Microscopic and histochemical evaluation of demineralized freeze-dried bone allograft in association with implant placement: a case report.

A case report is presented in which a titanium implant was placed into a defect resulting from the extraction of an impacted tooth; the defect was filled with demineralized freeze-dried bone allograft particles without a membrane barrier. After a 6-month healing period the bone defect had completely healed and the tissue present had macroscopic features similar to mature bone. Histologic examination of this tissue showed that, in all demineralized freeze-dried bone allograft particles, mineralization nodules were scattered inside the demineralized bone; in the areas where the mineralization nodules were present, osteocyte lacunae could be observed. In the case presented, significant new vital bone formation was observed 6 months after placement of a demineralized freeze-dried bone allograft.

[A supernumerary primary tooth inducing impaction of primary incisor: a case report].

A case of a primary supernumerary tooth in a 18 month old girl was reported. 1. The supernumerary tooth was located in the maxillary incisor area. 2. The maxillary left primary central incisor and the primary supernumerary tooth were impacted. 3. The clinical and radiographic findings indicated that the primary tooth in the mesial position was the supernumerary tooth, and therefore it was removed. 4. Three days after extraction of the mesiodens, the left primary central incisor erupted. The tooth completely erupted in two months. 5. The radiographic examination showed no supernumerary succedenous teeth.

The impact of tooth loss in a denture wearing population: an assessment using the Oral Health Impact Profile.

OBJECTIVES: To assess the impact of tooth loss in complete denture wearers using the Oral Health Impact Profile (OHIP), and to compare the validity of 49 and 14 item versions of OHIP in a denture wearing population. DESIGN: In this cross sectional study, data were collected at Newcastle Dental Hospital, UK. Two groups were involved: (1) subjects edentulous in one or both jaws seeking dental implants to retain their intra-oral prostheses (n = 48); (2) an edentulous control group of the same age and gender distribution requesting conventional, complete dentures (n = 35). All participants in the study completed a 49 item OHIP (OHIP-49) and a validated denture satisfaction questionnaire prior to active treatment. OHIP data were computed using the weighted standardised and simple count methods. Non-parametric statistical tests were used to compare the responses of implant and control subjects. RESULTS: Both groups were dissatisfied with their conventional dentures and had relatively similar levels of dissatisfaction. There were statistically significant differences between the groups for all seven OHIP-49 sub-scale scores. Differences between OHIP-14 sub-scale scores were also significant, with presence of teeth influencing the impact on psychological discomfort. CONCLUSION: Subjects in the implant group were significantly more impaired, disabled and handicapped by tooth loss than subjects seeking conventional dentures. The results suggested that OHIP-49 and OHIP-14 had a similar ability to discriminate between the groups. This indicates that OHIP-14 may be a useful aid in a clinical setting.

Impacted supernumerary tooth developed under palatal polyp.

We present a rare case of an infant's palatal polyp associated with an impacted supernumerary tooth. We have previously reported three cases of palatal polyps in infants [1]. In one case, after surgical removal of the palatal polyp at the age of 1 year and 8 months, the lesion subsequently began swelling. A periapical radiograph at the age of 2 years and 9 months revealed a small calcified mass in the maxillary left incisor region. The swelling was kept under observation, the calcified mass developed gradually and was removed surgically at the age of 5 years and 5 months. The removed calcified mass was clinically diagnosed as an impacted supernumerary tooth and this was confirmed histologically. Histological findings did not indicate any relationship between the palatal polyp and the impacted supernumerary tooth.

[The submasseteric abscess as a complication of the semi-impacted wisdom tooth infection].

The submasseteric abscess is a serious problem related with the semi-impacted mandibular wisdom-tooth infection. Especially severe complications are long-term trismus and osteomyelitis of the mandibular ramus. Treatment must be radical and depends on the stage of the infection (acute or chronic, early or mature). Important remains the preventive extraction of the responsible third molar.

Impacted teeth in the maxilla: usefulness of 3D Dental-CT for preoperative evaluation.

OBJECTIVE: To compare the shapes of roots of impacted teeth shown in three-dimensional computed tomographic images (3D Dental-computed tomography (CT) images) and plain radiographs and to determine whether 3D Dental-CT images are useful for examination before performing an operation for extraction of a maxillary impacted tooth. METHODS AND PATIENTS: Images obtained from patients who had impacted teeth in the maxilla, including impacted mesial supernumerary teeth in 13 patients, impacted incisors in two patients, impacted canines in 11 patients, impacted premolars in four patients and impacted molars in three patients, were used in this study. In all patients, plain radiographs and 3D Dental-CT images were retrospectively reviewed by an oral radiologist for evidence of root dilaceration before operations to extract the impacted teeth were performed. The findings in the images were compared with intraoperative findings in all cases. RESULTS: The mean specificity and sensitivity of plain radiographs were 95 and 8%, respectively, while those of 3D Dental-CT images were 100 and 77%, respectively. There was a statistically significant (P<0.01) difference between the depiction capabilities of plain radiographs and 3D Dental-CT images with regard to dilacerations of roots of impacted teeth. DISCUSSION AND CONCLUSION: CT may enable radiologists to make a quick and accurate diagnosis of tooth impaction. 3D Dental-CT images are useful for determining the root shape of an impacted tooth in the maxilla.

The impact of tooth loss on general health related to quality of life among elderly Pomeranians: results from the study of health in Pomerania (SHIP-O).

PURPOSE: It is important to know whether tooth loss has an impact on an individual's quality of life, since tooth loss is common. The aim of this study was to determine whether oral status is associated with general health and related to quality of life. MATERIALS AND METHODS: Data of 1,406 subjects aged 60 to 79 years were taken from the Study of Health in Pomerania (SHIP). Sociodemographic (age, sex, and education level) and medical information (including the most common diseases in Germany) were gathered through an interview, and income data were obtained from a self-administered questionnaire. The prosthetic status in the maxilla and mandible was classified into complete denture or removable partial denture or with > or = 10 natural teeth including teeth replaced with fixed prosthodontics (> or = 10T) or with < or = 9 natural teeth including fixed prosthodontics (< or = 9T). The health-related quality of life was measured using the Short Form (SF-12) questionnaire. Multiple linear logistic regression analyses were used to identify the nonstandardized beta coefficient using physical and psychologic indices from the SF-12 as dependent variables and sociodemographic information, prosthetic status, and disease state as independent variables. RESULTS: Prosthetic status is related to the physical scale of the SF-12. Additionally, we found that < or = 9T had a significant effect on the physical index of general health-related quality of life. CONCLUSION: Reduced dentition without replacement of missing teeth by removable or fixed prosthodontics reduces the physical index of quality of life to the same extent as cancer or renal diseases.

Treatment options for impacted teeth.

BACKGROUND: A compilation of treatment options for impacted teeth is presented to assist dentists in discussing the sequelae of impacted teeth as well as the complications of treatment with their patients. OVERVIEW: A differential diagnosis for an impacted tooth is not possible without clinical assessment. However, an ankylosed tooth or a tooth with failure of its eruption mechanism may be mistaken for an impacted tooth. This review of national and international dental texts, journals and publications concerning impacted teeth spans more than 50 years. PRACTICE IMPLICATIONS: Treatment options for the management of impacted teeth are separated into four categories: observation, intervention, relocation and extraction. The indications, contraindications and complications of each option are presented. This information will help the clinician identify developmental conditions associated with an increased probability of tooth impaction and assess available treatment options.

Misdiagnosis of an impacted supernumerary tooth from a panographic radiograph.

A panographic radiograph of a 31-year-old man revealed the presence of an impacted supernumerary paramolar. Periapical radiographs of the same area failed to confirm the existence of this supernumerary tooth. A review of the inherent distortion factors present in panographic radiography leading to the misdiagnosis is discussed.

Aggressive growth and neoplastic potential of odontogenic cysts: with special reference to central epidermoid and mucoepidermoid carcinomas.

An aggressive form of odontogenic cyst known as the keratocyst has been reviewed with a report on the findings of 70 new instances. Recurrence after 2 years of followup was found to be 20%. From both a review of the literature and original cases, carcinomatous and ameloblastomatous transformation in odontogenic keratocysts seems to be an extremely rare phenomenon. Alternatively, epidermoid carcinoma and mucoepidermoid carcinoma arising centrally within the jaws are often associated with other types of dental cycts. Review of 36 instances of central epidermoid carcinoma has disclosed that 75% were associated with a cyst lining; the 2-year survival rate was found to be 53%. Central mucoepidermoid carcinoma was associated with a dental cyst or impacted tooth in 48% of the cases, and enjoyed a 100% 2-year and 5-year survival; however, 2 patients were recorded alive with disease at 4 months and 10 years, whereas another patient succumbed to disease 14 years postoperatively.

Benign cementoblastoma.

An unusual case of cementoblastoma is presented. It is the second case to be published demonstrating involvement of the pulp, and it is the first instance of a cementoblastoma that appears to have evolved from an impacted tooth. A review of the literature substantiates the fact that this lesion may not be so uncommon as was previously thought, and that pain and facial asymmetry may be significant clinical features.

Long-term follow-up of severely resorbed maxillary incisors after resolution of an etiologically associated impacted canine.

BACKGROUND: Resorption of maxillary incisor roots because of an impacted canine is a well-recognized phenomenon that occurs in a surprisingly high proportion of patients with impacted canines. In this retrospective study, we studied a sample of patients in whom the resorption was particularly severe. METHODS: The sample consisted of 11 patients (age, 11.8 +/- 1.2 years) with 20 severely resorbed maxillary incisors. The amount of resorption was measured at the outset (T1), when the impacted canine was distanced from the incisor root area (T2), at the completion of the orthodontic treatment (T3), and at a follow-up appointment at least 1 year posttreatment (T4). RESULTS: A 17.2% increase in the crown/root ratio occurred due to aggressive continued resorption between T1 and T2. The resorption rate reduced to an almost insignificant level, despite continued and often appreciable orthodontic movement of the resorbed teeth from T2 to T3. CONCLUSIONS: Patients with impacted canines should be screened for resorption and the impacted tooth treated as soon as possible. The resorption process can be halted and the affected tooth moved orthodontically without further risk of resorption. In the long term, with early treatment, even severely resorbed teeth do not suffer from increased mobility or discoloration and might not require splinting.

The resolution of palatally impacted canines using palatal-occlusal force from a buccal auxiliary.

Palatally impacted canines can usually be mechanically drawn directly to the labial arch wire after they have been surgically exposed. Occasionally, the direct line between the impacted tooth and the arch wire is obstructed by the presence of the root of the lateral incisor, or the tooth is very superiorly displaced, which makes direct traction ill-advised and impractical. In this situation, it is recommended that the tooth be erupted vertically downward, through the palatal tissue on the palatal side of the dental arch, as a first stage and, only then moved buccally into its place in the arch. This article describes a method whereby an auxiliary spring is placed on the buccal side of the arch to produce the vertical and palatal traction needed. There are no palatal accessories, and the auxiliary is tied in, "piggy-back" fashion, over the main base arch, by using the multibracketed appliance already present.

Surgical and orthodontic treatment of an impacted permanent incisor: case report.

This case report presented a combined surgical/orthodontic treatment of an impacted permanent incisor of a 10-year-old boy. Trauma to the primary dentition caused the impaction of the maxillary left permanent central incisor. Application of push coil spring between the adjacent teeth created space for the impacted tooth. A button with an extension of ligature wire was bonded to the maxillary left permanent central incisor to bring it into the arch. The maxillary left permanent central incisor was brought to its proper position after 16 months of active orthodontic treatment.
