A 61-year old Chinese female was referred from a general private practitioner for persistent buccal abscess after completion of root canal treatment tooth 37. On clinical examination, 37 presented with metal-ceramic crown (CMC) 2mm gingival recession noted at the region. The overlying amalgam core overhanging on distal and grade 2 mobility. CMC have no contact point distal. Tooth not tender to ...

Physiologic drift of teeth requires remodeling alveolar bone at the tooth socket wall. Remodeling must be regulated so that collagenous attachments are maintained as new tooth positions are established. Thus, alveolar remodeling must occur coincident to remodeling of the Sharpey’s fibers which are embedded within that bone. Studies suggest that these fibers are severed at resorptive sites on th...

Deciduous teeth exfoliate as a result of apoptosis induced by cementoblasts, a process that reveals the mineralized portion of the root while attracting clasts. Root resorption in deciduous teeth is slow due to lack of mediators necessary to speed it up; however, it accelerates and spreads in one single direction whenever a permanent tooth pericoronal follicle, rich in epithelial growth factor ...

Alveolar ridge resorption has long been considered an unavoidable consequence of tooth extraction. While the extent and pattern of resorption is variable among individuals, there is a progressive loss of ridge contour as a result of physiologic bone remodeling. Over the long term, prosthodontic complications, loss of function, and inadequate bone for the placement of dental implants may result....

A 72-year-old woman presented with multiple periapical lesions and resorption of teeth in a single quadrant 17 years after an attack of herpes zoster (shingles) of the maxillary division of the trigeminal nerve. It is possible that cases of tooth resorption that were previously classified as idiopathic may have a viral aetiology and we suggest that these patients should be asked about a previou...

AIM To address the indications, contraindications, surgical procedure, complications following treatment, factors influencing the results and success rate of intentional replantation procedure. BACKGROUND Intentional replantation is extraction of a tooth to do extraoral root canal therapy, curettage of apical lesion when present, and its replacement in its socket. It has been proposed as an a...

The purpose of this study was to assess the effects of the administration of zoledronic acid (ZA) during orthodontic movement in rats. A hundred and twenty male Wistar rats were applied force of 30 cN with spring closed nickel-titanium to move the upper right first molar to mesial. In the Control Movement group (CM), only tooth movement was performed; the Control Acid Zoledronic group (CAZ) rec...

BACKGROUND Invasive cervical resorption (ICR) is not well understood by the professional, being misdiagnosed, leading to inappropriate treatment and unnecessary loss of tooth. INTRODUCTION ICR is defined as a localized process of resorption, which begins in the cervical area of the tooth, just below the epithelial junction and above the ridge crest in the area of the connective tissue inserti...

We examined effects of local and whole body irradiation before tooth extraction on appearance and differentiation of osteoclasts in the alveolar bone of rat maxillary first molars. Wistar rats weighting 100 g were divided into three groups: non-irradiation group, local irradiation group, and whole body irradiation group. In the local irradiation group, a field made with lead blocks was placed o...

The pathologic resorption of bone in the anatomic area of a multirooted tooth where the roots diverge is furcation invasion. Literature review on its treatment modalities is discussed In detail in this paper.
