Experience of wrong-site tooth extraction among Nigerian dentists

Objective

To report the experience of wrong-site tooth extraction among Nigerian dentists.

Study design

A self-administered questionnaire was distributed among a cross-section of Nigerian dentists. Information requested included personal experience on wrong-site tooth/teeth extraction and its after-effect, possible reasons for wrong-site tooth extraction and documentation of the event in patients’ case. Respondents were also asked if they were aware of any colleagues who had previously experienced wrong-site tooth extraction and possible legal implication of the event, and if they aware of the universal protocol for preventing wrong site, wrong procedure, and wrong person surgery.

Results

Twenty-two (13%) of the respondents reported having extracted a wrong tooth. The event occurred within 5 years after graduation in most cases. Most respondents (53.6%) informed the patient immediately after the event. Only 68% of the respondents documented the event in patient’s case record. Most common reasons for wrong-site tooth extraction were heavy workload, presence of multiple condemned teeth and miscommunication between dentists. Fifty-five percent of respondents were aware of a colleague who had extracted a wrong tooth. The most probable legal implication of wrong-site tooth extraction according to the respondents was litigation by the patient. Only 25% of dentists were aware of a universal protocol for preventing wrong-site surgery.

Conclusions

Wrong tooth/teeth extraction is not an uncommon event in the studied environment. The need to be familiar with universal protocol on wrong-site surgery and its legal implications are highlighted.     

Management of intruded primary teeth after traumatic injuries

Intrusions occur frequently in the primary dentition. It has been reported that conservative treatment of the intruded primary tooth is preferred if the apex is away from the permanent tooth germ. Conservative treatments include waiting for spontaneous re-eruption, and surgical re-positioning and fixation. Few papers have been published in Japan comparing the prognoses of intruded primary teeth between these two different modes of treatment. Therefore, optimal treatment for intruded primary teeth has been a topic of controversy among clinicians. The aim of this study was to compare the outcomes of intruded primary teeth between these two modes of treatment. Moreover, we examined the issue of treatment of choice for intruded primary teeth. The subjects consisted of 17 children referred to the Hiroshima University Hospital Department of Pediatric Dentistry for the treatment of 21 intruded primary teeth. Fourteen teeth were allowed to spontaneously re-erupt (group W), and 7 teeth were repositioned and fixed (group R). Antibiotic therapy and irrigation were performed in all intruded teeth. Treatment outcomes were evaluated using the following parameters: re-eruption, pathological pulp changes, increased mobility, discoloration, pulp canal obliteration, pathological root resorption, and disturbances of permanent teeth. In group W, root canal treatment or extraction were not performed since re-erupted teeth reveal no signs of infection. On the other hand, in group R, 57% of teeth required endodontic treatment or extracted due to signs of infection. The result showed treatment outcomes in group R were worse than those in group W. Our study indicates that most intruded primary teeth re-erupt with a favorable prognosis. Therefore, observation with irrigation and antibiotic therapy should be the treatment of first choice.     

Brazilian dentists' knowledge regarding immediate treatment of traumatic dental injuries

Abstract –  The objective of this study was to assess the knowledge of dentists working in the city of Tubarão, southern Brazil, about the immediate treatment of traumatic dental injuries. A cross-sectional study was carried out involving all dentists who were working in the city in 2004 ( n  = 108). Data were collected through self-applied questionnaires with questions about sex, time elapsed since graduation, whether the dentists had attended postgraduate courses and also four questions about traumatic dental injuries in which the dentists selected the best answer. The response rate was 86.1%. For the two questions related to dental avulsion, 36.6% and 16.1% of professionals respectively, chose the correct answer according to the literature. For the question related to coronal fracture, 75.3% chose the correct answer. For the questions related to an incident without dental avulsion or fracture, 73.1% chose the correct answer. Time elapsed since graduation was the only variable statistically associated with the correct answer for the question related to coronal fracture. A significantly greater number of professionals with ≤10 years of experience chose the correct answer when compared with professionals with >10 years experience ( P  < 0.001). It can be concluded that the great majority of professionals would not intervene according to the literature in the cases of avulsion. Less time elapsed since graduation was statistically associated with the correct answer in the coronal fracture case.     

Interproximal reduction of teeth: Differences in perspective between orthodontists and dentists

Objective:To determine if interproximal reduction of teeth (IPR) is perceived differently by orthodontists and general dentists.Materials and Methods:A Web-based survey containing statements about IPR was developed and randomly distributed to orthodontists and general dentists.Results:The majority of orthodontists and general dentists strongly agreed that IPR is a minimally invasive procedure that poses little risk for the development of interproximal decay. However, general dentists were more likely to perform post-IPR polishing and to apply topical fluoride than are orthodontists (P < .0001). A greater percentage of orthodontists strongly believed that the esthetic and occlusal benefits of IPR outweigh the potential risk of tooth decay when IPR was performed (P < .0001). A greater percentage of general dentists were hesitant to perform IPR, despite research supporting that IPR has little negative effect on the health of teeth.Conclusions:The results of this study disproved the null hypothesis that orthodontists and general dentists share similar views regarding the use of IPR during orthodontic treatment. General dentists were more conservative in their views of IPR and were less comfortable with performing IPR as a routine procedure. General dentists felt more strongly about the importance of post-IPR polishing and application of topical fluoride. Orthodontists were more likely to have researched the long-term effects of IPR on the health of teeth and therefore felt more comfortable performing IPR during orthodontic treatment.     

Traumatic injuries in the primary dentition

Abstract  – As a support for the guidelines published in 2001, a review of the literature was carried out using the evidence-based approach in order to update the state of the art regarding epidemiology and treatment of traumatic dental injuries in the primary dentition. An online search in Medline, and a review of expert literature, lead to the conclusion that most luxation injuries heal spontaneously, and unless more conclusive evidence is available, conservative treatment of acute dental trauma for preschool children is suggested. Pain control, the dentist's ability to cope with the child's anxiety, and follow-up instructions in oral hygiene techniques will allow many primary teeth that are currently lost at the time of injury to be saved.
