From September 1981 to February 1982, an epidemiologic study was carried out on the incidence of pain conditions among patients between 18 and 70 yr of age in 30 dental practices in Ribe County, Denmark. A total of 35 464 patients consulted the 50 participating dentists during the study period. 823 patients consulted the dentist due to pain. The most frequent cause of pain was caries sequelae (pulpitis (35%) and acute apical periodontitis (31%)). There was a significant difference in the distribution of the diagnoses between patients with regular and non-regular dental care. Although the data in the present study may not be representative for the entire Danish population, it seems reasonable to assume that in Denmark there are at least 70 000 annual consultations to a dentist due to pain. Furthermore, a minimum of 4000 patients can be expected to be absent from work annually, due to illness caused by dental pain.

This study aimed to assess oral health status and the social impact of oral conditions among dental patients with HIV infection in comparison with general dental patients receiving public-funded care in Adelaide, South Australia. DMFT and CPITN indices were recorded by one dentist at a clinic for HIV dental patients. The data were compared with information from an existing survey of general dental patients. Social impact was assessed using the Oral Health Impact Profile questionnaire and responses from HIV dental patients were compared with responses from a telephone interview survey of Adelaide residents. HIV patients were aged 21 to 49 years (median = 34), 90.7 percent were male and 29.6 percent had stage 4 HIV infection. Oral candida was present among 32.0 percent, hairy leukoplakia among 24.1 percent, HIV gingivitis among 18.5 percent, and HIV periodontitis among 33.3 percent. The DMFT index and its components did not differ significantly between HIV and general dental patients, while CPITN scores were lower among HIV patients (p = 0.01). However social impact among HIV patients was frequent: 64.6 percent reported toothache, 43.7 percent avoided foods, and 16.7 percent avoided going out because of dental problems. HIV patients reported significantly greater levels of social impact than the Adelaide sample (p < 0.01). Patients to this clinic frequently presented with severe and disabling oral conditions which were not adequately captured using standard clinical indices.

In 1992 a questionnaire was sent to 50-year-olds in two Swedish counties. These self-report data were compared with clinical observations with regard to number of teeth, removable dentures, caries, and periodontitis. Complete information from both data sources was obtained for 1041 persons. The relevant questionnaire item explained 71% of the missing tooth variance. An agreement of 0.91 (Cohen's kappa) was obtained for removable dentures. A question about problems in opening the mouth differentiated clearly with regard to measured mouth opening ability. Toothache and tooth sensitivity were reported with 95% probability when having 22 decayed teeth and with 46% when there were no decayed teeth (58% correctly predicted). Two teeth with pockets > or = 6 mm gave 5% probability and 22 such teeth gave 39% probability of reporting migration of front teeth. The main conclusion from this study is that there is good correspondence between subjective self-reports and clinical findings, especially for those conditions that are relatively easy for the patient to observe, such as the number of teeth and the presence of dentures. Thus questionnaire data can be used for information and screening about some well-defined oral conditions.

The present studies evaluated the efficacy of a controlled-release biodegradable chlorhexidine (CHX) (2.5 mg) chip when used as an adjunct to scaling and root planing on reducing probing depth (PD) and improving clinical attachment level (CAL) in adult periodontitis. Two double-blind, randomized, placebo-controlled multi-center clinical trials (5 centers each) were conducted; pooled data are reported from all 10 centers (447 patients). At baseline, following 1 hour of scaling and root planing (SRP) in patients free of supragingival calculus, the chip was placed in target sites with PD 5 to 8 mm which bled on probing. Chip placement was repeated at 3 and/or 6 months if PD remained > or = 5 mm. Study sites in active chip subjects received either CHX chip plus SRP or SRP alone (to maintain study blind). Sites in placebo chip subjects received either placebo chip plus SRP or SRP alone. Examinations were performed at baseline; 7 days; 6 weeks; and 3, 6, and 9 months. At 9 months significant reductions from baseline favoring the chlorhexidine chip compared with both control treatments were observed with respect to PD (chlorhexidine chip plus SRP, 0.95 +/- 0.05 mm; SRP alone, 0.65 +/- 0.05 mm, P < 0.001; placebo chip plus SRP, 0.69 +/- 0.05 mm, P < 0.001) and CAL (chlorhexidine chip plus SRP, 0.75 +/- 0.06 mm; SRP alone, 0.58 +/- 0.06 mm, P < 0.05; placebo chip plus SRP, 0.55 +/- 0.06 mm, P < 0.05). The proportion of patients who evidenced a PD reduction from baseline of 2 mm or more at 9 months was significantly greater in the chlorhexidine chip group (19%) compared with SRP controls (8%) (P < 0.05). Adverse effects were minor and transient toothache, including pain, tenderness, aching, throbbing, soreness, discomfort, or sensitivity was the only adverse effect that was higher in the chlorhexidine group as compared to placebo (P = 0.042). These data demonstrate that the adjunctive use of the chlorhexidine chip results in a significant reduction of PD when compared with both SRP alone or the adjunctive use of a placebo chip. These multi-center randomized control trials suggest that the chlorhexidine chip is a safe and effective adjunctive chemotherapy for the treatment of adult periodontitis.

The concept of a tooth-worm, which according to popular belief, caused caries and periodontitis, has existed in diverse cultures and across the ages. During the Enlightenment, however, the theory of the tooth-worm was assigned by medical doctors almost exclusively to superstition. Even so, the idea that toothache was caused by gnawing worms held on even into this century. There were many different ideas with regard to the appearance of tooth-worms. In England, for instance, it was thought that the tooth-worm looked like an eel. In Northern Germany, people supposed the tooth-worm to be red, blue, and gray and in many cases the worm was compared to a maggot. The gnawing worm was held responsible for many evils and, in particular, was blamed for toothache provoked by caries. The question is discussed of how the belief in the existence of the tooth-worm in former times can be explained. In popular medicine, numerous therapies were applied in order to eradicate the tooth-worm. In addition to the fumigations with henbane seeds, which allowed the "tooth-worm" to develop in the form of burst seeds, there were also magical formulas and oaths.

The present study explored whether immersive virtual reality can serve as an effective non-pharmacologic analgesic for dental pain. Two patients (aged 51 and 56 years old) with adult periodontitis, a chronic, progressive inflammatory disease that affects gums, ligaments, and bones around the teeth, were studied in the treatment room of a periodontist. Each patient received periodontal scaling and root planing (scraping off/removing plaque deposits below the gum line, hereafter referred to as scaling) under three treatment conditions: (1) virtual reality distraction, (2) movie distraction, and (3) a no-distraction control condition. Condition order was randomized and counterbalanced. For each of the three treatment conditions, five visual analog pain scores for each treatment condition served as the dependent variables. On 0-10 labeled scales, both patients provided sensory and affective pain ratings, and subjective estimates of time spent thinking about his pain during the procedure. For patient 1, mean pain ratings were in the severe range while watching a movie (7.2), or no distraction (7.2) but in the mild pain range (1.2) during the VR condition. Patient 2 reported mild to moderate pain with no distraction (mean = 4.4), mild pain while watching the movie (3.3), and essentially no pain while in VR (0.6) during his periodontal scaling. Although the small sample size limits generalizability, we contend that virtual reality is a uniquely attention-grabbing medium capable of maximizing the amount of attention drawn away from the "real world," allowing patients to tolerate painful dental procedures. These preliminary results suggest that immersive VR merits more attention as a potentially viable adjunctive nonpharmacologic analgesia for procedural dental/periodontal pain. Virtual reality may also have analgesic potential for other painful procedures or pain populations. Practical implications are discussed.

We report two cases of septic pulmonary embolism associated with periodontitis. Chest CT revealed multiple nodular shadows with features characteristic of septic pulmonary embolism in both patients. Both patients had toothache, fever, and chest pain, and showed findings of periodontitis at initial presentation. Antimicrobial agents combined with dental surgery were successful in treatment. While septic pulmonary embolism from the lesions of periodontitis appears to be rare, periodontitis remains important in the differential diagnosis of septic pulmonary embolism.

Dental pain, estimated to affect 12-40% of community-dwelling adults, is a symptom of a wide range of clinical conditions. A population screening instrument is needed to study their prevalence. This project aimed to develop a questionnaire for classifying a sample of dental pain patients into three groups of common dental pain conditions, i.e. Group 1 (Acute periapical periodontitis and Irreversible pulpitis), Group 2 (Reversible pulpitis and Dentine hypersensitivity) and Group 3 (Pericoronitis). Initial items were generated through a literature review, individual unstructured patient interviews and consultation with experts. Items generated were administered to a sample of dental pain patients for self-completion. Responses were subjected to a series of factor and discriminant analyses to identify questions capable of differentiating the sample into three groups, originally categorized by clinical diagnosis, with high classification rates. The selected items were administered to a further sample of dental pain patients to test for its sensitivity and specificity in classifying the sample into three groups against the gold standard of clinical diagnosis. The final 16-item Dental Pain Questionnaire (DePaQ) was capable of correctly classifying 89.7% of dental pain cases initially categorized by clinical diagnoses. The sensitivity of the questionnaire was 0.80-Group z1, 0.85-Group 2 and 0.59-Group 3. Specificity was 0.83-Group A1, 0.89-Group A2 and 0.90-Group 3. The DePaQ, which can easily be administered by non-clinical personnel, may be used to collect epidemiological data on common dental pain conditions, assess dental needs for a specified population, and triage of patients seeking treatment for dental pain.

Toothache can be prevented or remedied with a root canal treatment. Unfortunately a root canal treatment can also be the cause of pain. During a root canal treatment pain can be suppressed by local anesthesia, the use of the airotor, the attitude of the dentist and his communication with the patient. Afterpain has three causes: damage and iatrogenic apical periodontitis, pulpitis and continuing apical periodontitis. In this article the possible treatment of pain by a root canal treatment are extensively discussed.

An essential feature of symptomatic periradicular inflammation is mechanical allodynia, defined as reduced mechanical pain thresholds. A previous study evaluating a new digital force transducer showed that it reliably measures mechanical pain thresholds of teeth with normal periradicular tissues. In this study, we tested the hypothesis that the force transducer quantitatively measures mechanical allodynia in teeth with acute periradicular periodontitis (APP) and detects the effects of local anesthetic injection. Mechanical pain thresholds were measured in patients (n = 30) with irreversible pulpitis (IP) and APP and compared with their contralateral teeth. The results show that the mechanical pain thresholds of teeth with IP and APP were reduced by 77% compared with contralateral control teeth. The administration of local anesthesia reversed the mechanical allodynia by 62%, and significant sex-specific effects were observed. In addition, the normal teeth contralateral to the symptomatic teeth had lower mechanical thresholds than those observed in healthy volunteers, suggesting that central sensitization occurs during this type of odontalgia. Thus, we show that the mechanical pain thresholds are significantly reduced in teeth with IP and APP and that the force transducer has potential application as a diagnostic aid in measuring mechanical allodynia and as an outcome measure in endodontic clinical trials such as pharmacologic studies and mechanistic research.
