IMPACT OF PERIODONTAL HEALTH STATUS ON THE ORAL HEALTH RELATED QUALITY OF LIFE IN SULAIMANI CITY BY USING ORAL HEALTH IMPACT PROFILE

Osamah Algodi — 2024-06-30

Aim:

The objective of this study is to create a valid and reliable Kurdish version of Oral Health Impact Profile-14 (OHIP-14) and to find the impact of periodontal health status on oral health related to quality of life (OHRQoL).

Method:

OHIP-14 was translated and checked for validity and reliability during the pilot study which involved 39 participants. After validation of the newly created Kurdish version of OHIP-14, 323 individuals participated in this questionnaire-based cross-sectional study which involved documentation of their demographics and periodontal clinical parameters for all participants by the researcher using William’s periodontal probe. The newly fabricated Kurdish version of OHIP-14 was filled by the participants themselves.

Results: Among participants, the total mean of OHIP-14 and the mean values of all subscale scores significantly increase with increasing the severity of periodontal diseases (P≤ 0.05) except for psychological discomfort, and physical disability. It was found that there was a statistically significant strong positive correlation between periodontal parameters (PI, BI, PPD, and CAL) and quality of life (p<0.0001).

Conclusion: Based on the study's findings, it can be inferred that periodontal diseases pose negative impacts on the quality of life (QOL), with a more pronounced effect observed in participants suffering from severe periodontal diseases.

Efficacy of silver diamine fluoride on immediate and delayed adhesive strength of resin composite to sound dentin of permanent teeth: an in vitro study

Shaymaa Ali Abdul-Razzaq — 2024-06-30

Objectives: How silver diamine fluoride affected the immediate and prolonged adhesive resin composite's resistance to sound dentin of permanent premolars. Procedures: Three groups were identified (total number=30). The manufacturer's recommendations were followed while applying adhesive resin to the dentin surfaces in Group A after they had been etched. In Group B and C, dentin surfaces were treated with silver diamine fluoride and 0.05% NaF respectively. Then etched and bonded as for the control group. Then resin composite build-ups were created. Following this, each group was divided into two subgroups (for each group n=5), subgroup 1 underwent a shear bond strength test by universal test machine after 24 hrs, subgroups 2 the test was done after thermocycling process (300 cycles). The mode of failure was also examined. Results: The type of dentin surface treated with SDF solution was significantly affect shear bond strength (p=0.000) for both periods (immediate and prolonged). However, there were no significant difference between NaF group and control group on shear bond strength (p<0.05) in immediate and prolong periods. On other hand there were statistically no significant differences between immediate and prolonged shear bond strength in SDF group (p=0.850),

NaF group (p=0.637) and control group(p=0.794) When dentin surfaces were treated with silver diamine fluoride , there were more adhesive failures not as 0.05% NaF and control group which showed more mixed failures. Conclusion: silver diamine fluoride significantly reduced bond strength of etch and rinse adhesive system. Pretreatment with NaF maintained the shear bond strength of the adhesive to dentin after 300 thermal cycles.

Development of Microstructure on Titanium Implant Surface Using CO2 Laser Processing

Ali N. Ahmed Hussein — 2024-06-30

Background: Dental biomaterials made of titanium are commonly used. It depends on the implant surface texture to improve fixation and prevent the unwanted adhesion of bone cells. This study aimed to investigate whether continuous laser beam carbon dioxide (CNC - CO₂) lasers produce specific textures on titanium surfaces with micrometer-sized indentations that influence cell behavior. Materials and method: (CNC - CO₂) red laser device; with a fundamental wavelength of λ=10600 nm and power pulses of 34 W were applied, and textures on the surface of titanium discs were achieved. Results: Excellent degrees of uniformity and repeatability were achieved for the desired portions of the surface by creating different surface textures. The surface topography and chemical composition of the specimens were investigated by scanning electron microscopy, electron dispersive spectroscopy, X-ray diffraction, and surface roughness measurements. Also, a laser power of 34 watts raised the surface roughness, Ra (1.71 nm), and Rz (1.99 nm). Conclusion: Titanium surface textures with unique qualities can be formed in response to an increased heat input. When excessive laser power was used, the measured roughness increased because of instantaneous re-melting. The use of a right continuous-wave (CNC - CO₂) laser on titanium used in dental implants can form specific surface textures.

Saja Abd Almunaf Fadhil — 2024-06-30

Background: The import of the rough surface makes the application of several elements to enhance this feature vital for the adhesion of soft liners. Aim: The study's goal was to to ascertain the impact of copper oxide nanoparticles added in two ratios to heated-cured acrylic resin and fiber laser surface treatment on surface roughness. Materials and methods:60 acrylic specimens in the shape of discs were manufactured and divided into three groups: one received no addition; the other two received the addition of 0.3% CuO NPs; and a third group that received the addition of 0.5% CuO NPs. Each group was divided into two categories: those that were laser treatment and those who did not. The surface roughness test was then examined using a roughness tester called a profilometer. Results: The average roughness values were high for the control groups and low for the CuO NPs 0.5% groups. The mean values in the laser-treated groups had greater roughness than the control groups, according to the laser application.Conclusion:. As the fraction of CuO NPs increased, the surface roughness reduced. The laser treatment also reduced surface roughness.

Cone Beam CT Description of Mental Foramen Variants: A Review

Nuhad A. Hassan — 2024-06-30

The mental foramen (MF) is a crucial marker for local anesthetic, surgical, and implantology treatments. After passing through the mandibular canal, the inferior alveolar nerve and blood vessels exit the MF as the mental vascular nerve. On radiographs, MF appears as a round or oval area of radiolucency inferiorly to the corpus mandible on the lateral sides (left and right). Consideration must be given to its morphology, location, and anatomical variances to minimize mental nerve harm. The focus of this literature review is to find out whether cone beam CT (CBCT) can accurately evaluate MF anatomy implantation and increase the clinician's understanding of this critical topic. Evidence-based research published between 1987 and 2022 was looked for in the literature using MEDLINE (PubMed), Web of Science, Scopus, the Iraq Virtual Science Library, and manual investigation of more sources. This was done to find articles that might be relevant. Between the two premolars, or apically to the second premolar, was where the MF was located most of the time. Men had larger mental foramens than women did, on average. Males tended to have a longer anterior loop than females. More frequently than panoramic, CBCT correctly identified the anterior loop and accessory MF.
