Abstract
UNLABELLED Internationally, a considerable proportion of children aged five years and younger require extraction of teeth due to dental caries and frequently dental general anaesthesia (DGA) is the treatment of choice. AIMS To investigate the records of a cohort of preschool children (aged five years and younger) referred to the public dental service provided at Cork University Hospital (CUH), Cork, Ireland, for extractions under DGA between the years 2000 and 2002. To determine the characteristics of the sample: disadvantage; the presence of a significant medical history; and, fluoride status. To establish the pattern of appointments and care, before, during and after DGA, and the pattern of dental treatment required up to sixth class (aged 11 to 12 years). METHODS A retrospective review of dental records of a cohort of preschool-aged children referred for DGA in CUH during the years 2000-2002 was completed. Demographic and clinical data were collated and analysed using Statistical Packages for Social Sciences (SPSS). Costs were provided by CUH and the Health Service Executive (HSE). Data on costs relating to preventive programmes were obtained from information presented in the Irish Oral Health Services Guideline Initiative 2009. RESULTS A total of 347 children were included with a median age of.fQur years and a range of one to five years. Children with a disadvantage were more likely to require extractions under DGA than their- counterparts (50%, n=175). In total, 73% (n=253)~ of patients had a fluoridated water supply and 91% (n=316) had no adverse medical history. For 88% (n=306), their first dental visit was an emergency appointment. The primary indication for DGA was treatment of dental caries. A recall appointment was provided for 18% (n=63). One-quarter (n=86) required an extraction, antibiotic or referral for a second DGA at their first visit following DGA. In first class, referral for a second DGA or extraction under local anaesthetic (LA) was required for 23% (n=79) of patients. Over 60% (n=21 1) required either an extraction or a restoration in third class. In excess of 20% (n=69) of patients did not attend the sixth class dental inspection, the final assessment appointment in the public services. CONCLUSIONS A considerable number of preschool children require extractions under DGA due to dental caries. The results of this study indicate that such children progress to adolescence with poor oral health, as evidenced by the need for further restorations, extractions and repeat DGA. The average cost of DGA was E819 per child. This figure has been shown to be as much as eight times the cost of a preventive/oral health promotion prograrnme operating within a similar cohort. An integrated preventive programme targeting preschool-aged children should be considered in attempting to manage the hicih levels of dental caries within this age group.

Abstract
PURPOSE The purpose of this study was to perform a cost-benefit analysis of the age one dental visit for privately insured patients. METHODS A major insurance company provided claims from various states submitted between 2006-2012. Data provided included numbers of procedures and respective costs from the first visit until age six years. Data was organized into five groups based on age, for which the first D0145/D0150 code was submitted [(1) age younger than one year old; (2) age one or older but younger than two years old; (3) age two or older but younger than three years old; (4) age three or older but younger than four years old; and (5) age four or older but younger than five years old]. The ratio of procedures per child and average costs per child were calculated. RESULTS Claims for 94,574 children were analyzed; only one percent of these children had their first dental visit by age one. The annual cost for children who had their first dental visit by age one was significantly less than for children who waited until an older age. CONCLUSION There is an annual cost benefit in establishing a dental home by age one for privately insured patients.

Abstract
PURPOSE The purpose of this paper was to determine if number and cost of dental treatments in high caries-risk children differs in children with early dental intervention compared to children with later intervention. METHODS Billing data from children age zero to seven years old, whose first dental visit was between January 1, 2004 and December 31, 2004, were collected from 20 corporate treatment centers serving children from lower socioeconomic status backgrounds. Data included age at first visit, dental treatment codes, and associated costs for eight years after the first dental visit. Treatment included restorations, crowns, pulpotomies, and extractions. First visit age was categorized into early starters (younger than four years old) and late starters (four years of age or older). Linear regression with cluster adjustment for clinic determined a difference in costs and dental treatments by early and late starters. RESULTS Of 42,532 subjects, 17,040 (40 percent) were early starters and 25,492 (60 percent) were late starters. There were 3.58 more dental procedures performed on late starters, over eight years of follow-up, than on early starters (P<.001). Late starters spent $360 more over eight years of follow-up than early starters (P<.001). CONCLUSION In this study, number of procedures performed were fewer and cost of treatment less for children seen earlier versus later.

Economic modeling of sealing primary molars using a "value of information" approach. J Dent Res 2014; 93:876-81. [PMID: 25056993 PMCID: PMC4213251 DOI: 10.1177/0022034514544299] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2014] [Revised: 05/25/2014] [Accepted: 06/29/2014] [Indexed: 11/17/2022] Open
Abstract
The objective was to evaluate 2 primary molar sealant strategies for publicly insured children using an "expected value of perfect information" (EVPI) approach. We converted a 10,000-observation tooth-level cost-effectiveness simulation model comparing 2 primary molar sealant strategies - always seal (AS) and standard care (SC) - with a 1,250-observation child-level model. Costs per child per restoration or extraction averted were estimated. Opportunity losses under the AS strategy were determined for children for whom SC was the optimal choice. We determined the EVPI by multiplying mean opportunity losses by the projected incident population of publicly insured 3-year-olds in the US over 10 years with costs discounted at 2%. All analyses were conducted under assumptions of high and low intrachild correlations between at-risk teeth. The AS strategy cost $43.68 over SC (95% CI: -$5.50, $92.86) per child per restoration or extraction averted under the high intrachild correlation assumption and $15.54 (95% CI $7.86, $23.20) under the low intrachild correlation. Under high intrachild correlation, mean opportunity losses were $80.28 (95% CI: $76.39, $84.17) per child, and AS was the optimal strategy in 31% of children. Under low correlation, mean opportunity losses were $14.61 (95% CI: $12.20, $17.68) and AS was the optimal strategy in 87% of children. The EVPI was calculated at $530,813,740 and $96,578,389 (for high and low intrachild correlation, respectively), for a projected total incident population of 8,059,712 children. On average, always sealing primary molars is more effective than standard care, but widespread implementation of this preventive approach among publicly insured children would result in large opportunity losses. Additional research is needed to identify the subgroups of publicly insured children who would benefit the most from this effective and potentially cost-saving public health intervention.

Image and surgery-related costs comparing cone beam CT and panoramic imaging before removal of impacted mandibular third molars. Dentomaxillofac Radiol 2014; 43:20140001. [PMID: 24922557 PMCID: PMC4141671 DOI: 10.1259/dmfr.20140001] [Citation(s) in RCA: 32] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2014] [Revised: 06/08/2014] [Accepted: 06/11/2014] [Indexed: 11/05/2022] Open
Abstract
OBJECTIVES The aim of this prospective clinical study was to derive the absolute and relative costs of cone beam CT (CBCT) and panoramic imaging before removal of an impacted mandibular third molar. Furthermore, the study aimed to analyse the influence of different cost-setting scenarios on the outcome of the absolute and relative costs and the incremental costs related to surgery. METHODS A randomized clinical trial compared complications following surgical removal of a mandibular third molar, where the pre-operative diagnostic method had been panoramic imaging or CBCT. The resources implied in the two methods were measured with health economic tools. The primary outcome was total costs defined as the sum of absolute imaging costs and incremental surgery-related costs. The basic variables were capital costs, operational costs, radiological costs, radiographic costs, overheads and patient resource utilization. Differences in resources used for surgical and post-surgical management were calculated for each patient. RESULTS Converted to monetary units, the total costs for panoramic imaging equalized €49.29 and for CBCT examination €184.44. Modifying effects on this outcome such as differences in surgery time, treatment time for complications, pre- and post-surgical medication, sickness absence, specialist treatment and hospitalization were not statistically significant between the two diagnostic method groups. CONCLUSIONS Costs for a CBCT examination were approximately four times the costs for panoramic imaging when used prior to removal of a mandibular third molar. The use of CBCT did not change the resources used for surgery, post-surgical treatment and patient complication management.

What costs are associated with the management of third molars? J Oral Maxillofac Surg 2012; 70:S8-10.

Abstract
PURPOSE The purpose of this study was to estimate the treatment costs directly related to operative and nonoperative management of asymptomatic, disease-free, third molar (M3) teeth. MATERIALS AND METHODS The data reviewed were limited to claims submitted by oral and maxillofacial surgeons. The data collected included charges for consultations, radiographs, surgical removal of bony impacted teeth, and general anesthesia, using the 2009 data extracts from Delta Dental of Virginia. The median charges were used as a proxy for the actual costs attributable to the removal or retention of M3 teeth. Three clinical scenarios were executed using the available claims data to calculate the treatment costs associated with nonoperative and operative M3 management. An assumption made in the computation of expenses was that for subjects who elected to retain their M3s, the recommended management strategy was active surveillance. Active surveillance is a prescribed treatment to monitor the retained M3s characterized by performing a clinical examination and panoramic imaging every 2 years. The author assumed a 3% increase in charges per annum. RESULTS The 3 scenarios were as follows: scenario 1 (nonoperative management), retention of asymptomatic, disease-free M3s and monitoring for 20 years from age 18 to 38 years; scenario 2 (operative management), removal of 2 asymptomatic, disease-free, bony impacted M3s for 18-year-old patients using general anesthesia (30 minutes) in an office-based ambulatory setting; and scenario 3 (failure of non-operative management), removal of 1 previously asymptomatic, disease-free, bony impacted M3 after 10 years of follow-up in a now 28-year-old patient using general anesthesia (30 minutes) in an office-based ambulatory setting. The estimated charges for managing M3s were $2,342, $1,184, and $1,997 for scenarios 1, 2, and 3, respectively. CONCLUSIONS A simplified financial analysis derived from the dental claims data suggests that during the course of the patient's lifetime, the charges associated with non-operative management of asymptomatic, disease-free M3s will exceed the charges of operative management. The difference in costs might be important to patients when choosing between operative and non-operative management of their M3s.

Impact of dental therapists on productivity and finances: II. Federally Qualified Health Centers. J Dent Educ 2012; 76:1068-1076.

Abstract
This article estimates the impact of dental therapists treating children on Federally Qualified Health Center (FQHC) dental clinic finances and productivity. The analysis is based on twelve months of patient visit and financial data from large FQHC dental clinics (multiple delivery sites) in Connecticut and Wisconsin. Assuming dental therapists provide restorative, extraction, and pulpal services and dental hygienists continue to deliver all hygiene services, the maximum reduction in costs is about 6 percent. The limited impact of dental therapists on FQHC dental clinic finances is because 1) dental therapists only account for 17 percent of children services and 2) dentists are responsible for only 25 percent of clinic expenses and cost reductions are related to the difference between dental therapist and dentist wage rates.

Abstract
Occlusion and temporomandibular The issue of temporomandibular disorders (TMD) diagnosis and treatment has become a matter of increasing interest in the medical legal field in recent years. The old-fashioned theories based on the occlusal paradigm was proven to be erroneous, and clinicians who still provide irreversible treatments to TMD patients have to be conscious of the potential legal consequences of their behavior. The present paper described an illustrative case report of a patient to whom extensive and irreversible occlusal therapies were performed with the unique aim to provide relief from TMD symptoms. The treatment was unsuccessful and the dental practitioner was called into cause for a professional liability claim. The clinician was judged guilty of malpractice on the basis of the lack of scientific evidence of the irreversible occlusal approaches to TMD, which were erroneously used and did not give the patient any benefit, thus forcing him to a non necessary financial and biological cost. The failure to satisfy the contract with the patient, which is usually not covered by any insurance company, forced the practitioner to give the money back to the patient. The ethical and legal implications of such case were discussed, with particular focus on the concept that medical legal advices need to satisfy the highest standards of evidence and have to be strictly based on scientific knowledge.

Abstract
OBJECTIVE To investigate the response of dental practitioners to administration and remuneration adjustments to the Dental Treatment Services Scheme (DTSS) in the Republic of Ireland. DESIGN Following the introduction of a series of administration and fee adjustments by a third party payments system in December 1999 the pattern of extractions and restorations are examined to determine whether the adjustments had influenced provider behaviour, in particular whether a substitution effect from extractions to restorations would result from a relative fee increase of 62% for amalgam fillings. DATA AND METHODS Data on patient and provider characteristics from June 1996 to April 2005, collected by the Health Service Executive (HSE) National Shared Services Primary Care Reimbursement Service to facilitate remuneration to dentists providing services in the DTSS, was used in this analysis. A graphical analysis of the data revealed a structural break in the time-series and an apparent substitution to amalgam fillings following the introduction of the fee increases. To test the statistical significance of this break, the ratio of amalgams to restorations was regressed on the trend, growth and level dummy variables, using Ordinary Least Squares (OLS) regression. The diagnostics of the model were assessed using the Jarque-Bera normality test and the LM to test for serial correlation. RESULTS The initial results showed no evidence of a structural break. However on further investigation, when a pulse dummy was included to account for the immediate impact of the fee adjustment the results suggest a unit root process with a structural break in December 1999. This implies that the amalgam fee increase of December 1999 influenced the behaviour patterns of providers. CONCLUSIONS System changes can be used to change the emphasis from a scheme that was principally exodontia/emergency based to a scheme that is more conservative and based on restoration/prevention.

Abstract
REASONS FOR PERFORMING STUDY Extraction of cheek teeth (CT) by the conventional repulsion technique requires general anaesthesia and carries a high rate of post operative complications. Consequently, an alternative method of extraction, i.e. orally in standing horses, was evaluated. HYPOTHESIS The need for and risks of general anaesthesia could be avoided and post extraction sequelae reduced by performing extractions orally in standing horses. METHODS One hundred mainly younger horses (median age 8, range 2-18 years) with firmly attached CT that required extraction because of apical infections, displacements, diastemata, idiopathic fractures and the presence of supernumerary CT had the affected teeth (n = 111) extracted orally under standing sedation. Follow-up information was obtained for all cases, a median of 16 months later. RESULTS Oral extraction was successful in 89 horses and unsuccessful in 11 due to damage to the CT clinical crown (n = 9) during extraction, for behavioural reasons (n = 1) and because the apex of a partly extracted CT fell back into the alveolus following sectioning (n = 1). Predispositions to extraction-related CT fractures were present in 5 of the 9 cases, i.e. advanced dental caries (n = 2) and pre-existing 'idiopathic' fractures (n = 3). The iatrogenically fractured CT were later repulsed under standing sedation (n = 3) and under general anaesthesia (n = 6). Eighty-one of the remaining 89 horses had successful oral CT extraction with no or minimal intra- or post operative complications occurring. Post operative complications in the other 8 cases included post extraction alveolar sequestration (n = 3), alveolar sequestration and localised osteomyelitis (n = 1), localised osteomyelitis (n = 1), incorporation of alveolar packing material into alveolar granulation tissue (n = 1), and nasal discharge due to continued intranasal presence of purulent food material (n = 1) and to ongoing sinusitis (n = 1). The above sequelae were treated successfully in all cases, with general anaesthesia required in just one case. Following oral extraction, significantly (P<0.001) fewer post operative problems developed in 54 horses with apically infected CT in comparison with 71 previous cases that had repulsion of apically infected CT at our clinic. CONCLUSIONS AND POTENTIAL RELEVANCE Oral extraction of cheek teeth is a successful technique in the majority of younger horses with firmly attached CT and greatly reduces the post operative sequelae, compared with CT repulsion. Additionally, the costs and risks of general anaesthesia are avoided. Further experience and refinement in the described protocol could potentially increase the success of this procedure and also reduce the incidence of post operative sequelae.

Abstract
OBJECTIVE The aim of this study was to make estimates from a dental care and societal perspective on costs of mandibular third molar surgery. MATERIAL AND METHODS A total of 64 patients were recruited from three Swedish oral and maxillofacial specialist clinics. Calculations were made prospectively on utilization of labor time, specific medical services and materials, and standardized utilization of other direct costs. Indirect costs were identified from patient surveys. RESULTS The base case average direct cost of surgery was 217 Euro. Adding the patient's average cost due to absence from work and transportation of 333 Euro increased overall costs to 550 Euro per patient. About 86% of the patients reported some absence following surgery. CONCLUSIONS The indirect costs were on average higher than the direct costs, i.e. the patient's loss of time caused higher costs than the intervention per se. Appropriate indications for mandibular third molar removal can minimize the risks of complications and individual or societal costs.

Abstract
INTRODUCTION There are many possibilities of diagnosing and treating, but the fact of an increasing number of patients who have resigned from expensive procedures in place of teeth extraction is still noticeable. MATERIAL AND METHODS Poll analysis based on the population of a big city--Szczecin and small towns in West Pomerania revealed that one's wealth considerably impacts both the frequency of visits in dental practices and the decisions regarding a mode of treatment. RESULTS It further occurs that the most common reason of tooth extraction is caries and its later complications. Over 25% of patients from Szczecin and nearly 20% of interrogated people in provinces had to extract teeth because of an economical reason due to the lack of money for restoring treatment. It also appeared that a majority of people feel unsatisfied with the proceeding reorganization of the national health service and have not observed any positive tendencies effecting from this process so far.

Abstract
Ten million third molars (wisdom teeth) are extracted from approximately 5 million people in the United States each year at an annual cost of over $3 billion. In addition, more than 11 million patient days of "standard discomfort or disability"--pain, swelling, bruising, and malaise--result postoperatively, and more than 11000 people suffer permanent paresthesia--numbness of the lip, tongue, and cheek--as a consequence of nerve injury during the surgery. At least two thirds of these extractions, associated costs, and injuries are unnecessary, constituting a silent epidemic of iatrogenic injury that afflicts tens of thousands of people with lifelong discomfort and disability. Avoidance of prophylactic extraction of third molars can prevent this public health hazard.

Abstract
PURPOSE In this study we investigated patients that were hospitalized due to third molar (M3) complications. Specifically we analyzed frequency, age distribution, and outcome with respect to the M3 clinical status. PATIENTS AND METHODS We set up a prospective cohort study and included 100 subjects admitted for management of acute M3-associated complications. The clinical status of the M3 was defined as 1) prophylactic M3 removal, 2) therapeutic (nonelective) M3 removal, or 3) M3 present at the time of admission. Outcome variables were clinical infection markers (C-reactive protein, leukocyte counts) and economic parameters (treatment costs, length of hospital stay, and days of disability). Nonparametric tests were used for comparison of subpopulations (surgical vs nonsurgical, prophylaxis-related vs nonprophylaxis-related). RESULTS One third of the 100 patients were age 40 or older. Overall 80 severe infections, 11 mandibular fractures, 3 nerve injuries, 5 tooth/root luxations, and 1 postoperative hemorrhage were noticed. Twenty-seven complications resulted from prophylactic surgery, 44 from nonelective removal, and 29 from pericoronitis. Postoperatively, a 77-year-old male patient hospitalized with nonelective removal sustained fatal myocardial infarction. Treatment costs were 260,086 euro (mean 2,608 euro/case); total days of disability were 1,534. The postsurgical complications showed higher C-reactive protein values compared with pericoronitis-induced complications. CONCLUSIONS Within the catchment area of our institution, the majority of complications requiring hospitalization resulted from diseased third molars or their removal. Side effects of observational strategies such as the shifting of complications to higher ages deserve future attention.

Abstract
OBJECTIVE To assist clinical decision making for an individual patient or on a community level, this study was done to determine the differences in costs and effectiveness of large amalgams and crowns over 5 and 10 years when catastrophic subsequent treatment (root canal therapy or extraction) was the outcome. METHODS Administrative data for patients seen at the University of Iowa, College of Dentistry for 1735 large amalgam and crown restorations in 1987 or 1988 were used. Annual costs and effectiveness values were calculated. Costs of initial treatment (large amalgam or crown), and future treatments were determined, averaged and discounted. The effectiveness measure was defined as the number of years a tooth remained in a state free of catastrophic subsequent treatment. Years free of catastrophic treatment were averaged, and discounted. The years free of catastrophic treatment accounted for individuals who dropped out or withdrew from the study. RESULTS Teeth with crowns had higher effectiveness values at a much higher cost than teeth restored with large amalgams. The cost of an addition year free of catastrophic treatment for crowns was 1088.41 dollars at 5 years and 500.10 dollars at 10 years. Teeth in women had more favorable cost-effectiveness ratios than those in men, and teeth in the maxillary arch had more favorable cost-effectiveness ratios than teeth in the mandibular arch. CONCLUSIONS Neither the large amalgam or crown restoration had both the lowest cost and the highest effectiveness. The higher incremental cost-effectiveness ratio for crowns should be considered when making treatment decisions between large amalgam and crown restorations.

Abstract
Surgical removal of impacted lower third molars is widely carried out in general dental practice and in many institutional clinics. Despite the fact that there are well established indications for the removal of impacted lower third molars, prophylactic removal of these teeth is still being universally practiced. Some reports have estimated that the proportion of impacted third molars that are removed when no clinically sound justification for surgery is present is between 18% and 50.7%. Justifications for prophylactic surgery include the need to minimize the risk of disease (cysts and tumors) development, reduction of the risk of mandibular angle fracture, increased difficulty of surgery with age, and that third molars have no definite role in the mouth. This article critically examines the literature regarding the relationship between impacted lower wisdom teeth, cysts and tumor development, and mandibular fractures.

[PMID: 16920537 DOI: 10.1016/j.tripleo.2005.09.010] [Citation(s) in RCA: 32] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2005] [Revised: 08/15/2005] [Accepted: 09/12/2005] [Indexed: 11/29/2022]
Abstract
OBJECTIVE The aim of this study was to describe demographic and clinical patterns of subjects hospitalized with complications associated with third molars (M3). STUDY DESIGN The investigation was designed as a prospective cohort study composed of subjects admitted to hospital for management of M3-associated complications. The predictor variable was "clinical status of the M3" defined as (A) prophylactic M3 removal, (B) nonelective M3 removal, or (C) M3 present at the time of admission. Outcome variables were infection parameters, treatment costs, length of hospital stay, and days of disability. Postoperative complications (A and B) were compared to complications based on pericoronitis (C). Complications due to prophylactic removal (A) were compared to those arising from pericoronitis or from the removal of symptomatic teeth (B and C). RESULTS From January 2003 to December 2004, 45 deep space infections, 6 mandibular fractures, 2 lingual nerve injuries, 1 parapharyngeal tooth luxation, and 1 osteomyelitis were noticed. Fifteen complications resulted from prophylactic surgery (A), 25 from nonelective removal (B), and 15 from pericoronitis (C). Direct treatment costs were 147,000 euro (A: 42,000 euro; B: 74,000 euro; C: 31,000 euro). In 10 of the 15 patients of group C, deep space involvement resulted immediately from the first episode of pericoronitis. Neither clinical markers of infection nor economic parameters showed significant differences between the groups. CONCLUSION Within the catchment area of our institution, the majority of third molar-related hospitalizations resulted from diseased third molars or their removal.

Abstract
AIM There is an ongoing controversy about indications for prophylactic removal of third molars. The purpose of this retrospective study was to clarify the risk of preservation of lower third molars. MATERIAL AND METHOD In a 5-year period, 316 patients were registered who had received in-patient treatment for deep abscess formation, cyst formation or mandibular angle fracture in relation to lower third molars. A radiological analysis (panoramic radiographs) was performed to determine whether major pathological changes associated with lower wisdom teeth are related to their position. Third molar positions were studied in this in-patient group and in an out-patient group. The latter consisted of 300 consecutive patients with prophylactically removed impacted third molars without any pathology. The relationship between the positions and the different pathological changes associated with impacted lower wisdom teeth was analysed statistically using a new 'position score'. RESULTS The study revealed that the highest 'position scores' corresponding to a leading aberrant position correlated significantly with cyst formation. Lower scores corresponding to moderately aberrant or slightly irregular position were found with angle fractures, abscess formation, and in the control group as a whole. CONCLUSION This study indicates that prophylactic third molar surgery for teeth with high and strongly elevated 'position scores' is appropriate in order to prevent cyst formation or mandibular angle fractures in a population at risk for facial trauma. In addition to other factors, 'position score' data could be useful for development of a model for predicting severe complications related to (removal of) impacted lower wisdom teeth.

Abstract
This study describes the socio-economic burden and attitudes of children and their parents following replantation of avulsed incisors. Records of 80 patients with 99 avulsion injuries treated in a teaching hospital clinic from 1988 to 1999 were reviewed. Mean age at time of injury was 10.6 years (range = 6.6-17.7 years). Complete records for a minimum of 1 year were obtained for 43 patients with 60 replanted incisors. Mean treatment procedures provided during the first year included 5.5 diagnostic periapical radiographs, 1.9 occlusal radiographs, 1.3 pulpectomies, and 2.7 pulp medicament applications. The mean estimated treatment cost and direct time (dentist) for first-year post-trauma management was 1465 dollars CAD and 7.2 h, respectively. Treatment costs were significantly higher during the first year post-trauma for patients who had their incisors extracted (P = 0.04), but there was no significant difference in direct treatment time between the two groups (P = 0.19). Twenty-one patient-parent pairs were surveyed for a number of qualitative factors. Ninety per cent of patients and 86% of parents reported that school and work time was lost. Even after having gone through the painful experience of replantation, the demands of recall, and in some cases, extraction, the majority of patients (67%) and parents (81%) stated that they would have still made the same (replantation) decision. Patient and parent responses were not statistically different (P = 0.453). Almost half the parents stated they would be willing to pay over 2000 dollars CAD to save an incisor. Patients rated retention of an incisor as significantly more important than infraocclusion. This is the first study to quantify the treatment burden of replantation of avulsion injuries exclusively in the pediatric population. This study describes the socio-economic burden and responsibilities of patient/parent and dentist and their role in informed consent.

Abstract
OBJECTIVES This population-based study measured utilities (preferences measured under conditions of uncertainty) of dentin regeneration (DR), a potential new therapy, root canal therapy (RCT), and extraction (EXT). METHODS A representative sample of dentate adults (aged 18-69 years) was randomly selected from the Detroit area. A computer program was used to administer the standard gamble (SG) method and record utility score (US) for treatment options of a tooth with reversible pulpitis using the SG method. For the SG method, two anchor states were used: filled tooth with full oral health and filled tooth with severe and continuous pain leading to EXT. Additional data were obtained using a self-administered questionnaire. RESULTS Out of the 807 adults who resided in 446 screened and selected households, a final sample of 630 adults who resided in 368 households were interviewed. The mean US for DR with 75 and 95% success rates were 72.5 and 86.2 (on a 0-100 scale), respectively. The US for RCT and immediate EXT were 75.6 and 31.3, respectively. Eleven per cent of the adults valued DR with 95% success probability higher than a simple filling with full oral health for life. There were no statistically significant differences in the average US of DR between insured and uninsured adults. Factors such as gender, race, education, income and insurance status, experiences with EXTs or root canal treatment, regularity of dental visits, quality of life, and quality of oral health were not significantly associated with the scores of DR. There was, however, a small but significant interaction between race and dental insurance, and race and gender. CONCLUSION This population-based study found that DR was highly preferred to other standard treatment options.

Abstract
IN Quebec (Canada), the utilization of dental care services varies greatly from one social class to another: whereas the well-to-do visit the dentist often for check-ups, those most in need demonstrate a "wait-and-see" attitude. The objective of our research was to describe the dental care pathway of the underprivileged when confronted with symptoms, and to understand how this pathway might be interrupted and possibly lead to tooth extractions. We arranged 16 one-on-one interviews with adult Montrealers who had experienced a dental problem during the 12 months preceding the interview. These participants, 9 women and 7 men aged between 30 and 48, lived in great poverty: all were welfare recipients, and as such, enjoyed the benefits of a government programme that entitled them to free basic dental care. During the interviews, the interviewers asked the participants to describe their latest dental problem and their subsequent behaviour. The dental care pathway of our participants was characterized by a strategy of adapting to the symptoms. This process of adapting, which can last several months, is essentially an individual process in which the individuals often resort to self-medication to soothe their pain. They decide to visit a dentist when the pain is too great and self-medication is no longer effective. Once this decision is made, their dental care pathway may nevertheless be interrupted in two ways: first, in the failure to find a dentist, and second, later, in the failure to complete treatments that are not covered by the welfare program, such as endodontic treatment. The fragmented character of these dental care pathways refers us to two features of accessibility: financial accessibility and acceptability. With regard to financial accessibility, our study shows that the public coverage intended for welfare recipients presents major gaps. As for acceptability, our participants are strongly critical of the dental profession, and develop a culture of rejection of it.

Abstract
OBJECTIVE The aim of this research was to investigate the incidence of fully impacted teeth and their complications and to recommend suitable removal times for these teeth. METHOD AND MATERIALS One thousand patients who were referred to the Oral Surgery Clinic, Faculty of Dentistry, at Atatürk University were intraorally examined, and fully impacted teeth were determined from radiographs. The locations of fully impacted teeth and the complications they caused were recorded. A total of 110 patients with fully impacted teeth were divided into three age groups: 16 to 19 years, 20 to 35 years, and older than 35 years. RESULTS The incidence of fully impacted teeth was found to be 11.00%. The maxillary left third molars in females and the mandibular left third molars in males were the most frequently impacted teeth. Complications, such as pain, cysts, resorption of the impacted or adjacent teeth, infection, crowding, and axial changes in the position of the adjacent teeth, were associated with 28.42% of impacted teeth. Impaction was most frequent in the 20- to 35-year-old group. CONCLUSION Extraction of fully impacted wisdom teeth before they cause complication is the ideal approach. However, in economically developing countries, such as Turkey, extraction of these teeth after complications occur is the most suitable approach because of restrictions in governmental budgets and the patients' poor socioeconomic conditions and fear of dentistry and oral

Abstract
OBJECTIVE To investigate trends in oral surgery in England and Wales 1991-2000. METHODS Oral surgery procedure data were derived from Dental Practice Board and Department of Health Hospital Episode Statistics. RESULTS There was a 6% increase in minor oral surgery (MOS) procedures, including ordinary extractions, extractions of special difficulty, apicectomies and third molar removals, carried out in the General Dental Services (GDS) but the number of third molars removed fell by 32% after 1997. General anaesthetics (GA) administered in the GDS fell by 77% and the number of sedations rose 54% after 1998. There was concentration of minor oral surgery in practices: in the year 2000, 88% of practitioners carried out less than five third molar removals. In the Hospital Dental Service (HDS) there was a 98% increase in day surgery, and a 53% decrease in ordinary admissions for minor oral surgery. HDS waiting times remained constant over the ten year period. CONCLUSIONS The principal trends were substantial decreases in apicectomies, third molar removals after 1997 and GAs after 1998; increases in extractions of special difficulty and concentration of MOS in the GODS. Numbers of ordinary extractions did not change. In the HDS there was a large shift from in-patient to daycase provision which has facilitated expansion of maxillofacial surgery. This is an important example of NHS reconfiguration. Perhaps the most important implication of these changes concerns the place of MOS in vocational training.

Abstract
Preservation of the socket site architecture promotes better esthetics, easier prosthetic treatment, and restoration of the alveolar bone for implant or bridge replacement options. The purported simplicity of the simple extraction can be misleading if the bone housing or soft tissues have been ravaged by disease. This article provides guidelines for case selection, patient consultations, selection of appropriate materials, and a step-by-step methodology for completing successful extraction site therapy.

Abstract
OBJECTIVES In recent years, several critical outcome studies concerning the prophylactic removal of mandibular third molars have been published. These would appear to motivate a more restrictive approach today as compared with 10 years ago. The aim of the present study was to examine dentists' decisions on the prophylactic removal of impacted mandibular third molars over a 10-year period. METHODS Thirty-six cases were selected so as to represent an equal distribution of males and females, ages, angular position and degree of impaction of the molar. Twenty-six general dental practitioners (GDPs) and 10 oral surgeons judged the same cases on two occasions 10 years apart. RESULTS Calculated for each category of dentists, there was no significant difference in the mean number of molars designated for removal between the two occasions. Two GDPs and three oral surgeons presented a higher removal rate, whereas five GDPs presented a lower removal rate on the second occasion as compared to the first one. The dentists presented a considerable interindividual variation in removal rate, between 0 and 22 molars on the first occasion and between 0 and 25 molars on the second occasion. CONCLUSION In the decisions on prophylactic removal of mandibular third molars, there has been no change over the last 10 years towards a more noninterventionist attitude. Thus, the dentists seem not to have been influenced by the evidence that this intervention is not cost-effective.

Abstract
BACKGROUND Removal of wisdom teeth is one of the most common surgical procedures performed in the UK. Little controversy surrounds the removal of impacted third molars when they are associated with pathological changes such as infection, non-restorable carious lesions, cysts, tumours, and destruction of adjacent teeth and bone. However, the justification for prophylactic removal of impacted third molars is less certain and has been debated for many years. OBJECTIVES To provide a summary of existing evidence on prophylactic removal of impacted wisdom teeth, in terms of the incidence of surgical complications associated with prophylactic removal, and the morbidity associated with retention. METHODS A systematic review of the research literature was undertaken. METHODS - DATA SOURCES: An existing review formed the basis of this report, and additional literature searches were undertaken, including searches of electronic databases (MEDLINE, 1984-99; EMBASE, 1984-99; Science Citation Index, Cochrane Controlled Trials Register, National Research Register; Database of Abstracts of Reviews of Effectiveness), paper sources (including Clinical Evidence), and web-based resources. Relevant organisations and professional bodies were contacted for further information. METHODS - STUDY SELECTION Studies were selected for inclusion if they met the following criteria: (1) design - randomised controlled trials (RCTs), literature reviews, or decision analyses; (2) participants - people with unerupted or impacted third molars, or those undergoing surgical removal of third molars either as prophylaxis or due to associated pathological changes; (3) reported outcomes - either the pathological changes associated with retention of third molars, or post-operative complications following extraction. There were no language restrictions on study selection. METHODS - DATA EXTRACTION AND SYNTHESIS: Data from included studies were extracted into structured tables and individual study validity was assessed against methodological checklists. Data were summarised descriptively. Decisions relating to study selection, data extraction and validity assessment were made by two independent reviewers, and disagreements were resolved by discussion. For non-English papers, translators were recruited to assist with study selection and data extraction. RESULTS Forty studies were included in the review: two RCTs, 34 literature reviews, and four decision analysis studies. One RCT in the UK focused on the effects of retained third molars on incisor crowding (predominantly a cosmetic problem) in patients who had previously undergone orthodontic treatment. The results of this trial suggested that the removal of third molars to prevent late incisor crowding cannot be justified. Another on-going RCT in Denmark compares the effects and costs of prophylactic removal of third molars with removal according to morbidity. So far, this trial has recruited 200 participants, and preliminary results indicate that watchful waiting may be a promising strategy. However, more data and longer follow-up of patients are needed to conclude which treatment strategy is the most cost-effective. It is also known that a trial is on-going in the USA but no results are available so far. The methodological quality of the literature reviews was generally poor, and none of the reviews was systematic. Conclusions from nine reviews on anterior crowding suggested that there was only a weak association between retention of third molars and crowding. Six out of 21 reviews with a more general scope also concluded that the prophylactic removal of third molars was unjustified. Twelve general reviews did not conclude with a clear message about the management of third molars. Three reviews suggested that prophylactic removal of third molars is appropriate, but these reviews were of poorer methodological quality than the majority of other reviews. Three out of four papers focusing on surgical management expressed

Abstract
OBJECTIVE This paper examines the cost to the Iowa Medicaid program of hospitalizing young children for restorative dental care under general anesthesia, and describes the dental services received in this setting. METHODS Medicaid dental claims for young children receiving restorative dental care under general anesthesia during fiscal year 1994 were matched with corresponding hospital and anesthesia claims. RESULTS The total cost to the Medicaid program of treating a child in the hospital under general anesthesia was $2,009 per case. Less than 2 percent of Medicaid-enrolled children under 6 years of age who received any dental service accounted for 25 percent of all dollars spent on dental services for this age group, including hospital and anesthesia care. The most frequent type of procedure was stainless steel crowns (SSCs), with an average of almost six per case. CONCLUSIONS Early identification, prevention, and intervention are critically important to prevent the costly treatment of children with ECC in hospital operating rooms.

Abstract
OBJECTIVES Decisions to extract a tooth may be among the most critical in dentistry. The aim of this study was to prospectively investigate both clinical and nonclinical factors related to decisions to extract or retain teeth in private general dental practice. METHODS A convenience sample of 196 Iowa dentists in private general dental practice reported on 549 cases where decisions were made to extract or retain teeth as they occurred in their practices during a one-month period in May 1997. Bivariate and multivariate analyses were used to identify factors that differentiated between cases where a tooth (or teeth) was extracted and cases where an at-risk tooth was retained. RESULTS Of the 549 cases, 67 percent involved extraction, while the remainder involved alternatives to extraction. In comparing extraction cases to alternative treatment cases, we excluded 150 extraction cases because dentists reported that no alternative to extraction was available. Using Generalized Estimating Equations (GEE), we identified cost of treatment, presence of tooth mobility, poor prognosis of alternative treatment, and presence of gross caries as significant factors associated with extraction, while previous treatment of the tooth and concerns with patients' health were significantly associated with alternatives to extraction. CONCLUSIONS For teeth at risk for extraction, cost, substantial periodontal disease, and several clinical factors were predictive of extraction.

Abstract
PURPOSE OF INVESTIGATION The study was undertaken to identify the least costly, most effective and most cost-effective management strategy for asymptomatic, disease free mandibular third molars. METHODS AND PATIENTS A decision tree model of the outcomes of mandibular third molar retention and removal was constructed. Probability data for possible outcomes were obtained from a comprehensive literature review and entered into the decision tree. The cost to the NHS in treating each outcome was calculated. 100 patients attending the oral surgery clinics, University of Wales Dental Hospital rated the effect of each outcome on their own life. The cost and effectiveness data for each outcome were entered into the decision tree and the analyses were conducted by 'folding back' the decision tree based on the probabilities. MAIN FINDINGS Mandibular third molar retention was less costly (170 Pounds), more effective (69.5 effectiveness units on a 100 point scale) and more cost-effective (2.43 Pounds per unit of effectiveness) than removal (226 Pounds, 63.3 and 3.57 Pounds respectively). These findings were sensitive to changes in the probability of pericoronitis, periodontal disease and caries. PRINCIPAL CONCLUSIONS Mandibular third molar retention is less costly to the NHS, more effective for the patient and more cost-effective to both parties than removal. However, should the likelihood of developing pericoronitis, periodontal disease and caries increase substantially then removal becomes the more cost-effective strategy.

Abstract
In the nearly two decades since the National Institutes of Health conference, controversy and uncertainty have continued with respect to the diagnosis and treatment of impacted, nondiseased third molars in adolescents and young adults. Articles published over the past 10 years have studied the issue from the vantage point of risk management. Those who favor prophylactic removal justify this action on three premises: 1. All impacted third molars are potentially pathologic; therefore, prophylactic removal reduces or eliminates risk of future disease. 2. The presence of third molars can cause late crowding. 3. Removal during adolescence and young adulthood reduces risks of operative and postoperative complications compared with older patients. Those who favor conservative management offer three counter arguments: 1. Although impacted third molars do pose a risk of a pathologic condition, the risk is relatively small in comparison with the risks of operative and postoperative complications and the costs of unnecessary removal. 2. Although some investigators have shown a statistical association of third molars and late anterior crowding, the association is not strong enough to allow prediction of patients at risk. This is due principally to the high degree of individual variability, suggesting that many other factors interact in the development of postadolescent crowding. 3. Although studies have shown that morbidity is reduced when impacted, nondiseased third molars are removed during adolescence or young adulthood, the cost-risk-benefit data do not justify routine removal. Proponents of prophylactic removal argue that the benefits outweigh the risks. Proponents of conservative management argue that the scientific evidence is inconclusive in support of prophylactic removal. Unfortunately, much of the clinical research has been flawed. This has led to contradictory interpretations that have not fully clarified the relative risks and benefits of early intervention. Untrustworthy data have served only to fuel the debate and controversy concerning proper protocols. However, careful analyses of the published research show that routine removal of impacted or unerupted, disease-free third molars cannot be justified. A case-by-case management protocol that requires monitoring development represents the consensus of most researchers in this field.

Abstract
Controlling haemorrhage by using a celluloid splint as an adjunctive therapy in patients with bleeding disorders is very beneficial in dental extraction. However, this technique still requires specific replacement therapy. The use of fibrin glue as a local treatment in dental extraction, without the use of any blood product replacement, recommended to improve efficiency in controlling haemorrhage during dental extraction. This method was modified using a combination of celluloid splint and fibrin glue for use in dental extraction in bleeding disorder patients. It was found that this method was effective in controlling bleeding, was cost effective, did not require replacement therapy and posed no risk of viral transmission.

Abstract
A shift toward diagnostic and preventive dentistry in the last two decades is evident from the change in the number of dental procedures performed, as well as the change in the percentage of time spent performing different types of procedures. During the period 1975 through 1995, the average nominal fees for selected dental procedures increased. Once inflation was taken into account, however, the increase in the average real fees charged was more modest.

Abstract
The utilization of fibrin sealants in patients with hemostatic disorders has hitherto been very limited. Our experiences from 40 major and 8 minor surgical procedures, 10 circumcisions and 118 tooth extractions in 106 patients with hemophilia A, B or von Willebrand's disease, almost exclusively of the severe form, respectively, demonstrate the benefits regarding reduction of blood loss and requirements for systemic replacement therapy. The literature on the use of fibrin sealants in this group of patients, which mainly concerns dental procedures, is reviewed and compared with our data. The importance of the composition of the glue is also discussed in detail.

Abstract
PURPOSE To analyze and compare complications and side effects after removal of 1,500 mandibular impacted third molar teeth in three age groups. MATERIALS AND METHODS The sample comprised 868 patients, 462 women and girls and 406 men and boys aged 9 to 67 years. The patients were divided according to age into the following three groups: group A, aged 9 to 16 years; group B, aged 17 to 24 years; group C, older than 24 years of age. RESULTS The incidence of complications and side effects was 2.6% in group A, 2.8% in group B, and 7.4% in group C. All complications were temporary except in one instance of mandibular nerve paresthesia that occurred in a group C patient, in whom symptoms were still present 25 months after surgery. CONCLUSION This study showed no significant difference in the complication rate between groups A and B, but complications significantly increased in group C.
