Orthodontic treatment of a patient with multiple supernumerary teeth and mental retardation.

Supernumerary teeth may lead to impaction or ectopic eruption of maxillary incisors, crowding, oronasal fistula, follicular cyst, migration of adjacent teeth and root resorption. In this presentation, an 11-year-old male patient with 4 supernumerary teeth in the maxillary anterior region and a slight mental retardation problem will be presented. After extraction of the supernumerary teeth, the large space created by distal migration of central incisors was closed by orthodontic treatment. Although initial patient compliance was weak and caused difficulties in the course of treatment, orthodontic treatment was completed successfully.

A comparison of autotransplantation and orthodontics in a case exhibiting two ectopic upper cuspids.

Bilateral severely ectopic maxillary cuspids were treated differently on each side. On one side the ectopic cuspid was moved into position orthodontically, and on the other, the ectopic cuspid was positioned by autotransplantation. The orthodontic positioning took a long time and the tooth exhibited root resorption. Treatment time for the autotransplantation positioning was far quicker, and there was no resorption nor were there any other side effects.

A review of impacted permanent maxillary cuspids--diagnosis and prevention.

As impacted permanent maxillary cuspids occur in 1-2% of the population, the general dentist should know the signs and symptoms of this condition and the interceptive treatment. Features of buccal or palatal cuspid impaction include lack of canine bulges in the buccal sulcus indicating a lingual eruption path and possible impaction; lack of symmetry between the exfoliation and eruption of cuspids that may indicate palatal or lingual impaction; and abnormal mesiodistal location and angulation of the developing maxillary permanent cuspids on radiographs. Diagnosis of impacted cuspid teeth at age 8-10 years can significantly reduce serious ramifications, including surgical exposure and orthodontic alignment as well as root resorption of the lateral incisors. In specific cases, extraction of the primary maxillary cuspids can prevent impaction of the permanent maxillary cuspids and additional sequelae.

[Orthodontic treatment for adults].

The number of adults undergoing orthodontic treatment has increased strongly and the average age that adult patients undergo orthodontic treatment increased steadily although 3/4 is still younger than 27 years. In adults the facial skeletal pattern can only be changed in a very confined way, consequently in case of an abnormal skeletal pattern one has to choose between a combined orthodontic-surgical approach (which is the case in 18% of the patients) and a compromised orthodontic treatment, if necessary combined with other disciplines. It is still controversial whether tooth movement in adults is slower and more difficult than in adolescents. The same holds true for the risk for loss of periodontal support, for root resorption, for gnathologic problems and for relapse. As related to these variables there appears to be a large individual variation. Many adults show one or more problems in their dentition that may influence their orthodontic treatment. About 60% of the adult patients need a multidisciplinary approach. The development of implantology and of bone regeneration and bone grafting has lead to more combined treatments. The risks of such complex treatment plans are generally larger than those for more simple kinds of treatment. A very careful treatment planning and good communication between the different specialists is essential. Moreover the treatment plan with all its (dis)advantages has to be extensively discussed with the patient.

Rapid orthodontics with alveolar reshaping: two case reports of decrowding.

Two case reports demonstrate a new orthodontic method that offers short treatment times and the ability to simultaneously reshape and increase the buccolingual thickness of the supporting alveolar bone. A 24-year-old man with a Class I severely crowded malocclusion and an overly constricted maxilla with concomitant posterior crossbites and a 17-year-old female with a Class I moderately to severely crowded malocclusion requested shortened orthodontic treatment times. This new surgery technique included buccal and lingual full-thickness flaps, selective partial decortication of the cortical plates, concomitant bone grafting/augmentation, and primary flap closure. Following the surgery, orthodontic adjustments were made approximately every 2 weeks. From bracketing to debracketing, both cases were completed in approximately 6 months and 2 weeks. Posttreatment evaluation of both patients revealed good results. At approximately 15 months following surgery in one patient, a full-thickness flap was again reflected. Visual examination revealed good maintenance of the height of the alveolar crest and an increased thickness in the buccal bone. The canine and premolars in this area were expanded buccally by more than 3 mm, and yet there had actually been an increase in the buccolingual thickness of the overlying buccal bone. Additionally, a preexisting bony fenestration buccal of the root of the first premolar was covered. Both of these findings lend credence to the incorporation of the bone augmentation procedure into the corticotomy surgery because this made it possible to complete the orthodontic treatment with a more intact periodontium. The rapid expansive tooth movements with no significant apical root resorption may be attributed to the osteoclastic or catabolic phase of the regional acceleratory phenomenon. Instead of bony "block" movement or resorption/apposition, the degree of demineralization/remineralization might be a more accurate explanation of what occurs in the alveolar bone during physiologic tooth movement in these patients.

Indirect pulp treatment: in vivo outcomes of an adhesive resin system vs calcium hydroxide for protection of the dentin-pulp complex.

PURPOSE: The purpose of this prospective and randomized in vivo study was to compare the clinical and radiographic outcomes of an adhesive resin system vs a calcium hydroxide liner for protection of the dentin-pulp complex of primary molars treated with indirect pulp treatment. METHODS: Forty-eight primary molars with deep occlusal caries, but without preoperative signs and symptoms of irreversible pulpitis, received indirect pulp treatment and were restored with a composite resin (Z100). The teeth were randomly divided into 2 groups according to the material used for protection of the dentin-pulp complex: (1) adhesive resin system (Scotchbond MultiPurpose); and (2) calcium hydroxide liner (Dycal). These teeth were evaluated clinically and radiographicaly for 2 years. RESULTS: After 2 years, 83% (19/23) of the teeth treated with calcium hydroxide and 96% (24/25) of teeth treated with only the adhesive resin system presented a successful outcome, as determined by clinical and radiographic examination. Interradicular and/or periapical lesions were the most predominant signs of treatment failure, since 3 out of 23 teeth treated with calcium hydroxide and 1 out of 25 teeth treated with only adhesive resin presented this outcome. One tooth treated with the calcium hydroxide liner was diagnosed with internal root resorption at the 18-month examination. Of the 5 teeth diagnosed from radiographs as a failure of the indirect pulp treatment, none presented clinical signs/symptoms of pulpitis or necrosis such as the presence of fistula, enhanced tooth mobility, or pain. CONCLUSIONS: This study demonstrates that protection of the dentin-pulp complex of primary molars with an adhesive resin system results in similar clinical and radiographic 2-year outcomes as compared to calcium hydroxide when indirect pulp treatment is performed in Class I composite restorations.

The relationship of maxillary cheek tooth development to age in young Friesian cattle.

Radiographs were taken of both the right and left sets of maxillary teeth in 23 Friesian cattle of known age. The stage of development of each permanent tooth was ascertained and the degree of root resorption in the deciduous premolars was noted. All stages in individuals were later than for those of the mandibular cheek teeth except in the case of the first permanent premolar. As with mandibular cheek tooth development stages of formation occurred within certain age limits.

[A new splint technique in dental traumatology].

The treatment of displacement injuries and fractures of permanent teeth is an important emergency therapy in the dental office. Due to new sport trends and various outdoor activities, the frequency of dental trauma of children and adolescents alike is steadily rising. The standard treatment of displacement or avulsion injuires of permanent teeth is repositioning or replantation with subsequent splinting. The dental trauma splint must be flexible to allow for the physiologic movement of the repositioned or replanted teeth in order to reduce the risk for ankylosis or external root resorption. Stabilization of a repositioned tooth with a flexible splint over a short time period optimises the rehabilitation of the periodontal tissues. In the literature various splinting techniques have been described. This paper presents a new splinting technique; the Titanium Trauma Splint (TTS), which is made of pure titanium and was specifically developed for the treatment of traumatically displaced or avulsed permanent teeth. The TTS-splint has certain advantages when compared to traditional splinting techniques. These advantages are beneficial both for the dentist and patient alike.

Supernumerary teeth diagnosis and treatment approach. Six case reports.

Supernumerary teeth are relatively common in the general population, affecting the primary and the permanent dentition and have been reported in many genetic syndromes. They are classified according to form and shape. Seven different examples of hyperodontia are presented to highlight the numerical and morphological variation in dental abnormalities manifestations, empathising the importance of thorough clinical and radiological examination and of a correct therapeutic approach. The patients presented single or multiple hyperodontia, with particular interest for a 12 supernumerary teeth case. The clinical problems linked to supernumerary teeth were: impaction or ectopic eruption, crowding, possible root resorption of adjacent teeth. The therapeutical approach of supernumerary teeth varied on the position of the element in excess and on the complexity of the clinical case. In some cases the single extraction of the supernumerary tooth was indicated, while in other cases the extraction of the tooth was needed in addition to orthodontic treatment to gain sufficient space for the tooth with delayed eruption.

Prevalence of impacted teeth and associated pathologies--a radiographic study of the Hong Kong Chinese population.

OBJECTIVES: To investigate the prevalence and pattern of impacted teeth and associated pathologies in the Hong Kong Chinese population. SETTING: The Reception and Primary Care Clinic, Prince Philip Dental Hospital, Hong Kong. DESIGN: Retrospective study. SUBJECTS AND METHODS: The records of 7486 patients were examined to determine whether the chief complaints were related to impacted teeth and associated pathologies, which were investigated using panoramic radiographs. RESULTS: A total of 2115 (28.3%) patients presented with at least one impacted tooth. Among the 3853 impacted teeth, mandibular third molars were the most common (82.5%), followed by maxillary third molars (15.6%), and maxillary canines (0.8%). Approximately 8% of mandibular second molars associated with impacted third molars had periodontal bone loss of more than 5 mm on their distal surfaces. Caries were also found on the same surfaces in approximately 7% of the second molars. Approximately 30% of patients with dental impaction had symptoms, and 75% had complaints limited to one side of the mouth. CONCLUSIONS: The prevalence of impacted teeth was high, and there was a predilection for impacted third molars in the mandible. More than 50% of maxillary third molars had erupted, creating potential trauma of the pericoronal tissues of the partially erupted mandibular third molars. Caries and periodontal diseases were commonly seen in relation to the impacted third molars, whereas cystic pathology and root resorption were rarely observed.

Current concepts in vital primary pulp therapy.

REVIEW: Recent progress in understanding the molecular and cellular changes during tooth development and how they are mimicked during tissue repair, offers the opportunity to assess the biologic validity of the various vital pulp treatments. Under this light, indirect pulp treatment can be an acceptable procedure for primary teeth with reversible pulp inflammation, provided that this diagnosis is based on a good history, a proper clinical and radiographic examination, and the tooth had been sealed with a leakage-free restoration. Several articles report the success of this technique of direct pulp capping (DPC) and calcium hydroxide has been widely used with high success rates in young permanent teeth, but the results in primary teeth are less satisfactory. Recent studies have reported successful results with direct adhesive capping of exposed pulps, while others showed pulp inflammation and unacceptable results using this technique. Thus, the traditional rationale for the use of calcium hydroxide should be maintained, and this treatment modality reserved for iatrogenic exposures in asymptomatic teeth that are expected to exfoliate within a short period of time. In younger children, iatrogenic or carious exposures should be treated by pulpotomy. Formocresol has been the most popular pulp dressing material for pulpotomized primary molars for many years but, due to its deleterious effect, the use of formocresol is decreasing considerably worldwide. Ferric sulphate has been proposed as a substitute to formocresol, and the success rates were comparable to those of formocresol. More recently, considerably better results have been obtained with MTA (Mineral Trioxide Aggregate), and statistically significant differences were reported when compared with formocresol. Internal root resorption, a finding seen both in ferric sulphate and formocresol, was not observed in the MTA treated teeth. MTA is commercially available, but its cost is very high, and cannot be kept once opened. Thus, ferric sulphate can still be a valid and inexpensive solution for pulpotomies in primary teeth.

Ferric sulphate and formocresol pulpotomies in baboon primary molars: histological responses.

AIM: To compare pulpal reactions to ferric sulphate and formocresol pulpotomies in primary molar teeth with inflamed pulps. STUDY DESIGN: An experimental study in 15 juvenile baboons (Papio ursinus). MATERIALS AND METHODS: Pulpitis was induced with fresh human carious dentine or Streptococcus mutans placed into occlusal cavities in 57 primary molars; after 14 days a pulpotomy was performed on the same primary molars with the two pulp medicaments randomly allocated; the pulp was covered with IRM and the cavity filled with amalgam. After 90 days specimens were harvested and examined under the light microscope with the examiner blind to the treatment. RESULTS: Reaction frequencies in the ferric sulphate-treated and formocresol-treated teeth were: recognisable pulp 52% and 50%, dentine bridges 16% and 12%, internal root resorption 12% and 4%, external resorption 28% and 31%, bacteria 12% and 23%, peri-apical abscesses 32% and 38%. STATISTICS: Fisher's exact probability test showed no statistically significant differences between reaction frequencies in the two treatment groups. CONCLUSION: A pulpotomy in a primary tooth may be clinically successful in the presence of adverse histological reactions.

Central giant cell granuloma of the jaws: a clinical and radiologic study.

PURPOSE: The purpose of this study is to present the clinical and radiological features of 27 cases of central giant cell granuloma (CGCG) of the jaws. MATERIALS AND METHODS: This study was carried out on 27 cases diagnosed as CGCG, ranging in age from 8 to 70 years. The patient's age, sex, location of the lesion, expansion caused by the lesion, and greatest diameter were evaluated. Radiographs and radiological descriptions were studied for the features of border definition, radiopacity, locularity, root resorption, tooth displacement, and tooth association. Data were analyzed with Chi square test, Fisher's exact test, Mann Whitney U-test, and the Student t-test. RESULTS: It was determined 89% of CGCG occurred prior to the age of 40. Seventy-eight percent of the cases were females. In addition, it was observed that these lesions occurred primarily in the mandible mostly anterior to the molar region. It was determined most of the lesions were multilocular. Unilocular lesions averaged 23.75 mm and multilocular lesions were 53.00 mm. In 24 (89%) cases regular borders were seen, and in three cases diffuse borders were observed. There was bone expansion in 44% of the cases. The cases with bone expansion were 60.00 mm in average size, and the cases without bone expansion were 24.00 mm in average size. Seventy-eight percent of lesions were associated with teeth, and there was tooth displacement in 43% of these lesions. The lesions with tooth displacement were 18.33 mm in average size, and the lesions without tooth displacement were 44.00 mm in average size. CONCLUSIONS: It was determined there is a significant correlation between the locularity, tooth displacement, and bone expansion with the size of the CGCG.

[Results after short- and long-term observations of bone transplantation to vertical, marginal bone defects].

The effect of autologue bone transplantation to 26 vertical, marginal bone defects has been investigated on a long-term scale ranging from 2 to 26 years. The operation technique included excision of gingival pocket epithelium, removal of granulation tissue, and cleansing of the root surface with scalers. The bone cavities were filled preferably with cancellous bone chips, usually from the patients' upper third molar region. After suturing, the area was covered with a wound paste for 12-14 days. Loosened teeth were splinted for at least 2 months. In 25 of 26 teeth (96%) a bone regeneration was observed radiographically. The maximum healing of 22 cases occurred 2-12 months (median 6 months) postoperatively (Table 1). The maximum healing was maintained for more than half of the teeth (56%) at the last control, median 16 years (range 2-26 years), and none of these teeth were extracted of periodontal causes. They might therefore be expected to function for still a long time. Eight teeth (32%) showed more or less recurrence when controlled 5 to 15 years (median 10 years) after operation and 6 of the 8 teeth with recurrence were extracted. Three teeth (12%) developed root resorption and were extracted 6, 10 and 14 years postoperatively. As most of the complications occurred after extended observation periods, this factor has to be taken into account when prognosis of periodontal treatment procedure is considered.

Update on materials used in intracoronal bleaching.

Intracoronal bleaching has emerged as a popular technique to bleach discoloured, endodontically treated anterior teeth. Although hydrogen peroxide and sodium perborate have traditionally been used in intracoronal bleaching, some concern has been expressed regarding the use of hydrogen peroxide, mainly because of the suspected "cause and effect" relationship between hydrogen peroxide and invasive cervical root resorption. Other complications associated with use of hydrogen peroxide alone or in combination with sodium perborate include increased dentine permeability, alteration in the chemical structure of dentine, and general weakening of physical properties of dental hard tissues. This has prompted researchers to look for alternative bleaching agents as effective as the traditional bleaching agents but unassociated with such complications. Some of these alternatives have been shown to be as effective as sodium perborate in lightening tooth colour under in vitro conditions and may represent a useful alternative to the traditional materials that are currently in use.

Therapeutic protocols for avulsed permanent teeth: review and clinical update.

Traumatic injuries to permanent teeth include coronal and root fractures, subluxations, luxations, and avulsions. The most common complications after avulsions are necrosis of the pulp and root resorption. Treatment is often complex, time consuming, and expensive and requires multidisciplinary approaches such as endodontic and periodontal treatments, surgery, orthodontic movements, as well as esthetic coronal restoration. This review describes new clinical modalities for the treatment of avulsed teeth and discusses the rationale for their use.

Impacted mandibular second molar with extruded maxillary second molar: a case report.

AIM: To present a method for correction of an extruded maxillary second molar. METHODS: A female patient, 16 years of age, presented with an impacted mandibular second molar and an extruded opposing maxillary second molar. After placement of appliances in the maxilla, an elastic was hooked between the distal end of the extended lingual arch and the lingual button of the maxillary second molar. RESULTS: After sufficient intrusion of the maxillary second molar was achieved, the conventional method for traction of an impacted mandibular second molar was used. Neither root resorption nor undesirable periodontal problems were observed. CONCLUSION: The approach used in the present case is simple and efficient for both traction and retention of a maxillary molar.
