ABSTRACT Complete denture is a gold standard therapy used in most cases of edentulous patients. But when the alveolar ridge is highly resorbed, a regular prosthetic base induces automatically a lack of stability and retention of dentures. In such challenging situations, conventional therapeutic alternative is not effective and other therapeutic solutions such as piezography and implants are preferred. This article reports a full prosthetic management of a highly resorbed mandibular alveolar ridge with the presence of a voluminous tongue, in order to improve prosthetic integration.
ABSTRACT Diagnosis of pulpal condition is very much important in the determination of most appropriate treatment for primary tooth. For proper pulpal diagnosis, thorough history, clinical and radiographic examinations should be done. Various pulpotomy procedures are there but mostly each is associated with side effects .In present scenario lasers are used most commonly and are associated with very less disadvantages. A thorough understanding of laser physics and biological effects is mandatory for any provider. Comprehensive beginner and ongoing training is imperative to use these devices effectively and safely. Present review article mainly concentrate on the detailed explanation of laser pulpotomy.
ABSTRACT The complexity of the occurrence of these oral mucosal infections highlights the need to combine an antiviral drug, in addition to the local treatment administered, in the management of oral diseases associated with viral infections. However, a careful and well-conducted clinical examination gives a good diagnostic orientation to better adapt the best therapeutic procedure. The objective of this study was to review the non-tumoral oral manifestations of viral infections through a review.
ABSTRACT All on four concept is an efficient technique to treat completly edentulous patient with high ridge resorption. using tilted distal implants we can reduce the lenght of posterior cantilever and avoid complex surgical procedures. Survival rate with this technique reach the 99.8% for the first 5 years (5).
ABSTRACT The idea to develop processes capable to produce physical components quickly and without requiring tooling, led to the development of the “free form fabrication” (FFF) or “rapid prototyping” (RP) technologies in the early 1980s. Rapid prototyping (RP) also known as additive manufacturing or three-dimensional (3D) printing is a group of evolving technologies that create 3D objects additively in a layer-by-layer manner from a predefined 3D computer model. The RP technologies have brought several advantages to the manufacturing industry in such a way that these technologies are evolving toward the production of end-use parts. This paper presents a review of rapid prototyping and manufacturing (RP&M) technologies from their origins.
ABSTRACT Background: In most cases the etiological factors of periapical diseases are oral contaminants through the root canal or degenerative pulpal tissues. Infections of the dental pulp occur as consequence of dental caries, operative dental procedures, trauma, and involve a mixed, predominantly gram-negative, anaerobic micro-organisms.Therefore the mere surgical removal of the periapical lesions without proper root canal disinfection and obturation will not result in the healing of the periapical tissues. So successful management and repair of periapical pathosis depends on complete debridement of the root canal system, followed by three-dimensional obturation to seal both the apical foramen and coronal orifice. Objectives: To find out clinical and radiological evaluation of non-surgical management of non-vital teeth with periapical pathosis by conventional root canal treatment. Methods: A total number of 50 infected teeth with periapical lesions were treated by conventional root canal treatment. This Experimental study was carried out for a period of 12 months from January 2019 to December 2019 in Shah Ali Dental Clinic, Dhaka, Bangladesh. Irritants from the root canal system was removed by mechanical instrumentation (Crown down Technique), chemical irrigation with Naocl and by using Calcium Hydroxide as intra-canal medicaments and fluid tight obturation both apically and coronally resulting repairs of inflamed periapical tissues. Depending on the extension of tissue damage repair varies from a simple reduction and resolution of the inflammation to a more complex regeneration involving remodeling of bone, periodontal membrane and cementum. Results: This study present 1 years clinical and radiological follows up period. Among 50 cases 40 cases could be treated as acceptable as their responses were good both clinically and radiologically and 7 patients came back with some complications among them 5 cases were uncertain and 2 cases were unacceptable. ..............
ABSTRACT The aim of this study was to determine how elderly people (75 years +) living in their own homes perceive their oral health and to assess their awareness of the availability of domiciliary dental services and their perceived need for such services. This quantitative study comprised 63 participants who were patients at three private dental practices in Stockholm, Sweden. The questionnaire covered oral health, oral care habits and their perceived need and knowledge of domiciliary dental care. Ninety-one per cent of the participants managed their daily oral hygiene unassisted, 63% reported good oral health and 75% reported good general health. The most common oral problems encountered in the last six months were dental calculus (68%), xerostomia (41%) and receding gums (25%). Those who used an electric toothbrush reported better oral health than those who used only a manual toothbrush (p=0.02). There was a linear correlation between self-perceived general health and oral health. Most of the participants (93%) had not previously heard about domiciliary dental services and 82% did not perceive a need for such services. Thus, the majority of the participants reported good oral health, with a correlation between perceived general health and oral health. However, there is a need to raise awareness about domiciliary dental services in independent elderly people.
ABSTRACT The main perplexing challenge in the orthodontic treatment is the long duration of the treatment. The orthodontic force applied only static force results in hyalinization. If a light vibratory force is applied along with the fixed orthodontic force, it will reduce the hyalinization phase thus enhance the tooth movement. This study aims to investigate the effect of the intraoral vibratory stimulation on the tooth movement in patients undergoing orthodontic treatment. Fixed orthodontic treatment cases in which bilateral premolar extractions are performed were selected. Split mouth study was done in these patients. Patients were provided electric tooth brushes to use daily for 15min / day. OPG’s were obtained periodically and the relevant structures were traced. Measurements were done from canine to 2nd premolar and from canine to 1st molar in all the subjects. The amount of tooth movement was calculated and compared in both experimental and control side. The manual readings show the significant difference between the rates of tooth movement by 2% in experimental group as compared to control group.
ABSTRACT Background: Saliva is an important body fluid having importance in forensic tracing, is identified by its high amylase activity compared to other biological materials using salivary staining method. Whether this activity changes with oral habits, time and temperature, material on which the stain is absorbed or collected and in other biologic materials has to be known. Methodology: Study samples comprised of fresh saliva samples of 20 subjects each, with and without habits and one sample each of blood and vaginal secretions, collected on both filter paper and cotton cloth. Amylase activity of the pre-weighed blood and vaginal secretions, salivary samples at differing temperature and time and salivary samples diluted with blood & vaginal secretions at differing concentrations were recorded. Results: Saliva samples showed high specific activity of amylase in cloth and in habituated subjects, but this activity decreased with time and temperature. Whereas blood and vaginal samples showed very less specific activity compared to saliva samples and it decreased with increasing dilutions with saliva. Conclusion: When studied in a larger scale, the study observations may help in narrowing down the findings at a crime scene which could serve as a guide line for further research in forensics.
