Laser use in endodontic for increase the adhesion of root canal filling a synchrotron radiation micro tomography study
No full textThe aim of the present paper is to explore, through a high-resolution synchrotron radiation-based micro
computed tomography experiment, the efficiency of the Er:YAG laser involvement in the debridement of the
root canal of pathologic teeth, applied after the chemo-mechanical treatment of the canal. The adhesion
quality of root canal filling is the consequence of the root canal cleaning and shaping, thus preventing the
leakage. Twelve extracted single-rooted teeth were considered. The first 5 mm of the roots, corresponding to
the apical region of the teeth, were initially investigated through high-resolution synchrotron radiation phasecontrast
micro computed tomography. Afterwards, a chemo-mechanical endodontic treatment was performed
and the same region of the teeth was imaged again. Finally, an Er:YAG laser with PIPS tip treatment was
applied on the same teeth and a last tomographic scan was done. The chemo-mechanical treatment properly
removed the necrotic tissue only in the upper part of the apical area of root canal, but tissue debris were found
in the lower and partially also in the medium and upper part of the apical region, especially when the apical
area exhibited a larger curvature. The laser treatment applied afterwards gave good results in terms of removing
the debris from the apical area of root canal, mainly when they remained in the main canal. The present study
proves the capability of Er:YAG with PIPS tips laser treatment to enhance the removing of tissue debris from
the apical region of root canals after a chemo-mechanical treatment. The high-resolution synchrotron radiationbased
phase contrast micro computed tomography is the most powerful tool for a non-destructive 3D
investigation method of the root canal morphology analysis and a proper characterization technique for the
assessment of the endodontic treatment
Unconventional Non-Invasive Diagnostic Techniques and Treatment of White Spot Lesions in Paediatric Dentistry and Orthodontics
No full textMinimal Intervention Dentistry (MID), a concept that aims to minimize the interventional procedures applied on teeth affected by dental caries, emphasizes the importance of prevention and detection of lesions in early stage. The white spot lesion (WSL) is the first visible stage of the carious process, affecting the enamel. Their detection and treatment has been significantly improved in the last decade through new technology available. Our paper describes a non-invasive detection method, using a lighttransmission device (transillumination of the teeth using Diagnocam, by Kavo) , combined with a resin infiltration technique (using Icon, by DMG) of the WSL
Clinical Evaluation Of The Periodontal Condition During Fixed Orthodontic Treatment
No full textThroughout orthodontic treatment, oral hygiene is particularly important and must be rigorously controlled throughout therapeutic act. The aim of our clinical study was to examine the periodontal status of patients before, during and after orthodontic appliances are used. 50 patients were selected, plaque index, gingival index, modified papillae bleeding index and clinical probing depth was evaluated on anchorage teeth, separately those with orthodontic bands and tubes. One of the most common findings during this kind of treatment is gingival alteration in the posterior region. Our practical observations showed a different status of these alterations at patients wearing bands on the anchorage teeth versus those with buccal tubes. Using some of the indices which describes the periodontal status at adult and adolescent patients, we found out that adolescents present a higher plaque index, and the accumulation of dental plaque is more severe when bands are used in both categories. Another finding, which is very important in everyday practice is that gingival inflammation and plaque accumulation decrease one month after debonding
Crown-Root Angulation of Central Incisors in Cases With Maxillary Lateral Incisors Agenesis
No full textDental agenesis of the maxillary lateral incisor is a frequently seen anomaly in children and teenagers nowadays. It can alter the esthetics as well as the functions in the frontal area of the maxilla and therefore, early detection and therapy would be beneficial. The treatment often implies an interdisciplinary approach between orthodontics and implantology. One of the particularities of this kind of treatment is given by the distal angulation of central incisor’s root, which invades the space required by the dental implant. Any treatment plan should begin with a thorough radiographical analysis of the space and morphological particularities of the central incisors
The Evaluation of the Apperception Regarding the Pain Related Emotional Status of Children with Dental Maxillary Abnormalities
No full textAbstractThe evaluation of psychological factors concerning the interaction between children and dentists involves a great importance, therefore we proposed to assess the dental pain experience and anxiety in children with orthodontic problems. A number of 110 children aged 6-11 years answered a 10 items questionnaire. 35.5% of the patients reported earlier unpleasant dental experiences. Girls showed fear 2.46 times higher than boys. Children's age correlated to dental fear, specific maneuvers, and estimated levels of fear. 74.54% of the patients considered the orthodontic treatment is necessary. We concluded that child- patients must be approached according to their complex personality
Original Research. Evaluation of Dental Erosion in a Group of Romanian Children Diagnosed with Gastroesophageal Reflux Disease
No full textAbstract
Gastroesophageal reflux disease (GERD) is a very common digestive disorder, which occurs when the acidic contents of the stomach returns into the esophagus to some extent, reaching the mouth, thereby increasing the frequency of dental erosion and caries. Since saliva plays a huge role in oral homeostasis, it is important to examine the role of this parameter in the appearance of the above mentioned oral lesions. The aim of our study was evaluate the oral condition of children suffering from reflux disease and to assess the relationship between salivary pH and the incidence of dental erosion and caries. In this prospective study we examined 25 children diagnosed with GERD, referred for hospitalization. Bedside intra-oral examination (DMFT index, gingival index) and strip method pH value determination was performed. We observed that patients with low pH values had increased caries frequency, and dental erosion was also noticeable. Statistical significance was determined comparing the DMFT index in groups with different pH values. We concluded that the high number of erosions is closely related to gastroesophageal reflux disease, as a consequence of the low pH value, which represents the main cause of oral manifestations in GERD.</jats:p
