Longitudinal study of age and order of eruption of primary teeth in Indian children

Abstract

Objective: To determine the chronological eruption parameters of primary teeth in Indian children. Study Design: A longitudinal study consisting of 135 healthy children (74 boys and 61 girls) attending three child health centres in the city of Hyderabad, India were randomly selected and followed from the emergence of the first to the last tooth. Ages and order of tooth eruption were studied for both genders. Results: Boys showed tendency towards earlier eruption for all teeth except maxillary second molar and maxillary/mandibular first molars which erupted earlier in girls. Comparison between maxillary and mandibular showed a tendency to earlier mandibular eruption of central incisors, lateral incisors and second molars in both genders. Conclusions: Within the limitations of this study, a baseline data and chronological table for eruption of primary teeth among Indian children has been established. Indian children experienced delayed eruption of primary teeth when compared to their counterparts in other populations.

Polymorphism in emergence of deciduous dentition: A cross‐sectional study of Indian children

“…The Indian population is made up of many races and ethnicities. Similar findings have been reported by GunaShekhar and Tenny, who found that boys had earlier eruption compared to girls, and the study population experienced delayed eruption of primary teeth when compared to their counterparts in other populations . Because the Indian population is multiethnic in nature, the result warrants the need for a study to be conducted on a larger scale, controlling for the effect of different ethnic backgrounds and socioeconomic conditions.…”

Time and Eruption Sequence of Permanent Teeth in Hyderabad Children: A Descriptive Cross-sectional Study

“…Very few studies were carried out in the past on the eruption time of teeth in the Indian population. 5 - 8 The studies done by Tendon 9 and Gunashekhar and Tenny 8 showed differences in the eruption of deciduous dentition, and the study done by Gupta et al 10 showed differences in the eruption of permanent dentition in a south Indian population as compared with the data given by Logan and Kronfeld 4 that was based on Western population. These findings strongly suggest that racial differences between the two populations is the main factor underlying the variations in eruption timings.…”

Low birth weight and the delay on the eruption of deciduous teething in children

“…The catch-up weight growth is the compensatory weight gain and above normal standards for specific age between birth and 24 months. Considering the catch up and the delay in the dental eruption in children with low birth weight is even more evident until 24 months of age, 11,29 opting to control the child's covariate age, even if the child did not behave as a modifier effect in the analysis. Higher magnitude of positive associations were found among children aged up to 24 months.…”

“…[1][2][3][4][5][6][7][8][9] The knowledge on the normal timing of tooth eruption ranges from the intrauterine life up to 30 months, it has clinical relevance to diagnose various locations and systemic conditions that may affect this process. [1][2]4,6,[9][10][11][12][13][14][15][16][17] The variation in the chronological dental eruption is dependent of multiple genetic and environmental factors and none of them acts individually, there is an inter-relation among themselves during the development of deciduous teething, such as race, gender, systemic conditions, environmental conditions, socioeconomic level, maternal breastfeeding, infant nutritional status and physical development. 1,18 Nutritional factors influence the odontogenesis and the eruption of the teeth.…”
