Combined surgical and orthodontic treatment of impacted second lower premolar – Case report

Summary Impacted tooth is a tooth that has failed to reach occlusal plane, with 2/3 of completed root growth. There are various reasons for teeth impaction, however, lack of space for its emergence is considered to be the main reason. The most commonly impacted teeth are lower wisdom teeth, then upper wisdom teeth, upper canines, and less frequently lower premolars. There are only few studies that have addressed the issue of impacted lower premolars, their etiology, prevalence and treatment. The patient (22 years old) visited orthodontst for the lower jaw aesthetic teeth corrections, due to crowding. Ortopantomography analysis revealed impacted lower right second premolar that caused resorption of mesial root of the first molar. The treatment plan included tooth #46 extraction and placing orthodontic brackets on the impacted second premolar. The next step was extrusion of the tooth #45, its introduction to occlusal plane and orthodontic treatment resumption. Orthodontic treatment of impacted teeth with fixed orthodontic appliance provides excellent therapeutic results. The treatment success depends primarily on adequate planning, cooperation and joint work of oral surgery and orthodontic specialists.

Prevalence of Impacted Teeth among Young Adults: A Retrospective Radiographic Study

Objectives: The prevalence of impacted teeth fluctuates across various ethnicities and geographical regions. The aim of the present study was to evaluate the prevalence and patterns of impacted teeth among patients living in the central part of Iran. Methods: This retrospective study was conducted on 3632 patients within the age group of 17-30 years. The frequency and pattern of the impaction were determined using orthopantomogram (OPG). Results: According to the results of the study, 56.3% of the patients were female (n=2046). Out of the 3632 OPGs, 1602 cases (44.1%) were detected with at least one impacted tooth. No significant difference was observed between the males (n=682; 42.6%) and females (n=920; 57.4%) in this regard (P=0.237). Furthermore, the third molars were the most common impacted teeth found in 1156 radiographs (31.8%) with no significant difference between the males (n=358; 30%) and females (n=798; 70%) (P=0.386). Mesioangular and distoangular impactions were detected to be the most frequent angulation of the impacted third molars in the mandible (49%) and maxilla (41%), respectively. Additionally, 357 (9.8%) and 78 (2.1%) cases showed at least one impacted maxillary canine and one impacted mandibular second premolar, respectively. Moreover, impacted ectopic teeth were observed in 11 (0.3%) individuals. Conclusion: Based on the findings of the present study, the third molar was the most common impacted tooth observed in the people living in the central region of Iran, followed by canine and second premolar impaction. The prevalence of the third molar impaction in the females was nearly twice as much as that in the males.

Intra-Osseous Migration of Second Lower Premolar-Literature Review and a Case Report

Migration is a kind of eruption abnormality where a tooth is grown far from its original site of development. The incidence of mandibular second premolar impaction has been estimated to be 2.1% to 2.7%. The frequency of its intra-osseous distal migration is 0.25%.We report a case of extremely distally intra-osseous migration of mandibular second premolar which was found in routine radiography. A 28-year-old woman who attended at dental clinic to treat teeth caries was noticed to have her lower second premolar located horizontally in the homolateral mandibular angle below the inferior alveolar nerve canal on panoramic view. As the patient was asymptomatic, she was advised to take follow-up radiographs to rule out any cystic/neoplastic changes. Taking panoramic radiograph in patients with missing mandibular premolars should be considered, because in rare cases migration or transmigration of these teeth may happen.

A Retrospective Panoramic Radiographic Study on Prevalence of Impacted Teeth in South Karnataka Population

Objective: The present panoramic radiographic study was done to investigate the prevalence of impacted teeth excluding third molars in South Karnataka population. Materials and methods: This retrospective study evaluated 1050 panoramic radiographs of patients of South Karnataka population who reported to the Department of Oral Medicine and Radiology, K.V.G. Dental College, Sullia. Panoramic radiographs were examined for the presence of impacted teeth including the supernumerary teeth. Results: At least one impacted teeth was noted in 4.8% of patients. Most common impacted teeth in our study were maxillary canines (2.66%), followed by impacted supernumerary teeth (1.42%). The incidence of impacted premolars and incisor were comparatively lower (0.85% and 0.28% respectively). Conclusion: Impaction is a common dental anomaly, though the incidence can vary in different population. Knowledge about the prevalence can be helpful in treatment aspect and can be used as a valuable forensic tool.

NEED OF PREVENTION STEPS AGAINST IMPACTION OF MANDIBULAR AND MAXILLARY PREMOLARS

Lower second premolars, closely followed by upper premolars, are regarded as the third most common teeth prone to impaction, after wisdom teeth and upper canines. Objective of this article is to show the possibility for spontaneous eruption of impacted premolars upon extraction of deciduous molars and removal of the follicular cyst as described in several clinical cases. The present paper reports four clinical cases supporting the thesis that regardless of the reason behind impacted premolars, undertaking preventive measures significantly improves the position of the germ of those teeth. Conclusions: The early extraction of the deciduous molar, monitoring the patient and reserving the space for the succeeding impacted premolar can lead to non-invasive or relatively short orthodontic treatment (secondary prevention).If root development is incomplete yet there is a good growth potential which could lead to spontaneous eruption (primary prevention). Age specifics particular to children such as the great regenerative abilities of the bone, provide a good prognosis for spontaneous eruption or significant improvement in the position of impacted premolars and facilitate the orthodontic treatment.

Contemporaneous Impaction of Primary Maxillary Second Molar and Its Succedaneous Tooth - A Rare Occurrence

ABSTRACT A tooth is considered impacted when it has failed to fully erupt into the oral cavity within its expected developmental time period and can no longer reasonably be expected to do so. The prevalence of impacted premolars has been found to vary according to age. Submergence is a term defining a tooth that remains below the occlusal plane. Dental ankylosis is thought to be major etiological mechanism of submergence. Early detection and intervention of any impacted tooth must be done either surgical or orthodontically else it may lead to sequelae of malocclusion

The Prevalence of Impacted Premolars in the Anatolian Population

Objective: The aim of this study was to determine the prevalence of impacted premolars and the associated pathology of these teeth in the Anatolian population. Methods: This retrospective cohort study was composed of 10246 panoramic radiographs of patients (6074 females, 4172 males) between 2000 and 2011. We reviewed the panoramic radiographs and clinical data and determined the prevalence of impacted premolars to be associated with sex, age, and number of premolars. We investigated the associated pathology and approach of treatment. Results: A total of 83 patients (43 females, 40 males; mean age 23.42±11.18 years, range 12 to 69) had 101 impacted permanent premolars that were either mesioangular (n=47, 46.54%), vertical (n=32, 31.68%9), distoangular (n=14, 13.86%), horizontal (n=6, 5.94%), and/or buccolingual (n=2, 1.98%). Premolar transmigration was absent. Of these premolars, 7 (6.93%) were associated with cystic lesions. In this study, 61.39% of impacted premolars were extracted; 39 (38.61%) were followed up. Conclusion: The prevalence of impacted premolars in the Anatolian population was determined to be 0.98%. Although premolar impaction is infrequent, early diagnosis is important because most of the cases (93.07%) are asymptomatic.

Prevalence of impacted premolar in Iraqi sample

Background: The most commonly impacted teeth are the third molars, maxillary canines, maxillary central incisors and premolars. Impacted premolars may lead to aesthetic concerns, masticatory inefficiency and oral hygiene difficulties as well as follicle pathology and destruction of adjacent structures, including neighboring teeth, the purpose of this study to shade light on the prevalence of impacted premolar in Iraqi sample. Subject, materials and method: Retrospective and protrospective studies invoved 2000 OPG examined by radiologist for age ranged between 15-55 years to indicate the prevelance of impacted premolar, uni or bilateral impaction, migration of impacted premolar and its association with pathology. Result: From 2000 OPG 99 patient with( 101 impacted premolar), 2 (204.%) bilateral and 97 (97.97%) unilateral, prevelance of upper 1st and 2nd premolar was (2.97%) and (5.94%) respectively, while for lower 1st and 2nd premolar was (11.88%) and (79.20%) respectively. From all impacted premolars only (2.97%) associated with pathology and (o.99%) migrated teeth. Conclusion: The most prominent one of premolars was lower 2nd premolar and the latest one was1st upper premolar, migrated teeth was very rare and the pathology associated with (2.97%) only. The causes related with impaction in this study retaind first decediouce molar and not enough space for eruption

Prevalence of impacted and supernumerary teeth in the North Indian population.

Objectives: Dental impaction is a very frequent problem. Supernumerary teeth, or hyperdontia, are the presence of additional teeth to the normal series in the either of the dentition. The presence of impacted and/or supernumerary teeth can cause various complications. The objective of the present study was to determine the prevalence of impacted and supernumerary teeth in the North Indian population. Study Design: The panoramic radiographic records of 4750 patients attending the Department of Oral Medicine and Radiology, Jodhpur Dental College General Hospital between September 2008 to December 2012 were examined for this retrospective study. The ages of the patients ranged from 8 to 72 years, with a mean of 34.6 years. Results: A total of 798 (16.8%) patients presented with 1126 impacted teeth. Impacted canines were the most prevalent (9.7%), followed by impacted premolars (4.3%). Supernumerary teeth (1.6%) and impacted molars (1.2%) were less prevalent. Among the 842 impacted teeth, the most frequently affected teeth were the canines (56.7%), followed by premolars (27.8%), and supernumerary teeth (9.3%), while the prevalence of impacted molars was quite lower (6.2%). Conclusion: The most frequently impacted teeth were maxillary canines and the mesiodens were the most common supernumerary tooth. The early diagnosis of supernumerary and impacted teeth is essential to prevent malocclusion and malalignment of permanent teeth demonstrating the importance of panoramic radiographs in their detection. Key words:Impacted, supernumerary, prevalence, canines, mesiodens.

Asymptomatic Impacted Supernumerary Maxillary Parapremolar

ABSTRACT A case of unilateral impacted supernumerary premolar has been reported. Supernumerary premolars are usually asymptomatic and most cases are diagnosed by a chance during inspection of radiographs.

Management of Impacted 2nd Premolar Impaction by Buccal Approach: A Case Report

This case report presents treatment of a distally impacted mandibular 2nd premolar having a 90° tilt to the long axis of the tooth. In this 16 year old girl radiological finding described that horizontally impacted mandibular second premolar was positioned below the roots of the mandibular first molar. Due to the abnormal position of impacted premolar, it was planned to be removed surgically. Finally, the horizontally impacted mandibular second premolar was extracted without any injury to the mental nerve.

Unicystic ameloblastoma associated with impacted supernumerary premolar: An unusual case report

Dental literature is replete with cases of supernumerary mandibular premolar and unicystic ameloblastoma as separate entities but to our knowledge the present clinical scenario of unicystic ameloblastoma associated with impacted supernumerary premolar was rarely reported. The purpose of this article is to report a patient who presented with pain and swelling of the left mandible of five months' duration. Following clinical evaluation and radiological examination a diagnosis of a rare case of mandibular supernumerary premolar associated with unicystic ameloblastoma was made. The tumor was excised and mandibular reconstruction done.

Isolated bilateral macrodontia of mandibular second premolars: A case report

Isolated bilateral macrodontia of mandibular second premolars is an extremely rare dental anomaly with only 5 cases reported to date. This case report presents clinical and radiographic findings of isolated bilateral macrodontia in a 12-year-old child. The patient was referred to the clinic with local crowding of mandibular posterior teeth. Radiographic findings revealed the presence of impacted macrodont mandibular second premolars and their distinct morphological appearance, characterized by large, multitubercular, molariform crowns, and tapering, single roots. Following surgical removal of the impacted premolars, orthodontic therapy was initiated to correct the malocclusion. Along with the features and treatment of this rare anomaly, this case report also illustrates the benefits, in terms of treatment planning and surgical technique, of supplementing conventional radiography with cone-beam computed tomography to localize the macrodont premolars and accurately establish their relationship with the neighboring roots and anatomic structures.

Patient with nonsyndromic bilateral and multiple impacted teeth and dentigerous cysts

This article reports the successful treatment of a patient with the unusual occurrence of bilateral and multiple dentigerous cysts of the premolars. One impacted mandibular premolar was moved by traction orthodontically. On the opposite side, the impacted premolar was autotransplanted after space was created through mesial movement and hemi-sectioning of the neighboring molars. The impacted maxillary premolar was extracted. Miniscrews were additionally used for anchorage reinforcement to prevent unintended counteractions and solve the problem of space management after autotransplantation. We also reviewed the clinical implications of the diagnosis, planning, and treatment of cyst-associated impacted teeth in young adult patients.

Fused Double Supernumerary Premolars of the Mandible: A Rare Case

The incidence of nonsyndromic supernumerary premolars is rare. Supernumerary premolars are likely to undergo pathological changes. The most commonly encountered complications with these teeth are dentigerous cyst and root resorption of the adjacent tooth. This paper is about impacted double fused supernumerary premolars in the right mandiblular body associated with an impacted first premolar in a 17-year-old male. Under local anesthesia, the supernumerary premolars and the impacted permanent first premolar were surgically removed. Early diagnosis followed by an appropriate treatment at the right time will result in favorable prognosis in such cases.

Autotransplantation of an ectopic impacted premolar with sinus lift and allogenic bone graft

This article presents a case report of autogenous tooth transplantation to a site which had insufficient bone volume using a sinus lift and allogenic bone graft. An ectopic, fully impacted premolar tooth was autotransplanted from its ectopic impaction site into its original site, where there was insufficient recipient vertical bone volume because of sinus expansion. The deciduous tooth was extracted from the recipient site, and the sinus membrane detached and elevated via the alveolar socket. Allogenic bone grafting was performed, and the impacted premolar was transplanted into the prepared site. To improve adaptation, the recipient site was prepared using a rapid prototype tooth model, a replica tooth which allowed complete socket preparation in advanced of the actual removal of the donor tooth. The donor tooth was fixed with sutures and maintained for 17 days to allow physiologic movement. Root canal treatment was initiated 24 days after autotransplantation, and an intra-canal medicament was used for 4 months. Canal filling was completed 5 months after autotransplantation. There was no root resorption of the transplanted tooth, and the grafted bone was well preserved and had no signs of infection. When the recipient bone volume is insufficient, autotransplantation can be preceded by bony augmentation. The preparation of the recipient tooth socket using a tooth replica from CBCT reduces the extra-oral time of the actual tooth and promotes better periodontal ligament healing. Careful evaluation of the pulp status of the donor tooth is important in advance of timely endodontic treatment.
