Comparative evaluation of subgingival irrigation with propolis extract versus chlorhexidine as an adjunct to scaling and root planing for the treatment of chronic periodontitis: A randomized controlled trial. J Indian Soc Periodontol 2022; 26:151-156. [PMID: 35321296 PMCID: PMC8936014 DOI: 10.4103/jisp.jisp_613_20] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2020] [Revised: 05/08/2021] [Accepted: 06/27/2021] [Indexed: 11/06/2022] Open
Abstract
Background: This study was carried out to investigate the effectiveness of subgingival irrigation with propolis extract compared to chlorhexidine as an adjunct to mechanical debridement to bring out the restoration of periodontal health in patients with chronic periodontitis. Materials and Methods: Twenty subjects were selected and randomly assigned into two groups of ten subjects each, which received subgingival irrigation with 0.2% chlorhexidine (control group) and propolis extract (test group) after initial scaling and root planing on the 7th day and 15th day as an adjunctive treatment. Plaque index (PI), gingival index (GI), and probing pocket depth (PPD) were assessed at baseline, on the 15th day, and on the 30th day. Microbial analysis for the colony-forming unit (CFU) was done at baseline and on the 30th day. Results: Statistically significant reduction was observed in PI, GI, PPD, and CFU counts from baseline to 30 days in both the groups. On intergroup comparison, the group received irrigation with chlorhexidine showed slightly better results; however, this difference was statistically nonsignificant compared to the group that received irrigation with propolis. Conclusions: It was concluded that propolis extract is as effective as chlorhexidine as a subgingival irrigant in reducing the subgingival plaque formation and microbiota from periodontal pockets.

Abstract
Context The use of herbal compounds is a comparatively safer alternative to synthetic compounds for periodontal therapy. Aim This study aims to investigate effect of extracts from pomegranate in a chip and gel form on periodontitis following scaling and root planing in adult periodontitis patients. Settings and Design An in vivo prospective study. Materials and Methods Thirty patients of adult periodontitis with initial pocket depth ≥4 mm were enrolled into the research and divided randomly into three groups, (10 in every group). After baseline examination, scaling root planing of tooth was achieved. Then subgingival application of medicated chips in Group 1, gel in Group 2, and placebo in Group 3 was done. Plaque index, gingival index, probing pocket depth, and relative attachment ranges were recorded at baseline, 21 days and 45 days. Statistical Analysis Used Analysis of variance test. Results The study confirmed significant improvements of plaque index ratings in Group 1 at day 21. It showed significant improvements of gingival index scores, probing pocket depth, and clinical attachment at day 21 and 45. Gingival index rankings and probing pocket depth were extensively elevated altogether in three groups at day 21 and 45. Relative attachment degree was extensively raised in Group 1 and Group 2 at day 21 and day 45 and in Group 3 at day 45. The relative attachment degrees confirmed significance at day 21 between Group 1 and Group 2, and Group 1 and Group 3. Conclusion Pomegranate extracts in chip and gel shape may offer additionally advantages to scaling and root planing for remedy of periodontal pockets.

Abstract
Introduction: Periodontitis is inflammation of supporting tooth structure. Most individuals get affected by this disease if oral hygiene is not maintained. There are various mechanical and chemical methods for oral hygiene maintenance. In recent past, interest has been diverted toward the herbal/traditional product in oral hygiene maintenance as they are free from untoward effect. Aim: To assess the efficacy of subgingival irrigation with herbal extract (HE) as compared with 0.2% chlorhexidine (CHX) on periodontal health in patients who have been treated for chronic periodontitis, and still have residual pocket of 3–5 mm. Materials and Methods: This was a controlled, single-blind, randomized study for 3 months. Patients were allocated in two groups (n = 15 each): (1) 0.2% CHX (control group); (2) HE consisting of Punica granatum Linn. (pomegranate), Piper nigrum Linn. (black pepper), and detoxified copper sulfate (test group). Solutions were used for the irrigation using pulsated irrigating device, WaterPik. Clinical outcomes evaluated were plaque index (PI), sulcus bleeding index (SBI), probing depth at baseline, 15th, 30th, 60th, and 90th day. Microbiologic evaluation was done at baseline and 90th day. Results: Significant reduction in PI was seen in the group of irrigation with HE. While comparing SBI, irrigation with CHX shows a better result. Other parameters such as probing pocket depth and microbiological counting were similar for both groups. Conclusion: Irrigation with HE is a simple, safe, and noninvasive technique with no serious adverse effects. It also reduces the percentage of microorganism in periodontal pocket.

IPNs from Cyclodextrin:Chitosan Antioxidants: Bonding, Bio-Adhesion, Antioxidant Capacity and Drug Release. J Funct Biomater 2014; 5:183-96. [PMID: 25233262 PMCID: PMC4192612 DOI: 10.3390/jfb5030183] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2014] [Revised: 09/01/2014] [Accepted: 09/09/2014] [Indexed: 12/03/2022] Open
Abstract
IPNs are unique “alloys” of cross-linked polymers in which at least one network is synthesized and/or cross-linked in the presence of the other. IPNs are also known as entanglements of polymer networks that are ideally held together only by permanent topological interactions. The objectives of this study are to evaluate novel chitosan-based functional drug delivery systems that can be successfully incorporated into “dual action bioactive tooth restorative materials”. These materials should be capable of inducing an improved wound healing prototype. The novel hydrogels will be investigated with respect to the antioxidant capacity of conventional antioxidants, such as resveratrol, β-carotene and propolis, as a designer drug delivery system, with the use of SEM imaging for the characterization of the surfaces, bio-adhesive property, antioxidant capacity, free radical defence, antioxidant, active ingredient stability and reactive features of novel materials. The additional benefit of the site-specific “functional restorative material” for use in dressings to deliver antibiotics to wound sites can provide tissue compatibility and reduced interference with wound healing. The materials were tested using an effective in vitro free radical generation model as functional additive prototypes for further development of “dual function restorative wound healing materials”. We quantified the effects of functional designer biomaterials on the dentin bond strength of a composite and evaluated the bio-adhesive capacity of the materials in the two separate “in vitro” systems. The added benefits of the chitosan/vitamin C/cyclodextrin (CD) host:guest complex-treated hydrogels involved a positive influence on the tetracycline release, increased dentin bond strength, as well as a demonstrated in vitro “built-in” free radical defence mechanism and, therefore, acting as a “proof of concept” for functional multi-dimensional restorative wound healing materials with a built-in free radical defence mechanism. Based on our results, we can conclude that the CD:chitosan-antioxidant-containing hydrogels are a suitable carrier for tetracycline to be slow-released. Within the limitations of the study design, chitosan-based hydrogels are suitable materials for functional restorative and wound healing applications in vitro. Cytotoxicity data are currently being evaluated in our laboratory.

Abstract
OBJECTIVES The aim of this study was to evaluate the efficacy of subgingivally administered xanthan-based chlorhexidine gel when used in the maintenance phase following scaling and root planing (SRP) in the treatment of chronic periodontitis. MATERIALS AND METHODS A randomized, controlled, single-center study was conducted involving 92 sites in 46 systemically healthy patients suffering from moderate to advanced chronic periodontitis with isolated pockets. The selected sites were randomized to two treatment arms: Group A (SRP alone) and Group B (SRP + insertion of chlorhexidine gel after 1 month). The gingival index, plaque index, probing pocket depth (PPD) and clinical attachment level (CAL) were recorded at baseline and subsequently after 1 month and 3 months. RESULTS Both the groups showed significant reductions in PPD and CAL at both follow-up visits when compared with the baseline values (P<0.001). CONCLUSIONS The results suggest that the application of xanthan based chlorhexidine gel following SRP in the maintenance phase might be beneficial in treatment of the chronic periodontitis in comparison to SRP alone. Greater improvements may be achieved when antimicrobial agents are used following SRP.

Abstract
Periodontitis is the most common localized dental inflammatory disease related with several pathological conditions like inflammation of gums (gingivitis), degeneration of periodontal ligament, dental cementum and alveolar bone loss. In this perspective, the various preventive and treatment modalities, including oral hygiene, gingival irrigations, mechanical instrumentation, full mouth disinfection, host modulation and antimicrobial therapy, which are used either as adjunctive treatments or as stand-alone therapies in the non-surgical management of periodontal infections, have been discussed. Intra-pocket, sustained release systems have emerged as a novel paradigm for the future research. In this article, special consideration is given to different locally delivered anti-microbial and anti inflammatory medications which are either commercially available or are currently under consideration for Food and Drug Administration (FDA) approval. The various in vitro dissolution models and microbiological strain investigated to impersonate the infected and inflamed periodontal cavity and to predict the in vivo performance of treatment modalities have also been thrashed out. Animal models that have been employed to explore the pathology at the different stages of periodontitis and to evaluate its treatment modalities are enlightened in this proposed review.

Abstract
AIM The objective of this study was to compare the efficacy of scaling and root planing (SRP) alone versus tetracycline fiber therapy used adjunctively with SRP in the treatment of chronic periodontitis sites in maintenance patients. MATERIALS AND METHODS A total of 30 patients with a diagnosis of chronic periodontitis (60 localized chronic periodontitis sites) in the age group of 35 to 55 were selected. None of these patients had received any surgical or non-surgical periodontal therapy and had sites of periodontal pockets measuring 4-7 mm clinically and demonstrated radiographic evidence of moderate bone loss. Two non-adjacent sites in separate quadrants were selected in each patient for monitoring based on criteria that the sites had localized chronic periodontitis. Plaque index (PI) (sillness and loe) and Gingival-bleeding index (GI) (loe and sillness) were measured at baseline and 15(th), 30(th), 60(th), and 90(th)day. Clinical pocket depth (PD) and microbial analysis (MA) were analyzed at baseline and 90(th) day. RESULTS At 0 and 3 months adjunctive tetracycline fiber therapy was significantly better in reducing PI, GBI, (P<0.001) than S and RP alone. In comparison, the reduction in the PD was non-significant at 0 and 3 months (P<0.001). The microbial analysis showed significant reduction in Porphyromonas gingivalis and Prevotella intermedia though there was no significant reduction in the Actinobacillus actinomycetemcomitans. CONCLUSION Overall, these results indicate that fiber therapy significantly enhanced the effectiveness of SRP in the management of chronic periodontitis.

Abstract
AIM The aim was to assess the levels of HbA1c, C-reactive protein, and lipid profile in patients with type 2 diabetes mellitus by treating the pockets using collagen impregnated sustained release resorbable tetracycline fiber (periodontal plus AB fiber) following scaling and root planing (SRP). MATERIALS AND METHODS A total of 40 patients with type 2 diabetes mellitus were randomly distributed into two groups receiving either SRP and tetracycline fiber or SRP alone. Patients were evaluated clinically with gingival index, plaque index, probing depth, and relative attachment level, and bio-chemically with HbA1c, C Reactive Protein, and lipid profile at baseline, 1 month, and 3 months. RESULTS Significant reduction in all the clinical parameters was seen in the tetracycline group compared to the control group. Bio-chemical analysis also revealed similar results except for cholesterol and High density lipoprotein who did not show any significant reduction. CONCLUSION Locally delivered tetracycline as a better treatment modality compared to SRP alone.

Abstract
The effect of an oral irrigator (Water Pik, Intersante) with a subgingival tip (Pik Pocket Subgingival Tip, Intersante) in the reduction of gingivitis was investigated in a single-blind three-group study involving 45 volunteers (age 46.2+/-10.2). All volunteers (inclusion criteria: gingivitis or a superficial periodontitis) were examined and underwent professional tooth cleaning at the first appointment. They were then randomly distributed in three groups: one group used the irrigator with the subgingival tip once daily with just tap water, in addition to their regular oral hygiene; another group also used an herbal-based mouth rinse (Parodontax, GlaxoSmithkline) in the water of the irrigator; a third group did not use an irrigator or any irrigant and therefore served as control. All groups received professional oral care education at each appointment. The investigation period was 3 months. At baseline and after 4, 8, and 12 weeks, the plaque index (PI, scores 0-5), gingival index (GI, scores 0-3), bleeding index (BI scores 0-5), and sulcus fluid flow rate (SFFR, Periotron 6000) at the Ramfjord teeth were scored. At baseline and after 3 months, the probing depth (millimeters) was measured at six surfaces of all teeth. A significant reduction in BI, PI, GI, probing depth, and SFFR was observed within 3 months. With all volunteers, however, there was no statistically significant difference ( p>/=0.05, Wilcoxon-test, SAS 6.04) between the three groups at any time. The additional use of the Water Pik irrigator with the Pik Pocket subgingival irrigation device with or without an herbal mouth rinse showed no clinical benefit over professional education in oral hygiene alone.

Abstract
BACKGROUND Multicenter clinical trials have established that the adjunctive use of the subgingival controlled release of chlorhexidine, (CHX chip), significantly reduces probing depth (PD), improves clinical attachment levels, and reduces bleeding on probing compared to scaling and root planing (SRP) alone for periods of up to 9 months. The present report is based on a phase IV clinical trial to examine the adjunctive use of the CHX chip for routine periodontal maintenance therapy (RPMT) over 2 years. METHODS Eight hundred thirty-five (835) patients were recruited into the study. At baseline a CHX chip was placed in pocket sites with PD > or = 5 mm. The patients were scheduled to receive RPMT at 3-month intervals with repeated CHX chip placement at sites where the PD remained > or = 5 mm. Patients who did not attend the 24-month recall visit or who failed to attend 2 consecutive time frame examinations were excluded from the analyses. RESULTS The 595 patients included showed a continuous decrease in PD over 2 years of 0.95 mm. After 2 years, 23.2% of patients had at least 2 pockets showing a reduction in PD of 2 mm or more and 58.9% of the sites had been reduced to a PD of < 5 mm. Only 2.9% (n = 57) of the sites showed an increase in PD of > or = 2 mm. Adverse events were mild to moderate in nature and resolved spontaneously without medication. CONCLUSION The results of this Phase IV or follow-up trial indicate that the adjunctive use of the CHX chip is a clinically safe and effective treatment option for long-term management of chronic periodontitis.

Abstract
BACKGROUND Several antibacterial agents have been studied as a means to produce bactericidal or bacteriostatic activity as an adjunct to mechanical treatment of periodontal disease. The primary purpose of this study was to evaluate the efficacy of tetracycline strips administered singly or in multiples in conjunction with root planing, versus root planing alone, or to an untreated control. Secondary purposes were to compare gingival crevicular fluid (GCF) volume and GCF concentrations of tetracycline in pockets treated with strips; to evaluate strip insertion time; and to compare ease of placement for single or multiple strips. METHODS Using a 4-quadrant design, 4 test teeth in 24 patients were treated with either root planing and single strip application; root planing and multiple strip application; root planing alone; or an untreated control. RESULTS Single and multiple strip placement resulted in a significant reduction in probing depth (P = 0.033) compared to root planing and untreated groups. The multiple strip group significantly decreased bleeding on probing (P = 0.05) compared to all other treatment groups. There was no treatment effect on GCF; however, there was a significant reduction in the GCF volume over time (P = 0.001). The time required for placement was, on average, 1.9 minutes for single strips and 3.25 minutes for multiple strips. CONCLUSIONS Our data suggest that multiple strips are superior to a single strip in reducing bleeding on probing, and that local delivery of tetracycline is superior to root planing alone in reducing probing depth.

Abstract
Bacteremia originating from the oral cavity is common, but the role of bacteremia in the genesis of infective endocarditis and other distant site infections is unclear. Only a small percentage of oral flora have been associated with distant site infection. Important issues remain unresolved concerning the identification of patients at risk, the relative risk from invasive dental procedures versus naturally occurring bacteremia, and the impact of prophylactic antibiotics on the incidence, nature, magnitude, and duration of bacteremia from the oral cavity. This article addresses the controversies in infection management in patients at risk for distant site infection.

Abstract
This manuscript reviews the development over the last 20 years of the evidence supporting the clinical application of a controlled delivery device for the treatment of human periodontitis. The device is a monolithic ethylene vinyl-acetate fibre loaded with 25% w/w tetracycline HCI (tetracycline fibre). It releases tetracycline at a steady state rate of 2 microg/cm x h and results in the maintenance of essentially constant, highly-effective concentrations of tetracycline at the site of action. A series of controlled, randomised, single-blind, phase-III clinical trials including a total of 463 patients has indicated that: (1) tetracycline fibres result in significantly better outcomes than the scaling and root planing positive control; (2) combination of tetracycline fibres with subgingival mechanical debridement results in significant improvement over debridement alone. Evidence from these studies has led to approval of this treatment modality by the US Food and Drug Administration and by the European Union Regulatory Bodies. A clinical usage study involving 2711 subjects treated by 68 clinicians in Europe and North America indicated that the magnitude of the observed clinical outcomes is clinically relevant and that adverse events were rarely observed. A variety of clinical investigations aimed at the optimal incorporation of tetracycline fibres in a treatment strategy provide guidance in case selection. Cost of therapy and concerns of unnecessary usage of antibiotics should be considered. It is nonetheless concluded that combination of tetracycline fibres with mechanical debridement represents a documented treatment alternative, the application of which may offer clinical benefits to many patients.

Abstract
The safety and efficacy of a degradable, subgingivally placed drug delivery system containing 2.5 mg chlorhexidine (CHX) were evaluated in a randomized, blinded, multi-center study of 118 patients with moderate periodontitis. A split-mouth design was used to compare the treatment outcomes of scaling and root planing (SRP) alone with the combined use of SRP and the CHX in pockets with probing depths of 5 to 8 mm. The two maxillary quadrants were used for the two treatment arms of the study. Scaling and root planing was performed at baseline only, while the CHX was inserted both at baseline and at 3 months. Clinical and safety measurements including probing depth (PD), clinical attachment level (CAL), and bleeding on probing (BOP) as well as gingivitis, plaque, and staining indices were recorded at baseline, and at 1, 3, and 6 months. The average PD reduction in the CHX-treated sites was significantly greater than in the sites receiving SRP alone at both 3 and 6 months with a mean difference of 0.42 mm (P < or = 0.01) at 6 months. The reduction in CAL at the treated sites was greater than at the SRP sites, although the difference was statistically significant at the 6-month visit only. An analysis of patients with initial probing depths of 7 to 8 mm (n = 56) revealed a significantly greater reduction in PD and CAL in those pockets treated with CHX compared to SRP at both 3 and 6 months. The mean differences between test and control sites at 6 months were 0.71 mm and 0.56 mm PD and CAL respectively.

Abstract
This article reviews the current status of controlled local delivery of antibacterial agents in the treatment of periodontitis. The principle of local intrapocket delivery of antibacterial agents and their delivery are discussed. The dosage forms include fibers, film/slabs, and injectable systems, some of which are degradable, while others are not and need to be removed at the termination of the treatment. The antibacterial agents used cover a range of antibiotics as well as antiseptics, and the composition of the delivery systems, their reported use, and the clinical results are summarized. The use of these systems in clinical practice is relatively recent, and therefore their application and integration into the dental office are not yet clearly defined. Clinical applications that have been tested are critically reviewed, and clinical situations in which controlled delivery of antibacterial agents may prove to be clinically useful are suggested for scientific evaluation.

Abstract
A biodegradable drug delivery system containing 5% sanguinarium (Sa) was compared to vehicle control (VC), scaling and root planing (SRP), and supragingival plaque control (SPC) in the treatment of adult periodontitis in 2 well-controlled clinical trials. Studies were 4-quadrant (split mouth) designs at 2 centers each, having 94 (Study A) and 107 (Study B) patients. All patients had at least 3 pockets between 5 and 9 mm that bled on probing, in each quadrant. Probing pocket depth (PD), clinical attachment level (AL), bleeding on probing (BOP), and plaque index were recorded at baseline, 14, 30, 60, and 90 days. All treatments gave statistically significant reductions from baseline for PD and BOP, and significant gains for AL. For PD reduction, SRP was superior to all test groups at all time points in both studies (p < 0.001). Sa was superior to VC in Study A at 14 and 30 days and to SPC at all time points. For AL gain at 90 days, in both studies, SRP gave gains of 0.42 and 0.78 mm respectively with superiority seen over the SPC group at 90 days (p < 0.001) in study A only, For BOP reduction, in Study A SRP was superior to Sa, VC, and SPC at 60 and 90 days (p < 0.005) and in Study B superiority to Sa and VC was at 90 days and to SPC at 60 days (p < 0.05). Sa was superior to VC for pocket depth in deep pockets only. Sa failed to demonstrate superiority over VC on a consistent basis. Analysis of residual Sa indicates that Sa potency was insufficient to show an advantage beyond clinical effects inherent in treatments with VC and SPC.

Abstract
Within the assessment, planning, implementation, and evaluation phases of the dental hygiene process of care model, the hygienist can decide which antimicrobial mouthrinse is best suited for a patient's given periodontal condition. First, the initial periodontal condition and the home care of the patient is assessed. Next, the hygienist can plan which protocol, in-office and/or at-home, will best meet the needs of the patient. Implementation of a program can include antimicrobial mouthrinses as an adjunct to scaling and root planing in the office, and the mechanical removal of plaque at home. Finally, the hygienist can evaluate the concerted efforts of both patient and clinician. Patients with extensive crowns and bridges, implants, and orthodontics can also benefit from the use of antimicrobial mouthrinses.

Abstract
Fifty chronic adult periodontitis patients completed a 6-week controlled, double-blind, split mouth clinical study to determine the effects of subgingival irrigation with an antimicrobial mouthrinse on periodontal microflora, supragingival plaque, and gingivitis when used as an adjunct to normal oral hygiene. Qualifying subjects had at least four sites, two on each side of the mouth, with probing depths between 4 and 6 mm, which bled on gentle probing. Following baseline examinations, subjects received a half mouth scaling and prophylaxis and full mouth subgingival irrigation with either the antimicrobial mouthrinse or sterile colored water control professionally delivered. Subjects continued irrigation at home once daily for 42 days with their assigned rinse delivered via a subgingival delivery system. All sites in the mouth were scored at baseline and at day 42 for supragingival plaque, bleeding on probing, and redness. For the four selected periodontitis sites, probing depth and attachment level were measured at baseline and on day 42; additionally, supragingival plaque and gingival redness were scored on days 7 and 21. Subgingival plaque samples for microbiological analysis were harvested from the selected periodontal sites at baseline and on days 7, 21, and 42. Microbiologically, irrigation with the antimicrobial mouthrinse resulted in statistically significant reductions compared to control in putative periodontopathogens, including black pigmenting species, which persisted at 42 days. Clinically, subgingival irrigation with the antimicrobial mouthrinse produced a significant reduction in supragingival plaque (P < 0.001), bleeding on probing (P = 0.019), and redness (P = 0.017) compared to the control, whether or not the area irrigated received a prophylaxis.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
While the efficacy of oral irrigations with antimicrobial agents on the clinical and microbial parameters of gingivitis is well established, the study of the efficacy of intrapocket irrigants on periodontitis has yielded conflicting and inconclusive results regarding both clinical and microbiological parameters. The overall goal of this review paper is to summarize the available information on the efficacy of intrapocket irrigation in the treatment of patients with periodontitis. The following topics are addressed: 1) the penetrability of the irrigant; 2) pocket irrigation without scaling and root planing; 3) professional pocket irrigation following scaling and root planing; 4) irrigations between recalls; and 5) safety of intrapocket irrigation. Single irrigation of periodontal pockets for short periods of time before or after scaling and root planing has limited effects on periodontal healing. However, continuous irrigation of the periodontal lesion with agents such as povidone iodine during thorough scaling and root planing, such as that carried out under local anesthesia, has promise as an antimicrobial adjunct in periodontal therapy.

Abstract
New knowledge about the microbial etiology of periodontal diseases emerged in the 1970s and 1980s and led to widespread interest in the use of antimicrobial agents to treat periodontitis. The controlled-release delivery of antimicrobials directly into the periodontal pocket has received great interest and appears to hold some promise in periodontal therapy. Some techniques for applying antimicrobials subgingivally, such as subgingival irrigation, involve local delivery but not controlled-release. Controlled-release local delivery systems, in which the antimicrobial is available at therapeutic levels for several days, have been evaluated in several forms and using different antimicrobials. Although most studies with such systems have focused on drug delivery kinetics and "proof of principle" evaluations, some controlled clinical trials have recently been reported. The most widely tested system, monolithic tetracycline-containing fibers, has shown significant clinical benefit when used alone as compared to no subgingival therapy. Similarly, controlled trials involving chlorhexidine strips used subgingivally every 3 months in place of routine supportive periodontal therapy have shown significant clinical benefit for up to 2 years. Although these data are now emerging, many questions concerning the optimal use and role of this therapy in clinical practice remain. This review attempts to summarize and interpret current data and to outline key remaining questions that must be addressed as this technology is transferred into clinical practice.

Abstract
The aim of this study was to investigate the effects of using 0.2% Chlorhexidine digluconate in an pulsated jet irrigator by patients as part of their daily dental home-care measures. After initial assessment, 16 patients diagnosed as having adult periodontitis received scaling and polishing together with advice on the subgingival use of a pulsated jet oral irrigator with which they were supplied. 8 patients having 293 active sites with probing depths equal to or in excess of 4 mm used 0.2% chlorhexidine digluconate (CHX) in the oral irrigator, 2 x daily for 56 days. The other group of 8 patients with 253 active sites over 4 mm used a placebo as the irrigating solution. A modified dichotomous plaque index (MPI), gingival bleeding index (GBI) and probing pocket depths (PPD) were assessed on days 0, 28 and 56. Within-group comparisons showed that the CHX regime reduced MPI, GBI and PPD significantly but that the placebo group (PG) only achieved a significant reduction in the PPD. Between-group comparisons showed that the use of 0.2% CHX as an irrigant was significantly more effective than the placebo solution at reducing all the clinical parameters studied. The patients found the oral irrigator easy and pleasant to use, although all the CHX group developed staining to a varying extent. This double blind study demonstrated that 0.2% CHX used 2 x daily in an oral irrigator was effective at reducing plaque deposition, periodontal inflammation and probing pocket depths. The effects of using lower concentrations of chlorhexidine digluconate in this regime need to be investigated.

Abstract
The purpose of this study was to determine the incidence of bacteremia after a single professional subgingival irrigation with a 0.12% chlorhexidine gluconate mouthrinse (CHX) as well as after a subsequent scaling and root planing (S/RP) during the same visit. Thirty subjects each with at least 1 site that probed 4 mm or more and bled on probing were randomly assigned to the following groups: 1) irrigation with 0.12% CHX; 2) irrigation with sterile water; and 3) non-irrigated controls. To begin the study blood was drawn just before and 2 minutes after irrigation. Thirty minutes later, blood was drawn again just before and 2 minutes after S/RP at the same site. Specimens were cultured for anaerobic and aerobic microorganisms using standard cultural techniques. Eighteen blood cultures from 15 subjects yielded positive cultures resulting in 23 isolates. Gram-positive rods comprised 34.8% of the total isolates; Gram-positive cocci 34.8%, Gram-negative rods 21.7%, and Gram-negative cocci 8.7%. In the CHX group, bacteremia was detected in 5 subjects after irrigation and in 2 other subjects after S/RP. In the water group, bacteremia was detected in one subject after irrigation and in 4 subjects after S/RP. The control group had 3 bacteremias after S/RP. There was no significant difference between the incidence of bacteremia associated with irrigation by CHX or sterile water (P = 0.141). There was also no significant difference in the incidence of bacteremia after S/RP between the CHX and sterile water irrigation groups and in patients who did not receive irrigation (control group) (P = 0.88).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Selection of the appropriate case and clinical competency in treatment modalities results in success in nonsurgical periodontal therapy. The patient with early periodontitis with significant local factors in the form of professionally accessible plaque and calculus is the most receptive to nonsurgical periodontal treatment. The clinician must make decisions centering around the important question, "Can the patient, or moreover, can the therapist delivering the debridement, gain access to the microbial subgingival plaque on a frequent basis below the host defense threshold of the respective patient?" If the answer is "yes," nonsurgical periodontal therapy will be rewarding. If the answer is "no," other modalities such as periodontal surgery must be instituted.

Abstract
The purpose of the present study was to evaluate the effects of subgingival irrigations with tetracycline as a supplement to mechanical plaque control and root debridement on clinical conditions of periodontal furcation pockets. 20 subjects with molar teeth having furcation pockets of varying depths and different grades of furcation involvement served for the study. Following oral hygiene instruction and root debridement at baseline, test teeth were irrigated subgingivally by a professional with a solution of 50 mg/ml of tetracycline, and control teeth with saline every 2nd week for 3 months. Records of dental plaque, bleeding on probing, probing depth and probing attachment level were obtained at 0, 1, 2, 3, 6, 9 and 12 months. The results failed to demonstrate any significant differences between test and control teeth for any of the subgroups of furcation sites at any observation interval. It is suggested that future studies may need to be performed over longer periods of time, and that the antimicrobial agents may need to be administered in vehicles, which provide prolonged periods of active subgingival concentrations.

Abstract
The purpose of this study was to evaluate the duration of therapeutic effect after administration of the collagen film immobilized tetracycline (TC film). TC film or tetracycline non-immobilized placebo film was applied one time to the periodontal pocket (greater than or equal to 4 mm) of five periodontitis patients (20 teeth). The clinical and microbiological effects are summarized as follows: The group that received TC film continued to show significantly low values for bleeding upon probing the pocket depth for 3 and 4 weeks, respectively, after administration, but there was no significant difference in the plaque index or gingival index when compared with the group that received a placebo film. In the TC film group, the density of microorganisms and the proportion of motile rods and spirochetes were also significantly decreased 3 weeks after administration. These findings suggest that topically administered TC film remains both clinically and bacteriologically effective for 2 to 3 weeks.

Abstract
Dental research continued to grow during 1988. Unfortunately the quality does not always parallel the quantity of publications. This report obviously does not encompass all of the literature but focuses on studies that are related to trends and to matters that are considered controversial. Likewise the particular interests of the members of the American Academy of Restorative Dentistry were taken into consideration. The subjects covered include periodontics, preventive dentistry, bulp biology, craniomandibular disorders, ceramics, color in restorative dentistry, and dental materials.
