The Extent and Scope of Prosthodontic Practice in Iowa.

PURPOSE: The purpose of this questionnaire was to ask general dentists in private practice in the state of Iowa about the extent and scope of their prosthodontic practice. MATERIALS AND METHODS: A 22-item questionnaire was developed and tested on 5 general dentists. The Iowa Dental Association agreed to electronically distribute the survey to all general practice dentists in their database. After three rounds, a total of 289 responses were received from the 996 general dentists in the database. RESULTS: The average age of the respondents was 50.3 ± 13.2 years (range 28 to 78 years), and 56.3% were in solo practice. The respondents stated that 68.1% had made at least one set of complete dentures and 88.9% had made a removable partial denture (RPD) in the last 3 months, while 76.4% had restored a least one implant in the last 3 months and 11.6% had surgically placed one. Nearly 20% of the respondents had a digital impression scanner in their office. There was a statistically significant difference between the dentists who had made complete dentures in the past 3 months and those who had not with regard to age, gender, and years in practice (p < 0.05 for all instances). No significant difference was found between the general dentists who had made an RPD in the past 3 months and those who had not. Compared to their counterparts, general dentists who had an AEGD or GPR training (p = 0.0312), whose primary practices were in cities of 50,000+ (p = 0.0065), or had a digital scanner (p = 0.0062) and a CAD/CAM milling machine (p = 0.0504) in their office were more likely to have restored an implant in the last 3 months. Furthermore, the general dentists who had surgically placed an implant in the last 3 months were more likely to be male (p = 0.0301) or have a digital impression scanner (p < 0.0001) and/or a CAD/CAM milling machine (p = 0.0007) in their office. CONCLUSIONS: The majority of general dentists in this survey are still making complete and partial removable dentures, and a majority is using implants, while only a minority is surgically placing them. PRACTICAL  IMPLICATIONS: Although Iowa general dentists are carrying out sophisticated procedures such as implant placement and restoring implants, as well as using digital technology, there is still a need for removable prosthodontic services in their practices. Therefore, these skills will still need to be taught in dental school.

Patterns of impaired oral health-related quality of life dimensions.

How dental patients are affected by oral conditions can be described with the concept of oral health-related quality of life (OHRQoL). This concept intends to make the patient experience measurable. OHRQoL is multidimensional, and Oral Function, Oro-facial Pain, Oro-facial Appearance and Psychosocial Impact were suggested as its four dimensions and consequently four scores are needed for comprehensive OHRQoL assessment. When only the presence of dimensional impact is measured, a pattern of affected OHRQoL dimensions would describe in a simple way how oral conditions influence the individual. By determining which patterns of impact on OHRQoL dimensions exist in prosthodontic patients and general population subjects, we aimed to identify in which combinations oral conditions' functional, painful, aesthetical and psychosocial impact occurs. Data came from the Dimensions of OHRQoL Project with Oral Health Impact Profile (OHIP)-49 data from 6349 general population subjects and 2999 prosthodontic patients in the Learning Sample (N = 5173) and the Validation Sample (N = 5022). We hypothesised that all 16 patterns of OHRQoL dimensions should occur in these individuals who suffered mainly from tooth loss, its causes and consequences. A dimension was considered impaired when at least one item in the dimension was affected frequently. The 16 possible patterns of impaired OHRQoL dimensions were found in patients and general population subjects in both Learning and Validation Samples. In a four-dimensional OHRQoL model consisting Oral Function, Oro-facial Pain, Oro-facial Appearance and Psychosocial Impact, oral conditions' impact can occur in any combination of the OHRQoL dimensions.

Assessment of 68 Prosthodontic Crowns in 41 Pet and Working Dogs (2000-2012).

A search of the medical and dental records at the Matthew J. Ryan Veterinary Hospital of the University of Pennsylvania was conducted to identify dogs that received full or partial prosthodontic crowns over a 13-year period (2000-2012). Forty-one dogs with a total of 68 prosthodontic crowns were identified. Further criteria for acceptance into the study included presence of complete medical records containing adequate information pertaining to the procedures performed, and current follow-up either by telephone, electronic mail, or via in-person examination. Treatment was considered to be successful when the prosthodontic crown was in place and there was no further structural injury to the tooth upon making contact with the client or at the time of death of the dog confirmed by the client. The mean number of days the prosthodontic crowns remained in place without further injury to the tooth was 1,598 (range, 161-4, 464 days [median, 1,414 days], standard deviation 1,093 days). Bond failure between the cement and the tooth or the cement and the prosthodontic crown occurred in 3 cases (4.4%). Fracture of the prosthodontically treated tooth occurred in an additional 7 cases (10.3%). Treatment was classified as successful in 58 cases (85.3%). The results suggest that prosthodontic crown therapy is a successful, practical, and durable treatment option for protection of previously injured teeth in pet and working dogs.

Use of implant-supported prostheses in edentulous mandibles among prosthodontists in Sweden.

The aim of this study was to investigate the production of mandibular implant-supported fixed and removable prostheses among prosthodontic specialists in Sweden and to compare the results with findings in a similar study made in 2001 (17). Questionnaires regarding treatment with mandibular implant prostheses during 20011 were mailed to all specialists in prosthodontics in Sweden (n = 156, according to available data). Of the 156 questionnaires, 129 (83%) were returned and of those 114 were completed. The reported number of treatments with mandibular implant-supported prostheses varied much among the specialists. Fixed implant prostheses were more common than overdentures (means 11 and 3, median values 8 and 2, respectively). However, the range was large for both alternatives. Ten (9%) of the specialists reported no treatment with fixed implant prostheses while 29 (25%) had not made any implant overdenture during 2011. The most common anchorage system for overdentures in 2011 (as well as in 2001) was two un-splinted implants with ball attachments or Locator abutments. The most common reasons for choosing overdenture treatment instead of a fixed implant prosthesis in 2011 were the reduced cost and the patient's main wish to improve denture retention. A majority of the prosthodontists (58%) reported that patients with implant overdentures were as satisfied as those with fixed implant-supported prostheses, whereas 40% claimed they were less satisfied. Two respondents (2%) considered that overdenture patients were more satisfied than those with a fixed prosthesis. It can be concluded that the general attitude among Swedish prosthodontists towards implant overdentures has not changed much during the 10-year period between the present and the previous investigation.An overdenture is still a seldom-used option in implant treatment of patients with edentulous mandibles in Sweden. Instead, a fixed implant-supported prosthesis continues to be the preferred option,

Private practice of prosthodontists in the United States: results from the 2008 & 2011 surveys of prosthodontists.

PURPOSE: The purpose of this article is to review data and results from past surveys of prosthodontists sponsored and conducted by the American College of Prosthodontists. Surveys were conducted in 2002, 2005, 2008, and 2011. Selected survey results are examined for prosthodontists in private practice. MATERIALS AND METHODS: Results from past surveys of prosthodontists were statistically examined and used to estimate several characteristics of the current population of practicing prosthodontists. The selected characteristics included age, gender, number of patient visits, hours in the practice, employment of staff, referral sources, and financial conditions (e.g., gross receipts, expenses in the practice, and net income of prosthodontists). While the most recent survey was conducted in 2011, the results reported by respondents are for the previous year, 2010. RESULTS: The average age of a private practicing prosthodontist in 2010 reached 53 years; 26 years since graduation from dental school and 20 years since completion of residency; an average of 13 years in their current practice. Sixty percent were in solo practice. The mean number of hours per week in the practice was 35 hours, and practicing prosthodontists treated an average of 35 patient visits per week. The patient was the single largest source of referrals, while general practitioners were a close second. The largest percentage of time spent treating patients was for fixed prosthodontics (21%), which declined from a mean of 24.1% in 2007. The mean amount of gross billings in 2010 was $721,970, which was a decline from 2007. Average total practice expenses were $538,230, and the mean net earnings of prosthodontists in private practice were $238,010. CONCLUSION: Changes have occurred since the last survey of prosthodontists in 2008 (with results for the year 2007). The prosthodontist private practice industry, not unlike dentistry as a whole, has undergone economic challenges that have affected the private practice of prosthodontists.

Predoctoral dental students' perceptions and experiences with prosthodontics.

PURPOSE: The aims of this study were to: (1) investigate the perceptions and experiences of predoctoral dental students and advanced standing students on mentorship, exposure to prosthodontics, and future need for the specialty, and (2) establish a baseline of students' perceptions of the impact of prosthodontics on salary, personal and patient quality of life, and the profession of dentistry. MATERIALS AND METHODS: A survey was distributed to 494 predoctoral and advanced standing students at the University of Pennsylvania School of Dental Medicine. Questions focused on the perceptions and experiences with the specialty of prosthodontics. A total of 410 surveys were analyzed using Chi Square tests and univariate and multivariate analysis with statistical software. RESULTS: Response rate was 83%. A positive initial introduction to prosthodontics was reported by 57% of students. Most students had positive experiences with prosthodontic faculty and enjoyed laboratory work and challenging/complex dentistry. A greater need for prosthodontists in the future was perceived by 82% of respondents, with 63% reporting that the future of prosthodontics had been emphasized. Students reported (1) a preclinical course directed by prosthodontists and (2) working in the clinic with prosthodontic faculty (p < 0.006) as having the biggest impact on their introduction to prosthodontics. A desire to pursue training or a career in prosthodontics was reported by 3.4% of the respondents, with 1.7% of them pursuing prosthodontics. Enjoyment of providing care in prosthodontics was the most important factor for those who decided to pursue prosthodontic postgraduate training. When compared to other specialties, prosthodontics ranked low with regards to its impact on salary (7(th) ), personal quality of life (5(th) ), patient quality of life (4(th) ), and strengthening of the dental field (7(th) ). CONCLUSION: Reasons few students are interested in prosthodontics as a career, despite a positive first introduction and high perceived future need for prosthodontists may be attributed to a number of factors. These include insufficient prosthodontically, trained faculty, lack of a mentorship program, lack of an advanced graduate program, a perception of feeling unprepared upon graduation, and misconception of potential income in prosthodontics.

Prosthetic modalities used to treat cleft palate patients in a university clinic: a 10-year review.

Cleft palate patients are not usually seen in general dental clinics, but this congenital anomaly is one of the most frequent of cases. General dental practitioners are usually unwilling or/and not sufficiently trained to treat such patients for whom rehabilitation and interdisciplinary cooperation is often needed. The aim of this study was to determine the incidence of prosthetic modalities most frequently used by licensed prosthodontists for prosthetic rehabilitation of cleft palate patients. Participants in this study were 56 cleft palate patients (aged 23-66 years) who received prosthetic treatment between 2000 and 2010. Patients' dental status and prosthetic modalities used were noted from patient records archived at Department of Prosthodontics, School of Dental Medicine, University of Zagreb. Data analyses revealed that combined prosthetic constructions (fixed + removable, p < 0.05) were the most frequently used. In a group of molar teeth, the most frequent fixed prosthetic modalities were crowns with rests; in a group of premolar teeth, telescopic crowns; on canines, metal ceramic crowns and telescopic crowns; and in a group of incisors, metal ceramic pontics (p < 0.05). Understanding the distribution of prosthetic modalities for cleft palate patients could serve to guide dental practitioners towards planning adequate prosthetic treatment for their patients since only a well-planned prosthetic therapy will result in satisfactory function and alleviation of the deformities.

Ergonomics and musculoskeletal disorder: as an occupational hazard in dentistry.

OBJECTIVE: Musculoskeletal disorders (MSDs) are commonly experienced in dentistry. The objective of this study is to determine the prevalence of ergonomics and MSDs among dental professionals. MATERIALS AND METHODS: A cross-sectional survey was conducted among 170 dentists of different specialties. The questionnaire gathered information regarding demographic details, MSDs, work duration, working status, awareness of ergonomics, etc. Data was analyzed using SPSS version 15.0. Student's t-test and analysis of variance (ANOVA) test was used for comparison in mean scores. Stepwise multiple linear regression analysis was used to assess the independent variables that significantly influenced the variance in the dependent variable (pain). RESULTS: It was found that 73.9% of the participants reported musculoskeletal pain and most common painful sites were neck and back. More than half of the participants, i.e. 232 (59.3%) were aware of correct ergonomic posture regarding dental. Almost percentage of pain increased significantly with increase in age and working time. Among all specialties, prosthodontics were found to have more prevalence of MSDs. CLINICAL SIGNIFICANCE: The appearance of musculoskeletal symptoms among dental professionals was quite common. It suggested that ergonomics should be covered in the educational system to reduce risks to dental practitioners.

Assessment of occlusion curriculum in predoctoral dental education: report from ACP Task Force on Occlusion Education.

PURPOSE: The purposes of this report were to (1) assess the current occlusion curriculum in the predoctoral prosthodontic education of US dental institutions and (2) to examine the opinions of faculty, course directors, and program directors on the contents of occlusion curriculum. MATERIALS AND METHODS: The Task Force on Occlusion Education from the American College of Prosthodontists (ACP) conducted two surveys using a web-based survey engine: one to assess the current status of occlusion education in predoctoral dental education and another to examine the opinions of faculty and course directors on the content of occlusion curriculum. The sections in the surveys included demographic information, general curriculum information, occlusion curriculum for dentate patients, occlusion curriculum for removable prosthodontics, occlusion curriculum for implant prosthodontics, temporomandibular disorder (TMD) curriculum, teaching philosophy, concepts taught, and methods of assessment. The results from the surveys were compiled and analyzed using descriptive statistics. The results from the two surveys on general concepts taught in occlusion curriculum were sorted and compared for discrepancies. RESULTS: According to the predoctoral occlusion curriculum surveys, canine guidance was preferred for dentate patients, fixed prosthodontics, and fixed implant prosthodontics. Bilateral balanced occlusion was preferred for removable prosthodontics and removable implant prosthodontics. There were minor differences between the two surveys regarding the occlusion concepts being taught and the opinions of faculty members teaching occlusion. CONCLUSION: Two surveys were conducted regarding the current concepts being taught in occlusion curriculum and the opinions of educators on what should be taught in occlusion curriculum. An updated and clearly defined curriculum guideline addressing occlusion in fixed prosthodontics, removable prosthodontics, implant prosthodontics, and TMD is needed.

A 10-year survey of US deans: trends, challenges, and mentoring in prosthodontics. Part 2.

PURPOSE: Part 2 of this survey reports on the 2009 survey findings distributed to the deans of US dental schools. A national, electronic survey of 58 dental school deans was distributed by e-mail to evaluate an interest in specialty training, an interest in specialty training in prosthodontics, faculty shortage issues, predoctoral curriculum in prosthodontics, ideology regarding dental specialties, and the administrative position of prosthodontics within the schools. MATERIALS AND METHODS: The survey data were transferred to an online spreadsheet program for statistical analysis (Key Survey, Inc. http://www.keysurvey.com, Braintree, MA). The opinions of dental school deans were viewed as legitimate indicators of change within predoctoral and postdoctoral prosthodontic education. Statistical analysis was carried out using Statistica Version 9.1 (Statsoft, Tulsa, OK). RESULTS: Of the 58 deans, 42 deans responded, for a 72.4% response rate. Twenty-three deans reported an increase in the number of students seeking specialty training after dental school. Only three deans reported a decrease in those seeking specialty training. In the 2009 survey, 45% the deans responded that there was an increased interest in prosthodontics. One or more open faculty positions in prosthodontics existed at 24 (59%) of the dental schools, and 30 (71%) offered at least one incentive or a variety of incentives to recruit faculty. The 2009 respondents to the deans' survey revealed predoctoral student exposure to prosthodontists was high, and exposure to advanced education in prosthodontics students was low. A survey of internal school programs that might have an impact on an increased interest in prosthodontics revealed the presence of a predoctoral mentoring program for prosthodontics in 36 (88%) of the institutions. The clinical curriculum included treatment of a variety of cases including complex cases as defined by a diagnostic classification system. The 2009 survey respondents reported an increase in the number of schools where prosthodontics is a separate entity or department. CONCLUSION: Deans reported an increased interest in prosthodontics in the 2009 survey. Open faculty positions in prosthodontics existed in the majority of dental schools, and most schools offered incentives to recruit faculty. The survey of deans found a very high level of exposure of dental students to full-time prosthodontists and a very low exposure level to students enrolled in advanced education in prosthodontics. The establishment of mentoring programs in prosthodontics was reported by most deans, and the predoctoral curriculum included treating complex cases. Most deans stated that dual-specialty training in prosthodontics and periodontics would be beneficial. The 2009 survey reported an increase in the number of departments of prosthodontics in US schools.

An analysis of prosthodontic research productivity: geographic, economic, and collaborative perspective.

PURPOSE: This study evaluated the quantity of prosthodontic literature produced globally by continent in three prosthodontic journals over a 10-year period, 1998-2008. Prosthodontic research productivity relative to economic status of countries and collaboration among countries grouped by economic status was assessed. MATERIALS AND METHODS: Three peer-reviewed prosthodontic journals were used for the analysis of articles published in 1998, 2003, and 2008: The Journal of Prosthetic Dentistry, International Journal of Prosthodontics, and Journal of Prosthodontics. The country of every author listed for each included article was recorded. The number of articles published by each continent and each country was reported. Countries were grouped according to the World Bank economic classification system, and the number of articles published by each economic class was found. RESULTS: The majority of publications over the 10-year period were produced in Asia (Japan), Europe (Germany), and North America (USA). Productivity declined by 14.4% in high-income countries while it increased in upper middle-, lower middle-, and low-income countries. The majority of publications written by upper and lower middle- and low-income countries were independent works. Articles resulting from collaboration increased over time for all economic classes of countries. CONCLUSIONS: The origins of prosthodontic literature are becoming more geographically and economically diverse, with increased contributions from Africa, Asia, and South America, and middle- and low-income countries between 1998 and 2008. Collaboration between high-income countries and the other economic group countries increased over time.

Surgical placement of implants--experiences, practices and opinions of South African prosthodontists.

UNLABELLED: It is generally accepted that dental implant-treatment is "restorative" driven: the virtual blueprint of a prosthesis determines the position and number of implants to be placed. Competent interdisciplinary team-work is essential for the successful completion of implant-retained restorations. The purpose of this survey was to determine the experiences, practices and opinions in terms of the surgical placement of implants among South African prosthodontists. METHODS: A questionnaire was e-mailed to a sample of South African prosthodontists. Data were collated and analysed using Epilnfo. Statistical significance was set at 0.05 and strength of association was determined by means of measurement of relative risk (RR) and chi-squared test or Fisher's exact test. RESULTS: The response rate was 49%. The majority of respondents were male. Mean age was 50 years and all treated patients with implant-supported prostheses. Most implants were placed by non-prosthodontists (surgeons/ periodontists) and the majority of prosthodontists reported that they were generally satisfied with implant placement by other specialities. Six prosthodontists reported that they surgically place implants themselves. Of those not placing implants, five reported that they would like to do so. Younger prosthodontists, those who had attended short courses and those who considered their "surgical training" to be adequate, were more likely to place implants themselves or to want to do so. CONCLUSION: This survey identified areas for further research into the dynamics that may cause changing habits in the management of implants in prosthodontic practices, and carries the mplication that the scope of practice of the different specialities should be continuously evaluated and adapted, to the ultimate benefit of the patient.

Foreign-trained dentists in advanced education in prosthodontics programs in the United States: demographics, perspectives on current training, and future goals.

PURPOSE: This study investigated the perspectives of foreign-trained dentists (FTDs) in comparison with US-trained Dentists (USTDs) in Advanced Education in Prosthodontics (AEP) programs on their current clinical training and future goals. MATERIALS AND METHODS: This study was conducted by analyzing data from previously published literature. When appropriate, Chi-square statistical analysis was conducted to determine the influence of where the AEP residents earned their DMD/DDS degree (FTDs/USTDs) on all variables. Only results that yielded significant differences were discussed. RESULTS: A majority of both FTDs and USTDs were male. Most USTDs were married, while most FTDs were single. Most FTDs were not US citizens and most originated from Asia, followed by the Middle East, South America, and Europe. Significantly more FTDs had higher ranks in their dental schools, had more advanced degrees, and spent more time practicing before entering the AEP programs. In selecting AEP programs, FTDs placed significantly higher values on a program's reputation and research opportunities. During their AEP training, FTDs paid significantly higher tuition and received lower stipends, but obtained more financial support from families. On the other hand, USTDs received significantly more financial aid and earned income from part-time work, but had significantly higher total educational debts. USTDs showed a significantly higher interest in becoming a student member of the American College of Prosthodontists and participated actively in prosthodontics organizations. USTDs were more interested in becoming maxillofacial prosthodontists, while FTDs were more interested in pursuing academic careers. CONCLUSION: FTDs differed from USTDs in several ways. Because of their interests in academics and research, FTDs may potentially have a positive impact on the development of the prosthodontics discipline. This information may be beneficial for AEP program directors in accommodating the needs of FTDs, and for FTDs in better preparing for their AEP training.

Gender disparities in prosthodontics: authorship and leadership, 13 years of observation.

PURPOSE: The purpose of this study was to examine gender disparities in prosthodontics by reviewing the trend of female authorship in prosthodontic journals and exploring the role of female leadership in prosthodontic organizations and Advanced Education in Prosthodontic (AEP) programs. MATERIALS AND METHODS: Three journals representing the prosthodontic specialty were selected to analyze the percentage of female dentist first and last (senior) authors for the years 1995, 2000, 2005, and 2008. Article inclusion criteria were restricted to the first or last authors who held at least a DMD/DDS/BDS degree and were from U.S. institutions. Data on female leadership in prosthodontic organizations and advanced education programs were collected, and the trends were studied. Descriptive statistics were used to analyze the data. A linear regression analysis was performed to investigate the proportion of female authorship compared to male in the dental literature. A Fisher's Exact Test was performed to contrast differences of female first and last authorship in the selected journals between years 1995 and 2008. RESULTS: Overall, there was no statistically significant linear increase in the proportion of either first or last female authorship compared to male authorship over time. With respect to each journal, the linear regression analysis showed that the increase of first female authorship was statistically significant (p= 0.016) compared to male authorship only in the Journal of Prosthetic Dentistry. The percentage of female presidents of prosthodontic organizations has been very limited. A similar trend was also observed in AEP program director positions. CONCLUSIONS: Over the past 13 years, female dentists' participation in prosthodontics literature authorship has not increased significantly in the United States. Furthermore, female involvement in prosthodontics leadership has been limited over the past decades.

Residents' perceptions of implant surgical training in advanced education in prosthodontic programs.

PURPOSE: The purpose of this study was to assess residents' perspectives on their implant surgical training in Advanced Education in Prosthodontic programs in the United States. MATERIALS AND METHODS: Questionnaires were distributed to all prosthodontic residents (N = 442). The 27 questions assessed the subjective and objective aspects of implant surgical training from the view of prosthodontic residents. The data were compiled and reported as frequencies. Descriptive statistics were used to analyze the data. RESULTS: One hundred and ninety-eight responses (44.8%) were received and analyzed. Forty-seven percent (94) of the respondents felt that the philosophy of their programs regarding implant placement in prosthodontics was "optional but encouraged," whereas 30% (60) felt that it was "mandatory." The majority of the respondents (73%, 144) stated that their programs allowed them to place implants for their own patients. For those respondents who placed their own implants, 40% (58) of them indicated that the level of their clinical training was "competent." Almost half of the respondents expressed that they would like to have a proficient level of clinical training in implant surgery by the completion of their residency programs. Forty-four percent (87) of the respondents felt their residency training adequately prepared them for implant surgery, whereas the other 37% (73) did not. For those who did not, 74% (55) felt their residency programs should have prepared them for implant surgical training. CONCLUSION: The current generation of prosthodontic residents has an opportunity to place implants in their programs and would like to be trained in surgical aspects of implant dentistry at the level of competency or higher.

2008 Survey of Pro Bono Services Provided by Practicing Prosthodontists.

PURPOSE: The purpose of this article is to analyze data from the results of the 2008 Survey of Pro Bono Services Provided by Practicing Prosthodontists. Survey results are used to examine characteristics and to compare the charitable care rendered by practicing prosthodontists to the dental field at large. MATERIALS AND METHODS: The character and incidence of pro bono services (PBS) provided by prosthodontists are based on a 2008 survey, made possible through an American College of Prosthodontists Board of Directors' sponsored initiative. Survey results are used to assess the distribution of respondents practicing the specialty of prosthodontics in the United States, percentage of prosthodontists who render pro bono dental services for the community, percentage of total patient care devoted to pro bono treatment at no charge, number of patients treated annually with PBS, monetary value of pro bono care annually, types of pro bono procedures, percentage of practitioners using Prosthodontic Diagnostic Index (PDI), PBS by PDI category to assess complexity of donated work, and percentage of practicing prosthodontists using informatics to track services by the PDI. RESULTS: Thirty-nine states were represented in the survey data. The highest responses were in the most populous states. The percentage of practicing prosthodontists providing PBS was 71.7%. For this cohort, the annual percentage of total care provided for treatment at no fee was greater than 1% in more than 54.8% of the practices. Almost 50% of these prosthodontists reported treating more than five patients per year at no charge. The average annual value of donated services was $25,078.00. The types of services rendered were most frequently diagnostic (83.5%) and radiographic (76.6%), followed by operative dentistry (61.5%) and fixed prosthodontics (49.4%). The percentage of practicing prosthodontists using the PDI to establish the complexity of PBS was 17.9%. For those using the PDI, there was almost an even distribution in categories I-IV. Informatics was used to track PBS in only 3% of the respondents. CONCLUSION: Based on this survey, practicing prosthodontists compare favorably to dental generalists and other specialists in terms of the annual dollar value donated in pro bono care. Their treatment addresses a broad scope of prosthodontic services including the restoration of patients with complex needs.

Private practice of prosthodontists: current conditions of practice in the United States.

PURPOSE: The purpose of this article is to examine data and results from the 2008 Survey of Prosthodontists. Survey results are used to examine current trends and characteristics of prosthodontists in private practice. MATERIALS AND METHODS: Characteristics of prosthodontists and conditions of private practice are based on surveys conducted in 2002, 2005, and 2008 sponsored by the American College of Prosthodontists. Survey results are used to estimate several characteristics including age, gender, number of patient visits, hours in the practice, employment of staff, referral sources, and financial conditions (gross receipts, expenses of the practice, and net income of prosthodontists). RESULTS: The average age of a private-practicing prosthodontist reached 51 years in 2007; 12.3 is the number of years in the current practice; and most prosthodontists (71%) are solo private practitioners. The average amount of time per week by prosthodontists in the practice averaged 36.1 hours, and prosthodontists treated an average of 44.1 patient visits per week. The largest source of patient referrals is the patient themselves. The largest percentage of a prosthodontist's treatment time is spent rendering procedures in fixed prosthodontics, but this percentage has declined since 2001. In 2007, the average gross billings of a practicing prosthodontist reached $805,675; average total practice expenses were $518,255; the mean net earnings of practitioners were $268,930. CONCLUSION: In 2007, prosthodontists in private practice paid out about $1.4 billion in practice expenses to provide $2.2 billion dollars in prosthodontic care. Based on survey results from 2007 and the previous 6 years, specialization in prosthodontic care continues to be an economically attractive and productive healthcare profession in the United States.

The work is fulfilled on the basis of research 330 persons age from 14 till 70 years from a common population of Tbilisi. Phylum of research - case - control of Criterion of incorporation: the patients entered clinic per 2005-2009, Criterion of exception: general diseases, Diabetes, autoimmune diseases, serious forms parodontosis, called by somatopathies. Statistical Analysis spent with the help of the package of statistical programs SPSS 11.5 Is placed, that the relative chance of need veneers is defined by the following factors: smoking - OR=1.82 (95%CI=1.13-12.37); pathologies gastrointestinal of a path - OR=1.94 (95%CI=1.22-14.26); the locuses of a focal infection contamination - OR=65.57 (95%CI=8.80-76.22); the mechanical factor - OR=2.23 (95%CI=1.27-58.95); medicamental treatment - OR=2.14 (95%CI1.34-24.56); feeding mainly by carbohydrates - OR=2.89 (95%C=I.51-13.15); the often use sweet - OR=1.87 (95%CI=1.07-9.85); often use of coffee OR=1.75 (95%CI=1.10-12.51); distal an occlusion - OR =2.26 (95%CI=1.09-18.68); - subcompensated caries - OR=2.04 (95%CI1.28-23.48); a ulitis - OR=1.62 (95%CI1.02-19.20); complications after previous veneer: particulate or complete chip of a seal - OR=34.12 (95%CI7.98-52.11); discoloration a seal - OR=80.67 (95%CI19.15-509.48); appearance line of demarcation - OR=95.23 (95%CI12.86-714.61); recurrent a caries - OR=25.75 (95%CI=7.69-39.87); Ulitis - OR=11.22 (95%CI=3.22-68.99); exhibitings of a pathological microflora - OR=123.16 (95%CI=16.68-726.40).

[Correlations complications after cosmetic veneer treatment with initial parameters of oral cavity].

The aim of the study was to define interrelations between complications after veneer treatment with initial parameters of an oral cavity, state of an organism, social and biological factors. 65 patients with veneers treated between 2005 and 2009 at Margvelashvili Dental Clinic (Tbilisi) were investigated. Correlation analysis on Spearmen was spent with application of the package statistical programs SPSS 11.5. Chip of veneers finds out significant positive correlation with the following factors: a crossbite - r=0.2543, p<0.0409; decompensative caries - r=0.3189, p<0.0096; exhibiting of a pathological microflora - r=0.2879, p<0.0163; discoloration - patient with age 41-60 y. - r=0.3877, p<0.0014; focal infection contamination - r=0.2599, p<0.0366; often use of coffee - r=0.2819, p<0.0229; ulitis up to veneer - r=0.2444, p<0.0498; appearance line of demarcation - with the mechanical factor - r=0.3479, p<0.0045; use of synthetic fluids, - r=0.3823, p<0.0017; recurrence caries - with gastro-intestinal pathologies r=0.2924, p<0.0181; of a focal infection contamination - r=0.2756, p<0.0263; by feeding priority by carbohydrates - r=0.2324, p<0.0625; decompensate caries - r=0.2583, p<0.0377; Exhibiting of a pathological microflora - among males - r=0.2772, p<0.0254; by smoking - r=0.3227, p<0.0087; gastro-intestinal pathologies - r=0.2365, p<0.0579; by endocrine diseases - r=0.2546, p<0.0407; by focal infection contamination - r=0.5416, p<0.0000; decompensate caries - r= 0.2530, p<0.0420; by an ulitis - r=0.4551, p<0.0001; by a hygienic index - r=0.4611; p<0.0001; periodontal index - r=0.4611, p<0.0001; PMA index - r=0.3529, p<0.0039. The correlation circuit of the factors of complications after veneers will help the practical stomatologists with realization of purposeful prophylaxis.
