Exploring the opportunities and challenges to implementing interprofessional education in Saudi Arabia: a qualitative study among faculty.

Interprofessional education (IPE) has potential benefits for improving the quality of patient care, but its implementation is challenged with multiple barriers. The primary objectives of this study were to explore the challenges, benefits, and incentives to establishing IPE from the perspective of healthcare faculty at King Saud University. Forty-five faculty members attended six focus groups, each consisting of 6-8 faculty members representing the five colleges. The focus group interview guide included the benefits of and barriers to establishing IPE in this academic institution, curricular design, and the feasibility of support from the colleges and University administration. A SWOC (Strengths, Weaknesses, Opportunities, Challenges) frame work was utilized to guide the focus group discussions, and the data were analyzed inductively using thematic analysis. Three main themes emerged and were related to (i) barriers, (ii) benefits, (iii) opportunities to facilitate the introduction of IPE, and (iv) suggestions on how to implement IPE and overcome challenges to establish an IPE curriculum. Participants were generally supportive of IPE and aware of the constraints that might impede its implementation. Moreover, they identified potential barriers and incentives to promote IPE. Although participants appreciated the long-term benefits of IPE, creating a supportive environment will require the involvement of the academic community, including students, faculty members, and the University's top management.

Bonding integrity and compressive strength of re-bonded, surface conditioned and Er Cr YSGG laser treated lithium disilicate ceramics.

AIM: The aim of the study was to investigate the shear bond strength (SBS) and compressive strength (CS) of Er Cr YSGG laser (ECL) treated, re-bonded lithium disilicate (LD) ceramic in comparison to standard conventional conditioning (hydrofluoric acid (HFA) and silane). METHODS: One hundred LD ceramic disks were divided equally for SBS and CS testing. Eighty samples were conventionally surface treated and bonded to resin cement followed by de-bonding of the cement build-up. All de-bonded specimens were divided into four groups based on re-bonding surface treatments (HFA, primer, adhesive, and ECL). Resin cement build-ups were performed in 40 specimens for SBS testing (universal testing machine); however, the remaining 40 specimens were tested for CS. Ten specimens each were used as controls (surface treatment was performed once and no primary resin cement bonding) for SBS and CS assessment. Surface topography was assessed using a scanning electron microscope. RESULTS: The maximum and minimum SBS values were shown by groups: control (33.42 ± 3.28 megapascals (MPa)); and ECL (17.50 ± 2.22 MPa) respectively. The maximum and minimum CSs were displayed by specimens in the ECL group (439.45 ± 70.68 MPa) and the control group (237.28 ± 19.96 MPa), respectively. For ECL specimens, SBS was significantly lower and CS was significantly higher as compared to control specimens. CONCLUSIONS: Application of the Er Cr YSGG laser significantly improved the CS of de-bonded ceramic specimens. However, it did not show a positive influence on the bond integrity of re-bonded ceramics in comparison to conventional surface treatment regimes.

Knowledge and attitude towards dentist-industry relationship and their association with own behavior among dentists working in Saudi Arabia.

OBJECTIVES: To examine the knowledge and attitude towards dentist-industry relationship including accepting gifts, influence on decisions, and accuracy of given information among dentists working in Saudi Arabia. In addition, to examine the association of such knowledge and attitude of dentists' behavior with industry, including sorts of interaction and accepting industrial gifts. METHODS: A cross-sectional study was conducted among dental practitioners working in the private and governmental hospitals located in the various regions of Saudi Arabia. A self-administrated questionnaire was developed and distributed to all participants. Fourteen questions assessed the socio-demographic, economic, and occupational characteristics of the participants including age, gender, nationality, monthly revenue, income satisfaction, hospital setting, job rank, specialty, and patients' socio- economic status. Seventeen questions assessed the interaction with DSRs, acceptance and characteristics of gifts and opinion of dentists regarding gift acceptance in dental practice. One-Way ANOVA and t-test was used to examine differences in transformed scores by socio-demographic, occupations and outcome characteristics. All P-values were two-tailed. P-value < 0.05 was considered as significant. RESULTS: Total of 672 participants responded to general questions related to the knowledge and attitude. The mean of the overall knowledge and attitude score was 64.3 ±â€¯7.2, general questions score was 63.1 ±â€¯8.6 and interaction questions score was 66.9 ±â€¯8.0. Approximately, 40% of participants disagreed that accepting industrial gifts can affect their own decisions but slightly lower proportion (25%) disagreed that accepting industrial gifts can affect decisions of other dentists. Only 25% of participants thought it is ethical to accept industrial gifts and even fewer proportions (20%) believed that dental supply representatives (DSRs) always provide accurate information about their new materials. Almost two-thirds of participants trusted information from other sources than from DSRs. On the other hand, 40% of the participants were against banning industrial gifts to dentists and approximately 50% were against informing the patients about the industrial gifts given to their dentist by dental companies. CONCLUSIONS: There was insufficient knowledge and an overall positive attitude towards the dental industry among the sample of dentists in Saudi Arabia. Well-designed ethical education programs should be implemented to enhance knowledge and attitudes about the interactions with dental industry.

Effect of antimicrobial photodynamic therapy in open flap debridement in the treatment of peri-implantitis: A randomized controlled trial.

BACKGROUND: To evaluate the effects of single application of antimicrobial photodynamic therapy (aPDT) as an adjunct to open flap debridement (OFD) and OFD alone in patients with peri-implantitis (PI). MATERIALS AND METHODS: Twenty four patients with PI were divided into 2 groups receiving aPDT with OFD and OFD alone respectively. Peri-implant plaque index (PI), bleeding on probing (BOP), pocket depth (PD) and marginal bone level (MBL) were assessed at baseline, 6 and 12 months post-therapy. Digital periapical radiographs were taken and viewed on a calibrated computer screen using a software for the assessment of MBL. Only single implant from each patient was included in the study protocol (intent to treat analysis). RESULTS: At baseline, peri-implant PI, BOP, PD and MBL were comparable among individuals in aPDT and OFD groups. All patients had localized peri-implant PD ≥5 mm. At 6 months, aPDT and OFD significantly reduced peri-implant PI, BOP, PD and MBL. Similarly, after 12 months post-therapy, both groups reduced PI, BOP, PD and MBL. However, there was no significant difference between aPDT and OFD groups over time. CONCLUSION: Single application of aPDT as an adjunct to OFD does not provide additional benefit in improving clinical and radiographic peri-implant parameters in peri-implantitis.

Effect of photodynamic and laser therapy in the treatment of peri-implant mucositis: A systematic review.

BACKGROUND: The present study systematically reviewed the literature to investigate the effect of photodynamic therapy (PDT) or laser therapy (LT) in the management of peri-implant mucositis (p-iM). METHODS: The electronic databases were searched until October 2017. Outcome measures were bleeding on probing (BOP), plaque index (PI), or probing depth (PD). The addressed PICO question was: "Is PDT and LT effective in the management of p-iM?" RESULTS: A total of five studies included in the qualitative analysis, two of which had a low risk of bias. Three studies used PDT while two studies used LT. All studies reported a significant improvement in clinical peri-implant inflammatory parameters in p-iM. For PDT, one study demonstrated a significant reduction for PDT group as compared to manual debridement (MD), while one study indicated comparable outcomes when tested with probiotics at follow-up. One study used PDT alone and indicated significant improvements in peri-implant parameters at follow-up. However, in the studies using LT, one study demonstrated a significant improvement in peri-implant parameters as compared to scaling and root planing alone, while other study indicated comparable outcomes when compared with manual debridement/chlorhexidine group at follow-up. CONCLUSION: This systematic review demonstrated inconclusive findings to show the effect of PDT or LT in the management of p-iM due to methodological heterogeneity such as non-standard control groups, laser parameters and short follow-up period. The results of this review should be considered preliminary and further, more robust, well-designed studies with long-term follow up and standardized comparators with laser parameters are warranted.

Oral Health Status and Oral Health-related Quality of Life among Hospitalized and Nonhospitalized Geriatric Patients.

INTRODUCTION: The purpose of this study was to compare the oral health status and its effect on the oral health-related quality of life (OHRQoL) of hospitalized and nonhospitalized elderly patients in a single community. The null hypothesis for the study states that there is no difference in the oral health status and OHRQoL between hospitalized and nonhospitalized elderly patients. MATERIALS AND METHODS: This study was conducted at the King Khalid Hospital and College of Dentistry, King Saud University, Riyadh, Kingdom of Saudi Arabia. A total of 99 (43 - hospitalized and 56 - nonhospitalized) geriatric patients participated in this study. Oral health-related quality of life was estimated using the geriatric oral health assessment index questionnaire. Decayed, missing, and filled teeth (DMFT) index and plaque index were used to assess the oral health status of the study participants. RESULTS: The mean age of the study participants was 68.2 years; 17.2% were females and 82.8% were males. There was no significant difference between hospitalized and nonhospitalized patients in OHRQoL and DMFT index. However, the oral hygiene status was better among nonhospitalized patients as compared with hospitalized patients. CONCLUSION: There was a significant difference in the oral hygiene status between hospitalized and nonhospitalized geriatric patients. CLINICAL SIGNIFICANCE: Caregivers must be sensitized to the importance of oral health for the elderly population, and oral health should be considered an integral component of general health.

Accuracy of interchangeable implant impression systems: an in vitro pilot study.

PURPOSE: To evaluate the accuracy of impressions on changing the implant component (coping and abutment replica) between Brånemark and BIOMET 3i and between Straumann and Allfit. MATERIALS AND METHODS: Two master casts were constructed, one containing pair of Brånemark self-tap Mk II fixtures (Nobel Biocare) labeled Master cast I and the other containing pair of Straumann Standard plus implant, SLA fixtures (Straumann) labeled Master cast II. Ten impressions of each master cast were made by open tray technique using polyether impression material. Five out of 10 impressions made from master cast I contained Brånemark pair of coping and replica and the other 5 contained 3i (Implant Innovations). Five out of 10 impressions made from master cast II contained Straumann pair of copings and replica and the remaining 5 contained Allfit implants (Ihde Dental). Duplicated casts were prepared, and distances between copings were measured using traveling microscope and compared the distance in master casts. RESULT: No significant difference was observed in mean value between 2 master casts and their duplicates. CONCLUSION: The interchangeability of coping and abutment replica between Brånemark and BIOMET 3i and between Straumann and Allfit was found to be possible without compromising the quality of impressions.

The oral health-related quality of life in edentulous patients treated with conventional complete dentures.

OBJECTIVE: To compare the oral health-related quality of life (OHRQoL) between patients with both maxillary and mandibular complete denture and those with either the maxillary or the mandibular complete denture. BACKGROUND: Satisfaction of denture wearers can be estimated using the OHRQoL questionnaires like the OHIP-EDENT and the Geriatric Oral Health Assessment Index (GOHAI). METHODS: Two questionnaires were used to compare the OHRQoL between edentulous patients who had conventional removable complete denture on both jaws and those who had on either one of the jaws. RESULT: The age of the participants ranged from 42 to 75 years, with the mean age of 58 ± 8.12 years. The mean OHIP-EDENT scores were significantly high among those who wore conventional dentures in both jaws (54.12 ± 5.21), compared with the participants who only had denture either on upper or lower jaw (46.52 ± 7.35). It was noticed that the mean GOHAI score was significantly lower (p < 0.05) among participants who had conventional denture on both upper and lower jaw (28.25 ± 3.67), as compared to those who had conventional denture only on one arch (35.12 ± 2.11). CONCLUSION: Patients with complete dentures in both jaw (Group I) were less satisfied than patients with single complete denture (Group II). The result obtained in this study shows dissatisfaction with conventional dentures among edentulous patients.
