 8 but, no sound research has been performed in Pakistan on the assessment of eruption of permanent teeth according to age and its relation with body mass index.…”

ABSTRACT:Objectives of the present study was to find out the assessment of eruption of permanent teeth according to age and its relation with body mass index in local population. Three hundred School children were included in this study. The study was conducted from 1st March to 31st May 2016. The schools selected for research were Pak Turk International School (Isra University), Isra School (Hadi Nagar) and Government primary School, Village Haji Ismail Khan Chand (Hala Naka). Data was collected by measuring the height, weight and oral examination of each child. The height and weight were later used to calculate the child's B.M.I. A sample of 300 children was studied; 100 each of different socioeconomic school. The Mean age and standard deviation was 9.86 ± 2.057 years respectively. Frequency of male to female subjects remained 150 (50%) and 150 (50%) respectively. Age category was from 5 to 15 years of age. It was seen that children were mostly in the normal weight category other than children of age 8 & 10 where underweight children were seen in excess. It was found that almost all teeth had slight delayed eruption according to the normal eruption time but since the sample size was not big enough therefore we cannot conclude that every child in our region will have delayed eruption. In our sample the highest variation was seen in mandibular left second molar where delayed eruption was present. KEY WORDS: B.M.I., eruption, permanent teeth, socioeconomic status, age HOW TO CITE: Hassan S, Shahid H. Assesment of eruption of permanent teeth according to age and its relation with body mass index in local population.

“…Heavier children showed a slight advancement in tooth formation across all ages evidenced by negative correlation of age of tooth stage and body fat [2]. Accelerated dental maturity was observed in obese or overweight children compared to normal and underweight children [22], [23] but subgroups consisted of only15 or 16 over a wide age range. Accelerated dental maturity was reported in 23 overweight and 18 obese children aged 8 to 15 [24].…”

Malnutrition Has No Effect on the Timing of Human Tooth Formation

The effect of nutrition on the timing of human tooth formation is poorly understood. Delays and advancements in dental maturation have all been reported as well as no effect. We investigated the effect of severe malnutrition on the timing of human tooth formation in a large representative sample of North Sudanese children. The sample (1102 males, 1013 females) consisted of stratified randomly selected healthy individuals in Khartoum, Sudan, aged 2-22 years using a cross-sectional design following the STROBE statement. Nutritional status was defined using WHO criteria of height and weight. Body mass index Z-scores and height for age Z-scores of ≤−2 (cut-off) were used to identify the malnourished group (N = 474) while the normal was defined by Z-scores of ≥0 (N = 799). Clinical and radiographic examination of individuals, with known ages of birth was performed including height and weight measurements. Mandibular left permanent teeth were assessed using eight crown and seven root established tooth formation stages. Mean age at entry and mean age within tooth stages were calculated for each available tooth stage in each group and compared using a t-test. Results show the mean age at entry and mean age within tooth stages were not significantly different between groups affected by severe malnutrition and normal children (p>0.05). This remarkable finding was evident across the span of dental development. We demonstrate that there is little measurable effect of sustained malnutrition on the average timing of tooth formation. This noteworthy finding supports the notion that teeth have substantial biological stability and are insulated from extreme nutritional conditions compared to other maturing body systems.
