Anomalous dental morphology and root resorption during orthodontic treatment: a pilot study.

The present study investigated the relation between anomalous dental morphology and root resorption during orthodontic treatment. One hundred and eleven sets of orthodontic records (a total of 1,630 teeth) were examined. Root resorption was determined from post-treatment panoramic radiographs using a five-grade quantitative measurement. It was found that patients with short or blunt roots before treatment underwent significant root shortening during orthodontic treatment. Patients with any one dental anomaly had a significantly higher degree of root resorption compared with patients with no dental anomaly. Invaginated teeth, teeth with thin or pipette-shaped roots and teeth with short or blunt roots were likely to be more susceptible to root resorption than those without such anomalies. Possible linkages between the aetiological factors of dental anomalies and the susceptibility to root resorption were discussed. The presence of anomalous dental morphology should be taken into account in orthodontic treatment planning.

[The interesting case. 6-year follow-up of a patient with atypical root length of various teeth].

Six-year observations of a female patient (13 years of age at treatment beginning) in whom the roots of certain teeth were extremely short (the causes of which being unknown) revealed no changes in the degree of resorption and so further root resorptions. The growth of the roots of these teeth (which had not fully developed at treatment beginning) progressed without disturbances. The author is of opinion that these atypical root lengths are sequelae of a temporary disturbance of the process of growth, the causes of which are unknown.

Evaluation of efficacy of Sofscale. A clinical and SEM study.

Efficacy of Sofscale in the case of removal of calculus from the root surface as claimed by manufacturers was evaluated in the present study. 32 patients suffering from chronic periodontitis, having calculus deposits in the lower incisors were selected for the study. A double blind study was conducted to evaluate the ease with which calculus could be removed. In the second part of study, a SEM study of the root surface subjected to root planing alone and root planing after application of Sofscale was done to see whether any remnants of calculus was left behind. In the double blind study conducted on 32 patients, it was found in 21 patients, calculus could be removed with greater ease and less time in experimental area compared to the control. 17 patients were able to correctly identify the product side as easier to Sofscale. Patients did not complain of increased sensitivity of teeth or discomfort following application of Sofscale. Under SEM the root surface after root planing showed the presence of smear layer whereas after Sofscale application root surface appeared devoid of smear layer. No other significant difference were noticed between the root surfaces.

Orthodontic treatment for an adolescent with a history of acute lymphoblastic leukemia.

This case report describes the treatment of a Class I malocclusion that involved ectopic position of the maxillary permanent left canine and the mandibular permanent right second molar. The patient was an adolescent who presented with a medical history that was remarkable for diagnosis and treatment of acute lymphoblastic leukemia (ALL). Dental history was remarkable for significant, generalized shortened roots that were more severe in the mandibular arch. The treatment included fixed appliance therapy in the maxillary arch only and surgical luxation of the mandibular second molar. Successful integration of the maxillary permanent left canine was accomplished without excessive flaring of the maxillary permanent incisors or disruption of the buccal segment occlusion. The risk of external root resorption on teeth with abnormal root morphology, as a result of fixed appliance therapy, should be weighed against the relative benefits that are expected from treatment.

[The dynamics of pH, free calcium and total proteins in root plaque fluid and their relationships to the cariogenic potential].

OBJECTIVE: To enhance knowledge of root caries by analysis of the dynamics of dental plaque fluids on root surface and their relationships with the caries history. METHODS: The pH, free calcium and total proteins of dental plaque fluids on sound root surfaces were analyzed before and after the sucrose challenge. Subjects were either root caries-free (RCF) or caries-positive (RCP). RESULTS: After a sucrose challenge, the pH of plaque fluids dropped significantly and the concentration of free calcium increased significantly. There were no statistical differences in pH (RCF group 6.24 +/- 0.74, RCP group 5.96 +/- 0.70) and free calcium [RCF group (0.60 +/- 0.46) mmol/L, RCP group (0.89 +/- 0.54) mmol/L] between RCF and RCP group before sucrose challenge. Following sucrose exposure, pH (5.14 +/- 0.19) and free calcium [(1.73 +/- 0.74) mmol/L] in RCP group were significantly lower than RCP group [(pH 5.28 +/- 0.16), free calcium (2.73 +/- 1.25) mmol/L]. No interrelationship has been found between the amount of total proteins and free calcium. Components (contents, change trend) in root plaque were strongly related to that in coronal plaque. CONCLUSIONS: The process of root caries may be consistent to coronal caries regarding to the acid production of bacteria after a sucrose challenge. Plaque compositions show a stronger cariogenic potential in RCP group.

[Dento-alveolar injuries].

Most dento-alveolar traumas can be managed by the dentist-general practitioner. Still, there are some specific injuries which should be treated by dental specialists. Some specific guidelines are given for the combined surgical-orthodontic treatment of fracture of the coronal part of the root, intrusive luxation, abnormal position of the permanent tooth due to traumatic displacement of the deciduous tooth, ankylosis and tooth loss.

The application of digital radiography and radiodensitometry in evaluation of chronic fibrous periapical changes of endodontically untreated teeth.

Lesions in hard tissues of teeth can be detected on radiograms only when there exists considerable decrease in mineralisation. By means of digital radiography the diagnostics of dental pathologies becomes more precise and objective. The aim of the paper was the radiodensitometric evaluation of chronic fibrous periapical changes. The material comprised 308 digital intraoral radiograms of teeth with periapical changes among which there were chosen the cases of clinically confirmed chronic fibrous periapical inflammations of endodontically untreated teeth. All radiograms were analysed in the Digora Soredex digital radiography system in gray scale, in full colour and using the tomosynthesis function. The linear measurements of root densities were carried out at the distance of 1 mm from radiological apices while the measurements of alveolar bone at the distance of 2 mm from it. Twenty-five teeth without evident periapical changes formed the control group. There were found significantly lower densities of roots and alveolar bone in the group of chronic fibrous periapical lesions in comparison with the control group. A characteristic feature of chronic fibrous periapical changes is the density of the root of an affected tooth that is higher than in acute inflammation and at the same time lower than in the control group. The radiodensitometry proved to be useful in evaluation of chronic fibrous periapical changes.

Clinical significance of non-surgical periodontal therapy: an evidence-based perspective of scaling and root planing.

Analysis of Egyptian hieroglyphics and medical papyri indicate that non-surgical periodontal treatment was common 3000-4000 years ago. Even today, scaling and root planing (SRP) remains an essential part of successful periodontal therapy. The collective evidence from numerous clinical trials reveals a consistency of clinical response in the treatment of chronic periodontitis by SRP using manual, sonic, or ultrasonic instrumentation. Thus, SRP remains the 'gold standard' to which more recently developed therapeutic modalities must be compared. Inherent to the clinical evaluation of SRP are such concerns as manual versus sonic and ultrasonic instrumentation, control of sub-gingival bacterial populations, removal of calculus, root smoothness and changes in various clinical parameters, e.g. probing depth, attachment levels, bleeding on probing and gingival inflammation. Lastly, an abbreviated discussion is presented on a relatively new paradigm of complete mouth 'disinfection' in a compressed time-frame that includes SRP as a significant component of the treatment regimen.

A clinician's 3-year experience with perioscopy.

A medical endoscope has been modified for assisting the clinician in subgingival scaling and root planing. The dental endoscope provides real-time indirect visualization of the root surface for aiding the removal of root deposits and biofilm. When the majority of biofilm and visible calculus is removed from the root surface in a periodontal pocket, the pocket will most often close, resulting in a shallow sulcus. Many lesions on single-rooted teeth can be treated successfully with this technique, resulting in a significant reduction in probable pocket depth and a gain in the calibrated attachment level. Other sites, such as furcations and maxillary first bicuspids, may demonstrate significant improvement but not complete resolution of these parameters. Perioscopy is scaling and root planing aided by indirect vision with an endoscope. This technique can offer many patients an alternative to periodontal surgery in carefully selected sites. This article describes the clinical rationale for perioscopy, defines those sites that most predictably will respond to this mode of therapy, and offers some guidelines on integrating this technology into the dental practice. The observations and recommendations in this article are based on the author's 3-year experience with the dental endoscope in his periodontal practice, the experience of other periodontists and dental hygienists, and published reports.
