Second Mesiobuccal Canal

Objectives: To determine the frequency of second mesiobuccal canal (MB2) in a sample of 223 extracted maxillary permanent 1st molars. Study Design: In-vitro Cross-sectional study. Setting: Department of Endodontic at Peshawar Dental Hospital. Period: June 2019-Nov 2019. Material & Methods: The samples were processed with application of the Clearing Technique which includes demineralization with nitric acid, dehydration with ethanol and clearing with methyl salicylate. The samples were classified according to Weine’s system of root canal classification. Results: Among the 223 samples, 30% were found to have Weine’s type1 root canal in the mesiobuccal root (second mesiobuccal canal absent).  Second mesiobuccal canal was present in majority of the samples (70%) with Weines type2 (2-1) predominant with 23.32%, Weines type3 (2-2) present in 15.7% and Weines type 4 (1-2) present in 21% of the samples. 9% of the samples could not fit into Weines classification so they were placed in Vertuccis classification for root canal system type 6 (2-1-2). Conclusion: The present study concludes that the second mesiobuccal canal is more frequently found in maxillary permanent 1st molar teeth than our textbooks report, irrespective of quadrant and gender. Therefore, time should be given to evaluation of its anatomy by the clinician before starting the root canal treatment for the greater good of the community.

This cross-sectional study aimed to determine the degree of visibility of maxillary and mandibular anterior teeth at rest in different age groups and to evaluate the smile line, smile arc, and number of maxillary teeth displayed during smiling among the Saudi population visiting King Abdulaziz University Dental Hospital, Jeddah, Saudi Arabia. A total of 157 participants (77 males and 80 females) were included in this study with an age range of 19 to 69 years. All participants had maxillary and mandibular anterior teeth without restorations. Crown length and visible portions of anterior teeth at rest were measured using a Fowler Electronic Digital Caliper. Three measurements of each variable were recorded by two independent dental interns and calibrating their measurements was performed. Smile line, smile arc, and number of teeth displayed during smiling were examined. The collected data were statistically analyzed using SPSS software. It was found that the average clinical crown lengths in the maxillary lateral incisor, mandibular central incisor, and canine were significantly higher in males than females. At rest position, females displayed more maxillary central and lateral incisors. The displayed length of maxillary teeth at rest is inversely proportional to increasing age; the reverse occurs in mandibular teeth. The common visibility of maxillary teeth during smiling was from the second bicuspid to its counterpart. Average smile line and consonant smile arc were the most common characteristics. It was concluded that both age and gender affect the characteristics of tooth display at rest and in smiling. These effects should be considered during treatment planning and restoration of anterior teeth to obtain a more predictable esthetic outcome.

Root Canal Irrigants

The aim is to assess how aware the dental students are about endodontic irrigants and the deleterious effect. Successful root canal therapy relies on the combination of proper instrumentation, irrigation, and obturation of the root canal. Of these three essential steps of root canal therapy, irrigation protocol is very important as it determines the healing of the periapical tissues. The primary endodontic treatment goal must thus be to optimize root canal disinfection and to prevent reinfection. Cytotoxicity of root canal irrigants is essential due to their close contact with host tissues. The study aimed to assess how aware the dental students are about the deleterious effects of endodontic irrigants. A cross-sectional study was conducted among dental students in January 2020. The survey was made on the app survey planet and a questionnaire was administered to 100 dental students about their awareness of cytotoxicity of irrigants in endodontics. The data was collected and put into bar charts in SPSS version 20 by IBM for statistical results. It is observed 38% were interns, 33% were final years and 29% were third years. 90% were aware of what irrigants are, 86% were aware of the types of irrigants, 76% were aware of the cytotoxicity of irrigants, 49% used sodium hypochlorite, 21% used chlorhexidine, 10% used MTAD, 8% used citric acid and 12% have used all of the above. 65% are aware of the duration of irrigants in canals. 59% think irrigants can be used in a previously treated tooth, 20% disagree and 21% are not sure. A p-value of 0.000 was obtained which is statistically significant as p<0.05. In vitro cytotoxicity tests are usually carried out for new materials before applying them clinically. These irrigating solutions should be used at lower concentrations to enhance cell viability and protect the tissues from toxicity damage, irrespective of their increased efficacy at higher concentrations. Through this study, it was evident that students are not fully aware of the deleterious effects of endodontic irrigants though they are used daily. The awareness of the concentration and type of irrigant to be used should be more emphasized during theory classes so that the same can be followed during clinical procedures.

Teeth loss, especially first permanent molar teeth loss is the ultimate barometer of failure or success in dentistry and dental health programs. A cross-sectional study was conducted among 210 patients attending in outpatient department of selected dental hospitals in Dhaka city to find out the loss of first permanent molar teeth among them. Regarding age (34.8%) of the respondents were below 25 years followed by 25.5% between 25 – 35 years (mean age 33.16 ± 14.10 years). In case of educational status (31%) completed primary education followed by 16.2% were graduates and 33.3% were illiterates. Majority (59.5%) of the respondents had monthly family income below 5000 BDT (mean income 6802.39 ± 6630. 39 BDT). Among the respondents, 33.8% knew brushing technique and 79.5% of them brushed once in a day. Majority (68.5%) of them used tooth paste for brushing and tooth brush was used by 67.1% of the respondents. In case of first permanent molar tooth missing, 50% missed lower left, 19.6% lower right, 17.4% upper left and 13%  upper right. Among the respondents, 86% teeth loss was due to caries followed by periodontal disease (12.4%) and orthodontic reason (5.2%). Among the respondents who lost tooth, 55.7% were below 15 years followed by 15 - 30 years (34.3%) and above 30 years (10%). Regarding oral hygiene status, 19% had satisfactory and 81% had unsatisfactory oral hygiene. So it can be concluded that loss of permanent first molars can be avoided if good preventive measures are used before these teeth erupt and are continued after they have erupted in addition to maintaining proper oral hygiene. Further large scale study regarding this topic is recommended.Bangladesh Journal of Dental Research and Education Vol.5(2) 2015: 40-43

Place and duration of study: Department of endodontics, Sir Syed Dental College & Hospital, Karachi from1st May 2011 to 31st August 2011. Material and Methods: Of the 400 teeth from 370 individuals (age range 12-50 years) were endodonticallytreated during four months by faculty members and postgraduate residents enrolled in a specialisation programme in department ofEndodontics. All patients were examined clinically and radiographically. For each case, information was collected in specifically designedproforma including location of the affected tooth, age and gender and reasons for endodontic treatment. Results: Of the 400 treated teeth, 225(56.25%) were mandibular and 175 (43.75%) were maxillary teeth. 236 teeth (59.0%) were from females and 164 (41.0%) from males.Significant differences were found between the maxillary and mandibular arch. Molars and premolars required significantly more frequentendodontic treatment than canines and incisors as revealed in fig.1. The most frequently treated tooth was the mandibular right first molar(9.12%) followed by the mandibular left first molar (7.07%). The mandibular first molar was the most common tooth to undergo endodonticprocedure than maxillary first molar. The most frequently diagnosed pathosis was irreversible pulpitis (44%), pulp necrosis (22%), retreatmentendodontic (17%), elective RCTs (10%) traumatic exposures were (7%) as shown in fig. II. Conclusions: Irreversible pulpitis was the mostfrequent cause of root canal treatment followed by pulp necrosis. Teeth of females required more endodontic treatment than males. The mostfrequent root canals were carried out in mandibular molars than maxillary molars.

Effect Of Age

We aimed to investigate the association between blood pressure (BP) and tooth loss and the mediation effect of age. A cross-sectional study from a reference dental hospital was conducted from September 2017 to July 2020. Single measures of BP were taken via an automated sphygmomanometer device. Tooth loss was assessed through oral examination and confirmed radiographically. Severe tooth loss was defined as 10 or more teeth lost. Additional study covariates were collected via sociodemographic and medical questionnaires. A total of 10,576 patients were included. Hypertension was more prevalent in severe tooth loss patients than nonsevere tooth lost (56.1% vs. 39.3%, p < 0.001). The frequency of likely undiagnosed hypertension was 43.4%. The adjusted logistic model for sex, smoking habits and body mass index confirmed the association between continuous measures of high BP and continuous measures of tooth loss (odds ratio (OR) = 1.05, 95% CI: 1.03–1.06, p < 0.001). Age mediated 80.0% and 87.5% of the association between periodontitis with both systolic BP (p < 0.001) and diastolic BP (p < 0.001), respectively. Therefore, hypertension and tooth loss are associated, with a consistent mediation effect of age. Frequency of undiagnosed hypertension was elevated. Age, gender, active smoking, and BMI were independently associated with raised BP.
