Background
The aim of this study was to evaluate the incidence of preloading crestal bone loss (PLCBL) and to identify the patient-related and implant-related factors associated with PLCBL.
Methods
This retrospective cohort examined the dental records of patients who received at least one dental implant. PLCBL was defined as a reduction ⩾0.5 mm and severe PLCBL (primary variable) as a reduction ⩾1.5 mm in mesial and/or distal bone level, measured from the day of implant placement to uncovering or abutment installation/crown delivery. The incidence of PLCBL and patient and implant variables were recorded. Bivariate analysis and binary logistic regression identified factors associated with PLCBL ⩾0.5 mm and ⩾1.5 mm.
Results
A total of 746 dental implants placed in 361 patients from January 2011 to July 2021 was included in the analyses. Of the implants assessed, 24.4% (n = 182) exhibited PLCBL ⩾ 0.5 mm and 10.5% (n = 78) presented severe PLCBL (i.e., ⩾1.5 mm). Males (odds ratio [OR] = 1.85, 95% confidence interval [CI] = 1.11–3.07), patients with diabetes (OR = 3.33, 95% CI = 1.73–6.42), and those allergic to penicillin (OR = 3.13, 95% CI = 1.57–6.22) were more likely to experience severe PLCBL (p < 0.05). Implants placed in the anterior area (OR = 2.08, 95% CI = 1.16–3.73), with bone-level platform-abutment connection (OR = 4.73, 95% CI = 1.94–11.49) and inserted supracrestally (OR = 3.77, 95% CI = 1.84–7.72), presented a greater risk of developing severe PLCBL (p < 0.05). Implants placed in a previously grafted area presented a lower likelihood of developing severe PLCBL (OR = 0.489, 95% CI = 0.28–0.84).
Conclusion
The incidence of PLCBL ⩾ 0.5 mm and ⩾1.5 mm was 24.4% and 10.5%, respectively. Male sex, diabetes, allergy to penicillin, anterior location, bone-level platform-abutment connection, and supracrestal implant placement are potential risk factors for severe PLCBL. A previously grafted area is a potential protective factor.

BackgroundThe present cross‐sectional study was undertaken to evaluate the periodontal and microbiological parameters in patients with surgically repaired unilateral cleft lip and palate (UCLP) undergoing orthodontic correction in comparison to patients without any cleft or orthodontic treatment.MethodsA total of 120 patients, out of initial 148 patients, between the age group 6 and 18 years were enrolled and divided into four groups with 30 patients each: non‐cleft patients without orthodontic treatment in Group 1, non‐cleft patients undergoing fixed orthodontic treatment in Group 2, patients with UCLP without any orthodontic treatment in Group 3, and patients with UCLP undergoing fixed orthodontic treatment in Group 4. Periodontal parameters including plaque index (PI), gingival index (GI), gingival bleeding index (GBI), community periodontal index of treatment needs (CPITN) index, pocket probing depth (PD), and tooth mobility were measured in all the groups. The subgingival plaque samples of all the patients were subjected to microbial evaluation using matrix‐assisted laser desorption ionization‐time of flight mass spectrometry (MALDI‐TOF‐MS) for clinical diagnosis.ResultsThe periodontal parameters were significantly raised in Group 4, followed by Group 3 and Group 2 in comparison to Group 1 (p < 0.01), thereby suggesting poor periodontal health in patients with UCLP undergoing orthodontic treatment. Statistically significant differences (p < 0.01) in counts of micro‐organisms among the groups were observed for P. gingivalis, P. intermedia, Veillonella, and Capnocytophaga, with the highest proportions in Group 4, indicating a deteriorating oral health in these patients.ConclusionPoor periodontal and microbial health in patients with UCLP undergoing orthodontic treatment indicates a need for reinforcement of oral hygiene practices among these patients.

BackgroundTo explore the correlation between short‐chain fatty acids (SCFAs) in the peri‐implant sulcular fluid (PISF) and peri‐implant diseases.MethodsPISF samples were obtained from implants that have been placed for at least 5 years, and peri‐implant clinical parameters were examined. Gas chromatography‐mass spectrometry and high‐performance liquid chromatography were used to detect SCFAs in PISF. The correlation between SCFAs and clinical parameters was analyzed by Spearman's correlation. SCFAs related to peri‐implant disease were identified by logistic regression and ranked by random forest analysis.ResultsEighty‐six implants were divided into a peri‐implant health group (PIH‐group, 35 implants), peri‐implant mucositis group (PIM‐group, 25 implants), and peri‐implantitis group (PI‐group, 26 implants) according to clinical and radiographic examination results. The PIM‐group had significantly lower formic acid detection rate than the other two groups (p < 0.001). The PIM‐group had significantly higher levels of acetic, propionic, and isovaleric acids than the PIH‐group (p < 0.05). The PI‐group had significantly higher levels of propionic, butyric, isobutyric, valeric, and isovaleric acids than the PIH‐group (p < 0.05). The PI‐group had significantly higher levels of butyric, isobutyric, and isovaleric acids than the PIM‐group (p < 0.05). SCFAs (apart from hexanoic and succinic acids) were significantly and positively correlated with clinical parameters (p < 0.05). SCFAs related to peri‐implant disease were ranked as follows: butyric, isovaleric, isobutyric, propionic, acetic, formic, and lactic acids.ConclusionsElevated specific SCFAs are correlated with peri‐implant disease. Recognition of this correlation may help in early identification of peri‐implant disease and guide further clinical interventions.

BackgroundBacterial‐induced inflammation instigates the destruction of hard and soft tissues surrounding teeth in periodontitis. In severe cases, the increased number and activity of osteoclasts induces the resorption of alveolar bones, ultimately leading to tooth loss. Because of their diverse chemical structures and bioactivities, natural compounds are often suggested to treat a wide variety of diseases, including inflammatory disorders.MethodsIn the present study, we demonstrated an inhibitory effect of gossypetin, a hexahydroxy flavone, on osteoclast differentiation and bone resorption using in vitro culture of osteoclasts from mouse bone marrow macrophage (BMM) precursors and in vivo model of ligature‐induced periodontitis in mice.ResultsGossypetin significantly reduced the differentiation of osteoclasts from mouse BMM precursors in the presence of the receptor activator of nuclear factor κB ligand (RANKL). In vitro, gossypetin inhibited critical signaling events downstream of RANKL including the auto‐amplification of nuclear factor of activated T‐cells, cytoplasmic 1, Ca2+ oscillations, and the generation of reactive oxygen species. In a mouse ligature‐induced periodontitis model, the administration of gossypetin significantly reduced osteoclastogenesis and alveolar bone resorption. Furthermore, gossypetin prevented the ligature‐induced increase in macrophages and T cells and reduced the production of tumor necrosis factor‐α and interleukin‐6.ConclusionTaken together, these results show anti‐osteoclastogenic and anti‐inflammatory effects of gossypetin, suggesting the potential use of this natural compound in periodontitis.
背景在牙周炎中，细菌引起的炎症会破坏牙齿周围的软硬组织。在严重的情况下，破骨细胞数量和活性的增加会诱发牙槽骨的吸收，最终导致牙齿脱落。方法在本研究中，我们利用小鼠骨髓巨噬细胞（BMM）前体的破骨细胞体外培养和体内结扎诱导的小鼠牙周炎模型，证实了格桑吡丁（一种六羟基黄酮）对破骨细胞分化和骨吸收的抑制作用。结果格桑吡丁能在核因子κB配体受体激活剂（RANKL）存在的情况下明显减少小鼠骨髓巨噬细胞前体破骨细胞的分化。在体外，格塞品抑制了 RANKL 下游的关键信号事件，包括活化 T 细胞核因子的自动扩增、细胞质 1、Ca2+ 振荡和活性氧的产生。在小鼠结扎诱导的牙周炎模型中，格桑吡丁能显著减少破骨细胞的生成和牙槽骨的吸收。此外，格桑吡丁还能防止结扎诱导的巨噬细胞和 T 细胞的增加，并减少肿瘤坏死因子-α 和白细胞介素-6 的产生。结论综上所述，这些结果表明格桑吡丁具有抗破骨细胞生成和抗炎作用，表明这种天然化合物有可能用于治疗牙周炎。

Background: The treatment of leprosy reactions (LRs) involves thalidomide, corticosteroids, and other immunomodulatory medications. This study evaluated the effect of these treatments on the association between periodontitis and LRs, as well as factors associated with LRs.Methods: This case–control study was conducted on 283 individuals followed at a leprosy outpatient clinic in Brazil. The case group was comprised of 158 individuals presenting type 1 or type 2 LRs, and the control group of 125 leprosy individuals without reactions. A complete oral examination was performed to diagnose periodontitis, the independent variable. Antireaction medication used was collected from medical records, and participants were classified according to the use of prednisone and/or thalidomide, time of use, or non‐use of medication. Socioeconomic–demographic, clinical, and lifestyle covariables were collected by interview. Unconditional logistic regression analysis by subgroups evaluated the effect of antireaction medication on the association between periodontitis and LRs, estimating the odds ratio with a 95% confidence interval (OR; 95% CI).Results: A relationship between periodontitis and LRs was observed only in the subgroup using the association prednisone and thalidomide: ORadjusted = 0.32; 95% CI = 0.11–0.95. Conversely, more severe periodontal clinical parameters were observed in cases versus controls. Several socioeconomic, health conditions, and lifestyle factors were associated with the presence of LRs.Conclusions: Although periodontal disease indicators were worse among the cases, the findings showed a negative relationship between periodontitis and LRs in individuals receiving associated prednisone and thalidomide. These medications appear to influence the inflammatory cascade between diseases, modifying and masking the manifestations of periodontitis.
背景：麻风反应（LRs）的治疗包括沙利度胺、皮质类固醇和其他免疫调节药物。本研究评估了这些治疗方法对牙周炎与麻风反应之间关系的影响，以及与麻风反应相关的因素：这项病例对照研究的对象是巴西麻风病门诊的 283 名随访者。病例组包括158名出现1型或2型LRs的麻风病人，对照组包括125名无反应的麻风病人。为诊断牙周炎（自变量）进行了全面的口腔检查。从医疗记录中收集所使用的抗反应药物，并根据泼尼松和/或沙利度胺的使用情况、使用时间或未使用药物对参与者进行分类。社会经济-人口学、临床和生活方式协变量通过访谈收集。按分组进行的无条件逻辑回归分析评估了抗反应药物对牙周炎与LRs之间关系的影响，估计了带有95%置信区间（OR；95% CI）的几率比：结果：仅在使用泼尼松和沙利度胺的亚组中观察到牙周炎与 LRs 之间的关系：调整后 OR = 0.32；95% CI = 0.11-0.95。相反，在病例与对照组中观察到更严重的牙周临床参数。一些社会经济、健康状况和生活方式因素与LRs的存在有关：结论：虽然病例的牙周病指标较差，但研究结果表明，在接受泼尼松和沙利度胺治疗的患者中，牙周炎和LRs之间存在负相关。这些药物似乎会影响疾病之间的炎症级联，改变和掩盖牙周炎的表现。

BackgroundThis study was designed to test the hypothesis that the leptin receptor (LepR) regulates changes in periodontal tissues and that the overexpression of the receptor for resolvin E1 (ERV1) prevents age‐ and diabetes‐associated alveolar bone loss.MethodsLepR‐deficient transgenic (TG) mice were cross‐bred with those overexpressing ERV1 (TG) to generate double‐TG mice. In total, 95 mice were divided into four experimental groups: wild type (WT), TG, LepR deficient (db/db), and double transgenic (db/db TG). The groups were followed from 4 weeks up to 16 weeks of age. The natural progression of periodontal disease without any additional method of periodontitis induction was assessed by macroscopic and histomorphometric analyses. Osteoclastic activity was measured by tartrate‐resistant acid phosphatase (TRAP) staining.ResultsAt 4 weeks, ERV1 overexpression prevented weight gain. From Week 8 onward, there was a significant increase in the weight of db/db mice with or without ERV1 overexpression compared to the WT mice, accompanied by an increase in glucose levels. By 8 weeks of age, the percentage of bone loss in the LepR deficiency groups was significantly greater compared to WT mice. ERV1 overexpression in the db/db TG mice prevented early alveolar bone loss; however, it did not impact the development of diabetic bone loss in aging mice after the onset of weight gain and diabetes.ConclusionsThe findings suggest that the overexpression of ERV1 prevents LepR‐associated alveolar bone loss during the early phases of periodontal disease by delaying weight gain, diabetes onset, and associated inflammation; however, LepR deficiency increases susceptibility to naturally occurring inflammatory alveolar bone loss as the animal ages, associated with excess weight gain, onset of diabetes, and excess inflammation.

ERV1 overexpression in the db/db TG mice prevented early alveolar bone loss; however, it did not impact the development of diabetic bone loss in aging mice after the onset of weight gain and diabetes.ConclusionsThe findings suggest that the overexpression of ERV1 prevents LepR‐associated alveolar bone loss during the early phases of periodontal disease by delaying weight gain, diabetes onset, and associated inflammation; however, LepR deficiency increases susceptibility to naturally occurring inflammatory alveolar bone loss as the animal ages, associated with excess weight gain, onset of diabetes, and excess inflammation.","PeriodicalId":16716,"journal":{"name":"Journal of periodontology","volume":null,"pages":null},"PeriodicalIF":4.3,"publicationDate":"2024-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141448247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Background: Increasing evidence indicates that periodontitis contributes to systemic low-grade inflammation. Porphyromonas gingivalis is strongly associated with periodontitis, and antibodies against the bacterium may be used as a serological proxy to account for periodontal status, when studying diseases associated with periodontitis. The aim of the present study is to identify an easily accessible and reliable serological biomarker for determination of periodontal status and oral carriage of the bacterium.
Methods: Saliva and serum samples were collected from periodontally healthy controls (n = 27), and patients with periodontitis stage II (n = 12) or stages III or IV (n = 44). Serum levels of immunoglobulin G (IgG) antibodies against intact and fragmented P. gingivalis, recombinant gingipains (RgpA and RgpB), and the bacteria Escherichia coli and Capnocytophaga ochracea as controls were quantified with a multiplex bead-based assay. P. gingivalis was identified in saliva using quantitative polymerase chain reaction (qPCR).
Results: Serum IgG antibodies against P. gingivalis whole bacteria were good indicators of periodontitis (area under the curve [AUC]: 0.75, 95% confidence interval [CI]: 0.64-0.85). The same was observed for levels of antibodies against P. gingivalis fragments (AUC: 0.78, 95% CI: 0.68-0.88). Likewise, levels of antibodies against P. gingivalis whole bacteria or P. gingivalis fragments were good indicators of oral carriage of P. gingivalis (AUC: 0.92, 95% CI: 0.86-0.98 and AUC: 0.96, 95% CI: 0.92-1, respectively). Conversely, antibodies against recombinant RgpA and RgpB were not good indicators of periodontitis or oral carriage of the bacterium. None of the antibody levels differed significantly between stage II and stage III or IV periodontitis.
Conclusion: Serum IgG antibody levels against heat-inactivated whole P. gingivalis proved to be the preferable biomarker for periodontitis and oral carriage of the bacterium.
背景：越来越多的证据表明，牙周炎会导致全身性低度炎症。牙龈卟啉单胞菌（Porphyromonas gingivalis）与牙周炎密切相关，在研究与牙周炎相关的疾病时，针对牙龈卟啉单胞菌的抗体可作为一种血清学替代物来说明牙周状况。本研究的目的是确定一种易于获得且可靠的血清学生物标志物，用于确定牙周状况和该细菌的口腔携带情况：方法：从牙周健康的对照组（27 人）和牙周炎 II 期（12 人）、III 期或 IV 期（44 人）患者中采集唾液和血清样本。采用基于多聚酶珠的检测方法对血清中针对完整和片段牙龈脓杆菌、重组牙龈肽（RgpA 和 RgpB）以及作为对照的大肠杆菌和嗜口荚膜梭菌的免疫球蛋白 G (IgG) 抗体水平进行量化。使用定量聚合酶链反应（qPCR）鉴定唾液中的牙龈脓疱疮杆菌：结果：血清中针对牙龈脓疱病菌的 IgG 抗体是牙周炎的良好指标（曲线下面积 [AUC]：0.75，95% 置信区间 [CI]：0.64-0.85）。针对牙龈片段的抗体水平也是如此（AUC：0.78，95% 置信区间：0.68-0.88）。同样，针对牙龈脓杆菌全菌或牙龈脓杆菌片段的抗体水平也是牙龈脓杆菌口腔携带的良好指标（AUC：0.92，95% CI：0.86-0.98；AUC：0.96，95% CI：0.92-1）。相反，针对重组 RgpA 和 RgpB 的抗体不是牙周炎或口腔带菌的良好指标。II期牙周炎与III期或IV期牙周炎的抗体水平均无明显差异：结论：针对热灭活全牙龈脓毒性杆菌的血清 IgG 抗体水平被证明是牙周炎和口腔带菌的理想生物标志物。

Background
The primary purpose of this two-arm, parallel design, randomized controlled study is to compare healing of the palatal tissue donor site when platelet-rich fibrin (PRF) is used as a wound dressing compared to the use of a hemostatic agent. Secondary outcomes of patient pain perception and analgesic intake were also evaluated.
Methods
Seventy-four patients receiving free gingival grafts were randomized to receive either PRF (test) or hemostatic agent (control) as a palatal wound dressing by patients selecting a sealed envelope containing their group assignment (initially 37 envelopes for PRF group and 37 for hemostatic agent group). Patient pain assessment and analgesic consumption were documented using a 21-point numerical scale (NMRS-21) at 24, 48, and 72 hours post-surgery. At 1-, 2-, 3-, and 4-week follow-up appointments palatal early healing index (PEHI) scores including wound color, epithelialization, presence or absence of swelling, granulation tissue, and bleeding on gentle palpation were generated by direct intraoral examination by a blinded examiner unaware of the patients’ treatment group.
Results
NMRS-21 pain scores showed a significant reduction in pain over time in both groups, with no significant difference between groups at any time point. No significant between-group difference was found in the amount of analgesics taken by patients at 24, 48, and 72 hours. There was significant improvement in PEHI scores over the 4-week time period in both groups, but there was no significant difference in PEHI score at each time point (1, 2, 3, 4 weeks) between groups.
Conclusions
Study findings suggest that there is no difference in early palatal wound healing, patient pain perception, or analgesic consumption between use of PRF or a hemostatic agent as donor-site wound dressings.

Background: To date, the clinical evidence regarding the effectiveness of alveolar ridge preservation (ARP) in restricting alveolar bone height and width change after extraction at periodontally compromised molar extraction sockets still remains controversial. This retrospective cohort study aims to evaluate the effect of ARP in molars extracted for periodontal reasons.
Methods: Retrospective data were collected from patient electronic records from January 2019 to December 2023. Patients with Stage III/IV periodontitis who underwent extraction of molars for periodontal reasons were screened for eligibility. The outcomes included the horizontal and vertical dimensions of alveolar bone. The need for additional augmentation procedure during implantation was also evaluated. A linear regression model was used to adjust for known confounders.
Results: A total of 80 sockets were included in this study, of which 27 sockets received ARP therapy after extraction while 53 sockets experienced natural healing (NH). ARP resulted in significantly less bone height change in the periodontally compromised molar sites compared to the NH group (p < 0.001). In sockets displaying a height disparity of >2 mm between the buccal and palatal/lingual walls, the ARP group exhibited advantageous outcomes in terms of ridge width change, surpassing the NH group (p = 0.004). Moreover, the percentage for additional augmentation was significantly reduced in the ARP compared to the NH group (p = 0.006). Age, sex, smoking, jaw, location, and buccal wall thickness did not show any significant effect on bone height change.
Conclusion: ARP had benefits on limiting ridge resorption subsequent to molar extraction for periodontal reasons.

Implant surface decontamination is a critical step in peri-implantitis treatment. The aim of this study was to assess the effect chemotherapeutic agents have on reosseointegration after treatment on ligature-inducted peri-implantitis.
Methods
Six male canines had 36 implants placed and ligatures were placed around them for 28 weeks to establish peri-implantitis. The peri-implant defects were randomly treated by 1 of 3 methods: 0.12% chlorhexidine (CHX test group), 1.5% sodium hypochlorite (NaOCl test group), or saline (Control group). Sites treated with NaOCl and CHX were grafted with autogenous bone, and all sites then either received a collagen membrane or not. Histology sections were obtained at 6 months postsurgery to assess percentage of reosseointegration.
Results
Thirty-five implants were analyzed (CHX: 13; NaOCl: 14; Control:8). NaOCl-treated sites demonstrated reosseointegration with direct bone-to-implant-contact on the previously contaminated surfaces (42% mean reosseointegration), which was significantly higher than Controls (p < 0.05). Correspondingly, clinical improvement was noted with a significant reduction in probing depth from 5.50 ± 1.24 mm at baseline to 4.46 ± 1.70 mm at 6-months postsurgery (p = 0.006). CHX-treated sites demonstrated a nonsignificant reosseointegration of 26% (p > 0.05); however, in the majority of cases, the new bone growth was at a distance from the implant surface without contact. Probing depths did not improve in the CHX group. The use of membrane did not influence reosseointegration or probing depths (all p > 0.05).
Conclusion
Titanium implants with peri-implantitis have the capacity to reosseointegrate following regenerative surgery. However, treatment response is contingent upon the chemotherapeutic agent selection. Additional chemical treatment with 1.5% NaOCl lead to the most favorable results in terms of changes in defect depth and percentage of reosseointegration as compared to CHX, which may hinder reosseointegration.
