Ibero-Panamerican Federation of Periodontology Delphi study on the trends of periodontology and periodontics by the year 2030. A Latin American consensus.

BACKGROUND AND OBJECTIVE: As elsewhere in the world, the prevalence of periodontitis in stages I-II is high in the Latin American population, this scenario emphasizes the need for identification of urgent needs for allocating adequate resources to provide diagnosis, prevention, and treatment of these diseases. The aim of this Delphi study was to predict the trends in periodontology/periodontics in the Latin American region by the year 2030. METHODS: A steering committee and an advisory group of experts in periodontology/periodontics were selected from 16 countries. An open questionnaire of 60 questions was validated and used following the Delphi methodology. RESULTS: Two hundred and twenty-five experts from Latin America answered the two rounds of the questionnaire. Moderate to strong consensus was reached on 45 questions (75%). The prediction was that the prevalence of gingivitis and periodontitis in stages I and II will be maintained, the importance of the link with systemic diseases will increase, and the impact of prevention and periodontal treatment will also increase, mainly in the private sector. There was a strong consensus that plastic and regenerative surgical procedures will increase, as well as the demand for training in the specialty of periodontology. CONCLUSIONS: The present study has provided relevant and useful information on predictions in periodontology/periodontics in Latin America, with important level of consensus among experts. It has been predicted that periodontitis will still be a highly prevalent disease, and its links with other medical conditions should demand more attention by health authorities to develop adequate prevention and management policies and strategies.

Overview of systematic reviews on periodontal-orthodontic interactions: A comprehensive literature analysis.

The aims of this research were to investigate the methodological quality of systematic reviews on periodontal-orthodontic interactions (i.e. reviews of primary research broadly defined as any including both periodontic and orthodontic components) and to provide a mapping of the researched topics. We searched four major databases (PubMed, Lilacs, Web of Science, and Embase) for systematic reviews of periodontal-orthodontic interactions. We used the AMSTAR-2 tool (the acronym is derived from 'a measurement tool to assess systematic reviews') to assess the methodological quality of the included systematic reviews. Individual AMSTAR-2 ratings were tabulated, and the percentage per item was calculated. To assess the association between the AMSTAR-2 percentage score and the overall confidence in the systematic review results, an ordinal regression model was used. We initially retrieved 973 documents, and 43 systematic reviews were included. Systematic reviews of interventions were the most prevalent (n = 26, 60.5%). Most of the systematic reviews did not report a meta-analysis (n = 25, 58.1%). In addition, most of the studies included in the systematic reviews had an unclear or high risk of bias. Most of the systematic reviews were rated as having critically low or low overall confidence (n = 34, 79.1%). A significant correlation was found between the AMSTAR-2 percentage score and overall confidence in the results. The methodological quality of systematic reviews on periodontal-orthodontic interactions can be improved. The limitations of our study include potential language bias and an arbitrary classification of the topics researched.

A critical look at outcome measures: Comparison between four dental research journals by use of a hierarchical model.

AIM: To assess the status quo of outcome measures used in treatment studies in Endodontics, and potentially identify strategies for improvement, by (i) systematically assessing the outcome measures using a conceptual model and (ii) comparing these with measures used in corresponding studies in the adjacent fields. METHODOLOGY: The International Endodontic Journal, Caries Research, The Journal of Clinical Periodontology and The Journal of Oral & Facial Pain and Headache were selected to cover four adjacent dental disciplines. In each journal, the 50 most recent consecutive publications fulfilling inclusion criteria were included. A hierarchical model for diagnostic imaging studies was modified to assess studies related to treatment. The model comprised six levels, with technical as the lowest level and societal as the highest. Extracted data included study origin, study type, and identified outcome measures. Fisher's Exact Tests with Bonferroni corrections compared studies. p < .05 was considered statistically significant. RESULTS: Amongst 756 publications, the 200 most recent studies matching the inclusion criteria were identified. Less than half (36.5%) assessed the clinical, patient, or societal aspects of treatment; 10.0% in International Endodontic Journal, 28.0% in Caries Research, 38.0% in Journal of Clinical Periodontology, and 70.0% in Journal of Oral & Facial Pain and Headache (p < .001). CONCLUSIONS: According to included publications, research on treatment within the endodontic field is mainly focusing on technical and biological outcomes. The benefits of patients and society were less frequently examined than in corresponding journals in adjacent disciplines. When designing studies, including higher-level outcomes should be considered.

Qualitative somatosensory evaluation of recipient and donor sites of subepithelial connective tissue grafts: a preliminary study.

OBJECTIVES: The subepithelial connective tissue graft (SCTG) plus coronal advanced flap is commonly evaluated by clinical parameters, but potential sensory changes (patients' perception of painful or painless sensations) need to be further explored. This preliminary study aimed to qualitatively evaluate the somatosensory profile of recipient and palatal donor sites of SCTG. MATERIALS AND METHODS: Sensory tests were applied at SCTG recipient and donor sites at baseline, after 3 and 6 months. A single calibrated examiner applied Douleur Neuropathique 4 questionnaire (DN4), qualitative sensory test (QualST), discriminating the areas as hypersensitive, hyposensitive or normosensitive, and two-point acuity test. Descriptive statistics, non-parametric Kruskal Wallis test for QualST evaluation and ANOVA for Two-point test (p < 0.05) were used. RESULTS: QualST revealed that recipient areas presented no significant differences in tactile, pressure and thermal tests. Brush test revealed hyposensitivity after 3 months (p = 0.03). In donor areas, only thermal evaluation showed a significant difference (p = 0.01), being hypersensitive after 3 months and hyposensitive after 6 months. At baseline, all evaluations in recipient and donor areas were normosensitive. According to DN4, no patient reported pain in recipient and donor sites. Non-painful sensory perception was reported as numbness in recipient (3.14% of patients) and donor (18.4%) areas. No significant differences were found for two-point acuity test values. CONCLUSIONS: Somatosensory variations were observed in donor and recipient areas using qualitative tests, with no detection of painful sensations, only non-painful sensations of numbness and electric shock. CLINICAL RELEVANCE: This preliminary study demonstrated that alterations of hypo- and hypersensitivity may occur in donor and recipient areas of gingival grafts. However, when present, these alterations were non-painful and did not impact oral functions. CLINICAL REGISTRATION: ReBEC #RBR-7zz3b6p.

Platelet-Rich Plasma (PRP) and Injectable Platelet-Rich Fibrin (i-PRF) in the Non-Surgical Treatment of Periodontitis-A Systematic Review.

The gold standard in the non-surgical treatment of periodontitis is scaling and root planing (SRP). In recent years, the use of autogenous platelet concentrates has spread over many specialties in dentistry and, thus, has also been gaining popularity in periodontal treatment. Its two main fractions are platelet-rich plasma (PRP) and platelet-rich fibrin (PRF), which, since 2014, can also be used via injection as injectable platelet-rich fibrin (i-PRF). The authors conducted a comprehensive systematic review in accordance with the PRISMA 2020 guidelines. It involved searching PubMed, Embase, Scopus, and Google Scholar databases using the phrases ("Root Planing" OR "Subgingival Curettage" OR "Periodontal Debridement") AND ("Platelet-Rich Plasma"). Based on the authors' inclusion and exclusion criteria, 12 results were included in the review, out of 1170 total results. The objective of this review was to ascertain the impact of utilizing PRP and i-PRF in SRP. The results revealed that both the incorporation of PRP and i-PRF were found to be significantly associated with are duction in gingival pocket depth and again in clinical attachment level; however, i-PRF demonstrated superiority in improving clinical parameters. Furthermore, i-PRF demonstrated notable bactericidal efficacy against Porphyromonas gingivalis. On the other hand, PRP proved inferior to an Nd:YAG laser in clinical parameter improvement; however, it demonstrated significant efficiency as well. This literature review led the authors to the conclusion that autologous platelet concentrates might be competent agents for improving the therapeutic outcomes of SRP.

Importance of periodontal phenotype in periodontics and restorative dentistry: a systematic review.

BACKGROUND: Periodontal phenotype is regarded to be one of the key factors influencing the efficacy of restorative therapies in dental practice. The objective of the systematic review was to explore the importance of thin and thick periodontal phenotypes and how they affect the outcome of periodontal and restorative therapies by looking at a number of academic publications from various online databases. METHODS: Following the PRISMA guidelines (Preferred Reporting Items for Systematic Review standards), relevant data will be searched and retrieved from three significant scientific databases, including PubMed, EBSCO, and Scopus. The articles with full texts that matched the keywords and published in English between 2018 and 2023 were taken into consideration. RESULTS: The majorities of these articles were based on the type of periodontal phenotype and their impact on periodontal and restorative treatment outcomes were selected. The initial search yielded a total of 530 articles. Only 273 were relevant to the review's objectives, and these were considered for determining eligibility. Only 20 publications were eligible for analysis. CONCLUSION: Understanding these anatomical aspects of periodontal phenotype is crucial to both periodontology and restorative dentistry. The clinical outcome of restorative, prosthetic, orthodontic, surgical, and periodontal therapies is determined in large part by the periodontal phenotype, which also plays a significant role in clinical failure or success in dental treatments. TRIAL REGISTRATION: This study protocol registered with the International Prospective Register of Systematic Reviews (PROSPERO) dated 16th June 2023 with the registration ID CRD42023432568.

Treatment of deep gingival recession in homologous molars using a modified laterally positioned flap and subepithelial connective tissue graft: a case report.

This case report describes the use of the modified laterally positioned flap (LPF) technique associated with a subepithelial connective tissue graft (SCTG) for root coverage of homologous mandibular molars with deep gingival recession (GR). A 25-year-old woman with deep GR affecting the mandibular right and left second molars (teeth 31 and 18, respectively) reported bilateral dentinal hypersensitivity. The defect in tooth 31 was 5 mm deep and 4 mm wide. In tooth 18, the defect was 6 mm deep and 5 mm wide. There was 1 mm of keratinized tissue at tooth 31, and no keratinized tissue was present at tooth 18. The modified LPF-SCTG technique with mesial to distal positioning of the flap was selected to treat the defects. The flap was modified by a submarginal incision in the tooth farthest from the GR to preserve the integrity of the donor site. One year postsurgery, tooth 31 had 80.0% coverage, a 66.6% gain in clinical attachment, and a 5-mm increase in keratinized tissue width. Tooth 18 had 83.3% root coverage, a 71.4% gain in clinical attachment, and a 5-mm increase in keratinized tissue width. The patient's complaints of hypersensitivity were resolved, and the tissue gain provided better access and more comfort during cleaning of the teeth. The flap donor sites demonstrated no clinical signs of GR. Based on the 1-year follow-up assessments, the modified LPF-SCTG technique was effective for the treatment of deep single-tooth GR in mandibular molars without causing adverse affects on the flap donor sites.

New Trends in the Impact of Periodontal Treatment on Early Cardiovascular Diseases Outcomes: Insights and Future Perspectives.

Cardiovascular diseases represent the primary worldwide cause of mortality, and periodontitis is the main cause of tooth loss. The incidence of atherosclerotic disease has been reported to be higher in individuals affected by periodontitis than in individuals without, regardless of many common risk factors are present. Various pathogenetic models have been presented to clarify the close correlation between these two diseases. First, periodontal bacteria and their toxins can enter the circulation both during dental procedures and normal activities such as eating and teeth brushing. Periodontal bacteria may indirectly contribute to coronary artery disease (e.g., by causing immunological reactions) or directly by damaging coronary arteries. Periodontal treatment significantly reduces periodontal pathogens such as Porphyromonas gingivalis (Pg) or Actinobacillus actinomycetemcomitans (Aa) in deep periodontal pockets. Moreover, periodontal treatment may lower blood inflammatory mediators, enhance the lipid profile, and cause favourable changes in various surrogate markers for cardiovascular disease. The way in which oral bacteremia and periodontal inflammation cause atherosclerosis is still unclear and needs further studies. The real effectiveness of periodontal treatment in preventing cardiovascular events is a topic of current interest. In this regard, this review article explores new insights and provides an indication of future directions on the function of periodontal inflammation and oral bacteria in the incidence and progression of atherosclerosis and cardiovascular diseases, with the main focus on assessing the impact of periodontal treatment on cardiovascular disease outcome biomarkers.

Reporting of flow diagrams in randomised controlled trials published in periodontology and implantology: a survey.

BACKGROUND: Item 13 of the CONSORT guidelines recommends documentation of the participant flow in randomised clinical trials (RCTs) using a diagram. In the medical literature, the reporting of the flow of participants in RCTs has been assessed to be inadequate. The quality of reporting flow diagrams in periodontology and implantology remains unknown. The aim of this study was to assess the reporting of flow diagrams in RCTs published in periodontology and implantology journals. MATERIALS AND METHODS: RCTs published between 15th January 2018 and 15th January 2022 in twelve high-ranked periodontology and implantology journals were identified. Trial characteristics at the RCT level were extracted. The flow diagram included in each RCT was assessed for completeness of reporting in relation to published criteria and the CONSORT flow diagram template. RESULTS: From the 544 eligible articles, 85% were single-centre, 82% of parallel-group design and 79% investigated surgical interventions. Three-hundred and fifteen (58%) articles were published in CONSORT endorsing journals. A flow diagram was reported in 317 (58%) trials and reporting was more common in periodontology (73.1%). Overall, 56% of publications with a flow diagram reported a complete CONSORT flow diagram, while in 44% of flow diagrams, at least one point from the CONSORT reporting template was missing. Reasons for loss to follow-up (69.7%) and exclusions from the RCT analysis (86.4%) were poorly reported. CONCLUSION: The reporting of flow diagrams in periodontology and implantology RCTs was sub-optimal. Greater awareness of the importance of fully completing the participant CONSORT flow diagram is required.

Influence of decision-making algorithms on the diagnostic accuracy using the current classification of periodontal diseases-a randomized controlled trial.

OBJECTIVES: To examine the influence of the decision-making algorithms published by Tonetti and Sanz in 2019 on the diagnostic accuracy in two differently experienced groups of dental students using the current classification of periodontal diseases. MATERIALS AND METHODS: Eighty-three students of two different clinical experience levels were randomly allocated to control and study group, receiving the staging and grading matrix, resulting in four subgroups. All diagnosed two patient cases with corresponding periodontal charts, panoramic radiographs, and intraoral photographs. Both presented severe periodontal disease (stage III, grade C) but considerably differed in complexity and phenotype according to the current classification of periodontal diseases. Controls received the staging and grading matrix published within the classification, while study groups were additionally provided with decision-trees published by Tonetti and Sanz. Obtained data was analyzed using chi-square test, Spearman's rank correlation, and logistic regression. RESULTS: Using the algorithms significantly enhanced the diagnostic accuracy in staging (p = 0.001*, OR = 4.425) and grading (p < 0.001**, OR = 30.303) regardless of the clinical experience. In addition, even compared to the more experienced control, less experienced students using algorithms showed significantly higher accuracy in grading (p = 0.020*). No influence on the criteria extent could be observed comparing study groups to controls. CONCLUSION: The decision-making algorithms may enhance diagnostic accuracy in dental students using the current classification of periodontal diseases. CLINICAL RELEVANCE: The investigated decision-making algorithms significantly increased the diagnostic accuracy of differently experienced under graduated dental students and might be beneficial in periodontal education.

Assessment of suturing and scaling skills of periodontology and oral medicine residents by OSATS method: a pilot study.

INTRODUCTION: Updating the method for evaluating suturing and scaling skills in dental education has attracted relatively little attention and there is no consensus to what should be assessed and how. The purpose of this study was to investigate the applicability of the Objective Structured Assessment of Technical Skill (OSATS) method for these two basic skills, the possible association between the scores and demographic factors, and the level of satisfaction of residents with this method. METHODS: All six periodontics and three oral medicine residents were recruited by census method and video-recorded while performing a simple interrupted suture, a figure eight suture and scaling on a model. Then, the videos were evaluated independently via a checklist and a global rating scale (GRS) by two expert raters. Agreement between raters and residents' satisfaction were evaluated. Correlation between demographic factors of participants and scores was also assessed. T-test and linear regression analysis were used. RESULTS: There was no significant difference between the scores based on the views of the two raters for each of the checklist (ICC = 0.99, CI = 0.96-0.99, P < 0.001) and GRS (ICC = 0.97, CI = 0.86-0.99, P < 0.001). Linear regression showed no correlation between gender and scores but periodontics major and higher year of education showed correlation with higher scores. CONCLUSION: Considering the excellent agreement between raters in using both the checklist and GRS components of OSATS, and satisfaction of 88% the residents with this method, it seems to be able to provide a reliable assessment.

Influence of the timing of periodontal intervention on periapical/periodontal repair in endodontic-periodontal lesions: a systematic review.

INTRODUCTION: This study is aimed at answering the following question: "Does the timing of periodontal intervention influence the periapical/periodontal repair in endodontic-periodontal lesions?". MATERIAL AND METHODS: Six electronic databases were systematically searched for studies published up to April 2022, without restriction of language or year of publication, following the PIOS strategy: (P) adult patients with a diagnosis of endodontic-periodontal lesions, (I) endodontic and periodontal treatment, (O) periapical and periodontal healing, and (S) clinical studies. Risk of bias assessment was performed with the revised Cochrane risk of bias tools for randomized trials (RoB 2) and non-randomized interventions (ROBINS-I). The overall quality of evidence was assessed through the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) tool. RESULTS: Three studies (one prospective, one retrospective, and one randomized clinical trial) were included in the present review. Non-randomized studies had a critical and serious risk of bias. The randomized clinical trial had some concerns risk of bias. Non-randomized studies reported that the endodontic intervention should be performed previous to the periodontal intervention. Randomized clinical trial reported improvements when endodontic and periodontal interventions were performed simultaneously. GRADE analysis showed a very low quality of evidence for both randomized and nonrandomized studies. CONCLUSIONS: Based on the evidence from the included studies, although it is suggested that the endodontic treatment should be performed prior to periodontal treatment, it is not possible to assure the best treatment sequence for endodontic-periodontal lesions. CLINICAL RELEVANCE: Evidences suggests that although the endodontic intervention should be the first therapy of choice, it was not possible to specify the best time to perform the periodontal intervention.

Impact of periodontitis on circulating cell-free DNA levels as a measure of cardiovascular disease.

OBJECTIVES: The present study aims to assess the serum circulating cell-free (cfDNA) concentrations in patients with periodontitis and cardiovascular disease (CVD) and to evaluate the impact of periodontitis on circulating cfDNA levels and the confounding factors that might mediated the possible relationship. MATERIALS AND METHODS: Healthy controls (n=30) and patients with CVD (n=31), periodontitis (n=31), and periodontitis + CVD (n=30) were enrolled in the present study. All subjects underwent regular periodontal examination and blood sampling and cfDNA evaluation. The analysis of the plasma cfDNA concentrations was performed using a dsDNA Assay Kit. RESULTS: In comparison with healthy controls and CVD patients, periodontitis and periodontitis+CVD exhibited significantly higher expression of circulating cfDNA (p<0.05). There was a positive correlation among plasma cfDNA and clinical attachment loss (CAL) (p=0.019), high sensitivity C-reactive protein (hs-CRP) (p=0.027), and periodontal inflamed surface area (PISA) (p=0.003). Furthermore, the multivariate regression analysis evidenced that PISA (p<0.001), hs-CRP (p=0.014), and full-mouth bleeding score (FMBS) (p=0.004) were significant predictors of circulating cfDNA concentrations. CONCLUSIONS: The results of the study highlighted that the periodontitis and periodontitis + CVD group showed higher circulating cfDNA expression in comparison with healthy controls and CVD patients. Moreover, the extent of periodontitis was correlated with the increased cfDNA levels and represented a significant predictor of the increased circulating cfDNA concentrations. CLINICAL RELEVANCE: Unbalanced circulating cfDNA concentrations have been indicated to represent a possible risk of CVD and endothelial dysfunction. Periodontitis and periodontitis + CVD patients showed higher circulating cfDNA expression; moreover, the extent of periodontitis significantly predicted higher circulating cfDNA concentrations, suggesting the potential increased risk of developing CVD in periodontitis patients.

A comparative analysis of dual-axis implants placed into maxillary anterior extraction sockets versus virtual planning with uniaxial implants: A simulated cone beam computed tomography study of implant length and diameter.

OBJECTIVE: The biaxial nature of the anterior maxilla poses a surgical and restorative challenge in implant dentistry. The present study sought to investigate the apical socket perforation rate (ASPR) from a simulated uniaxial implant placement and to determine the effect of implant length and diameter on ASPR when a uniaxial implant was placed compared with the orientation of the pre-existing dual-axis implant. MATERIAL AND METHOD: Cone beam computed tomography (CBCT) scans from the database of three private practices were searched for patients who received dual-axis implants within the esthetic zone in immediate tooth replacement therapy. A uniaxial implant was virtually placed using the pre-existing screw access channel of the dual-axis implant as a reference. The closest length and diameter were selected for the simulated implant. ASPR by the uniaxial implant was recorded. In addition, the affordable maximum length of a corresponding uniaxial implant that would avoid apical socket perforation was measured. RESULT: Eighty-one patients with a total of 101 dual-axis dental implants were selected for analysis. A simulated virtual surgical planning with uniaxial implants revealed high ASPR (48.51%). When the length of the uniaxial implant was reduced to 11 and 9 mm, ASPR was decreased to 41.58% and 20.79%, respectively. CONCLUSION: Dual-axis implant design effectively evades anatomical challenges in the anterior maxilla (esthetic zone). Considering the current evidence, efforts should be made to carefully consider the angular disparity between the extraction socket-alveolus complex and the future restorative emergence so that a harmonious biologic-esthetic result may be more predictably and consistently obtained.

Impact of Circulating Cell-Free DNA (cfDNA) as a Biomarker of the Development and Evolution of Periodontitis.

In the last few decades, circulating cell-free DNA (cfDNA) has been shown to have an important role in cell apoptosis or necrosis, including in the development and evolution of several tumors and inflammatory diseases in humans. In this regard, periodontitis, a chronic inflammatory disease that can induce the destruction of supporting components of the teeth, could represent a chronic inflammatory stimulus linked to a various range of systemic inflammatory diseases. Recently, a possible correlation between periodontal disease and cfDNA has been shown, representing new important diagnostic-therapeutic perspectives. During the development of periodontitis, cfDNA is released in biological fluids such as blood, saliva, urine and other body fluids and represents an important index of inflammation. Due to the possibility of withdrawing some of these liquids in a non-invasive way, cfDNA could be used as a possible biomarker for periodontal disease. In addition, discovering a proportional relationship between cfDNA levels and the severity of periodontitis, expressed through the disease extent, could open the prospect of using cfDNA as a possible therapeutic target. The aim of this article is to report what researchers have discovered in recent years about circulating cfDNA in the development, evolution and therapy of periodontitis. The analyzed literature review shows that cfDNA has considerable potential as a diagnostic, therapeutic biomarker and therapeutic target in periodontal disease; however, further studies are needed for cfDNA to be used in clinical practice.

The crown lengthening double guide and the digital Perio analysis.

OBJECTIVE: This article describes a surgical crown lengthening double guide, which was digitally obtained to improve diagnosis, treatment outcome, and follow-up. CLINICAL CONSIDERATIONS: The rehabilitation of anterior dental esthetics should involve interdisciplinary and facially driven planning for achieving pleasant long-term outcomes. Surgical crown lengthening is one of the most common periodontal surgery, which can be assisted by digital tools to improve surgical planning and follow-up. CONCLUSION: The double guide for surgical crown lengthening allows the proper management of hard and soft tissues for achieving a predefined goal based on biological requirements and facially driven planning. In addition, the digital quality control allows the follow-up compared with the pre-operative condition and planned treatment plan. CLINICAL SIGNIFICANCE: The use of digital tools allow the clinician to develop a facially driven planning with proper communication with the team and patient, leading to a shorter, more predictable, and less invasive surgical technique, reducing postoperative inflammation and increasing patient comfort.

Oral health profile and periodontal diseases awareness and knowledge among the jordanian population: a cross-sectional study.

OBJECTIVE: To explore the oral health profile and periodontal diseases awareness and knowledge among the Jordanian population. In addition, we aimed to identify predictors of good knowledge of periodontal diseases. METHOD: This was an online cross-sectional survey study that was conducted in Jordan between January and May 2022. A total of 13 item from the world health organisation (WHO) oral health questionnaire for adults were used to examine the oral health profile of our study participants. In addition, a previously developed questionnaire by Abdulbaqi et al. were adapted and used to examine participants' knowledge about periodontal diseases. Binary logistic regression analysis was used to identify predictors of better knowledge of periodontal diseases. RESULTS: This study involved 1,099 participants in total. More than half of them (61.1%) claimed that throughout the previous 12 months, they had experienced pain or discomfort in their mouths or teeth. Nearly half of the participants said their teeth and gums were in good or very good condition. 70.7% said they brush their teeth once or more per day. The vast majority of them (93.0%) claimed to brush their teeth using toothpaste that contained 61.9% fluoride. The most frequent cited cause for dental visits was pain or difficulty with teeth, gums, or mouth (36.3%), according to almost one-third of study participants who said they had visited a dentist during the previous six months. The most commonly reported problems that occurs frequently due to the state of the participants' teeth or mouth were avoiding smiling because of teeth, feeling embarrassed due to appearance of teeth, and having difficulty in biting foods with 11.0%, 10.2%, and 9.0%, respectively. Tea with sugar (16.5%) was the most frequently reported beverage as being consumed frequently on a daily basis. The most popular tobacco product to be smoked often on a daily basis was cigarettes (21.6%). For periodontitis knowledge questions, the percentage of accurate responses ranged from 32.3 to 55.8%. The majority of participants (55.8%) were able to recognize that poor oral hygiene is one of the most frequent causes of malodor, whereas the least number of participants (32.3%) were able to recognize that improper teeth brushing is a frequent cause of gingival recession. CONCLUSION: The average degree of periodontitis knowledge among Jordanians was moderate. Along with it, there were modest oral hygiene practices. In order to prevent further oral complications that have a detrimental influence on patients' quality of life, educational campaigns are required to increase public awareness of knowledge and practices in terms of proper oral hygiene and periodontitis.

Factors affecting the maxillary and mandibular incisors' buccolingual inclinations and buccal and lingual cortical plate heights.

INTRODUCTION: Orthodontics is closely related to periodontics. The buccolingual inclination (BLI) of the incisors and deficiencies in their buccal (BHd) and lingual (LHd) cortical plate heights may affect orthodontic outcomes. Identifying risk factors that can compromise buccal or lingual bone heights may have clinical value. The literature on BLI/BHd/LHd is not only scarce but also limited to one jaw. We aimed to examine, for the first time, factors affecting BLI/BHd/LHd not evaluated before as well as other factors with scarce literature about them. METHODS: In this two-phase epidemiological and analytical study, inclinations and cortical heights of 248 incisors (bilateral centrals and laterals) were evaluated blindly on 62 randomly selected high-resolution pretreatment cone-beam computed tomography volumes (30 maxillae [13 men, 17 women], 32 mandibles [13 men, 19 women]). The sample was balanced in terms of sexes, jaws, and ages. The BLI/BHd/LHd of bilateral incisors were measured (intraobserver agreement > 95%). The effects of jaws, sexes, age, sides, and incisor types on each of the anatomical variables (BLI/BHd/LHd) were analyzed using a Mixed-Model Multiple Linear Regression analysis. Correlations among continuous variables were assessed using a Pearson coefficient (α = 0.05). RESULTS: For the maxillary centrals, BLI, BHd, and LHd were 106.79 ± 5.06, 1.94 ± 0.95, and 1.50 ± 0.76, respectively. These parameters were '110.56 ± 5.97, 1.81 ± 0.83, 1.23 ± 0.69' for the maxillary laterals; '97.64 ± 8.26, 2.98 ± 1.48, 3.46 ± 1.45' for the mandibular centrals; and '95.98 ± 6.80, 3.29 ± 1.72, and 2.73 ± 1.15' for the mandibular laterals. BLI was greater in the maxilla compared to the mandible and in the lateral incisors compared to centrals (P < 0.05). BHd was greater (more deficient) in the mandible (P = 0.000). Age, sex, or side were not associated with BLI (P > 0.05). Age, sex, side, or incisor types were not associated with BHd (P > 0.05). LHd was greater in the mandible, older individuals, and centrals (P < 0.05). There were some significant but weak correlations between BLI with BHd and especially LHd (P < 0.05). CONCLUSION: In the maxilla, but not in the mandible, incisors' BLI may determine LHd. Maxillary incisors may have greater BLIs as well as greater buccal and lingual alveolar bone heights compared to mandibular incisors. BLI might be greater in the laterals compared to the centrals in both jaws combined.

Effectiveness of distance learning for preclinical periodontal education.

INTRODUCTION: This study aimed to investigate the effectiveness of distance learning (DL) for the second-year periodontics course compared to classroom learning (CL). MATERIALS AND METHODS: DL for Class A (n1 = 126) and CL for Class B (n2 = 133) were implemented. The same instructors recorded or delivered the same lectures in the two learning modules during the second-year periodontics course. Classes A and B took the same final examinations (a total % score of 200). General linear model (GLM) and ordinal logistic regression (OLR) analyses were conducted after considering individual first-year final % scores as a covariate to test if the second-year final % scores and the distributions of letter grades were significantly different between Class A and B. RESULTS: The mean second-year final % score of the DL group (166.4) was significantly higher than that of the CL group (160.8) (independent t-test, p = .019). However, in GLM, the first-year final % scores significantly affected the second-year scores (p = .016); the second-year final % scores between the two groups were not significantly different (p = .268) after considering the individual first-year scores. In OLR, there was no difference in the likelihood of getting lower grades in the second-year course between the two groups (odds ratio = 1.6; 95% confidence interval = [0.95, 2.72], p = .078) after considering the first-year final % scores. CONCLUSION: Within the limitations of the study, the DL for preclinical periodontics resulted in comparable student learning outcomes when compared to the traditional CL.

ASSESSMENT OF THE FREQUENCY OF REPORTING DENTAL PATIENT-REPORTED OUTCOMES (dPROs) IN A SAMPLE OF RANDOMIZED CONTROLLED TRIALS ON ROOT COVERAGE PROCEDURES.

OBJECTIVE: Dental patient-reported outcomes (dPROs) are important for understanding the impact of proposed therapies on patients' oral health. The aims of the present study were to investigate the frequency of the reporting of dPROs in randomized controlled trials (RCTs) of root coverage procedures and to assess associations between the study/article characteristics and the reporting level of the dPROs. METHODS: The PubMed database was searched for RCTs of root coverage procedures in March 16, 2022 and articles published up to March 2022 were included. Information on the types of outcomes and the characteristics of the studies/articles were extracted and reported as frequencies and percentages. Univariate and multivariate binary logistic regression analyses were performed to investigate the associations between the study/article characteristics and the reporting level of dPROs. RESULTS: The search initially identified 387 articles, and after applying the eligibility criteria, 135 articles reporting 135 RCTs were included. A combination of dPROs and non-dPROs was reported in 61.5% of the selected trials, while 37.8% of the trials reported only non-dPROs. Pain or discomfort was the most frequently reported dPRO (n = 58, 43% of the RCTs). More recently published RCTs reported more dPROs. The country of the first author (odds ratio [OR]: 4.39; 95% CI: 1.76-10.95; P < .01), protocol registration (OR: 0.36; 95% CI: 0.16-0.83; P = .02), and RCT type (OR: 0.38; 95% CI: 0.17-0.83; P = .02) were significantly associated with the reporting level of the dPROs. CONCLUSIONS: Researchers in recent years seem to be paying more attention to the importance of dPROs. RCTs in which the first authors were from developed countries, registered trials, and RCTs with a parallel design were more likely to report dPROs than RCTs with first authors from developing countries, unregistered trials, and RCTs with a split-mouth design.
