The ectopic eruption of the maxillary first permanent molar (EEM) is a local alteration of dental eruption with a multifactorial aetiology. The aims of our study were to determine the prevalence of the EEM in children and to analyse whether there is a relationship between EEM and dento-skeletal characteristics. A total of 322 children were analysed with the Ricketts cephalometric study and descriptive and analytical statistical analysis was carried out. The prevalence of EEM was 8.7%, with no statistically significant differences regarding gender or location, but a higher prevalence in the 7-year-old age group (18.8%) and bilateral EEM was more prevalent than unilateral EEM (p < 0.05). The most frequent findings were a shortened anterior cranial base, a retroposition of the maxilla and a distal position of the upper permanent first molar in relation to the pterygoid vertical in children with EEM. No statistically significant differences were found regarding the cephalometric parameters except a decreased palatal plane in the bilateral EEM group and a distal upper incisor position in the EEM group (p < 0.05). In conclusion, the prevalence of the EEM was 8.7%, more frequently bilateral, and significantly in seven-year-old patients. Children with bilateral EEM have decreased palatal plane values and a more posterior position of the upper incisor.

Objective: To evaluate the mesial-distal positioning of the maxillary first permanent molar in children who present with ectopic eruption of the maxillary first permanent molar (PFMEE).  Methods: panoramic radiographs and lateral cephalometric radiographs 12 children of both genders were evaluated. The study group was composed of 12 children with PFMEE and the control group was composed of 12 children with normal occlusion with the first upper permanent molar in occlusion. After selecting the exams from both groups and performing the anatomical tracings, linear and angular measurements were performed. In the lateral cephalometric radiographs the following angles were evaluated: SNGo.GN, SN.GN, SNA, SNB, ANB, 6mx.Palatal Plane and the 6mx.PTV distance. In the panoramic radiograph the angles 6mx.Infraorbital Plane and 6mx.Occlusal Plane were evaluated. Results: PFMEE can occur in individuals regardless of their skeletal pattern. The control group showed much greater angular measurements 6mx.Palatal Plane and 6mx.Infraorbital Plane. Conclusion: There is no relationship between PFMEE and craniofacial growth pattern, there is no direct relationship with the anteroposterior relationship of the apical bases and in cases of PFMEE the mesial angulation is reduced, representing lack of space for eruption of the first permanent molars.

Rule Out

Treatment is advised to guide the tooth into a more favorable path of eruption to minimize damage to affected dentition, preserve arch length, and to maintain function. Without intervention, sequelae can include premature loss of the anteriorly affected tooth, tipping and rotation of the ectopic molar, space loss and malocclusion. Treatment will depend upon the severity of the impaction. Mildly to moderately impacted molars can be guided easily with elastic orthodontic separators. More severe impactions require more complex treatment options, including potential extraction of the anteriorly affected tooth, removable or fixed appliances, or surgical uprighting. The present study was planned for evaluation of Evaluation of Ectopic Eruption in Teeth’s of Childrens from 5 to 12 Years Age Group. The present study was planned in Department of Orthodontics, Patna Dental College and Hospital, Patna. Total 50 childrens referred to Department of Orthodontics were evaluated for the ectopic eruptions. All the radiographs were compared in each patient, along all the usual followup time. To rule out the possibility of error due to radiographic magnification, the crown measurements in bitewing radiographs and in dental casts were compared, and no significant differences were present. Early intervention of ectopically erupting first permanent molars is very crucial to avoid complex orthodontic treatment later on. Ectopic eruption of individual teeth tend to occur as often bilaterally as unilaterally in the same arch, except for mandibular central incisors, first molars and mandibular canines. Early diagnosis and interception of ectopically erupting teeth will allow us in preventing more complicated malocclusions in future.
