Instrument fracture in periodontal therapy: ethical disclosure and clinical management - a case report.

Periodontal instrument fractures are rare events in dentistry, with limited literature available on their occurrence and management. This case report highlights an incident involving the fracture of a periodontal sickle scaler blade during manual instrumentation for the removal of calculus. The fracture occurred during instrumentation on the mesial surface of the maxillary right second molar, and the separated blade was subsequently pushed into the sulcus. A radiographic assessment was performed to verify the precise location of the fractured segment. Following confirmation, the broken blade was subsequently retrieved using curved artery forceps. The case report highlights factors contributing to instrument fractures, emphasizing the importance of instrument maintenance, sterilization cycles, and operator technique. Ethical considerations regarding patient disclosure, informed consent, and instrument retrieval methods are well discussed. This case underscores the importance of truthful communication, the proper use of instruments, equipment maintenance in dentistry, and the significance of ongoing professional development to enhance treatment safety, proficiency, and ethical standards in dental care.

Evaluation Of Gingival Biotype And Recession Following Non-Surgical Periodontal Treatment Using 3-Dimensional Scan Methods.

The study evaluated the position of gingival margins in anterior teeth using clinical and 3-dimensional (3D) optical scanning method among patients subjected to non surgical periodontal treatment (NSPT). A single arm, longitudinal study was undertaken at the Archway Dental Center, University of Manchester, UK. History and clinical examination were done. Gingival recession, attachment loss (AL), and periodontal probing depth (PD) were recorded at baseline and 12-weeks follow-up. NSPT was done using hand and ultrasonic instruments. Impressions were made, the resultant gypsum models were scanned to generate 3D images. The change in the gingival level and thickness of facial gingiva were assessed. Out of eight patientsrecruited, three were lost to follow up. The 3D scan showed a poor correlation with the clinical assessment of gingival recession in anterior teeth following NSPT (r=- 0.0089). Recession did not improve after NSPT (p= 0.20).

Development and validation of scale for self evaluation of soft skills in postgraduate dental students.

OBJECTIVE: To develop and validate a soft skills questionnaire, and to use it for self-evaluation by postgraduate dentistry students. METHODS: The cross-sectional descriptive study was conducted at University College of Dentistry, , University of Lahore, Lahore, Pakistan, from February 2020 to April 2020 and comprised of residents from first to final year of training for either Masters in Dental Surgery or Fellowship of the College of Physicians and Surgeons Pakistan programmes. A soft skills questionnaire was generated and was validated through exploratory factor analysis of the elements and items of the questionnaire using SPSS 23. RESULTS: Of the 60 subjects, 37(61.7%) were MDS residents and 23(38.3%) were Fellowship residents. The mean age of the sample was 29.650±2.815 years, and 26(43.3%) subjects were males. The questionnaire was validated (p<0.001). Three domains measured the attitude of dentists, with 7 scenarios having 5 items per scenario. Both categories of trainees had high agreement in understanding and application of non-technical skills, with the exception of leadership skills. However, the difference between the groups was non-significant (p>0.05). CONCLUSIONS: A self-generated questionnaire was successfully validated.

A placebo-controlled randomized clinical trial of antibiotics versus probiotics as an adjuvant to nonsurgical periodontal treatment among smokers with Stage III, Grade C generalized periodontitis.

BACKGROUND: Probiotics are viable microorganisms, which if delivered in appropriate dose can provide health benefits. Lactobacillus reuteri (DM17938+ATCC PTA 5289) has been recommended as a safe choice for probiotics. The objective of this study is to compare the improvement in the periodontal parameters amongst smokers with generalized periodontitis with Stage III, Grade C treated with nonsurgical periodontal treatment (NSPT) to which either an antibiotics or probiotics were given as an adjuvant. METHODS: Sixty smokers with Stage III, Grade C generalized periodontitis were randomized in two groups after taking informed consent. Periodontal parameters including bleeding on probing (BOP), probing depth (PD), attachment loss (AL), gingival index (GI), and plaque index (PI) were recorded. Group 1 received (after NSPT and oral hygiene instructions) amoxicillin and metronidazole for 7 days and a placebo for probiotics for 30 days. Group 2 was provided (after NSPT and oral hygiene instructions) with one tablet of Lactobacillus reuteri probiotics (2 × 108 CFU) twice daily for 30 days and placebo antibiotics for 7 days. The periodontal parameters were recorded again at 1- and 3-month follow-ups as outcome variables. Mean, standard deviation, and confidence interval were reported using SPSS 20.0. RESULTS: A statistically significant clinical improvement in the PD, BOP, PI, and GI were observed in both the groups at 3-month follow-up. However, the AL remained unchanged in both the groups. CONCLUSIONS: Administration of probiotics and antibiotics along with NSPT yield statistically significant differences in PD and BOP from baseline to 3-month follow-up. However, between the group differences were not statistically significant for the periodontal parameters (AL, PD, and BOP).

Association of hard and soft tissue factors with gingival recession in orthodontically treated patients: A retrospective study.

INTRODUCTION: Orthodontic treatment is thought as a contributory factor in the development of recession. The objective of this study was to determine the factors associated with a gingival recession in patients who underwent orthodontic mechano-therapy. MATERIAL AND METHODS: A retrospective chart review of 72 post-orthodontic cases done at the dental clinics of Aga Khan University hospital that were treated from 2009 to 2017. After evaluating dental records patients were recruited based on inclusion and exclusion criteria. Patients were divided into two groups based on the presence or absence of gingival recession on posttreatment photographs. Patients in each group were further assessed on the following factors: (1) Lower incisor inclination (IMPA). (2) Tissue thickness on the facio-lingual dimension. (3) Alveolar bone height. (4) Alveolar bone thickness. RESULTS: The mean age of patients at the start of treatment was 16.56±5.66years. Gingival recession was found in 40.3% of our patients while 59.7% of patients had no recession found after orthodontic treatment. Univariable logistic regression was applied for factors associated with a gingival recession following orthodontic treatment which showed that the odds ratio of gingival recession in thin gingival biotype are 14.4 times more than in thick gingival biotype. Multivariable regression analysis showed that the cases had 10.2 times more recession in thin biotype than those in the thick gingival biotype while adjusting for pre- and posttreatment alveolar heights following orthodontic treatment and with a confidence interval [95% CI=2.69 to 38.40]. CONCLUSIONS: It was concluded from this study that 40% of patients developed gingival recession in one or more teeth during orthodontic treatment. Among different factors pre-treatment, gingival biotype of patients and male gender were the factors that were more associated with the development of gingival recession.

Effect of Apical Patency on Postoperative Pain: A Meta-analysis.

INTRODUCTION: This systematic review and meta-analysis assessed the available evidence regarding the effect of apical patency versus nonpatency on postendodontic pain in adult patients. METHODS: The study adhered strictly to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. PubMed, Scopus, MEDLINE via Ovid, Google Scholar, and the Web of Science databases were searched up to April 2018 to retrieve the most relevant studies. Two authors evaluated the studies for eligibility criteria and assessed the risk of bias using the Cochrane tool. The weighted means were calculated using a fixed effects model. When statistically significant (P < .1) heterogeneity was detected, a random effects model was used to assess the significance of treatment effects. RESULTS: Five studies were identified for this systematic review; 4 were included in the meta-analyses. Two studies revealed a low risk of bias, whereas 3 studies revealed a high risk of bias. Because of the significant heterogeneity between studies, a random effects model was used. The meta-analysis showed that the apical patency resulted in less postoperative pain compared with nonpatency, but the difference was not statistically significant. Moreover, no statistically significant difference was found with regard to analgesic consumption. CONCLUSIONS: Considering the limitations of this study, it was concluded that maintaining apical patency during routine endodontic treatment was not associated with an increased incidence of postoperative pain in adult patients.
