[Resorption of two upper incisors in a 14-year-old boy].

A 14-year-old boy was referred because of a slight swelling of the alveolar mucosa of the right central and lateral maxillary incisor. Radiographically, a well-circumscribed radiolucency was seen between the vital, but partially resorbed roots of the two incisors. Treatment consisted of careful enucleation, including removal of the two teeth. Histopathological examination showed a central giant-cell granuloma. Healing was uneventful. Additional examination for the presence of hyperparathyroidism was negative. During one year follow-up, no signs of recurrence have been noticed.

[Iatrogenic disease in pediatric dentistry. Report of a case].

The case history of a six-year-old girl who underwent endodontic treatment by a non recommended technique. It was decided to perform integral treatment anew, this time with techniques and materials adequate for the restoration and renewal of temporary dentition.

Multidisciplinary approach to a combined endodontic-periodontal lesion: a case report.

Esthetic dental treatment under ideal conditions is usually managed routinely without complication. Under such conditions, the periodontium is in a state of health and active periodontal therapy is not needed. However, in the presence of dental pathology, achieving our esthetic goals becomes exceedingly difficult. Correction of periodontal defects often leads to increased recession and interdental spaces, both difficult esthetic problems to manage. When existing periodontal defects are coupled with other pathologic entities, such as caries or trauma, the problems in trying to satisfy our treatment goals are compounded. A multidisciplinary approach is indicated and can provide excellent results.

Risk factors associated with atypical root resorption of the maxillary primary central incisors.

Maxillary occlusal radiographs of 233 children between 42 and 60 months old were examined for the presence or absence of atypical root resorption (ARR). In addition, the dental records of these children were examined to determine if an association existed between ARR, oral habits, documented trauma and overjet. Thirty-three (14.2%) of the patients had radiographic evidence of ARR of either maxillary primary incisor. Children with a positive history of both trauma to the incisors and oral habits had a statistically higher prevalence of ARR than those without either finding (P = .03). ARR was more prevalent as overjet increased, independent of trauma, and oral habits (P = .03). Furthermore, as the number of risk factors (large overjet, documented trauma, and oral habits) increased, the likelihood of developing ARR also increased.

The floor of the pulp chamber following pulpotomy.

The purpose of this study was to investigate the incidence of pulpal floor damage caused by operator error in a standard pulpotomy exercise, and to determine if this damage produced significant changes in dentin morphology and thickness at the base of the pulp chamber. One hundred and fourteen primary molar teeth were utilized in this study, 61 having pulpotomies and the remainder untreated. The dentin thickness in the furcation was measured on all the teeth and the pulpal floor morphology was examined using both light and scanning electron microscopy. The difference in thickness of dentin in the furcation of pulpotomized and non-pulpotomized teeth was not statistically significant. Less than fourteen per cent of pulpotomized teeth showed damage to the pulpal floor and this damage was only minimal in all cases. This study therefore suggests that damage to the pulpal floor during preparation is unlikely to be a factor contributing to failure of pulpotomies.

[A case of appendicular supplementary root with external root resorption].

The case of a lateral maxillary incisor with a supplementary root fractured by external root resorption, is presented. The role played for the periodontal disease is shown in the clinical and radiographic achievements, and their implications in the pulpal disease. Endodontic therapy was performed and the diagnosis confirmed in the specimen histological research.

Dental developmental status of southern Chinese girls in Hong Kong.

Dental developmental status of the permanent canines, premolars and second molars were studied in one hundred and two twelve-year-old Southern Chinese girls born and brought up in Hong Kong. Eruption of these teeth were defined as gingival emergence during the clinical examination while the root development was assessed from orthopantomographs. Root resorption pattern of the primary canines and molars were also studied with the aid of the orthopantomographs. Two-thirds of girls presented with permanent dentition stage. The root resorption patterns of the primary teeth were different from their order of exfoliation. The mandibular permanent teeth were in advanced in both eruption and root development than the corresponding maxillary teeth, except the first premolars.

[Resorption of roots of milk teeth treated by pulp amputation using formocresol].

Histological examination was carried out of milk molars involved by physiological or pathological resorption, i.e. accelerated, during treatment of pulp diseases by amputation using formocresol, and delayed in case of persisting milk teeth. The results showed that the histological pattern of accelerated resorption due to formocresol was not different from physiological resorption. Delayed resorption was associated with an evident repairing reaction in the resorption sinuses.

[Complete luxation of the upper incisor. Analysis of the mid-term results. Treatment of sequelae].

The study involved 18 children aged 7 to 13 years, who all benefited from early reimplantation and appropriate immobilisation. Radicular treatment appeared to have little influence and adverse results, especially early rhizalysis, were common (50% versus 30% of good results). In the event of failure, dento-facial orthopedic treatment, where indicated, may provide a cosmetically acceptable solution.

[Root resorption of mandibular second molars by impacted third molars. A case report with some reviews].

A case is presented here in which mandibular third molars resorbed second molars bilaterally 4 years 9 months after orthodontic treatment was finished. The initial problem was open bite, which was treated by non-extraction followed by a period for observing the third molars. During that period, the mandibular third molars moved mesially to resorb the roots of the second molars. The injured second molars were, therefore, extracted and the third molars were uprighted. During adolescence, third molars are erupting. When the posterior space is not enough for the third molars, they often erupt buccally or lingually, or impact distally toward the second molars and cause root resorption. It is suggested that the third molars should be observed carefully till they erupt or are extracted.
