The extraction of mandibular third molars is a traumatic procedure accompanied by marked clinical symptoms in the postoperative period. The aim of the present study was to determine the effects of the removal of a partially impacted mandibular third molar on the masticatory efficiency in patients in the early postoperative period.
Material and methods. A total of 47 participants, divided into two groups, took part in this pilot study. The first group included 33 patients with a mean age of 18.3 years (SD = 0.9 years), defined as the Control group; the second group involved patients with a mean age of 33.3 years (SD = 1.86), referred to as the Clinical group. The masticatory efficiency of the Clinical group patients was objectively double-checked using a Protab® test bite: once during the preliminary examination (prior to extraction of the wisdom tooth) and again 7 days after the surgical removal of the wisdom tooth. A sieve analysis was applied to determine the artificial test bite particle size and size distribution following mastication. Feedback on the Clinical group patients’ assessment of any subjective complaints was obtained through a questionnaire containing two questions considered relevant to patients’ masticatory efficiency. The data from the sieve analysis of each fraction were analyzed using the Statistics Software Package for Epidemiological and Clinical Research (IBM SPSS V.20.00).
Results. The data processing of all parameters tested prior to and after extraction of the wisdom tooth revealed statistically significant differences. Only the duration of chewing after the third molar extraction matched the chewing duration in the healthy control subjects (p = 0.198). The analysis of the feedback on the self-assessment of patients from the Clinical group demonstrated that prior to extraction all subjects (100%) experienced pain to a varying degree, whereas in half of the patients (50%) the pain disappeared following extraction. The Spearman’s test for correlation between mean particle sizes as well as the questionnaire feedback indicated a strong positive relationship with food trapping. Accordingly, the larger mean particle size was linked to the self-assessment of food trapping around the wisdom tooth prior to extraction (Spear-man’s Rho = 0.57, p = 0.032). There was also a correlation between the chewing time and the sensation of pain in the teeth adjacent to the extraction wound. The results suggested that the shorter duration of chewing was associated with a greater sensation of pain (Spear-man’s Rho = -0.61, p = 0.026).
Conclusion. The eruption of mandibular third molars causes difficulties in the masticatory process. A positive trend was observed towards normalizing of the chewing duration following extraction (t = -1.356, p = 0.198).
The periodontal ligament injection appears to be the most consistently reliable in achieving clinically adequate pulpal anaesthesia. Materials and Methods: 130 inferior molar teeth; technique: The tooth was first cleaned with chlorhexidine 0.2% solution. The penetration of the ligament is performed with special intraligamentary needle (30 G - 9, 17,21 mm) “sliding” along the side of the tooth, 300º angle between the needle and the tooth, having taken the care of determining support points which will prevent the needle from twisting. The penetration must be deep enough to obtain the seal required for the injection, injection for each root in particular points; volume of solution per root is 0.2-0.4 ml. Results: In 125 cases the technique was absolutely efficient. In only 5 cases with pulpitis chronica ulcerosa there was need for additional intrapulpal anesthesia. Conclusions: The method could be used as a primary anesthetic method for endodontic treatment.

The technology advance in recent years determines the need of construction of modern appliances for early diagnosis of dental caries, which are categorized by great precision, non-invasiveness, easy usage and wide availability. Such non-invasive and accurate tool for diagnostics of caries is Caries Detector (LED), Bulgarian product by “Optica Laser”. The detector emits a specific wavelength of near ultraviolet light, which causes fluorescence to porphyrins - metabolic products of the life cycle of caries-inducing bacteria. The purpose of the study is piloting a new diagnostic tool for detection and monitoring of caries excavation based on fluorescence - LED UV caries detector of company “Optica laser”. Subjected to examination by caries indicator dye and UV caries detector were sixty permanent teeth with deep dentine caries. Two methods were used to assess the dentin caries - UV fluorescence detector of “Optica Laser” and staining with caries indicator - dye (Sable ™ Seek®). It was found that among all sixty teeth, the fields, closed by margins of carious process overlap. Fifty-four of tested teeth has shown bigger field of images with staining method and six - smaller in comparison to the fluorescent method. Ultraviolet fLuorescence caries detector of “Optica Laser” company is affordable and easy applicable method for controlled excavation of dentine caries. The detector can be used in daily dental practice equally with other methods. The unit has a number of advantages - non-invasiveness, lack of interaction with tooth structures, speed, reliability, efficiency, predictability and repeatability of results.

Provision of quality health services to population of the rural areas with limited access to dental treatment and educating dental students in high standard of professional conduct when delivering health services to the population, represents the main reason for the foundation of a dental college in an area like Mangalore. The purpose of this study was to assess the satisfaction of patients visiting the dental college clinics. A cross-sectional study was conducted between May 1 and July 31, 2017. A questionnaire, covering 4 items: patient-dentist relationship; efficiency of the general clinic; patients perception of dental care quality; college healthcare opinion, was distributed to 400 patients visiting the dental clinic. Data were treated statistically using overall percentage distributions and Fisher exact test. The mean percentage of agreement for the 4 items was 85.86 ± 24.51% denoting a high level of satisfaction. Fisher exact test showed (p < 0.01) statistically important difference between first time and multiple time visitors answers. Majority of the patients were satisfied with the clinical settings and the benefits of the fast delivered treatment. The quality of the services was appreciated by the majority of visitors. The attitude of the providers of healthcare was perceived as very friendly and gentle. The assessment of patients’ contentment and perception of healthcare services could be an efficient tool to evaluate the overall activity of an educational healthcare institution.
