Periodontitis as a risk factor for organic erectile dysfunction: A case-control study in a sub-Saharan population.

Background: This study investigated the association between periodontitis and organic erectile dysfunction (ED) in a sub-Saharan population. Methods: This multicenter analytical study lasted from April to September 2021. A total of 114 patients (38 cases and 76 controls) were recruited and matched on age, diabetes, and smoking status. Medical history and ED were recorded, as well as the plaque index, bleeding index, maximum interdental clinical attachment loss (CALmax), maximum probing depth, clinically detectable furcation involv ement, number of teeth in the mouth, number of teeth lost for periodontal reasons, and tooth mobility. The analysis was performed with SPSS 20.0 with a significance threshold set at 5%. Results: The two study groups were comparable regarding sociodemographic characteristics. Periodontitis was present in 76.31% of cases and 75% of controls without a significant difference (P=0.878). Logistic regression showed a significant association between high blood pressure and ED with an OR=4.78 (95% CI: 1.80‒12.70). Periodontitis was not associated with ED (OR=1.52, 95% CI: 0.55‒4.16); however, severe periodontitis was significantly associated with severe ED (OR=1.44, 95% CI: 1.11‒1.85, and OR=1.68, 95% CI: 1.15‒2.44, respectively for CALmax and tooth loss). Conclusion: Within the limits of this study, periodontitis was not associated with organic ED. However, the severity of periodontal disease significantly increased in patients with organic ED.

New classification of periodontal diseases (NCPD): an application in a sub-Saharan country.

PURPOSE: To determine the clinical and radiological profile of periodontitis according to the 2018 NCPD, in a Dakar (Senegal) based periodontal clinic. METHODS: This is a descriptive study based on patient's records in the periodontology clinic. The study was conducted between November 2018 and February 2020 (15 months). All periodontitis cases were included in the study. Incomplete records (due to lack of radiographic workup or unusable periodontal charting) were excluded. Periodontitis diagnosis was established based on criteria used in the 2018 NCPD. Statistical analysis was carried out using SPSS version 20.0, with the significance threshold set at 0.05. RESULTS: A total number of 517 patient records were collected during the study period but only 127 periodontitis records were complete. The mean age of participants was 46.8 ± 13.8 years and 63.8% of participants were males. The mean plaque index and bleeding on probing (BOP) were 74% ± 21.3 and 58.1% ± 25.1, respectively. The mean maximum clinical attachment loss was 8.7 mm ±2.7, with a probing depth greater than 6 mm present in 50.4% of the sample. The median number of missing teeth was 3 (interquartile range 5-1). Pathological mobility was present in 60.6% of the patients and 78.0% had occlusion problems. Bone crest defect at the most affected site was moderate in 52.8% of cases. The ratio of bone loss to age greater than one concerned 66.1% of the sample. Generalised (81.9%), Stage IV (70.1%) and grade C (69.3%) were the most encountered diagnosis. The disease severity was associated with age (r = 0.241; P < 0.001), BOP (r = 0.230; P = 0.013) and the number of teeth with pathological mobility (r = 0.318; P < 0.001). CONCLUSION: Patients with periodontitis in this study had advanced forms of the disease and required multidisciplinary care. Clinical hindsight is necessary to improve this classification.

Long-term effect of non-surgical periodontal treatment on glycaemic control in patients with diabetes with periodontitis: a systematic review and meta-analysis protocol.

INTRODUCTION: Non-surgical periodontal therapy consisting of scaling and root planning has been shown to be effective in the improvement of glycaemic control in patients with diabetes with periodontitis for up to 3 months. However, questions remain about this beneficial effect over a longer period of time. This systematic review and meta-analysis aims to determine the long-term effect (at least 6 months from the therapy) of non-surgical periodontal therapy with or without adjuvant on glycaemic control of patients with diabetes with periodontitis. METHODS AND ANALYSIS: This systematic review will include randomised control trials with a follow-up period of at least 6 months after initial therapy, with measurement of glycated haemoglobin as the primary endpoint. A literature search will be conducted in MEDLINE, CENTRAL, EMBASE, CINAHL, The Cochrane Oral Health Group Trials Register, and the US National Institutes of Health Trials Registry: ClinicalTrials.gov, from inception to 30 June 2020. Selection of studies, data extraction and bias assessment will be conducted independently by two reviewers. A DerSimonian-Laird random-effect meta-analysis will be conducted to pool studies deemed to be homogeneous. A subgroup analysis will be conducted in case of substantial heterogeneity. Egger's test and observation of the funnel plot will be used to assess publication bias. The statistical analysis will be done using R V.4.0.0 software. ETHICS AND DISSEMINATION: Since primary data are not collected, ethical approval is not required. The final report will be published in a peer-reviewed journal. PROSPERO REGISTRATION NUMBER: CRD42020192635.

A 42-Month Follow-Up of Double Root Fracture of a Lateral Mandibular Incisor.

This case report describes the treatment of a double root fracture of a lateral mandibular incisor and its follow- up over 3.5 years. The reason for the consultation was a tooth mobility following a fall that had occurred 2 days earlier. A test of pulp vitality for tooth 42 was positive. Periodontal probing at the level of the gingival sulcus confirmed the intactness of the epithelial attachment. Retro-alveolar radiographic examination revealed a double root fracture of tooth 42. A semi-rigid extra-coronal splinting was performed and a light grinding of the incisal edge of tooth 42 was then carried out in light of the dislocation of the coronal fragment, and the occlusion was checked with a strip of articulating paper. The outcomes at 6 months revealed that pulp vitality was still preserved, consolidation of the apical fracture had occurred, and the coronal root fracture was starting to heal. The 1-year, 2-year and 3-year follow ups revealed preserved pulp vitality, an absence of a fracture line in apical images, and no root resorption. This case report provides evidence for the preservation of vitality in the setting of a double root fracture.

Evaluation of mineral trioxide aggregate (MTA) versus calcium hydroxide cement (Dycal(®) ) in the formation of a dentine bridge: a randomised controlled trial.

AIM: To assess the effectiveness of mineral trioxide aggregate (MTA) used as an indirect pulp-capping material in human molar and premolar teeth. METHODOLOGY: We conducted a clinical evaluation of 60 teeth, which underwent an indirect pulp-capping procedure with either MTA or calcium hydroxide cement (Dycal(®) ). Calcium hydroxide was compared with MTA and the thickness of the newly formed dentine was measured at regular time intervals. The follow-up was at 3 and 6 months, and dentine formation was monitored by radiological measurements on digitised images using Mesurim Pro(®) software. RESULTS: At 3 months, the clinical success rates of MTA and calcium hydroxide were 93% and 73%, respectively (P = 0.02). At 6 months, the success rate was 89.6% with MTA, and remained steady at 73% with calcium hydroxide (P = 0.63). The mean initial residual dentine thickness was 0.23 mm, and increased by 0.121 mm with MTA and by 0.136 mm with calcium hydroxide at 3 months. At 6 months, there was an increase of 0.235 mm with MTA and of 0.221 mm with calcium hydroxide. CONCLUSIONS: A higher success rate was observed in the MTA group relative to the Dycal(®) group after 3 months, which was statistically significant. After 6 months, no statistically significant difference was found in the dentine thickness between the two groups. Additional histological investigations are needed to support these findings.

Profile of chronic and aggressive periodontitis among Senegalese.

PURPOSE: To describe the profile of chronic and aggressive periodontitis among Senegalese (West Africans) attending the Institute of Dentistry of Dakar. METHODS: A retrospective study was conducted with an inclusion period running from 2001 to 2008. The sample included 413 chronic periodontitis and 151 aggressive periodontitis cases, among them 299 males and 265 females selected from 2,274 records. A Student's independent t-test or Pearson chi-squared test was used for data analysis. RESULTS: The proportion of females with aggressive periodontitis was significantly higher than those with chronic periodontitis (64.9% vs. 40.4%, P<0.001). The aggressive periodontitis patients had an average age of 28.1±8.9 years, and had lost less than 3 teeth. Less than a third of them reported using a toothbrush. Attachment loss was as high as 8 mm and severe lesions had spread to an average of 12 teeth with maximum alveolar bone loss up to 80%. The chronic periodontitis patients had an average age of 44.9±14.0 and had lost on average less than 3 teeth. Nearly 75% used a toothbrush. Attachment loss was significantly higher and lesions were more extensive in the aggressive periodontitis. Chronic periodontitis is associated with risk factors such as smoking or diabetes mellitus in 12.8% versus 0.7% in aggressive periodontitis (P<0.001). Differences between the two groups for most clinical and radiographic parameters were statistically significant. CONCLUSIONS: The profile of aggressive periodontist is characterized by more severe lesions than chronic periodontitis, whereas tooth loss experience is similar in both forms.

[Reciprocal relationships between orthodontics and periodontics: relevance of a synergistic action]. / Rapports réciproques entre orthodontie et parodontologie. Intérêt d'une synergie d'action effective.

The aim of this article is to review evidence on the reciprocal relationships between orthodontics and periodontics. Normal intra-arch and inter-arch relationships have long been considered as an anatomic prerequisite for the preservation of dental health and function. Certain malocclusion traits are associated with difficulties in maintaining good oral hygiene and as a consequence to poor periodontal condition. Therefore, proper alignment of the teeth provided by orthodontic treatment may promote good control of soft deposit and calculus and subsequent periodontal inflammation. The tendency of orthodontic appliances, particularly the brackets and bands to promote the accumulation of plaque and thus increasing the risk of developing localized periodontal disease must however be constantly emphasized. Periodontitis involves progressive loss of the alveolar bone around the teeth, pathological tooth migration and gingival recession with pathological tooth migration and gingival recession as a possible outcome. The effectiveness of orthodontics in conjunction with periodontics in the management of these esthetic and functional defects is highlighted in this review.

Intraarch and interarch relationships of the anterior teeth and periodontal conditions.

This study was undertaken to investigate the association between orthodontic anomalies and periodontal conditions. Three parameters of the intraarch relationship on both dental arches (displacement of contact point, crowding, and spacing) and four parameters of interarch relationship (overjet, open bite, crossbite, and overbite) assessed with either Index of Orthodontic Treatment Need or Index of Complexity, Outcome and Need were correlated with parameters of periodontal condition, ie, hygiene (Plaque Index and Retention Index), inflammation (gingival inflammation and Gingival Bleeding Index), and periodontal disease severity (pocket depth, clinical attachment loss, and gingival recession). In the main, weak but significant correlations were found between certain parameters of intraarch and interarch relationship and some indices of periodontal conditions. Within the limitations of this study, it was concluded that providing orthodontic treatment on the ground of deleterious effect of malocclusion and malpositioned teeth on periodontal condition is justified.
