Oral pain due to severe pre-eruptive intracoronal resorption in permanent tooth

BACKGROUND

Pre-eruptive intracoronal resorption is a dental lesion located within the dentin. This defect is usually discovered incidentally on routine dental radiographs. Occasionally this process may be associated with oral pain in advanced lesions.

CASE REPORT

This case report describes a 12-year-old boy whose chief complaint was a diffuse oral pain due to a severe pre-eruptive intracoronal resorption in a permanent second molar. The previous radiographs, taken at the age of nine years, showed no evidence of the lesion. After surgical exposure, a pulp-like tissue under the crown was removed and analyzed; subsequently the tooth was extracted due to extensive resorption. A follow-up of the unerupted third molar, still in formation process, allowed to see that it was favourably positioned for replacing the extracted molar.

A case report of gingival enlargement associated with invasive cervical resorption

Invasive cervical resorption (ICR) is a rare external dental resorption with unknown etiology; it progresses asymptomatically in the cervical area of the permanent teeth. Lesions are mostly misdiagnosed as internal resorption or caries, which leads to erroneous treatments. This case report presents the clinical and radiological diagnosis, as well as the results of treatment and 3-year follow-up in a 50-year-old female patient with gingival enlargement associated with ICR in tooth No. 25. Granulation tissue was removed by accessing the cervical resorption area through a flap operation. Following the endodontic treatment, the tooth was restored using composite resin and the hyperplastic lesion was excised. In conclusion, it should be kept in mind that clinical, radiological, and pathological evaluation in the differential diagnosis of localized hyperplastic lesions in the gingiva is of importance and that ICR could play a role in the etiology of these lesions.

Unexpected early apical resorption of primary molars and canines

AIM

This was to examine the resorption pattern of primary molars and canines in dentitions with advanced apical resorption even though the permanent successor had barely begun root formation and to verify the resorption process histologically.

STUDY DESIGN

Panoramic or bite-wing radiographs were selected from a dentition archive of radiographs from 142 children with deviant resorption patterns.

METHODS

There were 14 patients (10 boys, 4 girls) aged 6 years 2 months to 8 years 1 month selected. In 11 patients abnormal resorption occurred only in the roots (group I). In 3 patients resorption occurred in the roots as well as in the crown (group II). The degree of resorption was evaluated using Haavikko's five resorption stages, and the degree of development of the permanent successor was evaluated using Haavikko's ten formation stages [Haavikko, 1973]. For histologic study 7 teeth were decalcified, paraffin-embedded, sectioned and stained with hematoxylin and eosin and examined microscopically.

RESULTS

Group I: in 5 patients severe root resorption occurred before crown formation of the permanent successor was completed. In 6 children the abnormal resorption pattern was less severe. Group II: in 3 subjects full resorption of the root complex was observed as well as partial resorption of the crown. A histological analysis confirmed the resorption process.

CONCLUSION

This is the first study focussing on unexpected early resorption of primary molars and canines in 14 patients without agenesis. The study showed an abnormal resorption pattern of roots and crown of primary teeth before the permanent successor had barely begun root formation. This indicates that resorption of primary molars and canines may occur independently from eruptional processes in the succeeding permanent tooth.

Uprighting and distalisation of first permanent maxillary molars in patients with undermining resorption: a case report

This case report describes a treatment method for distalisation and uprighting of first permanent maxillary molars with the aim of preventing complications in the presence of undermining resorption of the second deciduous molar. We present a fixed appliance, which is a compliance-independent and effective alternative to the methods used thus far such as removable plates with distal screws or separating ligatures.

Pre-eruptive coronal resorption of a maxillary canine: a case report

This paper is the first to highlight a case of pre-eruptive coronal resorption of a maxillary canine in a patient undergoing extraction-based fixed appliance therapy. The etiology, clinical implications, and management of pre-eruptive coronal resorption are discussed.

Radiolucent lesion of an unerupted mandibular molar

A coronal radiolucent lesion of an unerupted and partially developed mandibular second molar was coincidentally found during a routine radiographic orthodontic examination of a generally healthy 9-year old girl. The size of the lesion increased continuously during a 2-year observation period. Histologic examination after extracting the tooth proved the lesion to be an idiopathic external coronal resorption. In a review of the literature, we found no original research on the subject. However, the number of case reports suggests that idiopathic external coronal resorptions are quite common in young patients. Their etiology, however, remains unclear. The case history, histologic findings, differential diagnoses, and possible treatment approaches suggested in the literature are described.

Treatment of severe pre-eruptive intracoronal resorption of a permanent second molar

Pre-eruptive intracoronal resorption is a lesion often located within the dentin, adjacent to the dentin-enamel junction, in the occlusal aspect of the crown. As the lesions resemble caries, they are often referred as "pre-eruptive caries." The purpose of this case report was to describe the diagnosis and treatment of a permanent molar with pre-eruptive intracoronal resorption and to elaborate on possible associated clinical problems. After surgical exposure of the unerupted tooth, the tooth structure in the resorbed area was removed and the tooth was restored with glass-ionomer material. Three months after the treatment, partial pulpotomy had been performed and the restoration was replaced by amalgam. Elaboration on possible associated clinical problems is provided.

A case of intracoronal resorption in a recently erupted mandibular canine in an 11-year-old girl is presented. Possible aetiology and approaches to treatment of such lesions are discussed.

Dental anomalies associated with amelogenesis imperfecta: a radiographic assessment

Amelogenesis imperfecta, a group of hereditary conditions primarily affecting the enamel, has been associated with dental anomalies, including taurodontism, congenitally missing teeth, delayed eruption, crown resorption, and abnormal enamel density. The purpose of this study was to assess the prevalence of these anomalies in an amelogenesis imperfecta population. The study group consisted of members of 9 unrelated families--22 family members with amelogenesis imperfecta and 13 unaffected family members. Panoramic radiographs were evaluated for taurodontism, congenitally missing teeth, delayed tooth eruption, pathologic dental resorption, pulp calcification, and radiographic enamel density. The prevalence of taurodontism was similar in people with amelogenesis imperfecta and normal people; all of the remaining parameters were more commonly observed in people with amelogenesis imperfecta. The radiographic enamel density was quantitatively reduced in teeth affected by amelogenesis imperfecta in comparison with teeth with normal enamel. These findings suggest that some of the features associated with amelogenesis imperfecta result from abnormal enamel formation (eg, decreased enamel density, crown resorption) whereas others may occur as a result of expression of the genetic mutation in cells other than ameloblasts (eg, abnormal eruption, pulp calcification).

Endodontic diagnosis in dogs

Complete endodontic evaluation should diagnose endodontic involvement, provide a treatment plan, and evaluate the true success or failure probabilities. Evaluation of the age, physical and oral health of the patient, the endodontic anatomy, clinical and radiographic findings can provide a treatment plan and a predictable prognosis.

Resorption in impacted teeth. A case report

External resorption of the crown in embedded teeth is uncommon. The authors present a case of an impacted third molar affected by this pathology and review its etiology, pathogenesis, radiological appearance, differential diagnosis and therapy.

Aneurysmal bone cyst of the maxilla--an association with tooth resorption

The aneurysmal bone cyst is an uncommon lesion of the jaws. Cases involving the maxilla have been reported infrequently. Despite uncertainty as to the aetiology of the aneurysmal bone cyst, it is regarded as a benign lesion. Conservative surgical treatment with regular postoperative follow-up is recommended. The case described here presented with tooth mobility resulting from extensive root resorption. A review of the literature reveals that significant root resorption is not a commonly reported feature of aneurysmal bone cysts. For the present case we interpret the evidence as supporting a diagnosis of idiopathic root resorption complicated by the formation of a aneurysmal bone cyst.

Experimental tooth ankylosis in the monkey

In this small study, radiographs and study casts were made of three Cynamoglus monkeys with deciduous dentitions. Roots were traumatized with a chrome-steel crown in hyperocclusion, and by exposing root surfaces surgically and traumatizing with a rotating bur or chemical irritants. Histologic studies revealed scalloping resorption of cementum but no evidence of ankylosis. However, when a maxillary deciduous incisor was luxated by forceps, block sections taken four weeks after the injury revealed areas of bone in close apposition to cementum. This last type of injury would seem to be one mechanism for producing dental ankylosis in the monkey.
