Can the chokeberry juice be used as additional therapy for burning mouth syndrome in menopausal women?

The researchers' aims were to evaluate the effects of chokeberry juice in the treatment of burning mouth syndrome (BMS) and oral discomfort in menopausal women. The following validated scales and questionnaires were used before and after treatment: questionnaire used for selection of research participants with xerostomia, the xerostomia inventory, Visual Analogue Scale (VAS), localization of pain before and after treatment, short-form McGill pain questionnaire. There was statistically significant decrease in number of research participants who felt pain after therapeutic procedure (p < 0.05). Chokeberry juice, as additional therapy for BMS, reduced intensity of characteristic types of pain sensations and oral dryness feeling.

Oral Health-Related Risk Factors Among Students in Southeast Serbia.

BACKGROUND An association between insufficient or irregular oral hygiene with the occurrence of dental caries, gingival/periodontal diseases, and consequently general diseases has been established. The null hypothesis that there is no difference in the oral health status among students in a preclinical medical program and those who went through a clinical medical program was tested. The main objective of the study was to analyze oral health risk factors (oral hygiene practices, attitudes, and behavior) as well as their impact on oral health by using convenience sampling. MATERIAL AND METHODS We investigated risk factors for oral health conditions by examining oral hygiene practices, attitudes, and behaviors among the students in the medical program of the University of Nis, collecting data using questionnaires. The study included 396 students of medicine, dentistry, pharmacy, and vocational studies. Participants filled out the anonymous questionnaire. RESULTS In both groups, parents were mostly employed, with the representation of employed fathers significantly higher in student group 1 (P<0.05), which is also the only statistically significant difference between the groups. In terms of oral hygiene practices, students were most often trained by parents (68.69%). A very high percentage of students brushed their teeth every day (97.22%), and 54.55% did this twice a day. Of the total number of students, 78.28% thought that it was necessary to use interdental brushes/floss/toothpick. The duration of teeth cleaning was 3 minutes in 39.39%, whereas 55.30% thought that it should be longer than 3 minutes. The most common brushing movements were combined movements and were used by 60.35% of all students. Of all students, 253 (63.89%) never smoked, 182 (49.96%) regularly went to the dentist, and 141 (35.61%) visited the dentist 6 months ago. The majority of students, 265 (66.92%), obtained the greatest amount of information about oral and tooth care from their dentist, which was the case in both age groups. CONCLUSIONS This study highlights oral health risk factors among students at the University of Nis. It is essential to determine their oral health knowledge, as it is of great significance both to patients and to students. Also, these students will be the major providers of health services and will be responsible for public oral health promotion. It could help in reformation of the oral health education program. The results of this research indicate that it is necessary to educate preclinical students to solve oral health issues.

Prevalence of Human Cytomegalovirus and Epstein-Barr Virus in Chronic Periapical Lesions.

OBJECTIVE: The aim of this study was to investigate the presence of human cytomegalovirus (HCMV) and Epstein-Barr virus (EBV) in the tissue of chronic periapical lesions, and to compare the results in relation to the symptoms of patients and the size of the lesion. METHODS: Periapical lesions analyzed in the study were collected from the roots of the teeth indicated for extraction. Samples were divided according to the symptoms into groups of symptomatic and asymptomatic, and according the size into groups of small and large lesions. Polymerase chain reaction was used to detect HCMV and EBV. The amplification was performed in a DNA Thermal Cycler (Hybaid). RESULTS: Symptomatic lesions were 7.68 times more likely to be infected with HCMV than asymptomatic lesions (p < 0.001). Large symptomatic lesions were 73.50 times more likely to harbor HCMV than small symptomatic lesions (p < 0.001). Large symptomatic lesions were 7.64 times more likely to be infected with EBV than small symptomatic lesions (p = 0.05). Large symptomatic lesions were 5.38 times more likely to harbor dual HCMV/EBV infection than small symptomatic lesions (p = 0.115). CONCLUSION: Detection of HCMV and EBV in the samples of periapical lesions suggests an important role of herpesviruses in periapical tissue destruction.

Asymptomatic flow of Rosai-Dorfman disease.

INTRODUCTION: Sinus histiocytosis with massive lymphadenopathy is a rare benign self-limiting disease of unknown etiology. The salivary gland involvement, indicating the extranodal character of the disease, often presents a diagnostic dilemma requiring immunohistochemical staining of surgically removed tumor to confirm the diagnosis. CASE REPORT: We report a 43-year-old man presented with an asymptomatic mass in the left mandibular angle. On physical examination, the lesion was described as a painless, mobile, firm-elastic consistency nodule, which measured 4 x 3 cm in diameter, with normal overlying skin. A mass with the same characteristics, dimensions 2 x 2 cm, was also noted in the right parotid region. No other changes in regional lymph nodes were detected. On macroscopic examination the lesion was firm, multilobulated, yellowish and rounded, while on microscopic examination the lesion was composed almost entirely of polygonal histiocytes with abundant cytoplasm, emperipolesis, plasma cells arranged in sheets, and lymphocytes scattered or within clusters. The observed histiocytes were found to be CD68 and S100 protein positive. CONCLUSION: Rosai-Dorfman disease is a beningn and frequently overlooked clinical and pathological entity that may be misinterpreted as a neoplastic disease.

Morphologic and morphometric analysis of alternations in the oral cavity caused by Candida albicans--experimental work.

INTRODUCTION: Candidiasis has become a human disease of increasing importance in the last decades. The aim of the study is to establish pathomorphological alterations caused by the blastospores of the Candida albicans as well as morphometric alterations. MATERIAL AND METHODS: The experiment was carried out on 2.5-month-old rats, weighting 110-130 g. The study sample was divided into the animals infected by a submucous inoculation in the periodontal region and the controls. The gingival specimens were taken, preparations were done and stained by the hematoxylin-eosin and Periodic acid Schiff methods. RESULTS: The following alterations were found out by the stereological analysis: an average volume of nuclei of the gingival epithelial cells was 111.82 microm3 (SD = 25.34) on the first day. A statistically significant increase in the volume of nuclei in the experimental group began to occur from the fourth day (202.97 microm3; SD = 31.16, p < 0.05) and the highest value of the nuclei volume was found out on the eight day of the experiment (316.83 microm3; SD = 40.15). CONCLUSION: Blastospores of Candida albicans are pathogenic for the gingival tissue where they cause degenerative necrotic alterations of the granulomatous character and after the fourth day from the inoculation, the development of the pseudohyphae was observed. The obtained values of stereologic measurement show the acute increase in the volume of nuclei.

Comparative analysis of smoking influence on periodontal tissue in subjects with periodontal disease.

THE AIM OF THE STUDY: The aim of the study was clinical and cytological examination of gingival changes in smokers and non-smokers. Further, specific goals of this study were health promotion in patient, particularly in smokers. METHODS: The anamnesis was taken and clinical examination was conducted on the patients who came on Dental Clinic. During the clinical examination, plaque index (Pl)(16), gingival index Löe-Silness (Gi) and the community periodontal index of treatment needs (CPITN)(17) were done. After diagnosis was established, participants divided into group I -smokers, and group II - non-smokers. The gingival smears were taken for cytological analysis, dried on air, and stained by haematoxylin-eosin method. RESULTS: The values of gingival index (GI)- Löe-Silness and periodontal index (CPITN) were higher in the group of smokers, but plaque index was also higher with statistically significant difference of their values between examined group, with maximum level of significance (p<0,001). The size of nucleus (area, Ferret's diameter and perimeter) was higher in the group of smokers, but differences were not statistically significant. In the group of non-smokers density of nucleus was higher than in non-smokers group, but difference was not statistically significant. CONCLUSION: The values of examined indices showed higher values in smokers group. This finding could show that the level of oral hygiene is higher in the non smokers group. The size of nucleus (area, Ferret's diameter and perimeter) was higher in the group of smokers, but differences were not statistically significant. Teamwork of many different speciality experts is required for better periodontal health of smokers.

RP-HPLC assay of doxycycline in human saliva and gingival crevicular fluid in patients with chronic periodontal disease.

A reversed-phased HPLC method with fluorescence detection was optimized and validated for determination of DOXY in human saliva and gingival crevicular fluid (GCF) with tetracycline as internal standard. Single step extraction with acetonitrile for both types of samples was performed. The separation was achieved at Zorbax Extend-C18 analytical column at 30°C. Mobile phase was consisted of an aqueous phase containing magnesium acetate, ammonium acetate, Na2EDTA, triethyl-ammonium acetate buffered to pH 7.5 with ammonium hydroxide solution and acetonitrile. The volume ratio of the buffered water mixture of salts and acetonitrile was 86:14. Fluorescence detector was set at λex=380 nm and λem=520 nm. Under the optimized experimental conditions, good linearity was found in the range of 5.0-250.0 ng/mL for GCF with LOD of 1.63 ng/mL and LOQ of 4.93 ng/mL and 20.0-500.0 ng/mL for saliva with LOD of 6.36 ng/mL and LOQ of 19.28 ng/mL. This method was successfully applied for determination of DOXY in saliva and GCF obtained from patients with chronic periodontal disease.

A histological evaluation of a low-level laser therapy as an adjunct to periodontal therapy in patients with diabetes mellitus.

Diabetes mellitus (DM) and chronic periodontitis are common chronic diseases in adults in the world population. DM has a strong influence on the oral cavity and represents a risk factor for gingivitis and periodontitis. Low-level laser therapy (LLLT) has proven effective in the reduction of inflammation and swelling. The aim of the present study was to evaluate the efficacy of LLLT in diabetic periodontitis through histological analysis. A total of 300 diabetics with chronic periodontal disease and teeth indicated for extraction were assigned into six equal groups. In the groups 1 and 4, indicated teeth were extracted before treatment, and in the rest of the groups upon completion of the entire treatment. All patients received oral hygiene instructions and full-mouth conservative periodontal treatment. In groups 3 and 6, LLLT was applied (670 nm, 5 mW, 2 J/cm(2), 16 min, 5 days). Histologic findings of gingival tissue treated with LLLT showed expressed healing, as is evident by the absence of inflammatory cells. Tissue edema could not be seen, and the number of blood vessels was reduced. In the gingival lamina, propria pronounced collagenization and homogenization were present. It can be concluded that LLLT has shown efficacy in the treatment of periodontitis in diabetics. Because of more pronounced alterations of periodontium in diabetics, the use of LLLT is of particular importance.

[Association between chronic periodontitis and serum lipid levels].

BACKGROUND/AIM: Periodontitis is a local inflammatory process mediating destruction of periodontal tissues triggered by bacterial insult. However, this disease is also characterized by systemic inflammatory host responses that may contrbute, in part, to the recently reported increased risk for systemic diseases, including an altered lipid metabolism. On the other hand, many people in the world are affected by hyperlipidemia, which is a known risk faktor for atherosclerosis. The aim of this study was to determine the relationship between periodontal disease and blood lipid levels. METHODS: A total of 50 patients with periodontitis included in this study had no documented history of recent acute coronary events. The healthy, non-periodontal subjects (comparison group) comprised 25 subjects. All the patients were periodontology examined and completed a medical history. Dental plaque index, probing depth, gingival index bleeding on probing and clinical attechment levels were recorded. Blood samples were taken on admission for measurements of serum total cholesterol, triglycerides, hight density lipoprotein cholesterol (HDL-cholesterol), and low density lipoprotein cholesterol (LDL-cholesterol). RESULTS: The obtained results showed that mean levels of cholesterol (6.09 +/- 1.61 mmol/L), triglycerdes (2.19 +/- 1.67 mmol/l) and LDL cholesterol (4.09 +/- 1.40 mmol/L) in individuals with periodontitis were higer, and levels od HDL (1.43 +/- 0.51 mmol/L) was lower than those of individuals without periodontitis (4.86 +/- 1.37; 1.14 +/- 0.71; 3.18 +/- 0.64; 1.53 +/- 0.32 mmol/L, respectively). CONCLUSION: This study confirms a significant relationship between periodontal disease, regardless its intensity, and blood lipid levels in the studied population. The results imply that periodontitis may be a risk factor and may contribute to the pathogenesis of atherosclerosis and cardiovascular diseases (CVD). However, future prospective randomized studies have to determine whether periodontal disease is a risk factor for the occurence of CVD.

Low-level lasers as an adjunct in periodontal therapy in patients with diabetes mellitus.

BACKGROUND: Diabetes mellitus (DM) increases the risk of periodontitis, and severe periodontitis often coexists with severe DM. The proposed dual pathway of tissue destruction suggests that control of chronic periodontal infection and gingival inflammation is essential for achieving long-term control of DM. The purpose this study is to evaluate the effects of low-level laser therapy (LLLT) by exfoliative cytology in patients with DM and gingival inflammation. SUBJECTS AND METHODS: Three hundred patients were divided in three equal groups: Group 1 consisted of patients with periodontitis and type 1 DM, Group 2 of patients with periodontitis and type 2 DM, and Group 3 of patients with periodontitis (control group). After oral examination, smears were taken from gingival tissue, and afterward all of the patients received oral hygiene instructions, removal of dental plaque, and full-mouth scaling and root planing. A split-mouth design was applied; on the right side of jaws GaAlAs LLLT (670 nm, 5 mW, 14 min/day) (model Mils 94; Optica Laser, Sofia, Bulgaria) was applied for five consecutive days. After the therapy was completed, smears from both sides of jaws were taken. The morphometric analysis was done using the National Institutes of Health Image software program and a model NU2 microscope (Carl Zeiss, Jena, Germany). RESULTS: Investigated parameters were significantly lower after therapy compared with values before therapy. After therapy on the side subjected to LLLT, there was no significantly difference between patients with DM and the control group. CONCLUSIONS: It can be concluded that LLLT as an adjunct in periodontal therapy reduces gingival inflammation in patients with DM and periodontitis.

Ultrastructural changes in the cemento-enamel junction after vital tooth bleaching with fluoride and fluoride-free agents - a pilot study.

BACKGROUND: The impact of bleaching on the cemento-enamel junction (CEJ) is not well known. Due to frequent sensitivity of the cervical region of teeth after the vital bleaching, the aim of the present study was to evaluate the morphological features of the CEJ of human teeth after application of fluoridated and fluoride-free bleaching agents, as well as post-bleaching fluoridation treatment, by scanning electron microscopy (SEM) analysis. MATERIAL/METHODS: Thirty-five extracted permanent human teeth were longitudinally cut, yielding 70 specimens. Thirty specimens were randomly divided into the 3 experimental groups, and 20 specimens, were used as (2) control groups, each: negative (untreated) control group; positive control group treated with 35% hydrogen peroxide; experimental group 1, bleaching with 10% carbamide peroxide (CP); experimental group 2, treatment with a mixture of 10% CP and fluoride; and experimental group 3, treatment with 10% CP and 2% sodium fluoride gel applied 30 minutes after bleaching. Experimental groups were treated 8 h per day for 14 days. The samples were examined by SEM. RESULTS: The bleaching materials tested caused morphological changes to the surface of the CEJ. There was a statistically significant difference between experimental groups (Kruskal Wallis Test chi-square=11,668; p<0.005). Mean value of experimental group 2 scores showed statistically significant difference from groups 1 and 3. CONCLUSIONS: Bleaching gel with fluorides does not significantly change morphological appearance of the CEJ and represents a better choice than the hard tissue fluoridation process after bleaching.

Cytomorphometric and clinical investigation of the gingiva before and after low-level laser therapy of gingivitis in children.

Gingival epithelial cells are the first physical barrier against periodontal pathogenic microorganisms. Bacterial products may penetrate the epithelium and directly disturb its integrity. We investigated the clinical and cytomorphological status of the gingiva in children with gingivitis before and after low-level laser therapy. The study enrolled 130 children divided into three groups: group 1 comprised 50 children with chronic catarrhal gingivitis who received basic treatment, group 2 comprised 50 children with chronic catarrhal gingivitis who received low-level laser treatment in addition to basic treatment, and group 3 comprised 30 children with healthy gingiva as controls. Oral hygiene and the status of the gingiva were assessed using the appropriate indexes before and after treatment. Inflammation of the gingiva was monitored by cytomorphometric evaluation. Cytomorphometric analysis revealed a statistically significant difference (p < 0.001) in the size of the nuclei of the stratified squamous epithelial cells of the gingiva before and after treatment in chronic catarrhal gingivitis. Evaluation using clinical parameters showed that treatment of gingivitis with basic treatment was successful. Cytomorphometric analysis showed that after basic treatment the nuclei of the stratified squamous epithelial cells of the gingiva were reduced in size, although not to the size found in healthy gingiva. However, after adjuvant low-level laser therapy, the size of the nuclei of the stratified squamous epithelial cells in the gingiva matched the size of the nuclei in the cells in healthy gingiva.

[Low power laser efficacy in the therapy of inflamed gingive in diabetics with parodontopathy].

BACKGROUND/AIM: There is clear evidence on direct relationship between periodontal disease and diabetes mellitus. Many investigations point out greater prevalence and severity of periodontal disease among diabetic patients. During last decade, low level laser therapy has been used in periodontal therapy. It has biostimulative effect, accelerates wound healing, minimizes pain and swelling, and there is almost no contraindication for its usage. The aim of the paper was to investigate the efficiency of low level laser therapy as adjuvant tool in reduction of gingival inflammation in diabetic patients. METHODS: The study incuded 150 participants divided into three groups: group I (50 participants with diabetes mellitus type 1 and periodontal disease), group II (50 participants with diabetes mellitus type 2 and periodontal disease), group III (nondiabetic participants with periodontal disease). Gingival health evaluation was done using gingival index Löe-Silness. Soft and hard deposits were removed, periodontal pockets cleaned and GaA1As low level laser therapy (5 mW) applied five consecutive days. In each patient, low level laser therapy was not applied on the left side of the jaw in order to compare the effects of the applied therapy. After the first, third and fifth therapy and one month after the last visit gingival index was evaluated. Before the first and after the fifth therapy exfoliative cytology of gingiva was done and nuclei areal was analyzed morphometrically. RESULTS: After all investigated periods, gingival index and nuclei areal were significantly decreased comparing to values before the therapy, at both jaw sides (p < 0.001). After the 1st, 3rd and 5th therapy, the t-test showed a significantly decreased gingival index at the lased side of jaw comparing to non-lased side. CONCLUSION: Low level laser therapy is efficient in gingival inflammation elimination and can be proposed as an adjuvant tool in basic periodontal therapy of diabetic patients.

Effect of periodontal treatment on lipoproteins levels in plasma in patients with periodontitis.

OBJECTIVES: Recent epidemiological studies have shown that individuals with periodontitis have a significantly increased risk of developing coronary heart disease. In addition to conventional risk factors, dyslipidemia may be associated with this increased risk. METHODS: We measured concentration of lipids in patients with moderate to severe periodontitis before and 3, 6 and 12 months after local periodontal treatment. A total of 50 participants with periodontitis and 25 participants without periodontitis were included in the analyses. Lipoproteins were measured by using serological analyses of the Central Biochemical Laboratory in Clinical Center in Nis. Periodontal health indicators included the plaque index, gingival bleeding index, and periodontal disease status (defined by pocket depth and attachment loss). Patients were non-surgically treated with mechanical debridement of calculus once a week for 1 month. RESULTS: The results show a significant relation between indicators of poor periodontal status and serum level lipoproteins. Periodontal therapy resulted in a significant reduction of local inflammation and tissue destruction as reflected in reduced pocket depth and reduced bleeding indices. The levels of lipoproteins after therapy seemed to be lower than those reported before treatment in patients with periodontitis compared with healthy ones. Lipoproteins were significantly decreased after treatment (P < 0.005) except high-density lipoprotein cholesterol which was not significantly reduced (P > 0.05). CONCLUSION: This pilot study shows that periodontal disease significantly affects the serum levels of lipoproteins and suggests that following successful periodontal treatment decreases serum lipid concentration. This study suggests also that lipoproteins are possible intermediate factors that may link periodontal disease to elevated cardiovascular risk.

Association between Periodontopathogens and CRP Levels in Patients with Periodontitis in Serbia.

BACKGROUND AND AIMS: Recent epidemiological studies have shown that individuals with periodontitis have a significantly higher risk of developing coronary heart disease, which might be attributed to the complex microbiota in the dental plaque. Periodontopathogens have been reported as risk factors for cardiovascular disease. This study evaluated association of chronic periodontitis and periodontopathogens with CRP in systemically healthy Serbian adults. MATERIALS AND METHODS: Serum C-reactive protein levels were measured in 24 patients with moderate periodontitis, 26 patients with severe periodontitis, and 25 periodontally healthy subjects. Periodontal health indicators included gingival bleeding on probing and periodontal disease status. Patients with moderate periodontitis had low attachment loss and pocket depths of <4 mm. Patients with severe periodontitis had high AL and pocket depth of >5 mm. The control group with healthy gingiva had gingival sulcus of <2 mm and no attachment loss. Presence of periodontopathogens in subgingival plaque samples was analyzed by polymerase chain reaction. RESULTS: The periodontal parameters and CRP levels were significantly higher in the patients with periodontitis. Patients who had both severe and moderate periodontitis had higher mean CRP levels. The percentage of subjects with elevated CRP leves of >5 mol/L was greater in the higher clinical AL group compared to the group with less attachment loss. Presence of periodontopathogens was also associated with elevated CRP levels and poor periodontal status. CONCLUSION: PD and subgingival periodontopathogens are associated with increased CRP levels. These findings suggest that periodontal infection may contribute to systemic inflammatory burden in otherwise healthy individuals.

[Efficacy of hyaluronic acid in the treatment of chronic gingivitis in children].

INTRODUCTION/AIM: Gingivitis is a common occurrence in children and may well be thought as a risk factor for the appearance and progression of the diseases of parodontal tissues. It is thus necessary to react in a timely and adequate fashion to prevent the disease to become serious and produce parodontopathy. The aim of the study was to establish the efficacy of hyaluronic acid in the treatment of chronic gingivitis in children. METHODS: The study enrolled 130 children with permanent dentition. All of the examinees were divided into three groups: group I--50 patients with chronic gingivitis in which only the basic treatment was applied; group II--50 patients with chronic gingivitis in which hyaluronic acid was applied in addition to basic treatment; group III--30 examinees with healthy gingiva (control group). Assessment of oral hygiene and status of the gingiva and parodontium was done using the appropriate indexes before and after the treatment. Inflammation of the gingiva was monitored by way of cytomorphometric studies. RESULTS: The pretreatment values of the plaque index (PI) were high: in the group I PI was 1.94; in the group II PI was 1.68. After the treatment, the PI value was reduced to null in both groups (PI = 0). In the group III PI was 0.17. The bleeding index (B1) in the group I was 2.02 before and 0.32 after the treatment; the BI value in the group II was 1.74 before and 0.16 after the treatment. In the group III BI was 0. In the group I, the Community Periodontal Index of Treatment Needs (CPITN) was 1.66 before and 0.32 after the treatment; in the group II, the CPITN value was 1.5 before and 0.24 after the treatment. In the group III, the CPITN value was 0. In the group I, the size of the nuclei of the stratified squamous epithelium of the gingiva was reduced, although not so much as the nuclear size in the group II of examinees. CONCLUSION. Basic treatment is able to successfully treat chronic gingivitis in children. The use of hyaluronic acid together with the basic treatment can markedly improve the treatment effect.

White blood cell count in different stages of chronic periodontitis.

Periodontal disease is considered to be an inflammatory disorder that is related to the accumulation of oral microbial biofilm and the host response to this accumulation. The host reaction to gingival microorganisms is characterized in part by increase in the polymorphonuclear leukocyte counts, which is one of the most important steps in host defense. Exaggerated leukocytes and neutrophils of host response are a very important component in the pathogenesis of periodontal disease. The purpose of this study was to investigate the relationship between white blood cell count and periodontal disease in subjects with moderate and severe periodontitis and in control subjects with healthy periodontal tissues. Leukocytes for the present study were obtained from peripheral venous blood of 50 patients with moderate periodontitis, 50 patients with severe periodontitis and 25 healthy subjects. The clinical parameters of periodontitis including plaque index, bleeding on probing and gingival index were determined in all study subjects. In both moderate and severe periodontitis, the results indicated a significantly higher count ofneutrophils (P < 0.001), as well as of both lymphocytes and total leukocytes (P < 0.05). The values of clinical parameters (plaque index, gingival index and bleeding on probing) also showed significant between-group differences (P < 0.005 and P < 0.001, respectively). It is possible that there is a significant relationship between total leukocyte count, neutrophil count and different forms of periodontal disease.

The effects of low level laser irradiation on gingival inflammation.

OBJECTIVE: The goal of this study was to analyze the effects of low level laser irradiation treatment and conservative treatment on gingival inflammation. BACKGROUND: It is widely accepted today that the primary etiological factor for the onset of periodontitis is dental plaque, although the exact mechanism of damage remains unknown. Inflammation is a basic response of periodontal tissue to damage and serves as a fast first line of defense against damage and infections. The treatment of gingivitis and periodontitis has gone through various stages: from the simplest, classical treatment methods, through improved radical interventions, to a new era marked by laser technology. Low level laser irradiation has an anti-inflammatory effect, both general and local. MATERIALS AND METHODS: The research was done on patients who had chronic periodontal disease (mild periodontitis) with expressed clinical symptoms of gingival inflammation. All patients in the study underwent conservative treatment. After conservative therapy, the patients from the experimental group were subjected to 10 low level laser treatment sessions. Both groups underwent regular follow-up visits 1, 3, and 6 months after treatment, which involved only clinical examination using plaque index (PI), gingival index (GI), and bleeding on probing index (BOP index). RESULTS: A considerable decrease in all three indexes after the application of both therapies was noticed. The follow-up visits revealed the difference in index values. With laser therapy, the values of indexes decreased steadily, whereas with conservative therapy they increased up to a certain point, but did not reach the pre-therapy values. CONCLUSIONS: A general conclusion can be drawn that low level laser irradiation (semiconductor, 670 nm) can be used as a successful physical adjuvant method of treatment, which, together with traditional periodontal therapy, leads to better and longer-lasting therapeutic results.

Dentinal hypersensitivity following scaling and root planing: comparison of low-level laser and topical fluoride treatment.

The aim of this study is to compare the effectiveness of low-level laser irradiation to traditional topical fluoride treatment for treatment choices of dentinal hypersensitivity following scaling and root planing. The experimental group (15 patients) was treated with low-energy-level diode laser at each site of dentinal hypersensitivity following scaling and root planning. The control group (15 patients) received topical fluoride treatment (protective varnish for desensitization). All the patients were treated at baseline visit, and then at day 2 and 4 after the initial treatment; the pain was subjectively assessed by the patients as strong, medium, medium low, low, or no pain. Total absence of the dental hypersensitivity was reported in 26.66% of the examined group even after the second visit, compared to the control group where complete resolution of the hypersensitivity was not present after the second visit in any of the treated cases. Complete absence of pain was achieved in 86.6% of patients treated with laser and only in 26.6% in the fluoride treated group, after the third visit. Based on our findings, we conclude that low-energy biostimulative laser treatment can be successfully used for treatment of dental hypersensitivity following scaling and root planing.

Incidence and treatment outcome of oral lichen planus in southeast Serbia in a 10-year period (1997-2007).

BACKGROUND/AIM: Lichen planus is a chronic, immunologic, mucocutaneous disease with a wide range of clinical manifestations. The aim of this retrospective study was to evaluate the most common forms of oral lichen planus (OLP) and its symptoms and to describe treatment responses in patients during 10-year period. METHODS: The study was conduced on 163 OLP patients who came in the Department of Oral medicine and Periodontology between 1997 and September 2007. Each case was classified into one of four clinical subtypes: reticular, atrophic, erosive-ulcerative, bullous. RESULTS: There was no significant difference in patients age. Women were found to be significantly more likely to have OLP (p < 0.001). Corticosteroids were effective in reducing symptoms, erythema and healing ulcers. Improvement was shown over a long term in 61.35% patients. Over the long term 38.65% patients maintained the same type of OLP or it became a more severe type. Two patients (1.22%) developed oral carcinoma during the follow-up period. CONCLUSION: The response of patients with erosive OLP to a short course of systemic corticosteroids often was quite remarkable. However, symptoms and signs tended to recur after this treatment. Periodic examinations, patient education, medical treatment, monitoring of side-effects as well as follow-up biopsies are necessary for management of OLP patients.
