Abstract
Peri-implantitis can be explained using a multicausality model. Many factors are involved in the etiology of peri-implantitis, but patient compliance also plays a key role. Oral hygiene, attending recall visits, smoking behavior, and therapy comprehension are relevant factors that contribute to peri-implant health. The clinician should create the most optimal conditions for patients to facilitate adequate oral self-care and to help patients improve their oral hygiene skills. Implementation of a supportive periodontal therapy program is mandatory to control inflammation and plaque accumulation, as well as to keep the incidence of peri-implant diseases low. Patient compliance, including plaque control and dental follow-up, must be optimal. Consequently, precautions must be taken with patients treated with dental implants.

Abstract
Case Description. This case report describes the successful management of a left mandibular first molar with a combined periodontic-endodontic lesion in a 35-year-old Caucasian woman with aggressive periodontitis using a concerted approach including endodontic treatment, periodontal therapy, and a periodontal regenerative procedure using an enamel matrix derivate. In spite of anticipated poor prognosis, the tooth lesion healed. This case report also discusses the rationale behind different treatment interventions. Practical Implication. Periodontic-endodontic lesions can be successfully treated if dental professionals follow a concerted treatment protocol that integrates endodontic and periodontic specialties. General dentists can be the gatekeepers in managing these cases.

Abstract
Assessment of the periodontium has relied exclusively on a variety of physical measurements (e.g., attachment level, probing depth, bone loss, mobility, recession, degree of inflammation, etc.) in relation to various case definitions of periodontal disease. Periodontal health was often an afterthought and was simply defined as the absence of the signs and symptoms of a periodontal disease. Accordingly, these strict and sometimes disparate definitions of periodontal disease have resulted in an idealistic requirement of a pristine periodontium for periodontal health, which makes us all diseased in one way or another. Furthermore, the consequence of not having a realistic definition of health has resulted in potentially questionable recommendations. The aim of this manuscript was to assess the biological, environmental, sociological, economic, educational and psychological relationships that are germane to constructing a paradigm that defines periodontal health using a modified wellness model. The paradigm includes four cardinal characteristics, i.e., 1) a functional dentition, 2) the painless function of a dentition, 3) the stability of the periodontal attachment apparatus, and 4) the psychological and social well-being of the individual. Finally, strategies and policies that advocate periodontal health were appraised. I'm not sick but I'm not well, and it's a sin to live so well. Flagpole Sitta, Harvey Danger

Abstract
BACKGROUND The purpose of the present study is to examine the association between clinical and radiographic periodontitis measurements during 2 years of periodontal maintenance. METHODS Secondary analyses were performed from a 2-year, double-masked, placebo-controlled, randomized clinical trial evaluating the efficacy and safety of subantimicrobial dose doxycycline (SDD) in 128 postmenopausal osteopenic females with moderate-to-severe chronic periodontitis. Relative clinical attachment level (relative CAL) and probing depth (PD) measurements were made. Posterior vertical bitewings were taken for alveolar bone density (ABD) and alveolar bone height (ABH) measurements. Generalized estimating equations were used to model associations. RESULTS One-year ABD changes and 1-year relative CAL/PD changes did not predict 2-year ABH changes and ABH/ABD changes, respectively. Baseline relative CAL and PD were positively associated with baseline ABH loss (P <0.0001), and baseline PDs were associated with subsequent ABD and ABH loss (P <0.05 for each). Among placebo (but not SDD) participants, relative CAL changes were associated with concurrent ABD loss (P = 0.027) when considering 1- and 2-year changes combined. The odds of ABH loss were higher among sites with concurrent 1-year ABD loss versus no change (odds ratio [OR] = 3.15, P <0.0001) or concurrent PD increases versus no change (OR = 1.88, P = 0.0025) when considering 1- and 2-year changes combined. CONCLUSIONS In postmenopausal osteopenic females undergoing periodontal maintenance, baseline PD was associated with subsequent ABD and ABH loss. Although no longitudinal change preceded another measurement change, changes in PDs and relative CALs appeared to reflect changes in the underlying alveolar bone over time.

Abstract
BACKGROUND In patients with periodontitis, a quantitative prognostic assessment is needed in order to make evidence-based decisions about retaining teeth or extracting and replacing them with a dental prosthesis. METHODS One hundred and ninety eight patients receiving active periodontal treatment in 1989 or 1990 and complying with supportive periodontal therapy (SPT) over an average of 11.8+/-2.3 years were included in the study. A generalized linear model was established and fitted via generalized estimating equations to identify predictors for tooth loss during SPT. RESULTS Of the 4559 teeth present at baseline, 166 (3.6%) were extracted during active treatment and 249 (5.5%) during SPT. Baseline findings of diabetes mellitus (OR=4.17), reduced alveolar bone levels (OR=1.04 for each 1% increment), increased tooth mobility (III versus 0: OR=5.52), multiple roots (OR=1.82), and non-vital pulp (OR=2.24) were significant (p<0.05) predictors for tooth loss during SPT. Based on these parameters, a prognostic model was constructed that provides estimates of tooth survival probability when periodontal therapy is rendered. CONCLUSION Using a multivariate approach, a prognostic model was developed that may be of value for clinical decision making.

Abstract
The aim of this review was to analyse the literature to assess the possibility of an association between smoking and endodontic disease and the prognosis of endodontically treated teeth. The review of the prognosis of endodontically treated teeth involved taking account of any potential associations with smoking and endodontic disease and marginal periodontitis, and smoking and prosthodontic outcomes. In addition, the role of smoking in implant failure and surgical wound healing was analysed with a view to drawing parallels regarding the possible implications of smoking on the outcome of surgical endodontics. A MEDLINE and Cochrane library search including smoking and various endodontic keyword searches identified three papers which discussed the variables, and did not just mention them separately in the text. The literature demonstrates a paucity of evidence relating smoking with endodontic disease and prognosis, but nevertheless presents evidence of a possible influence on the prognosis of endodontically treated teeth in smokers and a likely increase in surgical complications. The possible merits of a smoking cessation protocol prior to surgical endodontics are also discussed.

Abstract
AIM The objective of this retrospective study was to assess the reasons for tooth loss in a sample of patients who underwent periodontal therapy and supportive periodontal therapy (SPT) in a Brazilian private periodontal practice. MATERIAL AND METHODS A sample of 120 subjects who had been treated and maintained for 10 years or longer was selected from patients attending a periodontal practice. All patients followed a similar treatment: basic procedures, re-evaluation and periodontal surgery where indicated. Reasons for tooth loss were categorized as periodontal, caries, endodontal, root fractures and extraction of retained or partially erupted third molars. RESULTS Of the 2927 teeth present at the completion of active periodontal treatment, 53 (1.8%) were lost due to periodontal disease, 16 (0.5%) for root fracture, six (0.2%) to caries, five (0.2%) for endodontic reasons and 31 (1.0%) were lost to extraction of retained or partially erupted third molars. Logistic regression analysis was performed to investigate the association between five independent variables with tooth loss due to periodontitis. Only age (> 60 years) and smoking were statistically significant (p < 0.05). CONCLUSION The findings of this survey were consistent with previous studies. Older subjects and smokers were more susceptible to periodontal tooth loss. In addition, patients with generalized chronic periodontitis were treated and maintained for long-term periods with low rates of tooth loss.

Abstract
The most fundamental premise in the current view of periodontal disease is that not all individuals are at equal risk for disease and disease progression. Studies reveal that about 5-20% of the population is at risk for severe disease progression. The purpose of this paper is to define at-risk patients, review risk factors and indicators of disease progression, and outline an evidence-based strategy that includes both self-care and professional care for maintaining periodontal health. Risk factors/risk indicators considered include history of previous disease, increased pocket depth and loss of clinical attachment, frequency of dental care, specific bacterial pathogens, and systemic/environmental host factors such as smoking, diabetes mellitus, genetics, and stress. Because host factors may have more influence on disease progression than periodontal pathogens, personal and professional maintenance care must include the role of the host in periodontal disease progression. By examining the evidence surrounding these complex issues, dentists and dental hygienists are able to determine the extent to which evidence supports available approaches to maintain periodontal health and control disease progression.

Abstract
The purpose of this paper is to provide an overview of the role of periodontal maintenance procedures in the treatment of periodontal diseases. Reliance on this position paper in patient management will not guarantee a successful outcome, as periodontal diseases typically involve complex causes and symptoms. Ultimately, decisions regarding the diagnosis, treatment, and management of disease, as well as subsequent preventive therapy, must be made by the treating practitioner based on specific circumstances presented by the patient.

Abstract
BACKGROUND The programme of supportive periodontal care (SPC) is essential to the long-term stability of patients with chronic periodontitis. The clinical strategy for SPC is often determined according to 'clinical needs' of the patient and is thus determined by clinical observation and individual decision-making rather than being based on the best available clinical evidence. OBJECTIVE To evaluate the effectiveness of supragingival prophylaxis vs. sub-gingival debridement for SPC following the treatment of chronic periodontitis. SEARCH STRATEGY Computerized for Medline and the Cochrane Oral Health Group Specialty Trials Register. Hand searching of the Journals of Clinical Periodontology, Periodontal Research and Periodontology. Reference lists from relevant articles were scanned and the authors of eligible studies were contacted to obtain additional information. SELECTION CRITERIA Studies were selected if they were designed as a prospective clinical trial in which patients with chronic periodontitis had followed a programme of SPC, which included at least one of the regimens of interest in part of the mouth, for a minimum of 12 months. DATA COLLECTION AND ANALYSIS Information regarding methods, patients, interventions (SPC), outcome measures and results were extracted independently, in duplicate, by two reviewers (P.A.H., G.McC.). Absent data were recorded as such and incomplete data were sought from the researchers wherever possible. RESULTS In all, 28 papers were identified by the manual and electronic searches; 11 papers were eligible for inclusion. Only one study reported a direct comparison of the two SPCs of interest. The data were reported as mean changes in probing depth and attachment level between baseline and the 12-month follow-up point. For coronal scaling DeltaPD = 0.59 mm [0.13], DeltaAL = -0.13 mm [0.19]. For subgingival debridement DeltaPD = 0.37 mm [0.15], DeltaAL = -0.14 mm [0.18]. There were no significant differences between the SPC regimens. The weighted mean DeltaPD [95% confidence intervals] for the five additional studies that reported supragingival prophylaxis as the SPC regimen was 1.15 mm [-0.17, 2.38]. The weighted mean DeltaPD [95% confidence intervals] for the four studies that reported subgingival debridement as the SPC regimen was 0.56 mm [0.37, 1.47]. The difference between the SPC treatments for the mean DeltaPD is therefore 0.23 mm. The confidence interval for the combined studies was very wide [0.37, 1.47] and very little additional information is gained unless some strong assumptions are made about the comparability of the populations from which the samples are drawn. Such an assumption was not considered appropriate. The weighted mean DeltaAL [95% confidence intervals] for the six additional studies that reported supragingival prophylaxis as the SPC regimen was 0.18 mm [-0.38, 0.74]. The weighted mean DeltaAL [95% confidence intervals] for the six additional studies that reported supragingival prophylaxis as the SPC regimen was 0.50 mm [0.11, 0.89]. The difference between the SPC treatments for mean DeltaAL is 0.32 mm. The confidence interval [-0.36, 1.00] is very wide and the data from the additional studies provide little extra information than that reported in the one study that compared the treatments directly. CONCLUSION It is not possible to make any firm recommendations regarding clinical practice based on the crude meta-analysis and the review of these 11 studies. The best available evidence indicates that SPC regimens of supragingival prophylaxis and subgingival debridement are comparable with respect to the clinical outcomes of probing depth and attachment levels at 12 months post non-surgical treatment.

Abstract
BACKGROUND Severe periodontal furcation invasion has long been a treatment dilemma for the clinician. Many techniques have been advocated in the treatment of multi-rooted posterior teeth ranging from conventional scaling and root planing (SRP), apically positioned flaps, root amputations, root resections, tunnel procedures, guided tissue regeneration, and restorations. The keys to success depend on the clinician's ability to access the furcation to remove local factors and create an environment that enhances the patient's own hygiene efforts. Long-term success in treating teeth with furcation invasion depends upon tooth retention and arresting the destructive processes within the furcation area. METHODS A Class III furcation invasion in a mandibular molar was treated by surgical access for SRP along with obliterating the furcation utilizing a resin ionomer restoration. RESULTS Initially, the patient was asymptomatic. Within 3 months of treatment, the patient presented with suppuration that was refractory to local efforts. Radiographs taken only 5 months postsurgery demonstrated advanced bone loss apical to the restoration. The tooth ultimately was extracted because mobility increased and the tooth became symptomatic. CONCLUSIONS The clinician must consider the multi-factorial etiology of periodontal breakdown within a furcation. For this patient, the technique of sealing off the exposed furcation with restorative material appeared to have resulted in progressive bone loss and accelerate tooth loss. This single case report is presented as a rebuttal to recently published articles, which have demonstrated excellent results when treating furcations with ionomer restorations.

Abstract
This is a retrospective study of 418 patients who received active periodontal treatment between the years of 1984 and 1990. The patients were instructed to return for supportive periodontal treatment (SPT) at 3 to 6-month intervals. The objective of this study was to evaluate patient compliance with periodic recall visits, and to study the relationship of bleeding upon probing in those who returned regularly. The patients were divided into 3 groups: patients who returned periodically for supportive treatment, patients who interrupted the proposed maintenance treatment, and patients who never returned after active periodontal treatment. Analysis was made for each group to correlate the degree of compliance with gender, disease classification, and type of treatment received. To analyze bleeding upon probing, 2 groups of patients were selected: a test group with 39 patients who had attended at least 10 recall visits and participated in the study for more than 40 months, and a control group of 21 patients who interrupted the SPT for at least 12 months. The results showed that 26% of the treated patients returned for SPT and, of those, 40% returned irregularly. There was a statistical significant difference in compliance in relation to disease classification and the type of treatment received, but no correlation was found between compliance and gender. There was a statistically significant difference in compliance between the test group and the control group in relation to the variation of the bleeding index.

Abstract
This clinical study evaluated the reinfection incidence by Actinobacillus actinomycetemcomitans (Aa), Porphyromonas gingivalis (Pg), and Prevotella intermedia (Pi) in periodontal pockets following scaling and root planing (SRP) and intra-pocket irrigation with antimicrobial agents in a patient population who did not receive supportive maintenance therapy. The number of target organisms was determined utilizing DNA probes. Forty-one (41) inflamed pockets > or = 5 mm with attachment loss and containing at least one target species were selected in 6 adult patients. Following a baseline clinical and bacterial examination, all patients received thorough SRP. In addition, 1 to 2 teeth in each patient were randomly assigned to each of the following 4 treatment modalities: 1) control group, no irrigation; 2) saline group, irrigation with 2 cc of 0.85% saline; 3) tetracycline group, irrigation with 2 cc of aqueous tetracycline HCl, 50 mg/ml (5%); and 4) chlorhexidine group, irrigation with 2 cc, respectively. All selected sites were non-adjacent. No additional therapy was rendered during the entire 1-year observation period. Clinical parameters and microbial analyses were recorded again at 1 week, and 1, 3, 6, 9, and 12 months post-treatment. The effect of antimicrobial irrigation on the reinfection rate of sites by Aa, Pg, and Pi was compared with that of the control groups (1 and 2) by ANOVA. No statistically significant differences were observed among the irrigation treatment groups with regard to any of the clinical or bacterial parameters studied. Therefore, the 4 treatment groups were combined into a single group whereby the rate of bacterial repopulation following extensive scaling and root planing could be ascertained. The infection incidence of sites at baseline (of total sites), 1 week and 12 months (of sites originally infected at baseline) was 14/41, 3/14, and 7/14 for Aa; 33/41, 6/33, and 12/33 for Pg; and 37/41, 3/37, and 12/37 for Pi, respectively. Thus, half or fewer of the originally infected sites became reinfected at 12 months despite lack of maintenance therapy. The results suggest that 1) a single episode of pocket irrigation with antimicrobial agents following thorough scaling and root planing did not affect the rate of repopulation of periodontal pockets by the tested pathogens; 2) thorough scaling and root planing has a lasting suppressive effect on selected periodontal pathogens for the majority of sites in patients with adult periodontitis; 3) pre-operative probing depth, the amount of gingival fluid flow and the composition of the subgingival microflora may serve as predictors for reinfection in the absence of maintenance care; and 4) reinfection of the treated sites by Aa, Pg, and/or Pi may constitute a risk factor that diminishes the effect of therapy in the absence of supportive maintenance care.

Abstract
One hundred and ninety-five teeth in 35 patients with periodontitis who had received both endodontic and periodontal treatment were evaluated 9 years after endodontic treatment and 8 years after periodontal treatment. Some 91.4% of cases were well maintained and 8.6% showed a deterioration in their periodontal condition. Twelve of the 195 teeth with endodontic treatment were lost, eight for periodontal reasons, three as a result of fracture and one because of caries, and the periodontal condition of 10 teeth had worsened. An apical lesion formed on one tooth. The results indicate that the risk of endodontic failure in this group of 195 teeth is very low, and that there is little risk of tooth loss for periodontal reasons, provided that the patients receive supportive periodontal treatment.

Abstract
Radiographic record audits were conducted on 63 patients diagnosed as having periodontitis who had been treated and maintained for 10 years or longer in dental school clinics. Acceptable bite-wing radiographs were available for 50 of these patients. Bite-wing radiographs taken 8 to 34 years apart (mean 14.9 years) were assessed for bone loss. Recall maintenance had been accomplished for 60% of these patients at 6 to 9 month intervals, while 24% had been seen more frequently. The mean annual rate of bone loss was 0.037 mm (range of -0.19 to 0.20). There were no significant differences in bone loss between maxillary/mandibular, molar/premolar, or mesial/distal sites respectively. Alveolar bone loss in this dental school population compares well with other reported studies. Progression of disease as assessed by radiographic bone loss in treated and maintained periodontitis patients is minimal.

Abstract
This study radiographically evaluated the correlation between the changes in alveolar bone level occurring in bony defects after periodontal therapy and the corresponding pretreatment defect angles. The defect angle was defined by the bony defect surface and the root surface. The changes were determined from identically exposed and processed radiographs obtained just prior to surgery and 15 to 18 months later. The defect angle was clearly correlated to the radiographic changes in alveolar bone level. Most defects with an angle less than 45 degree showed a gain of bone while defects with the largest defect angles showed a loss. In addition, defects on root surfaces without furcations showed better healing than defects associated with furcations.

Abstract
The relative changes with time, in the position of the coronal margin of the mesial and distal bone of proximal, angular infrabony defects, were investigated. Tracings of the radiographs of 51 mandibular posterior sites, treated by flap curettage, with a mean post-surgical duration of 11.8 years, were measured using a digitizer pad. The group consisting of shallow-side sites (N = 51), exhibited no significant change in the bone height with time; however, there was a significant decrease in bone height in the deep-side group (N = 51). The mean area of proximal bone decreased significantly with time. The defects were divided into early (N = 25) and advanced (N = 26) angular groups, and then into deep- and shallow-side subgroups. In the early defect group, there was a significant decrease in the mean bone height of the deep-side subgroup. There were no differences in the changes of mean bone level of the remaining 3 subgroups with time. There was no correlation between changes in bone levels of adjacent mesial and distal sides of angular defects with time (r = 0.27). There was no difference between the deep- and shallow-side groups in the number of sites which gained, lost or evidenced no change in bone height. In the study population, the bone height of 73% of the deep-side, and 84% of the shallow-side sites was either unchanged or in a more coronal position.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The retention of teeth diagnosed as periodontally "hopeless" may accelerate the destruction of the adjacent proximal periodontium. Studies determining the influence these teeth have on the health status of adjacent teeth appear nonexistent. It was the intent of this retrospective study to assess the status of the periodontium in adjacent teeth proximal to the periodontium of "hopeless" teeth. We evaluated 17 teeth, each being mesially adjacent to one "hopeless" tooth, in 17 subjects treated for periodontal disease. In each case, the "hopeless" and the adjacent teeth received the same treatment. Probing depths (P-D), radiographic alveolar bone level (R-BL) and the width of the periodontal ligament space (W-PL) were measured for both the adjacent interproximal and the nonadjacent interproximal surface for each hopeless tooth. At both pretherapy and posttherapy, there were no significant differences for any of the variables (P-D, R-BL and W-PL) for the adjacent interproximal surfaces with the nonadjacent interproximal surfaces. However, there was a significant reduction in the mean probing depth for the adjacent interproximal surfaces, pretherapy to posttherapy. No other significant changes were found in any of the other variables for either the adjacent or nonadjacent interproximal surfaces. These data suggest that teeth considered periodontally "hopeless" and retained have no effect on the proximal periodontium of adjacent teeth prior to and following therapy.

Abstract
This paper begins with a review of the literature on compliance. The medical literature suggests that patients with chronic illnesses tend to comply poorly, especially if the disease is not perceived by the patient as particularly threatening. The dental literature covers two principal areas: compliance with oral hygiene regimens and utilization of dental care by the public. These works show that most patients surveyed do not clean their teeth as they have been instructed, and most do not receive routine dental care. The reasons for this noncompliance are highly variable but include lack of pertinent information, fear, economics, and the patient's perception of lack of compassion on the part of the dental therapist. In periodontics the majority of studies have focused on the effectiveness of patient oral hygiene along with its modification and on maintenance therapy. Other work in the periodontal literature is discussed in light of the widespread noncompliance shown by our patients. A number of studies have been undertaken on how best to improve compliance. In general, it has been found that patients comply better when they are informed and positively reinforced, and when barriers to treatment are reduced. Suggestions are made for improving compliance in the periodontal office and for tailoring therapy to predicted compliance levels.

Abstract
A group of 162 maintenance patients, previously studied for compliance to suggested maintenance schedules, were surveyed for tooth loss over a 5-year period. The group was divided into those who complied to suggested maintenance schedules and those whose compliance was erratic. It was found that none of the patients who had complied to suggested maintenance schedules lost any teeth. In the erratic group, where all tooth loss occurred, it was found that the more often a patient presented for maintenance, the less likely he was to lose teeth. These findings are discussed in relation to current studies on efficacy of various therapies for periodontal diseases.
