The aim of this article was to present the clinical application of a new, smooth surfaced one-piece bicortical screw implant with\nimmediate loading protocol. An 18-year-old, healthy male patient with a history of total dislocation and replantation of teeth 11\nand 21 in early childhood was admitted to the clinic. Teeth 11 and 21 were extracted, and two long one-piece implants were\ninserted at extraction sockets in one surgical session under local anesthesia. Temporary composite crowns were placed in the\npatient on the same day. After 3 months, the single-phase two-layer impression was made and the composite crowns were\nreplaced with metal-ceramic crowns. After 12 months, satisfactory aesthetic and functional results were obtained....
Mucocele (also known as ranula or salivary gland mucous cyst) of the newborn is a lesion present on the intraoral cavity, with the\npotential to interfere with respiration and feeding. In the present report, a case of mucocele in a 4-month female patient has been\ndescribed. As conventional surgery can be followed by several complications such as intraoperative bleeding, difficulties in wound\nhealing, and maintenance of sterility during surgery, in the present case, the use of diode laser has been planned. A topic anesthesia\nwith lidocaine gel was performed. A diode laser (810nm wavelength, continuous wave mode, power output of 3 watt, and 0.4mm\ndiameter fiber optic) was set for excising the lesion. The tip was directed at an angle of 10 to 15�°, moving around the base of the\nlesion with a circular motion. Theprocedure was completed in 3 minutes. Thepatient was visited with a follow-up of 2 weeks and 4\nmonths after excision. The intraoral wound healed without complications, and no signs of infection or mass recurrence were\nnoted. The histopathological examination confirmed the diagnosis of mucocele. On the basis of the results of the present case\nreport, the use of diode laser can be easily performed also in a noncompliant newborn patient for successful excision of mucocele\nlesions, and checklist of clinical procedures has been described....
Calcium hydroxide removal from the root canal by photon induced photoacoustic streaming (PIPS) compared to needle irrigation\nand irrigation using sonic activation was investigated. Additionally, safety issues regarding apical extrusion were addressed. In\nendodontic treatment temporary intracanal medication like calcium hydroxide should be completely removed for long term\nsuccess. For analysis, 60 artificial teeth were prepared, filled with calcium hydroxide, and divided into four groups. The teeth\nwere assigned to needle irrigation, irrigation using a sonic device, PIPS with a lower energy setting (10 mJ, 15Hz), or PIPS with\na higher energy setting (25 mJ/40Hz). For comparison the weight of each tooth was measured before and after calcium hydroxide\nincorporation, as well as after removing calcium hydroxide using the four different methods. Regarding safety issues another 24\nsampleswere filled with stained calcium hydroxide and embedded in 0.4% agarose gel. Color changes in the agarose gel due to apical\nextrusion were digitally analysed using Photoshop. No significant differences were found for calcium hydroxide removal between\nthe two laser groups. Sonic assisted removal and needle irrigation resulted in significant less calcium hydroxide removal than both\nlaser groups, with significantly more calcium hydroxide removal in the ultrasonic group than in the needle irrigation group. For\napical extrusion the higher laser (25 mJ/40Hz) group resulted in significant higher color changes of the periapical gel than all other\ngroups. PIPS with the setting of 10 mJ/15Hz achieved almost complete removal of calcium hydroxide without increasing apical\nextrusion of the irrigation solution....
Background: Digit sucking can represent untreated anxiety or other emotional problems. The aim of this study\nwas to determine if digit sucking is a predictor of general anxiety and dental anxiety; and if general and dental\nanxiety are associated with caries and oral hygiene status of children resident in sub-urban Nigeria.\nMethods: This was a secondary data analysis of a household survey conducted in Ile-Ife, Nigeria. The level of\ngeneral anxiety and dental anxiety of 450 6 to12 year old children were measured using the Revised Child\nManifest Anxiety Scale and Dental Subscale of the Child Fear Survey Schedule respectively. Presence of digit\nsucking habit, caries and oral hygiene status were determined. General anxiety and dental anxiety scores were\ndichotomized into low and high levels respectively. Logistic regression was conducted to determine if digit\nsucking was a predictor of general anxiety and dental anxiety; and if general anxiety and dental anxiety were\npredictors caries and good oral hygiene status. Adjustments were made for age and sex.\nResults: Digit sucking is not a significant predictor of dental anxiety (p = 0.99) and general anxiety (p = 0.79).\nChildren with high general anxiety (AOR: 5.02; 95% CI: 2.9ââ?¬â??9.74; p < 0.001) and high dental anxiety (AOR: 1.74;\n95% CI: 1.15ââ?¬â??2.65; p = 0.009) had higher odds of having caries and good oral hygiene respectively.\nConclusion: Digit sucking was not a significant predictor of general anxiety and dental anxiety. General and\ndental anxiety however, had effects on the likelihood of having caries and good oral hygiene....
Anterior crossbite is relatively a common presentation in the mixed dentition stage. If left untreated, it can lead to a host of\nproblems and may complicate future orthodontic treatment. One of the major difficulties in performing anterior crossbite\ncorrection in young children is treatment compliance. In most cases, poor compliance is due to the unacceptability of the\nremovable appliance used. This article describes three cases of successful correction of anterior crossbite of patients in mixed\ndentition using short-span wire-fixed orthodontic appliances. This sectional appliance provides an alternative method of correcting\nanterior crossbite of dental origin and offers many advantages compared to the use of removable appliances....
Systemic lupus erythematosus (SLE) is a chronic autoimmune and inflammatory disease affecting multiorgans of human body.\nIndependent studies show that SLE patients had higher caries prevalence compared to non-SLE individuals. However, the\nunderlying mechanisms remain unclear. In present study, we enrolled SLE patients to explore potential factors contributing to\nthe susceptibility of SLE patients to dental caries (such as oral hygiene, salivary function, and oral microbial community). Dental\nexamination confirmed SLE patients were more vulnerable to caries. Although subjects in both groups announced similar oral\nhygiene habits, more dental plaque was found on tooth surfaces of SLE patents as revealed by plaque index. In addition, the salivary\nfunction was impaired in SLE group as salivary flow rate, buffering capacity, and pH were lower among SLE subjects compared\nto healthy controls. Importantly, disturbed microbial community with lower richness and diversity was observed in SLE group, as\nwell as disequilibrium between acidogenic/aciduric pathogens and alkali-generating commensal bacteria. Our data suggest that\nSLE increases patients� sensitivity to dental caries through imposing stress to both host and oral microbes....
