Published: February 2022

The article highlights the relevance of energy saving problems on a global scale and the need to regulate by state laws the production and application of frequency converters, which allow to reduce the energy consumption of asynchronous motors by 30-60% depending on the load as a result of the International Energy Agency's targeted energy policy. Different characteristics of controlling the asynchronous motor, which is the main transmission of artesian well pumps, with Straight and Frequency Transducer (Variable Frequency Transmission) from the power grid are compared; the principles of energy-saving frequency converter (FC) with pulse-width modulation, increasing the power factor (PF-Power Factor) are interpreted, as well as the principle of operation and bloc explained, including the principle of operation and the block diagram. The authors report on the positive results of the work carried out in the oil fields by the Institute of Control Systems of ANAS together with Cybernetics SDB on the identification of energy-saving sources and finding ways to save energy. The article substantiates the urgency of creating a frequency converter-based monitoring, diagnostic and control system for subartesian well pumps. At the same time, the surface and underground equipment of subartesian wells is studied, technical requirements for an automated control system for early diagnosis and optimal control of their technical condition are formulated, and the structure of a new SCADA system is proposed. A comparative analysis of the operation of the artesian well engine directly and by the FC-based Artesian Well Smooth Control Station (AWSCS) proposed in the system is given for different cases.

Published: January 2022

This study evaluated the influence of resin cements and glass ionomers on tensile strength and types of failure of zirconia copings cemented on titanium base abutments. Forty-two samples were prepared, which were formed by a Cone Morse implant, a titanium abutment with the fixing screw, and a zirconia structure made using a CAD/CAM system. The samples (n = 42) were randomly distributed according to the cementing agent: resin-modified glass ionomer cement (RelyX Luting 2), self-adhesive resin cement (RelyX U200), and self-curing resin cement (Multilink N). After cementation of the copings, half of the samples from each group (n = 7) were randomly selected and subjected to thermocycling (5000 cycles). A tensile load test was performed on a universal testing machine until failure occurred (1 mm). In addition, the type of failure was analyzed using the two-way analysis of variance test and Tukey’s post-hoc test (α = 0.05). Lower tensile load was observed for the glass ionomer cement (p < 0.001) regardless of the evaluation period. After thermocycling, a significant reduction in tensile load values was verified for both evaluated cements (p = 0.047). For the resin cements, failures were predominantly of the screw fracture type (82.1%) already with the use of glass ionomer cement, and 28.5% of the failures were of an adhesive type between the zirconia coping and the cement. Resin cements have better stability under tensile load compared to resin glass ionomers when cementing zirconia copings on titanium base abutments.

Published: January 2022

The aim of this study was to compare the microshear bond strength of different resin cements to CAD/CAM-created lithium disilicate ceramics after 24 hours and after 1 year (10,000 thermocycles). Forty (40) ceramic bars were subjected to pretreatment comprising airborne abrasion with aluminum oxide particles, etching with 10% hydrofluoric acid and Monobond N application. Bars were divided into 4 groups (n = 10), based on cement type: light-cured Variolink Esthetic LC (VLC) and dual-cured Variolink N (VN) at two different times: after 24 hours and after 1 year. Silicone molds were used to prepare cement cylinders on a ceramic surface. The set was stored in distilled water at 37ºC, for 24 hours or subjected to 10,000 thermocycles. The molds were removed and microshear bond strength was tested. Data were submitted to two-way analysis of variance and Tukey’s test (α = 0.05). Based on the comparison between cement values at different aging times (p = 0.035), VN after 24 hours (27.10 ± 0.92) and after 1 year (20.62 ± 1.25) presented significantly higher values than VLC after 24 hours (14.79 ± 0.76) and after 1 year (6.61 ± 0.81). Bond strength recorded for both cements after 24 hours (VN: 27.10 ± 0.92 and VLC: 14.79 ± 0.76) was significantly higher than the one recorded after 1 year (VN: 20.62 ± 1.25 and VLC: 6.61 ± 0.81). The thermocycling reduced the values observed for both investigated cements; bond strength was greater for dual-cure resin cement than for light-cured resin cement.

Published: January 2022

In 2013, the Oriental Republic of Uruguay enacted a law regulating the cannabis market, and since then, an increasing number of users has been registered. Previous reports based on data from other countries link cannabis smokers to worse periodontal health status. The aim of this study is to describe self-reported gingival and periodontal health status and estimate the prevalence of periodontitis among Uruguayan cannabis club members. A cross-sectional study was conducted on a convenience sample of cannabis club members in Uruguay. A survey was used to gather sociodemographic data and information on oral hygiene, use of cannabis and other drugs, and self-reported gingival and periodontal health status. Eight questions validated in Spanish were used to estimate the prevalence of total periodontitis and severe periodontitis, based on two previously implemented predictive models. The survey was completed by 50 people, of whom 68% were male and 78% were in the 20-40 year age range. Based on the first model, estimated prevalence was 12% for total periodontitis and 10% for severe periodontitis. Based on the second model, estimated prevalence was 36% for total periodontitis and 12% for severe periodontitis. These findings suggest that smoking cannabis could potentially have a detrimental effect on oral health status.

Published: January 2022

The aim of this study was to compare the performance of conebeam computed tomography (CBCT), clinical and surgical probing in assessing maxillary molar furcation involvement (FI). Furcation defects (n= 120) were assessed through CBCT, clinical and intra-surgical evaluation (ISE). Furcation Involvement, vertical and horizontal bone loss were assessed through clinical probing, CBCT and probing during ISE. Three trained radiologists evaluated CBCT images and intra- and interobserver agreement were calculated by Kappa test and Intraclass Correlation Coefficient (ICC). McNemar and Wilcoxon tests were used to compare clinical probing, ISE and CBCT. Accuracy, sensitivity, specificity, positive and negative predictive values were calculated to detect FI. Clinical findings showed 28 sites with Degree I, 25 sites with Degree II, and 8 sites with Degree III. Good intra- (k=1.00) and interobserver agreement (k=0.773) were observed. Intraobserver and interobserver agreement for horizontal bone loss were moderate, k=0.485 and k=0.549, respectively. Intra-surgical findings showed Degree I at 21 sites, and Degree II and Degree III FI at fifteen sites each. Clinical evaluation showed 75% agreement with ISE and 78% with CBCT. Accuracy for clinical detection of FI was 75%, while for CBCT evaluation ranged from 72.5% to 77.5%, considering the 3 observers. Significant differences were found at distal sites using CBCT (p<0.05). Clinical evaluation and CBCT showed similar results for the presence or absence of FI. Concerning horizontal and vertical bone loss, CBCT was not considered a precise examination method for incipient bone defects.

The purpose of the study was to evaluate the prevalence of Oral Mucosal Lesions (OMLs) in an adult population from Santo Domingo, Dominican Republic. 751 subjects from eight communities from Santo Domingo accepted the invitation to participate in an oral screening from October 2016 to January 2017. 248 subjects were evaluated and clinically examined, age range 18-86 years. A validated instrument was designed to record demographic factors, age group, gender, anatomical location, presence or absence of OMLs, risk factors such as tobacco consumption and its frequency, and different forms of tobacco and alcohol use. A systematic oral clinical examination was conducted by a specialist. The presence or absence, and anatomic location of OMLs were recorded. The sample consisted of 44.4% males and 55.6 % females. 228 subjects had 1 or more lesions (91.9%), the median was 3 lesions per patient. In relation to risk factors, tobacco use in general was reported by 26.2 % of the subjects, with cigarette smoking reported by 75.4%, followed by other forms as “hookah” 9.2 %, marihuana 9.2%, cigars (“puros”)4.6% and pipe smoking 1.5%. Among the oral lesions detected by screening, the nonpathological group was prevalent, and included physiologic melanin pigmentation as the most frequent (25.0%) followed by palatal/mandibular tori (20.2%), Fordyce granules (7.9%), and Exostosis (5.6%). Potentially malignant disorders (Oral Leukoplakia, Oral Lichen Planus and Actinic Cheilitis) corresponded to 2.2%, 0.3 %, and 0.3%, respectively. No malignancy was observed clinically. This study contributes to determining the prevalence of OMLs in Dominican Republic and to identifying risk factors. This is the first study reporting the prevalence of oral mucosal lesions among the Dominican adult population. This information is vital for establishing a public health program targeting the high-risk group to improve the oral health status in this population.

This study compared the shaping ability of single-file reciprocating (WaveOne Gold) and multifile rotary (Mtwo) systems on mandibular oval-shaped canine root canals, using microcomputed tomography (micro-CT). Thirty mandibular canines were scanned by micro-CT and assigned to one of two groups (n=15) according to the system used for root canal preparation: WaveOne Gold or Mtwo. After preparation, the teeth were rescanned, and the percentage of untouched canal area, apical transportation and centering ability were analyzed. The data was evaluated using Kruskal and Mann- Whitney tests (p<0.05). No difference was found in percentage of unprepared canal area between groups in the entire root canal or the apical third, or in centering ability (p>0.05). WaveOne gold had less canal transportation than MTwo at the 5 mm section (p<0.05). WOG and Mtwo systems presented similar shaping ability and centering ability in oval-shaped canals. However, WOG presented less transportation than Mtwo at 5 mm from the apex.

Trichodynia: An Update on Definition, Etiopathogenesis, Diagnosis, and Treatment

Published: January 2022

: Trichodynia was elucidated as a distressing, painful sensation of the scalp hair and/or the skin of the scalp that becomes more vigorous when hairs are touched without an underlying cutaneous disease and is frequently associated with hair shedding. It was often more in women than men, directly correlating with hair loss. The etiology of trichodynia is not well-known, but it may be multifactorial. Several possible hypotheses can explain the etiopathogenesis of trichodynia, including enhanced expression of neuropeptide substance P with perifollicular inflammation, psychiatric diseases, and nutritional deficiencies. Currently, there is no specific and effective therapy for trichodynia. Various available treatments included L-cystine-containing oral preparation, topical corticosteroid, low-dose antidepressant, oral propranolol, and botulinum toxin injection. This review article highlights an update of the definition, etiopathogenesis, diagnosis, and treatment of trichodynia.
