Abstract
Background: Pain management is an everyday challenge in dentistry. Analgesics are the group of drugs prescribed for effective pain management, of which nonsteroidal anti-inflammatory drugs (NSAIDs) are the most commonly prescribed drugs. Selection of NSAIDs must be judiciously made considering their pharmacological properties and adverse effects. Aim: This study aimed to analyze the attitude toward analgesic prescription among practicing dentists and the awareness to update their knowledge about them. Materials and Methods: The study was carried out among 100 dental practitioners, where a questionnaire consisting of 16 questions was formulated based on the awareness of indication and contraindication, actual practice, and required future trends for updating the knowledge. The questionnaire was distributed among the practitioners; the answered questionnaire was collected and tabulated. Statistical analysis included χ2 test to evaluate the significance. Results: Of 100 dental practitioners, 63% prescribed drugs based on the diagnosis. Aceclofenac was found to be the effective drug in postoperative pain management, whereas paracetamol was considered to be the safest among NSAIDs in clinical conditions such as bleeding disorders, gastric irritation, chronic kidney disease, and during pregnancy. All practicing dentists showed their willingness to participate in awareness programs in updating their knowledge. Conclusion: This study showed that dental clinical practitioners are well aware of the drugs to be prescribed in different clinical conditions but pitfalls have been observed in areas of systemic complication, where continuous educational programs are needed to overcome the same.

Abstract
Objective To compare the frequency and severity of periodontitis in patients with spondyloarthritis (SpA) with healthy control individuals, through the evaluation of clinical, serological and microbiological periodontal condition. Methods Patients with a diagnosis of SpA (n=78) and biological disease-modifying antirheumatic drug (bDMARD) naive fulfilling the Assessment of SpondyloArthritis international Society (ASAS) classification criteria as well as 156 healthy controls matched for age/gender were included. Two trained and calibrated periodontologists performed the periodontal clinical assessment. The presence of periodontitis and its severity were determined according to the criteria established by the Centers for Disease Control and Prevention-American Academy of Periodontology. The clinical periodontal variables, IgG1/IgG2 antibodies against Porphyromonas gingivalis andperiodontopathic bacterial identification, were also established. Comparisons of periodontal characteristics between the patients with SpA and the control group were performed using univariable analyses. A logistic regression analyses was performed to calculate the OR (95% CI) for diagnosis of periodontitis in patients with SpA and matched controls. Results A diagnosis of periodontitis was established in 56% in patients with SpA versus 69% of healthy controls (P≤ 0.01). Severe periodontitis was found in 3% versus 12% in SpA versus healthy controls, respectively (P≤ 0.01). There was no significant increase of frequency of any periodontal variable, IgG1/IgG2 antibodies against P. gingivalis or the presence of periodontopathic bacteria between patients with SpA and control group. Periodontitis was not positively associated with a diagnosis of SpA (OR: 0.57, 95% CI 0.32 to 1.00, P=0.05) in the logistic regression analyses. Conclusions We found a lower rather than a higher frequency and severity of periodontitis in patients with SpA in comparison with healthy control individuals. Our findings suggest that there is no positive association between SpA and periodontitis in Colombian patients.

Abstract
OBJECTIVE To review the biological mechanisms and clinical utility of therapeutic modulation of the host response in the management of periodontal diseases. MATERIAL AND METHODS A search of MEDLINE-PubMed was performed up to and including December 2004. The search was limited to in vitro, experimental animal and clinical studies published in English. The selection criteria included all levels of available evidence: systematic reviews, randomised-controlled clinical trials, controlled clinical trials, prospective and retrospective cohort studies and case reports of human and experimental animal studies. RESULTS Six targets for non-microbial chemotherapeutic intervention were identified. Clinical trials have demonstrated the ability of non-steroidal anti-inflammatory drugs to slow periodontal disease progression. However, recently reported serious adverse effects preclude the use of cyclooxygenase-2 inhibitors as an adjunct to periodontal therapy. Adjunctive use of subantimicrobial dose doxycycline to non-surgical periodontal therapy is beneficial in the management of chronic periodontitis over 12 months. Controversial data exist on the effects of bisphosphonate administration as an adjunct to periodontal therapy. Evidence on modulation of other host mediators including lipoxins, cytokines and nitric oxide synthase is limited to animal research. CONCLUSION After validation in long-term clinical trials, adjunctive host modulation therapy may prove advantageous in the management of periodontal diseases.

Abstract
BACKGROUND Studies in humans have indicated that systemically administered flurbiprofen and ibuprofen may reduce gingivitis. De novo plaque formation is enhanced at tooth surfaces adjacent to inflamed gingivae. OBJECTIVE The aim of the present clinical trial was to evaluate the effect of systemic administration of ibuprofen on gingivitis and plaque build-up. MATERIAL AND METHODS Eleven subjects were recruited for the study and were given oral hygiene instruction, scaling and professional mechanical tooth cleaning (PTC). At the end of a preparatory period (Day 0), the participants were told to abstain from all mechanical plaque control measures during a 2-week experimental period but to rinse with an assigned mouth rinse (positive control: 0.1% chlorhexidine digluconate; negative control: saline) or administer ibuprofen (tablets of 200 mg twice daily). Mouth rinsing was performed twice a day (after breakfast and in the evening), for 60 s with 10 ml. Re-examination was performed after 14 days of experiment. After a 2-week "wash-out" period, the participants received a new PTC and a second 14-day experimental period was initiated. The experimental and "wash-out" periods were repeated until all volunteers had been involved in all three regimens. Dental plaque was scored using the Quigley & Hein Plaque Index system and gingivitis according to the Gingival Index (GI) system. Supragingival plaque was collected and prepared for dark-field microscopy. One hundred bacterial cells were counted and classified into six different groups: coccoid cells, straight rods, filaments, fusiforms, spirochetes and motile rods. Gingival crevicular fluid (GCF) was collected from the same sites that were sampled for plaque. The volume of GCF collected in each strip was measured and analysed regarding content of lactoferrin and albumin. RESULTS During the period when the panelists rinsed with saline they accumulated large amounts of plaque and developed marked signs of gingivitis. When they rinsed with chlorhexidine digluconate, small amounts of plaque formed and few sites received GI score > or =2. After the 2 weeks of ibuprofen administration, the panelists presented with significantly fewer sites that scored GI > or =2 but had formed similar amounts of plaque as during the negative control period. CONCLUSION It is suggested that ibuprofen administered via the systemic route has an effect on gingivitis but not on de novo plaque formation.

Abstract
AIM The aim of the present study was to characterize the subject-based clinical behavior of the gingiva in response to a tooth-cleaning regimen in two subpopulations, "high-responder" (HR) and "low-responder" (LR) groups, presenting a different inflammatory response to plaque accumulation. MATERIAL AND METHODS The study population comprised of 96 systemically and periodontally healthy subjects, 46 males and 50 females, non-smokers, enrolled in an experimental gingivitis trial. At completion of the experimental gingivitis period (day 21), all subjects were prescribed the same 21-day treatment regimen of amine/stannous fluoride (AmF/SnF(2))-containing toothpaste and mouthrinse. Plaque index (PlI), gingival index (GI), gingival crevicular fluid volume (GCF), and angulated bleeding score (AngBS) were recorded on three selected teeth. Treatment efficacy was evaluated in the overall population as well as in HR and LR groups, separately. RESULTS A statistically significant decrease of PlI was observed after treatment (p<0.001), with PlI reversing to baseline levels. Changes in PlI revealed the same trend in both HR and LR groups, without differences between groups. Treatment also resulted in a significant decrease of all gingivitis parameters (p<0.001 for all comparisons). After treatment, GI, AngBS, and GCF were comparable with baseline condition. However, when the two groups were compared, day 42-GCF was significantly higher in the HR group than the LR group. CONCLUSIONS A treatment regimen based on mechanical plaque control supplemented with AmF/SnF(2)-containing toothpaste and mouthrinse is effective in reducing plaque accumulation and re-establishing healthy gingival conditions after experimentally induced gingivitis, even in subjects with different inflammatory response to plaque accumulation.

Abstract
BACKGROUND The purpose of the present study was to evaluate the effect of a relatively selective cyclooxygenase (COX)-2 inhibitor (nimesulide) and non-selective COX-1/COX-2 inhibitor (naproxen) used as an adjunct to non-surgical (scaling and root planing [SRP]) periodontal therapy in chronic periodontitis patients on the gingival tissue (GT) levels of prostaglandin (PG)E2 and PGF2alpha. METHODS Thirty patients with chronic periodontitis were divided into 3 groups of 10 each. One group received 100 mg of nimesulide; one received 275 mg of naproxen sodium; and the third group received placebo tablets in a 2 x 1 regimen for 10 days as an adjunct to SRP. GT samples were obtained before drug intake and on day 10. Plaque index (PI) and papillary bleeding index (PBI) scores were recorded at baseline, day 10, and at 3 months; probing depth (PD) and clinical attachment level (CAL) were recorded at baseline and at 3 months. The levels of PGE2 were detected using an enzyme immunoassay (EIA), and the levels of PGF2alpha were analyzed by radioimmunoassay (RIA). Differences among and within the groups were assessed using non-parametric statistical analysis. Ten periodontally healthy individuals served as controls. RESULTS All 3 groups showed statistically significant reductions in PBI and PI on day 10 and at 3 months (P < 0.02), and in PD and CAL at 3 months (P < 0.02, P < 0.05, respectively). In the naproxen group, GT PGE2 levels exhibited a significant decrease (P < 0.05). However, the decrease of GT PGE2 levels in the nimesulide group was insignificant (P > 0.05), while a significant increase was observed in the placebo group (P < 0.05) on day 10. Both the nimesulide and naproxen groups showed a significant decrease (P<0.05) in PGF2alpha level, while the placebo group showed a significant increase (P<0.05). CONCLUSIONS Nimesulides, relatively selective COX-2 inhibitors, may have additional inhibitory effects on GT PGF2alpha levels in the first week following non-surgical periodontal treatment. However, nimesulide has an insignificant effect on reducing PGE2 levels in gingival tissue. The determination of GT levels of COX-1 and COX-2 enzymes as well as PGE2 and PGF2alpha in long-term studies may provide further support for the adjunctive use of selective COX-2 inhibitors in treatment of chronic periodontitis.

Abstract
The non-steroidal anti-inflammatory drugs (NSAIDs) are among the most widely used classes of drugs for the management of acute and chronic pain in dentistry. Their therapeutic efficacy and toxicity are well-documented and provide evidence that NSAIDs generally provide an acceptable therapeutic ratio of pain relief with fewer adverse effects than the opioid-mild analgesic combination drugs that they have largely replaced for most dental applications. The great many studies done with the oral surgery model of acute pain indicate that a single dose of an NSAID is more effective than combinations of aspirin or acetaminophen plus an opioid, with fewer side-effects, thus making it preferable for ambulatory patients. The combination of an NSAID with an opioid generally results in marginal analgesic activity but with an increased incidence of side-effects, which limits its use to patients in whom the NSAID alone results in inadequate analgesia. The selective COX-2 inhibitors hold promise for clinical efficacy with less toxicity from chronic administration and may prove advantageous for the relief of chronic orofacial pain. The use of repeated doses of NSAIDs for chronic orofacial pain should be re-evaluated in light of a lack of documented efficacy and the potential for serious gastrointestinal and renal toxicity with repeated dosing.

Abstract
BACKGROUND, AIMS This study investigated the periodontal status of non-smokers and ex-smokers in relation to their intake of low-dose aspirin. METHODS A self-selected sample of 392 males aged 50 years and over was recruited from the general population. Subjects were included in the study if they had a minimum of 6 or more natural teeth, took aspirin (300 mg or less per day) for at least 2 years and were either ex- or non-smokers. Controls were subjects who did not take aspirin regularly. A questionnaire was used to record demographic data, medical and dental histories. Individuals who had diabetes or other systemic diseases were excluded from the study. Periodontal attachment loss (PAL) was calculated by adding measurements of gingival recession and periodontal pocket depth made by a single examiner at 6 sites around each tooth using non-pressure sensitive periodontal probes. Plaque and gingival bleeding indices were also scored. Subjects were divided into 4 groups: aspirin non-smokers, aspirin ex-smokers, no aspirin non-smokers and no aspirin ex-smokers. Data were analysed using two-way ANOVA with age as the covariate. Severity and extent of mean PAL and the cumulative distribution of the mean of the most severe sites (MSS) of PAL were analysed. RESULTS Controlling for age, mean PAL in aspirin takers was significantly less 2.6+/-0.08 (se) mm than non-aspirin takers 2.9+/-0.06 (se) mm; this association was independent of smoking history. Ex-smokers had significantly more mean PAL 3.9+/-0.07 (se) mm than non-smokers 2.6+/-0.08 (se) mm, irrespective of aspirin status. When MSS-PAL was analysed, these differences became more pronounced; MSS-PAL in aspirin takers was significantly less 3.9+/-0.1 (se) mm than non-aspirin takers 4.2+/-0.08 (se) mm. Ex-smokers had significantly more MSS-PAL 4.3+/-0.08 (se) mm than non-smokers 3.8+/-0.08 (se) mm. Aspirin apparently had a protective association on PAL and it is hypothesised that low-dose aspirin may have reduced the rate of attachment loss. CONCLUSIONS This hypothesis needs to be confirmed by a prospective study. The results of this study suggest that individuals aged over 50 years, particularly ex-smokers, may benefit by taking low-doses of aspirin daily to reduce their risk of periodontal attachment loss.

Abstract
BACKGROUND It is just 100 years since the introduction of aspirin to medicine. Since then, aspirin and its derivatives have been joined by acetaminophen, and the nonsteroidal anti-inflammatory drugs--ibuprofen, naproxen sodium, and ketoprofen--as the only over-the-counter (OTC) agents approved by the US Food and Drug Administration for the short-term treatment of pain, headache, dysmenorrhea, and fever. Recently the prescription use of aspirin has expanded to include a number of antiplatelet indications. OBJECTIVE The purpose of this paper is to review critically the history, mechanisms of action, efficacy, and tolerability of OTC analgesic and antipyretic products. Relatively new and potential future indications for these drugs are also discussed. CONCLUSION Although all of the OTC analgesic/antipyretic agents seem to share a common mechanism of prostaglandin inhibition, there are important differences in their pharmacology, efficacy, and side-effect profiles. Considering their often-unsupervised use, the risk-benefit ratio of this class of drugs has been extremely favorable. However, when used inappropriately, even these drugs pose significant risks to certain patient populations.

Abstract
BACKGROUND Previous reports in the literature have shown that non-steroidal anti-inflammatory drugs (NSAID) may affect osseous tissues by either stimulating or inhibiting bone formation. This effect can be drug specific and different NSAIDs may produce opposite results. There are also reports showing that NSAIDs inhibit bone loss due to inflammatory disease process. The purpose of this randomized, controlled, blinded, clinical investigation was to determine the effect of a one week course of postsurgical naproxen on the osseous healing in intrabony defects. METHODS Twenty-four vertical osseous defects in 24 patients were treated with either a bioabsorbable membrane plus twice daily postsurgical naproxen 500 mg for one week (test or GPN group) or with a polylactide bioabsorbable membrane alone (control or GA group). Twelve patients were included in each group. Treatment was performed on either 2- or 3-wall or combination defects. All measurements were taken from a stent by a calibrated, blinded examiner and open measurements were repeated at the 9-month second stage surgery. Power analysis to determine superiority of naproxen treatment showed that a 12 per group sample size would yield 87% power to detect a 2.0 mm difference and 64% power to detect a 1.5 mm difference. RESULTS Open defect measurements from baseline to 9 months showed a statistically significant (P < 0.05) mean defect fill of 1.96 +/- 1.27 mm and 2.04 +/- 1.71 for the GPN and GA groups, respectively. This corresponded to a mean defect fill of 42% and a mean defect resolution of approximately 75% for both groups. The differences between GPN and GA groups were not statistically significant (P > 0.05). Defect fill of > or = 50% was seen in 6 defects (50%) in the GPN group and in 5 defects (42%) in the GA group. CONCLUSIONS The administration of postsurgical naproxen failed to produce osseous healing that was statistically superior to that obtained with polylactide bioabsorbable membranes alone.

Abstract
The anti-inflammatory effect of n-3 PUFA on the gingivae has already been demonstrated in animal models. The aim of this double-blind, randomized pilot study versus placebo is to evaluate this action in human experimentally-induced gingivitis. For 14 days (D0-D14), 37 healthy volunteers practised intensive oral hygiene, then abstained from brushing their teeth for 21 days (D14 to D35). On D28, the patients were randomized into 2 groups: 18 received the drug (fish oil: 30% n-3 PUFA) and 19 received the placebo (olive oil containing only 1% of n-3 PUFA) at a daily dosage of 6 g (i.e., 1.8 g of n-3 PUFA) 3x for 8 days (D28-D35). The plaque (PI), gingival (GI) and papillary bleeding (PBI) indices were measured on D14, D28 and D35. On D28 and D35, 10 volunteers underwent removal of an inter-dental vestibular papilla, between the 1st and the 2nd superior premolars, to measure out arachidonic acid (AA), eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA) and docosapentaenoic acid (DPA). A gingival biopsy was also taken in another 11 patients, to assay prostaglandin E2 (PGE2) and leukotriene B4 (LTB4). The clinical results of the trial demonstrated, in particular, a significant reduction of GI in the treated group (p < 0.05, Student t-test), but no significant difference between the groups. The biochemical results showed that EPA, DHA and DPA were found in the cells sampled, at higher levels in the subjects taking the drug, with a significant difference for EPA between the 2 groups (p < 0.05, Student t-test). The levels of AA, PGE2 and LTB4 are reduced in the experimental group and increased in the control group, with no significant difference. The LTB4 levels decreased but this difference just failed to reach significance (p = 0.09. Student t-test). This human experimental gingivitis study demonstrated that n-3 PUFA induced a tendency towards reduced inflammation but it was not possible to conclude significant efficacy.

Abstract
Non-steroidal anti-inflammatory drugs (NSAIDs) have been widely researched in an attempt to control periodontal diseases. This double-blind parallel group study investigated the effect of a systemic flurbiprofen preparation (100 mg daily), when combined with toothbrushing on the resolution of experimental gingivitis in human volunteers. 47 volunteers abstained from tooth cleaning for 21 days. On day 21, 23 subjects were prescribed 100 mg of flurbiprofen daily whereas 24 subjects were prescribed placebo. In both groups, toothbrushing was re-introduced and all subjects used the Bass technique for 2 min each day. Both treatment regimens were continued for 7 days. Plaque indices, gingival indices and gingival crevicular fluid flow were assessed at baseline (day 0) and on days 21 and 27. There were no significant differences at p = 0.05 between the groups for plaque indices or gingival crevicular fluid flow. The flurbiprofen group, however, demonstrated greater resolution of gingival inflammation by day 27 when compared to the placebo controls (p = 0.04). The plasma levels of flurbiprofen in the test group showed mean concentrations of flurbiprofen of 4.7 (+/- 2.1) micrograms/ml at 1 h after dosing. After 6 h, this had fallen to 4.4 (+/- 1.6) micrograms/ml. It is concluded that these serum concentrations of flurbiprofen are sufficient to produce significant anti-inflammatory effects in the gingival tissues.

Abstract
This clinical trial investigated the influence of short-term ibuprofen therapy on the early phase of the treatment of adult chronic periodontitis. The subjects were 17 patients in good general health referred for specialist periodontal treatment, having moderate chronic adult periodontitis. A series of assessments were made every 2 weeks over an 8-week period, including evaluations of oral hygiene, gingival inflammation and probing pocket depths. All participants received oral hygiene instruction, and following baseline examinations, had half the dentition, chosen at random, treated by scaling and root planing. The patients were randomly distributed into 2 groups, a test group receiving a 14-day course of 800 mg ibuprofen daily, in 4 divided doses, and a control group who did not receive any drug regime. At the 2-week assessment following the drug regime, significantly greater reduction in gingival bleeding, colour and pocketing was detected in the test compared with the control group. The beneficial effects were less evident thereafter. Although clinical application of the regime used in this study would not be justified by these results, further research into anti-inflammatory agents as an adjunct in the treatment of periodontal diseases could be considered, in the light of the beneficial effect on gingivitis in the early phase of periodontal treatment reported.

Abstract
Recent advances in the identification of specific immuno-inflammatory pathways of periodontal disease have encouraged investigators to attempt to modulate some of these host responses in an attempt to slow the periodontal disease process. Some of the best known mediators of these immuno-inflammatory pathways are prostaglandins. The action of prostaglandins can be inhibited through the use of non-steroidal anti-inflammatory drugs (NSAIDs). This review examines research over the last two decades during which the effect of several NSAIDs on the progression of gingival inflammation and alveolar bone loss was explored.

Abstract
An increasing body of evidence supports the concept that host-produced PGE2 mediates much of the tissue destruction that occurs in periodontal disease. PGE2 levels within the crevicular fluid can serve as a static assessment of ongoing disease activity; i.e., rate of attachment loss and bone resorption. New insights into the mechanisms that regulate PGE2 synthesis provide an altered paradigm of periodontal disease which places the emphasis on host response, rather than the bacterial etiology, as the principal determinant of disease expression. We described a PGE2 host response model as a hypothetical framework to discuss new, possible explanations for host susceptibility to periodontal disease.

Abstract
Recent interest in the control and modulation of periodontal disease has focused on the potential benefits of blocking the host response mechanisms involved in the progression of the disease. In addition to recent advances in the identification and control of etiologic bacteria, investigators have indicated promising results using nonsteroidal antiinflammatory drugs (NSAIDs) as inhibitors of the inflammatory destruction in periodontal disease. This article examines research efforts over the last 20 years describing the role of prostaglandins in periodontal disease and the effect of NSAIDs on the progression of gingival inflammation and alveolar bone loss.

Abstract
Simulation studies were conducted to address specific statistical issues which arise in the design and analysis of gingivitis studies whose principal aim is the demonstration of superiority or equivalence of one product to another. The effects of measurement scale, using differences or ratios of group means, particular statistical test produces and specific rules demonstrating superiority or equivalence were investigated. An alternative concept to equivalence--denoted "least as good"--was also defined and evaluated. For a wide class of possible distributions of gingivitis scores, characterized by specific gamma distributions, the student-t test applied to means of subject GI gingivitis scores proved to be the most powerful of the test produces considered, having statistical properties quite similar to the randomization or permutation test procedure. Transformations of subject GI mean gingivitis scores did not produce an advantage in demonstrating either superiority or equivalence, and in some cases made it more difficult. Little difference was observed in test results when using the difference in group means as compared with using the ratio of group means for demonstrating either equivalence or superiority. The clinically significant rule produced the lowest false-positive rates for products slightly better than the active control, and similar false-positive and -negative rates as the statistically significant rule for products clearly superior to the active control. Demonstration of product equivalence will require more subjects per group than demonstrating product superiority, the size of this difference being a function of the definition of superiority that is accepted. Showing that the 90% confidence interval for 100*R is completely contained within the [90%, 110%] interval is the preferred method of demonstrating equivalence today, although much more research needs to be done to improve methods for demonstrating product equivalence. The "least as good" alternative to "equivalence" makes it easier to demonstrate "equivalence" for products slightly better than the active control product, but both experience great difficulty in demonstrating equivalence for test products not quite as good as the active control.

Abstract
The non-steroidal anti-inflammatory drug(NSAID) naproxen was studied in 11 beagle dogs over a 13-month period to determine its effect on the progression of periodontitis. Following a 6-month pretreatment period, 5 dogs received naproxen daily at a dosage of 2.0 mg/kg for 1 month, then 0.2 mg/kg for 6 months. Six control dogs received a gelatin capsule daily as placebo. Standardized radiographs were used to measure the rate of bone loss during the pretreatment and treatment periods. In the control dogs, the rate of bone loss was seen to increase during the treatment period although the increase was not statistically significant. In dogs treated daily with naproxen, the rate of bone loss in the treatment period was significantly less at 4 months of treatment; however, at 7 months the difference, though lower than pretreatment rate, was not significant. When the percent change in rate of bone loss during the overall 7-month treatment period was compared with pretreatment rate, the control dogs demonstrated a 38% increase in rate of bone loss during the treatment period contrasting with a 61% decrease in bone loss rate in naproxen-treated dogs. The data indicate that the non-steroidal anti-inflammatory drug naproxen can significantly inhibit alveolar bone loss in beagles. At 4 months of treatment the rate of bone loss in the naproxen-treated dogs was significantly less than pretreatment, but at 7 months of treatment the rate was no longer statistically significantly less than baseline. This probably reflects a dose response to naproxen treatment for, after 30 days of the treatment period, the naproxen dosage was reduced 10-fold due to tolerance by the beagle.

Abstract
Subjects of the past decade in the dental literature are reflected in this year's Committee report. We note the decrease in the prevalence of caries, the influence of dental implants, the advancements in dental materials, and the continued efforts to control adhesive events in the oral cavity. This year we included comments from and about many significant review articles published this past year. The Committee continues to be concerned about the quality of some of the work reported and the quality of the reporting. We have attempted to select the distinguished work, that which provides new information to our profession. The subjects covered include pulp biology, caries prevention, periodontics, implants, craniomandibular function and dysfunction, occlusion, and dental materials.

Abstract
The role of bacteria in the initiation of periodontitis is well-documented and the end result, destruction of the alveolar bone and periodontal connective tissue, is readily observed; but the events occurring between these two points in time remain obscure and are the focus of this paper. Bacteria induce tissue destruction indirectly by activating host defense cells, which in turn produce and release mediators that stimulate the effectors of connective tissue breakdown. Components of microbial plaque have the capacity to induce the initial infiltrate of inflammatory cells including lymphocytes, macrophages, and PMNs. Microbial components, especially lipopolysaccharide (LPS), have the capacity to activate macrophages to synthesize and secrete a wide array of molecules including the cytokines interleukin-1 (IL-1) and tumor-necrosis factor-alpha (TNF-alpha), prostaglandins, especially PGE2, and hydrolytic enzymes. Likewise, bacterial substances activate T lymphocytes and they produce IL-1 and lymphotoxin (LT), a molecule having properties very similar to TNF-alpha. These cytokines manifest potent proinflammatory and catabolic activities, and play key roles in periodontal tissue breakdown. They induce fibroblasts and macrophages to produce neutral metalloproteinases such as procollagenase and prostromelysin, the serine proteinase urokinase-type plasminogen activator (u-PA), tissue inhibitor of metalloproteinase (TIMP), and prostaglandins, u-PA converts plasminogen into plasmin, which can activate neutral metalloproteinase proenzymes, and these enzymes degrade the extracellular matrix components. TIMP inactivates the active enzymes and thereby blocks further tissue degradation. Several amplification and suppression mechanisms are involved in the process. While LPS activates macrophages to produce IL-1, IL-1 is autostimulatory and can therefore amplify and perpetuate its own production. Interferon-gamma (INF-gamma) suppresses autostimulation, but it enhances LPS-induced IL-1 production. PGE2 exerts a control over the whole process by suppressing production of both IL-1 and TNF-alpha. Furthermore, the activated cells produce an IL-1 receptor antagonist that binds to the IL-1 receptor but does not induce the biologic consequences of IL-1 binding. Other cytokines such as transforming growth factor-beta (TGF-beta) suppress production of metalloproteinases and u-PA. Thus the progression and extent of tissue degradation is likely to be determined in major part by relative concentrations and half-life of IL-1, TNF-alpha, and related cytokines, competing molecules such as the IL-1 receptor antagonist, and suppressive molecules such as TGF-beta and PGE2. These molecules control levels of latent and active metalloproteinase and u-PA, and the availability and concentration of TIMP determines the extent and duration of degradative activity.
