“…According to these studies, the population examined by us, in 96% of the cases, falls into the fifth category. Therefore, in patients who had the FPM extracted before the eruption of the second permanent molar, it is very important with regards to the patients' comfort and health to review the patient regularly and to determine any need for orthodontic treatment [12].…”

Objective: The purpose of the present study is to evaluate the disintegration of the contact point system, the occlusal changes, and the masticatory force following the loss of the first permanent molars (FPM).Material and methods: Clinical examinations were performed among 8-18-year-olds following the changes in the contact points and their effects on the dento-maxillary apparatus. The sample comprises 422 individuals, 220 girls and 202 boys. The occlusal masticatory force was measured using the T-Scan in the case of the opening of contact points. For the statistical data analysis, was used correlation and Chi Square Test in the GraphPad InStat program.Results: A very weak reverse dependence was found between the size of the edentulous space and the deflection of the upper and lower interincisal lines (r=-0.02) and between the age and size of the edentulous space (r=-0.05). There is a statistically significant chance of mandibular lateral deviation by dental migration following edentulism (p=0.043). In the case of the opening of contact points, there are 1.42 times higher risks of modified sagital relationship in the molar segment (p=0.016) and 2.7 times greater risks of the tipping of the neighbouring teeth (p=0.021). Following the evaluation of the T-Scan measurements, we found in each case a significant decrease in the masticatory force in the edentulous area and the opening of the interproximal contact points.Conclusion: Based on the obtained results, we can state that the opening of contact points decisively influences the stability of the occlusion and the size of the masticatory force.

“…12 Extraction at ideal time or early extraction are mostly mentioned in literature. 1,9,13,18,24,34 There are very few clinical studies about late extractions. 12 It has been reported that late extractions in the mandible will cause cross-bite and nonworking side conflicts with the mesiolingual tipping of the PSM tooth, the second premolars to tip distally, and the development of periodontal diseases and alveolar bone atrophy due to poor contact relations between the PSM and the second premolars.…”

Objectives: Before they haven't completed its development, permanent first molar (PFM) teeth which have been decayed and treated with root canal therapy is mostly extracted before the child even reaches adult hood. With correct evaluation of patient, these extracted teeth's space can be ideally closed by permanent second molars (PSM). The aim of the study is to learn under which conditions we can provide ideal closure and occlusion in patients who refer to us in a late stage. Materials and Methods: 695 patients aged 6-16 years who had PFM tooth extracted at a Faculty of Dentistry were retrospectively evaluated from the system. 117 patients had their PFM tooth extracted after the ideal age range and 15 of them were found to meet the inclusion criteria. Panoramic films of 21 teeth of 15 patients with spontaneous ideal closure were evaluated before extraction and after eruption of PSM teeth. The contact between the PSM and the second premolar was recorded and intraoral photographs were taken.Rotations in the PSM and second premolars, axis disturbances towards the lingual/buccal, midline deviations in both jaws, TMJ dysfunctions and chewing habits were evaluated.Results: When PFM extraction was performed, PSM development stage was determined as Demirjian G in 19 teeth and H stage in 2 teeth. Tipping was observed in 80%, and rotation in 9.5% of the PSM teeth. Clinically, it has been determined that 85% of the patients don't notice the PFM deficiency, don't complain about their teeth and don't consider orthodontic treatment. Conclusions:Within the limits of this study, it has been observed that ideal spontaneous space closure and ideal occlusion can be achieved, although it was extracted in late period. In ideal occlusion, rotation or tipping after extraction in late period; permanent third molar presence and eruption pressure were more effective than the eruption direction and angle of the PSM tooth.
