Artificial Intelligence (AI)-driven dental education: Exploring the role of chatbots in a clinical learning environment.

STATEMENT OF PROBLEM: Despite their widespread use in various educational contexts, the integration of chatbots into dental clinical education has not been thoroughly investigated. The noted discrepancy signifies a lack of understanding of how chatbots could enhance the personalized and interactive learning experiences of predoctoral dental students. PURPOSE: The purpose of this study was to evaluate the awareness and perceptions of artificial intelligence (AI) technology, interaction experiences, and concerns about a custom-developed chatbot (CB) intervention in the clinical education of predoctoral dental students at the University of Illinois Chicago, College of Dentistry (UIC-COD) compared with the traditional Blackboard (BB) online platform. MATERIAL AND METHODS: Eligible participants (n=86) providing verbal consent were allocated via the random block method into BB (n=43) and CB (n=43) groups and asked to engage with their designated platforms for 10 to 15 minutes by focusing on clinical inquiries in a predoctoral implant clinic and supported by a list of 35 typical questions. After the interaction, participants responded on a 5-point Likert scale to a 19-item survey probing AI awareness, platform engagement, and technological concerns. Survey data were anonymized and analyzed using descriptive, inferential statistics and nonparametric Mann-Whitney U tests to compare interventions. The Bonferroni correction for multiple comparisons was performed (α=.0045). RESULTS: Neither the BB or CB group showed any difference in their awareness and perception of AI technology. The CB group demonstrated improved timeliness (P<.001), more interaction (P<.001), reduced faculty workload (P=.001), enhanced receptiveness (P=.002), and less anxiety (P<.001) and was more satisfied (P<.001) when compared with the BB group. However, concerns regarding the potential for incorrect information (P=.003) were more pronounced in the CB group. CONCLUSIONS: The integration of chatbot technology into dental clinical education significantly enhanced learning and student engagement, highlighting the potential for future technological enrichment of the educational landscape.

Evaluating augmented reality e-typodont to improve a patient's dental implant health literacy.

STATEMENT OF PROBLEM: Information regarding dental implants can be difficult to understand for participants. Improving patients' dental implant health literacy remains a challenging process. PURPOSE: The purpose of this clinical study was to develop and evaluate patients' understanding of the implant treatment procedure, components, and sequences using traditional typodont and augmented reality (AR) applications (e-typodont), with the goal of improving their oral health literacy. MATERIAL AND METHODS: Participants who had sought dental implant treatment at the group practice and implant clinic at the University of Illinois Chicago (UIC) College of Dentistry were invited to enroll in this study. Participants were asked to fill out the first questionnaire (Q1) assessing their understanding of implant treatment procedures, components, and sequences. The participants were randomly exposed to 1 of the 2 modes of delivering education, typodont or AR e-typodont. The participants were asked to complete the additional 2 questionnaires (Q2 and Q3), and the posttest questionnaire (Q1) to re-evaluate their understanding of the implant treatment procedure, components, and sequences. All data were entered and coded into a spreadsheet. Descriptive (mean) and statistical (Wilcoxon Signed Ranks and Mann-Whitney U test) analyses were used (α=.05). RESULTS: Both interventions significantly increased participants' understanding of implant treatments (typodont: P=.004; e-typodont: P<.001), implant components (typodont: P=.003; e-typodont: P<.001), and implant treatment sequences (typodont: P=.001; e-typodont: P<.001). The e-typodont group significantly improved participants' understanding of implant treatments (P=.006), implant components (P=.023), and implant treatment sequences (P=.008) compared with the typodont group. Participants perceived the e-typodont mode of delivery to be significantly more interesting (P=.002), interactive (P=.008), educational (P=.002), user-friendly (P=.016), and "Wow" (P=.002) compared with the traditional typodont mode of delivery. CONCLUSIONS: Both interventions improved participants' understanding of implant treatment procedures, components, and sequences. The e-typodont showed better improvement in participants' understanding of dental implants compared with the traditional typodont.

Level of evidence and characteristics of clinical studies published in leading prosthodontics journals.

STATEMENT OF PROBLEM: Data on the level of evidence and the characteristics of studies published in peer-reviewed prosthodontic journals are lacking. PURPOSE: The purpose of this study was to investigate the characteristics and level of evidence (LOE) scores of studies published in 3 leading peer-reviewed prosthodontic journals. MATERIAL AND METHODS: Clinical studies published in the Journal of Prosthetic Dentistry (JPD), the Journal of Prosthodontics (JP), and the International Journal of Prosthodontics (IJP) in 2013 and 2020 were included in the analysis. Abstracts, letters to the editor, book reviews, and animal and laboratory studies were excluded from the investigation. For each study, design, type and LOE scores (Levels 1 to 5), publication year, impact factor (IF) of the journals, geographic origins of the first and corresponding authors, and funding status were recorded. Level 1 and Level 2 were defined as high evidence (HE), and Level 3, Level 4, and Level 5 were defined as low evidence (LE). Descriptive statistics and logistic regression analysis were performed (α=.05). RESULTS: Among the 439 studies included in the analysis, the proportion of HE and LE studies was 14.1% and 85.9%, respectively. According to univariate and multivariate analysis results, year of publication (P=.010 and P=.029), geographic origin of the corresponding author (P<.001), and funding status (P<.001 and P=.002) were significantly associated with the LOE of a study. However, the journal IF was not associated with LOE (P=.328). CONCLUSIONS: Although the number of HE studies in 3 leading prosthodontic journals has increased over time, the total number was still limited compared with LE studies. A further improvement in the overall LOE of clinical studies in prosthodontics is needed.

Profile of prosthodontics program directors in North America.

PURPOSE: To develop a current profile of prosthodontics program directors (PPDs) in United States dental schools and describe the current challenges and responsibilities of those serving in the position and assess the professional needs of the program directors (PDs) to better support them in their roles. MATERIALS AND METHODS: A survey was sent to 51 participants who were identified as PPDs in North America via Qualtrics in 2019 to assess the professional needs of PDs to better support their roles. The survey consisted of 29 items organized into six sections: (1) demographic information; (2) hours and time spent in various areas of the job; (3) greatest challenges; (4) perceived importance of specific competencies; (5) opinions on the greatest rewards of the position; (6) their needs for support from the American College of Prosthodontists and advice for the future PD. RESULTS: The response rate for this survey was 88.3%. Of the 45 respondents, the majority were white/non-Hispanic, followed by Asian/Pacific Islanders. The two largest and equal numbers of participants who worked for more than 10 years and between 1 and 3 years were observed with approximately 29% each, and PDs who worked less than a year occupied the least amount. Overall, 34% of PDs are on the tenure track and 80% of those are tenured. Teaching and clinical services took away the greatest time with approximately 42% and 22.1%, respectively. Thirty-five (78%) PDs listed the greatest challenge they encountered was the workload of the role. Skills listed in leadership and personnel competencies were all rated more important than most of the skills listed in management. CONCLUSIONS: There is a wide gender gap and a lack of racial diversity among the PPDs. The biggest challenge faced by them is the amount of workload followed by budget and fiscal constraints. And for their improved efficiency, they gave emphasis on learning time management and continuous clinical training of newer advances.

Attachment systems for mandibular implant-supported overdentures: A systematic review and meta-analysis of randomized controlled trials.

STATEMENT OF PROBLEM: Although mandibular implant-supported overdentures have been highly recommended as a treatment option, a consensus on the type of attachment systems that can be used to increase implant and prostheses survivability is lacking. PURPOSE: The purpose of this systematic review and meta-analysis was to compare different types of attachments for retention by investigating outcome measures such as implant and prosthesis survival rates and biological and prosthesis complications in participants with a mandibular implant-supported overdenture. MATERIAL AND METHODS: The search was performed in the PubMed, Cochrane, Embase, and Scopus databases by following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria and registered with the International Prospective Register of Systematic Reviews (CRD42021253566). An analysis of association was conducted between different attachment systems and implant and overdenture survival rates in randomized controlled clinical trials. RESULTS: The initial search indicated 477 studies, of which 25 randomized controlled trials (RCTs) were included for analysis. A total of 2154 implants and 737 overdentures were analyzed in the meta-analysis. The main results indicated the failure rate for dental implants to be 2.0% (95% confidence interval [CI], 1.3 to 3.2) and overdentures 4.2% (95% CI, 1.6 to 10.5), respectively. With regard to different attachment systems, a similar failure rate was identified with bar-type retention (7.7% to 95% CI, 3.0 to 18.1), magnetic retention systems (7.6% to 95% CI, 2.2 to 22.7), and ball-type retention (6.8% to 95% CI, 3.0 to 14.3). No significant difference was found in biological complications for splinted and unsplinted implant overdentures (P=.902). Regarding prosthetic complications, the most favorable groups were LOCATOR attachments followed by telescopic and Conus, bar, and ball attachments. Magnet attachments had higher prosthetic complications (7.4 times) than the other attachments. CONCLUSIONS: Implants and implant-supported mandibular overdentures showed a high survival rate irrespective of the attachment system used. Splinting implants did not significantly affect the rate of biological complications. Prosthetic complications were most common for magnet and least common for LOCATOR attachments.

Prosthodontic Resident Selection by Postdoctoral Dental Matching Program: A National Survey by Participating Program Director.

PURPOSE: The purpose of this study was to obtain information about the resident selection and Match process that occurred for the Commission on Dental Accreditation (CODA)-accredited Advanced Education in Prosthodontics program in North America from the program directors' perspective, after the first year of implementation. MATERIALS AND METHODS: The list of Advanced Education in Prosthodontics program in CODA-accredited North American institutions was obtained from the ACP central office, and the directors of each program were identified. The surveys were distributed to 48 program directors online and results were compiled. RESULTS: Out of 48 programs, 43 directors responded to and completed the survey (90.0%), where 35 programs participated in the Match process, 5 did not, and 3 were omitted due to incomplete surveys. While the majority of programs did not see any changes in their applicant pool or their quality, 10 programs (25.0%) observed a number of increases in the application and 13 programs (32.5%) observed an increase in the quality of the applications. Among the 35 programs that participated in the Match process, the main reasons for their participation were "fairness" (48.2%), "did not want to keep moving up interview dates" (23.2%), and "have applicants come to interview as planned" (21.4%). Thirty-three programs reported that 75% to 100% of the invited applicants came to the interview (76.7%). The majority of programs that participated in Match expressed satisfaction with the process (29/33, 80.6%). Sixteen programs (45.7%) reported that they matched with 100% of their first selections. CONCLUSION: Overall response of reintroduction of the Match process for advanced prosthodontic resident selection was very positive for majority of the program directors.

Status of Sleep Apnea and Snoring Disorder Curriculum in U.S. Advanced Education Prosthodontic Programs.

PURPOSE: To assess the management of sleep apnea and snoring disorders in Advanced Education Programs in Prosthodontics (AEPP) in the United States. MATERIALS AND METHODS: A 51 item, online survey was sent to program directors at 48 AEPPs in the United States in 2015. Data results were analyzed descriptively. RESULTS: Thirty-five program directors responded to the survey. Twenty-four (68.6%, N = 35) programs report not having a dedicated course for the treatment of sleep apnea and snoring disorders. The majority (94.3%) of programs chose to treat sleep disordered breathing with oral appliance therapy and 80.0% (N = 35) of programs utilize customized sleep apnea oral devices. However, only 48.6% (N = 35) and 51.4% (N = 35) of programs regularly address sleep apnea and snoring disorders at initial examination during the comprehensive exam and medical history questionnaire, respectively. CONCLUSIONS: The confidence interval for this survey is 8.71 at a confidence level of 95% due to a response rate of 72.9%. This confidence interval suggests there is responder bias in the survey results. Therefore, the results of this survey provide a suggestion of how sleep disorders are managed in AEPPs. Programs appear to be consistent among each other with regards to treatment modalities for sleep disordered breathing. The results suggest that patients are not screened enough to receive treatment addressing sleep disorders.

Color stability of maxillofacial prosthetic silicone functionalized with oxide nanocoating.

STATEMENT OF PROBLEM: Maxillofacial prostheses made of silicone elastomers undergo undesirable color degradation over time. How this color change can be prevented is unclear. PURPOSE: The purpose of this in vitro study was to evaluate the ability of an oxide nanocoating to prevent color degradation of maxillofacial silicone elastomers after artificial accelerated aging. MATERIAL AND METHODS: A silicone elastomer with functional intrinsic pigment was tested. Specimens (N=20) were fabricated, and half of them were coated with a nanolayer of titanium dioxide (TiO2) using atomic layer deposition. Both coated and noncoated specimens (control) were exposed to artificial aging at 450 kJ/m2 of total energy. Changes in the color of all the specimens with and without TiO2 nanocoating were measured before and after the atomic layer deposition coating and before and after aging. The obtained color data were analyzed by using independent t tests and the 1-sample t test (α=.05). RESULTS: Color change (ΔE1=3.4 ±1.4) was observed for the silicone elastomers after the specimens were surface coated with TiO2 nanofilm, although this change was not statistically significant (P=.369) compared with the acceptability threshold (ΔE=3.0). Upon exposure to artificial aging, the noncoated control specimens underwent color change (ΔE2=2.5 ±0.7, P=.083 compared with the acceptability threshold). The specimens with TiO2 nanocoated surface experienced the least color change (ΔE3=1.4 ±0.6) when subjected to artificial aging, and this change was significantly lower (P<.001) than the established acceptability threshold of ΔE=3.0. In addition, the chemical analyses confirmed that the TiO2 nanocoating remained on the surface after exposure to artificial aging. CONCLUSIONS: TiO2 nanocoating was shown to be effective in reducing color degradation of the silicone elastomer exposed to artificial aging for 120 hours with 450 kJ/m2 of total energy.

Wear Characteristics and Volume Loss of CAD/CAM Ceramic Materials.

PURPOSE: In the field of prosthodontics, patients often require complex and extensive restorative care. This can involve the use of dental restorations to restore teeth on both the maxillary and mandibular arch. Current literature has evaluated the wear properties of different dental ceramics against enamel, but studies regarding dental ceramics opposing one another are limited. The purpose of this study was to assess the wear potential and wear behavior of CAD/CAM zirconia (ZR) and lithium disilicate (LD) materials against a similar ceramic material, and how the surface finish of these dental ceramics might affect patterns of wear. MATERIALS AND METHODS: Using a sphere-on-plate tribometer system, different surface finishes (glazed-G and glazed then polished-GP) of ZR and LD were evaluated following wear simulation. Artificial saliva of physiologic pH was used as a lubricant during wear simulation at 37°C. The coefficient of friction (COF) was calculated during the wear simulation. After wear simulation was complete, volume loss, surface roughness, and surface characterization of the specimens were analyzed using white-light interferometry and scanning electron microscopy (SEM). Statistical significance between materials and surface finish was established with two-way ANOVA and Bonferroni post hoc test (α = 0.05). RESULTS: Based on the 2-way ANOVA, material (p = 0.002) significantly affected the COF. LD showed a higher COF (p = 0.002) than ZR. Material (p < 0.001) and surface finish (p = 0.004) significantly affected the surface roughness inside the scar. ZR had significantly lower surface roughness compared to LD (p < 0.001). For outside scar, surface finish (p < 0.001) significantly affected the surface roughness. Polished specimens showed significantly higher roughness compared to glazed specimens for both inside (p = 0.004) and outside scar (p < 0.001). For volume loss, material (p < 0.001) and the interaction between material and surface finish (p < 0.001) were statistically significant. LD had higher volume loss than ZR (p < 0.001). For both glazed and polished finished, LD-G and LD-GP had significantly higher volume loss than ZR-G (p = 0.028), and ZR-GP (p < 0.001), respectively. SEM analysis indicated particle build-up and a grooving mechanism of wear for the LD-GP specimens. This suggested a three-body wear phenomenon occurring for LD-GP specimens, which was not visible in SEM imaging for other specimen types. CONCLUSIONS: This study demonstrated the resistance to wear and low abrasiveness of ZR when compared to LD in a simulated masticatory environment. This can be best explained by the increased strength of ZR, and the introduction of three-body wear to LD specimens from the accumulation of embedded wear debris onto its surface. Wear data and comparison of SEM images following wear simulation confirmed this interpretation.

Patient-Specific, Risk-Based Prevention, Maintenance, and Supportive Care: A Need for Action and Innovation in Education.

PURPOSE: To develop a competency-based curriculum framework for prevention, supportive care, and maintenance for use in educational and patient care programs and to seek consensus on an overarching competency statement that embraces these critical learning and patient care concepts. MATERIALS AND METHODS: A preliminary survey of current preventive and maintenance practices in U.S. dental and prosthodontic programs was completed and summarized with quantitative analysis. The American College of Prosthodontists organized a one-day consensus workshop with 14 participants from various U.S. dental schools with diverse backgrounds to develop a curriculum framework. The curriculum framework was used in the development of a joint competency statement using an iterative, online consensus process of debate and feedback. RESULTS: The preliminary survey helped frame the initiative and identify potential educational needs and gaps. Consensus was achieved for a recommended competency statement: "Graduates must be competent in promoting oral health through risk assessment, diagnosis, prevention, and management of the hard tissue, soft tissue, and prostheses, and as part of professional recall and home maintenance." This competency statement complements the proposed curriculum framework designed around 3 domains-caries prevention, periodontal supportive care, and prosthesis supportive care-with a set of recommended learning objectives. CONCLUSIONS: Commission on Dental Accreditation (CODA) learning standards do not outline patient-customized, evidence-based recall and home maintenance programs that highlight prevention of dental caries, periodontal supportive care, prosthesis maintenance, and patient education. The proposed competency-based curricular framework serves as an initial step in addressing student learning and patient care within the context of a recall system and home maintenance program while offering schools the needed flexibility for implementation within their curriculum.

Effect of brushing and thermocycling on the shade and surface roughness of CAD-CAM ceramic restorations.

STATEMENT OF PROBLEM: The effects of toothbrushing (B) and thermocycling (TC) on the surface texture of different materials with various fabrication processes have been investigated. However, studies of computer-aided design and computer-aided manufacturing (CAD-CAM) ceramic restorations are limited. PURPOSE: The purpose of this in vitro study was to evaluate the effect of B and TC on the color stability and surface roughness of extrinsically characterized and glazed CAD-CAM ceramic restorations. MATERIAL AND METHODS: Lithium disilicate CAD ceramic (n=90) and zirconia ceramic (n=90) were studied. All specimens were crystallized/sintered, characterized, and glazed following the manufacturer's recommendation. The specimens were divided into 9 different groups: B, TC, and a combination of B plus TC (B+TC). Brushing was performed at 50 000, 100 000, and 150 000 cycles, simulating an oral environment of 5, 10, and 15 years. Thermocycling was performed at 6000, 12 000, and 18 000 cycles, simulating an oral environment of 5, 10, and 15 years. Brushing plus TC was performed with the combination of the 50 000 cycles of B, then 6000 cycles of TC, and 10 000 cycles of B, then 12 000 cycles of TC, and 15 000 cycles of B, then 18 000 cycles of TC. The color and surface roughness of each specimen were measured before and after all interventions with simulated cycles. Color differences (ΔE) and surface roughness (ΔRa) data were analyzed using 2-way ANOVA, followed by the least significant difference test (α=.05). The correlation between ΔE and ΔRa was statistically analyzed using the Pearson correlation analysis. RESULTS: Within the lithium disilicate CAD groups, intervention did not result in any significant differences in color change (P>.05). Within the zirconia groups, a 15-year clinical simulation revealed significantly higher ΔE values than a simulated 5-year exposure (P=.017). Increased simulated cycles showed significantly higher Ra values for all groups. Within the zirconia groups, B revealed significantly smoother surfaces than TC (P<.001) and B+TC interventions (P<.001). For the zirconia, simulating B+TC for15 years revealed significantly higher Ra values than the groups of B+TC for 5 years (P<.001) and B+TC for 10 years (P=.003). No correlation (lithium disilicate CAD, r=.079; P=.462; zirconia, r=.001; P=.989) was found between the color change and surface roughness. CONCLUSIONS: For both lithium disilicate CAD and zirconia, color changes were below the selected clinical perceptible threshold (ΔE=2.6) after all intervention and simulated cycles. All mean surface roughness measurements were below 0.2 µm. Generally, the surface of both lithium disilicate CAD and zirconia became rougher. No correlation was found between color difference and surface roughness for either material.

Wear and Corrosion Interactions at the Titanium/Zirconia Interface: Dental Implant Application.

PURPOSE: Dental implants have been shown to have predictable success, but esthetic complications often arise. To reduce tissue shadowing from titanium, zirconia abutments may be used; however, the literature suggests that the use of zirconia leads to greater destruction of the implant interface that may result in biological complications such as titanium tattoos and heavy metal toxicity. Previous studies have examined the mechanical aspects of this implant/abutment relationship, but they have not accounted for the corrosive degradation that also takes place in the dynamic environment of the oral cavity. This study investigated the combined effect of both wear and corrosion on the materials at the implant and abutment interface. MATERIALS AND METHODS: Using a simulated oral tribocorrosive environment, titanium (Ti) and zirconia (Zr) abutment materials were slid against titanium and Roxolid implant alloys. The four couplings (Ti/Ti, Ti/Rox, Zr/Ti, Zr/Rox) were selected for the tribocorrosion tests (N = 3). The testing was conducted for 25K cycles, and the coefficient of friction (CoF) and voltage evolution were recorded simultaneously. Following the tribocorrosion assays, the wear volume loss was calculated, and surface characterization was performed. Statistical analysis was completed using a one-way ANOVA followed by post-hoc Bonferroni comparisons. RESULTS: Zr/Ti groups had the highest CoF (1.1647), and Ti/Ti had the lowest (0.5033). The Zr/Ti coupling generated significantly more mechanical damage than the Ti/Ti group (p = 0.021). From the corrosion aspect, the Ti/Ti groups had the highest voltage drop (0.802 V), indicating greater corrosion susceptibility. In comparison, the Zr/Roxolid group had the lowest voltage drop (0.628 V) and significantly less electrochemical degradation (p = 0.019). Overall, the Ti/Ti group had the largest wear volume loss (15.1 × 107 µm3 ), while the Zr/Ti group had the least volume loss (2.26 × 107 µm3 ). Both zirconia couplings had significantly less wear volume than the titanium couplings (p < 0.001). CONCLUSIONS: This study highlights the synergistic interaction between wear and corrosion, which occurs when masticatory forces combine with the salivary environment of the oral cavity. Overall, the zirconia groups outperformed the titanium groups. In fact, the titanium groups generated 5 to 6 times more wear to the implant alloys as compared with the zirconia counterparts. The best performing group was Zr/Ti, and the worst performing group was Ti/Ti.

Maxillofacial prosthetics training and practice profiles in the United States.

STATEMENT OF PROBLEM: The motivation of maxillofacial prosthodontists to go into fellowship training and specific procedures in maxillofacial prosthetics practice once they have completed training has not been previously evaluated. PURPOSE: The purpose of this study was to survey maxillofacial prosthodontists in the United States to investigate their reasons for pursuing maxillofacial prosthetic training and their practice profiles. MATERIAL AND METHODS: In June 2015, a survey was sent to all US maxillofacial prosthodontists asking for descriptive demographics, their reasoning as to what prompted entrance into a maxillofacial prosthetic program, and their practice pattern. Frequencies, percentages, means, and standard deviations were calculated and reported. RESULTS: The survey response rate was 60.4%. The main reason for pursuing maxillofacial training was primarily personal satisfaction, prosthodontic residency exposure, and mentorship rather than media exposure and compensation. The time spent in prosthodontic practice varied among practitioners, with the majority of practice time spent accomplishing standard prosthodontic procedures (65.59%) versus maxillofacial (25.53%) or surgical procedures (9.67%). Of 12 clinical maxillofacial procedures inquired about, the most prevalent were obturators, dental oncology, and mandibular resections. CONCLUSIONS: This study reveals that personal satisfaction, mentorship, and prosthodontic residency exposure were the reasons most prosthodontists pursued an additional year of maxillofacial prosthetic fellowship. Most were very satisfied with their training and chosen career path and would recommend an additional year of training. The majority of maxillofacial prosthodontists provided maxillofacial prosthetic treatment for approximately one fourth of their practice time. The most common procedures performed were obturators, dental oncology, and mandibular resections.

Women in Prosthodontics: A Brief Look at Pioneers, Leaders, and Inspirers.

There are several women pioneers in prosthodontics, and each deserves recognition and admiration for all she has achieved in helping bridge the gender gap in dentistry. Women have come a long way from being first depicted as a thieving woman assistant in early 1523 to becoming award-winning, Board-certified clinicians, program directors, department chairs, and deans of dental schools. However, current female resident membership in the American College of Prosthodontists is less than 40%. Women in leadership roles are still scarce, and advancement is still needed. This article provides a brief summary of the history of prosthodontics, highlighting prominent women prosthodontists and their stories, while providing inspiration for future prosthodontists, men as well as women.

Electrochemical behavior of bioactive coatings on cp-Ti surface for dental application.

The surface characteristics and electrochemical properties of bioactive coatings produced by plasma electrolytic oxidation (PEO) with calcium, phosphorous, silicon and silver on commercially pure titanium were evaluated. PEO treatment produced a porous oxide layer, which improved the surface topography, and enriched the surface chemistry with bioactive elements, responsible for mimicking bone surface. The surfaces with higher calcium concentration presented antibacterial and biocompability properties with better responses for corrosion and barrier properties, due to the presence of rutile crystalline structure. PEO may be a promising surface treatment option to improve the electrochemical behavior of dental implants mitigating treatment failures.

Prosthodontics treatment considerations for methamphetamine-dependent patients.

Overt dental disease is a distinguishing comorbidity associated with methamphetamine abuse, necessitating the need for special management to maximize treatment benefits. As this highly addictive stimulant increases in popularity, it has become imperative that clinicians are equipped to thoughtfully provide comprehensive care for these patients. This article reviews the impact of methamphetamine to systemic and oral health and proposes a comprehensive treatment plan and sequence for the methamphetamine-dependent patient. A multidisciplinary approach is recommended. Destructive oral and psychological changes must be identified and controlled. A thorough risk assessment, caries control, and preventative plan should be established before initiating prosthodontic treatment. Patient motivation, support, and a timely recall schedule are integral for dental longevity.

Prosthodontic Implant Club at UIC, Program Description and Survey Analysis.

PURPOSE: This study aims to (1) describe the Predoctoral Implant Club at UIC (PIC-UIC) mentoring model while providing a rationale for the program and (2) investigate PIC members' perception about the club and prosthodontics in general via a questionnaire and focus group discussion. MATERIALS AND METHODS: A survey to investigate PIC members' perception regarding the club was distributed at a meeting. The survey consisted of questions about the members' prior exposure to prosthodontics, faculty, and residents; current exposure to and perceptions of prosthodontics; future outcomes from membership; and possible improvements to PIC-UIC. Four student members of PIC-UIC participated in a focus group discussion about their exposure to prosthodontics during each year of their training, their exposure to prosthodontics following PIC-UIC membership, including rotations in the advanced prosthodontic clinic, mentorships by prosthodontic faculty and residents, and attendance at the American College of Prosthodontists Annual Session. RESULTS: Following PIC-UIC membership, students indicated an increased exposure to prosthodontics and prosthodontic faculty. More than a third of the respondents indicated that they are "likely" to consider a prosthodontic residency after having joined PIC-UIC. Almost two-thirds of the respondents indicated that they would recommend PIC to students at other universities and believed their understanding of the prosthodontic specialty has increased. Students who participated in the focus group agreed they had little exposure to prosthodontics, prosthodontic faculty, and advanced restorative procedures in the beginning of their dental education. They felt that involvement in PIC-UIC was a valuable experience that helped them consider or reinforced their decision to pursue prosthodontics as a career. CONCLUSIONS: PIC-UIC increased predoctoral students' interest in prosthodontics. Involving prosthodontic faculty and residents in mentoring and educational activities was evaluated positively by students. PIC-UIC may serve as a pipeline program for predoctoral students at other dental schools.

Patient Perception and Satisfaction with Implant Therapy in a Predoctoral Implant Education Program: A Preliminary Study.

PURPOSE: The purpose of this study was to assess the level of satisfaction and quality of life for patients receiving mandibular implant-supported overdenture (IOD) or single-tooth implant (STI) therapy in a predoctoral dental implant program. MATERIALS AND METHODS: Patients who received IOD and STI therapy and presented for recall visits at University of Illinois-Chicago College of Dentistry Predoctoral Implant Program were recruited. IOD treatment included placement of two endosseous implants in the mandibular canine region, followed by two abutments for resilient attachments. STI treatment included placement of endosseous implants, abutments, and cement-retained crowns. A modified Oral Health Impact Profile (OHIP)-14 questionnaire was given at least 6 months following insertion of implant-supported prostheses for both groups. Patient age, gender, distribution of STI, and OHIP-14 data were gathered and analyzed. Descriptive statistics were used to assess post-treatment data; Mann-Whitney U test was used to analyze the differences between groups older and younger than mean age and gender among the IOD and STI groups. RESULTS: Fifty-one consecutive patients in the IOD (60.7% male, 39.2% female, mean age 63.7) and 50 consecutive patients in the STI group (58.0% female, 42.0% male, mean age 50.8) were included in this recall study. In the STI group, 69 implants were placed for 50 patients; the most common region was the maxillary posterior quadrant (49.3%). Scores from modified OHIP-14 ranged from 0.14 to 0.78 for the IOD group and 0.02 to 0.18 for the STI group. Both IOD and STI data showed satisfaction with the treatment outcome. There was a significant difference found between men and women among the IOD group pertaining to questions regarding pronouncing words, sense of taste, meal interruption, and feeling embarrassed from OHIP-14, but not between the age groups. Also, no significant differences were noted for gender or age group within the STI patients and OHIP-14 scores. CONCLUSION: Dental implant therapy provided in a predoctoral setting had a significant impact on the quality of life and a high level of satisfaction for patients seeking implant treatment.

Clinical Experience Comparison of Foreign-Trained Dentists and Domestic Dental Students: One Institution's Experience.

This study compared the clinical experiences of foreign-trained dentists (FTDs) enrolled in an Advance Standing DMD Dental Program (DMDAS) with those of the domestic dental students (DMD) at the University of Illinois Chicago, College of Dentistry (UIC-COD). A cross-sectional retrospective chart review of patients treated by 295 DMD and 253 DMDAS predoctoral dental students was completed at the UIC-COD. The data were retrieved from the electronic health record system (axiUm) for the graduated classes of 2018, 2019, 2020, 2021, and 2022 on various performed clinical procedures as measured by relative value units (RVUs). The retrieved data were used to compare the clinical experiences of DMDAS vs. DMD students. Descriptive (mean) and statistical (independent t-test) analyses were used (α = 0.05). The results indicated that DMD and DMDAS students had comparable clinical experiences in several disciplines, including diagnosis, prevention, direct/indirect restorations, endodontics, periodontics, complete dentures, removable partial dentures, implants/fixed partial dentures, and oral surgery. There was a statistical difference in total RVUs for diagnosis (p = 0.002) and direct restorations (p < 0.001), in which DMD students had more experience. The 28 month program for FTDs appeared to be a reasonable timeframe to obtain an adequate number of varied clinical experiences as compared with the traditional four-year program at the UIC-COD.

Development and integration of a clinical dashboard within a dental school setting.

PURPOSE: To describe the development and integration of an electronic health record-driven, student dashboard that displays real-time data relative to the students' patient management and clinic experiences at the University of Illinois Chicago, College of Dentistry. MATERIALS AND METHODS: Following development and implementation of the student dashboard, various objective metrics were evaluated to identify any improvements in the clinical patient management. A cross-sectional retrospective chart review was completed of the electronic health record (axiUm, Exan, Coquitlam, BC, Canada) from January 2019 to April 2022 evaluating four performance metrics: student lockouts, note/code violations, overdue active patients, and overdue recall patients. Descriptive statistics were analyzed. The Kolmogorov-Smirnov test was applied to assess the normal distribution of data. Data were analyzed by the Kruskal-Wallis tests for potential differences between pre-dashboard and post-dashboard implementation years with the mean overdue active/recall patient to student ratio variables. Mann-Whitney U-tests for between-groups comparisons with Bonferroni correction for multiple comparisons were performed (α = 0.05). Descriptive statistics were performed to analyze the student utilization frequency of the dashboard. RESULTS: Post-implementation analysis indicated a slight decrease in the number of lockouts and note/code violation; and a statistically significant decrease in overdue active patients post-dashboard (P < 0.001). On average, students accessed their dashboards 3.3 times a week. CONCLUSIONS: Implementation of a student dashboard through the electronic health record platform within an academic dental practice has the potential to assist students with patient management and is utilized regularly by the students.
