RESUMEN
Periodontal disease affects 42% of adults in the United States. Both the periodontal microbiome and the host immune inflammatory response may be influenced by overweight/obesity status. This retrospective analysis sought to determine the associations of periodontal disease parameters with body mass index (BMI) and obesity status in patients undergoing periodontal maintenance therapy. The records of 418 patients who were undergoing periodontal maintenance after periodontitis treatment were examined, and the patients' demographic characteristics (sex, age, and race/ethnicity), self-reported BMI, periodontal disease condition, number of sites with probing depth ≥ 4 mm, missing teeth, and sites with bleeding on probing (BOP) were recorded. Patients were determined to have active moderate to severe periodontitis if they presented with 2 or more sites in 2 different quadrants with clinical attachment loss ≥ 5 mm and probing depth ≥ 5 mm. Individuals were also categorized into 3 groups: underweight/normoweight, BMI < 25; overweight, BMI 25 ≤ 30; or obese, BMI ≥ 30. In the study population, BMI ranged from 16.827 to 51.389. The periodontitis status was not significantly associated with a BMI status of overweight (odds ratio [OR] = 1.388 [95% CI, 0.961- 2.006]) or obese (OR = 1.168 [95% CI, 0.77-1.757]). Female sex (OR = 0.561 [95% CI, 0.343-0.918]) and age (OR = 0.983 [95% CI, 0.967-0.999]) were negatively associated with active periodontitis status. Obese patients demonstrated significantly more sites with BOP than either underweight/normoweight or overweight patients, and a BMI indicating obesity was associated with increasing age (P < 0.001) and higher number of missing teeth (P = 0.0064). In a population of patients undergoing periodontal maintenance therapy, BMI was associated with age and missing teeth, and obese status was associated with a significantly higher number of sites with BOP.

OBJECTIVES: This retrospective study aimed to evaluate the influence of anatomical, patient and surgical factors on the occurrence of membrane perforation (MP) during lateral window sinus floor elevation (LWSFE). MATERIAL AND METHODS: A review of LWSFE patient records between 2014 and 2019 accounted for MP occurrence, window surface area (WSA), intravenous sedation use, osteotomy instrument type and clinician experience. Preoperative cone beam computed tomography (CBCT) scans were analyzed for lateral wall thickness (LWT), LFM and LAM angles formed between lateral and medial walls at the floor and anterior wall, respectively, sinus width at 5-, 10- and 15-mm (LM-5, LM-10 and LM-15) from the floor, residual bone height (RBH), sinus pathologies, septa and arterial anastomoses. The generalized estimating equation (GEE) approach with a sandwich variance-covariance estimator was used to evaluate the associations with MP. RESULTS: MP occurred in 25.74% of 202 LWSFE procedures (166 patients). Mean 1.6 mm-LWT, 3.2 mm-RBH, 95°-LFM, 75.5°-LAM, 12 mm-LM-5, 20.79% septa, 16.83% arterial anastomosis, 37.62% sinus pathology and 29.21% intravenous sedations, 85.24% WSA ≥ 40 mm2 and 57% >10 procedures/clinician were reported. Greater MP rates were encountered as follows: 38.3% (LWT ≥ 1.5 mm), 38% (LFM < 90°), 59.6% (LAM < 70°), 45.4% (LM-5 < 10 mm) and 36.4% (WSA ranged > 80 mm2 ), with statistically significant associations with all these outcomes (p < .05). The presence of pathologies was also associated with MP (p = .013). Associations between MP and the presence of septa and arterial anastomoses, age/gender, right/left sinus, RBH, clinician's experience, instrument type and intravenous sedation use could not be demonstrated. CONCLUSIONS: MP is significantly associated with thicker lateral walls, narrower sinuses, larger windows and existing sinus pathology.

BACKGROUND: A variety of systemic diseases and conditions can affect the course of periodontitis or have a negative impact on the periodontal attachment apparatus. Gingival recessions are highly prevalent and often associated with hypersensitivity, the development of caries and non-carious cervical lesions on the exposed root surface and impaired esthetics. Occlusal forces can result in injury of teeth and periodontal attachment apparatus. Several developmental or acquired conditions associated with teeth or prostheses may predispose to diseases of the periodontium. The aim of this working group was to review and update the 1999 classification with regard to these diseases and conditions, and to develop case definitions and diagnostic considerations. METHODS: Discussions were informed by four reviews on 1) periodontal manifestions of systemic diseases and conditions; 2) mucogingival conditions around natural teeth; 3) traumatic occlusal forces and occlusal trauma; and 4) dental prostheses and tooth related factors. This consensus report is based on the results of these reviews and on expert opinion of the participants. RESULTS: Key findings included the following: 1) there are mainly rare systemic conditions (such as Papillon-Lefevre Syndrome, leucocyte adhesion deficiency, and others) with a major effect on the course of periodontitis and more common conditions (such as diabetes mellitus) with variable effects, as well as conditions affecting the periodontal apparatus independently of dental plaque biofilm-induced inflammation (such as neoplastic diseases); 2) diabetes-associated periodontitis should not be regarded as a distinct diagnosis, but diabetes should be recognized as an important modifying factor and included in a clinical diagnosis of periodontitis as a descriptor; 3) likewise, tobacco smoking - now considered a dependence to nicotine and a chronic relapsing medical disorder with major adverse effects on the periodontal supporting tissues - is an important modifier to be included in a clinical diagnosis of periodontitis as a descriptor; 4) the importance of the gingival phenotype, encompassing gingival thickness and width in the context of mucogingival conditions, is recognized and a novel classification for gingival recessions is introduced; 5) there is no evidence that traumatic occlusal forces lead to periodontal attachment loss, non-carious cervical lesions, or gingival recessions; 6) traumatic occlusal forces lead to adaptive mobility in teeth with normal support, whereas they lead to progressive mobility in teeth with reduced support, usually requiring splinting; 7) the term biologic width is replaced by supracrestal tissue attachment consisting of junctional epithelium and supracrestal connective tissue; 8) infringement of restorative margins within the supracrestal connective tissue attachment is associated with inflammation and/or loss of periodontal supporting tissue. However, it is not evident whether the negative effects on the periodontium are caused by dental plaque biofilm, trauma, toxicity of dental materials or a combination of these factors; 9) tooth anatomical factors are related to dental plaque biofilm-induced gingival inflammation and loss of periodontal supporting tissues. CONCLUSION: An updated classification of the periodontal manifestations and conditions affecting the course of periodontitis and the periodontal attachment apparatus, as well as of developmental and acquired conditions, is introduced. Case definitions and diagnostic considerations are also presented.

Outcomes for treatment, overall oral health status, and periodontal disease progression in patients with type 2 diabetes mellitus (T2DM) have been associated with glycemic control as measured by hemoglobin A1c (HbA1c) levels. Due to the high prevalence of T2DM among patient populations in the United States, this study sought to assess baseline levels of glycemic control for patients with a known diagnosis of T2DM who were under the care of a physician and to identify management solutions for these patients. All patients included in this study were prescreened to ensure that they were dentate, had been diagnosed with T2DM at least 3 months previously, were under the care of a physician for diabetes management, and had no changes to their diabetes-related medications for 3 months or more (N = 822). The patients meeting those criteria were then screened in person, and those who had moderate to severe chronic periodontitis, had at least 20 teeth, and met other inclusion/exclusion criteria were qualified to participate in the study (N = 214). After the patients fasted, a whole blood sample was drawn and subjected to HbA1c testing. The mean (SD) HbA1c for the qualified patients was 7.76% (1.79%), and the values ranged from 5.1% to 18.8%. Among the 214 qualified individuals, 150 (70.1%) had HbA1c values greater than 6.5%. Of these 150 patients, 80 (53.3%, or 37.4% of the total screened sample) presented with HbA1c values greater than 8.0%. The majority of patients with periodontitis and physician-managed T2DM did not meet ideal standards for glycemic control. Dental healthcare providers should consider consultation and/or advanced screening for diabetic patients seeking dental care.

BACKGROUND: Pregnant women demonstrate increases in gingivitis despite similar plaque levels to non-pregnant counterparts. AIM: To evaluate an intensive protocol aimed at reducing gingivitis in pregnant women and provide pilot data for large-scale randomized controlled trials investigating oral hygiene measures to reduce pregnancy gingivitis and alter maternity outcomes. MATERIALS AND METHODS: One hundred and twenty participants between 16 and 24 weeks gestation with Gingival Index (GI) scores ≥2 at ≥50% of tooth sites were enrolled. Plaque index (PI), gingival inflammation (GI), probing depth (PD), and clinical attachment levels (CAL) were recorded at baseline and 8 weeks. Dental prophylaxis was performed at baseline and oral hygiene instructions at baseline, 4 and 8 weeks. Pregnancy outcomes were recorded at parturition. Mixed-model analysis of variance was used to compare clinical measurements at baseline and 8 weeks. RESULTS: Statistically significant reductions in PI, GI, PD, and CAL occurred over the study period. Mean whole mouth PI and GI scores decreased approximately 50% and the percentage of sites with PI and GI ≥2 decreased from 40% to 17% and 53% to 21.8%, respectively. Mean decreases in whole mouth PD and CAL of 0.45 and 0.24 mm, respectively, were seen. CONCLUSIONS: Intensive oral hygiene regimen decreased gingivitis in pregnant patients.

BACKGROUND: Gingivitis is a non-specific inflammatory lesion in response to the accumulation of oral biofilm and is a necessary precursor to periodontitis. Enhanced oral hygiene practices, including utilization of a dentifrice that could significantly improve plaque accumulation and gingival inflammation, is desirable to prevent and treat gingivitis and potentially prevent progression to periodontitis. This clinical study aimed to investigate the effect of a new stannous fluoride-containing dentifrice with 2.6% ethylenediamine tetra acetic acid (EDTA) as an anti-tartar agent to reduce plaque index and gingival index over a 3-month study period compared to other commercially-available fluoride-containing dentifrices. METHODS: This double-blind, randomized controlled clinical study evaluated plaque, gingival inflammation, and sulcular bleeding in patients using one of five commercially available fluoride-containing dentifrices The dentifrices tested contained: 0.454% stannous fluoride and 2.6% EDTA (D1), 0.24% sodium fluoride (C), and 0.454% stannous fluoride (D2-D4). One hundred fifty subjects participated over a 3-month period. Co-primary endpoints were improvements in plaque index (PI) and modified gingival index (mGI) from baseline values. No professional cleaning was performed during the study period. RESULTS: All subjects in the study demonstrated statistically significant improvements in all measures of oral hygiene over the 3-month study period. Subjects using dentifrice 1 (D1) showed statistically significantly greater reductions in PI, mGI, and modified sulcular bleeding index (mSBI) compared with all other commercially-available dentifrices tested (p < 0.00001). CONCLUSIONS: A new dentifrice with 0.454% stannous fluoride and 2.6% EDTA demonstrated significant improvements in clinical parameters associated with gingivitis compared to other sodium and stannous fluoride containing dentifrices.

BACKGROUND: During pregnancy, dental plaque-induced gingivitis prevalence and subsequent risk of periodontal disease increases substantially, as a consequence of both inadequate oral hygiene and changes in sex steroid hormone levels. Although maternal periodontal disease has been associated with adverse pregnancy outcomes, including spontaneous preterm birth, previous clinical trials involving mechanical debridement (eg, scaling and root planing) to remove plaque biofilm have not yielded decreased rates of preterm birth. OBJECTIVE: We hypothesized that an advanced oral hygiene program, including an antibacterial regimen coupled with a power toothbrush and hygiene instruction, may improve the periodontal milieu and reduce the rate of spontaneous preterm birth. Therefore, we conducted a clinical trial of obstetrical patients with moderate-to-severe gingivitis who were randomized to an advanced oral hygiene program vs usual oral hygiene care, and the primary obstetrical outcome compared between the treatment groups was gestational age at delivery. STUDY DESIGN: Obstetrical patients with singleton pregnancies between 8 and 24 weeks' gestation were screened by trained dentists at 2 clinical sites for moderate-to-severe gingivitis (>30 intraoral sites with gingival bleeding on probing). Eligible participants were randomized to an advanced oral hygiene regimen, including antibacterial mouth wash, dental floss, antibacterial toothpaste, a power toothbrush, and intensive oral hygiene education vs standard oral home care instructions and regimen. The primary obstetrical outcome assessed was gestational age at delivery. The overall primary (dental) outcomes were gingival index, bleeding sites, and pocket depth (reported elsewhere). Secondary obstetrical outcomes included birthweight and incidence of preterm birth at <37 weeks' gestation. Regression models were utilized and included factors such as treatment group, gestational age at enrollment, preterm birth history, and potential markers of health disparities (ie, education, employment status). RESULTS: A total of 817 obstetrical patients underwent dental screening at the 2 sites, 789 were identified with moderate-to-severe gingivitis, 746 were randomized, and birth outcomes were available for 613 of the study participants. The gestational age at delivery was 2 days earlier in the control group (P=.040), but the clinical significance of this finding was limited (39.13 vs 38.85 weeks). Overall rates of spontaneous preterm birth <37 weeks and <34 weeks were not statistically different between the 2 treatment groups (7.0% advanced oral hygiene regimen vs 10.3% controls, OR=1.63 (0.90-3.00), P=.11; and 2.3% vs 3.9%, OR=1.88 (0.71-4.98), P=.20, respectively). However, we observed lower rates of spontaneous preterm birth among unemployed participants with less favorable socioeconomic status (4.7% advanced oral hygiene regimen vs 16.0% controls, OR=4.04 (1.34-15.12), P=.01). CONCLUSION: An advanced oral hygiene program may reduce the risk of spontaneous preterm birth among pregnant patients with moderate-to-severe gingivitis and health disparities. This is the same group that may be at highest risk of poor dental hygiene and preterm birth.

INTRODUCTION: Research shows there is a significant increase in gingival inflammation during pregnancy. This study was conducted to determine if an oral health intervention (OHI), including oral hygiene education delivered by nurse-led staff and an advanced over-the-counter (OTC) oral home care regimen, improved gingival inflammation in pregnant women with moderate-to-severe gingivitis compared with a standard oral hygiene control group. METHODS: This was a multicenter, randomized, controlled, single-masked, parallel group clinical trial conducted in obstetrics clinics of 2 medical centers. A total of 750 pregnant women between 8 and 24 weeks of pregnancy with at least 20 natural teeth and moderate-to-severe gingivitis (>30 intraoral bleeding sites) were enrolled. Participants were randomized to either the OHI group, which included oral hygiene instructions supplemented with an educational video and advanced OTC antibacterial/mechanical oral hygiene products, or the control group receiving oral hygiene instructions and standard products. Both groups received oral hygiene instructions from nurse-led staff. Experienced, masked examiners measured whole mouth gingival index (GI) and periodontal probing depths (PDs) at baseline and months 1, 2, and 3. RESULTS: Participants enrolled in this study presented with moderate-to-severe gingivitis at baseline. Both the OHI and control groups exhibited significant reductions in GI (P < .001) and PD (P < .03) from baseline that persisted throughout the study period. The OHI group exhibited modest, yet statistically greater, reductions in GI (P ≤ .044) compared with the control at all time points. The reduction in PD directionally favored the OHI group, but between-group differences were small (<0.03 mm) and not statistically significant (P > .18). DISCUSSION: Significant gingivitis was prevalent among participants in this study and identifies an opportunity to improve gingival health during pregnancy by providing oral health education during the course of prenatal care when coupled with an advanced OTC oral hygiene regimen.

Assessment of patient- and prosthetic-specific factors in identifying the ideal implant-supported prosthesis helps enable the delivery of a dental restoration that can meet the esthetic, functional, physiologic, psychologic, financial, and time goals of the patient. For practitioners, determining the relative risks and benefits of removable and fixed implant-supported prostheses for restoration of an edentulous maxilla can be challenging. Proper treatment selection requires thorough examination, diagnosis, and a systematic approach to treatment planning. Consideration of both prosthetic and surgical outcomes is necessary to ensure the restoration of facial structures and oral function. This article discusses three prosthetic parameters essential to determining whether a patient's needs can be best met with a fixed or removable prosthesis: prosthetic space, lip support, and transition line. Standardized treatment planning considerations are presented to facilitate the clinician's step-by-step diagnostic and decision-making processes.

BACKGROUND: Mucogingival deformities are prevalent oral conditions and can result in esthetic compromise, dentinal hypersensitivity, and an increase in radicular caries rates. Mucogingival treatments address thin periodontal phenotype and/or gingival recession defects. Although many of these grafting procedures are predictable in improving soft-tissue quality and quantity around teeth and dental implants, patients often complain of discomfort at both the donor and recipient sites. Free gingival grafts and coronally advanced flaps alone or in combination with subepithelial connective tissue graft and/or acellular dermal matrix are among the most common surgical procedures employed to achieve root coverage and enhance periodontal phenotype. Autologous blood products (ABPs) contain platelets, growth factors, leukocytes, and stem cells that contribute to cell mitosis, collagen production, and angiogenesis, leading to the healing and regeneration of hard and soft tissue. Evaluation of the adjunctive role of ABPs in mucogingival surgery and their impacts on clinical and patient-centered data is critical to achieve optimal patient-reported outcome measures based upon the current scientific evidence. METHODS: We present exemplar cases in which adjunctive ABPs were utilized in mucogingival treatment to enhance treatment outcomes. RESULTS: No adverse events were noted. Satisfactory treatment outcomes were achieved in patients with local and/or systemic compromise when mucogingival therapies were used in combination with ABPs. CONCLUSIONS: Adjunctive use of ABPs may enhance outcomes of mucogingival therapy. Utilization of adjunctive ABPs may be particularly advantageous in situations where the predictability of clinical and esthetic outcomes is limited due to anatomical and/or patient factors.

Retention is a critical phase of orthodontic therapy and aims to maintain occlusal stability and avoid crowding relapse. This best-evidence article reviews the effects of the different types of orthodontic retention appliances, fixed and removable, on the development and progression of gingival recession at the mandibular anterior teeth. Searched databases included PubMed, Scopus, Cochrane Library, Embase, and Dentistry and Oral Sciences. Eleven qualifying publications, including retrospective, prospective, and cross-sectional studies, were included in this review. These studies either did not demonstrate an association between orthodontic retainers and gingival recession or reported that the resulting recession defects were minimal when an association was shown. An important consideration is that recession could be a late finding following the placement of a retainer and, therefore, may be incipient or absent in short-term evaluations. Prospective studies that specifically address the role that properly positioned fixed retainers may have on gingival recession are needed before a definitive conclusion can be generalized with regard to recommended retention protocols. Factors such as duration of retainer use, number of bonded teeth, and position of fixed retainers relative to their proximity to gingival tissues are not fully elucidated but may have influencing roles on gingival recession. The use of retainers should be based on orthodontic indications to maintain a stable dental arch form, esthetics, and occlusion. Effective oral hygiene and follow-up regimens remain the gold standard in maintaining periodontal health and preventing gingival recession.

The aim of this randomized prospective study was to compare clinical and patient-centered outcomes of Miller Class I and II gingival recession defects treated with acellular dermal matrix (ADM) grafts and either vestibular incision subperiosteal tunneling access (VISTA) or sulcular tunnel access (STA) techniques. A total of 29 gingival recession defects in nine patients were assessed to determine clinical outcomes, including probing depth (PD), gingival recession (GR), width of keratinized tissue (KT), width of attached tissue (AT), tissue thickness at the gingival margin (TT1), and tissue thickness 4 mm apical to the gingival margin (TT2). Visual analog scale (VAS) assessment of patient-perceived pain, bleeding, swelling, and changes in activity were assessed postoperatively at 7 and 30 days, and professional assessment of postoperative esthetics using the Pink Esthetic Score (PES) was performed at 6 months. All sites demonstrated significant improvements in midfacial GR. No statistically significant differences were noted between the VISTA and STA groups for clinical or patient-centered outcomes, except for preferable midfacial AT in the VISTA sites at 6 months. These findings indicate that both surgical techniques can be used with ADM grafts to achieve improvements in root coverage, alterations in periodontal phenotype, and improved esthetics with high levels of patient satisfaction.

The role of the microbiota in the pathogenesis of arthritis is gaining increasing attention. While multiple studies have queried the intestinal microbiota, very few have analyzed the contents of the oral microbiota. In this pilot study, we obtained salivary and sub-gingival specimens from a cohort of six healthy controls and five children with well-controlled spondyloarthritis (SpA) and performed 16S sequencing on bacteria obtained from both habitats. The Quantitative Insight into Microbial Ecology tool suite was used to generate operational taxonomic units, Phyloseq was used for diversity analyses, and DeSeq2 was used to compare abundances while adjusting for multiple comparisons. A repeat specimen was obtained from one subject during a flare. Clustering based upon diagnosis was observed from both habitats, with decreased alpha diversity seen within the plaque obtained from the patients vs. controls. Among the differentially abundant taxa were statistically significantly increased plaque Fusobacterium and salivary Rothia mucilaginosa among the patients compared to the controls. Additionally, the abundance of plaque Fusobacterium increased in one patient at the time of a flare. Our data suggest that the oral cavity may harbor bacteria involved in the pathogenesis of spondyloarthritis; additional studies are warranted.
RESUMEN
FOCUSED CLINICAL QUESTION: What are the key considerations of the incidence and timing for single-tooth implant complications, including early failure, biological complications, and prosthetic complications? SUMMARY: Single-tooth dental implants have been shown to have a high overall survival rate, but implant complications affect patient satisfaction and may lead to costly and/or time-consuming repair and revision. Assessing the incidence and types of biologic and prosthetic complications and the timing of such complications is helpful so that the underlying causes can be addressed during the treatment planning process. Furthermore, identification of patient demographics, patient-, implant-, and site-specific factors associated with such complications may allow for more comprehensive risk assessment during treatment planning. CONCLUSIONS: Overall, dental implants have a high survival rate. Identification of the incidence of both biologic and prosthetic complications and minimizing their impact in patients with dental implants is critical to overall implant success. Utilization of careful treatment planning and dental implant fixtures, surgical protocols, and prosthetic designs that reduce complication rates can improve patient acceptance and outcomes. Further research is necessary to fully assess complication rates and risk factors.

PURPOSE/OBJECTIVES: Using the periodontal diseases classification published in 2018, this study evaluated the level of agreement among predoctoral and postgraduate students of different education levels and specialties in the diagnosis and treatment planning of periodontal conditions. METHODS: Second-year (D2) and fourth-year (D4) dental students, postgraduate orthodontic students (OS), and periodontology students (PS) were presented with an anonymous survey of 10 cases, each with five choices of diagnosis and seven therapeutic approaches. The cases included a patient summary, photographs, radiographs, periodontal charting, and ranged from health to periodontitis. Consensus diagnosis, used as a gold standard, was established between two experienced periodontists. Diagnosis and treatment choices for each case were compared across educational groups using Fisher's exact test. The level of agreement among educational groups was assessed using a multirater kappa coefficient. RESULTS: The survey was completed in 2020 with a 72.4% overall response rate (57-D2, 45-D4, 17-OS, and 12-PS). The overall level of agreement on diagnosis was fair (κ = 0.24, p <.0001) with PS showing the most agreement (κ = 0.55, p <.0001). There were tendencies to prioritize stage over grade and extent in assigning diagnoses and to overdiagnose disease severity and underdiagnose localized periodontitis. Nonsurgical periodontal therapies had the highest overall agreement (κ = 0.63 for scaling/root planing and κ = 0.44 for maintenance, p <.0001). Response distribution per case and per level of education indicated that PS more consistently agreed with the gold standard than any other group. CONCLUSIONS: OS, D2, and D4 students demonstrated inferior agreement levels compared to PS, successfully recognized health from disease, suggested appropriate treatment plans, and tended to overdiagnose milder periodontal conditions.

FOCUSED CLINICAL QUESTION: When planning dental implant therapy, what risk-reduction strategies allow practitioners to select patients, sites, and restorative plans that decrease the incidence of peri-implant disease? SUMMARY: With a marked increase in the number of patients receiving dental implants to treat partial or complete edentulism, it follows that the prevalence of peri-implant mucositis and peri-implantitis have increased. Risks associated with implant therapies may vary based upon underlying local, environmental, surgical, patient, prosthetic, and fixture-related factors. Furthermore, an emphasis on preventative measures and maintenance should be undertaken to avoid development and progression of peri-implant diseases. Thorough risk assessment, proper treatment planning, and early diagnosis and intervention are critical in the absence of definitive data of long-term success of treatments for peri-implant condition. Given the difficulty in intervention once peri-implantitis is established, identification of risk factors and development of treatment plans to address those factors before dental implant therapy is critical to the long-term health and success of dental implants. CONCLUSIONS: A patient-centered, evidence based approach to dental implant treatment planning to reduce the risk for peri-implantitis should be undertaken. Systematic diagnosis of disease state(s) and evaluation of the etiologic and modifying risk factors for peri-implant diseases can yield more optimal outcomes to reduce peri-implantitis rates.

BACKGROUND: Compliance to periodontal maintenance therapy (PMT) is essential for long-term periodontal health. Between PMT visits, patients must maintain good oral hygiene. A dentifrice with demonstrable clinical benefits for use between PMT visits would be highly desirable. The aim of this clinical study was to investigate the effect of a novel dental gel on probing depths (PD) and inflammation when used as a home care dentifrice in Stage I and II periodontitis patients. METHODS: This double-blind clinical study randomized 65 subjects with Stage I and II periodontitis to the novel dental gel containing 2.6% EDTA, and a commercially available anti-gingivitis dentifrice with 0.454% stannous fluoride. Primary endpoint was PD at 6 months for those sites with baseline PD ≥ 4 mm and secondary endpoints included whole mouth mean scores of modified gingival index (MGI), modified sulcus bleeding index (mSBI) and plaque index (PI). No SRP was performed at baseline. RESULTS: Subjects using the novel dentifrice showed significant PD reductions of 1.18 mm (from 4.27 mm at baseline to 3.09 mm at 6 months) compared to 0.93 mm (from 4.23 mm at baseline to 3.30 mm at 6 months) shown for those using the positive control dentifrice. Difference between treatments at 6 months was 0.21 mm with P-value = 0.0126. Significant improvements in MGI (P = 0.0000), mSBI (P = 0.0000), and PI (P = 0.0102) were also observed in 6 months. CONCLUSION: The novel dentifrice showed significant reductions in PD and gingival inflammation over 6 months solely as a home care dentifrice without baseline SRP in Stage I and II periodontitis maintenance patients.

OBJECTIVE: To test the effects of maternal periodontal disease treatment on the incidence of preterm birth (delivery before 37 weeks of gestation). METHODS: The Maternal Oral Therapy to Reduce Obstetric Risk Study was a randomized, treatment-masked, controlled clinical trial of pregnant women with periodontal disease who were receiving standard obstetric care. Participants were assigned to either a periodontal treatment arm, consisting of scaling and root planing early in the second trimester, or a delayed treatment arm that provided periodontal care after delivery. Pregnancy and maternal periodontal status were followed to delivery and neonatal outcomes until discharge. The primary outcome (gestational age less than 37 weeks) and the secondary outcome (gestational age less than 35 weeks) were analyzed using a chi test of equality of two proportions. RESULTS: The study randomized 1,806 patients at three performance sites and completed 1,760 evaluable patients. At baseline, there were no differences comparing the treatment and control arms for any of the periodontal or obstetric measures. The rate of preterm delivery for the treatment group was 13.1% and 11.5% for the control group (P=.316). There were no significant differences when comparing women in the treatment group with those in the control group with regard to the adverse event rate or the major obstetric and neonatal outcomes. CONCLUSION: Periodontal therapy did not reduce the incidence of preterm delivery. LEVEL OF EVIDENCE: I.

FOCUSED CLINICAL QUESTION: What are the key considerations for effective delivery of oral hygiene home care to best manage or prevent periodontal diseases? BACKGROUND: Plaque control is critical for the management of periodontal diseases, but not all patients demonstrate the same risk for disease progression and challenges differ based upon clinical findings. This report seeks to present evidence-based oral hygiene recommendations for a variety of common periodontal diseases. SUMMARY: Accurate diagnosis, risk assessment, and individualized delivery of oral hygiene instruction is necessary to ensure that patients can provide adequate home care to promote health and maintain the benefits of periodontal therapy. CONCLUSIONS: Oral hygiene techniques and recommendations should vary based upon patients' clinical presentation and risk assessment. Utilization of evidence-based strategies to deliver personalized care will allow for optimal wellness for patients.

BACKGROUND: Guided bone regeneration (GBR) is a widely used procedure for augmenting alveolar ridge width prior to placement of endosseous implants. Various graft materials and barrier membranes (non-resorbable and bioabsorbable) have been used in GBR. The aim of this study was to assess the performance of a new bioabsorbable, synthetic polyglycolic acid/trimethylene carbonate (PGA/TMC) barrier membrane with an increased absorption time in conjunction with a combination of assayed demineralized bone matrix and cortical cancellous chips uniformly dispersed in a thermoplastic biologic carrier. METHODS: At 72 potential implant sites in 38 subjects, ridge width at the crest and 4 mm apical to the crest was measured before and 6 months after a GBR procedure using the long-term (LT) PGA/TMC membrane and an allograft in a thermoplastic carrier. Before placement of endosseous implants, 48 biopsy specimens were obtained from the augmentation sites and analyzed histomorphometrically. RESULTS: The GBR procedure increased the mean ridge width at the crest from 2.4 to 5.2 mm. This 216% change from baseline was significant (P <0.001). The mean width 4 mm apical to the crest increased from 4.4 to 7.5 mm, a significant (P <0.001) 174% change. The histomorphometric analysis showed that the biopsy specimens consisted, on average, of 57% bone (36% graft material and 21% new bone) and 43% soft tissue and space. CONCLUSION: Our findings suggest that the LT PGA/TMC barrier membrane, used in conjunction with an allograft, provides lateral alveolar ridge augmentation comparable to that achieved with other materials without the necessity for bone-graft harvesting or a second procedure to remove the barrier membrane.
