Invasive cervical root resorption (ICR) is the reversible/irreversible loss of tooth structure in the connective tissue attachment zone with unclear etiology. In the present case a history of periodontal surgery was presumed to be the predisposing factor. Early diagnosis and proper treatment may lead to long-term retention of the tooth. The tooth is usually asymptomatic and diagnosis is commonly made as a result of a routine radiographic finding. Cone-beam computed tomography (CBCT) is extremely useful in diagnosis and treatment planning of ICR...

Cell-based partial pulp regeneration is one of the promising approaches to obtain newly formed functional dentin-pulp complex. It relies on the preservation of the healthy tissue while regenerating the damaged pulp. The aim of this study was to investigate whether this regenerative process could be achieved by implanting porcine dental pulp cells (pDPCs) in pulp defects in the minipig. By split-mouth model, self-assembling injectable nanopeptide hydrogel, with and without pDPCs, was implanted after cameral pulpotomy in premolars and molars...

BACKGROUND: Hormonal and enzymatic factors may render certain individuals more susceptible to orthodontically induced inflammatory root resorption (OIIRR). The objectives of this study are (1) to identify biochemical key markers in blood and saliva that may be correlated to the trend of extensive OIIRR and (2) to utilise these markers to predict a susceptible patient-receiving orthodontic treatment. METHODS: Nine patients (mean age 23 + 2.9 years) who had moderate to severe OIIRR that assessed via orthopantomograms and met the inclusion criteria were classified as the root resorption group (RRG)...

BACKGROUND: In setting goals for orthodontic treatment, determining the morphologies of the alveolar bone and maxillary incisor root is important for avoiding root resorption, dehiscence, and fenestration. This study aimed to analyze the configurational relationships among maxillary incisors, the alveolar border, and the incisive canal by cone-beam computed tomography (CBCT). METHODS: Cone-beam CT images of 93 orthodontic patients were evaluated for length of the incisive canal (L); angles between the palatal plane and the maxillary alveolar border (θ1), the incisive canal (θ2), and maxillary incisor (θ3); distance from the left maxillary incisor to the incisive canal (D); and cross-sectional areas of the incisive canal (CSAs) at three vertical levels...

BACKGROUND: Orthodontically induced iatrogenic root resorption (OIIRR) is an unavoidable inflammatory process. Several factors claimed to be related to the severity of OIIRR. Orthodontic forces cause micro-trauma to the periodontal ligament and activate a cascade of cellular events associated with local periodontal inflammation. The purpose of this split-mouth study were (1) to investigate the changes in cytokine profile in the gingival crevicular fluid (GCF) secondary to heavy orthodontic forces and (2) to compare the cytokine expression between participants showing high and low root resorption...

S Patel, F Foschi, F Mannocci, K Patel
This paper describes a novel 3-dimensional classification for external cervical resorption (ECR). The European Society of Endodontology and American Association of Endodontists & American Academy of Oral & Maxillofacial Radiology position statements advise that CBCT should be considered for the assessment and/or management of root resorption if it appears to be clinically amenable to treatment following clinical and conventional radiographic examination. The new classification takes into account the ECR lesion height (1: At CEJ level or coronal to the bone crest (supracrestal), 2: Extends into the coronal-third of the root and apical to the bone crest (subcrestal), 3: Extends into the mid-third of the root, 4: Extends into the apical-third of the root), circumferential spread (A: ≤ 90° B: ≤180° C: ≤270° D: >270°) and proximity to the root canal (d: Lesion confined to dentine, p: Probable pulpal involvement), thus classifying ECR in 3-dimensions...

Obesity is a wide-spread condition directly or indirectly connected with an increase in the prevalence of a variety of human diseases. It affects over 50% of the western overall population. In 2017, a thorough analysis of 204 studies on obesity and cancer revealed that the condition increases the risk of the following types of cancer: stomach, colon, rectal, bile duct, pancreatic, esophagus, breast, endometrial, ovarian, kidney and multiple myeloma. The first study aiming at establishing a connection between obesity and the rate of induced orthodontic tooth movement was conducted by Saloom et al; however, it could not effectively nor significantly reveal any direct influence or effect...

Invasive cervical resorption (ICR) is a type of external resorption that can involve the coronal, middle, and apical parts of the root in its advanced stages. The diagnosis and treatment of ICR depend on the extent of the resorption into the dentin. The treatment of advanced ICR is challenging, and these teeth have poor prognoses. This article describes 4 cases of class 4 ICR diagnosed by using cone-beam computed tomography and treated with a minimally invasive internal approach with sodium hypochlorite irrigation and calcium hydroxide dressing...

A pulpectomy requires the swift extraction of the inflamed tissue. Moreover, the speed of treatment is especially important in the case of uncooperative children. Conventional pulpectomies, however, often require an extended treatment period, which can therefore cause problems with such patients. Electrosurgical methods have been applied to pulpotomies for a number of years. However, to the best of our knowledge, no studies to date have assessed its application to pulpectomies. The aim of this study was to compare clinical and radiographic success rates over a 6-month follow-up period between conventional and electrosurgical pulpectomies...

Extracellularmatrix (ECM)-based scaffolds are important for their potential therapeutic application. Treated dentin matrix (TDM), a kind of ECM, seeded with allogeneic dental follicle stem cells (TDM/aDFC) provides a suitable inductive microenvironment for tooth root regeneration. Considering the limited sources, xenogeneic TDM (xTDM) is a possible alternative to allogeneic TDM; however, xTDM-based scaffold presents severe osteolysis and resorption lacunae causing regenerated tooth root failure. Immune response-induced excessive osteoclastogenesis plays a critical role in xenogeneic scaffold osteolysis and resorption...
