first and second premolars answer mandibualr will contact maxillary 1molar in rest positon as it glide in forward it will go from center of molar to second premolar.

second premolar and 1 molar

q] third pair of permanent teeth to erupt in normal sequence ?
max central incisors
max laterals
mand laterals [ans given ]this is right ,first 1 molars ,2 man central then mand laterals and max centrals eruptmost cases mandibualr teeth have tendency to erupt first,(we will see in most children)
mand canines

Is it Creatinine, because creatinine is freely filtered,not reabsorbed & a small amount is secreted also...?
