Thermoplastic materials are sensitive to humidity, temperature variations, enzyme activities, and cyclic loading. All these factors can cause changes the mechanical properties of material. The aim this study was determine influence different cleaning protocols on surface roughness orthodontic retainers. Samples two brands polyethylene terephthalate glycol (PET-G) material were exposed four prot...

BACKGROUND AND AIM: The mechanical removal of plaque by tooth brushing is the most effective way for prevention of caries and periodontal diseases. Some studies indicate that the design and shape of toothbrush could be the effective for this point. The aim of this study was to compare the efficacy of a Classic toothbrush with a Superbrush toothbrush in controlling plaque and gingival bleeding o...

Although foreign body (FB) ingestion is relatively common,ingestion of a toothbrush is rare. We are reporting on a 26-year old female who had accidentally swallowed a toothbrush, which was successfully removed via endoscopy using a polypectomy snare.

Introduction: Ingestion of a foreign body is a common problem among all age groups. Most of the foreign bodies in the pharynx are usually lodged at the level of cricopharynx. The diagnosis is based on history, clinical, and radiological examination. Most foreign-body ingestions are accidental, but there may be contributory factors such as mental disorder, alcoholism, and prison incarceration. T...

The aim of the present study was to evaluate the efficacy of manual and electric toothbrushes in plaque control in periodontal patients after proper instructions. Thirty six periodontal patients (mean age of 49 years, 21 females and 15 males) were included and completed the study (100% compliance). A single-blinded, randomized, controlled, cross-over clinical design was adopted, with the patien...

Introduction: Patients undergoing orthodontic treatment with fixed appliances have a challenging oral hygiene situation because brackets tenaciously trap food and other oral debris. Good plaque control is an important factor in the maintenance of dental health during fixed appliance therapy. Many different types of specially designed toothbrushes have been developed in recent years in order to ...

A 16-year-old girl inadvertently swallowed a toothbrush during attempted manual induction of emesis. The 20 cm toothbrush was successfully removed via overtube facilitated endoscopy using a retractable snare while the patient was sedated in the emergency department.

Ingestion of foreign bodies and impaction of food boluses frequently require endoscopic intervention. The most common ingested foreign bodies include food, fish and chicken bones, medication packaging, dentures, and coins [1]. An adult sized toothbrush is infrequently ingested, and a literature review of prior cases reveals adults who ingest it often have psychiatric co –morbidities [2]. There ...

PURPOSE To compare the safety and plaque removal efficacy, and subject preference of two electric toothbrushes in a single-blind, randomized, split-mouth study. MATERIALS AND METHODS The devices studied were the Braun Oral-B 3D Plaque Remover and the sonicare electric toothbrush. The 3D toothbrush combines the clinically proven oscillating/rotating action of the D9 with a sonic frequency puls...
