“…Recently, we have reported the results in a part of CPP series on child's tooth effects as a consequence of maternal smoking in pregnancy as well as the effects of prematurity, showing metric size variation in deciduous and permanent dentition and the accelerated eruption of some teeth (permanent incisors and first molars) and labio‐lingually (L‐L) ‘thin’ permanent mandibular incisors in the cases of early delay of overall motor development. These results were in line with the earlier medical assumptions that the critical period in maternal smoking occurs during the latter half of the pregnancy and premature infants are sensitive to have variation in some tooth dimensions and lateralities, but differential results according to sex and race could be a consequence of differential buffering capacity/body volume during critical period of the pregnancy (11,14). This is also another challenge to future studies in the etiology of craniofacial/dental asymmetries.…”

“…Such a framework provides a valuable basis for clinical diagnosis, treatment planning and counselling. Apart from the value to the clinician of appreciating that there are links between tooth size, shape and number within the dentition, reflecting underlying developmental processes, there are many other dental phenotypes that have been shown to be associated with congenitally missing teeth 94 . These include delayed formation and eruption of other teeth, malposition and ectopic eruption of teeth, taurodontism, rotation of teeth, short roots and simplified morphology 95–101 .…”

This paper reviews the concept of morphogenetic fields within the dentition that was first proposed by Butler (Butler PM. Studies of the mammalian dentition. Differentiation of the post-canine dentition. Proc Zool Soc Lond B 1939;109:1–36), then adapted for the human dentition by Dahlberg (Dahlberg AA. The changing dentition of man. J Am Dent Assoc 1945;32:676–90; Dahlberg AA. The dentition of the American Indian. In: Laughlin WS, editor. The Physical Anthropology of the American Indian. New York: Viking Fund Inc.; 1951. p. 138–76). The clone theory of dental development, proposed by Osborn (Osborn JW. Morphogenetic gradients: fields versus clones. In: Butler PM, Joysey KA, editors Development, function and evolution of teeth. London: Academic Press, 1978. p. 171–201), is then considered before these two important concepts are interpreted in the light of recent findings from molecular, cellular, genetic and theoretical and anthropological investigation. Sharpe (Sharpe PT. Homeobox genes and orofacial development. Connect Tissue Res 1995;32:17–25) put forward the concept of an odontogenic homeobox code to explain how different tooth classes are initiated in different parts of the oral cavity in response to molecular cues and the expression of specific groups of homeobox genes. Recently, Mitsiadis and Smith (Mitsiadis TA, Smith MM. How do genes make teeth to order through development? J Exp Zool (Mol Dev Evol) 2006; 306B:177–82.) proposed that the field, clone and homeobox code models could all be incorporated into a single model to explain dental patterning. We agree that these three models should be viewed as complementary rather than contradictory and propose that this unifying view can be extended into the clinical setting using findings on dental patterning in individuals with missing and extra teeth. The proposals are compatible with the unifying aetiological model developed by Brook (Brook AH. A unifying aetiological explanation for anomalies of tooth number and size. Archs Oral Biol 1984;29:373–78) based on human epidemiological and clinical findings. Indeed, this new synthesis can provide a sound foundation for clinical diagnosis, counselling and management of patients with various anomalies of dental development as well as suggesting hypotheses for future studies.

“…While the association between low birth weight and hypoplastic enamel appears to be supported in the literature, Harila-Kaera et al [2003] found that short gestation was not associated with reduced deciduous or permanent [Harila-Kaera et al, 2001] crown size. This suggests that the effect of low birth weight on enamel development, if it does exist, is not universal.…”

Is There an Association between Low Birth Weight and Caries in the Primary Dentition?

Objectives: An association between low birth weight and caries in the primary dentition has been suggested but not demonstrated. This study analyzed this association using data from a probability sample of US children 2–6 years of age. Methods: Data from the Third National Health and Nutrition Examination Survey (NHANES III) were used. Variables included decayed and filled primary surfaces (dfs), birth weight, gestational age, and Apgar score (a surrogate measure of fetal well-being); maternal age, education, income; number of previous births, marital status, the existence of pregnancy complications, and cigarette smoking during the pregnancy. Data were analyzed using SUDAAN 8.0.2. Results: Bivariate Poisson regression showed that children of mothers who were unmarried (incidence density ratio, IDR = 3.28), with less education (IDR = 1.43), who were 17 years of age or younger at birth (IDR = 1.51), and had 2 or fewer prenatal visits (IDR = 1.65) had a significantly ( p <0.05) greater risk of caries than the reference groups. Children of mothers with pregnancy-related hypertension (IDR = 0.14) had less than 20% the risk of caries than the reference group. Blacks (IDR = 1.37) and Mexican-Americans (IDR = 2.38) had greater risk of caries than whites, and children of low (IDR = 2.57) and middle income (IDR = 2.00) level families had higher caries risks than those of upper income families. Multivariate Poisson regression found only race-ethnicity, age, and income level to be statistically significant. Conclusions: This study did not support the association between low birth weight and caries of the primary dentition.
