[Analysis of the circadian rhythm of pain].

An electronic pulp tester was used to study the stimulus threshold in human teeth of 28 healthy volunteers for 1,5-4 days and the duration of local anaesthesia in 55 patients with caries. Rhythm analysis was performed with a non-linear fitting program on an IBM computer (PHARMFIT); in 21 out of the 28 volunteers significant daily rhythms in stimulus threshold could be detected. In the patients the maximum duration of local anaesthesia was after drug application at 2 p.m.

[Dentistry and its remedies in the Netherlands during the 17th century].

The XVIIth century is the Golden Century of Holland, liberated from spanish domination, and becoming an economical and political powerful State, owing to maritime trade. Art, Science and literature progress and shine as never equaled. Our investigation is based upon writtings of professors, and those of their students or any other practitioner newly established in Holland, land of liberty. In those writings we are in search of remedies against odontology. Usual therapeutics is all together general and local. General, its evacuated peccant humors by vein section and purgation; local, it acts upon surrounding regions (shoulder, tempel, ear, chin), in the mouth (collutorium), on the tooth or its cavity.

[Study of pain sensitivity based on the indicators of electro- odontometry in patients with depersonalization and depressive disorders].

Electroodontometry was used to examine the pain threshold and sensation threshold in patients with depersonalization, endogenous depression and in mentally healthy test subjects. The strongest differences in the thresholds were found on the anterior teeth. The patients with depersonalization manifested a considerable rise of the sensation threshold and to an ever greater degree of the pain threshold. In patients suffering from endogenous depression, both thresholds were decreased and coincided almost completely. It is likely that this fact is associated with a relatively higher incidence of the painful syndrome in patients suffering from depression.

Chronic orofacial pain. A practical approach to differential diagnosis.

Successful diagnosis of chronic orofacial pain is a difficult task. This article attempted to simplify diagnosis by first classifying the orofacial pain on the basis of clinical characteristics into three basic pain categories: somatic, neurogenous, and psychogenic, and then according to the tissue system affected. An accurate and thorough history is essential, along with a detailed physical examination. In addition, an awareness of the local, systemic, and psychological causes of orofacial pain is necessary. The adage "what you don't know, you don't diagnose" is especially apt in regard to orofacial pain.

"The clam syndrome". Dental pain of unusual etiology.

Odontogenic pain may be due to periodontic or endodontic etiology. Myofacial and temporomandibular joint pain as well as sinusitis may cause referred pain to teeth. The following cases demonstrate yet another source of referred pain that could potentially cause a misdiagnosis.

[Self-medication with analgesics. A study on odontalgia].

BACKGROUND: Odontalgia is a painful condition which is frequently associated to self-medication with analgesics. The purpose of the present study was to evaluate the main characteristics of self-medication on these patients. METHODS: A total of 226 patients who requested medical care for odontalgic problems at ambulatory level were evaluated. A case from was completed for each patient, considering diagnostic syndrome, pain characteristics and self-medication. RESULTS: Pain was present in 59% of the patients with a mean duration of near 20 days. Its intensity was mainly from moderate to severe, but one third of the patients referred very severe or excruciating pain. Near seventy percent of all patients with pain complaints were self-medicating with analgesics, 55% of them with one drug, 36% with two and 8% with three. A clear trend to use more drugs when pain intensity was higher was observed. The most frequently used drugs were paracetamol (39%), acetilsalicylic acid (24%) and metamizol (17%). The majority of patients selected themselves the drug and only a small number were advised by pharmacist or non health professionals. CONCLUSIONS: The present study shows a high frequency of self-medication in patients with odontalgia suggesting that this type of pain might be useful as a model to study self-medication with analgesic drugs.

[Pulp response to restorative materials].

Restorations may affect the pulp negatively, rather due to microleakage than to toxic properties of the materials used. Hyperalgesia occurs more frequently after restoration with composite resins than with amalgam, though the resins in contrast to amalgam may be bonded to the enamel margins. A number of recommendations are presented in order to minimize the marginal gap between cavity walls and amalgam and to prevent marginal fracture.

Acute dental pain, Part 1: Diagnosis and emergency treatment.

The diagnosis and emergency treatment of acute dental pain that arises from periodontal or pulpal involvement are presented. Part I of this two-part series investigates periodontal-related emergencies that manifest as abscesses, cysts, and necrotizing ulcerative gingivitis (NUG). An attempt is made to clarify the differences among these emergencies by presenting their commonly associated symptoms and suggesting a logical approach to diagnosis and treatment.

Acute dental pain, Part II: Diagnosis and emergency treatment.

Part II of this two-part series differentiates and explores endodontic-related emergencies with reversible and irreversible pulpitis. Indications and contra-indications for vital pulp therapy are explained, and treatment is outlined. The inflammatory process involved in irreversible pulpal disease is summarized, and the clinical signs, symptoms, and treatment of irreversible pulpitis (with and without acute periradicular involvement, with pulp necrosis, and acute periradicular abscess with and without cellulitis) are discussed.

Betel chewing and dental decay.

A survey was carried out on Four hundred and sixty patients to find out the effects of betel chewing on dental caries & oral hygiene. It was found that among the betel chewers as well as the non betels chewers., the highest caries susceptibility was in the age group of 20-34 years. Also caries susceptibility was higher among the females as compared to males. It was also observed that though the habit of betel chewing reduces the incidence of dental decay, maintenance of oral hygiene is very poor.

[Use of soft laser in the treatment of oral symptoms].

Due to insufficient casual therapy of oral symptoms of dyniae and pyrosis, we applied infrared soft laser in treatment of patients with those oral symptoms. The laser had a wavelength of 904 nm and a radiation strength of 20 W. The tests were performed on 40 persons with stomatopyrosis and stomatodiniae symptoms, under application of laser through 5 days consecutively with radiation of mucosa lasting 3 minutes on 1 cm2. The testing group was represented by persons exclusively under the laser therapy and the control group was represented by 30 persons, who were under a medicamentose therapy with vasodilatator applied with iontophoresis. By persons with stomatopyrosis and stomatodiniae symptoms analgetic effect was attained through the therapy with the laser already after the first application, and the pain and aches intensity was relieved every day during the therapy, by stomatodinae to complete healing. The obtained differences in the intensity of symptoms before and after the therapy were statistically important. The thermoestesiometric determination of laser efficiency by vasodilatation showed differences which were not important, although the temperature during the therapy has slightly increased for 0.1 degrees C. The soft laser can be used as an effective remedy in the treatment of oral symptoms of stomatopyrosis and stomatodinae.

[Laterality of the facial MT change as the response to oral stimuli including oral sensation or dental pain].

Minor Tremor (MT), spontaneous about 10 Hz oscillation on the body surface, can be an effector index of physiological reflex behaviors. Many investigations have been made from the thumb balloon surface. Few investigations have been made from the facial surface. No investigation has been made on the laterality of the facial MT. This investigation has been focused on the last problem. The reflex arc has been supposed in order to understand the change of MT described here; the afferent signal is discomfort oral afferent, the efferent route is neuromuscular oscillative system for MT, and the reflex centre is emotional system. When oral discomfort afferents are increased, histogram pattern of facial MT is changed. Control pattern of MT is characterized by unimodal pattern. This pattern changes in parallel to the change in afferent signalling. The side that these MT changes occur is taken with reference to the side that the oral afferents originate. The side relation is also discussed.
