Knowledge and attitude of Jordanian school health teachers with regards to emergency management of dental trauma.

The purpose of this study was to assess, by means of a self administered structured questionnaire, the level of knowledge of school health teachers in northern Jordan with regards to the immediate emergency management of dental trauma. The questionnaire surveyed teacher's background, Knowledge of management of tooth fracture, avulsion, and loss of consciousness, it also investigated teacher's attitudes, and self assessed knowledge, as well as knowledge of availability of emergency services in Jordan. The sample consisted of all school health teachers in northern Jordan (220) who attended an oral health education course held by the Jordanian dental association. Only 190 were included in the survey. Sixty-three percent were females, 44% were in their twenties, and 43% in their forties. Their school health teaching experience ranged from 1 to 7 years. Only 20% were officially trained in school health. Less than half of the teachers received first aid training only once in their teaching career, not necessarily as part of school health training. Only 10 teachers were trained in dental first aid, and more than half had a previous experience with handling dental trauma in children. Overall the teachers' knowledge with regards to the emergency management of the trauma cases presented in the report was deficient. Chi-square test showed that, the difference in their responses to the knowledge part of the questionnaire was not statistically significant with regards to age, gender, years of teaching experience, first aid training, or number of seen trauma cases. Generally, the attitude was positive, most teachers wanting further education on the topic, however those who were trained in first aid, thought they were able to give proper action when needed in cases of trauma (P = 0.026). Most teachers were unsatisfied with their level of knowledge, and only 30% knew of the availability of after hour emergency services for dental trauma. The present report indicated the gross lack of knowledge among school health teachers with regards to dental trauma emergency management. Educational programs to improve the knowledge and awareness of this group of adults, who are usually the first line of advice in case of dental trauma in schools, are mandatory. These programs should be properly designed to insure that proper information is retained with a positive effect on attitude, and self assessed competence.

A controlled clinical study of amalgam restorations: survival, failures, and causes of failure.

The survival and modes of failure of amalgam restorations were investigated retrospectively. 2660 Class I or II lesions were restored and evaluated yearly or half-yearly for failures during the 30- to 84-month follow-up. Restorations with unacceptable margins were not counted as failures if no traces of secondary caries could be seen. 8% of the restorations were lost because of patient drop-out. Of the remaining restorations, 1% was replaced due to primary caries. Of the remaining number (2431), 9% failed because of all other reasons. The leading mode of failure was bulk fracture (4.6%), followed by tooth fracture (1.9%), and marginal ridge fracture (1.3%). For all other reasons, 0.8% of the restorations failed. Only two restorations were replaced because of secondary caries. The alloy selection in both conventional and high-copper categories significantly influenced the survival of the restorations for reasons directly related to the restoration.

[The management of 126 cases of posterior cracked crown of tooth and its effective observation].

OBJECTIVE: To detect the treatment and effect of posterior cracked tooth. METHODS: 162 posterior cracked teeth of 158 cases, including enamel fissure and dentin fissure, all there cases undergone the synthetical treatment and follow up in different period, the longest observation period was 2.5 years. RESULTS: The healing and improved rate of 162 cracked teeth 90.74%. Among cases of failure, we have founded 6 cases of acute pulpitis (3.7%), 3 cases of alveodental abscess (1.85%), 2 cases of chronic apical periodontitis (1.24%), 4 cases of tooth fracture (2.4%). CONCLUSION: Cracked tooth was caused by multiple factors. Early diagnosis, synthetical treatment, and follow up in different period are 3 main factors in treatment.

Meth mouth: a review of methamphetamine abuse and its oral manifestations.

Illicit methamphetamine use is reported widely by news media and discussed increasingly among scholars, clinicians, and members of civic and law enforcement organizations and legislative bodies. This article examines the phenomenon of methamphetamine abuse, including its extent, its effects on both users and society, and its implications for dentistry. Meth mouth refers to a pattern of oral signs and symptoms of methamphetamine abuse, thought to include rampant caries and tooth fracture, leading to multiple tooth loss and edentulism.

Treatment of root fracture by CO2 and Nd:YAG lasers: an in vitro study.

The purpose of this in vitro study was to use scanning electron microscopy and polarized light microscopy to evaluate the feasibility of using either the CO2 laser or an Nd:YAG laser in combination with air/water surface cooling to effect fusion of fractured tooth roots. The experimental unit consisted of 81 single-rooted teeth, each with an induced root fracture. Fifty-six teeth that had been reapproximated in dental stone and 25 teeth that had been reapproximated with C-clamps were assigned to untreated control groups or groups for treatment using CO2 and Nd:YAG lasers. Laser treatment consisted of multiple passes along the line of fracture, which was inspected using a dissecting microscope after each pass until a visual indication of fusion or irreparable damage resulted. Scanning electron microscopy evaluation of the treated lines revealed heat-induced fissures and cracks, areas of cementum meltdown and resolidification, crater formation, and separation of cementum from underlying dentin. In no instance-regardless of reapproximation technique, laser type, energy, and other parameters-did the treatment effect fusion of the fractured root halves.

Ceramic inlay systems: some clinical aspects.

Due to their inertness and unsurpassed aesthetic properties, ceramic materials are increasingly used as inlay materials. Based on a questionnaire, the frequency and character of complications related to ceramic inlay therapy were assessed and some important pitfalls and clinical relevant factors discussed. A majority of the dentists performed between 1 and 10 ceramic inlays per month using several different ceramic materials. As many as 85% of the dentists had observed complications in connection with ceramic inlays. Most frequency reported was hypersensitivity of a transient nature (15%). The material revealed an overall inlay fracture frequency of 5%, but the individual variations were high. Tooth fracture, loss of retention and other complications such as secondary caries, endodontic envolvement, colour mismatch and a surface and edge deterioration occurred with a varying but lower frequency. Failure analysis revealed a large number of causative factors among which cavity and inlay design, bonding procedures, selection of luting material and proper case selection were regarded as the most important. Due consideration to the strength of remaining tooth substance was found to be important in reducing the problem of hypersensitivity and the risk of tooth and inlay fracture.

Orthodontic extrusion of subgingivally fractured incisor before restoration. A case report: 3-years follow-up.

Orthodontic forced eruption may be a suitable approach without risking the esthetic appearance in tooth fracture below the gingival attachment or alveolar bone crest. Extrusion of such teeth allows elevating the fracture line above the epithelial attachment and so the proper finishing margins can be prepared. Restoration after orthodontic eruption may present a more conservative treatment choice in young patients compared with the prosthetic restoration after extraction. This case describes a multidisciplinary approach using the orthodontic forced eruption facilitating the composite restoration of a fractured upper permanent central incisor.

Consequences of posterior cusp fracture.

Although posterior cusp fracture occurs frequently, its consequences are not well-delineated. This study recorded short-term outcomes (distribution of fractured teeth and cusps, fracture severity, and treatment received up to two years postfracture) for 517 fractured teeth from 498 subjects at a large group practice. Maxillary and mandibular tooth fractures occurred with similar frequency. In the maxillary arch, first and second molars and premolars fractured with roughly the same frequency; premolar fractures were more severe. In the mandible, first molars accounted for approximately 50% of all fractures and were most likely to be severe fractures. Nonholding cusps were more likely to fracture in both arches. Proportions of fractured teeth receiving "catastrophic" treatment were low (3% extraction; 4% endodontic treatment) and the large majority of fractured teeth were treated in a single visit using direct restorative materials. A knowledge of the relatively small proportions of fractured teeth that suffer serious consequences and the tooth-specific distributions of cusp fracture should help dentists and patients to make informed decisions regarding preventive restorative intervention prior to fracture.
