ABSTRACT
Ectopic presence of teeth is a rare clinical event. Ectopic maxillary third molar in maxillary antrum may be confused with sino-nasal disease. Dentigerous cyst associated with an ectopic maxillary third molar is a very rare finding
ABSTRACT
The main objectives of root canal therapy are cleaning, shaping and obturating the canal system in three dimensions and preventing reinfection. So the irrigation is important part of a root canal treatment as it allows for cleaning beyond the reach of root canal instruments. Inadequate irrigation or instrumentation without irrigation increases the accumulation of debris on the cutting surfaces of instruments as well as debris and smear layer on root canal walls. In this review article, comparison of MTAD [mixture of tetracycline citric acid and detergent] and sodium hypochlorite [NaOCl] as irrigating material in endodontics is made
ABSTRACT
Background: Dental plaque may cause oral problems that may include dental caries, periodontal problems, and halitosis. Motivation, awareness and manual dexterity have much effect on tooth brushing. The advantages related with manual and battery operated tooth brushing have been reported different in the literature
Objective: To compare the manual and battery operated tooth brush for plaque removal efficiency
Study Design: Randomized control trial
Setting: The Dental OPD of Department of Community Dentistry, Liaquat University of Medical and Health Sciences, Jamshoro
Period: November 2011 to June 2013
Methods: Total 100 patients of both genders, aged ?18 years were included. Patients were equally divided into manual and battery operated brush groups. The presence of plaque was checked and plaque index was recorded. Wilcoxon sign pair test was applied to compare pre and post plaque score for manual and battery operated tooth brush. Independent sample t test was applied to compare percent reduction of plaque score between groups. The significance level of P-value was up to 0.05
Results: In manual brush group, 27 were male and 23 were female. Mean age was 25.65 +/- 5.87 years. In battery operated brush group, 32 were male, 18 were female. Mean age was 29.92 +/- 10.37 years. Before manual brushing mean plaque score was 1.88 +/- 0.65 while after brushing it was reduced to 1.11 +/- 0.43. Percent reduction was 40.96%, p=0.0005. Mean plaque score was 1.35 +/- 0.37 and 0.69 +/- 0.29 before and after brushing respectively in battery operated brushing. Percent reduction was 48.9%, p=0.0005. Battery operated brushing was significantly more effective than manual [p=0.023]
Conclusion: Battery operated tooth brush was significantly more effective than manual toothbrush. It removes significantly more supragingival plaque than manual tooth brush
ABSTRACT
The purpose of this study was to analyze the incidence of post-obturation flare-ups in teeth following single visit versus multiple visits in Root Canal Treatment. Two hundred patients were assigned for single-visit versus multiple visits root canal treatment. For each tooth treated, the clinical factors and conditions existing before and after the completion of treatment were recorded. This data included patient's age, gender, type of tooth, pre-operative status of pulp and periapical tissues and recording pain and swelling [flare-ups] postoperatively after 1 day,1 week and 1 month. Statistics analyzed by chi-square test, SPSS 19. Fifteen out of two hundreds cases showed flare-ups after treated single visit versus multiple visits appointments. All patients in this study suffered irrereversible pulpitis 200 patients divided into two equal groups. Group1 Patients were obturated in single visit while group 2 patients were obturated in multiple visits appointments. It was observed that out of total 15[7.5%] cases of flare-up, 6[40%] were visited multiple time and 9[60%] were visited single time. It was concluded that the incidence of flare-up or post obturation pain is related to the number of visits and clinical experience of the dentist
ABSTRACT
For successful endodontic outcome, accurate working length has to be determined. Even with improved systems of working length [WL] measurement, different readings may be recorded in different electrolytes present in the canal
Methodology: total 90 patients were selected for this prospective in vivo study resented at Department of Operative Dentistry, Liaquat University of Medical and Health Sciences, Jamshoro, during 6 months i.e. from 1[st] Sep 2014 to 28[th] Feb 2015, with single rooted permanent mandibular first premolars with matured apices. After extirpated pulp tissue a file was inserted in the canal and WL was obtained by radiograph as well as by electronic apex locator [EAL]. The measurements determined by both methods were compared by applying paired sample t-test. SPSS 18 was used for data analysis
Results: among 90 subjects 37 were males. Mean +/- SD WL obtained radiographically was 19.8 +/- 1.03-m whereas mean +/- SD WL obtained electronically was 18.9 +/- 1.05 mm. Mean difference between measurements of both methods was 0.87-mm, which was statistically significant [P <0.05]
Conclusion: the electronic apex locator was better than the radiograph in determining working length of root canal at statistically significant level
