Analysis of Tooth Extraction Causes and Patterns

PURPOSE: The purpose of this study was to investigate the causes and patterns of extraction of permanent teeth in the targeted population. METHODS: The study was conducted for a period of 11 months. An especially designed form was used to record the causes for extraction of a permanent tooth. Further, it was analyzed for age, gender, education, occupation, smoking, tooth position, endodontic treatment, chewing, esthetics, needs replacement, type of existing prosthesis, and causes for extraction. The various causes which were considered to determine association with the tooth extraction were dental caries, periodontal problems, trauma, orthodontics, prosthodontic failures, endodontic failures, and others. RESULTS: The percentage of extractions was almost the same in males and females aged. Maximum extractions were noticed in 36–45 years of age group (32.5%). The presence of caries was observed to be the main reason for extraction (68.1%), followed by periodontal problems (17.6%) and orthodontic problems (4.8%). The most frequently extracted posterior teeth were first mandibular molar (22.2%), followed by the third maxillary molar (15.2%). CONCLUSION: Dental caries was found to be the most common reason for the extraction of teeth. Molar teeth were found to be the most frequently extracted, with an increased number of extracted first premolars as a result of orthodontic treatment. Maxillary teeth are extracted more than mandibular, mainly due to caries and periodontal problems

Evaluation of Antibacterial Activity of Pine Tar on Periodontal Pathogenic Bacteria: An In Vitro Study

BACKGROUND: Periodontal pathogens play an important role in etiology and pathogenesis of periodontitis. Microbiological examination of sub gingival plaque is used at the present time in etiological research as well as in clinical treatment of periodontitis to select the appropriate antibiotic agent if indicated. Pine tar has been used for the treatment of various skin diseases. So the study was done to evaluate the effect of Pine Tar oil on bacteria isolated from periodontitis patients.METHODS: Plaque samples from volunteer patients were collected using sterile paper points. Robertson's Cooked Meat (RCM) medium was used for the transportation and cultivation of aerobic, microaerophilic, and anaerobic microorganisms.RESULTS: The result suggests the use of Pine tar oil for topical application in periodontal diseases. Disc diffusion analysis was sufficient enough to illustrate that 75 μl tar oil solution produced growth inhibition of microbial strains.CONCLUSION: Pine tar oil has become one of the important areas of research both in pharmaceutical and periodontal research, hence in vivo studies has to be carried out with various form of pine tar.&nbsp

Periodontal Treatment Practice and Referral Profile of General Dentists – A Cross-sectional Questionnaire Survey

BACKGROUND: Because of medical advancement, the mean age of the general population is increasing gradually. This increase in the mean age of patients has led to its implications on oral health. Hence, it is logical to assume an increase in the figure of referrals to specialists and the complexity of treatments provided. AIM: The aim of the survey was to assess the current status of periodontal treatment provided, awareness of referral profile, and criteria taken into consideration for the referral to the periodontist by general dentists. MATERIALS AND METHODS: This cross-sectional questionnaire study was conducted among 318 general dentists. The relevant work related to the status of periodontal procedures provided by dentists and their referral relationships were studied. The questionnaire consisting of six questions was designed. Descriptive statistics, including frequency distributions and measures of central tendency and Chi-square test, were used. RESULTS: The study showed that majority of the general dentists do non-surgical procedures by their own. However, around 85% of respondents did not provide surgical periodontal treatment by themselves. About 25% of the responding general dentists thought that they had inadequate education and experience in the field of periodontics which was a major reason for the referral to specialists. CONCLUSION: It was concluded that the general dentists are comfortable in carrying out the non-surgical procedures, but they had some reservations about the periodontal surgical procedures. Inadequate experience and facilities were the major reasons for the referral to periodontists. More of this type of study should be conducted to know the basic level of periodontal practices carried out among the general dentists and about the referral to the specialists

An Assessment of Dentist’s Attitudes to the Shortened Dental Arch Concept

AIM: The rehabilitation of a complete dental arch is a traditional concept to maintain proper functional occlusion, but it is neither compulsory nor always attainable in many patients. Nevertheless, it is always important to provide a minimum number of teeth for efficient function. This study aimed to assess the dentist’s attitude to a shortened dental arch (SDA) concept and to assess their perception and application of it in their clinical practice in the Aseer region, Saudi Arabia. DESIGN OF STUDY: A questionnaire with 17 questions was used to reveal the views of 204 dentists from the area of study about SDA. The questionnaire set basically consists of two parts. The first part included the dentists’ demographic data, and the second one consisted of the questions regarding the SDA concept. STATISTICAL ANALYSIS: Descriptive analysis and associations with the factors were tested for significance using Chi-square tests, and p < 0.05 was considered statistically significant. RESULTS: Among the respondents, 43.7% were aware of the SDA concept. Thus, the expected awareness about the SDA concept among the dentists was in the range of 36.31–51.05 with 95% confidence. A highly significant difference in awareness of SDA was observed between graduates and postgraduates. Among the respondents having more than 10 years of experience, the awareness level of SDA was 66.0%. CONCLUSIONS: The majority of participants alleged that the SDA concept is useful in clinical practice and is a useful treatment modality for older adults with limitations preventing complex restorative care. However, the application of the SDA varied significantly among dentists

Effectiveness of Different Chemotherapeutic Agents for Decontamination of Infected Dental Implant Surface: A Systematic Review

Aim: To evaluate the most effective chemotherapeutic agent for decontamination of infected dental implants. Material and methods: A systematic electronic literature search in MEDLINE (PubMed) and Google scholar between January 2010 to December 2021 was carried out by using the PRISMA guidelines. A total of five studies related to chemical decontamination of the dental implant were evaluated. The search strategy was based on the PICOS framework. Randomized controlled trials (RCT’s) and cohort studies evaluating the effectiveness of different chemotherapeutic agents for the decontamination of dental implants were included in the study. The outcome variable examined was the most effective chemotherapeutic agent(s) for dental implant surface decontamination after comparing the chemotherapeutic agents used in the qualifying studies. Result: Out of the basic database of 1564 records, 1380 articles were excluded due to irrelevance, unavailability, and repetition. Furthermore, 134 articles were excluded from 184 studies for various reasons. After further filtration, 13 studies were shortlisted. Two investigators (SSA and SA) appraised the quality of the selected studies using the risk of bias assessment tool. After excluding eight studies, five articles were finally included in the present systematic review. Conclusion: The data reported for the efficacy of chemotherapeutic agents in cleaning contaminated titanium surfaces are scarce, thus it is not possible to draw a definite conclusion. However, chlorhexidine (CHX) (0.2%, 0.12%), citric acid (40%) and sodium hypochlorite (1%) are the most commonly used chemotherapeutic agents; amongst them, citric acid showed the highest potential for biofilm removal from the contaminated implant surface. All three agents [CHX (0.2%, 0.12%), citric acid (40%), and sodium hypochlorite (1%)] can be recommended as therapeutic agents along with their curbs

Dental calculus – An emerging bio resource for past SARS CoV2 detection, studying its evolution and relationship with oral microflora

The most grievous threat to human health has been witnessed worldwide with the recent outbreak of Corona virus disease 2019 (COVID-19). There is mounting evidence available regarding theconnect of COVID −19 and oral cavity, particularly periodontal disease. The current review provides an update on the diagnostic potential of dental calculus and how this bio resource may help in providing us huge amount of diagnostic regarding the causative virus. Contemporary standard method of diagnosis via nasopharyngeal swabs (NPS) is tedious, may enhance the risk of aerosol contamination by inducing sneezing and detects the presence of active infection only.However,dental calculus being a mineralized deposit serves as a reservoir for biomoleculesand provides detection of past SARS CoV2 infection. Further, the abundance of information that can be obtained from this remarkable mineralized deposit on teeth regarding the viral genome, its evolution and interactions with the oral microflora shall enhance the understanding of the viral disease process and its connection with the periodontal disease. Additional diagnostic information, which may be obtained from this simple bio reservoir can complement the contemporary diagnostic strategies adopted in the management of COVID-19pandemic and enhance our existing knowledge for developing improvised novel approaches to mitigate the effects of mutated variants of the infectious agent

Validation of Digital Impressions’ Accuracy Obtained Using Intraoral and Extraoral Scanners: A Systematic Review

Background: At present, the evidence regarding digital impressions’ accuracy recorded by using digital scanners is lacking. This systematic review aimed to evaluate whether the type of scanning (intraoral/extraoral) affects the Accuracy of Digital Impressions. Method: Two independent reviewers performed a systematic search in the database both electronically and manually (PubMed, Ebsco HOST, the Cochrane Library, and Google Scholar) for articles published from 1 January 2010 to 1 December 2022. This study was registered with the International Prospective Register of Systematic Reviews (PROSPERO CRD42020188765) and followed the PRISMA statement. The question in focus was as follows: Does the type of scanning (intraoral or extraoral) affect the accuracy of digital impression? Results: A total of 449 papers were obtained by searching electronically and manually. In total, 15 complete-text papers qualified for assessment based on eligibility criteria. After reading the full-text articles, five studies were excluded. Ten studies were selected for the qualitative analysis. The qualitative data reported that the accuracy of both types of scanners (intraoral and extraoral) lies within the range of clinical acceptability. Nevertheless, the intraoral scanners seem to be more accurate when compared to the extraoral scanners for a partial arch situation. Conclusions: Scanning type affects the accuracy of the digital impression. Various factors influence the scanning ability. Intraoral scanners seem to be more accurate compared to extraoral scanners for a partial arch situation. More studies comparing the accuracy of the intraoral scanner and extraoral scanner for a complete arch scan and in an in vivo study setting are needed

Convalescing Mandibular Anterior Crowding through Piezocision and the Micro-Osteoperforation Surgical Procedure—A Clinical Comparative Study

Background: Minimally invasive periodontic (perio) surgical procedures, piezocision, and micro-osteoperforation are useful techniques for accelerating tooth movement. These techniques also offer advantages in the orthodontic (ortho) and aesthetic domains. This study aimed to evaluate and compare the rates of lower anterior decrowding with piezocision and micro-osteoperforation. Methods: This clinical study included 24 patients requiring fixed orthodontic treatments. Two periodontic techniques (piezocision (PZ) and micro-osteoperforation (MOP)) were considered for the orthodontic treatments. Each patient was randomly allocated to either the piezocision (PZ) group or the micro-osteoperforation (MOP) group. The piezocision group received five radiographically guided incisions on the labial surface of the alveolar bone, whereas the micro-osteoperforation group received one to three MOPs each using a mini-implant drill between the six lower anterior teeth, and later, an initial arch wire was ligated to each bracket. Little’s irregularity index (LII) was calculated using a digital vernier caliper on study models every four weeks until decrowding was achieved. The difference in the rates of lower anterior crowding between the piezocision and micro-osteoperforation groups was analyzed to determine the statistical significance. Results: The rates of irregularity index change during decrowding were 4.38 ± 0.61 in the piezocision group and 3.82 ± 0.47 in the micro-osteoperforation group. Piezocision was found to be 1.2 times faster than micro-osteoperforation in terms of the rate of decrowding. Conclusion: The advanced perio–ortho combination technique was advantageous in accelerated decrowding. In comparison to MOP, there was an increase in the rate of decrowding with PZ. Decrowding can be completed quickly with PZ, and it can thus be used to treat crowding effectively in a limited time frame

Effectiveness of a Single Chair Side Application of NovaMin® [Calcium Sodium Phosphosilicate] in the Treatment of Dentine Hypersensitivity following Ultrasonic Scaling—A Randomized Controlled Trial

Dentinal hypersensitivity or cervical dentinal sensitivity is one of the commonest clinical problems. The aim of this randomized controlled trial was to evaluate the effectiveness of a single chair side application of 100% pure calcium sodium phosphosilicate (NovaMin®) in reducing dentin hypersensitivity following ultrasonic scaling as evaluated on a visual analogue scale (VAS). The study included 50 subjects who were selected based on an evaluation of dentinal hypersensitivity on a VAS carried out using a metered air blast from a three-way syringe and divided into two groups (n = 25/group); i.e., the test group (Group A) received the NovaMin® paste and the control group (Group B) received a placebo paste made from pumice. All the 50 subjects included in the study were had VAS scores of 3 or more. The NovaMin® powder mixed with distilled water was applied. Dentinal hypersensitivity was reassessed immediately and after 1, 2 and 4 weeks after the procedure. Results showed that the percentage reduction of dentinal hypersensitivity following a single application of NovaMin® in powder form was about 76.38% immediately, 67.72% one week postoperatively, 52.76% two weeks postoperatively and 26.78% four weeks postoperatively. It can be concluded from the results of the current clinical study demonstrated that a single chair side application of NovaMin® in powder form has a significant and immediate reduction in dentinal hypersensitivity, which lasted nearly for four weeks
