A Survey: How Periodontists and Other Dental Professionals View the Scope of Periodontics

Background : How do periodontists think of themselves when they define their practices? How do other dental professionals view the scope of the specialty of periodontology? A strong component of periodontal residency programs is extracting teeth and preserving or building bony ridges for the eventual placement of implants. Has the discipline of periodontology moved away from retaining and treating the natural dentition? By the use of a rank‐order survey, the practice of periodontology was defined by periodontists and other dental professionals. Methods: In a pilot study, respondents were asked to list the answers to the question, “What is a periodontist?” The results were consolidated into eight statements. The eight statements were placed into an anonymous rank‐order survey, and more than 1,200 responses were returned. The responses primarily came from periodontists, hygienists, general practitioners, dental students, and dental hygiene students. Results: “Periodontists surgically treat advanced gum and bone infection problems” was considered the most important statement in all of the cohorts. The least important statement considered by all was, “Periodontists are educators promoting health.” Non‐periodontist dentists (NPDs) ranked the statement, “Periodontists perform dental implants and related procedures” less importantly (P <0.001) than the periodontists. The non‐periodontist cohort (NPC), which includes NPDs and dental hygienists, ranked the statement, “Periodontists’ treatments help general dentists and other specialists increase successful therapeutic outcomes” as second most important. Conclusions: The results of this survey indicate that periodontists ranked the placement of implants and their related procedures higher than the NPC. NPDs appear to value periodontists in treating the natural dentition for their patients. The NPC appreciates that periodontal therapy done by periodontists increases their therapeutic success for their patients.     

Factors influencing the diagnosis and treatment of periodontal disease by dental practitioners in Victoria

BACKGROUND: Healthy periodontal tissues are essential to overall dental health. Therefore, the detection and management of periodontal disease is an integral part of general dental practice. The aim of this study was to investigate confidence in diagnosis and management of periodontal disease by general dental practitioners (GDPs), assess if the Dental Practice Board guidelines on periodontal record keeping are being addressed, and, if necessary, try to find ways of improving the periodontal knowledge of GDPs. METHODS: A survey assessing practitioner confidence in diagnosing and treating periodontal disease was sent to a random selection of 550 dental care providers registered with the Dental Practice Board of Victoria. RESULTS: Two hundred and eighty five (51.8 per cent) of questionnaires were returned completed. It was found that 79.7 per cent of the sampled population screened all new patients for periodontal disease. The majority of respondents felt confident to diagnose and treat gingivitis and initial periodontitis. However, only 61.9 per cent felt confident to diagnose aggressive/early onset periodontitis, and many were not confident in treating advanced periodontitis (36.3 per cent) or aggressive periodontitis (51.6 per cent). The majority of dentists reported that they provided most of the non surgical periodontal therapy to their patients, while most surgical treatments were referred to specialist periodontists. Factors deemed to be important in influencing the decision to provide periodontal treatment included level of training and ability to motivate patients to improve oral hygiene. Many responents requested periodontic continuing education (CE) courses be run. CONCLUSIONS: Most of the dentists surveyed were confident to diagnose periodontal disease and to treat the more common presentations of periodontal disease. There is some evidence to suggest that some practitioners are not following the minimum requirements set by the Dental Practice Board of Victoria in relation to periodontal record keeping. The results also indicate a need for more periodontic CE courses in Victoria.     

Quo vadis: what is the future of periodontics? How will we get there?

Approximately 40 years ago periodontists began systematically developing the evidence to treat predictably and prevent gingivitis and periodontitis. More recently, periodontists have been among a small group of skilled dental‐implant surgeons leading that revolution in dentistry. Today, much of the mild/localized moderate periodontitis is not treated by periodontists, and an increasing number of implants are placed by dentists with limited surgical training. The current field of periodontics includes a broad range of surgical skills and technologies to regenerate predictably destroyed tissues and manage complex interdisciplinary treatment that may, in some way, involve the tissues that support teeth and implants. In addition, periodontal researchers have shown that moderate‐to‐severe periodontitis increases the systemic inflammatory burden and transient bacteremias that result in a significant independent role for periodontitis in multiple systemic diseases. Although many periodontists have very advanced practices that incorporate certain aspects of the current and near‐future dimensions of periodontics, the innovations and technologies have not yet fully integrated throughout the specialty. It is an appropriate time to ask the question: Quo vadis? Which paths have the potential to deliver great value to our patients and to the health‐care system? And who will be our patients in the near future? We propose some key capabilities, knowledge and clinical applications. Perhaps most importantly, we propose new partnerships. Much of the vision centers around the application of special diagnostic technologies and surgical skills to help our dental colleagues better manage complex dental and periodontal cases and to deliver on the promise of reducing systemic inflammation sufficiently to enhance medical management of certain chronic diseases and reduce preterm births. The specialty has always been about retaining teeth in good health and in recent years has focused on controlling oral inflammation to enhance systemic health. We already have several of the key principles, concepts and technologies that are likely to define the role of periodontics in the evolving health‐care delivery system. Perhaps it is time to define the mission and start moving toward the future periodontics.     

Communicating with each other

Most dentists commit their professional lives to improving oral health by providing preventive and treatment services to their patients. In addition, dentists often participate in community, professional or legal activities that promote oral health. This paper describes five ways that dentists have worked with each other and with others to enhance oral health: (1) Dentists working with each other to promote oral health without the use of organized dentistry. Described as an example is the experience of all the periodontists in one city in the USA in providing community education. (2) Dental associations organizing or facilitating groups of dentists and other dental health professionals to develop and implement programmes that promote oral health. Two community-based educational efforts stimulated by the American Dental Association are described. (3) Dental specialty associations encouraging and facilitating specialists to work with other dentists to enhance their knowledge and skills in prevention, treatment and appropriate referral. The American Academy of Periodontology's efforts to teach communication skills to periodontists and diagnosis and treatment skills to general practitioners is cited as an example. (4) Dentists working with physicians and other non-dental health professionals to promote oral health. Integrating dental education into childbirth preparation classes for expectant parents is one instance of an interdisciplinary approach. (5) An individual dentist taking a leadership role to positively influence legislation to regulate a harmful substance. The efforts of one dentist to restrict the sale and promotion of smokeless tobacco are described. Working with other dentists, health care providers and legislators represent alternative ways that dentists have affected the oral health of individuals.     

Comparative Analysis of User‐Generated Online Yelp Reviews for Periodontal Practices in Multiple Metropolitan Markets

Background: Previously published research for a single metropolitan market (Austin, Texas) found that periodontists fare poorly on the Yelp website for nearly all measured metrics, including average star ratings, number of reviews, review removal rate, and evaluations by “elite” Yelp users. The purpose of the current study is to confirm or refute these findings by expanding datasets to additional metropolitan markets of various sizes and geographic locations. Methods: A total of 6,559 Yelp reviews were examined for general dentists, endodontists, pediatric dentists, oral surgeons, orthodontists, and periodontists in small (Austin, Texas), medium (Seattle, Washington), and large (New York City, New York) metropolitan markets. Numerous review characteristics were evaluated, including: 1) total number of reviews; 2) average star rating; 3) review filtering rate; and 4) number of reviews by Yelp members with elite status. Results were compared in multiple ways to determine whether statistically significant differences existed. Results: In all metropolitan markets, periodontists were outperformed by all other dental specialties for all measured Yelp metrics in this study. Intermetropolitan comparisons of periodontal practices showed no statistically significant differences. Conclusions: Periodontists were outperformed consistently by all other dental specialties in every measured metric on the Yelp website. These results were consistent and repeated in all three metropolitan markets evaluated in this study. Poor performance of periodontists on Yelp may be related to the age profile of patients in the typical periodontal practice. This may result in inadvertently biased filtering of periodontal reviews and subsequently poor performance in multiple other categories.     

An analysis examining socio-economic variations in the provision of NHS general dental practitioner care under a fee for service contract among adolescents: Northern Ireland Longitudinal Study

Telford C, Murray L, Donaldson M, O’Neill C. An analysis examining socio‐economic variations in the provision of NHS general dental practitioner care under a fee for service contract among adolescents: Northern Ireland Longitudinal Study. Community Dent Oral Epidemiol 2012; 40: 70–79. © 2011 John Wiley & Sons A/S Abstract – Objectives: To examine socio‐economic variations in the use of publicly funded general dental practitioner care by adolescents under a fee for service arrangement. Method: Publicly funded general practitioner reimbursement data were linked to census and vital statistics data within the Northern Ireland Longitudinal Study. Data relate to 12 846 adolescents aged 11 or 12 in April 2003 included within the Northern Ireland Longitudinal Study (28% of the population). The main outcome measure was consumption of dental care between 2003/2004 and 2007/2008 by socio‐economic status (as measured by National Statistics Socio‐economic Classification of occupation and highest educational attainment of household reference person). Results: In multivariate analysis, socio‐economic status was a significant determinant of dental care consumed. Those of the lowest socio‐economic status, according to both occupation and highest educational attainment of household reference person, were less likely to have consumed orthodontics OR 0.76 (0.62, 0.95) and OR 0.79 (0.69, 0.91), respectively. Those of lower socio‐economic status were, however, more likely to have undergone an extraction and restorative treatment and also consumed on average more treatment than those of higher socio‐economic status. Conclusion: A demand‐led service, in which practitioners are reimbursed in part on a fee for service basis, may create incentives that contribute to different patterns of utilization between social groups. Such a system may not be providing equal access for equal need and may widen existing socio‐economic disparities in oral health among adolescents.     

A comparison of diagnostic screening data derived from general dental practitioners and periodontists used for initial treatment planning in periodontitis patients

As the quality of clinical information contained in referral letters for specialist care may determine the initial decisions as to appropriate treatment for patients, it is important that this information is objective and accurate. The use of a standardised questionnaire for this purpose improves the quality of information received, but it is not known how accurate this information is if used in the decision-making process for treatment planning. The aim of this study was to compare the clinical assessment data derived from a standardised questionnaire used by referring patients to a specialist periodontal unit. Equivalent data recorded by dentists and periodontists were compared to establish whether the data were consistently reproducible, and therefore usable for deciding on the appropriate initial phase of treatment for patients. Data from 50 patients referred for periodontal treatment planning and specialist care in which the questionnaires from the general dental practitioner and the subsequent periodontal assessment were available were compared. All of the patients were medically healthy and were not taking any long-term medication. The patients were selected based on the retrospective availability of equivalent clinical data from the questionnaires and consultation in the periodontal department at the Eastman Dental Hospital, London. The equivalence or disparity in the identification of different cofactors, and the community periodontal index of treatment need (CPITN) (basic periodontal examination, BPE) scores recorded by referring dentists (GDP), and periodontists (EDH, Eastman Dental Hospital) were annotated and compared. A level of equivalence of over 50% of assessments was demonstrated between referring dentists and periodontists in the variables of oral hygiene, smoking, bleeding on probing and restorative factors, as well as in the recorded scores of the CPITN (BPE) screening system. It can be concluded that the use of questionnaires for referral for specialist services is useful to not only improve and standardise the quality and extent of the relevant clinical information received, but may also be a valuable resource that may be used in the initial decision-making process for screening patients to the appropriate level of periodontal care. However, the limitations of this observational study preclude drawing any definitive conclusions in the absence of a more carefully controlled study designed specifically to overcome these limitations.     

Preferences of dental care providers in maintaining compromised teeth in relation to their professional status: implants instead of periodontally involved maxillary molars?

Aim: The purpose of this study was to evaluate the dentists' decision making in the maxillary molar region to find out how it is influenced by general practitioners' and specialists' characteristics as well as by the external evidence. Material and methods: A questionnaire was developed containing clinical cases and statements to assess practitioners' opinions on the treatment of periodontally involved maxillary molars and implant therapy with sinus grafting. Data were analysed with respect to the dentists' age and speciality. Results: Three hundred and forty questionnaires were evaluated (24% from universities, 76% from educational courses, overall response rate 35.1%). Forty six per cent of all participants indicated they had specialised, 52% placed dental implants, while 33% performed sinus grafting and 64% periodontal surgeries. Forty six per cent were against or were indecisive about having sinus grafting performed on themselves. The treatment proposals given for the clinical cases revealed a preference among older dentists and general practitioners for regenerative treatments even when these were not evidence based in through‐and‐through furcation involvements. Resective therapies were most often selected by periodontists. Prosthodontists tended to prefer more invasive treatment options with extractions and augmentations. More experienced general practitioners favoured conventional fixed dental prostheses in free‐end situations or no treatment rather than the complicated augmentation procedures, which were preferred by younger dentists. Conclusions: Implant placement seems to be widely accepted by almost all subjects, who may either place implants themselves or refer patients. More information seems to be needed on the indications for regenerative therapies for furcation involved maxillary molars, and guidelines required for decision making in complex clinical situations.

A practical approach to the diagnosis and treatment of periodontal disease

BACKGROUND: Both nonsurgical and surgical periodontal therapies are important in the control of most forms of periodontal disease. Sometimes, nonsurgical therapy is adequate to control the disease in mild cases and to slow progression and maintain periodontal stability in more advanced cases. Other times, both therapies may be indicated to obtain satisfactory results. The author presents treatment guidelines and recommendations for periodontal therapy. METHODS: The author searched the dental literature for information pertaining to periodontal therapy. RESULTS: The author found evidence-based data to support the effectiveness of nonsurgical and surgical periodontal therapy in controlling periodontal disease. Nonsurgical periodontal therapy requires time, effort, and good diagnostic and clinical skills to obtain satisfactory results. The results are determined by evaluating the patient's periodontal disease after active therapy, at which time additional surgical or nonsurgical treatment may be recommended. Evaluation should continue throughout the lifelong supportive phase of periodontal therapy. CONCLUSION: Clinicians should continue to develop and enhance their diagnostic skills, assess factors that affect diagnosis and prognosis, formulate a comprehensive treatment plan, render appropriate treatment, evaluate the outcome and determine when periodontal care is indicated. CLINICAL IMPLICATION: Failure to comply with monitoring the patient's periodontal status may lead to uncontrolled disease and eventually premature tooth loss. Premature tooth loss can be prevented through patient education and application of evidence-based nonsurgical and surgical therapy.     

Foreign service special care opportunity in SCDA

A foreign service clinic in Guatemala caring for patients with special needs was initiated by joining SCDA efforts with the Open Wide Foundation. The trip included five SCDA members: two AEGD residents and three support staff. Open Wide participants included the Executive Director, the Clinical Director in Guatemala, as well as two dentists, dental support staff, and Guatemalan dental students. Two physician anesthesiologists provided general anesthesia. Care adjuncts included general anesthesia, oral sedation, and medical stabilization. Lessons learned: (1) Conducting a dental clinic for patients with special needs is possible and relatively easy to accomplish, given a partnership with a foundation that agrees with and facilitates this service; (2) advance planning is required to maximize the service provided; (3) committed and flexible team members can accomplish a significant amount of care in a short period of time; and (4) limited but invaluable training of in‐country healthcare providers is possible. The Special Care Dentistry Association is long known for service and care delivery to patients with special needs by its members, and for its advocacy and organizational support for these activities. A foreign service opportunity in Guatemala, Central America, was sought out by members of the SCDA to further the outreach efforts of the organization, give members clinical experience in a foreign setting, and train in‐country providers to deliver care to patients with special needs. This was the first effort by SCDA members to host a clinic to deliver care specifically to patients with special needs outside of North America.     

Epidemiological evaluation of the outcomes of nonsurgical root canal treatment in a large cohort of insured dental patients.

Selected outcomes following initial nonsurgical root canal treatment (NSRCT) procedures were retrospectively assessed using an insurance company database of 110,766 nonsurgical root canal procedures that were completed by endodontists and their referring general dentists. A subset of 44,613 cases, with a minimum required follow-up time of 2 yr, showed incidences of extraction, retreatment and periradicular surgery equal to 5.56%, 2.47%, and 1.41%, respectively. The incidence of subsequent extraction increased with patient age. Teeth that were not restored after root canal therapy were significantly more likely to undergo extraction than restored teeth. Although the practice pattern for endodontists consisted of a significantly higher proportion of molars (48% more; p < 0.001) and a smaller proportion of anterior teeth (43% less; p < 0.001) than general dentists, both groups of providers had comparable rates of untoward events. These data strongly support the hypothesis that the specialist practice provides similar rates of clinical success compared with other providers, even when treating significantly more complex NSRCT cases. Overall, 94.44% of nonsurgical root canal treated teeth remained functional over an average follow-up time of 3.5 yr. These results are an important indication of the benefits of endodontic treatment when provided in an integrated health care delivery system of endodontists and their referring general dentists.     

Use of dental services: an analysis of visits, procedures and providers, 1996

BACKGROUND: While many studies have provided data on Americans' access to dental care, few have provided a detailed understanding of what specific treatments patients receive. This article provides detailed information about the types of dental services that Americans receive and the types of providers who render them. METHODS: The authors provide national estimates for the U.S. civilian noninstitutionalized population in several socioeconomic and demographic categories regarding dental visits, procedures performed and the types of providers who performed them, using household data from the 1996 Medical Expenditure Panel Survey, or MEPS. RESULTS: Data show that while the combination of diagnostic and preventive services adds up to 65 percent of all dental procedures, the combination of periodontal and endodontic procedures represents only 3 percent. Additionally, while 81 percent of all dental visits were reported as visits to general dentists, approximately 7 percent and 5 percent of respondents who had had a dental visit reported having visited orthodontists or oral surgeons, respectively. CONCLUSION: MEPS data show the magnitude and nature of dental visits in aggregate and for each of several demographic and socioeconomic categories. This information establishes a nationally representative baseline for the U.S. population in terms of rates of utilization, number and types of procedures and variations in types of providers performing the procedures. These nationally representative estimates include data elements that describe specific dental visits, dental procedures and type of provider, and they offer details that are useful, important and not found elsewhere. PRACTICE IMPLICATIONS: By understanding these analyses, U.S. dentists will be better positioned to provide care and better meet the dental care needs of all Americans.     

Periodontal management of patients with cardiovascular diseases

Periodontists are often called upon to provide periodontal therapy for patients with a variety of cardiovascular diseases. Safe and effective periodontal treatment requires a general understanding of the underlying cardiovascular diseases, their medical management, and necessary modifications to dental/periodontal therapy that may be required. In this informational paper more common cardiovascular disorders will be discussed and dental management considerations briefly described. This paper is intended for the use of periodontists and members of the dental profession.     

PRENATAL DENTAL CARE: EVALUATION OF PROFESSIONAL KNOWLEDGE OF OBSTETRICIANS AND DENTISTS IN THE CITIES OF LONDRINA/PR AND BAURU/SP,BRAZIL, 2004

The purpose of this study was to assess the current knowledge and recommendations of obstetricians and dentists as to the dental care to pregnant patients in the cities of Londrina/PR and Bauru/SP, Brazil. Questionnaires were distributed to professionals of both cities, arguing on the following issues: oral health during pregnancy; contact between prenatal care and dental care providers; prenatal fluoride supplementation; selection of therapeutic agents for local anesthesia, pain control and treatment of infection; and dental procedures that can be performed during each trimester. Data were analyzed by frequency of responses and statistical analyses were carried out using X² (type of workplace/service) and t test (time since graduation), significant if p<0.05. Seventy-nine obstetricians and 37 dentists responded the questionnaires. Most physicians referred the patient to dental care only when a source of dental problem was mentioned, limiting the adoption of a preventive approach. Forty-three percent of dentists and 34% of obstetricians did not know the potential contribution of periodontal infection as a risk factor for preterm low birth-weight babies. There was divergence from scientific literature as to the recommendation of local anesthetics (dentists and obstetricians), prenatal fluoride supplementation (obstetricians) and dental radiographs (dentists). The findings of this survey with dentists and obstetricians showed that dental management during pregnancy still presents some deviations from scientific literature recommendations, indicating the need to update these health care professionals in order to establish guidelines for prenatal dental care.     

Periodontal treatment for elderly patients

The largest growing segment of our society is that of older adults. The population explosion of older adults challenges both general practitioners and periodontists to provide the highest level of care available. More of our patients will have concurrent medical conditions that alter or modify the delivery and provision of periodontal care. This paper reviews some of the common conditions occurring in the older patient and suggests some modifications in periodontal therapy which may be beneficial. The therapist must be knowledgeable about the medications commonly used for treating the chronic diseases of the older population. Finally, the therapist must become adept in performing functional assessments of patients so that the types of therapy administered contribute to the quality of life desired by patients.

Patterns of oral care in dental school and general dental practice

This study compared patterns of oral care provided by predoctoral dental students for patients seeking treatment at the University of Washington (UW) with patterns reported for general dental offices by the Washington Dental Service (WDS). Dental care included about 5 million services provided to 880,317 patients by 2,803 WDS general dentists and about 45,600 dental services provided to 9,488 patients by 155 UW dental students during 1999. There was high fidelity between databases and randomly surveyed patient records for treatment provided in both UW (95 percent) and WDS (97 percent) populations. While patient age patterns were generally similar, UW students completed more procedures for young children and for adults older than seventy-four years but completed fewer procedures for age groups of from thirteen to eighteen and from forty-five to fifty-four than general dental offices. The relative mix of all services completed by UW and WDS providers was similar (ANOVA, P=0.82). Within categories of service, the percentage of total services completed by students compared to those submitted by community dentists to WDS was about the same for examinations, radiographs, fluoride and sealants, amalgams, composites, single crowns, and endodontics. The percentage of total procedures completed showed a greater emphasis by UW students on inlays/onlays, dentures, extractions, and periodontal maintenance, and lesser experience with implants, orthodontics, sedation, and emergency procedures than general dental offices. We conclude that the relative distribution of clinical services provided by UW dental students is comparable to those procedures reported to WDS by dental offices in the adjacent community.     

Influences of market competition on dental care utilization under the global budget payment system

Objectives: The degrees of market competition usually influence providers’ behaviors. This study investigated the influence of medical market competition on the utilization of dental care under the global budget payment system. This study also examined the relative factors that influence the utilization of dental care. Methods: This study used the healthcare sub‐regions (HCSRs) in the healthcare net as the observation units. The dataset was the National Health Insurance dental care claim data from 1999 to 2002. The degree of market competition of dental care was measured by the Herfindahl Index (HI). The influences of medical market competition on the utilization of dental care were analyzed by multiple linear regression analysis. Results: When the market had a higher degree of competition, people had a higher number of dental utilizations after controlling for the other variables. When market competition increased by 1%, annual expenditures and frequencies of dental care as well as frequencies of tooth‐filling per person increased by 0.4%. Thirty‐three percent of dental expenditures could be explained by increases in the degree of market competition. Females or highly educated people had a positive correlation with dental utilization. However, the agricultural population negatively correlated with dental utilization. Average household income had no significant relationship with the frequency of dental care but had a significant negative association with dental expenditures when dental care was covered by health insurance. Conclusions: After the global budget payment system for dental care was implemented, increases in dental care market competition led to the increase in utilization of dental care services.
