Garre's osteomyelitis of an unusual origin in a 8-year-old child. A case report.

Garre's osteomyelitis is a type of chronic osteomyelitis that primarily affects children and adolescents. Although the disease is well described in the dental literature and is usually associated with an odontogenic infection resulting from caries, a number of other causative factors have been occasionally reported, such as a dental extraction or a mild periodontitis. There have also been cases of unknown aetiology. This paper describes a case of Garre's osteomyelitis in an 8-year-old child, in whom the condition arose following a local periodontal infection in an ectopically erupting first permanent molar that was in infraocclusion. The lesion remained unresolved for a period of over 6 months as a result of misdiagnosis, following a number of unsuccessful treatment attempts. Identification of the true cause and treatment through periodontal surgery resulted in lesion resolution and resolved the diagnostic problem. Dentists should be aware that the periodontium may be a potential source of infection for Garre's osteomyelitis in children, particularly in the presence of ectopically erupting posterior teeth. In such cases, periodontal treatment should be sufficient to treat the disease and extraction of the tooth involved may not be necessary.

Profile of non-nutritive sucking habits in relation to nursing behavior in pre-school children.

Although a number of investigators have studied the prevalence and etiology of non-nutritive sucking habits in children, no consensus exists among dental and medical experts in respect to the contributing factors and preventing behaviors. Furthermore, changes in the rearing practices of children make management of such habits even more complicated. The purpose of the present study was to investigate finger and pacifier sucking habits among pre-school children, and its possible relationship to nursing behavior. Parental attitudes towards sucking habits were also registered. Questionnaires were sent to parents of 600 children, three to five years old, following an oral examination in a private office. Children attended kindergartens that were randomly selected from the area of Athens, Greece. Questions regarding the nursing patterns-breast or bottle feeding-characteristics of finger and pacifier sucking habits, parental attitudes towards sucking habits, as well as recommendations of the pediatricians were included. Three hundred and sixteen questionnaires were returned by parents. Results indicated that pre-school children discontinued a pacifier sucking habit earlier compared to a finger habit. Pacifiers showed a preventive effect against finger sucking, since only 2% of the sample examined practiced both habits. Breast feeding was not clearly associated with sucking habits; however, long bottle feeding periods were related with decreased finger sucking and high figures of pacifier sucking. The majority of pediatricians were not in favor of an intervention in breaking a finger sucking habit of the child.

Management of intrusive luxation injuries.

Traumatic intrusion of permanent teeth is a relatively infrequent but serious type of dental injury, due to the complicated picture it involves. Various treatment approaches have been suggested, so far, regarding management of intrusive luxation. Techniques aiming to reposition the intruded tooth include observation for spontaneous reeruption, surgical as well as orthodontic repositioning. However, development of complications such as pulp necrosis, inflammatory root resorption, replacement resorption and ankylosis and loss of marginal bone support makes selection of the most favorable technique controversial. In this paper, a critical review of the existing treatment modalities is attempted and treatment approaches based on diagnostic parameters that are indicative of the severity of an intrusive injury are presented. Recommendations are made after taking into consideration experimental and clinical study findings and observations from other author's and our own clinical experience. Two cases of intrusive luxation in children are presented and management of the dental injuries as well as the complications which occurred are being discussed.

A typical Hallermann-Streiff syndrome in a 3 year old child.

Hallermann Streiff syndrome is a rare congenital disorder characterized by dyscephaly, dental anomalies, proportionate nanism, hypotrichosis, cutaneous atrophy limited to the head, bilateral congenital cataracts and bilateral microphthalmia. Despite the marked craniofacial characteristics and oral findings, a relative lack of reports in the dental literature has been noted. In this article, a review of the literature regarding the general clinical features and differential diagnosis is presented. A case of a 3-year-old female is reported with special consideration on the management of her dental problems under general anesthesia. The anesthetic risks of such a procedure as well as the prognosis of her dental development are being discussed.

A review of dentine-bonding agents and an account of clinical applications in paediatric dentistry.

The need for dental materials which bond to all hard tissues of the tooth is an obvious one. The technique of enamel acid etching has made adhesion to enamel possible. In addition, extensive research has allowed the development of dentine-bonding agents, materials that are claimed to bond to dentine. The first and second generation of these products, despite their early success and popularity, pose several problems, including a weak and unstable bond in the oral environment. During the last decade, a number of systems, known as the third generation of dentine-bonding agents, have been marketed. They base their bonding ability on the utilization of the organic part of a pre-treated dentine. In vitro studies have reported significantly higher bond strength, and reduced microleakage and marginal gap formation. Biocompatibility and toxicity studies have demonstrated no direct harmful effect on the pulp. Clinical trials have shown promising clinical performance. These products can offer treatment alternatives in paediatric dentistry; for example, for teeth affected by amelogenesis imperfecta or local hypoplasia, for anterior teeth extensively damaged by decay or trauma, and for teeth with hypersensitive dentine. However, the dentist should be cautious using these systems because, for most of the products, the permanence of the bond in the oral environment has not been extensively studied.

[Dental needs of school children of the district of Athens].

The high rate of tooth destruction of Greek children due to caries has been shown from several studies. The dental needs, the type and the cost of treatment of these children and especially those of the district of Athens have not been evaluated before. The purpose of this study was to determine these needs and evaluate the aforementioned parameters. The results of this study have shown that from the 1166 children aged 6-12 years of age, 71.6% have some problems with caries. There has been an increasing rate of the total dental needs of primary and permanent teeth from the age of 6 through the age of 12, for both sexes, although the dit index decreased after the age of 8 years. This finding partially shows that the intervention and the degree of treatment provided was very minor since the problem continued to the permanent dentition with the teeth becoming decayed immediately after they erupt. However, might be considered proof of the above the finding that the dental needs of the first permanent molar was only 1.4% at the age of 6 years while at the age of 12 years increased at 66.6%. The oral hygiene status of the children was moderate to bad for 85.9% of them and only 18.5% had a good oral hygiene. 36 per cent of the children had some orthodontic problem while a 7.4% of the total number of the children revealed crossbites. The cost of treatment and prevention per child was calculated as well and it was found that 68.7 (U.D.T.) units of Dental Treatment or 12.365 drs are required. The results of this study have shown the type the degree and cost of treatment of the dental needs of these children and the necessity for immediate intervention of treatment and comprehensive preventive measures.

[Secondary caries as a problem].

A large number of the all operative work performed in a dental office is amalgam fillings. Secondary caries continuous to be a serious problem although amalgam has been improved to a large extent. All efforts that have been made to eliminate the problem of secondary caries associated with amalgam fillings have not been very successful so far. There is always a lack of permanent seal between restorations and the prepared tooth surfaces so that microleakage always exists. The purpose of this paper was to search the literature on the subject and find ways and attempts that have been made on the elimination of secondary caries. On the other hand was aimed to present and discuss the application of fluorides into the cavity preparation as a preventive method of eliminating secondary caries as well as the possible effects of fluorides on the dental pulp if they exist. The literature gives a lot of information on the subject and fluorides in the cavity before the filling insertion seems to be a safe and approved method against secondary caries. Regarding the effect of fluorides on the pulp it is indicated that when the proper agent and technique is used there is no any deleterious effect and the method is not contraindicated.

[Indications and limitations of sealants use in incipient carious lesions].

The application of occlusal sealants has been well established as an effective and safe measure in preventing dental caries since many years. Although the use of pit and fissure sealants on incipient occlusal carious lesions has been suggested as a safe procedure, several points and questions still exist. The aim of this paper was to search the literature present the pertinent studies and critically evaluating the results to give some answers for the better use of sealants on occlusal incipient carious lesions. The clinical practitioner is going to find some answers in this paper on: 1) whether there is a need for using sealants on incipient lesions, 2) what might be the progress of an undetected incipient lesion sealed with a sealant in terms of the overall benefit or dentiment to the tooth and 3) in the case where there is a detectable lesion, what might be the efficacy of the sealants in consolidating, retarding, or preventing the progress of such a lesion. Most of the studies agree that incipient lesions at an early stage and before a cavitation occurs should sealed and followed closely. Regarding the therapeutic use of sealants there is no a definite or conclusive answer. The practitioner should be very concious and skeptical since there are many unanswered questions and not enough data supporting such a procedure.
