Interrelations Between Odonto-Parodontal Affects of the First Permanent Molar and their Odontogenetic and Morfostructural Peculiarities

The permanent first molar is the first tooth in the permanent series that erupts into the archway and thus transforms the temporary dental arcade into mixed arcade, being the only stable element throughout the mixed dentition. The plurivalent importance of the permanent molar must be considered permanently in the harmonious development of the dento apparatus. This tooth has a determining role in dental arcade functionality, being the oldest witness of the permanent occlusion. The permanent first molar is a guardian of the occlusal memory and contributes to the agreement of the predetermined with the posterior one (the temporo-mandibular joint). The first permanent molar improves the relationships in the vertical plane, the early loss of it generates morphological and functional disorders which takes place cascaded across the arcade, and its extraction must be considered a personal failure of the dentist. The study consists of 80 patients divided into two groups; the group I consists of 45 children with chronological ages ranged between 5-6.6 years; the second group selected from dental care, a total of 35 children aged between 8.6-10 years. Dental caries morbidity has increased significantly over time and surprised by age the younger becoming a true social scourge. The current pediatric dentistry emphasizes new aspects of the normal and pathological growth of the dento-maxillary apparatus and underlines the special significance of the morpho-structural and functional integrity of the odontous units in close correlation with the subsequent development of the dento-maxillary apparatus in general.
