Fractal Dimension as a Tool for Assessment of Dental Implant Stability-A Scoping Review.

J Clin Med 2022 Jul 13;11(14). Epub 2022 Jul 13.

Department of General Dentistry, Medical University of Lodz, 92-213 Lodz, Poland.

A lot of modalities for assessing implant stability are available for clinicians, but they fail to assess trabecular changes as they are solely dependent on the operator's skills. The use of Fractal Dimension (FD) has evolved to be used as a measure for trabecular changes depicting implant stability before and after implant placement. The objective of this systematic review was to qualitatively analyse the available scientific literature describing the use of FD as a tool to measure implant stability on the basis of trabecular changes. An electronic search in PubMed, Web of Science and Scopus was carried out using relevant keywords, such as: fractal dimension; fractal analysis; dental implants; implant stability; osseointegration, etc. Studies reporting the use of FD as a tool to measure implant stability were included and subjected to qualitative analysis using ROBINS-I and Cochrane risk of bias assessment criteria. Fourteen studies were included in this review. Results showed that FD was found to be used solely as a measure of implant stability in seven studies, out of which six studies showed an increment in FD values. The majority of studies concluded with a statistical correlation between FD and respective other assessment methods used. FD may not serve as a sole indicator of implant stability; however, it can be used as an adjunct to conventional methods along with additional fractal factors.

Clinical Outcome and Comparison of Regenerative and Apexification Intervention in Young Immature Necrotic Teeth-A Systematic Review and Meta-Analysis.

J Clin Med 2022 Jul 5;11(13). Epub 2022 Jul 5.

Department of General Dentistry, Medical University of Lodz, 92-213 Lodz, Poland.

This systematic review aimed to evaluate interventions individually and compare the clinical outcome of young, immature teeth treated with regenerative endodontic therapy (RET) and apexification procedure. The protocol was registered with PROSPERO (International Prospective Register of Systematic Reviews), bearing the registration number CRD42021230284. A bibliographic search in the biomedical databases was conducted in four databases-PubMed, CENTRAL, EMBASE and ProQuest-using searching keywords and was limited to studies published between January 2000 and April 2022 in English. The search was supplemented by manual searching, citation screening and scanning of all reference lists of selected paper. The study selection criteria were randomized clinical trial, prospective clinical studies and observational studies. The search found 32 eligible articles, which were included in the study. The quality assessment of the studies was performed using the Cochrane risk of bias tool for randomized control trials and non-randomized clinical studies. The meta-analysis was performed using Review Manager software (REVMAN, version 5). The results indicated that a clinicians' MTA apexification procedure was more successful compared to calcium hydroxide. In RET, apical closure and overall success rate is statistically same for both apical platelet concentrates (APCs) and blood clots (BC). Both interventions have similar survival rates; however, RET should be preferred in cases where the root development is severely deficient, there is insufficient dentine and the tooth's prognosis is hopeless even with an apexification procedure.

Comparative evaluation of the effect of two pulpal medicaments on pain and bleeding status of mandibular molars with irreversible pulpitis post-failure of inferior alveolar nerve block: a double-blind, randomized, clinical trial.

PeerJ 2022 13;10:e13397. Epub 2022 May 13.

Department of Conservative Dentistry, Faculty of Dental Medicine, Universitas Airlingga, Surabaya City, East Java, Indonesia.

Background: Complete relief of pain due to irreversible pulpitis is challenging to obtain with analgesic medications. The high incidence of an inferior alveolar nerve block (IANB) failure makes it difficult for practitioners to perform endodontic treatment without implementing other anesthetic techniques, especially mandibular molars. The aim of this study was to compare efficacies of two different quantities of paraformaldehyde based pulpal medicaments to relieve the pain and control hyperemic pulp post-failure of IANB and supplementary technique in patients experiencing this symptomatic irreversible pulpitis in the permanent mandibular tooth.

Method: Eighty-two participants with severe pain pre-operatively (Heft Parker Visual Analogue Scale, VAS > 114 mm) were enrolled, and pain responses were recorded at different time intervals using the Heft Parker visual analogue scale. To the patients experiencing pain even after the administration of the standard IANB and supplemental intraligamentary injection, one of the two paraformaldehyde based pulpal medicaments was placed in the pulp chamber and sealed. Participants were recalled after 24-48 h (second visit) to assess pain and bleeding reduction.

Results: Results showed a significant decrease in pain severity and bleeding score post medicament placement ( < .05). Hence judicious use within a recommended period, pulpal medicaments can be considered safe.

Conclusion: Paraformaldehyde based pulpal medicament can be used as an alternative to manage pain in patients having severe irreversible pulpitis and hyperalgesia.

Are Survival Outcomes Different for Young and Old Patients with Oral and Oropharyngeal Squamous Cell Carcinoma? A Systematic Review and Meta-Analysis.

Cancers (Basel) 2022 Apr 8;14(8). Epub 2022 Apr 8.

Department of General Dentistry, Medical University of Lodz, 92-213 Lodz, Poland.

This systematic review and meta-analysis aims to address whether age can be a determinant of overall survival (OS), disease-free survival (DFS), recurrence, distant metastasis (DM) and second primary (SP) in surgically treated oral and oropharyngeal squamous cell carcinoma (OOPSCC). A total of 4981 cases and 44254 controls from 25 comparative observational studies were included in the analysis. A significantly better OS (matched subgroup analysis: OR 1.64; 95% CI 1.31-2.04, overall analysis: OR 1.48; 95% CI 1.09-2.01) was observed in young patients compared to older adults, with heterogeneity ranging from moderate to severe. Worse DFS (unmatched subgroup analysis OR 0.43; 95% CI 0.27-0.68) was observed in young patients compared to older adults with minimal to moderate heterogeneity. The frequency of recurrence (OR 1.49; 95% CI 1.10-2.02) and DM (OR 1.83; 95% CI 1.10-3.03) was significantly higher in the young patients, as found in unmatched and matched subgroup analysis, with the least heterogeneities. Young age can be considered as an independent prognostic factor for recurrence and distant metastases in OOP-SCC. Larger and methodologically robust observational studies with longer follow-up are needed to establish the definitive role of age as an independent prognostic factor on OS and DFS in OOPSCC.

Oral Health-Related Quality of Life in Children and Adolescents with a Traumatic Injury of Permanent Teeth and the Impact on Their Families: A Systematic Review.

Int J Environ Res Public Health 2022 03 6;19(5). Epub 2022 Mar 6.

Department of General Dentistry, Medical University of Lodz, 92-213 Lodz, Poland.

The aim of this systematic review was to evaluate the impact of a traumatic dental injury (TDI) of permanent teeth in children and adolescents on their oral health-related quality of life (OHRQoL) as well as on their families. A bibliographic search in the biomedical databases (PubMed, Cochrane Library, MEDLINE) was limited to studies published between January 2000 and February 2021. The study selection criteria were cross-sectional, case control, or prospective clinical studies, which analyzed TDI before and after the treatment of permanent teeth in healthy children and adolescent, assessed their OHRQoL, and were written in English. The search found 25 eligible articles that were included in the study. The quality assessment of the studies was performed using the quality assessment checklist for survey studies in psychology (Q-SSP). The results indicated that a TDI of permanent teeth strongly influences the OHRQoL of children and adolescents, and the timely-performed dental management of a TDI allows for preventing further biological and socio-psychological impacts. Sociodemographic status, economic status, parent's education, gender, age group, and type of schooling were determinants of the TDI impact on OHRQoL.

Effect of Sodium Hypochlorite Concentration on Electronic Apex Locator Reliability.

Materials (Basel) 2022 Jan 23;15(3). Epub 2022 Jan 23.

Department of Conservative Dentistry, School of Dentistry, Dental Research Institute, Pusan National University, Yangsan 50612, Korea.

This ex vivo study aimed to measure the performance of an electronic apex locator (EAL) in the presence of sodium hypochlorite irrigants with different concentrations. Two EALs (Root ZX Mini and Locapex 6) were used to locate the apical foramen in 10 extracted single-rooted teeth in the presence of 0.5%, 2.5% and 5% sodium hypochlorite. Visual working lengths were also determined using #10 K-file under a microscope before the electronic measurements were made. The performance of both EALs was compared for the electronic working lengths determined under the different concentrations of sodium hypochlorite. A multiple-way ANOVA and PLSD Fisher's test with an α risk fixed at 5% were conducted. There were no statistical differences in the working lengths determined by both EALs between the three groups with different concentrations of sodium hypochlorite and their visual control measurements. When a ± 0.5 mm margin was applied, the Root ZX Mini and the Locapex 6 presented 88% and 83% accuracy, respectively. Sodium hypochlorite concentration in irrigants does not affect the accuracy and reliability of either the Root ZX Mini or the Locapex 6. Electronic apex locators are reliable with any concentration of sodium hypochlorite irrigants.

The One-Year In Vivo Comparison of Lithium Disilicate and Zirconium Dioxide Inlays.

Materials (Basel) 2021 Jun 5;14(11). Epub 2021 Jun 5.

Department of General Dentistry, Medical University of Lodz, 251 Pomorska St, 92-213 Lodz, Poland.

The objective of the present study was to evaluate the one-year clinical performance of lithium disilicate (LD) and zirconium dioxide (ZrO) class II inlay restorations. Thirty healthy individuals who met the inclusion criteria were enrolled for the study. The patients were randomly divided into two study groups ( = 15): LD (IPS e.max press) and ZrO (Dentcare Zirconia). In the ZrO group, the internal surfaces of the inlays were sandblasted and silanized with Monobond N (Ivoclar, Leichsteistein, Germany). In the LD group, the internal surfaces of the inlays were etched with 5% hydrofluoric acid. The ceramic inlays were cemented with self-cure resin cement (Multilink N). Clinical examinations were performed using modified United State Public Health Codes and Criteria (USPHS) after 2 weeks, 4 weeks, 6 months and 1 year. The one-year survival rate was evaluated. In total, one failure was observed in the ZrO group. The survival probability after 1 year for the ZrO inlays was 93%, and for the LD inlays was 100%, which was statistically insignificant. The differences between both groups for most USPHS criteria (except for colour match) were statistically insignificant. Within the imitations of the present study, the lithium disilicate- and zirconia dioxide-based inlays exhibited comparable clinical performances. However, the colour and translucency match was superior for the lithium disilicate restorations.

Effectiveness of Autologous Platelet Concentrates in Management of Young Immature Necrotic Permanent Teeth-A Systematic Review and Meta-Analysis.

Cells 2020 10 7;9(10). Epub 2020 Oct 7.

Department of Biomedical, Surgical and Dental Sciences, Università degli Studi di Milano, 20122 Milano, Italy.

The use of autologous platelet concentrates (APCs) in regenerative endodontic procedures is inconsistent and unclear. The aim of this meta-analysis was to evaluate the effectiveness of autologous platelet concentrates compared to traditional blood-clot regeneration for the management of young, immature, necrotic, permanent teeth. The digital databases MEDLINE, SCOPUS, CENTRAL, Web of Science, and EMBASE were searched to identify ten randomized clinical trials. The outcomes at postoperative follow-up, such as dentinal wall thickness (DWT), increase in root length (RL), calcific barrier formation (CB), apical closure (AC), vitality response (VR), and success rate (SR), were subjected to both qualitative synthesis and quantitative meta-analysis. The meta-analysis showed that APCs significantly improved apical closure (risk ratio (RR) = 1.17; 95% CI: 1.01, 1.37; = 0.04) and response to vitality pulp tests (RR = 1.61; 95% CI: 1.03, 2.52; = 0.04), whereas no significant effect was observed on root lengthening, dentin wall thickness, or success rate of immature, necrotic teeth treated with regenerative endodontics. APCs could be beneficial when treating young, immature, necrotic, permanent teeth regarding better apical closure and improved response to vitality tests.

Additive Effect of Platelet Rich Fibrin with Coronally Advanced Flap Procedure in Root Coverage of Miller's Class I and II Recession Defects-A PRISMA Compliant Systematic Review and Meta-Analysis.

Materials (Basel) 2020 Sep 27;13(19). Epub 2020 Sep 27.

Department of Biomedical, Surgical and Dental Sciences, Università degli Studi di Milano, 20122 Milano, Italy.

Aim: This systematic review and meta-analysis aims to assess the additive effect of leukocyte and platelet-rich fibrin (L-PRF) on coronally advanced flap (CAF) procedures in root coverage of Miller's class I and II gingival recession defects. Review methodology: A comprehensive search in MEDLINE (PubMed), Scopus and CENTRAL (the Cochrane Central Register of Controlled Trials), along with an additional hand search, provided eight randomized clinical trials to be included in this review. A total of 167 patients with 470 gingival recession defects were analyzed. A meta-analysis was carried out to assess the change in gingival thickness (GT), width of keratinized gingiva (WKG), root coverage percentage (%RC), clinical attachment level (CAL) and recession depth (RD) at all follow-ups between CAF alone and CAF + L-PRF groups for all included studies. A subgroup analysis was carried out based on recession type (single/multiple).

Results: Overall, a significant improvement in GT, CAL and RD was found when treated with CAF + L-PRF. There was a trend for a positive effect in terms of an increase in WKG when using L-PRF, especially in the treatment of single recession, though significance was not achieved ( = 0.08 overall). The results of heterogeneity among the subgroups were varied and were found to be greater than 91.3% for GT and 32.8% for WKG.

Conclusion: L-PRF when used in addition to CAF showed favorable results for the treatment of class I and II gingival recession defects.

Effects of Surface Treatments of Glass Fiber-Reinforced Post on Bond Strength to Root Dentine: A Systematic Review.

Materials (Basel) 2020 Apr 23;13(8). Epub 2020 Apr 23.

Department of General Dentistry, Medical University of Lodz, 92-213 Lodz, Poland.

The objective of this systematic review was to determine the influence of surface treatment of glass fiber posts on bond strength to dentine. Laboratory studies were searched in MEDLINE, PubMed, Embase, PubMed Central, Scopus, and Web of Science search engine. All authors interdependently screened all identified articles for eligibility. The included studies were assessed for bias. Because of the considerable heterogeneity of the studies, a meta-analysis was not possible. Twelve articles were found eligible and included in the review. An assessment of the risk of bias in the included studies provided a result that classified the studies as low, medium, and high risk of bias. The available evidence indicated that the coronal region of the root canal bonded better to the glass fiber post than apical regions. Phosphoric acid, hydrogen peroxide, and silane application enhance post's retentiveness. In light of the current evidence, surface treatment strategies increase the bond strength of glass fiber post to dentine. However, recommendations for standardized testing methods and reporting of future clinical studies are required to maintain clinically relevant information and to understand the effects of various surface treatment of glass fiber post and their bond strength with dentine walls of the root canal.

"Diabetes and gum disease: the diabolic duo".

Diabetes Metab Syndr 2014 Oct-Dec;8(4):255-8. Epub 2014 Oct 13.

Department of Periodontics and Oral Implantology, Institute of Dental Sciences, Siksha 'O' Anusandhan University, Bhubaneswar, Orissa, India.

Background: Diabetes and periodontitis have long been linked in the dental literature but have never been substantiated. Periodontitis is an oral infection affecting the tooth-supporting tissues. Although the etiology for this condition is bacterial plaque, the host immune response may also mediate destruction of the periodontal tissues. Diabetes mellitus is intricately related to the development, progression and severity of periodontitis. The literature is abundant with studies depicting this association.

Discussion: Diabetes mellitus (DM) is a complex disease with varying degrees of systemic and oral complications. The periodontium is also a target for diabetic damage. In recent years, a link between periodontitis and diabetes mellitus has been postulated. The present review highlights the relationship between diabetes mellitus and periodontitis. The potential mechanisms involved in the development of periodontitis in diabetic patients, influence of periodontitis on diabetes and the role of TNF-α, a prime inflammatory mediator linking both of them have been discussed.

Conclusion: Diabetes clearly increases the risk of periodontal diseases, and biologically plausible mechanisms have been demonstrated in abundance. Less clear is the impact of periodontal diseases on glycemic control of diabetes and the mechanisms through which this occurs. It is possible that periodontal diseases may serve as initiators or propagators of insulin resistance in a way similar to obesity, thereby aggravating glycemic control.

Cherubism with multiple dental abnormalities: a rare presentation.

BMJ Case Rep 2014 Oct 9;2014. Epub 2014 Oct 9.

Department of Paediatric Dentistry, Institute of Dental Sciences, Bhubaneswar, Odisha, India.

Cherubism is a progressive, hereditary fibro-osseous lesion exclusively affecting the jaw bones. It is caused by the abnormal functioning of osteoblasts and osteoclasts, leading to replacement of normal bone by cellular fibrous tissue and immature bone, which produces painless progressive growth of the jaw, with a round facial appearance. It was first described in 1933 by Jones as 'familial multilocular cystic disease of the jaws'. The term 'cherubism' was later coined to describe the rounded facial appearance resulting from jaw hypertrophy that was reminiscent of cherubs depicted throughout Renaissance art. The bony lesions generally occur at an early age, affect one or both jaws symmetrically, and grow progressively until puberty. Spontaneous regression is seen in most cases, although surgical re-contouring may be required for others for aesthetic reasons.

Primary diffuse large B-cell lymphoma in the anterior hard palate: A rare case report with review of literature.

J Oral Maxillofac Pathol 2014 Jan;18(1):102-6

Department of Oral and Maxillofacial Surgery, Institute of Dental Sciences, Bhubaneswar, Odisha, India.

Diffuse large B-cell lymphomas (DLBCLs) are defined as neoplasms of large transformed B cells, i.e. with nuclear diameter more than twice that of a normal lymphocyte. These account for 30-40% of all adult non-Hodgkin's lymphomas (NHL). Intraoral lymphomas are relatively rare and often difficult to diagnose in clinical settings. In this case report, we describe a case of primary DLBCL affecting the anterior part of the hard palate of an elderly male patient. DLBCL of anterior part of hard palate is yet to be reported in the English literature, even though DLBCL cases involving the posterior palate have been recorded, thus making the present case to be first of its kind. Emphasis has also been given on the subclassification, differential diagnosis and prognostic antibody factors determining the outcome of DLBCL.

Iatrogenic subcutaneous emphysema of endodontic origin - case report with literature review.

J Clin Diagn Res 2014 Jan 12;8(1):279-81. Epub 2014 Jan 12.

Associate Professor, Department of Oral Medicine and Radiology, Institute of Dental Sciences, S'O' A University , Bhubaneswar, Odisha, India .

Surgical emphysema is well known and many case reports have been published on this. Many authors have reported this as a complication post dentoalveolar treatment. Diffusion of air into facial planes and periorbital area during endodontic procedures has been rarely reported. The use of three way air syringe and forceful irrigation of root canal can lead to surgical emphysema of subcutaneous tissue planes in and around the teeth which are involved. This case report highlights one such complication seen during endodontic treatment, discusses aetiology, complications and conservative management of this dental office emergency.

Hemifacial microsomia: a series of three case reports.

J Clin Diagn Res 2013 Oct 5;7(10):2383-6. Epub 2013 Oct 5.

Lecturer, Department of Conservative Dentistry & Endodontics, Institute of Dental Sciences , Bhubaneswar, Odisha, India .

Hemifacial Microsomia (HFM) is an asymmetric craniofacial malformation which results in hypoplasia of the components of the first and second branchial arches. There can be various anomalies, which include conductive hearing loss which is caused by external and middle ear deformities. HFM is the second most common congenital facial anomaly which is seen after cleft lip/palate. For the pre-surgical evaluation of this anomaly, diagnostic imaging and classification of the facial structures, based on OMENS classification, is of prime importance. The management of this developmental malformation is multidisciplinary. We are presenting a series of three cases with diverse clinical and radiographic features which ranged from mild facial asymmetry and ear malformation to facial paralysis.

A Type III Dens Invaginatus with Unusual Helical CT and Histologic Findings: A Case Report.

J Clin Diagn Res 2012 Nov;6(9):1606-9

Lecturer, Department of Oral Medicine & Radiology, Institute of Dental Sciences, Siksha 'O' Anusandhan University , Bhubaneswar, Odisha, India.

Dens Invaginatus (DI) is a rare developmental anomaly which affects the tooth, which shows an infolding of enamel and dentine which extends into the pulp chamber and sometimes into the root. The aim of this case report was to describe its radiographic findings, to emphasize the bizarre morphology and the difficulties which are encountered in the diagnosis by using conventional radiographic techniques and the importance of computed tomography as a valuable diagnostic aid. Dens Invaginatus is clinically significant due to the possibility of an early pulpal involvement and the chronic periapical lesions are often associated with this anomaly without any clinical symptoms. Difficulties are encountered during the endodontic treatment, owing to the complex root canal anatomy; therefore, a proper radiologic evaluation by using different imaging modalities, is essential for its successful treatment.
