Colour Changes of Acetal Resins (CAD-CAM) In Vivo
To quantify the discolouration of the temporary acetal resins in vivo, based on the weeks
of follow-up and the salivary pH in the three thirds of the tooth. To find out if the final CIELAB
coordinates can be predicted from the initial colour coordinates, the salivary pH, the situation (in
thirds) and the weeks of follow-up. Colour coordinates (L, C, and h) were recorded by spectrophotometry
in 13 participants fitted with hybrid provisional complete dentures made of acetal resin.
Colour recordings were made on the day of placement and after several weeks of follow-up (6 to
31 weeks). Salivary pH was also measured as a predictor variable for colour change. The ANOVA
statistical test and regression models have been used. The highest colour difference according to
DEab* was 27.46 units after 15 weeks of follow-up and the lowest was 7.34 units after 17 weeks of
follow-up. Neither in the cervical nor in the middle third any regressor variable (initial L*, initial C*,
initial h*, salivary pH and weeks of follow-up) was able to significantly predict any of the final colour
coordinates (p > 0.05). The colour change of the temporary acetal resins used exceeds the threshold
of clinical acceptability, and it is not acceptable to maintain satisfactory aesthetics. The weeks of
follow-up and the salivary pH are not capable of satisfactorily predicting the final color coordinates
of the acetal resins
Adaptation and validation for Spain of the child-oral impact on daily performance (C-OIDP) for use with adolescents
Objectives. To linguistically and culturally adapt the Child-OIDP, an Oral Health-Related Quality of Life (OHRQoL) index, into Spanish for use among adolescents, and to validate it by evaluating the psychometric properties of the self-administered version. Study design. Following a forward - backward translation procedure, the English version of the questionnaire was translated by independent translators and the reconciled version was then sent to three experts for assessment. A pilot study was conducted on a sub-sample of 30 adolescents aged between 11 - 12 years to assess their understanding of the questionnaire and its wording. The participants in the main study comprised 425 school children aged from 11 to 14 and pertaining to the oral health survey on school children in Navarre; these children were given a clinical examination and answered a structured questionnaire on oral health self-perception, satisfaction and perceived dental treatment needs. We evaluated the content validity, face validity, criterion validity, internal consistency and reliability. Results. With regard to the face validity, the experts? opinion was that the version was adequate. The pilot study indicated minor changes to the wording to better adapt it for the target population. Regarding criterion and construct validity, the association of the C-OIDP with the self-perception variables gave statistically significant results (p<0.01) in all cases. For the internal consistency analysis, no negative correlations were present in the correlations matrix nor were any of the values too high to become redundant; the majority were statistically significant (p<0.05). Cronbach?s alpha value was 0.68, with corrected item-total values of between 0.20 and 0.56 and with no alpha if-item-deleted values greater than 0.68. The test-retest analysis gave an intraclass correlation coefficient (ICC)=0.98. Conclusion. The Spanish version of the self-administered questionnaire for the C-OIDP for adolescents adequately demonstrated successful psychometric properties and, therefore, is a valid and reliable instrument for measuring the OHRQoL of adolescents
Validation the Oral Health Impact Profile (OHIP-14sp) for adults in Spain
Objectives:
The oral health-related quality of life indicators are increasingly used to measure the impact of oral conditions on quality
of life to complement clinical data in cross-sectional and longitudinal studies. One of the most internationally spread indi-
cators is the Oral Health Impact Profile (OHIP-14), but it has still never been applied in Spain. The aim of this study was
to validate the OHIP-14 for use among adults in Spain.
Study design:
A cross-sectional study was performed in Granada (Spain). A consecutive sample (n=270) of the Regional Government staff
visiting the Employment Risk Prevention Centre for a routine medical check-up participated in this study. All participants
self-completed the piloted OHIP-14sp and were examined according to World Health Organization methodology for caries,
periodontal disease and prosthesis. Reliability analyses and validity tests were carried out to evaluate the psychometric
properties of the OHIP-14sp by using two different methods of total scoring (i.e. the Additive and the Simple Count).
Results:
The reliability coefficient (Cronbach Ìs alpha) of the OHIP-14sp was above the recommended 0.7 threshold and considered
excellent (alpha: 0.89). Some subjective factors (perceived dental treatment need, complaints about mouth and self-rated
oral satisfaction) were strongly associated with both total scoring methods of the OHIP-14sp, supporting the criterion,
construct and convergent validity. Moreover the impact levels were mainly influenced by caries data, e.g., number of teeth
requiring extraction (r = 0.21; p<0.01) and number of decayed visible teeth (between premolars) (r = 0.17; p<0.01). The
prevalence of impacts was 80.7% using the occasional or more frequently threshold. The most prevalently affected OHIP
domains were âpsychological discomfortâ (53.7%), âfunctional limitationâ (51.1%) and âphysical painâ (42.2%).
Conclusions:
The OHIP-14sp is a precise, valid and reliable instrument for assessing oral health-related quality of life among adult
population in Spain
Associated factors with health-compromising behaviors among patients treated for oral cancer
To improve eradication strategies of health-compromising behaviors between oral cancer survivors, this study aimed to explore the extent of clustering of risk behaviors and to assess possible factors associated. A cross-sectional study was carried out among oral cancer patients at least 6 months after treatment. They completed a questionnaire about smoking, alcohol consumption, oral hygiene habits and dental visits. Presence of clusters was evaluated through pairwise Pearson correlations and principal component analysis. Factors associated with each identified cluster were analyzed with multivariate models. Among 142 patients, 14.8% smoked, 51.7% consumed alcohol, 52.1% performed oral hygiene less than twice a day, and 74.6% visited to dentist when there was a problem or never. There were two distinct clusters: smoking-alcohol consumption (general risk behaviors cluster) and oral hygiene-dental attendance (oral risk behaviors cluster). Multivariate analysis showed significant associations between males and both clustering patterns of health compromising behaviors, patients with clinical stage I or with longer follow-up and the presence of general risk behaviors cluster and worse social class and the presence of oral risk behaviors cluster. A high proportion of patients treated for oral cancer presented health-compromising behaviors occurring in clusters which reinforce the need for health promotion strategies to target multiple behaviors. Factors analyzed suggest that chances of having detrimental behavioral clustering are higher in male, patients with clinical stage I, with lower social class and those with longer follow-up after treatment
Gender and Leadership Positions in Spanish Dentistry
The Research Ethics Committee of the University of Granada
issued a favorable report in relation to the present research under
number 2430/CEIH/2021.Data Availability
The data that support the findings of this study are available from
the corresponding author upon request.Dentists in Spain reached equal gender representation in 2012 and the number of female dentists has continued to grow
(until 57.3% in 2020). This study aims to increase evidence about the gender distribution on the high responsibility positions
and opinion leaders of the dental profession and academia. Composition of the executive comities of the main dental
institutions of Spain (regional professional associations, national dental association, and scientific societies), members of the
Faculty of Dentistry of the University of Granada in 2020 and speakers of the main dental congresses of 2019 (due to the lack
of congress in 2020) were recorded and analyzed by genders using chi-squared test (P < .05). Mean representation of female
dentists in executive committees of professional associations was 35.6%. More than 70% of presidents and vice-presidents
of professional colleges and more than 60% of these positions in scientific societies were occupied by male dentists. None of
dental congresses of 2019 reached equal gender participation, being 81.3% of lecturers presenting on main auditoriums male
dentists. Although dental workforce in Spain is slightly overrepresented by females, leadership positions and figures among
Spanish dentists doesnât seem to reflect the gender distribution of the collective. There is a lack of women occupying highlevel
positions in dentistry that proves the existence of the so-called âglass ceiling effectâ on the profession. Further studies
about sociodemographic aspects of dental workforce are needed to develop evidence-based policies for the collective.Research Projects of the Vice-rectorate of

Effect of Two Immediate Dentin Sealing Approaches on Bond Strength of Lavaâą CAD/CAM Indirect Restoration
The study was conducted according to the guidelines of the
Declaration of Helsinki, and approved by the Ethics Committee of the University of Granada (Spain)
(protocol code #1005/CEIH/2019 approved on 13 January 2020).Informed consent was obtained from all subjects involved in the studyThe objective of this work was to compare the micro-tensile bond strength (mu TBS) of CAD/CAM (Computer-Aided Design/ Computer-Aided Manufacturing) specimens cemented with different pairing of adhesives and resin-cements using two Immediate Dentin Dealing (IDS) approaches in comparison with Delay Dentin Sealing (DDS). Coronal dentin from 108 molars were divided into nine groups (n = 12) depending on the adhesive/resin-cement (A-C) assigned. Lava (TM) Ultimate (4 x 10 x 10 mm) was cemented according to different strategies: IDS1(cementation after dentin sealing), DDS (dentin sealing and cementation at 2-weeks), IDS2 (immediate dentin sealing and cementation at 2-weeks). Samples were sectioned and tested until failure to determine the mu TBS. Failure mode was categorized as dentin/cement (DC), at Lava (TM) Ultimate/cement (LC) and hybrid (H). Kruskal-Wallis and Mann-Whitney U tests and influence of the type of failure on the mu TBS by survival analysis with competing risk was explored. Mostly, mu TBS values were equal or higher in IDS2 than DDS. In general, A-Cs that showed higher mu TBS, have high percentages of LC failure. Survival analysis with competing risk between DC + H and LC values showed that some A-Cs would significantly increase the mu TBS values for IDS2. A-Cs with the highest adhesion values showed a high percentage of fractures at the LC interface, suggesting that the adhesion at the adhesive/dentin interface would be higher
