RESUMO
BACKGROUND: There is insufficient clinical and microbiological evidence to support the use of diode laser and air-polishing with erythritol as supplements to scaling and root planning(SRP). The aim of the current study is to evaluate the clinical and microbiologic efficacy of erythritol subgingival air polishing and diode laser in treatment of periodontitis. METHODS: The study encompassed twenty-four individuals seeking periodontal therapy and diagnosed with stage I and stage II periodontitis. Eight patients simply underwent SRP. Eight more patients had SRP followed by erythritol subgingival air polishing, and eight patients had SRP followed by diode laser application. At baseline and six weeks, clinical periodontal parameters were measured, including Plaque Index (PI), Gingival Index (GI), periodontal Probing Depth (PPD), and Clinical Attachment Level (CAL). The bacterial count of Aggregatibacter actinomycetemcomitans(A.A), Porphyromonas gingivalis (P.G) was evaluated at different points of time. RESULTS: The microbiological assessment revealed significant differences in the count of A.A. between the laser and erythritol groups immediately after treatment, indicating a potential impact on microbial levels. However, the microbial levels showed fluctuations over the subsequent weeks, without statistically significant differences. Plaque indices significantly decreased post-treatment in all groups, with no significant inter-group differences. Gingival indices decreased, and the laser group showed lower values than erythritol and control groups. PPD and CAL decreased significantly across all groups, with the laser group exhibiting the lowest values. CONCLUSION: The supplementary use of diode laser and erythritol air polishing, alongside SRP, represents an expedited periodontal treatment modality. This approach leads to a reduction in bacteria and improvement in periodontal health. TRIAL REGISTRATION: This clinical trial was registered on Clinical Trials.gov (Registration ID: NCT06209554) and released on 08/01/2024.

BACKGROUND: High occlusal forces in patients with untreated periodontitis may reflect occlusal trauma-associated periodontal conditions. Occlusal analysis using T-scan might provide the distribution of occlusal loading forces in periodontitis patients. The study aimed to evaluate the effect of occlusal trauma in periodontitis patients and occlusal calibration using a T-scan. MATERIALS AND METHODS: A total of 30 periodontitis patients were recruited for the study. Patients were categorized into two groups: Group I: scaling and root planing followed by T-scan recording and no occlusal calibration; Group II: scaling and root planing followed by occlusal calibration using T-scan. Clinical parameters, orthopantomogram (OPG) and T-scan evaluation were evaluated at baseline, 3-month and 6-month intervals. RESULTS: Significant improvements in clinical parameters were noted at different time intervals after occlusal calibration using T-scan. At 3-month intervals, mean pocket depth showed statistically significant difference among the test group in the right (upper and lower) and left lower quadrant at P = 0.01, 0.002 and 0.005, respectively. Mean clinical attachment level (CAL) showed statistically significant difference among the test group in the right upper, right lower and left lower quadrants at P = 0.02, 0.001 and 0.009, respectively, at 3 months. The comparison of the mean gingival index (GI) at 6 months showed statistically significant difference among test and control groups at 6 months in different study quadrants (P = 1 in right upper, 0.009 in right lower, <0.001 in left upper and <0.001 in left lower). Mean pocket depth at the 6-month follow-up showed statistically significant difference among the test group in all the study quadrants (P = <0.001 in right upper, <0.001 in right lower, 0.003 in left upper and 0.005 in left lower). Mean CAL showed statistically significant difference among the test group in all the study quadrants at 6-month intervals (P = 0.02 in right upper, <0.001 in right lower, 0.01 in left upper and 0.04 in left lower). The bone defect height showed a statistically significant difference only in the right upper quadrant among both the test groups at the 6-month follow-up (P = 0.02). Comparing the mean percentage of force on both sides of the jaw showed a statistically significant difference among the test group at 6 months (P = 0.001 on the left side and 0.001 on the right side). CONCLUSION: The occlusal correction using T-scan showed a positive association between probing pocket depth (PPD) and CAL at different time intervals from baseline to 6 months when these parameters were compared after occlusal adjustments.

AIM: This study aimed to compare the efficacy of subgingivally applied probiotics as an adjunct to scaling and root planing (SRP) vs SRP alone in patients with periodontitis. MATERIALS AND METHODS: Patients diagnosed with periodontitis, with probing pocket depth (PPD) of 5-7 mm on at least two teeth on contralateral sites, were selected for the study and randomly allocated to the test group (n = 31) who underwent SRP along with subgingival application of probiotic paste and the control group (n = 31) who underwent only SRP. Clinical parameters were evaluated in both groups at baseline and after 12 weeks. The viability of probiotic bacteria was evaluated in the test group at baseline, day 4 and day 8. RESULTS: All clinical parameters showed a statistically significant difference between baseline and 12 weeks on intragroup and intergroup comparison, with a greater improvement in the test group. Microbiological evaluation showed that the mean colony-forming units (CFUs) in the test group were 38.39 ± 7.76, 7.25 ± 2.72 and 1.57 ± 1.29 at baseline, day 4 and day 8, respectively. The mean CFUs significantly reduced with an increase in time from baseline to 8-day time interval. CONCLUSION: It was seen that the probiotic bacteria remained viable in the periodontal pocket for up to 8 days after placement, but stable improvements were seen in all clinical parameters even at 12 weeks, indicating its prolonged efficacy. Thus, commercially available probiotics can prove to be an inexpensive method to treat periodontitis when combined with SRP.

OBJECTIVES: This study aimed to evaluate the impact of scaling and root surface debridement (SRP) on salivary bacterial counts and systolic and diastolic blood pressure in hypertensive patients with chronic periodontitis, with a focus on clinical significance. METHODS: An observational trial included 24 chronic periodontitis patients, eleven of them were hypertensive patients. Non-surgical periodontal treatment was administered to all patients, with clinical parameters including gingival index (GI), plaque index (PI), and probing pocket depth (PPD) recorded. Saliva samples were collected before and after SRP to quantify total bacterial counts and specific bacterial counts. RESULTS: Two months following SRP, PI and PPD in every subject under study demonstrated good responses. In hypertension patients, the salivary bacterial count was significantly higher following SRP (P = 0.0221). The incidence of Porphyromonas gingivalis in hypertension patients significantly decreased after treatment (P = 0.0386). Despite this, there was no discernible decrease in blood pressure following treatment. CONCLUSIONS: SRP alone was ineffective in reducing overall bacterial counts, but P. gingivalis levels responded favorably. Regular periodontal assessment is crucial for hypertensive individuals to mitigate cardiovascular risk. CLINICAL SIGNIFICANCE: Periodontal therapy in hypertensive patients may improve oral health but might not significantly impact blood pressure. Regular periodontal evaluation is essential for managing cardiovascular risk in hypertension.

BACKGROUND: Idiopathic gingival enlargement is associated with plaque, but other contributing factors are unclear. The prognosis of idiopathic gingival enlargement is closely related to the patient's oral hygiene habits and regular follow-up. CASE PRESENTATION: This article reports a case of a 32-year-old male patient with idiopathic gingival enlargement. The patient presented to the department of stomatology with a 2-month history of gingival swelling and pain on the right upper posterior teeth. During the treatment, oral hygiene instruction, supragingival cleaning, subgingival scaling, and root planning were carried out, and part of the hyperplastic gingiva was taken and sent for pathology. Pathological examination showed gingival enlargement with chronic suppurative inflammation. At 4-month follow-up, the patient's periodontal condition remained basically stable, and the gingival enlargement did not recur. CONCLUSION: The treatment of this case resulted in significant reduction of gingival swelling and patient's pain reduction through non-surgical treatment and good plaque control, indicating that patients with idiopathic gingival enlargement can also achieve ideal results through non-surgical treatment. Through oral hygiene instruction, the patient mastered the method of self-plaque control, which is conducive to the long-term stabilization of the periodontal situation.

BACKGROUND: This study aimed to demonstrate the efficacy of erbium, chromium-doped:yttrium, scandium, gallium, and garnet (Er,Cr:YSGG) laser-assisted nonsurgical periodontal therapy in periodontitis patients during 8 weeks of healing. METHODS: A split-mouth, single-blinded, randomized controlled clinical trial was conducted on 12 patients diagnosed with stage III/IV periodontitis and had a minimum of two teeth with probing pocket depth (PPD) > 5 mm in at least two quadrants. Upon randomization, each quadrant was assigned for conventional scaling and root planing (SRP) procedure or laser-assisted therapy (SRP + laser) using radial firing tip (RFPT 5, Biolase). Clinical measurements and gingival crevicular fluid collection were performed for statistical analysis. RESULTS: In the initial statistical analysis on the whole subject teeth, modified gingival index (MGI) reduction was greater in test group at 1(P = 0.0153), 4 (P = 0.0318), and 8 weeks (P = 0.0047) compared to the control in the same period. PPD reduction at 4 weeks in test group was -1.67 ± 0.59 showing significant difference compared to the control (-1.37 ± 0.63, P = 0.0253). When teeth with mean PPD ≥5 mm were sorted, MGI decrease was significantly greater in test group at 1 (P=0.003) and 8 week (P=0.0102) follow-ups. PPD reduction was also significantly greater in test group at 4 week period (-1.98 ± 0.55 vs -1.58 ± 0.56, test vs control, P=0.0224). CONCLUSIONS: Er,Cr:YSGG-assisted periodontal therapy is beneficial in MGI and PPD reductions during early healing period.

AIM: This study evaluated the efficacy of quadrantwise subgingival instrumentation (Q-SI) versus one-stage full-mouth subgingival instrumentation (FM-SI) on probing depth and periodontal pathogen reduction over a 6-month follow-up period, as well as whether baseline periodontal pathogens influenced the impact of periodontal treatment protocols on outcomes. METHODS: Patients with periodontitis were randomized to receive Q-SI (n = 43) or FM-SI (n = 45). Patients were instructed and motivated to maintain optimal oral hygiene during the treatment sessions. Clinical (probing pocket depth [PPD], clinical attachment loss [CAL], and bleeding on probing [BOP]) and periodontal pathogens were assessed at baseline and after 30, 90, and 180 days. Total bacterial load and periodontal pathogens were analysed via real-time PCR. RESULTS: At the 6-month follow-up, the median PPD decreased from 4.8 mm (interquartile range [IQR]: 4.3-5.2) to 2.6 mm (IQR: 2.3-2.9) in FM-SI patients and from 4.7 mm (IQR: 4.1-5.2) to 3.2 mm (IQR: 2.4-3.5) in Q-SI patients (p < .001). At 6 months, FM-SI was more effective at reducing the median proportions of Porphyromonas gingivalis (Pg), Aggregatibacter actinocomyctemcomitans, and Tannerella forsythia (Tf) (p < .001 for each value). Multilevel linear regression analysis demonstrated that high baseline PPD (p = .029), Pg (p = .014), and Tf (p < .001) levels and the FM-SI protocol (p < .001) were statistically significant predictors of PPD reduction at 6 months. Furthermore, PPD reduction was significantly greater in the FM-SI group when lower baseline Pg levels were detected. CONCLUSION: The FM-SI was more effective than the Q-SI in reducing the mean PPD and number of periodontal pathogens in periodontitis patients over a 6-month follow-up period. Higher baseline PPD and Pg levels had a negative impact on PPD reduction at 6 months after FM-SI.

BACKGROUND: The aim of this study was to assess the efficacy of photodynamic therapy (PDT) as an adjunct to scaling and root planing (SRP) on clinical parameters and microbial composition in subgingival plaque of periodontitis patients. METHODS: Seventeen patients were included in this split-mouth randomized clinical trial. Sites with probing pocket depth (PPD) ≥5 mm in combination with bleeding on probing in different quadrants were randomized into the control group, the group with a single PDT application right after SRP, and the group with three repeated PDT applications 1 week after SRP. The subgingival plaque was collected for 16S rRNA gene sequencing at baseline, Week 2, and Week 8. RESULTS: Seventeen patients with 60 sites completed this 8-week follow-up, and 157 subgingival plaques were successfully analyzed by sequencing. Significant improvements were observed in two primary outcomes: PPD at Week 8 and subgingival microbial composition. Compared to the control group, the repeated-PDT group showed a notable improvement in PPD, substantial alterations in the microbial profile, including a reduction in α-diversity and anaerobic bacteria, and an increase in aerobic bacteria at Week 2. Secondary outcomes, such as clinical attachment level and sulcus bleeding index, also showed improvement at Week 8. Furthermore, both the single- and repeated-PDT groups exhibited a decrease in periodontopathogens and an increase in beneficial bacteria compared with baseline. CONCLUSION: PDT promotes changes in the microbial composition of periodontitis patients' subgingival plaque in a direction favorable to periodontal health, and repeated PDT is a promising adjunctive therapy for periodontal treatment.

OBJECTIVES: This study aimed to evaluate the effect of virtual reality distraction (VRD) on dental anxiety during scaling and root planing (SRP) in periodontitis patients. MATERIALS AND METHODS: This randomized controlled split-mouth study included 60 patients who scored 9 or above on the dental anxiety scale (DAS) and required SRP in at least two quadrants with at least five teeth and two sites with a probing depth of ≥4 mm. Randomly chosen quadrants were treated using virtual reality glasses, and other quadrants were treated without glasses at the same visit. During VRD, a video of nature scenes was projected onto the screen in front of the patient's eyes. DAS and a visual analogue scale about patient feelings were applied at the end of the procedure. RESULTS: With VRD, the scale value of pain and discomfort level (VASP) was significantly reduced (p = 0.01, d = 0.57). Starting treatment without glasses significantly decreased VASP in both control and test sides (p = 0.00, d = 0.85; p = 0.00, d = 0.80, respectively) and increased the sensation of immersion and realism (p = 0.03, d = 0.45; p = 0.02, d = 0.46, respectively). Intraoperative and postoperative DAS values were significantly lower in patients who started treatment without VRD (p = 0.04, d = 0.34; p = 0.02, d = 0.44, respectively). Of the patients, 63.3% preferred VRD in the subsequent treatment. While patient preference did not correlate with sex, it correlated with age (r = -0.48, p = 0.01). CONCLUSIONS: The VRD and initiating SRP procedure with VRD affected the pain and discomfort level in anxious periodontitis patients. In addition, the anxiety level was also affected by starting the procedure with glasses.

AIM: To evaluate the effect of subgingival delivery of progranulin (PGRN)/gelatin methacryloyl (GelMA) complex as an adjunct to scaling and root planing (SRP) on an experimental periodontitis dog model with Class II furcation involvement (FI). MATERIALS AND METHODS: A Class II FI model was established, and the defects were divided into four treatment groups: (a) no treatment (control); (b) SRP; (c) SRP + GelMA; (d) SRP + PGRN/GelMA. Eight weeks after treatment, periodontal parameters were recorded, gingival crevicular fluid and gingival tissue were collected for ELISA and RT-qPCR, respectively, and mandibular tissue blocks were collected for micro computed tomography (micro-CT) scanning and hematoxylin and eosin (H&E) staining. RESULTS: The SRP + PGRN/GelMA group showed significant improvement in all periodontal parameters compared with those in the other groups. The expression of markers related to M1 macrophage and Th17 cell significantly decreased, and the expression of markers related to M2 macrophage and Treg cell significantly increased in the SRP + PGRN/GelMA group compared with those in the other groups. The volume, quality and area of new bone and the length of new cementum in the root furcation defects of the PGRN/GelMA group were significantly increased compared to those in the other groups. CONCLUSIONS: Subgingival delivery of the PGRN/GelMA complex could be a promising non-surgical adjunctive therapy for anti-inflammation, immunomodulation and periodontal regeneration.

BACKGROUND: Periodontal disease poses a significant global health challenge. Traditional treatments focus on reducing inflammation and bacterial load, yet novel approaches are continually being investigated. Recent research suggests that IL-37, a potent anti-inflammatory cytokine, may play a crucial role in modulating the inflammatory processes associated with periodontal disease. In conjunction with IL-37, low-level laser therapy (LLLT) has gained attention for its potential in promoting tissue repair, reducing inflammation, and enhancing cellular processes. This study aims to investigate the effects of LLLT on IL-37 in periodontal disease management. METHODS: Thirty patients were enrolled: the G1 group patients were treated with only scaling and root planning-SRP, the G2 group was treated with SRP and LLLT. Before treatment (T0) all periodontal probing pocket depth and bleeding on probing were obtained. Before (T0) and 10 (T1), 30 (T2) and 60 (T3) days after treatment, was achieved plaque sample and specimens of gingival crevicular fluid. Diode laser wavelength range was used between 600-1000 nm and 0.04-60 J/cm2 energy density for 3-s spotlights. RESULTS: In all patients PPD, BOP and IL-37 have shown healing improved parameters. CONCLUSIONS: Although LLLT is widely recommended for its biostimulatory and anti-inflammatory roles, it only showed additional short-term merits in reducing the pocket depth after conventional SRP. Its long-term adjunctive benefits remain unclear. Future RCTs with better study designs, adequate sample power and longer durations of follow-up are required to assess the effectiveness of LLLT as an adjunctive treatment strategy in patients with periodontal disease.

BACKGROUND: The main aim of periodontal therapy is to halt the progression of periodontitis. Curcumin, one of the main components of Curcumin longa, has been well known to possess antimicrobial, anti-inflammatory, and even anticarcinogenic properties. This systematic review assessed the impact of local application of curcumin in the pocket on the clinical and microbiologic parameters as an adjunct to scaling and root planing in periodontitis patients. METHODS: The electronic literature search retrieved 61 studies from PubMed, MEDLINE, and ScienceDirect. After screening titles, abstracts, and keywords and reading through these articles, we identified 9 articles meeting all inclusion criteria, which were included for systematic review. RESULTS: There was a significant difference in both clinical parameters in a short duration of a month after curcumin chips were placed as an adjunct to scaling and root planing as compared to the control. Local application of curcumin also results in slight to significant reduction in the red complex microorganisms. CONCLUSION: This review suggested that local application of curcumin can be considered as a viable adjunct to mechanical debridement in periodontitis. However, further studies need to be conducted to establish its optimum dose, delivery method, and frequency in achieving the best clinical outcomes.

BACKGROUND: Periodontitis is a microbially induced disease destroying structures anchoring teeth to jaw bones. Although metronidazole in combination with spiramycin is the effective conventional treatment of stage III grade C periodontitis, it has several systemic side effects. Laser therapy is widely used nowadays as an adjunct to scaling and root planing (SRP) to modulate inflammatory host response and eradicate microbes, due to bactericidal and detoxifying effects. Since microbiological analysis is one of the diagnostic methods identifying periodontal risk; our research aimed to investigate the efficacy of intra-pocket application of diode laser (980 nm) versus antibiotic therapy in enhancing clinical and microbiological parameters in stage III grade C periodontitis. METHODS: A randomized controlled clinical trial was conducted on fifty patients with stage III grade C periodontitis, divided equally into two groups. We managed test group by SRP with intra-pocket application of diode laser (980 nm) and the control group by SRP with systemic antibiotic administration (spiramycin and metronidazole). Then, we measured periodontal pocket depth (PPD) and clinical attachment loss (CAL) for both groups, before treatment (baseline), four and twelve weeks after. Moreover, we collected gingival crevicular fluid from both groups at baseline, four and twelve weeks after treatment and analyzed by real-time polymerase chain reaction to detect the relative count of Aggregatibacter actinomycetemcomitans and Porhyromonas gingivalis. RESULTS: Compared to baseline, all assessed clinical and microbiological parameters attested improvement at the end of the study period in each group individually with no significant difference between the two studied groups. Although, at twelve weeks, flare up of bacterial levels was detected with systemic antibiotic administration. CONCLUSION: Laser therapy can be considered as an effective treatment modality in stage III grade C periodontitis, avoiding the systemic antibiotic side effects and solving the recurrence problems due to bacterial resistance by long term usage.

OBJECTIVES: The present study aimed to assess and compare the effect of Morus alba and chlorhexidine gel as an adjunct to scaling and root planing (SRP) in treating stage II periodontitis. METHODS: A single-blind, randomized controlled trial was conducted on 180 patients with stage II periodontitis who received full-mouth SRP. They were randomly assigned to receive chlorhexidine digluconate (CHX) gel, Morus alba (MA) and placebo gel for Groups A, B and C, respectively, at the baseline, 15 days and 30 days. Plaque index (PI), Gingival index (GI), periodontal pocket depth (PPD) and quantitative analysis (culture) of Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis and Tannerella forsythia were assessed at baseline and 45 days. Analysis of variance was used to compare the significant difference in PI, GI, PPD and microbiological parameters between the three groups after the intervention, followed by post hoc Mann-Whitney U and Tukey's HSD test for clinical and microbiological parameters, respectively. RESULTS: Intergroup comparison of the PI, GI and microbiological parameters between the MA and CHX groups at the end of 45 days did not show a statistically significant difference (p > 0.05), whereas a statistically significant difference was observed for PPD between MA and CHX groups with the mean difference of 0.18 mm (p = 0.002). CONCLUSION: Morus alba gel was found to be effective in decreasing PPD. However, there was no difference between Morus alba and chlorhexidine gel as an adjunct to SRP in treating stage II periodontitis.

OBJECTIVES: To compare the effects of powered and manual toothbrushing following scaling and root planing on bleeding on probing and other clinical indicators of periodontitis. MATERIALS AND METHODS: This was a randomized, examiner-blind, parallel-design, 24-week clinical study. Eligible subjects were 18-75 years of age with Stage I or II periodontitis. All subjects received scaling and root planing (SRP) within 28 days of enrollment. Thereafter, subjects were randomized to twice daily at-home use of either a powered toothbrush (PTB) or a manual toothbrush (MTB). Randomization was balanced for gender and periodontitis stage. No other oral hygiene aids were permitted. Subjects were evaluated every 4 weeks for the following measures: bleeding on probing (BOP), surface plaque (MPI), probing pocket depth (PPD) and clinical attachment level until Week 24. RESULTS: Of 328 randomized subjects, 299 subjects completed the study. For BOP at Week 24, the Least Squares (LS) Mean, standard error (SE) reduction from baseline was 0.24 (0.01) for the PTB group and 0.02 (0.01) for the MTB group, resulting in a statistically significant treatment difference of 0.22 (0.01), p-value < 0.0001. There were also concomitant reductions in MPI and PPD at Week 24, resulting in statistically significant (p-value < 0.0001) LS Mean (SE) treatment differences of 0.86 (0.04) and 0.24 (0.01), for MPI and PPD, respectively. CONCLUSION: When combined with SRP, daily home oral hygiene maintenance including a powered toothbrush significantly reduced clinical symptoms of periodontitis and surface plaque levels compared to a manual toothbrush in a Stage I/II periodontitis population.

BACKGROUND: This study aimed to compare the efficacy of three different techniques, namely virtual simulation technology (VS), traditional pathological typodont (TT), and quail egg (QE), in pre-clinical training of periodontal ultrasonic scaling. It also aimed to propose an integrated teaching approach for ultrasonic scaling teaching. METHODS: This single-blind randomized multi-arm trial enrolled 108 fourth-year students from Guanghua School of Stomatology at Sun Yat-sen University. The participants were randomly, evenly assigned to VS, TT, or QE group. First, the participants received theoretical review on ultrasonic scaling and demonstrative teaching. Then in the 90-minute operation training by group, students used traditional typodont equipped in head-simulators, raw quail eggs, or scaling module of the UniDental VS system respectively. Then all participants practiced on pathological models for 30 min. In the final operation examination, participants were instructed to remove the supra- and sub-gingival calculi pre-set on designated teeth by ultrasonic scalers within 30 min. Their performances were evaluated by residual calculus rate and a multi-perspective scoring scale. After the examination, questionnaires were provided to assess the teaching effects of each method and the fidelity of VS. Statistical analysis was carried out using one-way, two-way ANOVA, and multiple t-test. RESULTS: Students in VS group had significant higher total test scores than QE group (87.89 ± 6.81, 83.53 ± 8.14) and TT group (85.03 ± 6.81). VS group scored higher in several dimensional comparisons with the other two groups, especially in difficult situations. QE group had higher scores particularly in force application and supra-gingival scaling. TT group scored the highest in pivot stability practice and body position training. Students gave higher scores when assessing the fidelity of VS than experienced teachers. CONCLUSION: The study highlights the importance of specialized pre-clinical training on ultrasonic scaling for dental students. The methods adopted in current study (VS, TT and QE) each offered unique advantages in education, which can be combined to create an integrative teaching procedure. This procedure aims to provide an effective, advisable and normative pre-clinical training procedure for ultrasonic scaling. By utilizing the strengths of each method, dental educators can deliver high-quality training and ensure that students are well-prepared for clinical practice.

DESIGN: The paper by Kubberød et al. is a single-centre, double-blinded, prospective randomised control trial, comparing the radiographic alveolar bone levels in patients with periodontal disease following different treatment protocols over a 5-year period. In total, 184 patient were recruited to the study, and 161 (87.5%) of the patients returned for follow up over a 5-year period. The patients underwent a 3-month, pre-treatment oral hygiene phase before being randomised to one of 4 treatment regimens: (i) same day full mouth disinfection + adjunctive metronidazole; (ii) same day full mouth disinfection + placebo; (iii) scaling and root planing + adjunctive metronidazole; (iv) scaling and root planing + placebo. Scaling and root planing was carried out over a period of 2 to 4 weeks. The participants were enroled in maintenance treatment at 3, 6 and 12 months, then bi-annually for 5 years following active treatment. Radiographic recordings were taken at baseline pre-treatment and then at the 5-year follow up examination. Clinical periodontal measurements such as plaque/bleeding scores, and PPD/CAL (in mm) were also recorded pre/post-treatment. CASE SELECTION: Participants for this study were recruited over 2 years from referrals to a specialist periodontal clinic in Norway. The patients were aged between 35-75 and at the time of inclusion into the trial, had no systemic conditions relevant to periodontitis. The participants underwent a 3-month pre-treatment oral hygiene phase to attempt to reduce the risk of false pocketing at the initial baseline measurements. For inclusion into the trial, participants were required to have more than 5 persistent sites of PPD > 5 mm, and < 15% plaque sites following the pre-treatment hygiene regime. Participants were also only eligible if there were no known reactions to metronidazole or known to carry microorganisms resistant to metronidazole. DATA ANALYSIS: Bland-Altman plots were used to allow for assessment of the reproducibility of the radiographic measurement carried out for the examiner assessing the radiographs. Linear regression was used to describe the degree of bone loss noted over the 5-year period. RESULTS: Firstly, the authors describe the radiographic examiners results from the Bland-Altman plots, which shows the examiner to have an error range of -0.04 to 0.01 mm in 95% of cases with the error intervals (-0.47,0.40), (-0.60,0.54) and (-0.55,0.56). Secondly, the authors present the number of periodontal pocket sites (interproximal) examined at the base and at the 5-year follow up. The average number of sites with readings for RBL, CAL and PPD at base line averaged from 41.2 and 43.7 depending on the treatment arm. This was lower at the 5-year follow up, between 30.2 and 36.9. The number of sites with no data (indicating loss of tooth) also increased from baseline to the 5-year follow up, from 4 to 13. Lastly, the results show the change in RBL, CAL and PPD from baseline to 5-year follow up, post-treatment for all 4 treatment protocols. This shows that metronidazole in conjunction with mechanical debridement has a small but statistically insignificant positive effect on RBL and CAL gain. Full mouth disinfection was found to result in less reduction in PPD compared with scaling and root planing; however, this was also found to be statistically insignificant. CONCLUSIONS: Regardless of the treatment protocol, all patients demonstrated a reduction in PPD. The FDIS+MTZ group had no statistically significant change in the RBL. However, the other treatment regimens showed overall bone loss over the 5-year period, which again is statistically unimportant. Overall, the authors conclude that resolution of periodontitis induced inflammation is better observed through clinical measurements of the soft tissues, such as PPD and CAL, versus radiographic examination. This was particularly evident as the discrepancies between RBL and CAL were largest for shallower PPDs.

Class IV dental diode lasers have been introduced as a nonsurgical therapy for periodontal pockets in veterinary and human dentistry. This retrospective case series evaluates the use of Class IV dental diode laser therapy for abnormal periodontal pockets in a specialty veterinary dental practice. A hypothesis that the Class IV diode dental laser is a useful adjuvant modality in canine periodontal pocket therapy in the reduction of clinical pocket depth was made. This article discusses and demonstrates diode laser use in periodontal pocket therapy in a specialty veterinary dental practice and reviews the current literature. Inclusion in this study was limited to client-owned dogs with noted periodontal pocketing on any tooth type between 3 and 6 mm, which were treated with closed root planing (RP/C) and laser therapy who returned in 6 to 7 months for recheck of the pockets from the years 2017 to 2020. Twelve patients met the inclusion criteria. A total of 128 periodontal pockets were included in the study. Each periodontal pocket was a case receiving therapy. The mean periodontal pocket depth before the treatment is measured as 3.35 mm. The mean pocket depth of the periodontal pockets following treatment was 0.59 mm. The mean improvement in periodontal pocket depths after diode laser therapy when considering patient and tooth number using linear mixed-effects modeling was 2.63 mm (95% confidence interval [CI]: 1.81-3.46, P < .0001). No statistically significant results were observed for pocket type, as P values were greater than .05.

OBJECTIVES: To systematically evaluate randomised controlled trials (RCTs) on whether adjuvant application of antimicrobial photodynamic therapy (aPDT) through the technique of irradiation in the external region of the periodontal pocket with optic-fibre tip offers benefits to scaling and root planning (SRP). METHODS: Five databases were searched by two independent reviewers according to pre-specified eligibility criteria up to April 2023. No restrictions regarding date of publication, language and minimum follow-up period were imposed. The Cochrane Collaboration's Risk of Bias tool (RoB 2.0) was used for quality appraisal and Grading of Recommendations, Assessment, Development and Evaluation for assessing the certainty of evidence. RESULTS: A total of 1388 publications were identified and reviewed for eligibility. Four of them fulfilled the inclusion criteria. The sample consisted of a total of 83 patients with periodontitis. In these, 330 periodontal sites were evaluated. The clinical findings of the majority of the included studies demonstrated that patients who received the association of aPDT + RAR with the protocol evaluated here, obtained clinical results similar to patients who received only the SRP alone. In none of the evaluated RCTs, clinical advantages were observed that would categorise this aPDT protocol as superior to conventional treatment. CONCLUSION: Applying aPDT after SRP with external irradiation of the periodontal pocket does not seem to result in any clinical benefit compared to the use of SRP alone in patients with periodontitis.

BACKGROUND: Virtual simulation (VS) technology has been widely utilised in various aspects of oral education. This study aimed to evaluate the impact of VS technology in a scaling and root planing (SRP) teaching programme and explore an effective teaching approach. METHOD: A total of 98 fourth-year undergraduates from Guanghua School of Stomatology at Sun Yat-sen University were enrolled in this study and randomly assigned to either the VS teaching group or the traditional teaching (TT) group. All participants received SRP training before undergoing an operational examination. Subsequently, questionnaires were administered to both students and teachers involved in the programme to assess the teaching effect and fidelity of the VS training system. Unpaired Student t test was used to analyse the final test scores and residual rates amongst students. RESULTS: The overall residual rate of the calculus in the VS group was significantly lower than that in the TT group (48.81% ± 13.50% vs 56.89% ± 13.68%, P<.01). The difference was particularly notable in posterior teeth, proximal surfaces, and deep pockets. Additionally, the VS group students achieved higher final grades compared to the TT group (86.92 ± 6.10 vs 83.02 ± 6.05, P<0.01). In terms of teaching effectiveness assessment, the VS group students provided higher scores than the TT group, except in the areas of mastery of position, finger rests, and efficiency. CONCLUSIONS: The implementation of VS technology demonstrated improvements in students' performance in SRP teaching. Therefore, a novel integrated pedagogic approaches method that combines VS technology with traditional teaching approaches could be further explored in future training programmes.
