“…Liversidge and Molleson provide one of the very few studies that suggest that there are no significant population differences in the timing of deciduous tooth maturation. Some populations have been shown to differ in deciduous tooth emergence , but these may not reflect population differences in tooth formation and have been linked to differences in health and nutrition , which has been supported by other studies . In contrast, mortality bias has been shown to have no impact on deciduous tooth emergence , but again that does not mean that tooth formation is also not affected.…”

This study provides an update on a quantitative method for immature age estimation based on postnatal deciduous mandibular tooth length. Two known sex and age skeletal collections from Western Europe were sampled (n = 97). Linear regression models for age estimated were calculated for each individual tooth, each sex, and sex combined sample using classical calibration. Prediction errors, residuals, and percentage of individuals whose real age fell within the 95% prediction interval were calculated. The teeth which develop earlier in life, the incisors and the first molar, showed the greatest precision, while the canine showed the least. This method has greater applicability to archeological skeletons or to children in developing countries than for use in North American or European forensic contexts. The method can be applied to incomplete or poorly preserved remains of unknown sex, particularly when dental radiographs are not an option or when teeth have been removed from the alveolus or crypt.

“…However, external environmental factors also make significant contributions to the timing of the primary tooth eruption. Maternal exposure to tobacco during pregnancy 7,8 , infant birth weight 9,10 , birth length 11 , nutritional state at birth and at postnatal timepoints 12 , gestational age 13 , method of infant feeding 8,14 and socioeconomic situation 15 have been reported to be significant determinants of the eruption of primary teeth. Delayed tooth eruption has been reported in premature infants 13,16 with small gestational age and low birth weight and in those with systemic disorders, such as hypothyroidism 17 , while accelerated tooth eruption has been observed in children whose mothers smoked during pregnancy 7,8 as well as in those with childhood obesity 18 and diabetes mellitus 19 .…”

“…Although several studies have examined the factors influencing tooth eruption, their results are inconsistent 8,14,20–22 . Most of the studies focused only on factors within a defined period of time and based their findings on evidence from small cohorts, while some studies focused on the whole pregnancy.…”

We recruited 1296 mothers in their first trimester from the Affiliated Obstetrics and Gynecology Hospital of Nanjing Medical University between May 2014 and September 2015 to investigate the associations of maternal, perinatal and postnatal factors with the eruption timing of the first primary tooth (ETFPT) in a Chinese population. We collected maternal demographic information and clinical data during the perinatal and postnatal period, and oral examinations of the infants were performed by a doctor at 6, 9 and 12 months of age. Multiple regression analysis was used to identify significant explanatory variables for ETFPT. The mean age at eruption of the first primary tooth for all the infants was 6.82 ± 1.90 months. After adjustment for confounders, higher maternal childbearing age (β = 0.57; 95%CI = 0.13–1.02), female sex (β = 0.26; 95%CI = 0.07–0.52), and low birth weight (β = 0.98; 95%CI = 0.20–1.76) were significantly associated with delayed eruption of the first primary tooth, while macrosomia (β = −0.79; 95%CI = −1.30–−0.28) was significantly associated with earlier eruption of the first primary tooth. Maternal childbearing age, infant sex and infant birth weight were significant determinants of ETFPT.

“…The time of formation, calcification and eruption of deciduous teeth is subject to individual differences [13] and is genetically influenced [14,15], and can be affected by several other factors such as sex, ethnicity, birth weight and length, nutritional status, socioeconomic status [16] and congenital anomalies [17].…”

Objective: To analyze the chronology of first deciduous tooth eruption in children with microcephaly associated with presumed or confirmed Zika virus. Material and Methods: A longitudinal study was developed with 74 children of both sexes. Data on prematurity, gestational age (in weeks), anthropometric characteristics at birth [length (cm), weight (g) and cephalic perimeter (cm)] and dental eruption (chronological age and corrected age for prematurity in months) were collected and presented through descriptive statistics. Data was analyzed using the Statistical Package for Social Sciences. Results: The majority of children were female (54.1%) and 14.9% were born premature. The mean gestational age was 38.2 (± 1.9) weeks, while length, weight and cephalic perimeter at birth were 45.6 (± 3.1) cm, 2750 (± 526.6) and 30 (± 2.3) cm, respectively. The eruption of the first tooth occurred on average at 12.3 (± 3.0) months of chronological age and at 11.1 (± 2.3) months of corrected age. The first erupted teeth were the lower deciduous central incisors (82.4%). The mean age for dental eruption in males was 12.5 months (± 3.0) and in females 12.0 months (± 3.1) among full-term children. For premature infants, the mean corrected age of dental eruption was 11.5 months (± 3.4) for boys and 11 months (± 1.7) for girls. Conclusion: In this group of children with microcephaly, the first tooth to erupt was the lower central incisor around the first year of life. Girls had lower average eruption time when compared to boys in both chronological age and age corrected for prematurity.

Relationship between pre-natal factors, the perinatal environment, motor development in the first year of life and the timing of first deciduous tooth emergence

Abstract: An earlier onset of tooth emergence in children exposed to maternal smoking during pregnancy seems to provide further evidence for disturbed foetal development in a smoke-induced hypoxic environment.
