Turning an idea into a PEARL study

Overview

A typical PEARL study may last anywhere from one month to three years. Most are short-term observational studies that compare the effectiveness of diagnostic procedures, treatments, or materials; evaluate risk factors associated with particular treatments; or assess dentists' and/or patients' expectations of outcomes. All PEARL studies relate to the day-to-day clinical needs of private dentists and their patients by addressing a fundamental clinical question: Why we do what we do, and how can we do it better? All PEARL studies begin with an idea submitted by a PEARL Practitioner-Investigator: see Turning an idea into a PEARL study further down on this page. Once a study is completed, results are posted on a secure website where participating dentists can compare their outcomes with those of other Network members

Current PEARL studies

The following PEARL studies are now under way and/or accruing practices:

Treatment of Deep Caries (PRL0604)
Dentists are frequently faced with the decision of whether to remove all carious dentin and risk pulpal exposure or to leave carious dentin in close proximity to the pulp and seal the lesion with a resin-bonded restoration during the excavation of a deep carious lesion.  To address this question, this study compares the effect of complete versus partial caries removal in class I and II deep carious lesions on (1) pulp vitality, (2) post-operative hypersensitivity and quality of life, and (3) the type of lining and bonding technique outcomes.

Implant Outcomes (PRL1012)
Periodontally compromised teeth or teeth with endodontic treatment failure are often replaced with an implant supported restoration.  Often the option of implant therapy is compared with the prognosis and cost of endodontic therapy.  Most recent survival studies on implants have reported success rates of greater than 95% for 5 to 10 years with almost all studies being conducted in University or specialist practices. However, few studies have been conducted concerning the relative success of implant treatment and restoration in general practice settings. The objective of the implant outcomes study is to evaluate the 3-5 year outcome of implant supported restorations and the factors associated with success or failure within general practice settings.  The implant study, together with endodontic treatment outcomes study, will provide practitioners with a basis with which to provide patients with a data based treatment outcome of implant versus endodontic treatment.

Post-Operative Hypersensitivity:  Randomized Comparative Effectiveness Research Trial (PRL1013)
Results of the PEARL study, “Post-operative hypersensitivity after placement of Class I bonded resin based composite restorations”, found that hypersensitivity was common after placement of this restoration but raised the questions as to whether placement of a liner was an effective means to decrease sensitivity.  This lead to our development of this two-armed, randomized clinical trial is to compare the effect on post-operative hypersensitivity of resin-bonded composite restorations using a dentin bonding agent, with and without placement of a resin modified glass ionomer liner.  The reduction in hypersensitivity between the 2 groups will be compared clinically using air and cold testing and by patient reported outcomes at three time points: prior to placement of the restoration and 1 and 4 week s post-operatively.  In addition, potential risk factors for post-operative hypersensitivity will be recorded including:  stage/extent of the carious lesion as measured by the proposed ADA Caries Classification System, lesion depth as measured on the preoperative radiograph, dentin caries ranked on opening the lesion, preparation depth, and patient sleep bruxism status.

Completed PEARL studies

The following PEARL studies have been completed:

Deep Caries Treatment Survey (PRL0501)
A survey of the PEARL membership was conducted to determine preferred treatment approach for deep carious lesions and whether it was influenced by the practitioner’s expectations for pulpal exposure. Survey findings indicated that approximately 20% of PEARL Network dentists favored partial caries removal techniques. Given the various treatments employed, it was determined that a deep caries treatment outcome study was warranted, and thus this study’s results led directly to the PEARL study “Complete vs. Partial Removal of Deep Caries” (see above). The study's findings were published in the Journal of General Dentistry (see Oen et al., "Attitudes and Expectations...," 2007, below).

Postoperative Hypersensitivity in Occlusal Restorations (PRL0602)
This study was conducted to (1) determine the incidence and severity of POH as reported by patients who receive Class I RBC restorations; (2) measure the associations between POH and restoration width and depth, dentin caries activity, lining and bonding materials, and restorative materials and techniques; and (3) assess RBC restoration treatment and its impacts on oral health–related quality of life as reported by patients. Preliminary findings of this study were published in the July/August 2009 issue of Compendium of Continuing Education in Dentistry (see Berkowitz et al., “Postoperative hypersensitivity...,”2009, below).

Osteonecrosis of the Jaw (PRL0603)
Osteonecrosis of the jaw (ONJ) is a severe disease of bone that affects both the maxilla and mandible and is characterized by the intraoral exposure of bone and sequestrum formation.  Its cause is unknown but an increased incidence of ONJ has been associated with bisphosphonates, used in the treatment of osteoporosis, hypercalcemia of malignancy, and Paget’s disease.  The objective of this case control study is to determine the profile of factors, including bisphosphonate usage, that are predictive of ONJ.

Endodontic Treatment Outcomes (PRL0705)
The majority of endodontic therapy occurs in general practice settings; however, most studies on endodontic success rates have been conducted in specialty practices or in academic centers. Since the general dentist is frequently faced with the question of whether extraction and placement of a dental implant has a better long-term prognosis than conventional endodontic therapy, this study will determine the three- and five-year outcomes and risk factors associated with success and failure of endodontically-treated teeth in general dental practices.  This study defines failure from the patient’s perspective; i.e. any additional cost associated with the root canal and/or restorative procedure.

Analgesic use and effectiveness (PRL0706)
The dental profession has an ever-growing number of analgesics to prescribe or recommend for the management of pain. However, the most effective analgesic for a particular procedure or patient is often not clear. To address this issue, this study will determine (1) the degree of pain that a dentist perceives a procedure will produce and his /her prescription or recommendation to control the pain, and (2) the patient’s perception of how well the medication controlled the pain.

Treatment of Non-carious Cervical Lesions (PRL0707)
The treatment of hypersensitive non-carious cervical lesions (NCLs) remains controversial and few studies have compared the effectiveness of various treatments or their financial implications. The objective of this three-armed, randomized clinical trial is to compare treatment efficacy over a 6-month period, making this the longest study of its kind of three commonly used treatments for hypersensitive NCLs: (1) a chemoactive dentifrice, (2) a dentin bonding agent with sealant and, (3) a flowable resin-based composite restoration. The primary outcome objective is the reduction in hypersensitivity as measured by the patient. However, the study will also evaluate dentin tubule occlusion, retention of resin coatings, retention of restorations and lesion size by scanning electron microscopy examination of intraoral replicas of pre- and post-treatment NCL surfaces. Therefore, by study’s end, PEARL will be able to combine objective clinical assessments of the three NCL treatments with laboratory assessments of dentin tubule occlusion and lesion size.

Periodontal Diagnosis and Referral (PRL0808)
Completed in 2010, this study was designed to determine the criteria used to establish a periodontal diagnosis, the types of periodontal therapy provided, and who provides periodontal therapy in PEARL Network general dental practices.  A unique feature of the study was the “randomized clinical presentation” design, administered through the “Members Only” section of the PEARL website.  PEARL practitioner-investigators who maintain a general practice were randomly presented with 5 clinical scenarios that represent the range of periodontal health, gingivitis, and mild, moderate and severe periodontitis.  The practitioner-investigator was asked how she/he would examine, diagnose, and treat the patient described in the scenario in his/her own practice.  The study also sought to determine the criteria used to triage periodontal patients among the dentist, dental hygienist, and specialist and the use of adjuncts such as chemotherapeutics within the Network.

Survey to Assess the Impact of Dental Practice-Based Research Networks on Patient Care (PRL0809)
This trans-PBRN study will assess the impact of practice-based dental research on Network practices and on dentistry in general. A questionnaire is being administered to Practitioner-Investigators in the three NIDCR-funded Networks to determine whether and what changes have occurred in member practices. The questionnaire will be readministered annually as well as following the completion of studies and the publication of study results.

TMJD Pain (PRL0910)
Approximately 5-10% of the US population will seek care for painful temporomandibular muscle and joint disorders (TMJD) in their lifetime. General dentists are typically the first healthcare providers to see TMJD pain patients. However, there is no consensus regarding initial treatment for these problems. As a result, care varies from home-based self-care instruction with or without medications to use of mouth guards and other treatments. TMJD embraces a number of pains that involve the masticatory muscles, the temporomandibular joint, or both.  The objective of this survey is to learn more about the practitioner’s treatment habits with TMJD pain as well as to identify an interested group who would participate in a clinical study of TMJD.

Addictive Behavior Intervention (SBIRT)

The primary aim of this study is to assess the knowledge, attitudes, and beliefs of dentists regarding the provision of screening followed by treatment intervention and/or referral for 1) tobacco, 2) unhealthy alcohol use, and 3) illicit drug use.  The secondary aim is to identify practitioners who may be interested in participating in a future clinical trial of a dental practice-based substance use intervention.
