Periodontal status following surgical-orthodontic alignment of impacted central incisors with an open-eruption technique.
Several factors may affect the outcome of the orthodontic/surgical modality for the resolution of impacted central incisors, but particularly the manner in which the impacted tooth is exposed. The present study aimed to evaluate the post-retention clinical appearance and periodontal status of impacted maxillary central incisors which were exposed and aligned with an open-eruption surgical-orthodontic technique. Twelve subjects (four males, eight females), aged 22 years (range 15-38 years), previously treated for a unilateral impacted central incisor (ICI), were examined 10 years (range 3-25 years) post-retention. A split-mouth method was used for the comparison with the unaffected side. One treated central incisor exfoliated 10 years post-retention, thus the results were based on the remaining 11 patients. Statistically significant differences were found between the affected and control incisors in most of the periodontal parameters measured, although some were small and of minimal clinical importance. The increase in the mesio-labial pocket depth was associated with a highly significant 10 per cent reduction in bone level at this site (P = 0.007). A highly statistically significant increase in crown length (P < 0.001) and a reduction in the width of the attached gingiva (P = 0.005) were seen in these previously impacted teeth. An abnormal gingival contour was present in eight treated incisors and positional relapse in five cases. It is concluded that the convenience of the open-eruption technique must be weighed against the long-term negative aesthetic and periodontal effects on the treated tooth, although the findings of this study should be viewed with caution due to the limited sample size.

Factors influencing the non-surgical eruption of palatally impacted canines.
BACKGROUND: Many palatally impacted canines in children do not require surgical exposure prior to the start of orthodontic treatment. They erupt in mid-alveolar positions providing excess space is made for them in the arch. The time required for an impacted tooth to emerge under these conditions is highly variable. AIM: To determine the factors influencing the time required for a palatally impacted canine to spontaneously disimpact following orthodontic treatment to create excess space in the arch. METHOD: Thirty palatally impacted canines, which emerged following orthodontic treatment to open excess space in the arch, were used. The impacted teeth were present in 28 children. No canines were surgically exposed. The positions of the impacted canines before treatment, the mesiodistal widths and rotations of the adjacent and contralateral lateral incisors, age and gender of the subjects, subjects' dental ages, presence of either incisor or premolar hypodontia, number of subjects with bilaterally impacted canines, and number of siblings with impacted canines were recorded. Canines that erupted in less than nine months of treatment were compared with canines that required more than nine months of treatment. The canines were grouped by severity of impaction (sectors II - IV) and compared. RESULTS: There were significantly more severe (sector IV) impactions in the long duration group compared with the short duration group. Significantly more cases of incisor-premolar hypodontia were found in the short duration group. Canines impacted in sector IV emerged after 21 months of treatment and canines in sectors II and III emerged after eight months of treatment. Lateral incisors adjacent to the impacted teeth were rotated mesiolabially to a greater extent in the sector IV group compared with lateral incisors in the sector II group. Differences in rotation of the adjacent and contralateral lateral incisors were significantly less in the sector II group compared with the lateral incisors in the sector III and IV groups. CONCLUSIONS: The sector of impaction was the best guide to the duration of treatment prior to emergence.

Factor VII deficiency first observed at preoperative routine clotting test.
Factor VII deficiency was first observed in a 24-year-old female in the routine clotting test for tooth extraction. Her factor VII was 22%, mildly below normal limits. Factor IX complex was not administered as replacement therapy when her impacted tooth was extracted. There was no sign of abnormal postoperative bleeding. As this disease was a rare disorder, the minimum safe level of factor VII for tooth extraction was unknown. We had a opportunity to study a patient with this disorder observed in the preoperative routine clotting test for tooth extractions.

Immediate placement of implants in extraction sites of maxillary impacted canines.
BACKGROUND: Treatment of asymptomatic impacted maxillary canines in adults is inevitable when primary canine becomes lost through extraction or exfoliation or when the impacted tooth becomes symptomatic. Treatment alternatives include an orthodontic procedure to bring the unerupted tooth to the dental arch or prosthetic replacement of the missing tooth. The authors describe an alternative treatment that involves immediate placement of implants into extraction sockets of the teeth. CASE DESCRIPTION: A patient with bilateral palatally impacted upper canines chose to have the unerupted teeth removed and replaced with implants and crowns. Two hydroxyapatite cylindrical implants were inserted through the alveolar ridge into the extraction sites. The unfilled areas in the extraction sites, around the dental implants, were packed and covered with demineralized freeze-dried bone allograft in conjunction with a collagen membrane barrier. Six months after implantation, computed tomography revealed complete osseous fill of the extraction defects and no bone loss around the implants. The implants were uncovered, and porcelain-fused-to-metal restorations were fabricated and placed. CLINICAL IMPLICATIONS: This treatment modality avoids the need for conventional preparation of teeth as part of prosthetic reconstruction or prolonged orthodontic treatment aimed at bringing the impacted canine to the dental arch. Combining the implantation with bone augmentation preserved the alveolar bone and shortened the treatment period.

Calcifying odontogenic cyst: radiologic findings in 11 cases.
OBJECTIVE: This retrospective study examines the relationship between histopathologically diagnosed cases of in calcifying odontogenic cysts (COCs) on the adjacent dentition. STUDY DESIGN: The records including diagnostic radiograph images of 11 patients treated for COCs from 1991 to 2004 were analyzed and correlations made between radiologic and histopathologic features. Special attention was applied to the associations between COCs and adjacent teeth. RESULTS: Radiologic and histopathologic features of the 11 lesions were variable, with some lesions being more solid and others more cystic. Calcifications varied from small flecks to solid calcified areas of frank odontoma. In 7 cases, the COC was associated with an impacted tooth and 5 of these cases involved COC-enveloping teeth. All cases excepting one in an edentulous jaw segment showed positional changes of adjacent teeth, including impaction. CONCLUSIONS: The radiographical features of COCs are varied but there is a high frequency of changes in adjacent teeth, including dental impaction. The presence of impaction or displacement of teeth for COCs occurring in the posterior segments of the jaw, and absence of this finding for anteriorly placed lesions may be indicative of the timing of COC development.

[Evaluation of orthopantomographic X-ray technique in the diagnosis of impacted upper canine].
In this article advantages and disadvantages of orthopantomographic x-ray technique in the diagnosis of the impacted tooth are discussed. Twenty patients were examined by orthopantomographic technique as well as by standard retroalveolar radiographs. The investigation showed that the orthopantomographic technique was not a predominant method in the diagnosis of maxillar impacted canine and that the standard retroalveolar method was more reliable.

[The surgical-orthodontic classification of retained and dystopic teeth of the second dentition in dysostosis cleidocranialis].
Dysostosis cleidocranialis concerns both teeth and jaw and is characterized by supernumerary teeth, dentitio tarda, tooth impaction and eventually follicular cysts. The concept of treatment can be divided in two stages: 1. At the beginning of the delayed secondary dentition (dentitio tarda) the operative removal of the supernumerary tooth germs and 2. corresponding to the belated morphological development (dentitio tarda) the operative exposure of the impacted teeth of the secondary dentition. The first operation facilitates a morphological development and especially a vertical drift without any obstacles. The second becomes necessary when only the morphological development, but not the vertical drift of the teeth of the secondary dentition takes place. The operative exposure is done using a self-developed technique [13, 18]. At the same time as the exposed teeth undergo a spontaneous vertical drift, orthopedic treatment for anomaly is started.

The effect of tooth position on the image of unerupted canines on panoramic radiographs.
The purpose of this study was to evaluate whether panoramic tomograms, which are routinely used in orthodontic practice, can provide adequate information to localize an impacted canine. The effect of changes in position and inclination of an impacted canine on orthopantomograms was investigated in an experimental set-up. An upper canine was removed from a human skull and replaced in a positioning system, enabling simulated positional variations in impactions. In comparison with the image of a contralateral well-aligned canine, the length of the impacted tooth always decreased or remained unchanged, whereas the tooth width increased or remained unchanged. The angulation of the image was unaffected by varying the position of the impacted canine, but altered when the inclination of the tooth in a sagittal or frontal direction was changed. If there was any transversal shift of the impacted canine on the orthopantomogram, it was always towards the mid-sagittal plane. The curvature of the tooth increased after dorsal inclination and decreased after ventral inclination (in comparison with the contralateral well-aligned canine).

Periodontal concerns associated with the orthodontic treatment of impacted teeth.
Impacted teeth are common and are often treated with orthodontic eruption, but periodontal problems associated with the process can evade detection. Profound destruction of the periodontium of an impacted tooth or adjacent teeth can occur. This case report describes the orthodontic eruption of 4 impacted canines in a 19-year-old woman. An open surgical approach was used. Within 6 months of treatment, the maxillary right canine and the lateral incisor experienced severe periodontal destruction, resulting in questionable prognoses for the teeth. Plaque control, periodontal architecture, and subgingival microflora were examined as local etiologic factors of periodontal destruction associated with orthodontic eruption of impacted teeth. Plaque control measures were evaluated, and the consequences of orthodontic tooth movement in the presence of inadequate plaque control were considered. Areas of periodontal architecture made vulnerable by the surgical exposure of the impacted teeth were identified, and the effect of orthodontic force on the periodontium was explored. An increase in putative periopathogens in the subgingival microflora after orthodontic appliance placement was observed. Microbiologic monitoring for pathologic levels of periopathogens and antibiotic therapy were considered. Orthodontic treatment of impacted teeth might require additional professional and personal plaque control measures, 3-dimensional diagnostic imaging, and control of putative periopathogens to preserve the health of the periodontium.

Dietary intake and the extraction of third molars: a potential problem.
The most common form of oral surgery is extraction of impacted third molars. The patient may suffer a period of impaired food intake before extraction because of the discomfort caused by the impacted tooth. This may compound poor intake for other reasons, for example poverty. After surgery, the patient undergoes several days of pain and swelling, which delays a return to normal eating. The relationship between surgery for impacted third molars and diet has not been documented, nor is dietary advice routinely offered. The aim of this study was to describe the diet of patients before and after extraction of third molars. Patients recorded everything they ate for 7 days before and after surgery. These records were converted into estimates of nutrient intake. A substantial fall in energy intake occurred which had not been corrected even a week after surgery. The nutritional implications of this are not yet clear. Practitioners are strongly advised to warn patients of the likelihood of serious disturbance to their lifestyle and to offer them simple dietary advice.

[Should we or should we not extract impacted teeth?].
Do we have to remove the impacted teeth? The pathology of an impacted tooth is reviewed by the author as well as the possible complications of its removal and others treatment possibilities. Seeing the increase of pathology and operative complications owing to the age, the author propounds the management of immature impacted third molars when they are not in a propitious position or when the posterior eruption space is reduced. About the impacted teeth covered partially or completely by soft tissue, his advice consists too in removing them if they don't have the possibility to take up good position on the dental arch.

Maxillary impacted canine with congenitally absent premolars.
Multiple treatment options are available to patients who have impacted canines in addition to congenitally absent premolars. Management options for impacted maxillary canines can include (1) continued observation, (2) extraction of the primary canine to aid spontaneous eruption, (3) uncovering and bonding of the impacted tooth and its eruption using orthodontic traction, (4) autotransplantation, and (5) extraction followed by prosthetic replacement. The options for the treatment of missing premolars can include the following: (1) maintaining the primary molars, (2) spontaneous space closure after early extraction of the primary molar, (3) autotransplantation, (4) prosthetic replacement, and (5) orthodontic space closure. In this case report, treatment of a patient with an impacted maxillary canine and agenesis of three second premolars will be presented.
