Objectives: To explore associations between periodontal disease (PD) severity and cardiometabolic risk factors, including body mass index (BMI), age, Type 2 Diabetes Mellitus (T2DM) risk, sex, and hypertension (HTN) in patients at an urban dental school clinic.

Methods and materials: A cross-sectional study design was used to analyze electronic health record data, including periodontal status, demographic characteristics, cardiometabolic risk factors and the American Diabetes Association Diabetes Risk Test (DRT) Score. Chi-square tests and ordinal logistic regression were conducted using SAS 9.4.

Results: Of those with available data (n=6,778), 44% were male, 70.2% were overweight/obese, and the mean age was 50.9 (SD=16.6) years. Associations between PD severity and BMI, sex, age, DRT score, and HTN were statistically significant (all p<0.0001) in bivariate analyses. Using logistic regression, HTN (p=0.0006), sex (p<0.0001), and age (p<0.0001) were significant predictors of severe PD which was most common in those with HTN (35.9%), males (31.7%), those >60 years (36.6%). The odds of having severe PD for those with HTN were 1.2 times that of those without HTN. Males were 1.7 times more likely to have severe PD than females. Those aged 40-49 years, 50-59 years, and >60 years were 2.9, 4.2, and 4.3 times more likely to have severe PD than those who were 18-39 years, respectively.

Conclusion: All cardiometabolic risk factors were associated with PD severity in bivariate analyses. In the logistic regression model, being older, male, and having HTN were significant predictors of PD severity. Future research is needed with a more diverse sample.

Objectives: This randomized clinical trial compared the effectiveness of music and informative videos as distraction tools to reduce the anxiety of patients during root canal treatment and retreatment.

Method and materials: A total of 90 patients were enrolled in the study. The patients were randomly allocated to three groups: Group 1 listened to music during the treatment (n = 30), Group 2 watched an informative preoperative video (n = 30), and a control group underwent treatment without a distraction method (n = 30). Prior to treatment, the Corah Dental Anxiety Scale (CDAS) and a visual analog scale for pain were used to assess anxiety and preoperative pain. Systolic blood pressure, diastolic blood pressure, heart rate, and oxygen saturation were recorded before the intervention (T1), after the local anesthetic (T2), following pulp extirpation or removal of root fillings (T3), and immediately following rubber dam removal (T4). One-way ANOVA, followed by post-hoc Bonferroni tests for multiple comparisons, were used to compare mean values of systolic blood pressure, diastolic blood pressure, heart rate, and oxygen saturation among the groups. A P value of 5% was considered as significant.

Results: Listening to music reduced systolic blood pressure, heart rate (P .001), and diastolic blood pressure (P = .003) in patients undergoing root canal treatment and retreatment at T4 compared to the baseline (T1). Music (P .001) and informative video (P = .003) groups had significantly lower postoperative visual analog scale pain scores.

Conclusion: Listening to music during root canal treatment and retreatment reduced anxiety levels in patients compared to informative preoperative videos and no distraction technique.

Objective: Periodontal disease is caused by subgingival bacteria that adversely affect the host immune system and create and maintain unmitigated inflammation in gingival and periodontal tissues. The condition is also linked to systemic conditions including cardiovascular disease, diabetes, and arthritis. Periodontitis elevates the bacterial load and spreads systemic inflammation through infection and inflammation. The main radiographic sign of periodontitis is marginal bone loss. Risk factors, including medications, smoking, age, and sex, are known to influence periodontal health. However, there is little information about the impact of systemic conditions and medications on tooth wear. The aim of the present study was to assess the association between systemic conditions and medications and radiographic signs of tooth wear and marginal bone loss.

Method and materials: This retrospective analysis was conducted on a group of 2,223 consecutive patients who came for dental treatment in the clinics of a large Health Maintenance Organization in Israel. Data available for the study included details of concomitant systemic diseases and medication and full-mouth radiographic surveys. Odds ratio and logistic regression analysis were used to detect associations between systemic conditions and medication, and marginal bone loss and tooth wear.

Results: The results indicated an elevated odds ratio for tooth wear associated with age, sex, and smoking across all age groups. Among young patients, those using proton pump inhibitors and psychiatric medications had an elevated risk of tooth wear. Age, smoking, and diabetes conditions were associated with an increased odds ratio for marginal bone loss in all age groups. Psychiatric medications and sex elevated the odds ratio for marginal bone loss only among older patients.

Conclusion: The results highlight the significant impact of age, sex, and smoking on tooth wear, and extend these risks to alveolar bone loss when combined with diabetes and psychiatric conditions.

Objectives: This study aimed to evaluate the influence of different whitening toothpastes on color change and alteration in enamel surface roughness and microhardness compared to a conventional toothpaste.

Method and materials: Fifty bovine incisors were selected, cleaned, and stored before being divided into five groups: a conventional toothpaste group and three whitening toothpaste groups containing different abrasive agents: silica, hydrogen peroxide, and activated charcoal. Specimens underwent simulated brushing, staining with black tea solution, and subsequent analyses of color, surface roughness, and microhardness. Statistical analysis was performed using three-way ANOVA and Tukey post-hoc tests (P .05).

Results: The results showed that the color analysis revealed similar whitening potential among all toothpastes. They showed significant differences in surface roughness (P .001) and microhardness (P .001) after simulated brushing. While all toothpastes caused a decrease in microhardness, the charcoal-based toothpaste showed a significant increase in surface roughness compared to the initial condition.

Conclusion: All toothpastes demonstrated whitening capability. Surface roughness changed after brushing with activated charcoal-based whitening toothpaste, but final roughness was similar across all groups. Whitening toothpastes led to a decrease in enamel microhardness, with similar final performance across all toothpastes analyzed.

Objective: An altered sensation during endodontic treatment can occur due to the extrusion of endodontic materials. This study aims to discuss intentional replantation to address paresthesia resulting from an endodontic file penetrating the inferior alveolar nerve canal and provide a protocol for managing nerve injuries in such incidents.

Case presentation: A 12-year-old girl developed paresthesia when an endodontic file separated and was inadvertently pushed through the apical foramen into the inferior alveolar nerve canal during root canal treatment of the mandibular left first molar. A CBCT scan revealed the file penetrating the canal towards the inferior border of the mandible. After considering the treatment options, intentional replantation was deemed suitable. The tooth was atraumatically extracted and preserved in sterile saline. The surgeon then carefully cleaned and irrigated the socket. The radiographic assessment confirmed successful file removal from the socket. The root ends were resected, and retrograde preparation and obturation were conducted using ultrasonic tips and mineral trioxide aggregate. The tooth was then replanted into the socket. Successful replantation was confirmed by tooth stability and an audible click. The patient was prescribed antibiotics and steroids. After completion of the endodontic treatment, a stainless steel crown was cemented. The successful intentional replantation procedure resulted in rapid improvement in the patient's condition. The normal sensation had been restored, indicating nerve recovery. At the 15-month follow-up, periapical bone healing and the eruption of the adjacent second molar were observed, affirming the treatment protocol's overall success.

Conclusion: Prompt intervention and immediate intentional replantation facilitated direct inspection of the separated file within the socket. Collaboration between an oral maxillofacial surgeon and an endodontist ensures expedited and targeted treatment, leading to favorable outcomes.

Objective: This review aimed to examine differences in outcomes with the use of intra-articular hyaluronic acid vs corticosteroids after temporomandibular joint arthrocentesis.

Method and materials: Studies were searched on PubMed, Embase, Web of Science, and Google Scholar up to 15th January 2024. Randomized controlled trials comparing hyaluronic acid with corticosteroids after TMJ arthrocentesis were included. The outcomes were pain and maximal mouth opening.

Results: Ten articles corresponding to nine randomized clinical trials were included. There was no statistically significant difference in pain scores at 1 week (mean difference [MD] -0.30, 95% CI -1.25 to 0.65, I2 = 0%), 1 month (MD -0.55, 95% CI -1.23 to 0.13, I2 = 0%), and 6 months (MD -0.57, 95% CI -2.10 to 0.96, I2 = 58%) between the two groups. However, pain scores were found to be significantly lower in the hyaluronic acid group at 3 months (MD -1.07, 95% CI -1.84 to -0.31, I2 = 0%). No statistically significant difference was noted in maximal mouth opening at 1 week (MD 0.78, 95% CI -1.79 to 3.35, I2 = 0%), 1 month (MD 0.32, 95% CI -1.83 to 2.46, I2 = 0%), and 3 months (MD -0.41, 95% CI -3.90 to 3.07, I2 = 0%) between the two groups. Descriptive analysis for studies not included in the meta-analysis also presented similar results.

Conclusions: Low-quality evidence suggests that both intra-articular hyaluronic acid and corticosteroids have similar efficacy in improving pain scores and maximal mouth opening after temporomandibular joint arthrocentesis.

Objective: Oral cancer examinations seek to clinically identify early oral cancers and discover premalignancies prior to their progression to invasive cancer.

Method and materials: A cross-sectional study was conducted between April and August 2017 to explore and quantify the diagnostic approach used by United States (US) general dental practitioners following discovery of an oral lesion suspicious for malignancy/premalignancy. US licensed general dental practitioners who were clinically active members of the US National Dental Practice-Based Research Network were eligible to participate. Data for analysis were obtained via two questionnaires.

Results: The majority of participants were males, practiced full-time, had a suburban primary practice, were born during the 1950s, and graduated dental school in the 1980s or 2000s. After identifying an oral lesion suspicious for premalignancy/malignancy, the next action of most general dental practitioner respondents (65.4%) was to refer the patient for consultation/biopsy. Most general dental practitioners (87.2%) referred to an oral and maxillofacial surgeon; 22% of general dental practitioners reported personally biopsying suspicious lesions. There was a relatively weak association between completing an Advanced Education in General Dentistry or General Practice Residency and subsequently personally performing biopsies on patients with oral lesions suspicious for malignancy/premalignancy (OR 1.33, P = .06). Most written referrals took place electronically and often included information, including lesion location (87.0%), lesion sign/symptoms (85.3%), lesion history (83.9%), radiographs (59.3%), medical history (50.6%), dental history (48.8%), and photographs (42.4%). When a referral biopsy was performed, referring clinicians were most frequently informed of the findings via a written report (96.7%, when positive for malignancy/premalignancy, and 95.4% when negative).

Conclusion: A snapshot is presented of current actions taken by US general dental practitioners following the discovery of oral abnormalities suspicious for premalignancy/malignancy.

Objective: This prospective case series aimed to clinically evaluate the bleaching effect, spontaneous tooth sensitivity and variation in the thermal sensation threshold of different groups of teeth undergoing in-office bleaching.

Method and materials: Ten patients received conventional bleaching treatment: 35% hydrogen peroxide with 3 bleaching sessions of 45 minutes, evaluating color change (ΔE and ΔE00), whitening index (WID), and tooth sensitivity (VAS). Thermal stimulus-generating devices were used to simulate sensitivity caused by low temperatures through Quantitative Sensory Tests (QST). Analyses were conducted individually on different teeth groups (n=20) (lower incisors LI, upper incisors UI, canines C, upper first premolars PM).

Results: Regarding color change, LI and UI did not statistically differ from each other but showed significant difference and greater bleaching potential compared to C and PM (P =.018). Regarding sensitivity, LI and UI presented the highest spontaneous sensitivity values (P =.032), while PM did not display painful symptoms, also observed in provoked sensitivity analysis (P =.025).

Conclusions: The general analysis of the results indicates that the tooth type responds differently to the whitening treatment, both in relation to the aesthetic benefit and the occurrence of tooth sensitivity. It was observed that lower incisors reach the degree of chromatic saturation before canines and premolars, in addition to presenting greater bleaching sensitivity. Personalizing the treatment, based on prior knowledge of the degree of saturation, anatomical factors and the risk of sensitivity, can provide considerable advantages in the whitening technique.
