DIFFERENCES between the Primary & Permanent teeth

A – size :1) Primary teeth as smaller in all dimension than permanent teeth2) The mesiodistal width of primary incisors is less than their permanent3) The thickness of enamel and dentine in primary teeth is approximately half its thickness in permanent teeth

B – coluor :the colour of primary teeth is bluish white , while that of permanent teeth ranges from grayish white to yellowish whiteC - crown :the crown of primary teeth are wider in their mesiodistaldiameter in relation to their cervico _occulusal height than those of permanent teeth.This given the primary anterior teeth a cupshappedappearance

According to the World Health Organization (WHO), Malnutrition is a major health concern and the most common cause of growth failure in children .

Delayed eruption of anterior maxillary incisor was detected in 14.6 % of cases . [Table 1]

D E is more common on Male (16.4%) than Female (9.5%) . [Table 2]

D E in age 8 year was detected in 11 % of cases . [Table 3]

D E in age 9 year was detected in 18 % of cases . [Table 3]

D E in age 10 year was detected in 14 % of cases . [Table 3]

9 year old is More Age detected D E (45 %) than 8 and 10 year old . [Table 3]

8 year old is Less Age detected D E (22.6 %) than 9 and 10 year old . [Table 3]

Both Medical and Dental causes was more recorded 52 %than only one of them . [Table 4]

Delayed eruption of Lateral incisor 55 % was more than Central incisor . [Table 5]

Private school student is less effected of D E 13 % than Govermental school student 16 % . [Table 6]

That is very Important for parents to realize the eruption time of teeth and monitoring them and avoid any early or delayed extraction of teeth .

Malnutrition (specially in yemen) is the Major causes of growth failure , subsequently that important to raise Economic level for people .

Early detection for eruption problems avoids a lot of dental complication and money losses . This is achieved by maintain a regular visits to dentist .

The research talk about delayed eruption of anterior maxillary incisor on range age between 8 – 10 years

It covered 212 students of two primary schools . We adopted in our diagnosis on clinical feature and

history . The result was that there is high percent of delayed

eruption due to improper nutrition which widely observed .
