Pain prediction for preventive non-operative management of dentinal caries in primary teeth in general dental practice.

OBJECTIVES: To provide a pain-predictive model for the non-operative management of carious deciduous teeth from the analysis of data from a retrospective analysis of clinical case notes of children regularly attending two general dental practices and receiving preventive care. DESIGN: A clearly defined protocol was used to determine the fate of deciduous teeth diagnosed as carious into dentine but symptomless and left unrestored from the sequential examination of the clinical records of 480 children attending at least annually. RESULTS: The age of the children at the first visit when carious teeth were diagnosed ranged from 008 to 12.3 years, with the majority of children (243/480) presenting by 6 years of age. In all, 250 teeth from 162 children were extracted because of pain or became painful and were treated. The remaining 318 children did not report pain on subsequent visits. The strongest predictor of pain was age on diagnosis, the other factors being tooth type and extent of the cavity when first seen. Data from the present study provides a model that enables a child with deciduous caries to be placed into one of six pain-predictive groups associated with a risk of pain or infection if the teeth are not restored but provided with preventive care only. CONCLUSIONS: In these patients, the majority of unrestored carious deciduous teeth remain symptomless until shed. A higher risk of subsequent pain or infection was associated with the development of caries in younger patients, disease extending beyond single surfaces, and disease in lower deciduous molars. The results provide evidence to aid the treatment planning of carious deciduous teeth in children receiving regular preventive dental care.

Endodontics: Part 3. Treatment of endodontic emergencies.

The swift and correct diagnosis of emergency problems is essential when providing treatment, especially in a busy dental practice. A diagnosis must be made and appropriate treatment provided in usually just a few minutes. The sequence considered here encompasses problems presenting before, during and after dental treatment. Various diagnostic aids are considered, and some unusual presenting conditions discussed.

Patient expectations of emergency dental services: a qualitative interview study.

OBJECTIVE: To describe the expectations of walk-in patients seeking emergency dental care out-of-hours. BASIC DESIGN: Consecutive patients attending two emergency dental clinics at weekends were interviewed prior to seeing the dentist. The audio-recorded interview transcripts were analysed using the "framework" method of applied qualitative data analysis. SUBJECTS AND SETTING: Forty-four walk-in emergency dental patients at a community-based dental clinic and a dental hospital emergency clinic at the weekend. RESULTS: In addition to symptom relief, the main desired outcome for emergency dental patients may be informational and psychological--especially reassurance that the problem is not serious, and reduced uncertainty about the cause of the pain. In general, patients' stated expectations for specific treatments (such as antibiotics, or tooth extraction) were not absolute: rather, they implied these expectations were conditional upon the dentist deciding they were necessary. CONCLUSIONS: Emergency dental services, some of which are still dominantly treatment-focused, should reflect that many emergency dental attenders want advice and reassurance as much as relief from symptoms. This reinforces the importance of effective and sympathetic dentist-patient communication within emergency or out-of-hours consultations. It also implies that dentists' skills in listening, explaining and reassuring should be captured in any patient satisfaction or outcome measure designed for this patient group.

The effectiveness of out-of-hours dental services: I. Pain relief and oral health outcome.

OBJECTIVE: To compare the effectiveness of four types of out-of-hours emergency dental service, including both 'walk-in' and telephone-access services. BASIC DESIGN: Questionnaire survey of patients attending weekend emergency dental services, with measurement of self-reported oral health status and dental pain (at attendance and follow-up) and retrospective judgements of change in oral health status. SETTING: Two health authorities in South Wales, UK. SUBJECTS: A total of 783 patients who completed questionnaires at attendance, and 423 who completed follow-up questionnaires. RESULTS: For patients who saw a dentist there were no consistent differences in the effectiveness of the four services, whether measured as pain relief, oral health gain or using patients' retrospective transition judgements about feeling better after their episode of emergency dental care. The proportion of patients reporting no improvement (transition judgements), either an hour after or the day after seeing the dentist, was surprisingly high (30-40% and 23-38% respectively). Although the 'rotas for all' - a telephone-access GDP-provided service for both registered and unregistered patients - achieved both the highest reductions in pain scores and the greatest improvements in dental health status between attendance and follow-up, this effect may reflect health gains due to care received after the episode of emergency dental care. CONCLUSIONS: Neither the setting where emergency dental patients are seen, nor the type of dentist who sees them, appear to have any significant effect on patient-reported health outcomes. Although further exploration of the factors that predict poor pain relief or low oral health gain is required, future research on these services should focus on the process of care and accessibility.

Autoextraction in a child with autistic spectrum disorder.

Many children with mild/moderate autistic spectrum disorder (ASD) receive care in general dental practice. We report a seven year old boy with ASD presenting with dental pain who auto-extracted one of his deciduous canines. Children with ASD may have hyposensitivity to pain and can exhibit unusual forms of self-injurious behaviour.

A randomised controlled trial of clinical outreach education to rationalise antibiotic prescribing for acute dental pain in the primary care setting.

OBJECTIVE: To assess the effect of educational outreach visits on antibiotic prescribing for acute dental pain in primary care. STUDY DESIGN: RCT. SETTING: General dental practices in four health authority areas in Wales. SUBJECTS AND METHODS: General dental practitioners were recruited to the study and randomly allocated to one of the three study groups (control group, guideline group or intervention group). Following the intervention, practitioners completed a standardised questionnaire for each patient that presented with acute dental pain. INTERVENTIONS: The control group received no intervention. The guideline group received educational material by post. The intervention group received educational material by post and an academic detailing visit by a trained pharmacist. The educational material included evidence-based guidelines on prescribing for acute dental pain and patient information leaflets. MAIN OUTCOME MEASURES: The number of antibiotic prescriptions issued to patients presenting with dental pain and the number of 'inappropriate' antibiotic prescriptions. Antibiotics were considered to be inappropriate if the patient did not have symptoms indicative of spreading infection. RESULTS: A total of 1,497 completed questionnaires were received from 23, 20 and 27 general dental practitioners in the control, guideline and intervention group respectively. Patients in the intervention group received significantly fewer antibiotic prescriptions than patients in the control group (OR (95% CI) 0.63 (0.41, 0.95)) and significantly fewer inappropriate antibiotic prescriptions (OR (95% CI) 0.33 (0.21, 0.54)). However, antibiotic and inappropriate antibiotic prescribing were not significantly different in the guideline group compared to the control group (OR (95% CI) 0.83 (0.55, 1.21) and OR (95% CI) 0.82 (0.53, 1.29) respectively). CONCLUSIONS: Strategies based upon educational outreach visits may be successfully employed to rationalise antibiotic prescribing by dental practitioners.

Thermal sensitivity of endodontically treated teeth.

CASE REPORTS: The problem of thermal sensitivity following non-surgical root-canal treatment is explored and case reports are presented. Possible causes for post-treatment discomfort from endodontic and restorative aetiologies are discussed, as are the mechanisms to explain the patients' painful experiences. Treatment of this problem may vary from the simple replacement of a defective restoration to a more extensive non-surgical retreatment of the case, despite radiographic evidence of an acceptable root filling and normal periradicular tissues.

Determination of endotoxins in caries: association with pulpal pain.

AIM: The aims of this study were: (i) to determine the presence or absence of endotoxins in the superficial and deep layers of carious lesions of symptomatic and asymptomatic teeth with vital pulps; (ii) to quantify the amount of endotoxin present; and (iii) to associate the presence of endotoxins with the acute pulpal pain derived from the irreversible pulpitis. METHODOLOGY: Two specimens of carious dentine were taken under aseptic conditions from symptomatic teeth with irreversible pulpitis (n = 9) and asymptomatic teeth with reversible pulpitis (n = 11). The first specimen was taken from a layer of superficial caries and the second from a deeper one. Sound dentine was also collected from intact teeth without restoration and used as a noncarious control group (n = 4). During the patient sampling procedure an effort was made to collect an equal quantity of caries and sound dentine in all cases (approximately 6 mg). The extraction of endotoxins was performed using the Phenol-water method. The assay and quantitative determination of endotoxins was performed by the Quantitative Chromogenic test using Limulus Lysate. Data were analysed statistically using either independent or paired t-tests. RESULTS: The results indicated that endotoxins were present in the superficial and deep layers of caries of all symptomatic teeth with irreversible pulpitis (0.15078 and 0.12111 ng mL-1, respectively), with significantly greater amount (P < 0.01) in the superficial compared to the deep layer. Endotoxins were found in superficial and deep layer of caries of all asymptomatic teeth with reversible pulpitis (0.12091 and 0.07163 ng mL-1, respectively), with significantly greater amounts (P < 0.001) in the superficial compared to the deep layer. The results also demonstrated that significantly greater concentrations (P < 0.005) of endotoxins were present in the superficial carious layer of symptomatic compared with asymptomatic teeth (0.15078 and 0.12091 ng mL-1, respectively). Likewise, significantly greater amounts (P < 0.001) of endotoxins were present in the deep carious layer of symptomatic compared with asymptomatic teeth (0.12111 and 0.07163 ng mL-1, respectively). In sound dentine no endotoxins were detected. CONCLUSIONS: This study demonstrates that endotoxins are present in carious lesions of symptomatic and asymptomatic teeth. The amount of endotoxin was significantly greater in the superficial compared to the deep layer of carious dentine. More endotoxins are present in caries of painful teeth compared with those without symptoms.

Quantitative analysis of substance P, neurokinin A and calcitonin gene-related peptide in pulp tissue from painful and healthy human teeth.

AIM: The purpose of this study was to investigate the levels of substance P (SP), neurokinin A (NKA) and calcitonin gene-related peptide (CGRP) in painful and healthy human dental pulps. METHODOLOGY: Forty-six samples of pulp tissue were collected from extracted or endodontically treated painful teeth and 20 from clinically healthy teeth extracted for orthodontic reasons. All pulp samples were boiled in 0.5 m acetic acid for 10 min, centrifuged and the supernatant collected. SP, NKA and CGRP levels were measured using radioimmunoassay. RESULTS: Substance P and CGRP were present in all samples and NKA was detected in 96% of the pulps. CGRP was present in much higher concentrations than SP and NKA in both painful and non-painful teeth. The painful teeth had significantly higher concentrations of SP (P = 0.02), NKA (P < 0.001) and CGRP (P = 0.03) than non-painful teeth. The concentration of CGRP was significantly higher in the pulps of smokers compared with non-smokers (P = 0.02). CONCLUSIONS: Elevated levels of these neuropeptides in pulps from painful teeth indicate that they may play an important role in the process of pulpal inflammation and pain. Further investigation of the association between these neuropeptides and pulpal status may help to improve our understanding of pulpal inflammation and dental pain.

Prodromal herpes zoster--a diagnostic challenge in endodontics.

This case report highlights the diagnostic challenge that herpes zoster represents if pain develops in the prodromal stage. A 58-year-old male presented with pain in the left maxilla. The symptoms had lasted for 7 months. The first premolar had been extracted soon after the onset, and the second premolar root filled shortly thereafter. Symptoms were experienced as sudden pain attacks lasting for several hours and analgesics gave some pain relief. Clinical examination showed that the second premolar was tender to percussion. No sinus tract or swelling were present. Radiographic examination showed previously root-filled second premolar and first molar teeth, and no evidence of apical pathosis. Due to the uncertainty about the quality of the root filling in the second premolar and incomplete root filling in the first molar, retreatment was started prior to prosthetic treatment in the region. The pain continued and became more intense during the treatment. A diagnosis of herpes zoster was determined, when an acute attack with oedema and vesicles occurred, 2 months after retreatment was started. In the present case, therefore, the primary attack presented itself after months and the herpes zoster diagnosis could not be made until then. points. Key learning points. * A long lasting prodromal stage is an unusual event. * Symptoms combined with inadequate technical standard of root fillings may confuse the diagnostics. * No available data support or suggest the use of antiviral treatment as a diagnostic tool.

Microorganisms from canals of root-filled teeth with periapical lesions.

AIM: The objective of the present study was to identify the microbial flora within root canals of teeth with failed root-canal treatment and to determine the association of the various species with clinical features. METHODOLOGY: Sixty root-filled teeth with persisting periapical lesions were selected for this study. During nonsurgical endodontic re-treatment, the root-filling material was removed and the canals were sampled. Microbial sampling, isolation and species determination were performed using advanced microbiological techniques for anaerobic species. The association of microbiological findings with clinical features was investigated. RESULTS: Microorganisms were recovered from 51 teeth. In most cases, one or two strains per canal were found. Of the microbial species isolated, 57.4% were facultative anaerobic species and 83.3% Gram-positive microorganisms. Enterococcus faecalis was the most frequently recovered bacterial species. Obligate anaerobes accounted for 42.6% of the species and the most frequently isolated genera was Peptostreptococcus. which was associated with clinical symptoms (P < 0.01). Significant associations were also observed between: (a) pain or history of pain and polymicrobial infections or anaerobes (P < 0.05): (b) tenderness to percussion and Prevotella intermedia/P. nigrescens (P < 0.05); (c) sinus and Streptococcus spp. (P < 0.001) or Actinomyces spp. (P < 0.01); (d) coronally unsealed teeth and Streptococcus spp. or Candida spp. (both with P < 0.01). CONCLUSION: The microbial flora in canals after failure of root-canal treatment were limited to a small number of predominantly Gram-positive microbial species. Facultative anaerobes, especially E. faecalis, were the most commonly isolated microorganisms, however, polymicrobial infections and obligate anaerobes were frequently found in canals of symptomatic root-filled teeth.

An investigation of language used by children to describe discomfort during dental pulp-testing.

AIM: Studies of the descriptions of pain by children have neglected their linguistic development, therefore estimates of dental pain in children may not be accurate. This study sought (1) to identify words chosen by children to describe dental pain and (2) to establish the effect of linguistic development on that description. SAMPLE: Seventy-eight consecutive children between the ages of 5 and 13 years attending a paediatric dental clinic. METHOD: Each child completed the WORD reading comprehension test. They then underwent a pulp test and a simulated pulp test, administered by a dentist in a counterbalanced order, of a healthy primary canine or permanent incisor, according to the child's age. To describe each test, the children had to (1) select words from a list of 58 read by the experimenter and (2) give ratings on scales representing 'sore' and 'tingly'. RESULTS: Analysis of variance confirmed that the children chose more words for the pulp test than for the simulated test (P < 0.001); the former also elicited higher ratings for 'sore' and 'tingly'. The numbers of words chosen were transformed by a square root constant to ensure a normal distribution. Multiple regression analysis then showed that (1) the better the children's reading comprehension, the fewer words they chose, possibly because they were less inclined to choose unfamiliar words, and (2) the older they were, the more words they chose, possibly because of having more experience of pain. There were similar findings for ratings of 'sore' and 'tingly'. CONCLUSIONS: To assess children's experience of pain (1) they need to be presented with a list of words like the ones in this study, (2) the numbers of words chosen by them would represent the severity of pain, and (3) those numbers need to be adjusted for the children's reading comprehension and age.
