Successful root canal treatment depends on having comprehensive information regarding the root(s)/canal(s) anatomy. Dentists may have some complication in treatment of third molars because the difficulty in their access, their aberrant occlusal anatomy and different patterns of eruption. The aim of this review was to review and address the number of roots and root canals in third molars, prevalence of confluent canals in third molars, C-shaped canals, dilaceration and fusion in third molars, autotransplantation of third molars and endodontic treatment strategies for third molars.

Objectives: To report the results at year three of an evaluation of fixed-fixed all-ceramic bridges, constructed in a yttria oxide stabilized tetragonal zirconium oxide polycrystal (Y-TZP) substructure, placed in adult patients in UK general dental practices and luted using a self-adhesive resin-based cement. Methods: Ethical approval was obtained. Four UK general dental practitioners were asked to recruit patients in accordance with the trial protocol. After obtaining informed written consent, appropriate vitality and radiographic assessments were completed and the pre-operative status of the gingival tissues noted. The teeth were prepared and bridges constructed in accordance with the manufacturer's instructions. Each bridge was reviewed annually within 3 months of the anniversary of its placement by a calibrated examiner, together with the clinician who had placed the restoration. The examiners evaluated the integrity of the restoration, its anatomic form, marginal adaptation, surface quality, sensitivity, the condition of the adjacent gingivae, and the presence or absence of secondary caries. Results: A total of 34 bridges were examined at the three-year review. All Y-TZP frameworks were intact and no bridge retainers had debonded. Two veneering ceramic chips, in total, were detected over the three-year period of observation: the patients in whom this had occurred were unconcerned. A further abutment tooth had been successfully endodontically treated, through an occlusal access cavity, in addition to the two already reported at year one. Significance: At year three, the 34 Lava Y-TZP fixed-fixed bridges, placed in patients attending UK general dental practices, were found to be performing satisfactorily. © 2011 Academy of Dental Materials.

Patient's perceptions of risk from bloodborne viruses (BBVs) and variant Creutzfeldt-Jacob Disease (vCJD) in relation to attendance at dental practice is understudied. This survey of an opportunistic sample of 50 dental practice patients examined patients' perceptions of the risk of acquiring BBVs and vCJD following dental treatment. Major concerns of patients revolved around hand hygiene practices rather than risks from BBVs or vCJD. No patient had avoided or delayed a visit to the dentist because of concerns over risks of cross infection. Copyright © 2014 Published by Elsevier Inc.

The aim of this study was to retrospectively assess the frequency and type of lower bonded retainer failures and to analyze the possible influence of operator experience.The records of 1062 patients with lower bonded retainers were analyzed with respect to retainer type and failure, timing of failure and differences among operators.34.9% of all patients experienced retainer failure. Cuspid retainers with two bonding sites failed significantly less often than multiple teeth retainers with six bonding sites. One or more bonding sites became detached in 22.8% of the patients, 17.9% had at least one total retainer loss, while only 0.8% of the patients suffered from retainer fractures. Experienced orthodontists exhibited significantly fewer failures than postgraduate students.The present cohort presented a relatively high failure rate of 34.9%. Lower bonded cuspid retainers failed somewhat less often than 3-3 retainers. In addition less operator experience was likely to correlate with a higher failure rate.

Epidemiological data suggest an association between respiratory diseases and periodontal health. However, the link between the overall dental status and single lung function measures, within a practical clinical context, is not well studied.Following a prospective cross-sectional design, consecutive adult patients were evaluated. Next to spirometry, anthropometric data, profession, smoking status, symptoms, self-rated exercise performance, comorbidities, allergies and medication were determined. Assessment of dental status comprised carious lesions, dental fillings, missing teeth, dentures, insufficient fillings/dentures, implants, oral mucosa diseases, calculus, decayed-missed-filling-teeth (DMF-T)-index, periodontal screening-index, and orthopantomograms.Among 587 adult patients considered, 206 were included (119 female; median age 42.0 years; 56% smoking history). Most patients had dental fillings (86.9%), fix/mobile dentures (66.5%), missing teeth (56.8%) and calculus (84.0%), the overall DMF-T being 15 (9; 21). Periodontitis was present in 53.9%, an abnormal orthopanthomogram in 47.9% of subjects. Regarding spirometric indices expressed as % predicted, dentures, missing teeth, oral mucosal diseases and a DMF-T>15 (median) were associated with lower maximal expiratory flows at 25% of vital capacity (MEF25) (p<0.05 each). In adjusted logistic regression analyses, only dentures were associated with low MEF25% predicted and with the ratio of forced expiratory volume in 1s to forced vital capacity (FEV1/FVC; p<0.05 each). However, periodontitis and DMF-T were linked to age (p<0.001) and packyears (p<0.05) only.Within a real-life clinical setting, only the presence of dentures showed weak associations with lung function, suggesting small airways dysfunction and obstruction. Most of the associations were explained by smoking habits and age.

Local anaesthesia is used routinely throughout dentistry. Complications are, however, relatively uncommon. A unique case of superficial skin necrosis and neurological symptoms following administration of local anaesthesia for dental treatment is reported and the possible mechanisms behind this unusual presentation are discussed. Awareness of this possible complication and its mechanism helps clinicians diagnose and manage patients with similar problems appropriately.
