[Pain in pediatric dentistry: etiology and management].

From January 1998 to January 1999, 458 files of 2 to 15 years old patients have been collected to indexthe different causes of pain in pediatric dentistry and to record the treatments applied to face that. It arises from this study that BAUME category II takes up from as far to the first place (77.7 %) followed by the category III (2.3) with a notable difference which nevertheless, can be explained by the transient nature of this category in the child. However, according to our study, pain abolition doesn't exclusively depend on drugs, some surgical procedures are indispensable. At the end of this study, it is to retain that, in spite of the importance typically dental pain, the problem of pain in pediatric dentistry must be approached in a entire sight.

Mechanisms associated with unusual orofacial pain.

This article presents an overview of possible mechanisms associated with pain perception, with a specific focus on understanding unusual manifestations of orofacial pain associated with nerve insult. It includes recent evidence concerning neurobiological changes that occur in the periphery at tissue and nerve sites, or within the central nervous system, and that may involve chemical and inflammatory responses, sensitization, or alterations of cellular function. Moreover, the contribution of the autonomic nervous system, changes in emotional reactivity and vigilance, the roles of high brain centers such as the basal ganglia (nigro-striatal) system, and the influence of aging and gender, are briefly described.

Dental perspectives on neuropathic origin.

The most common cause of intraoral pain is odontogenic and rarely presents a diagnostic challenge. Pain in a tooth site area that is not dental or periodontal in origin may be difficult to diagnose and treat. Successful management of non-odontogenic pain complaints is inherently dependent on taking a detailed 'pain history'. Treatments that are irreversible and potentially harmful to the underlying dentoalveolar structures must be avoided when the diagnosis is uncertain. Information gleaned from the pain history usually provides a provisional or working diagnosis, and this diagnosis must later be confirmed by specific testing (based on response to medication trials, imaging, laboratory tests, etc.). Patients who suffer from chronic pain conditions are likely to show comorbidity with other pain problems (e.g., neuropathic pain with background muscle discomfort or temporomandibular disorders and headache problems). Thus, in more complex patients, the various elements that comprise the chronic pain condition must be identified and managed, for adequate resolution of the symptoms.

Endodontic flare-ups: comparison of incidence between single and multiple visits procedures in patients attending a Nigerian teaching hospital.

The present study was performed to compare the incidence of endodontic flare ups in single with multiple visits treatment procedures, to establish the relationship between pre-operative and post obturation pain in patients attending for endodontic therapy in a Nigerian teaching Hospital. Patients were randomly assigned to either single visit or multiple visits group. Data collected at root canal treatment appointment and recall visits (1st, 7th and 30th day post obturation) include pulp vitality status, the presence or absence of pre-operative pain, presence and degree of post obturation pain. Presence of endodontic flare-ups (defined as either patient's report of pain not controlled with over the counter medication and or increasing swelling). The compiled data were analyzed using chi-square where applicable. P level < 0.05 was taken as significant. Ten endodontic flare-ups (8.1 %) were recorded in the multiple visits group compared to 19 (18,3%) flare-ups for the single visit group, P = 0.02. For both single and multiple visits procedures, there were statistically significant correlations between pre operative and post obturation pain (P = 0.002 and P = 0.0004 respectively). Teeth with vital pulps reported the lowest frequency of post obturation pain (48.8%), while those with non vital pulps were found to have the highest frequency oh post obturation pain (50,3%), P = 0.9. Although the present study reported higher incidences for post obturation pain and flare-ups following the single visit procedures, single visit endodontic therapy has been shown to be a safe and effective alternative to multiple visits treatment.

An evaluation of self-reported oral health and health-related quality of life.

The purpose of this study was to investigate the general and oral health status of patients at a dental hospital in Tokyo and examine the correlations between general health and oral health items. One hundred and seventy-four (174) new patients at the Dental Hospital of Tokyo Medical and Dental University participated in this study. The Visual Analog Scale (VAS) was employed to investigate dental demands and symptoms, as well as satisfaction with oral and general health conditions, while SF-36 served an indicator for health-related quality of life (HRQOL). The results were statistically analyzed at a significance level of p = 0.05. The results of VAS were further examined using factor analysis. Several VAS items showed significant correlations with SF-36 subscales (p<0.05). The factor analysis of VAS items suggested a structure involving three factors: self-cognition of oral status, related function and pain, and dental fear and discomfort. The dental fear and discomfort factor showed no significant correlations with SF-36 subscales (p>0.05). Emotional elements and esthetic demands on dental status, as well as physical symptoms, influence HRQOL. Dental discomfort proved to be independent of general health status and was considered a dental-specific item that needs to be measured separately from general health status.

[Oral health care practices in Abidjan].

Abidjan, the economical capital of Ivory Coast has a CAO of 2.7 with index O practically nil. The professional density is one surgeon for 12.000 inhabitants. Abidjan population, despite the requirements in increasing care has not recourse to the dental surgeons for their assumption of responsibility. The general objective of our study is to describe the therapeutic itinerary in odonto-stomatology of the Abidjan population. We have realised a questionnaire survey beside of population sample. The results show that 25 per cent of our population gives up care despite the presence of pain or embarrassment. Our study has allowed highlighting all the other recourses to the care. Indeed, the people who give up the care have much other recourse which has be identified in order of importance: the modern and traditional self-medication. Let us note in our study, that the choice of dental surgeon knows a constant evolution from the first to the third recourse. The lack of financial means constitutes however the first obstacle at the accessibility to the oral care in Ivory Coast.

Blink reflexes in patients with atypical odontalgia.

AIMS: To use the human blink reflex (BR) to explore possible neuropathic pain mechanisms in patients with atypical odontalgia (AO). METHODS: In 13 AO patients, the BR was elicited using a concentric electrode and recorded bilaterally with surface electromyographic (EMG) electrodes on both orbicularis oculi muscles. Electrical stimuli were applied to the skin above branches of the V1, V2, and V3 nerves and to the V branch contralateral to the painful branch. Sensory and pain thresholds were determined. The BR examination of the painful V branch was repeated during a capsaicin pain-provocation test. The data were analyzed with nonparametric statistics. RESULTS: The BR responses (R2 and R3) evoked by stimulation of V3 were significantly smaller than the BR responses evoked by stimulation of V1 and V2 (P < .004). There were no differences in BR (R2 or R3) between the painful and nonpainful sides (P > .569), and the BR (R2 and R3) was not significantly modulated by experimental pain (P > .080). The sensory thresholds were significantly lower on the painful side compared to the nonpainful side (P = .014). The pain thresholds were not different between sides (P > .910). CONCLUSION: No major differences between the V nociceptive pathways on the right and left sides were found in a relatively small group of AO patients. Future studies that compare BRs in AO patients and healthy volunteers are needed to provide further knowledge on the pain mechanisms in AO.

Vanilloid receptor 1 expression in human tooth pulp in relation to caries and pain.

AIMS: To investigate the presence of vanilloid receptor 1 (TRPV1) in human dental pulp and to correlate any expression with caries and pain. METHODS: Permanent mandibular first molars were collected and categorized as intact or grossly carious. Grossly carious teeth were further categorized as carious asymptomatic or carious painful samples. Coronal pulps were removed and processed for indirect immunofluorescence using antibodies raised against TRPV1 and a neuronal marker, either protein gene product 9.5 or alpha-smooth muscle actin, in conjunction with Ulex europaeus agglutinin 1 lectin to fully label the pulp vasculature. RESULTS: Analysis revealed that TRPV1 labeling was not confined to pulpal nerve fibers. TRPV1 was also consistently expressed within pulp microvasculature. Expression of neuronal TRPV1 was significantly increased throughout the pulp in grossly carious samples (P < .05). No significant differences were found between carious asymptomatic and carious painful samples. A significant increase in vascular TRPV1 expression was observed in arterioles present in the midcoronal pulp in carious painful compared with carious asymptomatic samples (mean area +/- SEM [%] of TRPV1 to vascular labeling; 6.48% +/- 4.5% for carious asymptomatic teeth, n = 9; 31.21% +/- 9.6% for carious painful teeth, n = 9; P = .02). CONCLUSION: Expression of TRPV1 in pulpal nerve fibers undergoes marked changes with caries. This may be of relevance in the development of pulpal inflammation, but its relationship to dental pain is still unclear. However, vascular TRPV1 expression does appear to be positively correlated with dental pain, thus providing new insights into symptomatic pulpitis.

Prescription opioid abuse: dental perspectives.

Drug abuse and diversion of controlled substances prescribed by dentists will continue to be an important issue in the overall management of dental pain, and must be recognized by the dentist. If suggested guidelines, regulations, and laws are observed, the associated problems for the dentist and the entire dental team and their patients can be minimized. Pain control is an essential service and duty for dentists, and the appropriate selection and use of analgesics affords this service with the best safety and efficacy.

Reasons for early loss of primary molars.

PURPOSE: The aims of this study were to investigate the principal reasons for untimely loss of primary molars and to evaluate the risk factors of early primary molar loss in children aged four to nine years. MATERIALS AND METHODS: 1150 untimely lost primary molars were analyzed from 546 patients. The early loss of primary molars was analyzed in relation to age, sex, dmf (t), DMF (T) scores, toothbrushing frequency, history of treatment and maternal education. The data were converted to SPSS format. Pearson Chi-square test was used for statistical analysis. RESULTS: Among the investigated subjects, 15.2% of children reported regular toothbrushing. Only 23.1% of subjects had a history of treatment before the tooth extraction and 33% of mothers had a low education level. Untimely loss of primary molars due to pain, caries and sepsis were 30.2%, 31% and 38.8%, respectively. The frequency of 'only one primary molar loss' was significantly higher in group 1 (p < 0.05), however the frequency of 'more than one primary molar loss' for group 2 was more than group 1 (p < 0.05). Irregular toothbrushing for the children in group 2 was found significantly high than in group 1 (p < 0.05). Irregular toothbrushing was associated with number of early primary molar loss in group 2 (p < 0.05). The level of maternal education was associated with dmf (t) scores (p < 0.05). The caries incidence was associated with number of early primary molar loss in both groups (p < 0.05). The mean number of treated teeth before extraction for group 2 was significantly higher than for group 1 (p < 0.05). CONCLUSION: Results of this study suggested that irregular toothbrushing, high dmf (t) scores and untreatment of carious primary molars were significant risk factors in early loss of primary molars. Every effort must be taken into account in restoring rather than extracting carious teeth.

Nonsteroidal anti-inflammatory drugs: confusion, controversy and dental implications.

Nonsteroidal anti-inflammatory drugs (NSAIDs) have been used in the treatment of pain, including pain of dental origin, for many years. Even though they are effective in relieving symptoms, they are not without adverse events, most notably upper gastrointestinal toxicity. To prevent this side effect, the pharmaceutical industry developed NSAIDs that selectively inhibit the cyclooxygenase 2 (COX-2) isoenzyme, which is inducible and expressed at sites of inflammation, while sparing the COX-1 isoenzyme, which is associated with gastric protection. On September 30, 2004, the company that produced rofecoxib (Vioxx), a COX-2 inhibitor, voluntarily withdrew this product from the market based on the discovery of its association with increased risk of adverse cardiovascular events reported in an ongoing large clinical trial. This unexpected event caused the medical community to review existing literature regarding this and related medications and also led to the emergence of novel research to improve understanding of the potential mechanisms for this serious side effect. However, instead of clarifying the situation, reports created confusion and controversy regarding the safety of all types of NSAIDs. The major concern is an increase in adverse cardiovascular events with the use of individual drugs as well as the potential for a class effect. In this article, we review recent events and findings and discuss the implications for dentistry.

[Effects of the method of mechanical root canal treatment on emergence of pain after endodontic management].

For assessment of tooth canal mechanical preparation method influence upon frequency of pain emergence after endodontic treatment, laboratory and clinical evaluation of sound tools of the Sonic system, ultrasound tools of the Satelec Suprasson system, full-wind tools of Pro Taper and System GT as well as handy K-files was performed. It was found that the least risk of pain emergence after endodontic treatment occurs with tooth canal widening by CrownDown technique because in this case the minimal amount of canal preparation products are educted into periodontal tissues.
