Frequency of Contamination on Used Healing Abutments after Sterilization: An In Vitro Study.

Purpose: To determine and compare the frequency of contamination on different sites of healing abutments (HAs) after sterilization with Phloxine B dye on unused and used HAs after sterilization.

Materials And Methods: A total of 60 HAs were divided into two test groups: (1) used and sterilized and (2) a control group (unused). The test group was evaluated for contamination after sterilization; the control group did not undergo any procedure.

Effect of different access cavity designs on fracture toughness of endodontically treated teeth: a systematic review and network meta-analysis.

Objective To compare the effect of different endodontic access cavities on fracture toughness of extracted endodontically treated human teeth.Data/sources An electronic literature search was performed in seven databases as well as hand search until September 2020. Risk-of-bias tool was used to evaluate the quality of included studies.

Effect of full sulcular versus papilla-sparing flap on periodontal parameters in periradicular surgeries: A systematic review and meta-analysis.

Background: Access to apical root canal system is gained after flap elevation using various incision techniques. Soft-tissue healing after periradicular surgery may include gingival recession, papilla recession, changes in probing depth, and clinical attachment loss.

Objective: The objective of this study was to compare the effect of full sulcular flap design versus papilla-sparing flap design on the periodontal parameters in periradicular surgeries.

A Variant of the Current Dens Invaginatus Classification.

Endodontic treatment of maxillary incisors may be considered straight forward. However, in some instances, they may exhibit aberrant morphology. One of these rare variations in tooth morphology is dens invaginatus.

Comparison between conventional and piezocision-assisted orthodontics in relieving anterior crowding: a systematic review and meta-analysis.

Background: Prolonged duration of orthodontic treatment is of great concern and poses risks to the teeth and surrounding tissues. Orthodontic tooth movement can be accelerated by introducing regional insult. Evidence suggests piezocision to be minimally invasive and clinically effective.

Decalcification and bond failure rate in resin modified glass ionomer cement versus conventional composite for orthodontic bonding: A systematic review & meta-analysis.

Background: Demineralized white spot lesions (DWSLs) are one of the unfavourable effects of orthodontic treatment. Resin modified glass ionomer cement (RMGIC) was introduced to reduce its occurrence.

Objective: The study aimed to determine the incidence of DWSLs as primary objective and bond failure rate in brackets bonded with RMGIC versus conventional composite (CC) as secondary objective.

Role of three-dimensional printing in periodontal regeneration and repair: Literature review.

Three-dimensional (3D) printing is the process of building 3D objects by additive manufacturing approach. It is being used in endodontics, periodontology, maxillofacial surgery, prosthodontics, orthodontics, and restorative dentistry, but our review article is focused on periodontal application. A detailed literature search was done on PubMed/Medline and Google Scholar using various key terms.

Management of immature necrotic permanent teeth with regenerative endodontic procedures - a review of literature.

Immature necrotic permanent tooth presents a distinctive challenge for the endodontist. Various treatment modalities have been employed to create hard tissue barrier at the apex, which includes non-vital pulp therapy with calcium hydroxide, apexification with mineral trioxide aggregate, pulp revascularisation and regeneration. Regenerative endodontics is a novel modality which involves physiological replacement of the damaged structures of tooth like dentin, root and cells of the pulp-dentin complex.

Most effective method for the management of physiologic gingival hyperpigmentation: A systematic review and meta-analysis.

Background And Aim: Gingival hyperpigmentation is an esthetic problem. The aim of the present study was to identify most effective treatment modality for managing generalized physiological gingival pigmentation.

Materials And Methods: A systematic review and meta-analysis were done (1919 to October 2018) using PubMed, CINHAL, Dental and Oral Science, and manual searches.

Vertical Ridge Gain with Various Bone Augmentation Techniques: A Systematic Review and Meta-Analysis.

Purpose: The aim of this systematic review was to determine the most effective alveolar augmentation technique for vertical bone gain.

Materials And Methods: A systematic search to select clinical trials and retrospective studies done on patients with reduced vertical bone height was conducted. The intervention of interest was autogenous block graft done compared to procedures such as distraction osteogenesis (DO), particulate grafting, block plus particulate grafting with titanium mesh, and tent pole technique in systematically healthy adult patients age 18 and older.

Visual And Microscopic Evaluation Of The Surface Alterations In The Protaper Files After Single Clinical Use.

Background: Different studies have been conducted in which defects of Ni-Ti files were reported after multiple usages but limited data is available regarding the defects in the rotary Ni-Ti files subjected to single clinical use. The objective of this study was to determine the frequency of surface defects caused by fatigue in the rotary ProTaper files after single clinical use assessed with visual and microscopic examination methods.

Methods: A cross-sectional study was conducted in the dental clinics of The Aga Khan University Hospital, Karachi, Pakistan.

Prosthetic rehabilitation of edentulous mandible with two-implant retained fixed hybrid prosthesis: A case report.

Removable complete dentures have been the most costeffective treatment option for edentulous jaws since decades. However, certain problems are encountered by the patients such as stability of the lower dentures resulting in poor masticatory efficiency. Ridge resorption and inadequate bony support are the long-term complications comprising the stability of the denture and patient finding it difficult to control denture movement during speaking and eating reducing patient compliance.

Assessment of contamination on sterilised dental burs after being subjected to various pre-cleaning methods.

Objective: To determine the effectiveness of different pre-cleaning methods by determining frequency and site of contamination on the sterilised dental burs using Phloxine B dye.

Methods: The in-vitro experimental study was conducted from June to August 2017 at dental clinics of Aga Khan University Hospital Karachi. Diamond dental burs were selected and divided into two control and four test groups.
