Evaluation of a new radiographic technique: outcome following removal of mandibular third molars.

OBJECTIVE: To compare the effect on outcome of third molar removal of pre-operative radiographic assessment by two different techniques. METHODS: Two hundred and sixty three patients were allocated prior to surgery to one of two diagnostic groups. One hundred and thirty-seven were examined by the Scanora and 126 by a panoramic plus three intra-oral radiographs. Ten oral surgeons recorded their operating time in minutes. Postoperative pain was recorded 4 h after the operation by the patients on a Visual Analog Scale (VAS). The following clinical parameters were recorded at the 1-week postoperative examination: alveolitis, bleeding, and swelling related to the operation area, and any other complications such as paresthesia, nausea and trismus. RESULTS: There was no significant difference in operation time between the two groups of patients (t-test; P > 0.82) nor in the frequency of immediate postoperative pain (chi 2-test; P > 0.5). There were no statistically significant differences in pain score between patients who experienced pain in the two groups (P = 0.10). Sixty-four patients experienced one or more postoperative complications, but the differences between the two groups were not statistically significant (chi 2-test; P > 0.05). There were no significant differences between the surgeons in the number of patients they operated on who experienced pain (chi 2-test; P = 0.18) or who developed complications (chi 2-test; P = 0.27). CONCLUSION: There are no adverse effects on the rate of postoperative complications when surgeons with little experience with it base their diagnosis and treatment plan on Scanora compared with conventional radiography.

Case report BC: extraction decisions based on treatment responses.

We have all been into treatment and lost sight of the "plan" we were so familiar with at the treatment planning stage. Eighteen to 21 months into treatment, we are faced with extraction decisions or surgical planning that should have been addressed at 9 or 12 months. This case report illustrates a treatment plan with several variables that were dependent upon treatment responses. It also illustrates planning a gingival graft to increase the crown length of a first premolar after the canine was substituted as the lateral incisor.

Familial occurrence of nonsyndromal multiple supernumerary teeth. A rare condition.

The occurrence of multiple supernumerary teeth is a rare phenomenon and is often found in association with syndromes such as cleidocranial dysplasia, Gardners syndrome, or cleft lip and palate. Only a few examples of nonsyndromal multiple supernumerary teeth have been reported in the literature. There is a predilection for the mandible and in the premolar area followed by the molar and anterior regions. This article reports the presence of nonsyndromal multiple supernumerary teeth involving both jaws in children and in their mothers. The clinical and radiographic appearance of the anomalies and treatment modalities are discussed.

Late forming supernumerary tooth in the premaxilla: a case report.

A case of late forming supernumerary tooth in the premaxilla is presented in this report. The patient has been followed-up radiographically from the age of 9 years but the supernumerary tooth could only be detected radiographically when the patient was 11 years old. This emphasises the importance of thorough clinical and radiographic examination of the developing dentition in children.

Spontaneous improvement in position of canines from apparently hopeless positions.

Two cases are presented, each with both unerupted maxillary canines so badly positioned that eruption seemed unlikely. However, over a period of approximately three years, three out of the four initially displaced canines did erupt; the improvements in position being unrelated to whether or not the associated primary canine was extracted. Three out of four primary canines were removed. These cases highlight the difficulties in predicting canine eruption for individual patients.

The role of magnets in the management of unerupted teeth in children and adolescents.

This case report describes the use of magnets in the management of teeth that fail to erupt. Eight children aged between 10 and 15 years were treated. Magnetic traction was applied to two premolars and six molars. Seven teeth (one premolar and six molars) erupted successfully (mean treatment time with magnetic traction: 7.5 months). One premolar failed to erupt; serial radiographic assessment over a 9-month period revealed no evidence of movement and so the magnetic fixture was removed. Histological evaluation of tissue samples taken from around the fixture revealed no evidence of abnormal pathology.

Compound odontoma associated with an unerupted and dilacerated maxillary primary central incisor in a young patient.

The occurrence of odontoma in the primary dentition is uncommon. There are very few reports of non-eruption of a dilacerated primary tooth in the literature. A rare case of compound odontoma in association with an unerupted dilacerated maxillary primary incisor in a young patient is reported. There was also a developing supernumerary tooth in the vicinity of the odontoma. The clinical features and management of these conditions are discussed. The relevant literature is reviewed. A possible causal relationship between odontoma and dilaceration is highlighted.

Age as a factor in the complication rate after removal of unerupted/impacted third molars at the time of mandibular sagittal split osteotomy.

PURPOSE: This study was designed to investigate the effect that the presence of an unerupted third molar has on the mandibular sagittal split osteotomy (SSO). PATIENTS AND METHODS: One operator performed 139 SSOs (70 right side and 69 left side) in 70 patients during a period of 6 months. Data related to gender, age, presence or absence of unerupted third molar teeth, split difficulty during SSO, fracture complications of the segment, neurovascular bundle involvement at surgery, removal of unerupted third molar teeth, and the postoperative recovery of nerve function were recorded. RESULTS: The SSOs evaluated as technically difficult were significantly more prevalent in mandibles with unerupted third molar teeth. All fractures (4) occurred in the younger age group (<20 years) with unerupted third molars present at the time of surgery. Although inferior alveolar nerve recovery was slower in the patients in whom the unerupted third molar teeth were present at the time of surgery due to increased frequency of neurovascular bundle manipulation, the recovery rates at 1 year were equal. CONCLUSIONS: The presence of unerupted third molar teeth increases the degree of difficulty of the SSO. Fracture of proximal and/or distal segments during SSO tend to occur more frequently in the younger age group (<20 years) with an unerupted third molar present.

[Damage to the remaining teeth from displaced upper canines].

25 patients with 35 retained upper canines were examined by high resolution CT; only 5 patients did not show evidence of damage to the remaining teeth. 8 patients showed resorption related to medial and lateral incisors. 19 teeth were in contact with the crowns of the displaced canines and were therefore liable to damage. The average extent of the resorption was 4.5 mm. Contact between teeth was demonstrable by means of two consecutive CT cuts.

Radiographic localization of unerupted teeth: further findings about the vertical tube shift method and other localization techniques.

The parallax method (image/tube shift method, Clark's rule, Richards' buccal object rule) is recommended to localize unerupted teeth. Richards' contribution to the development of the parallax method is discussed. The favored method for localization uses a rotational panoramic radiograph in combination with an occlusal radiograph involving a vertical shift of the x-ray tube. The use of this combination when localizing teeth and supernumeraries in the premolar region is illustrated. When taking an occlusal radiograph to localize an unerupted maxillary canine, clinical situations are presented where modification of the vertical angulation of the tube of 70 degrees to 75 degrees or of the horizontal position of the tube is warranted. The limitations of axial (true, cross-sectional, vertex) occlusal radiographs are also explored.

Use of an onplant as orthodontic anchorage.

Considerable limitations in the clinical application of orthodontic treatment can result from the lack of teeth suitable for anchorage. If prosthetic rehabilitation is necessary, endosseous implants can be first used as orthodontic anchorage and then loaded by a prosthetic superstructure. However, in a plan of exclusive orthodontic treatment, alveolar bone is not always available, and an orthodontic osseointegrated anchorage system might be necessary. We report the use of an onplant for palatal anchorage to extrude the unerupted horizontal maxillary first molars in a 12-year-old white girl with tooth aplasia and secondary cleft palate. After a healing period of 5 months, the onplant remained stable under indirect elastic tension of approximately 160 g applied for 17 weeks, and the maxillary first molars were successfully extruded.

Arrested eruption of the permanent lower second molar.

The incidence of retention/impaction of the permanent lower second molar (M2inf) lies between 0.6/1000 and 3/1000. Therefore, the purpose of the present study was to investigate the craniofacial morphology, the frequency of dental anomalies and the inclination of the affected M2inf and the adjacent first molar in patients with arrested eruption of M2inf. The overall goal was to elucidate the aetiology of arrested tooth eruption and to present the characteristics of these patients in order to improve diagnosis and treatment planning. Radiographic material (profile radiographs and orthopantomograms) from 19 patients (nine females and 10 males; 13-19 years of age at the time of referral) were analysed. The ages of the patients when profile radiographs were taken for cephalometric analysis varied from 8 to 16 years. The study shows that this group of patients, compared with a reference group, had an increased sagittal jaw relationship (Class II). Specifically, the mandibular prognathism was less, the mandibular gonial angle smaller, the mandibular alveolar prognathism enlarged and the maxillary incisor inclination less than in the reference group. Furthermore, this group of patients had a more frequent occurrence of morphological tooth anomalies, such as root deflections, invaginations, and taurodontism. However, none of the patients with arrested eruption of M2inf had agenesis of the lower third molar. The study did not reveal an association between the degree of inclination of the M2inf and that of the first molar in the same region. The results of this investigation show that conditions such as the craniofacial morphology and deviations in the dentition are associated with arrested eruption of M2inf. Therefore, it is important to evaluate these conditions in future diagnosis and treatment planning of patients with arrested eruption of M2inf.
