Tooth development represents a unique and temporal series of events; in which the dental follicle is an ectomesenchymal tissue that surrounds the developing tooth germ preceding its eruption. This tissue is thought to contain stem cells, and lineage-committed progenitor cells form cementoblasts, periodontal ligament cells and osteoblasts (Morsczeck et al. 2005).

Scientific age assessment is a part of legal science continually advancing because of the rising quantities of asylum seekers lacking substantial individuality papers. This issue is especially important on account of youths and youthful grown-ups engaged with common and criminal methodology or looking for refuge. In these cases, it is vital to utilize age-assessment strategies which permit the operators to decide as precisely as conceivable the legitimately applicable ages which change as indicated by the public. There are three measures used for assessing the age:Actual assessment is done through recognition of anthropometric estimations (mass, stature, constitution), indications of erotic development examination, ID of improvement infections;Bone age assessment for the subject is not shown up effectively since at the age of 17 the bones get fused and also through the clavicle bone, assessment of age is not evaluated due to the hardening part of epiphysis bone. Based on the above-given fact, these are not explicitly suggested.Dental assessment can be done by dentist based on the tooth development and testing the condition of dentition using X-ray.Numerous approaches of DA assessment were planned by many investigators for developing folks. In the above-mentioned approaches, radiographs were used as evidence to analyze the progressive sequence of teeth development, and each stage of development was coded and scored. These scores were manipulated meticulously to derive the DA of an individual and compared by their CA, with acceptable error limits. However, all these methods dated back a few decades and the change in the growth trend of the current generation alarmed for formulating a newer method of DA assessment.

The very high frequency of LEH (85.7%) in the sample is indicative of physiological stress during tooth development. There are few comparative data from post-medieval period England, however the lower status ‘earth cut graves’ from St Martins, Birmingham had a similar high prevalence (73.5%) compared with higher status ‘vault burials’ (47%) (Brickley and Buteux 2006). All of the adults with appropriate dentition (n = 7) from SJM have been isotopically identified as non-local, and thus are likely first generation colonists to New Zealand (King et al. 2020). As these episodes of stress occurred during childhood, they represent periods of stress at ‘home’ rather than in the colony and suggest that affected individuals were of a working-class background.
