Postprocedural problems in an overdenture population: a longitudinal study.

This study reports on endodontic and other post-procedural problems experienced by overdenture patients from 1973 to 1996. There were 395 subjects enrolled in the study; 273 fulfilled the recall criteria. At recall, all subjects were examined by a single examiner, and appropriate maintenance care was performed. The 273 subjects had 666 abutments and 626 endodontically treated teeth; of these, 51 subjects had postprocedural problems in 81 teeth. Thus, 87.1% of the endodontically treated teeth had no postprocedural problems, and 12.9% had postprocedural problems. Of the subpopulation with postprocedural problems, the most common problem was endodontically treated teeth developing periradicular lesions (37.0%) because of recurrent caries causing loss of the restoration sealing the root canal. Twenty of the 30 teeth were successfully retreated. The next most common problem was vertical root fractures (30.9%), followed by vital teeth developing periradicular lesions (19.8%). Most of the failures could have been prevented by better oral hygiene. Vertical root fractures were statistically associated with abutments in the maxilla and opposed by natural teeth; protection of these abutments with thimble crowns could prevent fractures.

Primary teeth in adults--a pilot study.

Remaining primary teeth are occasionally found in adults. The cause and the long-term survival may vary. The aim of this investigation was to study the occurrence and condition of primary teeth in adults in a county in Sweden. All dentists in general practice were asked to send in radiographs showing remaining primary teeth in patients aged 18 years and more. The following variables were registered: 1) age, 2) gender, 3) year of exposure of the radiograph, 4) location of the primary tooth, 5) impaction of the permanent successor, 6) fillings or caries in the primary tooth, 7) amount of root resorption and 8) infraocclusion of the primary tooth. 35 dentists contributed with radiographs from 65 subjects showing 89 retained primary teeth. The most commonly found tooth was the second primary molar in the mandible, followed by the primary canine in the maxilla. Except for maxillary molars, most of the primary teeth showed a moderate degree of root resorption. No relationship was found between the degree of root resorption and gender, fillings/caries or infraocclusion. For the mandibular primary molars, there was a statistically significant correlation between root resorption and age. The mesial root of the molar in the mandible was more affected by root resorption than the distal, and the degree of root resorption of the mesial and distal roots was found to be closely correlated. Also, the results indicated a symmetrical pattern of root resorption in bilateral cases of remaining mandibular second primary molars.

Rapp-Hodgkin syndrome with palmoplantar keratoderma, glossy tongue, congenital absence of lingual frenum and of sublingual caruncles: newly recognized findings.

We report on a boy with Rapp-Hodgkin syndrome (RHS) or Rapp-Hodgkin ectodermal dysplasia. He had sparse, wiry, slow growing and uncombable hair, but no pili torti or pili canaliculi characteristic of RHS. He also had sparse eyelashes and eyebrows, and obstructed lacrimal puncta and epiphora. Bilateral bony external auditory canal stenosis led to hearing loss. The mouth was small with repaired bilateral cleft lip and palate. Oral manifestations included hypodontia, microdontia, unerupted mandibular premolars with well formed roots, large dental pulp spaces, enamel hypoplasia, multiple caries, glossy tongue, and congenital absence of lingual frenum and of sublingual caruncles including submandibular and sublingual salivary duct openings. Palmo-plantar keratoderma, unerupted premolars, congenital absence of lingual frenum, sublingual caruncles, glossy tongue, and pili canaliculi seen in the patient are newly recognized findings of this syndrome. Overlapping findings of RHS ectrodactyly-ectodermal dysplasia-clefting syndrome (EEC), and ankyloblepharon-ectodermal defects-cleft lip and palate syndrome (AEC) are discussed.

Response of the primary pulp to inflammation: a review of the Leeds studies and challenges for the future.

AIM: The purpose of this paper is to consider evidence for the early involvement of the pulp in primary molars following a proximal caries attack and to consider the evolution of ferric sulphate as the possible alternative to formocresol for pulp therapy in primary molars. Concerns have been expressed over the wisdom of using products containing formaldehyde in children and alternatives should be considered, even though there is no substantive data to support the claims of formocresol toxicity. Pulp therapy is still often required in the management of large proximal caries in primary molars. General dental practitioners often comment on the futility of restoring primary teeth with the common perception being that restorations more often than not fail in the primary teeth. One common cause is abscess formation following proximal restorations. The main reason why this occurs is that proximal restorations in primary teeth are often carried out without consideration being paid to the state of the pulp. We have shown in a series of studies in Leeds that pulp inflammation in primary molars precedes its exposure. Most primary molars where caries had involved more than half inter-cuspal distance manifested pulp inflammation involving the entire pulp horn, but rarely the root canal tissue. This would mean that in most primary teeth with proximal caries, which are indicated for a pulpotomy, the removal of the coronal pulp alone would render them free of inflammation. This would then bring into question the use of formocresol on an otherwise uninflammed radicular tissue, which has a viable blood supply. CONCLUSION: Pulp inflammation in primary molars sets in at an early stage of a proximal carious attack. Also, in most cases, a medicament that would achieve haemostasis, such as ferric sulphate, rather than achieve fixation of the tissues is all that would be required for the preservation of the primary tooth until exfoliation.

Influence of previous restoration of the tooth on prognosis of crowns with dowels.

Due to extensive loss of tooth substance the restoration of endodontically treated tooth requires intracanal dowels to give an efficient strength for the crown. The aim of our study was to investigate whether the previous type of restoration of the tooth, i.e. composite restoration with screw post versus one-piece dowel crown, has an effect on the prognosis of crowns with dowels. The material consisted of 111 single crowns and as a previous restoration there were 83 composite restorations with screw posts and 28 one-piece dowel crowns. The mean follow-up time was 78 months (range 6--163 months). The cumulative survival was 87% for one-piece dowel crowns and 84% for composite resins with screw posts. There were six root fractures, four losses of cement retention and one tooth extraction due to caries in crowns with previous composite resin with screw posts. In one-piece dowel crowns as a previous restoration there were two root fractures and one tooth extraction for periodontal reasons. In conclusion, it seems that the previous restoration has no marked effect on the prognosis of crowns with dowels when studying a composite resin restoration with screw post and a one-piece dowel crown.
