Tomographic Evaluation of the Internal Adaptation for Recent Calcium Silicate-Based Pulp Capping Materials in Primary Teeth.

Biomed Res Int 2021 8;2021:5523145. Epub 2021 May 8.

Restorative Dentistry Department, Faculty of Dentistry, King Abdulaziz University, P.O. Box 80209, Jeddah 215-89, Saudi Arabia.

Objectives: To evaluate the internal adaptation of recent pulp capping materials (TheraCal and Biodentine) relative to MTA when used as indirect pulp capping for primary teeth.

Materials And Methods: Thirty primary molars were randomly allocated into three groups, group (A) was TheraCal, group (B) was Biodentine, and MTA was the control group (C). A standardized round class-V cavity (1.5 mm diameter and 2 mm depth) was prepared using a milling machine on the buccal surface of each tooth with the pulpal floor located on the dentin. Then, pulp-capping materials were applied. Finally, all teeth were restored by composite restoration. The internal adaptation of the pulp-capping materials to the dentinal surface was investigated by microcomputed tomography (Micro-CT) to determine the internal gap volume, and by optical coherence tomography (OCT) to determine the high-intensity reflection of light from the floor.

Results: Based on Micro-CT findings, TheraCal showed significantly higher internal gap volume than both MTA and Biodentine ( < 0.001), while MTA and Biodentine did not show a significant difference in the gap volume. Based on the OCT findings, TheraCal showed a significantly higher intensity of light reflection than both MTA and Biodentine ( < 0.001); however, there was no significant difference between MTA and Biodentine. Pearson's correlation test showed that there was a strong positive correlation between Micro-CT and OCT ( = 0.686, = 30, < 0.001).

Conclusions: Biodentine and MTA showed a comparable result in terms of their internal adaptation on the dentinal surface of the primary teeth, and both were better than TheraCal. There is a moderate to a strong positive correlation between Micro-CT and OCT in the measurement of internal adaptation of the tested pulp capping materials. OCT can be helpful and beneficial for the clinical setting and allow dentists to screen and evaluate restorations during follow-up.

Information seeking behaviour of dental trauma patients and their parents.

Dent Traumatol 2020 Dec 15;36(6):590-597. Epub 2020 Jul 15.

Unit of Paediatric Dentistry, UCL Eastman Dental Institute, London, UK.

Background And Aim: Dental trauma is a common public health issue that can be associated with high costs and lifelong treatment. Children and parents should have the correct information regarding its management to reduce the potential long-term sequelae. Understanding their information seeking behaviour is therefore important to ensure that they are able to access, understand and retain the relevant information. The aim of this study was to investigate (a) the different ways that patients undertaking treatment for dental trauma, and their parents, look for relevant information, (b) their information needs, and (c) their preferred format of information.

Material And Methods: This was a two-phase study: Phase I involved in-depth interviews with 10 patients who were currently undergoing treatment for dental trauma, and 11 parents. In phase II, the themes and sub-themes identified from the interviews were used to develop patient and parent questionnaires, which were distributed to all trauma patients and parents who fulfilled the inclusion criteria and who were attending the dental clinics from March to May 2014.

Results: Patients and parents had different concerns immediately following the trauma, during treatment and in the long term, and they wanted different forms of information to answer their concerns. Reliability was the main issue about trusting the information available in the Internet, social media and other online sources. Therefore, patients preferred to obtain information verbally from their dentist, while parents preferred written information.

Conclusion: Patients and parents have different information needs, and these also vary at different stages of treatment. It is therefore important to customize the way information is provided for each group accordingly.

Long-term effectiveness of intralesional triamcinolone acetonide therapy in orofacial granulomatosis: an observational cohort study.

Br J Dermatol 2014 Apr;170(4):794-801

University College London/University College London Hospital, Eastman Dental Institute and Hospital, Oral Medicine Unit, 256 Gray's Inn Road, London, WC1X 8LD, U.K; NIHR Biomedical Research Centre at University College London Hospital NHS Foundation Trust and University College London, Maple House Suite A 1st floor, 149 Tottenham Court Road, London, W1T 7DN, U.K.

Background: It has been suggested that intralesional triamcinolone injections represent a safe and effective therapeutic strategy in controlling the permanent disfiguring swelling of orofacial granulomatosis (OFG). However, robust supporting evidence is lacking, due to the variable and inconsistent design of available studies.

Objectives: To investigate whether a standardized regimen of intralesional triamcinolone has beneficial long-term effects on orofacial swelling of OFG. We also studied potential associations with a number of prognostic factors.

Methods: We designed a retrospective observational study of a homogeneous cohort of 22 well-phenotyped patients with OFG. The primary outcome was defined as a statistically significant decrease in post-treatment disease severity. Statistically significant association with prognostic factors was the secondary outcome. Statistical analysis included Wilcoxon signed-rank tests and logistic regression.

Results: Compared with pretreatment, there were statistically significant decreases in disease severity scores at all time points until 48 months post-treatment (P < 0·01). Logistic regression analysis showed there was no independent prognostic variable of statistical significance (P > 0·05). The majority of patients (14/22, 63·6%) received one course of intralesional triamcinolone and did not experience disease recurrence. The mean disease-free period after the first course of intralesional therapy was 28·9 ± 18 months (95% confidence interval 28·7-29·1). No adverse effects were reported.

Conclusions: This is the first study to have employed robust cohort methodology and sound statistics to demonstrate long-term effectiveness of intralesional triamcinolone in controlling the disfiguring swelling of OFG. Because of limitations inherent in observational studies, further research in the form of randomized case-control trials is needed to confirm the present findings.
