Superficial cervical plexus block on pain control in patients with temporomandibular joint internal derangement with headache: a retrospective cohort study.

Objectives: Temporomandibular disorders (TMDs) are a group of disorders with varied pathophysiology and clinical manifestations. Masticatory and cervical motor systems have a functional relationship. Superficial cervical muscles have greater hyperactivity in myogenous and mixed TMDs than in healthy individuals, demonstrating an abnormal pattern of contraction.

Retrograde peri-implantitis: evaluation and treatment protocols of a rare lesion.

Objective: Retrograde peri-implantitis (RPI) is defined as bone loss around an osseointegrated implant apex that usually appears within the first few months of its placement. This retrospective study aimed to evaluate the relationships between RPI and demographic factors, local bone and intraoral factors, and implant and surgery-related factors.

Method And Materials: A retrospective study was conducted in 116 patients with a total of 369 implants placed between January and June 2019.

Local and systemic factors associated with marginal bone loss around dental implants: a retrospective clinical study.

Objectives: The aim of this study was to determine the influence of patient-related systemic factors, local bone and intraoral factors, and implant-related factors on peri-implant marginal bone loss (MBL).

Method And Materials: The following data were collected from patients who received dental implants and were recalled for examinations at least 3 years after treatment completion: medical history, age, sex, habits, periodontal health, implant size and surface, surgical procedure, prosthesis type, implant failure, Plaque Index, and oral hygiene. MBL was investigated using both baseline and follow-up panoramic radiographs.

Transalveolar repositioning of an impacted immature permanent mandibular canine.

The purpose of this case report is to discuss the four-year follow-up of a transalveolar transplantation of an impacted immature permanent mandibular left canine. A nine year-old-boy was referred to the dental school because of a mandibular swelling associated with the impacted canine. Under local anesthesia, the tooth was extracted and transplanted in its own space, followed by a two-week orthodontic fixation.

Ki-67 and MCM-2 in dental follicle and odontogenic cysts: the effects of inflammation on proliferative markers.

The aim of this study was to investigate whether there is any association between inflammation and the expression of markers of cell cycle entry (Ki-67 and MCM-2) in dental follicle (DF) of asymptomatic impacted teeth and odontogenic cysts. The study consisted of 70 DFs and 20 odontogenic cysts (radicular cyst (RC), dentigerous cyst (DC) and keratocytic odontogenic tumor (KCOT) located at posterior mandibular region. Histological findings of inflammation for all specimen and mucous cell prosoplasia, squamous metaplasia, glandular epithelium for all DFs were stained with hematoxyline and eosin, periodic acid schiff, alcian blue, and mucin.

Progressive swelling and radiopaque mass in maxillary sinus: formation of stone.

Although radiopaque lesions located in the maxillary sinus are rare, differential diagnosis should include a number of pathologies. Formation of stone, namely "antrolith" in the paranasal sinuses is a very rare phenomenon and it should be considered in the differential diagnosis, as it is usually located in the maxillary sinus. In this article, we present a 47-year-old male case with unilateral chronic sinusitis for a long time and calcification in maxillary sinus in the light of clinical/radiographic findings of the lesion and treatment strategy.

Conservative management of keratocystic odontogenic tumors of jaws.

Purpose: The aim of this study was to evaluate different surgical treatment methods for keratocystic odontogenic tumors (KCOTs) and the outcome of those treatments over a 9-year period.

Patients And Methods: A retrospective review was performed on 43 KCOTs in 39 patients. In radiographic evaluations for diagnosis, follow ups and before and after treatment, panoramic, 3D CT and MR images were used.

The effect of bovine bone graft with or without platelet-rich plasma on maxillary sinus floor augmentation.

Purpose: The purpose of this study was to compare Unilab Surgibone (USB) (Mississauga, Ontario, Canada), a bone xenograft (bovine), with platelet-rich plasma (PRP) and USB without PRP to augment the human maxillary sinus in preparation to receive dental implants.

Patients And Methods: Patients who had bilateral pneumatized maxillary sinuses were included. Sinuses on one side were augmented with the USB-PRP combination and formed the study group, whereas the opposite-side sinuses were augmented with USB alone and served as controls.

Long-term provisional anterior tooth replacement using fiber-reinforced composite and avulsed tooth crowns as pontics.

The loss of anterior teeth due to trauma requires immediate attention for function and esthetics. While implant- supported or conventional fixed prostheses may be the treatments of choice for adults, relatively noninvasive and reversible provisional procedures for tooth replacement are necessary for adolescents. In recent years, developments in fiber and composite technology offer a conservative treatment approach to restore the anterior edentulous space as a fixed provisional tooth replacement.

Synovial apoptosis in temporomandibular joint disc displacement without reduction.

Objective: Our hypothesis is that increased apoptosis in synovium might contribute to temporomandibular joint (TMJ) degeneration. To investigate this, we measured soluble Fas (sFas) and nuclear matrix protein (NMP) levels in TMJ synovial fluid from patients with disc displacement without reduction as indicators of apoptosis in the synovium.

Patients And Methods: Synovial fluid was obtained from 17 joints in 17 patients (11 female, 6 male; mean age, 31.

Correction of malocclusion by anterolateral osteotomy in a traumatized maxilla.

Injuries to the face may cause long-term defects both aesthetic and functional consequences when the treatment is delayed, inadequate or absent. The varieties of osteotomy techniques are applied to improve posttraumatic malposition of the maxillofacial bones and occlusal function. In this article, a 21-year-old female involved in a traffic accident presented a severe deformity in maxilla and treated by anterolateral osteotomy is presented.

Determination of potential cellular proliferation in the odontogenic epithelia of the dental follicle of the asymptomatic impacted third molars.

Purpose: The aim of this study is to determine the proliferative potentials of dental follicles (DF) of radiographically asymptomatic impacted third molar teeth by using Ki-67 and mini-chromosome maintenance protein 2 (MCM-2) proliferation markers, and to discuss whether there is any necessity for the removal of all impacted third molars by detecting the potential of the developing cysts and tumors of its DF.

Materials And Methods: This study involved 59 DF of 54 patients referred for clinically and radiographically asymptomatic lower impacted third molars. Thirteen healthy gingiva tissues obtained during the impacted third molar operation in 13 patients served as a control group.

Ectopic dental implants in the maxillary sinus.

Migration or displacement of dental implants into the anatomical sites is a possible but rare complication. This article describes 2 cases of ectopic dental implants in the maxillary sinus, 1 of which was displaced at the time of surgery and the other which migrated 8 years after placement.

Clinical investigation of traumatic injuries in Yeditepe University, Turkey during the last 3 years.

The aim of this study was to evaluate etiology, types of traumatic dental injuries, treatment and to determine the incidence of complications according to dental injuries in patients who referred to Yeditepe University, Faculty of Dentistry, Istanbul, Turkey. The study was based on the clinical data of the 161 traumatized teeth in 92 patients. WHO classification slightly modified by Andreasen & Andreasen for dental trauma was used.

Hypohidrotic ectodermal dysplasia with bilateral impacted teeth at the coronoid process: a case rehabilitated with mini dental implants.

Bilateral migration of teeth into the coronoid process in a patient with ectodermal dysplasia has not been reported in the literature except one report in which severe hypodontia and bilaterally ectopic impacted teeth in the coronoid processes of a nonsyndromic patient occurred. This article presents a 15-year-old female with hypohidrotic ectodermal dysplasia who had surgical removal of bilaterally impacted teeth in the coronoid process and was rehabilitated with a dental implant-retained fixed prosthesis in the mandible and over-denture in the maxilla.
