Pulp Stone Formation Following Fixed Orthodontic Treatment: A Panoramic Radiographic Comparison of Extraction and Non-Extraction Approaches.

Objective: The impact of orthodontic forces on pulp stone formation has been the focus of several studies. Given that orthodontic extractions typically involve the application of greater forces to the teeth, the aim of this study was to compare the extent of pulp stone formation in the molar teeth of patients undergoing orthodontic treatment with and without extractions.

Material And Methods: In this retrospective observational study, panoramic radiographs of 80 orthodontic patients taken between 2014 and 2020 (equally divided into extraction and non-extraction groups) who had a full set of permanent molars were analyzed before and after orthodontic treatment to assess the formation of pulp stones in the pulp chambers of the molar teeth (640 molars).

Effect of Different Forms of Fluoride Application on Surface Roughness of Rhodium-Coated NiTi Orthodontic Wires: A Clinical Trial.

This study aimed to assess the effect of different forms of fluoride application on surface roughness of rhodium-coated nickel-titanium (NiTi) orthodontic wires. This randomized clinical trial was conducted on 15 patients randomly divided into three groups: toothbrush with Oral-B toothpaste only, Oral-B toothpaste, and daily mouthwash, Oral-B toothpaste, and sodium fluoride gel. The surface roughness indices of orthodontic wires including arithmetic mean height (Sa), root mean square height, root mean square gradient, developed interfacial area ratio (Sdr) and maximum surface height were measured by atomic force microscopy at baseline and after 6 weeks of application in the patients' mouths.

Antifungal Effect of Ginger Essential Oil Spray on Adhering to Self-Cure Acrylic Plates.

The present study aimed to evaluate the efficacy of ginger essential oil spray for elimination of () adhering to self-cure acrylic plates. In this experimental study, 120 self-cure acrylic discs were contaminated with and randomly divided into four main groups: exposure to ginger essential oil, nystatin (positive control), distilled water (negative control), and no exposure. The minimum inhibitory concentration (MIC) of ginger oil and nystatin was determined by the microdilution test.

A Cross-Sectional Study of Labial Bone and Covering Soft Tissue in Maxillary Anterior Segment: A Dilemma in Orthodontics.

Purposes: The thickness of the buccal bone and its covering gingiva is pivotal in determining the prognosis of implant therapy as well as fixed orthodontic appliances, especially nonextraction treatments. The purpose of this study was to evaluate the buccal bone thickness and covering soft tissue in the maxillary anterior segment.

Methods: This study measured the hard tissue thickness at 2 and 5 mm more apical from the crest and at the root apical apex, as well as the distance from the CEJ to the alveolar crest, using 80 CBCT images divided into three age groups.

Clinical comparison between Multi-Stranded Wires and Single strand Ribbon wires used for lingual fixed retainers.

Background: Long-term retention with fixed retainers with a high success rate seems to be a reasonable solution to minimize or prohibit relapse of orthodontic treatment.

Methods: Two hundred sixty patients between 13 and 30 years old were recruited for this study. The 0.

Anthropometric Facial Changes After Orthognathic Surgery and Their Relation With Oral Health Related Quality of Life.

Purpose: The aim of the present study was to determine the impacts of orthognathic surgery on soft tissue on frontal and profile views and their relation with patient's quality of life.

Methods: Twenty-nine patients with severe skeletal class III malocclusion who were candidate for bimaxillary orthognathic surgery consisted of 1-piece Lefort I surgery with bilateral sagittal split osteotomy were selected. Oral health was assessed by short from of Oral Health Impact Profile-14 questionnaire.

Decreased bone density induced by antiepileptic drugs can cause accelerated orthodontic tooth movement in male Wistar rats.

Purpose: The aim of the present study was to evaluate the effect of the carbamazepine and valproic acid on orthodontic tooth movement in male Wistar rats.

Methods: Evaluation of tooth movement after 21 days of drugs infusion was carried out by feeler gauge. Bone densitometry on lateral cephalograms was conducted on days 1 and 21.

Effect of Fluoxetine Consumption on Orthodontic Tooth Movement in Rats.

Objectives: Fluoxetine is a selective serotonin re-uptake inhibitor (SSRI) widely used for depression, bipolar disorder, anxiety and obsessive-compulsive disorder. The aim of this study was to assess the effect of fluoxetine on orthodontic tooth movement (OTM) in rats.

Materials And Methods: Forty-five male Wistar rats were randomly divided into three groups namely the control group (no medication), saline and fluoxetine dissolved in saline.

Effect of In-Office Carbamide Peroxide-Based Tooth Bleaching System on Wear Resistance of Silorane-Based and Methacrylate-Based Dental Composites.

Objectives: Several studies have assessed the characteristics and properties of silorane-based composites and adhesive systems. Considering the extensive application of tooth-whitening agents, possible deteriorative effects of tooth bleaching agents on these restorative materials must be studied. The aim of this study was to evaluate the effect of an in-office carbamide peroxide-based tooth bleaching agent on the wear resistance of a silorane-based and a conventional microhybrid dimethyl methacrylate-based dental composite with two different application times.

Oral Impacts on Daily Performance in 20- to 50-yearolds Demanding Dental Care in Tehran, Iran: Association with Clinical Findings and Self-reported Health.

Purpose: To determine the prevalence and intensity of oral impacts on daily performance in 20- to 50-year-olds attending the dental clinic at Tehran Dental School and to investigate the association between the Oral Impacts on Daily Performance (OIDP) score, self-reported oral and general health and clinical findings of oral health.

Materials And Methods: The study population comprised 20- to 50-year-olds attending the dental clinic before receiving any treatments. Data were collected using questionnaire-led interviews and clinical examinations.

Step-by-step full mouth rehabilitation of a nasopharyngeal carcinoma patient with tooth and implant-supported prostheses: A clinical report.

This clinical report presents a 46-year-old man diagnosed with nasopharyngeal carcinoma with the chief complaint of masticatory and speech deficiency because of radiation therapy. After a period of controlling post radiation caries, the patient was rehabilitated with tooth and implant supported metal ceramic restorations following surgical and endodontic intervention.
