Maturogenesis of immature non-vital permanent tooth: A case report
Get PDFPulp necrosis in an immature permanent tooth leads to incomplete root end closure, thin fragile root dentine walls, and unfavorable crown-root ratio making routine endodontic therapy difficult. Mineral trioxide aggregate (MTA) apexifi cation procedure may beused as first-line treatment when root length or width is acceptable and risk of root fracture is not anticipated. Among the existing treatment approaches, maturogenesis is the biological approach that utilizes the full potential of pulp for dentin deposition. In the present case report, tooth #8 was managed with MTA apical plug and tooth #9 with maturogenesis using platelet-rich fi brin as scaff old. Clinical follow-up for 3, 6, 9 months has shown resolution of clinical symptoms and radiographic examination showed closure of the apex, increase in the thickness of root dentine and increased percentageof radiographic root area as measured using image J software on periapical radiographs
Class II correction using twin block appliance: A case report
No full textAim of this study was to see the eff ect of twin block effect in permanent dentition phase.Twin block from its inception and evolution of the appliance itself has been widely accepted as a more competent Class II corrector compared to earlier bulky monobloc appliances. The eff ect of the twin block functional appliances is mostly dentoalveolarhaving a small skeletal eff ect. Functional appliances can be used successfully used in growing patient with certain Class II malocclusion. It is dependent on patient’s compliance. It also simplifies the fixed appliance phase. A 14-year-old girl was treated withtwin block appliance. The design of appliance and treatment results were demonstrated in following case report. In permanent dentition, twin block produce similar eff ect as in mixed dentition phase. With proper case selection and good patient cooperation, we canobtain a significant result with twin block appliance
Root resorption: An abnormal consequence of the orthodontic treatment
No full textExternal apical root resorption is an abnormal consequence of orthodontic treatment, although it may present in the absence of orthodontic treatment. Root resorption produces root shortening and break down the integrity of teeth arch and it is very important for success of orthodontic treatment. Orthodontics is the only branch whichactually uses the infl ammatory process as a tool of solving esthetic and functional problems. Every orthodontist should know the risk factors of root resorption and they should do everything to reduce possibility of root resorption. The severity and degree of root resorption related with orthodontic treatment are multifactorial, involving environmental factors, and host factors. The literature shows that root resorption is mainly related with treatment duration, fi xed orthodontic treatment, individualsusceptibility, tooth structure, and type of orthodontic tooth movement
Evaluation of knowledge, experience and preparedness on management of medical emergencies among dental practitioners in Dar es Salaam, Tanzania
No full text Background: Some life-threatening medical emergencies do occur in dental setups. Hence, timely diagnosis and prompt management of these conditions by skilled dental practitioners can save lives of patients. Aim: To evaluate the dental practitioners' knowledge, experience and preparedness regarding medical emergencies on dental chair. Methods: Cross section descriptive survey involving 105 public and private dental practitioners in Dar es Salaam City. Pre-tested structured questionnaire gathering information pertaining to socio-demographic characteristics, experience on medical emergencies, knowledge on management of medical emergencies and preparedness for managing medical emergencies was used as a data collection tool. Results: Out of 105 participants (34, 32.4%) reported to have encountered one or more medical emergencies during the past four years. Syncope (23.8%), hypoglycemic attacks (12.4%), and post extraction bleeding (10.5%) were the most reported encountered medical emergencies by the participants. Knowledge on emergency drug kit and the confidence during using/administering the drugs and equipments was low. Medical emergencies trainings were undertaken by 15.2% respondents: However, all of them had a desire for further medical emergencies training. Conclusion: The study revealed that syncope is the commonest medical emergency event. Dental practitioners had a superficial knowledge of medical emergencies, drugs and equipments.  
Dentition Status and Treatment Need among Psychitric Patients at Ndola Central Hospital, Copperbelt Province in Zambia.
No full textAim and Objective: To determine prevalence and correlates of dentition status and treatment needs among psychiatric patients in Zambia. Methods: A total of 110 patients participated in the survey. Dentition status was assessed according to WHO 1987 oral health survey method. Independent correlates for DMFT were established using multivariate logistic regression analysis. Results: Most of the patients were aged less than 35 years (61.8%) and had attained secondary or higher level of education (66.4%). None of the females smoked or consumed alcohol. Meanwhile 45.0% of males smoked and 26, 4% consumed alcohol. Overall, 66.4% of patients had DMFT (one or more). Only age was independently associated with DMFT. Patients aged <35 years were 1.60 (95% CI [1.03, 2.49]) times more likely to have DMFT compared to those aged 35 years. Majority (82.7%) of patients needed dentition treatment. Extraction (40%) was the most required treatment followed by prosthesis (36.5%). Conclusion: Poor dentition status was prevalent in our study population with extensive unmet needs for dental treatment
Effect of three resin cements on micro push-out bond strength of fiber-reinforced composite post to radicular dentin at different root levels
Get PDFAims & Objectives: To assess the micro push-out bond strength of fiber-reinforced composite (FRC) post to root dentin at different levels after cementation with an etch-and-rinse, self-etch and a self-adhesive type of resin cement. Methods: Thirty extracted human maxillary central incisors were transversely sectioned at 15 mm from the apex. Canals were prepared with rotary instruments to obtain an apical size of 45, 0.02 taper and obturated. Standardized post spaces were prepared and specimens were randomly divided into three groups according to the cement used for post cementation: Variolink II (etch-and-rinse resin cement), Panavia F 2.0 (self-etch resin cement) and RelyX Unicem 2 (self-adhesive resin cement). The roots were sectioned into 1 mm thick slices at the coronal, middle and apical level and subjected to micro push-out test in a universal testing machine at a crosshead speed of 0.05 mm/minute. Failure mode was evaluated for each specimen under a stereomicroscope at 10X magnification. Two–way analysis of variance (ANOVA) and Tukey B multiple comparison test were used to analyze the data with the significance level set at p<0.05. Results: The micro push-out bond strengths were significantly higher for Variolink II compared to the other two types of cements (p<0.05). Bond strength decreased significantly from the coronal to the apical region of the root canal irrespective of the luting cement used. Conclusion: This study showed that the type of resin cement and the region of the root canal dentin does have an effect on the micro push-out bond strength of fiber-reinforced posts
Juvenile fibrosarcoma mimicking a gingival mass: A rarity encountered
No full textFibrosarcoma is a malignant neoplasm of fi broblasts that seldom aff ects the oral cavity. It usually manifests as an innocuous, sessile, lobulated, painless and non-hemorrhagic submucosal mass with normal coloration. Juvenile fi brosarcoma is a rare entity that has a much better prognosis compared with the adult type. The aim of this article is to present a case of juvenile fi brosarcoma in a 9-year-old girl, which was thought to be benign on clinical examination and to document the rarity of fi brosarcomas in the jaws of children
Evaluation of cervical dysfunction in patients with myofascial pain dysfunction syndrome: A prospective study
No full textObjectives: The presence of signs and symptoms of craniocervical dysfunction are increasingly recognized in patients with temporomandibular disorders. This study aims to establish the role of cervical dysfunction in myofascial pain. Methods: A total of 20 patients of myofascial pain with cervical dysfunction and 20 patients with only myofascial pain were considered for the study (Group 1 and Group 2). Following history of tenderness of muscles of mastication, stiff ness of neck muscles, limitation of mouth opening, temporomandibular joint tenderness and assessment of Visual Analog Scale (VAS), patients were examined for muscles of mastication, maximum comfortable mouth opening, temporomandibular joint tenderness, neck muscles and cervical range of motion. Patients in - Group 1 were treated with physiotherapy to the cervical muscles and Group 2 patients were given physiotherapy to the muscles of mastication. Patients were assessed for the relief of signs and symptoms of myofascial pain post treatment and every month for 3 months. Results: Both the groups responded equally well to physiotherapy with reduction in VAS, number of tender muscles and increased maximum comfortable mouth opening post treatment and during the follow-up. Interpretation and Conclusions: Physiotherapy to the neck muscles brought about signifi cant improvement in the signs and symptoms of myofascial pain and hence cervical dysfunction could be one of the extrinsic etiologies for myofascial pain

No full text Aims: This study was aimed to localize the mandibular canal (MC) for Bangalore population, using digital orthopantomographs (OPGs). Objectives: The aim was to assess the location of the inferior MC in both sides of the mandible and in both genders and to assess the bone levels in both the genders as age increases. Materials and Methods: This study consisted of 160 OPGs, D1 = Distance between superior border of MC and root apex of 2nd molar, D2 = Distance between superior border of MC and root apex of 2nd premolar, D3 = Distance from superior border of MC to alveolar bone crest. D4 = Height of MC, D5 = Distance between MC to the lower border of mandible. Results: Right and left side comparison between males and females were not significant. Right side comparison between males and females was significant for all except D2. Left side comparison between males and females was significant for all except D1. Correlation between age and parameter in males and females showed a positive correlation with all except D3. Conclusion: The results showed all the variables were correlated linearly with the age in both genders. Significant differences between males and females measurements were detected
Surgical management of gingiva to restore aesthetics and function of the oral cavity. A Comprehensive Review
No full textImpression making for all fixed prostheses requires access to the prosthetic margin while minimally traumatizing the tissue, so that clinicians can provide as much clinical information as possible This information allows the technician to design the prosthesis to meet the criteria of the periodontium and allow the gingival tissues to recover to their original state. The procedures used to retract the gingiva are either mechanical, chemico-mechanical or surgical. The mechanical techniques may use copper bands and ring collars. Another technique uses retraction cords, providing a gingival sulcus enlargement with or without using impregnated cords with haemostatic or astringent solutions. The final technique is the gingival surgery. It may use Ingraham's diamonds that simultaneously finish the subgingival preparation margins and make superficial epithelium curettage. The second procedure is electro-surgery which provides constant results when use, thereof, is well indicated. Finally lasers can also provide another possibility for surgical retraction. The purpose of this review article is to summarize available evidence with respect to current methods of gingival retraction and to provide the clinician with practical tips
