Evaluation of the effects of cotton roll-biting on debonding pain: a split-mouth study

Introduction: Debonding pain is an unpleasant sensation that is frequently encountered during debonding procedure. Aim of the study: To investigate the effectiveness of cotton roll-biting on pain caused by the debonding procedure. Materials and methods: 102 patients (61 females, 41 males) who were at the debonding stage in orthodontic treatment were included in the research. The study was planned using a split-mouth design: one side of the jaw was the study, and the other side was the control. The anxiety level of participants was measured before debonding. On the study side, debonding was performed while patients were biting a cotton roll. On the control side, debonding was implemented as a routine debonding procedure. Study and control sides were assigned differently in each successive patient. The debonding pain of each tooth was recorded using the Visual Analog Scale prepared separately for each tooth. Shapiro–Wilk and Mann–Whitney U tests were used for statistical analysis. For both gender groups, patients were sequenced according to the average amount of pain per tooth. Subsequently, statistical analysis was repeated by using 50% of patients suffering more pain. Results: In the lower second premolar tooth, a statistically significant difference was detected. Pain scores were statistically higher in the study side for this tooth. No statistically significant differences were found for all other teeth. Conclusions: Cotton roll-biting has no alleviating effect on debonding pain. When debonding is performed gently using a squeezing action without applying torsional forces, additional pain relief methods are not required.

Behavior of Children during Dental Care with Rubber Dam Isolation: A Randomized Controlled Study

Background: The establishment of the dental dam improves dentist working conditions and patient protection. The purpose of this study was to analyze the behavior of the child during dental care with or without a dam. Methods: In this interventional randomized study, 51 patients are divided into two groups, one with a rubber dam and the other with cotton roll isolation. Their behavior was observed during the treatment of temporary molars. The duration of the treatment, the patient’s feeling with a visual analogue scale (VAS), the behavior (B) of the child measured with a hetero-evaluation scale (modified Venham scale) and the cardiac frequency (CF) were measured. Results: The group treated with a rubber dam has a significant decrease in the various stress parameters that have been identified (B, p value = 0.034; CF, p value = 0.015). Subgroups of patients with and without nitrous oxide sedation were compared and similar results were obtained. Conclusions: Isolation with a rubber dam reduces child’s stress during dental care. Although it is slightly more time-consuming and training is necessary for a quick and effective placement, it allows dentists to perform dental care in the best possible conditions, while reducing dental anxiety in young patients.

Comparison of Fissure Sealant Chair Time and Patients’ Preference Using Three Different Isolation Techniques

This randomized clinical trial aimed to evaluate the patient’s preference and chair time needed during pit and fissure sealant placement under three isolation techniques (Isolite system, rubber dam isolation, and cotton roll isolation). Participants, aged 6–15 years and requiring four sealants on the first or second permanent molars, attending the pediatric dental clinics at King Saud University in Saudi Arabia were enrolled according to the inclusion criteria. Each participant received sealants on three random first or second permanent molars using three isolation techniques. The time required for sealant placement was recorded for each technique. Following sealant placement, an interview-based questionnaire was administered to the participants to evaluate their preference regarding the isolation techniques. Forty-eight children (23 male and 25 female) with a mean age of 8.58 ± 1.93 years participated in this study. The mean chair times were 248.14, 255.89, and 243.29 s for the Isolite system, rubber dam isolation, and cotton roll isolation, respectively. Approximately 79% of participants considered cotton roll isolation to be the most comfortable, whereas approximately 71% were significantly less likely to use rubber dam isolation again. In conclusion, there were no significant differences in sealant placement time among the three isolation techniques. However, cotton roll isolation was the technique that was most preferred by the participants.

The Correlation between Caries and Quality of Life of Mentally Disabled Learners

Introduction. Mentally disabled learners have dental problems 30% more complex than the ordinary toddler. It is because they have intellectual function disorder and adaptive behavior. This condition caused limitations in cleaning teeth optimally. So it will increase the risk of caries. This study objective is to find the correlation between the quality of life and dental caries at mentally disabled learners. Method. An analytical observational study with a cross-sectional approach to 118 learners in Sidoarjo, Indonesia, by total sampling. The variables in this study were quality of life (was measured with WHOQL-BREF index) and dental caries (was measured with DMF-T index). Tools and materials used are dental kids, alcohol 70%, cotton pellet, cotton roll, tampon, and WHOQL-BREF sheet. The data were presented descriptively in the form of a frequency distribution table, continued by Spearman Correlation test to analyze the correlation between the quality of life and dental caries at mentally disabled learners. Results. Most of the respondents are male (61%), with a range of age is 16-20 years old. The average quality of life for mentally disabled learners is the moderate category ( 65%). The average dental caries is considered as high. Spearman correlation shows p≤α(0,05) means there is a correlation between dental caries and quality of life. Conclusion. There is a correlation between dental caries and the quality of life for mentally disabled learners.

Effectiveness of methods for cleaning arch wire: an in vitro study

The aim of this study was to evaluate various methods of removing bacterial and fungus biofilm, to simulate orthodontic arch wires cleaning before reinsertion in the patients appliance. Rectangular Nickel Titanium (NiTi), Stainless Steel (SS) and Titanium Molybdenum (TMA) wires were divided into five groups, then contaminated with strains of Streptococcus mutans and Candida albicas. Four segments of each group served as control and were not contaminated. Six cleanings methods were used to remove the biofilm: cotton roll and a chemical agent (chlorhexidine, sodium hypochlorite, 70% alcohol), cotton roll and water, steel woll and immersion on enzymatic detergent. There was a control group not decontaminated Then wires were placed in broth separately, and after an incubation period the optical density (OD) was measured, observing whether there was microbial growth. A wire segment of each subgroup of SS 3M® was taken to the Scanning Electron Microscope (SEM) for visualization of the treatment response. The results were submitted to one-way ANOVA test and Tukey post-test. With the exception of 70% alcohol, the disinfection means behaved similarly regardless the type of wire. Two percent Chlorhexidine and 1% Sodium Hypochlorite totally removed the microorganisms while other agents left a high microbial concentration. Chemical cleaning is necessary to remove biofilm in orthodontic wires; 1% Sodium Hypochlorite and 2% Chlorhexidine are good disinfectants for this purpose.

Influence of Isolation Methods on Retention of Pit and Fissure Sealants in Young Permanent Teeth based on Simonsen’s Criteria: A Randomised Clinical Trial

Introduction: Pit and Fissure Sealants (PFS) are chemically-active liquid materials that are introduced into the occlusal surface of caries-susceptible teeth. These form a micro mechanically bonded, protective layer preventing access to caries-producing bacteria, from rest of the oral environment. Aim: To evaluate the retention of PFS placed on young permanent teeth using two isolation methods. Materials and Methods: This clinical study was carried out in the Department of Paediatric and Preventive Dentistry, at Narayana Dental College and Hospital, Nellore, Andhra Pradesh, India. One hundred Permanent First Molars (PFM) from 25 healthy, cooperative children in the age group of 6-9 years were assigned by block randomisation into two groups (isolation type); each group containing the upper and lower PFMs of the right and left side receiving two different treatment modalities (split-mouth design). In Group I (n=50 teeth), the teeth received sealant with rubber dam isolation, and in Group II (n=50 teeth), with cotton roll isolation. The sealant was applied to all the PFMs as indicated. All the teeth were evaluated using Simonsen’s criteria at regular intervals of 3, 6, and 12 months. The data collected were subjected to statistical analysis using the SPSS statistical package (version 17) and statistical significance was set at 0.05. The difference in the retention of PFS with the two isolation methods was analysed using the Chi-square test. Results: After 12 months, the marginal integrity rate for sealants placed with a rubber dam and cotton roll isolation were 75% and 64%, respectively. The results were better in Group I than in Group II, although there were no statistically significant differences with respect to marginal integrity, discolouration, and anatomical failure. Conclusion: Retention of PFS in young permanent teeth was better with rubber dam than cotton rolls for isolation, though the results were not statistically significant.

Effectiveness of Modified Traps for Protection Against Fruit Flies on Mango

Mango is one of the primary fruit export commodities in Indonesia. The productivity of mango can be increased by controlling the pest population, including fruit flies Bactrocera spp. Various efforts to control the population of fruit flies have been carried out, either by implementing traditional methods or by using synthetic pesticides. However, synthetic pesticides can cause pollution, and therefore we need to control the fruit flies’ population by using the most effective fruit fly trap mode. The study was conducted in the mango yield (monoculture) of Department of Agriculture in Majalengka. The traps in this study were modified Steiner traps with funnels, modified Steiner traps without funnels, bottle traps with funnels, bottle traps without funnels, and modified gypsy moth traps. Each trap was fed with 0.2 ml of Methyl eugenol dripped on a cotton roll and hung in the trap. The results showed that the number of fruit flies caught in each trap every week is significantly different. The highest number of fruit flies caught in each trap every week was achieved by bottle traps without funnels that caught 135 flies, while the lowest number of fruit flies caught was recorded by the gypsy moth traps with 16 flies. The transparent color of the bottles and a large number of holes effectively lured the fruit flies into the bottle traps without funnels.
