A rare occurrence of bilateral C-shaped roots in mandibular first and second premolars diagnosed with the aid of spiral computed tomography
2014
The C-shaped canal system is an anatomical variation mostly seen in mandibular second molars, although it can also occur in maxillary and other mandibular molars. Such variation in the root canal anatomy is uncommon in mandibular first premolars and very rare in mandibular second premolars. The C-shaped canal is so named for the cross-sectional morphology of the root and root canal. The main anatomic feature of C-shaped canals is the presence of a fin or web connecting the individual root canals. Failure of the Hertwig’s epithelial root sheath to fuse on the lingual or buccal root surface is the main cause of C-shaped roots, which always contain a C-shaped canal. This case report describes …
Six-month healing success rates after endodontic treatment using the novel GentleWave System: the pure prospective multi-center clinical study
2015
Background This prospective multi-center (PURE) clinical study evaluated healing rates for molars after root canal treatment employing the GentleWave® System (Sonendo, Inc., Laguna Hills, CA). Material and Methods Eighty-nine patients met the inclusion criteria and consented for this clinical study after referral for a root canal treatment. All enrolled patients were treated with the GentleWave System. Five endodontists performed the clinical procedures and follow-up evaluations. Pre-operative, intra-operative, and post-operative data were collected from the consented patients. Each patient was evaluated for clinical signs and symptoms. Two trained, blinded, and independent evaluators score…
Assessment of non-carious root surface defects in areas of gingival recession: A descriptive study.
2015
BACKGROUND The purpose of this descriptive study was to observe the distribution of four different classes of non-carious cervical root surface discrepancies in teeth with gingival recession. Additionally to explore the different treatment modalities in the literature for each of these defects. MATERIAL AND METHODS A total of 150 subjects with at least one labial gingival recession were included in the study. 1400 teeth were evaluated using 2.5 X magnification loupes and UNC -15 probe for the presence of the cemento-enamel junction and step like defects according to Pini-Prato's classification: A-, identifiable CEJ without defect; A+, identifiable CEJ with defect; B-, unidentifiable CEJ wit…
Prenatal effects by exposing to amoxicillin on dental enamel in Wistar rats
2012
Amoxicillin is an antibiotic widely prescribed; its most frequent side effects are gastrointestinal disorders and hypersensitivity reactions. Over the last 10 years studies have been published which suggest that amoxicillin may cause dental alterations similar to dental fluorosis. Never the less, the results are not conclusive, this is why it was planned the need to make controlled studies on test animals. Objectives: The purpose of this study was to determine the effect produced by amoxicillin prenatal administration on dental enamel in Wistar rats. Study Design: 12 pregnant adult rats were used distributed into five different groups: witness control (n=2) didn't get any treatment; negativ…
The Frequency of taurodontism in the Turkish population
2011
Objectives: The aim of this study was to assess the prevalence and degree of taurodontism in a group of Turkish adult dental patients. Study design: A retrospective study was performed using panoramic radiography of 490 patients ranging in age from 18 to 65. These patients were analyzed for taurodontism. Descriptive characteristics of sex, jaws, and localization were recorded. The data was analyzed using the Pearson chi-square test. Results: Taurodontism was detected in 22.8% of patients and 4.2% of the teeth examined. Anomalies were found in 22.2% of females compared with 23.8% of males. However, no significant difference was found between the genders (p > 0.05). Taurodontism was more dist…
Durability of solvent-free one-step self-etch adhesive under simulated intrapulpal pressure
2015
Background: There are different solvents presented in simplified adhesives. Bond-1 SF has been developed, which contains neither water nor organic solvents, in order to eliminate technical issues in terms of evaporation of solvents and concerns for the durability of resin-dentin bond. Thus this study was conducted to evaluate the microtensile bond strength (μTBS) of solvent-free and ethanol-based one-step self-etch adhesives to dentin under simulated intrapulpal pressure (IPP). Material and Methods: Occlusal surfaces of human molars were prepared to expose mid-dentin depth. Bond-1SF Solvent-Free SE [SF] and Adper TM easy one [AE] adhesives were applied on dentin specimens. Resin composite b…
Influence of two different surgical techniques on the difficulty of impacted lower third molar extraction and their post-operative complications
2015
Background : Post-operative complications of various degrees of severity are commonly observed in third molar impaction surgery. For this reason, a surgical procedure that decreases the trauma of bone and soft tissues should be a priority for surgeons. In the present study, we compare the efficacy and the post-operative complications of patients to whom two different surgical techniques were applied for impacted lower third molar extraction. Material and Methods : Patients of the first group underwent the classical bur technique, while patients of the second group underwent another technique, in which an elevator was placed on the buccal surface of the impacted molar in order to luxate the …
Evaluation of a porous hydroxyapatite alloplast in the management of grade II furcation defects in molars: a case series
2012
Introduction: The present case series evaluates the efficacy of a hydroxyapatite graft material in the management of grade II furcation involvement in first molars. Material and methods: Eight patients presenting with a total of 9 grade II furcation defects in relation to the facial aspect of either maxillary or mandibular first molars were treated with a porous hydroxyapatite alloplast. The clinical outcomes were measured in terms of change in probing pocket depth and clinical attachment level (vertical and horizontal) at 6 months post-operatively. Radiographs were used as supplements. Results: At 6 months, there was a mean pocket depth reduction of 3.12±1.25 mm, a mean vertical attachment…
Establishing a diagnostic tool for assessing optimal treatment timing in Indian children with developing malocclusions
2011
Objective: To interrelate chronological age, cervical vertebrae maturational stage and dental calcification stages and to establish latter as first level diagnostic tool to estimate timing of pubertal growth spurt. Materials and Methods: Sample derived from pretreatment panaromic and lateral cephalometric radiographs of patients 8-14 years old. Study sample divided into three groups depending upon Angle’s molar relation: Group I, Group II, Group III. According to chronological age, into: Group A: 8-11 years Group B:11-14 years, further separating males and female subjects in each group. Demirjian et al method was used to assess dental maturity and for skeletal maturity the New Improved Vers…
The effect of cigarette smoking on the severity of pain, swelling and trismus after the surgical extraction of impacted mandibular third molar.
2012
Objective: The study objective was to investigate the effect of cigarette smoking on the severity of pain, swelling and trismus on male after the surgical removal of impacted lower third molar. Material and Methods: This prospective comparative study was conducted for 150 male in two groups of patients, smokers and non-smokers. Each group consisted of 75 patients; smoking patient were the ones who smoke more than twenty cigarettes per day for more than one year of continuous smoking. Postoperative pain was evaluated using a visual analog scale (VAS) and the degree of swelling was evaluated through facial reference points’ variation. The presence of trismus was analyzed through measurement o…
