Introduction: The present study was undertaken to evaluate the anatomy of the maxillary sinus in relation to its position and the height of its septa, using cone beam computed tomography (CBCT).

Materials and methods: In this descriptive retrospective study, 300 CBCT images of maxillary sinuses of patients with posterior maxillary edentulism were evaluated. The maxillary sinus septa were evaluated in relation to their prevalence, height, and position; t-test and Mann–Whitney tests were used for the analysis of data.

Results: Sinus septa were detected in 44% of the subjects, with equal frequencies in the anterior, middle, and posterior positions. The mean height of the septa was 3.6 ± 1.56 mm.

Conclusion: In a population of Iranian subjects, in half of the cases, the sinus septa might be present in the anterior, middle, and posterior positions.

Clinical significance: In order to avoid intraoperative problems during sinus lift procedures, it is necessary to accurately evaluate the sinus, preferably with the use of CBCT.

Keywords: Cone beam computed tomography, Dental implant, Maxillary sinus septa.

Introduction: To verify the influence of age on factors associated with peri-implant bone loss after prosthetic rehabilitation over osseointegrated implants.

Materials and methods: This is an analytical, observational, and longitudinal study with initial 23 participants. Patients presenting with osseointegrated implants with their respective prostheses installed were included, and they could be carriers of chronic and degenerative diseases, such as diabetes, osteoporosis, hypothyroidism, cardiovascular disease (CVD), and systemic arterial hypertension. Thus, 18 participants with 57 implants were selected and followed up from 2009 to 2013. For statistical analysis, chi-square or Fisher’s exact test was used for the association of systemic conditions and bone loss. Student’s t-test was used for mean comparisons of age and number of total upper and lower implants.

Results: The average The average age of the sample studied was 71.05 years (65–80). The average implant per person was 3.2. Smoking had an influence on both mesial and distal bone loss, and the latter was significant (p = 0.0370). The association between bone loss and gender was also si    gnificant (p < 0.05). Moreover, male gender and upper implants were factors significantly associated with bone loss. The systemic conditions, when isolated, did not have significant influence on implant survival.

Conclusion: Age is not a factor that, alone, contraindicates implant-rehabilitating therapy. On the contrary, smoking has a significant influence on dental implant survival. Systemic diseases, such as osteoporosis, hypothyroidism, diabetes, hypertension, and heart diseases, when controlled, are not contraindication factors.

Clinical significance: This study is relevant for assessing peri-implant bone loss in elderly patients, right after implant installation and over time. Therefore, it was possible to verify that age is not a limiting factor for this procedure. Controlled systemic diseases do not contraindicate implant installation, but smoking is a factor that affects implant survival.

Keywords: Aging, Case–control study, Chronic disease, Dental implants, Implants, Prostheses, Risk factors.

Aim: Dentists are probably contributing to the development of bacterial resistance to certain antibiotics. Campaigns to promote prudent use of antibiotics in dentistry are, thus, needed but require proper identification of dentists’ knowledge gaps. The objective here was to comprehensively evaluate antibiotic prescription knowledge of dentists in Saudi Arabia.

Material and methods: A link to an online, previously validated questionnaire was emailed to 5199 dentists registered with the Saudi Dental Society. The questionnaire comprised 42 scorable items measuring antibiotics prescription knowledge in five different domains in addition to nonscorable questions regarding first-choice antibiotics and previous attendance of a course/workshop about antibiotic prescription. Each correct answer was given one mark. Mean scores were calculated as percentages and categorized as good (> 80%), intermediate (60-80%), or poor (< 60%).

Results: The response rate was 9.4%; however, only 373 (7.2%) fully completed the questionnaire. Around half of the participants (52%) reported prescribing amoxicillin/clavulanate as the firstchoice antibiotic; 62% reported attending a course/workshop in the last 5 years. The average knowledge score was 69%, being highest for nonclinical indications (79%) and lowest for prophylactic use (56%). The worst per-item scores were noted for rheumatic heart disease (19%), trismus (28%), surgical extraction (30%), apicectomy (31%), and periodontal abscess (33%). Female dentists, dentists in governmental sector, and those with higher qualifications had significantly better knowledge.

Conclusion: The level of knowledge was hardly intermediate and several deficits were identified, indicating an urgent need for educational campaigns and provision of guidelines promoting rational use of antibiotics by dentists.

Clinical Significance: Irrational use of antibiotics by dentists can contribute to the problem of antibacterial resistance.

Keywords: Antibiotic resistance, Antimicrobial agents, Dentistry, Drug prescription, Knowledge.

Glass-ionomer cements (GICs) are mainstream restorative materials that are bioactive and have a wide range of uses, such as lining, bonding, sealing, luting or restoring a tooth. Although the major characteristics of GICs for the wider applications in dentistry are adhesion to tooth structure, fluoride releasing capacity and tooth-colored restorations, the sensitivity to moisture, inherent opacity, long-term wear and strength are not as adequate as desired. They have undergone remarkable changes in their composition, such as the addition of metallic ions or resin components to their composition, which contributed to improve their physical properties and diversified their use as a restorative material of great clinical applicability. The lightcured polymer reinforced materials appear to have substantial benefits, while retaining the advantages of fluoride release and adhesion. Further research should be directed towards improving the properties, such as strength and esthetics without altering its inherent qualities, such as adhesion and fluoride releasing capabilities.

Keywords: Adhesion, Dentin bonding, Fluoride release, Glassionomers, Resin-modified glass-ionomers, Restoration.

Aim: The aim of this study was to evaluate the effect of intermixing brands of addition silicone impression materials on the dimensional accuracy of stone models using two-step putty-wash technique.

Materials and methods: Two common brands of addition silicone impression material (Express and Aquasil) were used in this study. A total of 40 impressions of a stainless steel model simulating a three-unit bridge were made, 10 impressions for each group. Accuracy was assessed by measuring two dimensions (inter-abutment and intra-abutment) on stone models obtained from impressions of the stainless steel model. Each sample was measured thrice and the mean value was calculated. The data were analyzed using analysis of variance (ANOVA) and Scheffe’s post hoc test.

Results: The results indicated that each of the inter-abutment and intra-abutment dimensions of the stone models was significantly higher than those for the stainless steel model (p < 0.001). However, there was no statistically significant difference in each of the inter-abutment and intra-abutment dimensions of the stone models among the four tested groups (p < 0.05).

Conclusion: The results obtained were statistically analyzed and the values of the inter-abutment and intra-abutment dimensions were all within the clinically acceptable range.

Clinical significance: Intermixing brands of additional silicone impression materials evaluated in this study did not affect the dimensional accuracy of obtained stone casts. This will help to minimize the wastage of materials due to lack of either light or putty consistency of the same brand of additional silicone impression material.

Keywords: Dimensional accuracy, Impression materials, Putty-wash.

Introduction: Various types of oral hygiene measures have been practiced by different populations around the world, as there is difference in the oral hygiene products including toothpicks and toothpowders. Miswak or tooth cleaning stick, for mechanical tooth cleaning, can be traced back at least to pre-Islamic times. Currently, many of the world populations still use chewing sticks as the single method for tooth brushing. The present study was done to study the incidence and prevalence of caries among Miswak and non-Miswak users.

Materials and methods: The study was done consisting of 120 cases and 120 control group (60 boys and 60 girls in each group) from the secondary school. The materials used were light, explorer, mirror, gloves, upper and lower teeth models, Miswak, and common toothbrush.
After the recording of the primary data, Miswak was given to case group and the students were trained to use it on the teeth models.
After 2 years, the examination of the teeth was done using the same method as before start of the study and by the same investigators. All the data were recorded, tabulated, and analyzed with the help of Statistical Package for the Social Sciences (SPSS) statistics version 17 using Student’s t-test.

Results: From the 240 participants, only 211 had continued the study for the total period of time. Out of these, 111 were from the study group and 100 from the control group. On comparison of the decayed-missing-filled (DMF) index scores of the study and control groups, before and after completion of the study, had also shown that the caries index was increased and the difference was found to be statistically significant.

Conclusion: From the study, it can be concluded that the study group using Miswak had less number of caries incidence than the control group of non-Miswak.

Clinical significance: Miswak can be used as teeth cleaning aid in day-to-day life as it can reduce the caries incidence.

Keywords: Caries prevalence, Miswak, Non-Miswak, Toothbrushing.

Objectives: Oil pulling is an age-old practice that has gained modern popularity in promoting oral and systemic health. The scientific verification for this practice is insufficient. Thus, this study evaluated the effect of coconut oil pulling on the count of Streptococcus mutans in saliva and to compare its efficacy with that of Chlorhexidine mouthwash: in vivo. The null hypothesis was that coconut oil pulling has no effect on the bacterial count in saliva.

Materials and methods: A randomized controlled study was planned and 60 subjects were selected. The subjects were divided into three groups, Group A: Study Group: Oil pulling, Group B: Study Group: Chlorhexidine, and Group C: Control Group: Distilled water. Group A subjects rinsed mouth with 10 ml of coconut oil for 10 minutes. Group B subjects rinsed mouth with 5 ml Chlorhexidine mouthwash for 1 minute and Group C with 5 ml distilled water for 1 minute in the morning before brushing. Saliva samples were collected and cultured on 1st day and after 2 weeks from all subjects. Colonies were counted to compare the efficacy of coconut oil and Chlorhexidine with distilled water.

Results: Statistically significant reduction in S. mutans count was seen in both the coconut oil pulling and Chlorhexidine group.

Conclusion: Oil pulling can be explored as a safe and effective alternative to Chlorhexidine.

Clinical significance: Edible oil-pulling therapy is natural, safe and has no side effects. Hence, it can be considered as a preventive therapy at home to maintain oral hygiene.

Keywords: Chlorhexidine, Coconut oil, Streptococcus mutans.

Molar incisor hypomineralization (MIH) is a developmental defect affecting teeth. High prevalence rates of MIH and its clinical implications are significant for both the patients and clinicians. A wide variation in defect prevalence (2.4-40.2%) is reported. It seems to differ with regions and various birth cohorts. Some of the recent prevalence studies are tabulated.
Patient implications include hypersensitive teeth, rapid progression of caries, mastication impairment due to rapid attrition, and esthetic repercussions. Implications for clinicians include complexity in treatment planning and treatment implementation, poor prognosis of the restorations, difficulty in achieving pain control during treatment, and behavior management problems. Intention of this paper is to review the etio-pathogenesis, prevalence, clinical features, diagnostic features, and eventually present a sequential treatment approach, i.e., in accordance with current clinical practice guidelines.

Keywords: Dental enamel hypoplasia, Incisor pathology, Molar incisor hypomineralization, Molar pathology.

Objectives: The purpose of this in vitro study is to compare the compressive strength (CS) and diametral tensile strength (DTS) of the zirconia-reinforced restorative material (Zirconomer®) with conventional glass ionomers (Fuji 1X) and amalgam.

Materials and methods: Specimens (n = 120) were fabricated from silver amalgam, reinforced glass ionomer cement (GIC) (glass ionomer, Fuji 1X GC Corp.), and zirconia-reinforced glass ionomer (Zirconomer, Shofu Inc.) for testing the CS and DTS. The results were analyzed using analysis of variance, followed by a Tukey post hoc test.

Results: Both CS and DTS were found to be significantly higher for the zirconia-reinforced GIC and silver amalgam compared with GIC (p < 0.001).

Conclusion: A newer class of restorative material like Zirconomer helps to overcome the potential hazard of mercury, but retains the strength and durability of amalgam as well as the sustained high-fluoride release of GICs. Furthermore, long-term studies are required to confirm its use as an alternative to the currently available posterior restorative material.
