Dental hypersensitivity in individuals with cleft lip and palate: Origin and therapies.

J Dent Res Dent Clin Dent Prospects 2021 13;15(1):42-46. Epub 2021 Feb 13.

Postgraduate Center for Dentistry, CPO Uningá, Bauru, São Paulo, Brazil.

Dental hypersensitivity is due to the exposure of the dentin layer after wear of enamel or cementum, exposing the dentinal tubules and the nerve endings of odontoblasts within these tubules. The present study aimed to assess the factors related to dental hypersensitivity in individuals with cleft lip and palate and the most common therapy received. The medical records of 536 patients with cleft lip and/or palate (281 males, 255 females) with a mean age of 18 were analyzed in a single center. Read More

Tooth hypersensitivity associated with paresthesia after inferior alveolar nerve injury: case report and related neurophysiology.

Tae Min You

J Dent Anesth Pain Med 2021 Apr 31;21(2):173-178. Epub 2021 Mar 31.

Department of Advanced General Dentistry, School of Dentistry, Dankook University, Cheonan, Korea.

Inferior alveolar nerve (IAN) injury is usually caused by stretching or crushing of the neurovascular structures and postoperative intra-alveolar hematoma or edema after dental procedures. This results in paresthesia in the ipsilateral chin, lip (vermilion border, skin, and mucosa), and labial or buccal alveolar mucosa of the mandibular anterior teeth. However, there are no reports of sensory alterations in the teeth, especially tooth hypersensitivity, after IAN injury. Read More

A novel dentin bonding scheme based on extrafibrillar demineralization combined with covalent adhesion using a dry-bonding technique.

Bioact Mater 2021 Oct 23;6(10):3557-3567. Epub 2021 Mar 23.

National Clinical Research Center for Oral Diseases & Shaanxi Key Laboratory of Stomatology, Department of Prosthodontics, School of Stomatology, The Fourth Military Medical University, Xi'an, China.

Dentin bonding is a dynamic process that involves the penetration of adhesive resin monomers into the extrafibrillar and intrafibrillar demineralized collagen matrix using a wet-bonding technique. However, adhesive resin monomers lack the capacity to infiltrate the intrafibrillar space, and the excess water that is introduced by the wet-bonding technique remains at the bonding interface. This imperfectly bonded interface is inclined to hydrolytic degradation, severely jeopardizing the longevity of bonded clinical restorations. Read More

Electrical conductance for the detection of dental caries.

Cochrane Database Syst Rev 2021 03 16;3:CD014547. Epub 2021 Mar 16.

Dundee Dental School, University of Dundee, Dundee, UK.

Background: Caries is one of the most prevalent, preventable conditions worldwide. A wide variety of management options are available at different thresholds of disease, ranging from non-operative preventive strategies such as improved oral hygiene, reduced sugar diet, and application of topical fluoride, to minimally invasive treatments for early lesions which are limited to enamel, through to selective removal and restoration for extensive lesions. The cornerstone of caries detection is a visual and tactile dental examination, however, an increasing array of methods of caries lesion detection have been proposed that could potentially support traditional methods of detection and diagnosis.

Imaging modalities to inform the detection and diagnosis of early caries.

Cochrane Database Syst Rev 2021 03 15;3:CD014545. Epub 2021 Mar 15.

Division of Dentistry, School of Medical Sciences, Faculty of Biology, Medicine and Health, The University of Manchester, Manchester, UK.

Background: The detection and diagnosis of caries at the earliest opportunity is fundamental to the preservation of tooth tissue and maintenance of oral health. Radiographs have traditionally been used to supplement the conventional visual-tactile clinical examination. Accurate, timely detection and diagnosis of early signs of disease could afford patients the opportunity of less invasive treatment with less destruction of tooth tissue, reduce the need for treatment with aerosol-generating procedures, and potentially result in a reduced cost of care to the patient and to healthcare services.

The control of pain due to dentin hypersensitivity in individuals with molar-incisor hypomineralisation: a protocol for a randomised controlled clinical trial.

BMJ Open 2021 Mar 10;11(3):e044653. Epub 2021 Mar 10.

School of Dentistry, Universidade Metropolitana de Santos, Santos, SP, Brazil

Introduction: Dentin hypersensitivity (DH) is defined as high sensitivity of the vital dentin when exposed to thermal, chemical or tactile stimuli. Two mechanisms are required for the occurrence of DH: (1) the dentin must be exposed and (2) the dentinal tubules must be open and connected to the pulp. Molar-incisor hypomineralisation (MIH) is a qualitative abnormality of a genetic origin that affects tooth enamel and, in most cases, is accompanied by DH. Read More

Minimally invasive intervention in external cervical resorption: a case report with six-year follow-up.

Int J Burns Trauma 2020 15;10(6):324-330. Epub 2020 Dec 15.

Postgraduate Program in Dentistry of Health Institute of Nova Friburgo (PPGO-ISNF) from The Fluminense Federal University (UFF) Nova Friburgo, RJ, Brazil.

Root resorption consists of the loss of mineralized tissue (enamel, dentin, and cementum) of the inner or outer surface of the tooth due to the action of clastic cells. The correct diagnosis, the location, degree of tissue destruction, and the type of treatment are obstacles to the resolution of these lesions. The external cervical resorption is initiated in the amelocemental region progressively resorbing cementum, dentin, and enamel, constituting multiples ducts of resorption in an apical direction.
