This study examines the treatment of non-vital immature permanent incisors using the calcium hydroxide apexification technique. The objectives of the present study were to determine the speed and location of barrier formation and those factors discernible at presentation and during treatment which may be related to it. Forty-four non-vital immature ...

Surgical management of unerupted teeth depends upon a thorough understanding of anatomic, physiologic and pathologic factors. Attention has been given to problems of eruption in the maxillary anterior region. It is a region where a variety of anomalies occur. Since the maxillary anterior region influences appearance so greatly, early detection ...

Intentional replantation has been practised for many years as a treatment modality for pulpless teeth. Although the success ratio for intentional replantation is far below that for routine or surgical endodontics, one should consider this procedure as an alternative to tooth extraction. Two cases of mandibular second molars which were ...

The case of a 61-year-old woman with a primary diagnosis of spondyloepiphyseal dysplasia and severe maxillary and mandibular spacing as well as anterior and posterior crossbites is presented. Clinical findings led to a diagnosis of macroglossia which required partial glossectomy in addition to comprehensive orthodontic treatment to correct malocclusion.

The case of GAPO syndrome reported here is the 24th recorded case, 23 cases having been published previously. The 29-year-old male under discussion presents all the typical features of the syndrome, having short stature, dysmorphic craniofacial features, total alopecia and pseudoanodontia. Orally, the erupted primary dentition was extremely worn and ...

METHOD: Records were obtained for 1527 cases, representing a systematic 2 per cent sample of GDS cases completed during 1990-91. Evaluation involved Discriminant Analysis to find the most influential factors ...

One of the primary causes of endodontic failure is the presence of untreated canals. Although the maxillary first molar has been described as the most endodontically treated tooth, the canal configuration has been the least understood. The purpose of this article is to present, with the aid of several clinical ...

The case of a 12-year-old girl is reported, whose pretreatment radiograph demonstrated agenesis of two premolars and a canine and slow development of the contralateral premolars. A follow-up radiograph taken 1 year later showed initial mineralization of a tooth germ in the site of one of the apparently missing premolars. ...

This report describes the treatment sequence after traumatic loss of a maxillary central incisor in a 15-year-old patient. Following extraoral root canal treatment and initially successful replantation, the case presented 9 years later with complete root resorption. After augmentation with an autologous mandibular corticocancellous graft, a dental implant was placed ...

BACKGROUND: The authors present an interdisciplinary approach to treating bilateral impaction of mandibular second molars. CASE DESCRIPTION: A 22-year-old man had a bilateral deep horizontal impaction of his mandibular second molars. The mandibular third molars lay above and parallel to the second molars. After an orthodontic assessment, the authors decided ...

The first report of lateral maxillary expansion by separation of the maxilla, written by Angell and published in 1860, was discredited. Applying our present-day knowledge of the technique to the original documents indicates that the case history agrees in general with current observations. The arguments mounted against Angell, especially by ...

Six cases of asymptomatic dental twinning anomalies in the primary dentition are reported in 4205 school children. A clinical and radiographic presentation of the cases of fusion of primary incisor teeth is illustrated. This clinical entity has been found to appear with varied clinical and radiographic appearances. An association of ...

Nonsurgical treatment of 3 maxillary lateral incisors with dens invaginatus is reported. Invaginated teeth present technical difficulties with respect to their management because of complicated canal morphology. In the first case reported, apical abscess with incomplete root formation was found at the time of examination. Calcium hydroxide apexification provided favorable ...

This report is a clinical case of a 7-year-old child who presented right impacted second primary mandibular molar. This tooth was positioned inferior to the second premolar successor and a supernumerary tooth superior to the second premolar. Clinical examination did not reveal systemic diseases ot trauma in the facial region. ...

CASE REPORT: Talon cusp is an uncommon dental anomaly manifested as an accessory cusp-like structure on the crown of anterior teeth. This report describes two unusual cases of talon cusp. Case 1 showed bilateral anomalous cusps on the palatal aspects of maxillary supernumerary teeth, causing premature contact and tooth impaction. ...

STATEMENT OF PROBLEM: An extensive review of the published literature has revealed a wide divergence of opinion regarding the suitability of different post systems for endodontically treated teeth. As a result, the dentist has no clear guidelines concerning the selection of suitable post systems that will provide adequate retention while ...

A study of the literature reveals a variety of opinions on the potential for change in arch dimensions. The variations in sample sizes, treatment mechanics, and retention regimens may obscure relevant findings. These articles confirm some common findings, and a number of clinical cases are presented to illustrate these trends. ...

A rare case of a patient with aberrant root morphology in all the mandibular premolars is reported. A thorough review of the dental literature revealed little significant data concerning such cases, because much of the literature is concerned with variation in root canal morphology rather than variations in root morphology. ...

Often, the aesthetic dentist will place veneers to nonorthodontically reposition teeth. While this is a valid and beneficial treatment for many patients, the outcome is still compromised by improper tooth alignment. It is a pleasure to complete an interdisciplinary case where the tooth and arch alignment are ideally positioned. Restorative ...

Congenital absence of one or more teeth, hypodontia, is the most common developmental anomaly and is often accompanied by the presence of other tooth anomalies. In this case two Japanese sisters have several congenitally missing primary and permanent teeth and morphological abnormalities of maxillary first molars. One sister has transposition ...

A ten-year-old boy, who had the typical dental findings of dysosteosclerosis such as yellowish, hypoplastic teeth, retarded eruption, which upon eruption, decayed rapidly, is presented. To date this is the first known case reported with a congenital absence of the first permanent molars. Furthermore, SEM evaluation of the enamel and ...

This case report demonstrates the treatment of a Class III malocclusion, in a twelve-year-old girl, using a unique combination of a removable functional appliance, the "four-way sagittal" appliance and fixed appliance therapy. Efficient and effective correction of malocclusion was attained, following use of the "four-way sagittal" appliance. This appliance was ...

A case is presented where loss of an incisor tooth in a partial denture wearer created an aesthetic emergency. It was not possible to solve this simply by addition of a tooth to the existing denture. Reference to the previous dental history suggested that a further immediate solution might be ...

Both primary upper second molars were extracted from a young male patient. The left had a normal root pattern but the right had four well-defined roots. The accessory root appeared to be the mesiopalatal which had a distinctly rounded cross-sectional profile. The other roots had the typical form characteristic of ...

As one of the most demanding tasks facing the restorative dentist, planning and executing an occlusal rehabilitation should not be undertaken lightly. The stakes are high and failure is costly. Treatment planning decisions should be undertaken on the basis of scientific evidence, where this is available, or on the basis ...

A 35-year old Indian woman with eruptive onset of mollusca contagiosa with no underlying immunodeficiency who responded to etretinate therapy is reported.

Heredity is one of the possible factors associated with congenitally missing mandibular incisors. We report four cases--a mother and three daughters--in an attempt to examine this hypothesis. Different treatment modalities have been used to treat malocclusions stemming from this problem. The treatment philosophy of consolidating mandibular spaces and obtaining a ...

Four cases of bilateral bifid mandibular condyles are reported. A review of the literature showed that only four cases have been reported previously as incidental findings patients, while another four cases have been detected in post mortem material. Due to the minimal symptomatology, the diagnosis of a bifid condyle usually ...

A single maxillary central incisor in the midline is a rare developmental anomaly. The appearance of a single incisor in place of two teeth may occur as an isolated dental finding that can be related to fusion of two neighboring teeth or to agenesis of a tooth germ. However, the ...

Bilateral fenestration of the labial gingival tissue of the permanent mandibular central incisors is described. The situation was followed over a 2-year period with no treatment other than prophylaxis and oral hygiene instruction. The final outcome was an apical positioning of the gingival margin, which was lower than that of ...

External root resorption is one of the most exasperating and least understood clinical problems in orthodontics. Numerous studies have been conducted, attempting to establish the factors causing root resorption of permanent teeth. Considerable variation exists however, in the extent and distribution of root resorption, seen in the orthodontic treatment of ...

Management of traumatic injuries to the teeth is a challenge to the practising dentist. It has no prescriptive method for occurring, possesses no significant predictable pattern of intensity or extensiveness and occurring at times when dentists are least prepared for it. It may not only leave physical scars but also ...

OBJECTIVE: To review a series of cases of hypophosphataemic vitamin D resistant rickets. SUBJECTS INCLUDED: Seventeen cases, aged between 2 years 1 month and 15 years 9 months at first referral, and with an established diagnosis of vitamin D resistant rickets from twelve families were included in the review. Information ...

The procedure of extracting the deciduous canine to reduce the incidence of the unerupted palatally displaced canine was first described in 1951, and an article solely devoted to the technique appeared in 1959. The procedure then virtually vanished until 1981. A prospective study published in 1988 created the first widespread ...

We present two patients with post-traumatic mandibular asymmetry, caused by flaring of a fragment containing the mandibular angle in between two fractures. No occlusal disturbance was evident in either case. Instead of refracturing or ramus osteotomies, the asymmetry was corrected by transoral ostectomy of the mandibular angle with good aesthetic ...

Supernumerary teeth are common and can occur throughout the oral cavity. Molariform supernumerary teeth in the maxillary central incisor area have rarely been reported. This article reports the presence of mesiodentes in two siblings, one of whom exhibited an unusual molariform mesiodens. The clinical and radiographic appearance of the anomalies ...

The authors describe a clinical case of a palato-gingival groove on a maxillary central incisor with associated localized periodontal disease and pulp necrosis. The general clinician's initial diagnosis was incorrect; this led to incomplete treatment and subsequent loss of the tooth. Recognition of the palato-gingival groove is critical, especially because ...

The purpose of this work is to report a clinical case of removal of a fractured endodontic instrument in the root canal of a maxillary molar, when part of this fragment extended through the apical foramen. In the present case, many methods were tried without satisfactory results. Therefore, an alternative ...

Three cases of the juvenile form of paracoccidioidomycosis are reported. Emphasis has been given to the oral manifestations, particularly the periodontal involvement. The main periodontal findings were: generalized and progressive alveolar bone destruction leading to gingival recession with exposure of the tooth roots, and spontaneous tooth losses. The gingival mucosa ...

Children may present at a dental surgery for management of oro-facial injuries. Most general dental practitioners are able to handle straightforward cases but referral may be required for complex injuries. Successful healing following tooth avulsion depends on the amount of damage to teeth and supporting structures, emergency treatment, and follow-up ...

Fusion and gemination of permanent teeth are developmental anomalies of the dental hard tissues which may require endodontic and surgical treatment for functional, orthodontic or aesthetic reasons. Following a review of the dental literature on tooth fusion and gemination, a case of fusion of a maxillary central incisor and a ...

This article describes a series of 21 consecutive cases, each involving a solitary median maxillary central incisor; the patients were seen in the Department of Dentistry or the Victorian Clinical Genetics Unit, Murdoch Institute, at the Royal Children's Hospital, Melbourne, from 1966 to 1997. The spectrum of anomalies and associated ...

A rare finding of unilateral heterotopia of a mandibular third molar was most probably caused by primary and total dislocation of the tooth base. Other possible causative factors, such as a lack of space between the mandibular second molar and the mandibular ramus or a disproportion between the base and ...

Reimplantation failure of avulsed anterior teeth in an adolescent patient requires removal of the attempted-reimplanted teeth and consideration of several restorative options. These options may include a removable partial denture, as well as a transitional bridge or permanent fixed prosthesis. In all cases, the potential effects of the adolescent's expected ...

Treatment of a skeletodental Class II vertical growth problem, combined with a severe arch length deficiency in both arches, presents a challenging orthodontic problem.
