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...

The aim of the present review was to systematically present the clinicopathological data of desmoplastic ameloblastoma (DA) from articles published in the literature. A comprehensive search of the databases (PubMed, Medline, SCOPUS, Web of Science, and Google Scholar) for published articles on DA was conducted. A total of 238 cases were identified and analyzed from 76 published papers. DA showed a slight male predilection (male: female=1.07:1) with a predominance in the fourth and fifth decades of life. Mandibular involvement (52...

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...

BACKGROUND: The study was designed to evaluate and compare the rest periods of 4 and 6 weeks for healing of orthodontically induced root resorption craters. METHODS: The study was conducted with a split-mouth design, with the right and left mandibular first premolars of 14 subjects serving as the two groups of the study. The right premolars constituted group A and the left ones, group B. Intrusive force was applied on these teeth for a period of 6 weeks, followed by retaining the teeth for 4 weeks (group A) and 6 weeks (group B) as rest periods before extraction...

OBJECTIVE: Root resorption is a complication of orthodontic treatment and till date, there is a dearth of information regarding this issue. The aim of this study was to determine whether the expression of transforming growth factor-β1 (TGF-β1, an inflammatory cytokine) is related to orthodontic force. Moreover, if associated, the expression level may be helpful in differential diagnosis, control and ultimate treatment of the disease. MATERIALS AND METHODS: In this experimental study, a total of 24 eight-week-old male Wistar rats were selected randomly...

Tooth is made of an enamel-covered crown and a cementum-covered root. Studies on crown dentin formation have been a major focus in tooth development for several decades. Interestingly, the population prevalence for genetic short root anomaly (SRA) with no apparent defects in crown is close to 1.3%. Furthermore, people with SRA itself are predisposed to root resorption during orthodontic treatment. The discovery of the unique role of Nfic (nuclear factor I C; a transcriptional factor) in controlling root but not crown dentin formation points to a new concept: tooth crown and root have different control mechanisms...

Lactobacillus probiotics have been investigated in periodontitis. However, the effects of the genus Bifidobacterium on periodontitis are hardly known. This study evaluated the effects of the probiotic (PROB) Bifidobacterium animalis subsp. lactis (B. lactis) HN019 as an adjunct to scaling and root planing (SRP) in rats with experimental periodontitis (EP). At baseline, 32 rats were assigned to 4 groups: C (control), PROB, EP-SRP and EP-SRP-PROB. In groups EP-SRP and EP-SRP-PROB, the mandibular first molars of the animals received a ligature...

Injuries to the teeth and surrounding structures are relatively common. Although traumatic injuries caused by falls or activities related to sports are widely discussed, the same cannot be said regarding accidents arising from non-professional extraction of primary teeth. The present study reports a 6-year-old male child who underwent mandibular alveolar bone fracture during non-professional extraction of his central lower left incisor at home, performed by his 30-year-old aunt. The root of the tooth was with an irregular physiological resorption, which acted as a lever component for the mechanical force applied, leading to bone fracture...

OBJECTIVE: Periapical periodontitis results in alveolar bone resorption around the root apex. During the progression of inflammation, host cells release various inflammatory mediators and pro-inflammatory cytokines through immune responses. However, the pathological mechanisms associated with periapical bone destruction remain unclear. This study was objected to identify differentially regulated proteins in periapical periodontitis via a quantitative proteomics approach using isobaric tags for relative and absolute quantification (iTRAQ) labelling of peptides...

INTRODUCTION: One of the common findings encountered by the clinician at the end of orthodontic treatment is the apical root resorption. Root resorption occurs to various degrees. A severe form of root resorption is characterized by shortening of root for more than 4 mm or more than one-third of the total tooth length. A low incidence rate of resorption is observed based on radiographic findings for the diagnosis of root resorption, panoramic radiography, and periapical radiography. Hence, we evaluated the accuracy of panoramic radiographic films for assessing the root resorption in comparison with the periapical films...

Systemic sclerosis (SSc) is a complex, chronic, and progressive autoimmune disease. SSc causes bone resorption of mandible and distal phalanges of fingers through a known mechanism, and it has also been pointed out as a possible cause of apical root resorption of teeth, because tooth resorption is regulated by similar mechanisms to those controlling bone resorption. The objective of this article was to report the first case in the literature of external cervical resorption (ECR) as an oral manifestation of SSc...

This paper presents a case of severe root resorption of the maxillary central incisors in an 18-year-old woman who was referred for orthodontic treatment of irregular dental arches. A detailed history revealed that she used to play the block flute on an everyday basis during childhood. Against all warnings, she continued to firmly press her teeth into the mouthpiece of the instrument. Impressions of the upper central incisors were clearly visible on the instrument. Although it is well known that excessive occlusal forces can result in root resorption, to the authors' knowledge, this case involves one of the first reported occurrences of extensive root resorption that was most likely caused by playing a wind instrument during childhood...
