RESUMEN
Plaque-induced gingivitis is an inflammatory response in gingival tissues resulting from bacterial plaque accumulation at the gingival margin. Postbiotics can promote the proliferation of beneficial bacteria and optimise the state of microbiota in the oral cavity. In this study, we investigated the effect of inactivated Lacticaseibacillus paracasei Probio-01 on plaque-induced gingivitis and the dental plaque microbiota. A total of 32 healthy gingival participants (Group N, using blank toothpaste for 3 months) and 60 patients with plaque-induced gingivitis (30 in Group F, using inactivated Probio-01 toothpaste for 3 months, and 30 in Group B, using blank toothpaste for 3 months, respectively) were recruited. Clinical indices, which included bleeding on probing (BOP), gingival index (GI), and plaque index (PI), were used to assess the severity of gingivitis. Furthermore, 16SrDNA amplicon sequencing was used to explore changes in the gingival state and dental plaque microbiota in patients with plaque-induced gingivitis. The results showed that inactivated Probio-01 significantly reduced clinical indices of gingivitis, including BOP, GI, and PI, in participants with plaque-induced gingivitis and effectively relieved gingival inflammation, compared with that observed in the control group (group B). Inactivated Probio-01 did not significantly influence the diversity of dental plaque microbiota, but increased the relative abundance of dental plaque core bacteria, such as Leptotrichia and Fusobacterium (P < 0.05). Strong correlations were observed between the indices and abundance of dental plaque microbiota. Overall, the inactivated Probio-01 significantly reduced the clinical indices of gingivitis and effectively improved gingival inflammation in patients with plaque-induced gingivitis. The activity of inactivated Probio-01 against plaque-induced gingivitis was possibly mediated by its ability to regulate the dental plaque microbiota, as indicated by the close correlation between the plaque microbiota and clinical indices of gingivitis.

OBJECTIVE: This study was performed to estimate the effectiveness of novel oral hygiene instruction (OHI) focusing on areas with deep periodontal pockets for reduction of periodontal inflammation. BACKGROUND DATA DISCUSSING THE PRESENT STATUS OF THE FIELD: Because stained areas on the plaque chart do not always correspond to the areas with deep periodontal pockets, conventional OHI based on O'Leary's plaque control record (PCR) often provides guidance inconsistent with the target area. METHODS: This randomized clinical trial involved two groups: (1) OHI based on the PCR limited in deep pocket sites (novel OHI group) and (2) OHI based on O'Leary's PCR (conventional OHI group). The unique PCR (aggressive target for PCR [agPCR]; only counting the plaque-stained areas with PD at ≥4 mm sites) for the novel OHI was calculate by dedicated expression program. The probing depth (PD), bleeding on probing (BOP), and periodontal inflamed surface area (PISA) were obtained at the baseline and 5 to 6 months later. RESULTS: The approximation curve with PISA before and after instruction indicated that the PISA converged to a lower value after instruction in the novel OHI group. The approximation curve with the improvement rate of the PISA and agPCR showed a positive correlation in the novel OHI group but no correlation in the conventional OHI group. CONCLUSION: Control of inflammation was more effective in the novel OHI group. These results suggest that this novel OHI technique using our developed application could be used as a strategy to improve the effectiveness of brushing instruction.

BACKGROUND: Periodontitis is characterized by local inflammatory conditions in the periodontium, its severe form has been associated with elevated systemic inflammatory markers. However, the long-term effects of periodontal inflammation control on systemic inflammatory markers are unclear. OBJECTIVE: This study aimed to investigate the long-term effects of periodontal therapy on the levels of peripheral venous blood inflammatory markers in patients with generalized aggressive periodontitis (GAgP), all of whom were now diagnosed as Stage III or IV Grade C periodontitis. METHODS: Patients with GAgP were consecutively recruited from April 2013 to August 2014 (T0). Active periodontal treatment (APT) was provided, and follow-ups were conducted over a 3- to 5-year period (T1). Clinical parameters were assessed and fasting venous blood was collected at T0 and T1. Complete blood cell counts were obtained, and biochemical analyses were performed to evaluate the levels of serum components. The correlations between probing depth (PD) and hematological parameters were analyzed. RESULTS: A total of 49 patients with GAgP completed APT and follow-ups. Probing depth (PD) reduced from 5.10 ± 1.07 mm at T0 to 3.15 ± 0.65 mm at T1. For every 1-mm reduction in PD after treatment, the neutrophil count, neutrophil-lymphocyte ratio, and total protein concentration were reduced by 0.33 × 109/L, 0.26, and 1.18 g/L, respectively. In contrast, the albumin/globulin ratio increased by 0.10. CONCLUSION: This study indicated that periodontal therapy may have beneficial effects on peripheral venous blood inflammatory markers in patients with GAgP during long-term observation.

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.

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.

AIM: To evaluate site-related changes in periodontal pocket depth (PPD) after non-surgical periodontal therapy and to identify predictors for PPD changes in a retrospective patient data analysis. MATERIALS AND METHODS: PPD, clinical attachment level, bleeding on probing, tooth mobility (TM), furcation involvement (FI), abutment status, adherence to supportive periodontal care (SPC) and SPC follow-ups were obtained from fully documented patient data before periodontal therapy (baseline, T0), after active periodontal therapy (APT, T1) and during SPC (T2). PPD changes were classified into deteriorated or unchanged/improved at the site level. Multi-level logistic regression analysis was performed to identify factors influencing PPD changes during SPC. RESULTS: This retrospective study included 51 females and 65 males (mean T0 age: 54.8 ± 10.1 years, 25 smokers, 12 diabetics) suffering from Stage III/IV periodontitis. Evaluation outcome: T0/16,044 sampling sites/2674 teeth; T1/15,636/2606; T2/14,754/2459. During 9.0 ± 2.3 years SPC, PPD decreased (-1.33 ± 0.70 mm) by 21.8% of the sites, remained unchanged by 41.4% and increased (1.40 ± 0.78 mm) by 36.8%. Distopalatal FI (p < .001, odds ratio [OR]: 0.252, 95% confidence interval [CI] for OR: 0.118-0.540), residual pockets (p < .001, OR: 0.503, 95% CI: 0.429-0.590) and TM Degrees I-III (Degree I: p = .002, OR: 0.765, 95% CI: 0.646-0.905; Degree II: p = .006, OR: 0.658, 95% CI: 0.489-0.886; Degree III: p = .023, OR: 0.398, 95% CI: 0.180-0.879) correlated significantly with increasing PPD. CONCLUSIONS: Over 75% of PPD remained unchanged or increased during SPC. Distopalatal FI, TM Degrees I-III and residual pockets after APT lead to worsening of periodontal pockets.

AIM: To examine the association of dietary patterns with periodontal disease (PD) and its progression over 5 years. MATERIALS AND METHODS: Analyses involved 1197 post-menopausal women from the OsteoPerio cohort. Dietary patterns assessed include Healthy Eating Index-2015 (HEI), Alternative HEI (AHEI), Dietary Approaches to Stop Hypertension (DASH) and alternate Mediterranean Diet (aMed) at baseline (the average of two food frequency questionnaires administered between 1993 and 2001). At baseline and the 5-year follow-up, periodontal assessments evaluated alveolar crestal height (ACH), probing pocket depth (PPD), clinical attachment loss (CAL), percentage of gingival sites bleeding on probing (%BOP) and missing teeth due to PD. Linear and logistic regression were used to examine the associations. RESULTS: Cross-sectionally, HEI and aMed were associated with smaller CAL and %BOP; along with DASH, they were associated with a decreased odds of teeth missing due to PD. AHEI and aMed were associated with a decreased odds of severe PD. Prospectively, AHEI was associated with greater ACH progression. This association was attenuated to the null after loss of ACH was imputed for teeth lost due to PD over follow-up, or after excluding participants with diabetes, osteoporosis, hypertension or heart disease at baseline. CONCLUSIONS: Better adherence to healthy dietary patterns was associated with better PD measures cross-sectionally but greater progression of ACH over 5 years. The latter might be explained by incident tooth loss due to PD and pre-existing comorbidities.

AIM: This study aimed to compare microbial and inflammatory profiles in periodontally/systemically healthy African American (AA) and Caucasian (C) individuals. MATERIALS AND METHODS: Thirty-seven C and 46 AA aged from 5 to 25 years were evaluated regarding periodontal disease, caries, microbial subgingival profile via 16-s sequencing, as well as salivary and gingival crevicular fluid (GCF) inflammatory profile via multiplex assay. RESULTS: Greater probing depth percentage was detected in AA (p = .0075), while a higher percentage of caries index (p = .0069) and decayed, missing, filled teeth (DMFT) index (p = .0089) was observed in C, after adjusting for number of teeth, sex and age. Salivary levels of IL-6, IL-8 and TNFα were higher for C, whereas GCF levels of eotaxin, IL-12p40, IL-12p70, IL-2 and MIP-1α were higher in AA (p < .05). Different microbial profiles were observed between the races (p = .02). AA presented higher abundance of periodontopathogens (such as Tanerella forsythia, Treponema denticola, Filifactor alocis, among others), and C presented more caries-associated bacteria (such as Streptococcus mutans and Prevotella species). Bacillaceae and Lactobacillus species were associated with higher DMFT index, whereas Fusobacterium and Tanerella species with periodontal disease parameters. CONCLUSIONS: A different inflammatory and bacterial profile was observed between healthy AA and C, which may predispose these races to higher susceptibility to specific oral diseases.

AIM: Cellular oxygen sensing mechanisms have been linked to periodontal condition, and levels of haemoglobin (Hb) (the main carrier of oxygen) can be used as a surrogate measure for hypoxia. We aimed to examine relations between Hb levels and key periodontal health parameters in a general population. MATERIALS AND METHODS: The population comprised 1711 (47% male) subjects from the Northern Finland Birth Cohort 1966, for whom an oral health examination was carried out at 46 years of age and whose Hb levels were within the Finnish reference values. Relative risks (RRs) were estimated using Poisson regression models. RESULTS: The low-Hb tertile (mean Hb 133 g/L) had healthier anthropometric, metabolic and periodontal health parameters than the high-Hb tertile (mean Hb 151 g/L). Multivariable regression models adjusted for risk factors showed Hb levels to be positively associated with alveolar bone loss (ABL) and periodontal pocket depth (PPD), although the associations were weaker after adjustment for key metabolic parameters and were strongly influenced by smoking status. CONCLUSIONS: Hb levels within the normal variation are positively associated with PPD and ABL. The association between Hb levels and periodontal condition appeared to be more complex than had previously been anticipated.

AIM: The oral microenvironment contributes to microbial composition and immune equilibrium. It is considered to be influenced by dietary habits. Phenylketonuria (PKU) patients, who follow a lifelong low-protein diet, exhibit higher prevalence of oral diseases such as periodontitis, offering a suitable model to explore the interplay between diet, oral microbiota and oral health. MATERIALS AND METHODS: We conducted 16S rDNA sequencing on saliva and subgingival plaque from 109 PKU patients (ages 6-68 years) and 114 age-matched controls and correlated oral microbial composition and dental health. RESULTS: PKU patients exhibited worse dental health, reduced oral microbial diversity and a difference in the abundance of specific taxa, especially Actinobacteriota species, compared to controls. PKU patients with poor periodontal health exhibited higher alpha diversity than the orally healthy ones, marked by high abundance of the genus Tannerella. Notably, the observed taxonomic differences in PKU patients with normal indices of decayed/missing/filled teeth, plaque control record, gingival bleeding index and periodontal screening and recording index generally differed from microbial signatures of periodontitis. CONCLUSIONS: PKU patients' reduced microbial diversity may be due to their diet's metabolic challenges disrupting microbial and immune balance, thus increasing oral inflammation. Higher alpha diversity in PKU patients with oral inflammation is likely related to expanded microbial niches.

AIM: This study aimed to investigate the effects of diabetes care on periodontal inflammation. MATERIALS AND METHODS: This prospective cohort study included 51 Japanese patients with type 2 diabetes who underwent intensive diabetes care including educational hospitalization and regular outpatient treatment for 6 months. Dental prophylaxis without subgingival scaling was provided three times during the observational period. Associations between changes in periodontal parameters and glycaemic control levels were evaluated using multiple regression analysis. RESULTS: Overall, 33 participants (mean age: 58.7 ± 12.9) were followed up for 6 months. At baseline examination, 82% were diagnosed with Stage III or IV periodontitis. Haemoglobin A1c (HbA1c) level changed from 9.6 ± 1.8% at baseline to 7.4 ± 1.3% at 6 months. The ratio of probing pocket depth (PPD) ≥4 mm, bleeding on probing (BOP), full-mouth plaque control record (PCR), periodontal epithelial surface area (PESA) and periodontal inflamed surface area (PISA) also significantly improved. The reduction in PPD and PESA was significantly associated with changes in both HbA1c and fasting plasma glucose (FPG) levels, and the reduction in PISA was significantly associated with an improvement in FPG after adjusting for smoking, change in body mass index and full-mouth PCR. CONCLUSIONS: This is the first study to report a significant improvement in PPD and BOP after intensive diabetes care and dental prophylaxis without subgingival scaling.

OBJECTIVE: The aim of this study was to evaluate the long-term (5 years) clinical efficacy of the one-abutment one-time protocol (test) versus the standard of care by placing the definitive abutment on the day of the prosthetic delivery (control). MATERIALS AND METHODS: In this study, 39 subjects with 60 implants were randomly allocated to either the test or the control group. Changes in the radiographic interproximal bone levels (DIB), modified sulcus bleeding index, probing depth, modified plaque index, papilla fill (Jemt score), incidence of peri-implantitis and peri-implant mucositis as well as patient-reported outcomes measures (PROMs) were collected and compared at 1, 3 and 5 years. RESULTS: At 5 years, the control group showed a greater, although not statistically significant, change in mean DIB values (0.97 mm vs. 0.53 mm). Regarding the other clinical parameters evaluated, no statistically significant differences were observed between groups at any time point. At 5 years, 51% of the implants presented peri-implant mucositis (25.5% in the control and 23.5% in the test), and only one implant in the test group developed peri-implantitis. CONCLUSIONS: The connection and disconnection of healing abutments during the healing period was not associated with higher long-term bone loss. Clinical outcomes and PROMs were similar between groups.

BACKGROUND Regularly removing dental plaque is key to good oral hygiene and gingival health promotion. This study aimed to compare the effects of using soft and medium toothbrushes using the plaque index (PI), gingival index (GI), and bleeding on probing (BOP) index. MATERIAL AND METHODS A randomized parallel-group study design was used. Sixty-four participants were randomly assigned to 2 similar intervention groups (medium and soft toothbrush groups). The PI, GI, and BOP indexes were used. The median and median difference of PI, GI, and BOP were calculated. SPSS was used for data entry and analysis. Wilcoxon and Mann-Whitney U tests were used for data analysis. RESULTS The median scores of GI, PI, and BOP significantly decreased from 1.8, 1.7, and 2.0, respectively, before using medium toothbrushes to 0.0, 0.1, and 0.0, respectively, after using medium toothbrushes (all P<0.0001). Similarly, the median scores of GI, PI, and BOP significantly decreased from 2.0, 1.7, and 2.0, respectively, before using soft toothbrushes to 1.1, 0.9, and 1.0, respectively, after using soft toothbrushes (P<0.0001). The median differences in GI, PI, and BOP scores among those using medium toothbrushes were higher than the median differences among those using soft toothbrushes [(1.8 vs 0.9), (1.6 vs 0.8), and (2.0 vs 1.0), respectively]. These differences were statistically significant (P<0.0001). CONCLUSIONS This study concludes that medium and soft toothbrushes were effective in removing plaque and controlling gingivitis. Medium toothbrushes were more effective than soft toothbrushes in achieving these outcomes.

INTRODUCTION: Proper tooth brushing is a complicated process for children. Therefore, the aim of this study was to investigate the effect of differential learning to improve tooth brushing in children. METHODS: In this prospective, controlled, single-blinded, randomized clinical trial, 58 children between 3 and 8 years of age (mean: 5.7 ± 1.5 years; 29 female) were randomly assigned to test or control group through the child's self-drawing of an unlabeled envelope from a box. All children received oral hygiene instructions and information in these sealed envelopes and were asked to follow the corresponding instructions at home for 28 days. Children in the test group received instructions with exercises using the differential learning method, whereas the children in the control group received the usual tooth brushing instructions. RESULTS: At baseline and planned follow-ups after 4 and 12 weeks, plaque and gingival indices (QHI, PBI) were recorded in both groups by 2 calibrated and blinded investigators. At baseline, there were no significant differences between the test and control groups regarding plaque and gingival indices (QHI: 4.1 ± 0.5 vs. 4.1 ± 0.4; p = 0.7; PBI: 0.6 ± 0.3 vs. 0.6 ± 0.3; p = 0.7). At the 1st and 2nd follow-up, both groups showed improved oral health indices, but there was an overall better improvement in the test group. While the difference in gingival indices was statistically significant in the 1st recall (PBI/test: 0.1 ± 0.2 vs. control: 0.3 ± 0.2; p < 0.001), the difference in plaque indices was not (QHI/test: 2.1 ± 0.9; control: 2.6 ± 0.9; p = 0.07). At the 2nd recall (mean week = 19.5 weeks), the test group showed statistically significant and clinically relevant better oral health indices than the control group (2nd recall, QHI/test: 2.1 ± 0.9 vs. control: 3.2 ± 1; p < 0.001; PBI/test: 0.1 ± 0.2 vs. control: 0.5 ± 0.2; p < 0.001). CONCLUSION: In conclusion, differential learning leads to oral hygiene improvement in children with high caries risk and initially poor oral hygiene, which was superior to the conventional learning method through repetition in the medium term.

OBJECTIVES: Several systematic reviews and meta-analyses have reported positive relationships between erectile dysfunction (ED) and periodontal disease. However, no study has evaluated the relationships of occlusal support status and the number of remaining teeth with ED. The aim of the present study was to investigate the relationships between ED and the remaining teeth number, periodontal disease, and occlusal support status. METHODS: This study included 400 community-dwelling men. Periodontal health status and occlusal support condition were evaluated using the Community Periodontal Index (CPI) and Eichner classification. Multivariable analyses were performed to evaluate the relationships between ED and the remaining teeth number, periodontal disease, and occlusal support status. RESULTS: The median age was 53 years. Of the 400 men, 333 (83%) were classified into ED group. In univariable analyses, remaining teeth number, CPI score, and Eichner classification were significantly associated with ED. In multivariable analyses, the remaining teeth number (odds ratio [OR]: 0.907, p = 0.114) and CPI score (OR: 0.978, p = 0.864) were not significantly associated with ED, whereas the Eichner classification was independently and significantly associated with ED (OR: 3.490, p = 0.042). CONCLUSIONS: Poor occlusal support status was significantly associated with ED in community-dwelling men, as opposed to remaining teeth number and periodontal health status.

AIM: The aim of this study was to investigate the role of pyridoxal-5-phosphate (PLP) level on the oral health status as a predictive marker in patients with hypophosphatasia (HPP). MATERIALS AND METHODS: Throughout a systematic retrospective assessment both bone metabolism and oral health status were analyzed. The oral health status was assessed by the decayed/missing/filled teeth index (DMFT), clinical attachment level (CAL), probing pocket depth (PPD), and the periodontal screening index (PSI). RESULTS: A total of 48 HPP patients (81.3% female) with a mean age of 42.21 years was included in this retrospective study. The study population was divided into two groups using the mean PLP level (87 µg/l) as a cut-off. Patients with a PLP level ≥ 87 µg/l (n = 14) showed a significantly poorer oral health status regarding DMFT index, CAL, PPD and PSI compared to patients with a PLP level < 87 µg/l (n = 34). No significant group differences for tooth loss were found. CONCLUSION: The results of the present study indicate that the PLP level is a suitable diagnostic predictor for the oral health status in HPP patients. HPP patients with PLP levels ≥ 70 µg/l should be included into a regular dental preventive program. CLINICAL RELEVANCE: The oral health status in HPP and its correlation with laboratory parameters (i.e. PLP) has been understudied. For clinical practice, the findings of the present study clearly demonstrated that high PLP levels correlate with a worse oral health status in HPP patients. Therefore, these patients should receive an intensive dental treatment and/or inclusion in a strict maintenance program in a specialized dental practice/university hospital with a PLP level ≥ 70 µg/l.

OBJECTIVE: To compare between lower permanent retainers placed in the middle of the incisal third and retainers placed in the middle of lower incisors in terms of gingival condition, lower incisors stability and retainers' failure rate. MATERIALS AND METHODS: This is a split-mouth clinical trial. Fifty patients finished fixed orthodontic treatment and required fixed permanent retainer in the lower arch were recruited. A multistranded (0.0215 inch) retainer, with a vertical step in the midline placing half of the retainer in the incisal third and the other half in the middle of the lower incisors was attached to all the teeth in the lower labial segment. After one year, all the subjects were recalled. The primary outcome was to evaluate the plaque index (PI) and the gingival index (GI) of the lower labial segment teeth. The secondary outcome was to assess retainers' failure rate and the relapse in lower labial segment alignment. RESULTS: The GI and the PI scores were significantly smaller on the side where the retainer was placed incisally (P = 0.004, P < 0.001, respectively). There was no statistical difference in the average Irregularity Index (IRI) and the retainer's failure rate between the two sides (P = 0.52, P = 0.76, respectively). CONCLUSION: Placing lower fixed retainers in the incisal third will improve the lower labial segment oral hygiene and gingival health in the lingual area without affecting the efficiency or the integrity of the retainers. This trial was not registered Null Hypothesis: Placing the lower permanent retainer in the middle of the lingual surfaces of the lower labial segment' teeth or in the incisal third will not affect the gingival health of the lower incisors.

OBJECTIVES: This study aimed to explore the relationship between Radiographic Residual Vertical Defects (RVDs) and the progression of periodontitis in patients undergoing periodontal maintenance therapy (PMT). MATERIALS AND METHODS: Teeth with RVDs were compared to the same contralateral teeth in the same patient. The study investigated the effect of smoking, diabetes, compliance, disease Stage, and Grade, baseline probing depth (PD), periodontal risk score (PRS), baseline pocket closure (PC) (≤ 4 mm), and tooth mobility on disease progression. We calculated the need for retreatment during PMT and its associated cost. Generalized estimation equations and linear and multilevel logistic regression analyses were employed for data analysis. RESULTS: Each group had 139 teeth, accounting for 80 patients. Although the group with RVDs had similar PD reduction compared to the control teeth, the prevalence of PC at the last follow-up was reduced to half in the RVDs group (odds ratio OR = 0.5; p-value = 0.028), regardless of PC status at the baseline. RVDs were also significant predictors of tooth loss due to periodontitis (TLP), with an OR of 2.28 (p = 0.043). Patients with diabetes, Stage IV, higher mobility, and higher PRS scores had a higher risk of tooth loss due to periodontitis (OR = 4.71, 3.84, 3.64, and 5.97, respectively (P < 0.01). Incidences of sites requiring retreatment were similar in both groups, but the cost of treatment was 30% higher for teeth with RVDs. Grade C had the most significant influence on receiving retreatments (OR = 18.8, p = 0.005). CONCLUSION: Teeth with RVDs represent a risk indicator for tooth loss compared to identical contralateral teeth with similar PD in the same patient. Teeth with RVD had more risk of pocket opening during follow-up. CLINICAL RELEVANCE: While teeth with RVDs can be maintained long-term, they have twice the risk of pocket opening and tooth loss due to periodontitis during follow-up. Patients with systemic and local risk factors need to be monitored closely as they are at the highest risk of losing teeth with RVDs. The increased cost of retreatment for teeth with RVDs also has implications in terms of retention versus extraction and replacement.

OBJECTIVES: To compare periodontal parameters of splinted posterior teeth versus control teeth over ten years of supportive periodontal therapy (SPT) and to assess the survival rate of splints. MATERIAL AND METHODS: Retrospective data of 372 SPT-patients was screened for splints (composite/fiberglass-reinforced composite) in the posterior (molars/premolars) which were inserted at least ten years before due to increased tooth mobility. For each splinted tooth (test), a corresponding control tooth had to be present at the first SPT-session after splint insertion (T1). Data was assessed at T1 and ten years later (T2). Possible influencing covariates for splint survival (mobility degree/Eichner class) were tested by Cox regression. The change in clinical attachment level (ΔCAL), probing pocket depth (ΔPPD) and the testing of possible influencing covariates was analyzed by using mixed linear regression. RESULTS: Twenty-four patients (32 splints, 58 splinted teeth) were included. Ten test and two control teeth were lost. No differences were observed between ΔCAL and ΔPPD of test teeth compared to control teeth (ΔCAL -0.38 ± 1.90 vs. 0.20 ± 1.27 mm; ΔPPD -0.17 ± 1.18 vs. 0.10 ± 1.05 mm). Twenty-two splints fractured during the observation period (survival-rate: 31%). Mobility degree and Eichner class did not influence time until fracture. CONCLUSIONS: Splinting of periodontally compromised and mobile posterior teeth does not have any disadvantage regarding the clinical periodontal situation when regular SPT is applied. However, splint fractures occur very often. CLINICAL RELEVANCE: Splinting of posterior teeth is a treatment option in addition to active periodontal therapy when patients are disturbed by tooth mobility but splints have a high susceptibility to fracture.

OBJECTIVE: To investigate the capability of periodontal grading to estimate the progression of periodontal disease and the responsiveness to therapy. MATERIALS AND METHODS: Eighty-four patients who underwent non-surgical therapy (NST) were included. Direct and indirect evidence of progression were determined according to the current classification. Responsiveness to therapy was examined using mean pocket probing depths reduction (PPDRed), reduction of bleeding on probing (BOPRed), and the rate of pocket closure (%PC) after six months. RESULTS: Statistical analysis revealed no agreement between direct and indirect evidence in grading periodontitis (κ = 0.070). The actual rate of progression as determined by longitudinal data was underestimated in 13% (n = 11), overestimated in 51% (n = 43) and correctly estimated in 30% (n = 36) by indirect evidence. No significant differences in responsiveness to therapy were observed in patients graded according to direct evidence. Using indirect evidence, patients assigned grade C showed more PPDRed but less BOPRed and lower %PC compared to grade B. CONCLUSION: The present data indicate that indirect evidence may lead to inaccuracies compared to direct evidence regarding the estimation of periodontal progression. However, indirect evidence seems to be more suitable in the estimation of responsiveness to therapy than direct evidence, helping to identify cases that are more likely to require additional therapies such as re-instrumentation or periodontal surgery. CLINICAL RELEVANCE: Regarding the estimation of disease progression and responsiveness to periodontal therapy, accuracy and reliability of both direct and indirect evidence are limited when grading periodontitis.
