Evaluation of Bone Graft (Hydroxyapatite + Platelet-Rich Plasma) Alone and in Combination with Diode Laser in Management of Infrabony Defect.

Objective: The current study looked at how well bone graft (hydroxyapatite + platelet-rich plasma (PRP)) and a diode laser treated infrabony defects. Materials and Method: Twenty patients with bilateral infrabony deficiency were treated in a split-moth evaluation with bone graft (hydroxyapatite + PRP) alone (group I) (control) and bone graft combined with a diode laser (group II) (test). Clinical and radiologic measures such as the relative clinical attachment level (RCAL), probing depth (PD), gingival index (GI), and plaque index (PI) were recorded at baseline, 3 months later, and 6 months later in all patients. Result: At the 6-month follow-up, there was a decline in the plaque index, probing depth, gingival index, and relative clinical attachment level. Conclusion: When compared across groups, the intrabony pocket was significantly reduced with either the bone graft (hydroxyapatite + PRP) or in conjunction with the laser.

Assessment of Clinical and Radiological Outcome of Implant with Two Different Connections Con iguration: A Controlled Trial.

Objective: The objective of the study is to compare two different implant designs having different neck configuration and neck interfaces. Materials and Methods: Fifty subjects were randomly divided into 2 groups, each containing 25 subjects. In Group I, conical connection (CC) (Nobel Biocare) with back-tapered collar dental implant and in Group II, external-hexagon (EH) (Nobel Biocare) with flat-to-flat implant-abutment interface dental implant was used. Radiographic marginal bone crest level and marginal bone loss (MBL) were compared. Results: A significant less MBL was seen in Group I compared to Group II recorded at different intervals of time (P < 0.05). Conclusion: CC implants with back-tapered collar exhibited less MBL as compared to EH implants with flat-to-flat implant-abutment interface.

A Comparative Evaluation of Anesthetic Effectiveness of 4% Articaine vs 0.5% Bupivacaine for Lower Molar Tooth Extraction.

BACKGROUND: Safe and efficient pain control is essential for today's dental practice. This randomized controlled study was conducted to evaluate the effectiveness of 0.5% bupivacaine with 4% articaine in lower molar tooth extraction. METHODS: One hundred subjects were classified into two groups, with 50 samples for each. Group A participants were managed with 0.5% bupivacaine with 1:200,000 epinephrine and group B participants with 4% articaine with 1:100,000 epinephrine for mandibular first and second molar extraction. Criteria such as onset and duration of anesthesia, pain throughout the procedure, pain during injection, and pain after the procedure were evaluated. Systolic and diastolic blood pressure (mmHg) and heart rate (per minute)were evaluated for all participants. RESULTS: There was a faster onset (53.2 vs 83.1 s) and lesser duration of action (216.6 vs 298.4 min) with articaine (group B) compared to bupivacaine (group A). Thirty-eight (76.0%) participants in group A and 44 (88.0%) participants in group B did not require re-anesthesia, whereas 12 (24%) participants in group A and six (12%) participants in group B required one-time re-anesthesia and it was insignificant. CONCLUSION: Articaine has a faster onset but a relatively lower duration of action and requires statistically insignificant but lower re-anesthesia. As a result, articaine anesthesia can be efficiently recommended in oral surgical techniques.

Evaluation of mandibular third molar position as a risk factor for pericoronitis: A CBCT study.

AIMS: The present study was conducted to evaluate mandibular third molar position as a risk factor for pericoronitis. MATERIALS AND METHODS: The present study was conducted on 145 subjects of both genders. The clinical symptoms and signs such as redness, pus discharge, pain, and tenderness over pericoronal flap were assessed. All candidates were subjected to CBCT scan evaluation for a third molar position such as vertical, mesioangular, distoangular, and horizontal type. RESULTS: Maximum number of cases of pericoronitis was observed in the age group 18-28 years (80) followed by 28-38 years seen in 47 cases, and 38-48 years seen in 28 cases. The most common type of impaction was mesioangular seen in 48 females and 42 males, followed by vertical in 22 females and 18 males, distoangular in 8 females and 10 males and horizontal in 2 females and 5 males. Maximum clinical features of swelling, trismus, dysphagia, and enlarged lymph nodes were seen in patients with mesioangular impaction followed by vertical impaction. CONCLUSION: Maximum number of pericoronitis cases was seen in the age group 18-28 years and most commonly mesioangular impactions were observed with pericoronitis.

An Assessment of Factors Influencing the Difficulty in Third Molar Surgery.

BACKGROUND AND OBJECTIVES: Surgical removal of a mandibular impacted third molar is one among the most common oral surgical procedures. The objective of this study was to assess and identify risk indicators influencing extended operation time in relation to the surgical removal of mesioangular impacted mandibular third molar, position A, Class I and to evaluate the incidence of postoperative swelling, trismus, and pain. MATERIALS AND METHODS: A prospective cohort was implemented and the patients who presented for mandibular third molar removal which were impacted in position A, Class I were enlisted for the study. During 1 year between July 2014 and June 2015, a total of 40 patients were enrolled in the study. The evaluation of patient variables and radiographic variables was done preoperatively. Depending on the duration of time taken for an operation, patients were divided into three groups: Group I, Group II, and Group III. Postoperative complications such as swelling, trismus, and pain were assessed in each of the patients. STATISTICAL ANALYSIS: The statistical analysis was done among the groups using Chi-square test, and ANOVA. RESULTS: Among the six variables studied in this study including patient variables and radiographic variables, maximum interincisal opening, external oblique ridge, and root morphology were found to be dependent factors which influence the operating time. Moreover, other variables such as the crown root width ratio and the number of roots were independent factors. Swelling, trismus, and pain were statistically significant among groups and were directly related to operating time. CONCLUSION: We consider that the outcome of surgical removal of mandibular impacted third molar, position A, Class I depends significantly on relevant patients characteristics and radiographic variables which should be evaluated preoperatively as they are predetermined factors to avoid postoperative morbidity.

Evaluation of the efficacy of platelet-rich plasma and platelet-rich fibrin in alveolar defects after removal of impacted bilateral mandibular third molars.

AIM AND OBJECTIVES: This study attempted the evaluation of the efficacy of platelet-rich plasma (PRP) and platelet-rich fibrin (PRF) in alveolar defects after removal of bilateral mandibular third molars. MATERIALS AND METHODS: A total of 30 patients reporting to Department of Oral and Maxillofacial Surgery and having bilateral mandibular third molar impaction in both male and female aged between 18 and 30 years were included in this study. PRF and PRP were placed in extraction site and recalled at 2(nd), 4(th), and 6(th) month postoperatively. Data were statistically analyzed using IBM SPSS software for Windows, version 19.0. IBM Corp., Armonk, NY, USA. RESULTS: This study showed decreased probing depth in PRF group compared to PRP and control one. This signifies a better soft tissue healing of extraction sockets with PRF as compared to the PRP and the control group and increase in the bone density highlights the use of PRP and PRF certainly as a valid method in inducing hard tissue regeneration. CONCLUSION: This study indicates a definite improvement in the periodontal health distal to second molar after third molar surgery in cases treated with PRF as compared to the PRP group and control group. Hence, PRP and PRF can be incorporated as an adjunct to promote wound healing and osseous regeneration in mandibular third molar extraction sites.
