Dental Caries is an irreversible microbial disease of the calcified tissues of the teeth, characterized by de-mineralization of the inorganic portion and destruction of the organic substance of the tooth.
Both Primary and permanent teeth are susceptible to caries. And we are going to see the decreasing order in which teeth are affected with caries separately in both Primary and Permanent dentition.
Caries Susceptibility in primary and permenant teeth
Caries Susceptibility of Primary Teeth in Descending order from most affected to least affected tooth:
2nd Molar > 1st Molar > Canine > Lateral Incisor > Central Incisor
Both Maxillary and Mandibular teeth have the same incidence of caries susceptibility sequence in primary teeth.
Caries Susceptibility of Permanent Teeth in Descending order from most affected to least affected tooth:
1st Molar > 2nd Molar > Maxillary 2nd Pre Molar > Maxillary 1st Pre Molar & Mandibular 2nd Pre Molar > Maxillary Central & Lateral Incisor > Maxillary Canine & Mandibular 1st Pre Molar > Mandibular Central & Lateral Incisor > Mandibular Canine
