The role of Dental Fear, Pain anticipation and Self-efficacy in Endodontic Therapy.

BACKGROUND: Cognitive-behavioural interventions may be important for the prevention and treatment of oral diseases. One cognitive factor that has generated considerable interest as a possible mediator is self-efficacy. METHODS: One hundred patients diagnosed with pulpal or periapical pathology that required endodontic therapy were treated. Data were collected at baseline in the waiting room before therapy and then during treatment. RESULTS: Positive correlations were found between dental fear, pain anticipation and dental avoidance (p⟨0.001). The correlation between dental fear and pain anticipation showed the largest effect sizes. Healthy participants had higher scores in self-efficacy (Mean=32.55; SD=7.15) than those with systemic diseases (n=15; Mean=29.33; SD=4.76, p=0.04). Participants who not taking medication before treatment had lower scores for pain anticipation (Mean=3.63; SD=2.85) than those taking medication. The contribution of pain anticipation to dental avoidance varied at different values of self-efficacy. The indirect effect of dental fear on dental avoidance via dental anxiety was significant in individuals with higher self-efficacy. CONCLUSIONS: Self-efficacy had an essential moderation role between pain anticipation and dental avoidance during endodontic treatment.

SECOND LATIN AMERICAN INTERCOMPARISON ON INTERNAL DOSE ASSESSMENT.

Internal dosimetry intercomparisons are essential for the verification of applied models and the consistency of results'. To that aim, the First Regional Intercomparison was organised in 2005, and that results led to the Second Regional Intercomparison Exercise in 2013, which was organised in the frame of the RLA 9/066 and coordinated by Autoridad Regulatoria Nuclear of Argentina. Four simulated cases covering intakes of (131)I, (137)Cs and Tritium were proposed. Ninteen centres from thirteen different countries participated in this exercise. This paper analyses the participants' results in this second exercise in order to test their skills and acquired knowledge, particularly in the application of the IDEAS Guidelines. It is important to highlight the increased number of countries that participated in this exercise compared with the first one and, furthermore, the improvement in the overall performance. The impact of the International Atomic Energy Agency (IAEA) Projects since 2003 has led to a significant enhancement of internal dosimetry capabilities that strengthen the radiation protection of workers.

The impact of dental appearance and anxiety on self-esteem in adult orthodontic patients.

OBJECTIVES: To analyse the relationship between different dimensions of dental appearance impact and self-esteem in adult patients undergoing orthodontic treatment, with special attention to the possible mediating role of anxiety. SETTING AND SAMPLE POPULATION: A quasi-experimental design was used with a matched control group (without orthodontic treatment). In each group (experimental and control), there were 85 patients. MATERIAL AND METHODS: The impact of dental appearance was measured using the Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ). State anxiety was assessed with the State Anxiety Inventory (STAI-S) and self-esteem with Rosenberg's self-esteem scale. RESULTS: In both groups (experimental and control), self-esteem correlates negatively, ranging between 0.26 and 0.43, with all dimensions of dental appearance impact (except for the positive dental self-confidence dimension, where all correlations were positive). Anxiety correlates positively, ranges between 0.35 and 0.44, with social impact, psychological impact and aesthetic concern, although it maintains no significant correlations with dental self-confidence. Nevertheless, in patients undergoing orthodontic treatment, anxiety plays a mediating role between dental impact dimensions and self-esteem, whilst for the control group anxiety only plays a mediator role between psychological impact and self-esteem. CONCLUSION: Anxiety plays a fundamental role in the effect of perceived dental impact on self-esteem in adult patients undergoing orthodontic treatment. These results have important practical implications for the design of bio-psycho-social intervention programs that contemplate cognitive-affective variables as an essential part of orthodontic treatment in adults.
